I have read through ALL the posts that mention integration of Iron Python into Visual Studio and I have to admit that I am now more confused than before I started. From my perspective it seems that the IP website actually exacerbates the confusion by NOT stating the obvious.

Just so you know: I want to know if the latest beta version (IP v2.00 or any version) integrates into the full release version Visual Studio 2008 and I can't find a clear cut answer to this question anywhere!

Sure, I have read the Iron Python Studio page and yes, I do know that you can build a standalone VS look-a-like [isolated] version running in a Visual Studio Shell - which is fine if you don't have Visual Studio installed. But what if you do? I have Visual Studio 2008 installed - so does IP automatically integrate with it upon installation? If it doesn't what do I have to do to get it to happen without wrecking my Visual Studio installation? 

For example, Microsoft says that you can get IP working in BOTH isolated AND integrated modes ???? Is this still true of the latest release candidates ? Visual Studio 2008 Shell (Isolated) is listed as a "prerequisite" for Python Studio .... which obviously doesn't look like it will work if you have VS 2008 already installed. So can you use Visual Studio Shell (Integrated) instead?? So many questions .... so few answers. (it sort of looks like we haven't advanced much beyond the days when IP was first offered as an "Integrated" component of Visual Studio --- which sort of worked sometimes ... a little bit ... if you were really lucky.

There seems to be such a mass of conflicting information out there which is all so unnecessary - all it takes is for one of the developers to post a clear and unequivocal statement about this issue on IP website. Problem solved! If IP integrates right now then fine .... if it doesn't then I will wait until it does. What I can't afford to do is stuff up my current VS installation experimenting with something that I have no idea is going to work or not. 

Thanks in anticipation for any forthcoming "enlightenment"!

Message-ID: <47CBCF72.8060703@zeomega.com>

Hi,
I am having 2.0 alpha 8 of IronPython Binaries. I downloaded the wrapper 
changes with comment "Fixed constructor to call __init__" version no. 
7386 
<http://www.codeplex.com/coils/SourceControl/DownloadSourceCode.aspx?changeSetId=7386> 
from
http://www.codeplex.com/coils/SourceControl/ListDownloadableCommits.aspx
As soon as I create .dll file using MakeModule.py, I m renaming the py 
file. Now from ironpython interpreter i m trying to import dll file and 
create instance.
It is failing to create instance,

 >>> import clr
 >>> clr.AddReference('IronPythonDLL.dll')
 >>> import IronPythonDLL
 >>> IronPythonDLL.IronPythonClass
 <class 'IronPythonDLL.IronPythonClass'>
 >>> o=IronPythonDLL.IronPythonClass()
Traceback (most recent call last):
  File IronPythonDLL, line unknown, in .ctor
  File IronPythonDLL, line unknown, in InitClass
  File , line unknown, in ##26
TypeError: Value cannot be null.
Parameter name: scriptSource

Do we need to have py file also in the same directory along with dll?

Thanks,
-Suma.

IronPythonStudio is developed by Clarius Consulting Labs (http://www.codeplex.com/clarius), and I'm a little unsure as to whether they monitor this list.  Have you tried contacting them directly about your question(s)?  If not, I found an email address (info at clariusconsulting.net<mailto:info at clariusconsulting.net>) on their site that might be helpful.

An alternative you might want to also try is using the IronPython Community Technology Preview for ASP.NET (http://www.asp.net/ironpython/).  This installs directly into the full release version of Visual Studio 2008,  is based on IronPython 2.0 Alpha 1 or 2, and provides features such as Python intellisense for VS.

Dear "cyberpro60",
 
I, too, have run into your problems and share your experiences.
Unfortunately, it seems that the maintainer of IPStudio is not answering
e-mail on this list although others, such as Michael Foord, have been
kind enough to answer whatever questions they can about IPStudio.
 
Here is what I have discovered from playing with IPS:
 
- IPS is a new, isolated version of the IronPythonIntegration VSX
example project from the VS SDK's.  As far as I can tell, IPS cannot be
integrated into the full VS, thus making it more difficult to use IPY
with static languages such as C#.  IronPythonIntegration is still
available and may be able to integrate with the rest of VS, but I have
not yet tried it.
 
- IPS will not hurt any installed versions of VS.  I have three
different versions installed, and none of them has been hurt at all.
 
- I could not get IPS to work with 1.1.1.  There's a directory under
where IPS is installed that has IronPython.dll and IronMath.dll in their
1.1.0 versions.  Replacing them with 1.1.1 didn't produce any runtime
changes.
 
- Microsoft's website claims that you can build language backends that
use both the isolated and integrated modes.  However, IPS's website only
states that you need the isolated mode.  It's mum about using integrated
mode.
 
- IMHO, IPS is still very much an "alpha" product.  While it does offer
quite a bit of functionality, I was unable to perform many common VS
tasks (creating references to projects or stand-alone DLL's, using UI
widgets that require resources, deleting files from a project, and
others) that are needed in larger projects.  I found it particularly
strong in creating WinForms forms and dialogs whose Python code can then
be pulled out of IPS and used with minimal changes in the rest of your
application.  However, I do advise writing any code for your UI outside
of IPS.  Any syntax or reference errors cause the GUI builder to
disappear until you fix the problem and then reload the GUI editor.
 
Hope that helps,
 
Rocco

For integrated mode you can use the VS SDK sample of IronPython which IPS is based off of.  But it's more onerous as you need to build the sample it's not just something you download and install.  I do agree though that this is an alpha product - after all at its core is just a sample.

While we're on the subject I'll just point out the developer position we're hiring for (http://members.microsoft.com/careers/search/details.aspx?JobID=8BEEE2C2-A95D-41C6-9075-CF6347EE07F1) specifically calls out us wanting to include VS IDE support.  So this is something we want to do but we need someone to do it :).

Dino,
 
That sounds great.  Robust dev tool support would really help IPY.  
 
One thing that I would recommend is support for integrating IPY with
full VS.  That would easily allow developers to exploit the full power
of .NET with IPY and whatever other languages they choose.
 
Rocco

pack, which will add IP support to Visual Studio.  You might also be

Message-ID: <fcfffa570803040923l11f8013did9b51478ecd929a7@mail.gmail.com>

Hi,

 I'm trying to use callback function of dll. The API has VB.NET
definition for callback:

Public Class FosdkApi
...
   ' set callback function
    'FOSDKLIB_API BOOL WINAPI FOSDKSetCallback(IN INT nCamIndex,
    '                                          IN INT (CALLBACK
*pCallbackFunc)(VOID *pContext, DOUBLE SampleTime, BYTE *pBuf, LONG
lBufferSize)
    '
                IN VOID *pCBContext);

    Public Declare Function FOSDKSetCallback Lib "FOSDK" (ByVal
nCamIndex As Long, ByVal pCallbackFunc As Long, ByVal pCBContext As
Long) As Long

 Help(FosdkApi.FOSDKSetCallback) prints:

Help on built-in function FOSDKSetCallback

 |  FOSDKSetCallback(...)
 |          Int64 FOSDKSetCallback(Int64 nCamIndex, Int64
pCallbackFunc, Int64 pCBContext)

 So how I can use that?

Calling it isn't really the interesting part, the interesting part is what arguments do you pass to it.

To call it you just need to import the class that the function is defined in.  You can do that using:

import clr
clr.AddReference('VBAssemblyName')
from VBNamespaceName import *

where VBAssemblyName is the name of the VB assembly and VBNamespaceName is the name of the namespace this type lives in.  From there you should be able to do:

VBTypeName.FOSDKSetCallback(...)

Then the question becomes what do you pass for nCamIndex, pCallbackFunc, and pCBContext.

But before we go there there's a few interesting things about the signatures.  First is that they're declared as taking Int64's instead of IntPtr's.  If this is your own DLL then you probably want to change these to IntPtrs so they're passing the right size data on both 32-bit and 64-bit platforms.  Then your callback function would look something like:

Public Declare Function FOSDKSetCallback Lib "FOSDK" (ByVal nCamIndex As IntPtr, ByVal pCallbackFunc As Long, ByVal pCBContext As IntPtr) As Long

The 2nd oddity is that pCallbackFunc is not taking a delegate.  That means you'll need to manually call Marshal.GetFunctionPointerForDelegate on a delegate object.  Which also means you're going to need to manually construct the delegate object.  Again if you can change the signature you probably want to have this taking a delegate typed something like (using the C# syntax here):

delegate int MyDelegate(IntPtr pContext, double sampleTime, IntPtr pBuf, int lBufferSize);

Then your VB function would end up looking something like:

Public Declare Function FOSDKSetCallback Lib "FOSDK" (ByVal nCamIndex As Long, ByVal pCallbackFunc As MyDelegate, ByVal pCBContext As IntPtr) As Long

>From there you should be able to do:

def myCallback(context, sampleTime, buffer, bufferSize):
        print context, sampleTime, buffer, bufferSize

from System import IntPtr
FOSDKSetCallback(0, myCallback, IntPtr.Zero)

The only interesting thing then is what you need to pass in for nCamIndex, hopefully the library documentation will explain that :)

If you can't change the signature you'll still need to define the delegate type somewhere (which you can't do from IronPython).  Then your call will probably end up looking like:

from System import Marshal, Int64
FOSDKSetCallback(0, Int64(Marshal.GetFunctionPointerForDelegate(MyDelegate(myCallback))), 0)

 Thank you for fast answer.

 Unfortunately the "fosdk" library is from vendor and I can't change
that. The values of parameters are non-issue, I was lost with the
declaration of callback function and passing the function to
FOSDKSetCallback.

 I defined my own delegate (or copied from example I found from documentation):

Imports System
Imports System.Runtime.InteropServices

public class MyDeleg

Public Delegate Function MyCallback(ByVal pCBContext As Integer, ByVal
SampleTime As Double, _
                                          ByVal pBuf As IntPtr, ByVal
lBufferSize As Integer) As Integer
End Class

 Compiled it and all seemed go OK until the conversion to Int64, so I
got to this:

from System.Runtime.InteropServices import Marshal

FOSDKSetCallback(0,
Marshal.GetFunctionPointerForDelegate(MyDelegate(myCallback)).ToInt64(),
0)

 Seems pretty ok for now, next I've to figure out how to get the whole
system working and start receiving callbacks, but that's different
problem..

 Some more VB.NET samples:


'Delgate for callback function
Public Delegate Function MyCallback(ByVal pCBContext As Integer, ByVal
SampleTime As Double, _
                                          ByVal pBuf As IntPtr, ByVal
lBufferSize As Integer) As Integer

<snip>

    Private cb As MyCallback    'If the callback is called
asynchronously, you have to ensure that the
    'callback delegate is alive as long as the function poitner is needed.

<snip>

cb = AddressOf MyCallbackFunc

<snip>

FosdkApi.FOSDKSetCallback(g_iCrntCam, cb, 12)

<snip>

    Public Function MyCallbackFunc(ByVal pCBContext As Integer, ByVal
SampleTime As Double, _
                                          ByVal pBuf As IntPtr, ByVal
lBufferSize As Integer) As Integer


        sTime = SampleTime
        bSize = lBufferSize

        ThreadPool.QueueUserWorkItem(AddressOf ShowCallbackMsg)     '
show messages in a seperate thread

        Return 1
    End Function

Would it be possible to implement this property? I'm trying to implement

either (1) depending on a custom IronPython or (2) reflecting the real 
IronPython half to death.

For now, I'm just going to assume that all files have been opened for 
reading, so I can get some useful functionality without it; still, I'd 
be very grateful if you would slip this into a nearish-future release 
(or, ofc, tell me what I failed to notice that makes my request

You mean dict? This works:

>>> from System.Collections.Generic import *
>>> a = {'a':23, 'b':42 }
>>> b = Dictionary[object,object](a)
>>> b['a']
23
>>> b.__class__

You'll need to download the Silverlight 2 SDK.  After installing that you'll get all the necessary components installed into something like C:\Program Files\Microsoft SDKs\Silverlight\v2.0\Libraries\Client.  Also installed is an extremely useful tool called Chiron which you'll find somewhere around C:\Program Files\Microsoft SDKs\Silverlight\v2.0\Tools\Chiron.  Chiron can take your .py file and produce a .xap which includes the IronPython & DLR DLLs using the /zipdlr command line option.  You can also use it to serve http requests and automatically serve up the .xap and let you just edit the files.

So once you're ready to make your xap the directory you point at should contain a .py file (I'm not sure what the multi .py file experience is like, but w/ a single file the it doesn't seem the name matters).    The simplest thing to put in there is:

from System.Windows import Application
from System.Windows.Markup import XamlReader

Application.Current.RootVisual = XamlReader.Load("someXaml")

You can see this from the Ruby perspective over at http://www.iunknown.com/2008/03/dynamic-silverl.html

There's various options on how to deploy the DLLs, and you can get into manifest files to deploy additional DLLs, but hopefully that'll get you started.

hi Dino
Thanks for your reply.
But I try my sample (look attachment), It can't run! Is my code mistake ?

*IronPython code:*
from System.Windows import Application
from System.Windows.Markup import XamlReader
class App:
   def __init__(self):
      Application.Current.RootVisual = XamlReader.Load("app.xaml")
      self.scene = Application.Current.RootVisual.grid
   def start(self):
      # TO DO: Replace this with your application start logic.
      self.scene.message.Content = "Welcome to Silverlight and IronPython!"
App().start()
*XAML code:*
<UserControl x:Class="System.Windows.Controls.UserControl"
            xmlns="http://schemas.microsoft.com/client/2007"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <Grid x:Name="grid" Background="White">
        <TextBlock x:Name="message" FontSize="30" />
    </Grid>
</UserControl>

Hi,

 I got my callback eventually working and found one bug/problem:

 If the callback function returns invalid type (eg. None), the
IronPython crashes:

Unhandled exception:
Traceback (most recent call last):
  File , line 0, in System.Int32(Int32, Double, IntPtr, Int32)##154
TypeError: Cannot convert NoneType() to Int32

 And then Windows displays the "program crashed - report to Microsoft" -dialog.

One thing that might help is running w/ -X:ExceptionDetail to get the full .NET stack trace.

I also suspect this exception must be coming from the finalizer thread or from a newly created thread.  Is your app multi-threaded?  If you create threads w/ Python's thread module then your threads won't rip the process.  In .NET 2.0 the CLR started ripping the process whenever there's an unhandled exception but we wrap new threads w/ an exception handler when starting from thread.

Other than the fact that it looks like it's on a new thread though it looks like you're calling a method with null as the value and it's expecting an int32.  Unfortunately we're not giving you a very useful stack trace.  Seeing the full .NET stack trace would be interesting because there's probably something we can do to make this better.

One problem is that XamlReader.Load takes the string of XAML and not a filename.  But there's something about the XAML that isn't working right too.  I'm no XAML expert but simplifying it to the code below works, you can probably build something up from that.  Personally for my Silverlight hacking I've just been building up the tree programmatically from Python code even though that's uncool :).

from System.Windows import Application
from System.Windows.Markup import XamlReader

Application.Current.RootVisual = XamlReader.Load("""
<Canvas Width="100" Height="100" xmlns="http://schemas.microsoft.com/client/2007"  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
        <TextBlock FontSize="30" Text="hello world"/>
</Canvas>""")

Is vs 2008 much better suited to IronPython? Can I now do everything in
IronPython that I could do in C#? Can I get by with XP pro, or would Vista
Ultimate or Server 2008 (both of which I also just got), be better. I assume
all I need on XP Pro is .net 3.5. I would prefer doing everything in

VS 2008 doesn't ship with support for IronPython.  There was a recent thread here about VS integration - check out http://search.live.com/results.aspx?q=%22integration%3A+now+i+am+totally+confused%22&mkt=en-us&scope=&FORM=LIVSOP for more information.

As for XP vs. Vista it shouldn't make much of a difference.

 I'm testing inside the interactive shell, there are no threads
created by me but I think the DLL I am using uses threads.

 I think the this problem is originated from my own error, when I
defined the callback function with no return value (it is expecting
Int32). When return value is defined it runs fine.  The exception is
raised after the callback function has been executed first time by
library.

Here's the output with -X:ExceptionDetail and no return value defined
inside the callback function:

Unhandled exception:
Cannot convert NoneType() to Int32
   at IronPython.Runtime.Converter.ConvertToInt32(Object value)
   at System.Int32(Int32, Double, IntPtr, Int32)##162(Object , Int32 , Double ,
IntPtr , Int32 )
TypeError: Cannot convert NoneType() to Int32

Unhandled Exception: IronPython.Runtime.Exceptions.ArgumentTypeException: Cannot

Hello guys,

I would like to create Silverlight 2 applications *without* using chiron 
to create and deploy them. How do I specify the Python application file?

I see that I can still use Silverlight.js and the 'createObjectEx' 
function to initialise the Silverlight control in my html. How do I 
specify in 'app.xaml' the Python file to load?


function createSilverlightEx()
{ 
    Silverlight.createObjectEx({
        source: 'app.xaml',          // Source property value.
        parentElement:parentElement,    // DOM reference to hosting DIV tag.
        id:'myPlugin',                  // Unique plug-in ID value.
        properties:{                    // Plug-in properties.
            width:'1024',               // Width of rectangular region 
of plug-in, in pixels.
            height:'530',               // Height of rectangular region 
of plug-in, in pixels.
            inplaceInstallPrompt:false, // Determines whether to display 
in-place install prompt if invalid version is detected.
            background:'white',         // Background color of plug-in.
            isWindowless:'false',       // Determines whether to display 
plug-in in windowless mode.
            framerate:'24',             // MaxFrameRate property value.
            version:'1.0'},             // Silverlight version.
        events:{
            onError:null,               // OnError property value -- 
event-handler function name.
            onLoad:null},               // OnLoad property value -- 
event-handler function name.
        initParams:null,                // initParams property value -- 
user-settable string for information passing.
        context:null});                 // Context value -- passed to 
Silverlight.js onLoad event handlers.
}

Thanks

Michael

As far as I can tell (!) your blog only shows how to create a Dynamic
Language Silverlight 2 application using 'app.xap' created with Chiron. I
want to be able to create an application *without* Chiron which is deployed
as text on the server (one of the great advantages of using Dynamic
Languages with Silverlight as explained by Jim Hugunin at Mix07...).

This means using a 'Silverlight.createObjectEx' call from Javascript in the
webpage - where I can pass in the name of the xaml file to load. What I
don't know is how in Silverlight 2 do I specify a Python file - either in
the 'createObjectEx' call or in the xaml file it loads...

I don't want to be dependent on Chiron for creating/deploying dynamic
language applications, and I certainly don't want to have to hand roll XML
manifest files. Hopefully this isn't necessary I just can't quite work it
out yet.

Subject: [IronPython] Silverlight 2 Controls
Message-ID: <47D3F118.8010409@voidspace.org.uk>

Hello all,

I'm adapting a Silverlight 2 controls example for IronPython. It is 
based on:

http://silverlight.net/Samples/2b1/SilverlightControls/run/default.html

It seems that the shiny new controls, like Button, ToggleButton, 
WatermarkedTextBox (etc) don't come 'out of the box' with Silverlight2. 
 From downloading this example I can see the example includes several 
dlls - presumably ones that *extend* System.Windows.Controls.

As a result XAML that uses elements like these throws parse errors with 
not-recognised elements. I have these dlls - how do I add them to my 
IronPython project? If I just add a reference to 
'System.Windows.Controls' will it use the new dlls?

Thanks

Michael

Hand rolling XML manifest files is really just create one and re-use it all over the place.  This is what it typically looks like:

<Deployment xmlns="http://schemas.microsoft.com/client/2007/deployment" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" RuntimeVersion="2.0.30226.00" EntryPointAssembly="Microsoft.Scripting.Silverlight" EntryPointType="Microsoft.Scripting.Silverlight.DynamicApplication">
  <Deployment.Parts>
    <!-- Add additional assemblies here -->
    <AssemblyPart Name="Microsoft.Scripting.Silverlight" Source="Microsoft.Scripting.Silverlight.dll" />
    <AssemblyPart Source="Microsoft.Scripting.dll" />
    <AssemblyPart Source="IronPython.dll" />
    <AssemblyPart Source="IronPython.Modules.dll" />
  </Deployment.Parts>
</Deployment>

Drop that in a .ZIP file w/ the python file and those DLLs and rename it .xap.  Unfortunately I don't believe there's a way to just deploy a .py file.  The current model is you have the manfiest which points at DynamicApplication and that in turn loads the language and subsequently the .py file.

Somehow the referred assemblies can be somewhere else as well but I'm not sure what that looks like.

This comes back to the manifest mentioned in the previous question.  You can update the manfiest to contain the additional assemblies which are included w/ the Silverlight SDK.  Those assemblies will get loaded allowing the XAML to parse.

Ok. I've been playing with manifest files and still can't use the extra 
controls. See separate email.

Can you confirm that (as far as you know) this means that *every* 
IronPython Silverlight application has to send the IronPython dlls. Plus 
if I want to make the standard library available (for a Python 
interactive interpreter for example) then I have to package the *whole* 
standard library in the 'xap' file?

This is instead of the previous model (fro Silverlight 1.1) where 
assemblies and Python files would only be fetched from the server if 
they were actually needed. If what I have just said is true then the new 
model is *massively* inferior in my opinion.

It is also ironic that Jim Hugunin and John Lam (in Mix 07) made much of 
how the great advantages of working with dynamic languages for 
Silverlight is that they can be deployed as text. Now of course they 
need to be 'compiled' with a custom tool (chiron) and deployed in this 
compiled form - and not deployed as text...

Feel free to pass my comments on to those who made these decisions (I'm 
well aware it isn't you Dino)... On the other hand I may be wrong (and 
would be both delighted and apologetic).

Importing I haven't actually tried, I've only used those controls from XAML.  But you might be able to do clr.AddReference once it's in your manifest and then be able to import.  If that works I think it's something we can probably make automatic.

If I add them to the manifest *and* add the following magic to the XAML 
then I can read them from XAML:


    
xmlns:c="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"
    
xmlns:e="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Extended"


I *really* do want to use these from code though. I tried both of the 
following forms to add references to the new assemblies:

import clr
clr.AddReference('System.Windows.Controls')
clr.AddReference('System.Windows.Controls.Extended')
from System.Windows.Controls import Button

import clr
clr.AddReference('System.Windows.Controls, Version=1.0.0.0, 
Culture=neutral, PublicKeyToken=null')
clr.AddReference('System.Windows.Controls.Extended, Version=1.0.0.0, 
Culture=neutral, PublicKeyToken=null')
from System.Windows.Controls import Button

Both raised the following exception:

IOException: Could not add reference to assembly System.Windows.Controls


Any further suggestions?

Hi all,
I've been experimenting recently with getting SCons to run using
IronPython. Unfortunately, it doesn't work yet. I've written up my
progress so far at
http://www.ironpython.info/index.php/SCons_on_IronPython. SCons is a
pretty tough workout, so getting it working would be good for
IronPython. If anyone's interested I can supply a patch, but it will
be pretty rough.

Subject: [IronPython] Silverlight 2 and app.xap layout
Message-ID: <47D488A3.1070906@voidspace.org.uk>

Hello all,

An issue with chiron and the directory layout you need to create an 
'app.xap'.

(Note - I am doing this on a machine without the SDK or Visual Studio 
installed so that I can test on a machine similar to the ones I will use 
the Silverlight apps from.)

In order for chiron to serve an application from the filesystem you need 
to create an
'app' subdirectory and place your Python files (etc) in this.

If you then run 'chiron /x:app.xap' on this folder it creates a zip file 
with the same directory structure - but Silverlight is then *unable* to 
use the resulting app.xap (it fails with a error message 'the 
application must have an entry point app.*' - it is unable to find 
app.py from the app subdirectory).

If you copy the files into a flat directory structure then chiron will 
generate an app.xap that Silverlight can use - but chiron is *unable* to 
serve the application from this folder *until* you
have generated app.xap.

This means that you cannot use the same folder layout for testing your 
apps and for creating them...

I was running into the same issue but you can specifically ask Chiron to zip the app folder by doing:
Chiron /d:app /z:app.xap. The /z switch adds the dlr assemblies as well. This xap runs from cassini.

	example)?
Message-ID: <47D4D087.4050301@yahoo.com>

Hi --

I'm trying to hook up IronPython to web services secured by Web Services 
Enhancements (WSE) 3.0. I have some C# sample code that I'm trying to 
convert to Python and am running into some trouble. I'm a C# and Windows 
..NET newbie (using IronPython from the commmandline), so the libraries 
in question are foreign to me, so I was hoping someone could help me 
resolve this. The sample code shows:

--------------------------
using Microsoft.Web.Services3;
using Microsoft.Web.Services3.Design;
using Microsoft.Web.Services3.Security;
using Microsoft.Web.Services3.Security.Tokens;
namespace TpIntegration
{
public class TpPolicy : Policy {
  public TpPolicy() {
    Assertions.Add(new UsernameOverTransportAssertion());
  }
  public static UsernameToken GetUsernameToken(string username, string 
password, PasswordOption passwordOption) {
    UsernameToken token = new UsernameToken(username, password, 
passwordOption);
    ISecurityTokenManager securityTokenManager =
    
SecurityTokenManager.GetSecurityTokenManagerByTokenType(WSTrust.TokenTypes.UsernameToken);
    securityTokenManager.CacheSecurityToken(token);
    return token;
  }
  public static void ApplyAutheticationTicket(WebServicesClientProtocol 
protocol, string userName, string password) {
    UsernameToken token = GetUsernameToken(userName, password, 
PasswordOption.SendPlainText);
    protocol.SetClientCredential(token);
    protocol.SetPolicy(new TpPolicy());
  }
}
}
--------------------------

This is then called using something like this:

--------------------------
UserServiceWse userService = new UserServiceWse();
TpPolicy.ApplyAutheticationTicket(userService, "admin", "admin");
--------------------------

I've taken a swing at converting it:

--------------------------
import Microsoft.Web.Services3
import Microsoft.Web.Services3.Design
import Microsoft.Web.Services3.Security
import Microsoft.Web.Services3.Security.Tokens

def getUsernameToken(username, password, passwordOption):
    token = 
Microsoft.Web.Services3.Security.Tokens.UsernameToken(username, 
password, passwordOption)
    securityTokenManager = 
Microsoft.Web.Services3.Security.Tokens.SecurityTokenManager.GetSecurityTokenManagerByTokenType(Microsoft.Web.Services3.Security.WSTrust.TokenTypes.UsernameToken)
    securityTokenManager.CacheSecurityToken(token)
    return token

def applyAutheticationTicket(protocol, userName, password):
    token = getUsernameToken(userName, password, 
Microsoft.Web.Services3.Security.Tokens.PasswordOption.SendPlainText)
    protocol.SetClientCredential(token)
    protocol.SetPolicy(TpPolicy())
--------------------------

but when calling it:

--------------------------
userService = 
WebService.Load('http://www.example.com/Services/UserService.asmx')
username = "test"
password = "test"
applyAutheticationTicket(userService, username, password)
--------------------------

I get the following error:

AttributeError: 'UserService' object has no attribute 'SetClientCredential'

Any suggestions on how to debug this further? In case it matters, this 
is code from 
http://www.targetprocess.com/download/tp20/TP_2_Web_Services_Guide.pdf.

Thanks!

Ramon

Looks like Webservice.Load is not returning a WebServicesClientProtocol. In the C# world you are instantiating a UserServiceWse. You could do the same in python so:
userService = UserServiceWse()

I assume the definition of that class would look like this:
def UserServiceWse(WebServicesClientProtocol):
        def __init__(self): #The constructor.
                self.blah = foo
                ...

    UsernameToken token = GetUsernameToken(userName, password,
PasswordOption.SendPlainText);
    protocol.SetClientCredential(token);
    protocol.SetPolicy(new TpPolicy());
  }
}
}
--------------------------

This is then called using something like this:

--------------------------
UserServiceWse userService = new UserServiceWse();
TpPolicy.ApplyAutheticationTicket(userService, "admin", "admin");
--------------------------

I've taken a swing at converting it:

--------------------------
import Microsoft.Web.Services3
import Microsoft.Web.Services3.Design
import Microsoft.Web.Services3.Security
import Microsoft.Web.Services3.Security.Tokens

def getUsernameToken(username, password, passwordOption):
    token =
Microsoft.Web.Services3.Security.Tokens.UsernameToken(username,
password, passwordOption)
    securityTokenManager =
Microsoft.Web.Services3.Security.Tokens.SecurityTokenManager.GetSecurityTokenManagerByTokenType(Microsoft.Web.Services3.Security.WSTrust.TokenTypes.UsernameToken)
    securityTokenManager.CacheSecurityToken(token)
    return token

def applyAutheticationTicket(protocol, userName, password):
    token = getUsernameToken(userName, password,
Microsoft.Web.Services3.Security.Tokens.PasswordOption.SendPlainText)
    protocol.SetClientCredential(token)
    protocol.SetPolicy(TpPolicy())
--------------------------

but when calling it:

--------------------------
userService =
WebService.Load('http://www.example.com/Services/UserService.asmx')
username = "test"
password = "test"
applyAutheticationTicket(userService, username, password)
--------------------------

I get the following error:

AttributeError: 'UserService' object has no attribute 'SetClientCredential'

Any suggestions on how to debug this further? In case it matters, this
is code from
http://www.targetprocess.com/download/tp20/TP_2_Web_Services_Guide.pdf.

Thanks!

Ah great. So in this case it is my fault! (And I'm just being a 
complainer...)

This is a horrible workaround but I think it should work.  You can create the object in XAML, then get the XAML and find the object, then call GetType().Assembly on it, and then pass that off to clr.AddReference.

I'll follow up with the Silverlight guys on our team to make sure we can do better.

clr.AddReference('System.Windows.Controls')
clr.AddReference('System.Windows.Controls.Extended')
from System.Windows.Controls import Button

import clr
clr.AddReference('System.Windows.Controls, Version=1.0.0.0,

clr.AddReference('System.Windows.Controls.Extended, Version=1.0.0.0,

from System.Windows.Controls import Button

Both raised the following exception:

IOException: Could not add reference to assembly System.Windows.Controls


Any further suggestions?

Two more possibilities which are little less ugly:
        1. AddReference to the fully qualified type name including strong name
        2. The bits at http://dynamicsilverlight.net/ - I'm told we should recognize the assemblies for you with some changes made there

I'm sorry to be dense - can you remind me how to get this strong name? I 
now have Visual Studio 2008 and the Silverlight tools installed.

I have success with using these shiny new controls from XAML *and* with 
the following code:


xaml = Application.Current.LoadRootVisual(Canvas(), "app.xaml")
something = xaml.FindName('watermark')

import clr
assembly = something.GetType().Assembly
clr.AddReference(assembly)
from System.Windows.Controls import Button

As you say, this is ugly and using the strong names would be better. :-)

That is what I'm using. If anyone has success with these binaries then 
let me know what you did!

sn -T System.Windows.Controls.dll gets you the public key token name...   But the only other way to get the entire thing is to put it in the GAC and do gacutil /l.  Alternately now that you've got the types in Silverlight you could display Type.AssemblyQualifiedName or Assembly.FullName.  It'd be the Silverlight strong name viewer app :).

I'm sorry to be dense - can you remind me how to get this strong name? I
now have Visual Studio 2008 and the Silverlight tools installed.

I have success with using these shiny new controls from XAML *and* with
the following code:


xaml = Application.Current.LoadRootVisual(Canvas(), "app.xaml")
something = xaml.FindName('watermark')

import clr
assembly = something.GetType().Assembly
clr.AddReference(assembly)
from System.Windows.Controls import Button

As you say, this is ugly and using the strong names would be better. :-)

That is what I'm using. If anyone has success with these binaries then
let me know what you did!

Just worked out the 'sn.exe' path myself. The following seems to work:


import clr
clr.AddReference('System.Windows.Controls, Version=1.0.0.0, 
Culture=neutral, PublicKeyToken=31bf3856ad364e35')


Great!!

Hi Srivatsn --

Thanks for the quick reply. I don't actually have UserServiceWse defined 
on the python side; I assumed that would be dynamically-generated from 
the WSDL call and that the appropriate methods would be found through 
introspectino. Is that incorrect? Is there some sort of stub-generator I 
need to run in order to auto-generate the UserService client class?

Well, if the WebService.Load method returned an object that this method then yes this should work. You can use wsdl.exe to generate the proxy in C# (or if u already have the code for UserServiceWse) then you can find out how the call is being made inside the UserServiceWse constructor and translate that to python.

Hi Srivatsn --

Thanks for the quick reply. I don't actually have UserServiceWse defined
on the python side; I assumed that would be dynamically-generated from
the WSDL call and that the appropriate methods would be found through
introspectino. Is that incorrect? Is there some sort of stub-generator I
need to run in order to auto-generate the UserService client class?

Got it -- that may be the problem. I generated the stubs as you 
suggested using WseWsdl3.exe (which I assume is the same as the tool you 
mention):

----------------------------------------
C:\Program Files\Microsoft WSE\v3.0\Tools>WseWsdl3.exe /type:webClient 
http://www.example.com/Services/UserService.asmx?wsdl
Web Services Enhancements 3.0 for Microsoft .NET.

Copyright (C) Microsoft Corporation. All rights reserved.
Writing file 'C:\Program Files\Microsoft WSE\v3.0\Tools\UserService.cs'.
----------------------------------------

The generated C# code does extend the right class:

----------------------------------------
public partial class UserService : 
Microsoft.Web.Services3.WebServicesClientProtocol {
----------------------------------------

but this code does not contain the SetClientCredential or SetPolicy 
methods, which is maybe not surprising giving the partial keyword.

I can't figure out how to do the equivalent in IronPython. If I check 
the type of the returned object, it is of type UserService, and I can't 
introspect it to find it's superclass. Am I correct in assuming that 
there is no equivalent to wsdl.exe for IronPython? I.e. there is no way 
I can use WebServicesHelpers to dump out Python code so I can inspect 
this more directly?

In the C# side you are using the constructor of UserService to create an instance of WebServicesClientProtocol. In the python side, you don't seem to be creating an instance of this. You can have a look at the constructor of the generated C# UserService and see how the instance is created and translate that to python. If you are having trouble with that post the constructor code here.

To load a XAML file and set the RootVisual, you can do this:

Application.Current.LoadRootVisual("file.xaml")

It's how we do it in the python samples on http://dynamicsilverlight.net

One problem is that XamlReader.Load takes the string of XAML and not a filename.  But there's something about the XAML that isn't working right too.  I'm no XAML expert but simplifying it to the code below works, you can probably build something up from that.  Personally for my Silverlight hacking I've just been building up the tree programmatically from Python code even though that's uncool :).

from System.Windows import Application
from System.Windows.Markup import XamlReader

Application.Current.RootVisual = XamlReader.Load("""
<Canvas Width="100" Height="100" xmlns="http://schemas.microsoft.com/client/2007"  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
        <TextBlock FontSize="30" Text="hello world"/>

Also installed is an extremely useful tool called Chiron which you'll find somewhere around C:\Program Files\Microsoft SDKs\Silverlight\v2.0\Tools\Chiron.  Chiron can take your .py file and produce a .xap which includes the IronPython & DLR DLLs using the /zipdlr command line option.  You can also use it to serve http requests and automatically serve up the .xap and let you just edit the files.



So once you're ready to make your xap the directory you point at should contain a .py file (I'm not sure what the multi .py file experience is like, but w/ a single file the it doesn't seem the name matters).    The simplest thing to put in there is:



from System.Windows import Application

from System.Windows.Markup import XamlReader



Application.Current.RootVisual = XamlReader.Load("someXaml")



You can see this from the Ruby perspective over at http://www.iunknown.com/2008/03/dynamic-silverl.html



There's various options on how to deploy the DLLs, and you can get into manifest files to deploy additional DLLs, but hopefully that'll get you started.

Suppose you don't want to load a XAML file - how do you do that (but say 
set a 'Canvas' instance you have created programatically) ?

That's just Application.Current.RootVisual = myCanvas

This is what I've been doing in my own Silverlight experiments, but I suck at using XAML and Blend :)

Yep, that's the way to do it =)

Ideally, this would be abstracted away in a silverlight.py utility module ... which I see as largely community driven ... so feel free to share anything you think would be great to reuse across all python Silverlight apps.

Cool - for some reason this didn't work for me the first time I tried it 
(I must have done something wrong). My minimal IronPython/Silverlight 
example is now a single Python file (app.py) containing:

from System.Windows import Application
from System.Windows.Controls import Canvas, TextBlock

canvas = Canvas()
textblock = TextBlock()
textblock.FontSize = 24
textblock.Text = 'Hello world from IronPython'
canvas.Children.Add(textblock)

Application.Current.RootVisual = canvas

Subject: [IronPython] compile bug
Message-ID: <47D7031B.7030207@voidspace.org.uk>

Hello guys,

There is a bug in the Python compile function relating to the
'PyCF_DONT_IMPLY_DEDENT' flag (which was added to support the standard
library 'code' module.


Python 2.5:

>>> compile('def f():\n    print "hi"\n\n', '<input>', 'single', 
PyCF_DONT_IMPLY_DEDENT)
<code object <module> at 011572F0, file "<input>", line 1>

IronPython 2a8
>>> compile('def f():\n    print "hi"\n\n', '<input>', 'single', 
PyCF_DONT_IMPLY_DEDENT)
  File "<input>", line 4

    ^
SyntaxError: invalid syntax

Unfortunately this prevents me implementing an interactive interpreter
in Silverlight 2 using code.InteractiveConsole. :-(

If there is *any* way this can be fixed in a version of dynamic 
silverlight then we can still have this for PyCon. ;-)

All the best,

Michael Foord

Hello guys,

Attempting to access the '__dict__' attribute of a SyntaxError exception
in IP2a8 *returns* an 'OperationFailed' object.

The codeop module (Python standard library) compiles source code and
*compares* the __dict__ attribute of SyntaxError exception instances...

(I can work around this bug for the interactive interpreter...)

Subject: [IronPython] No OpenReadCompleted Event for WebClient in
	Silverlight 2
Message-ID: <47D712F3.6060008@voidspace.org.uk>

Hello guys,

With the following code executed in Silverlight2 I find I get the 
'DownloadProgressChanged' event fired 3 times and the 
'OpenReadCompleted' not at all. :-(

The changed event shows 100% completed every time it is fired...

from System import Uri, UriKind
from System.Net import WebClient

uri = Uri('/', UriKind.Relative)
web = WebClient()

def completed(s, e):
    print 'Completed'
    print e.Error
    print e.Cancelled
    print e.Result

def changed(s, e):
    print 'Bytes Recieved', e.BytesReceived
    print 'Progress Percentage', e.ProgressPercentage

web.OpenReadCompleted += completed
web.DownloadProgressChanged += changed
web.DownloadStringAsync(uri)


Anyone got any clues?

Thanks

I'll take a look and get back to you.  Recompiling the dynamic silverlight bits might be a bit of a pain though (there's a bunch of internal process required to ship out binaries).

One option might be to use the Parser class directly but I don't know if that'll help you too much.

Unfortunately this prevents me implementing an interactive interpreter
in Silverlight 2 using code.InteractiveConsole. :-(

If there is *any* way this can be fixed in a version of dynamic
silverlight then we can still have this for PyCon. ;-)

All the best,

Interestingly it happens for any exception class with any property:

>>> BaseException().abc
<OperationFailed object at 0x000000000000002C>

This is somehow related to the new-style exception support for 2.5 compatibility.

Hello guys,

Attempting to access the '__dict__' attribute of a SyntaxError exception
in IP2a8 *returns* an 'OperationFailed' object.

The codeop module (Python standard library) compiles source code and
*compares* the __dict__ attribute of SyntaxError exception instances...

(I can work around this bug for the interactive interpreter...)

Well - if you can suggest some code. ;-)

Oh well.

Subject: [IronPython] Exception Handling in Silverlight 2
Message-ID: <47D72208.6080208@voidspace.org.uk>

Hello guys,

I'm seeing some oddness in exception handling in asynchronous callbacks 
(including handlers attached to HTML events).

If I have the following code for example which raises an exception in a 
'click handler' on a xaml animation:


canvas = XamlReader.Load(xaml)
storyboard = canvas.FindName('Example')
storyboard.AutoReverse = True

def OnClick(sender, event):
    storyboard.Begin()
    print 'before'
    x = None
    try:
        x = int('hi')
    except Exception, e:
        print 'oops', e
        x = 3
    print 'after', x
   
canvas.MouseLeftButtonDown += OnClick


When I click I see the 'before' and 'after' prints (I have diverted 
stdout) - but the exception handling code never seems to be executed.

You can have a look at the constructor of the generated C# UserService and see how the instance is created and translate that to python. If you are having trouble with that post the constructor code here.

I looked at the code for the DynamicWebServiceHelpers sample on codeplex and it doesn't seem to deal with WSE3.0. So I guess the proxy that is generated by WebService.Load will not derive from WebServicesClientProtocol but from whatever is the base class for the old web services(I think it's SOAPHttpClientProtocol). I guess you could do one of two things. Compile your generated proxy(UserService.cs) into a dll and then use that from python
Or port UserService.cs to python. You probably don't need the entire thing. My guess is that if u just set the url it might actually work - something like:
userService = WebServicesClientProtocol()
userService.Url = "http://www.example.com/Services/UserService.asmx"
TpPolicy.ApplyAutheticationTicket(userService, "admin", "admin")

Subject: [IronPython] InvalidProgramException testing hosting under NUnit
Message-ID: <8140eff40803120753s3d74b8afw4a8a15f55095d664@mail.gmail.com>

I have a small hosting class that works on a WinForms app. But it gives an
InvalidProgramException when called from a NUnit test.

The test project is within the IronPython solution and I've referenced
IronPython, IronPython.Modules and Microsoft.Scripting.

I'd like to know if other people were able to test hosting using NUnit.

Thanks.

There's an inner exception here (probably from Importer.cs in MakeImportSite) but there isn't much info on it.   Could you run it under a debugger and get that original stack trace?  It's not clear to me why we would blow up there.

Thanks for your help.

Sorry for some text in Portuguese below. I hope it doesn't get in the way.

The exception occurs within class ReflectionUtils, method CreateInstance<T>.

Line 127 is:
return (T)Activator.CreateInstance(actualType, args);

This in turns ends up calling the constructor public
PythonContext(ScriptDomainManager/*!*/ manager) in class
PythonContext.

Line 120 is:
_importer = new Importer(this);

A step into this line will cause the exception.

The stack trace of the innermost exception
([System.InvalidProgramException] = {"Common Language Runtime detectou
um programa inv?lido."}) is:

The correct thing to do is [to not follow the example in the
Silverlight docs, but instead] either use:

web = WebClient()
web.DownloadStringCompleted += completed
web.DownloadStringAsync(uri)

*or*

web = WebClient()
web.OpenReadCompleted += completed
web.OpenReadAsync(uri)

Depending on whether you want to fetch a server resource as a string
or as a stream. :-)

Subject: [IronPython] Access to CLR System namespace when python is executed
	inside C#
Message-ID: <dea2ab0e0803121418p3cc96ae9y4370073a5b4b085b@mail.gmail.com>

I am struggling to get IP to honor the System module when the IP is executed
inside C#. I am using Silverlight 2.0 Beta 1. I have the following code.

ScriptEnvironment.GetEnvironment().ExecuteSourceUnit(
PythonEngine.CurrentEngine.CreateScriptSourceFromString(@"
import clr
import System", SourceCodeKind.File)); <-- I've also tried
SourceCodeKind.Statements and SourceCodeKind.InteractiveCode

This code throws a "The method or operation is not implemented" exception.
It seems that any reference to System or any of its classes throws the
exception. I was hoping to have my custom assemblies executing in IP through
C# by now, and I can't even get the CLR assemblies to execute. Please Help!

What's likely happening is that you're getting a different ScriptEnvironment than the one which "normal" script code is running under.  You could get the current runtime by:

Microsoft.Scripting.Silverlight.DynamicApplication.Current.Environment

And then use that because it'll already have System.dll loaded.  Alternately you can add the references yourself:

ScriptEnvironment.GetEnvironment().LoadAssembly(typeof(string).Assembly);    // mscorlib
ScriptEnvironment.GetEnvironment().LoadAssembly(typeof(System.Diagnostics.Debug).Assembly); // System.dll

Nope, no such luck. Here's my test code:

--------------------------------
import clr
clr.AddReference("DynamicWebServiceHelpers.dll")
from DynamicWebServiceHelpers import *
clr.AddReference("Microsoft.Web.Services3.dll")

import Microsoft.Web.Services3.WebServicesClientProtocol
userService = Microsoft.Web.Services3.WebServicesClientProtocol()
userService.Url = "http://www.example.com/Services/UserService.asmx"
print "Done!"
--------------------------------

This produces the following exception:

--------------------------------
C:\IronPython-1.1.1\Samples\DynamicWebServiceHelpers\samples>ipy test.py

So I guess the proxy that is generated by WebService.Load will not derive from WebServicesClientProtocol but from whatever is the base class for the old web services(I think it's SOAPHttpClientProtocol). I guess you could do one of two things. Compile your generated proxy(UserService.cs) into a dll and then use that from python

You can have a look at the constructor of the generated C# UserService and see how the instance is created and translate that to python. If you are having trouble with that post the constructor code here.

Forgive the wide audience, there's not really a DLR mailing list...

I've been reading through Martin Maly's blog and I've enjoyed it, though I've noticed it glossed over one issue...how the ToyScript parser/lexer was created.  I've dug through the source of and they look hand written, as does the IronPython parser/lexer.  Are all of these hand written or is there some tool you use to write them?

Does anyone know of a good parser generator for .Net?  I've been wanting to play with the DLR some, but I don't want to pay the up-front price of writing a parser if I can help it.  I've seen MPLEX/MPPG, but they seem a bit under-documented.

Thanks,
-Lee

You might also take a look at Lex & Yacc.

On a related note: I was attending one of Martins talks in 2007 and remember
him saying that he created LOL-code script on a flight to Barcelona. So, I
think there must be some tools that can be used to do it. Check out his
LOLcode project and look for clues there.

F# [1] also has some kind of lex and yacc according to [2], I've never used
them myself, but being a .NET citizen one would think they should be able to
spit out something appropriate?

Message-ID: <0c216c7b-5481-469e-a954-39a0bd8ae7dc@m34g2000hsc.googlegroups.com>

Please excuse me if this is the wrong place to post this.  I am very
interested in how the DLR itself works.  I have not been able to find
a great deal about it though.  Perhaps I am not looking in the right
places.  I am trying to find out also if this is something I can learn
without going back to school because the only place that is doing this
kind of work is Microsoft and my experience with most schools is that
they are very anti-Microsoft so I would end up working on UNIX all the
time.  Not that I have anything against UNIX, I just like to have
other options.  Anyway (please excuse the tangent) I have purchased
used copies of several compiler and programming language texts (Aho,
Appel, Scott, Sebesta) off of Amazon as well as books about the CLR
(Gough, Box, Richter, Miller) to help me out.  That's my background.
Being already well-versed in Python and Ruby, I would like to see how
things work from the inside now.  Any pointers would be greatly
appreciated.

Thanks! :-)

Hmm. You don't really need C#, do you? Anyhow I'm not the expert, but do
check the Martins LOLcode script, which I mentioned.
http://www.iunknown.com/files/LolCode.zip

I mean, if it was done on a plane trip to Barcelna, he probably didn't hand
code all the parsing logic, I suppose.

There's a .NET version of Lex & Yacc from QUT, GPLex (http://plas.fit.qut.edu.au/gplex/) and GPPG (http://plas.fit.qut.edu.au/gppg/)

Microsoft licensed those tools and ship them as part of the VS SDK (announcement: http://blogs.msdn.com/somasegar/archive/2006/10/04/Next-step-in-VS-2005-SDK.aspx, VS SDK download available @ http://msdn2.microsoft.com/en-us/vsx/default.aspx)

As was mentioned in other responses on this thread, F# includes a version of lex and yacc (docs: http://research.microsoft.com/fsharp/manual/parsing.aspx)

If you like F#, but aren't a fan of Lex and Yacc, I highly recommend FParsec (http://www.quanttec.com/fparsec/) I've been playing with it but haven't had to a chance to write about it yet.

Other choices include ANTLR (http://www.antlr.org/), Irony (http://www.codeplex.com/irony) and Coco/R (http://www.ssw.uni-linz.ac.at/Coco/)

FYI, I recently wrote a series on my blog about parsing with F#. It doesn't use any of these libraries (I'm not a fan of lax/yacc & I hadn't discovered FParsec). It's just a parser (i.e. it doesn't generate any code) but it is a fairly complex grammar. http://devhawk.net/2007/12/10/Practical+Parsing+In+F.aspx

BTW, I'm the newest member of the Dynamic Languages team @ Microsoft (http://devhawk.net/2008/03/11/Joining+The+Dynamic+Languages+Team.aspx) and I'm currently in Chicago for PyCon. I'd love to get a chance to chat w/ anyone else attending from this list about Python and DLR,

Subject: [IronPython] DLR/ToyScript: Parser generator?

Forgive the wide audience, there's not really a DLR mailing list...

I've been reading through Martin Maly's blog and I've enjoyed it, though I've noticed it glossed over one issue...how the ToyScript parser/lexer was created.  I've dug through the source of and they look hand written, as does the IronPython parser/lexer.  Are all of these hand written or is there some tool you use to write them?

Does anyone know of a good parser generator for .Net?  I've been wanting to play with the DLR some, but I don't want to pay the up-front price of writing a parser if I can help it.  I've seen MPLEX/MPPG, but they seem a bit under-documented.

Thanks,

Well, the DLR is built on top of the CLR, so you might want to understand
the CLR first. There's lots of resources on the net about the CLR.

Subject: [IronPython] [IronPython 1.1] Scoping Advice(?)
Message-ID: <f7ea55b50803140037o3e14b8c1r50efac4feafd7142@mail.gmail.com>

Greetings everyone,

I've found this list an invaluable resource just by browsing past
conversations, however I was hoping to get a little advice and direction
with a question that I haven't really seen covered. (lately) I'm trying to
integrate IronPython into a live gaming server, which means opening it up to
people beyond my immediate circle of retribution should they do something
unpleasant.

What I'm looking for is some advice as to how to tighten the scope of a
module so that only the exposed hooks of my API are available. What I mean
to say is, those API hooks are already visible, what bothers me is that I
can type a couple of import statements into a script and do things like
inspect the file system and manipulate those files, etc. After poking at the
source I did something really inelegant, I made it so the parser did not
recognize the import keyword, but I can't help but think there has to be a
better way (as well as unseen consequences I haven't run into yet).

I could inspect every single script being submitted, and I do, however the
intent is to release the codebase for others to build their own worlds with.
The engine is friendly enough that non-hardcore coders can use it, and the
API is self-sufficient, which means that all an admin has to do is learn the
basic lexical structure of Python to really take advantage of it. Still, I
don't want a situation to arise where someone has a bad day and decides to
run a script that deletes all the files in the directory or something.

I'm not sure if I'm articulating myself correctly, it's late and I've spent
the last hour or so poring over the documentation to see if I could find
something. Any advice?

DLR CHANGES
The hosting APIs are nearing completion and will be unlikely to change much in future IronPython 2.0 releases.  For anyone interested, you might want to check out "EngineTest.cs" and "test_ipye.py" in the source zip file to get an idea of where the hosting APIs are for Beta 1.  It's also worth pointing out that the 'CodeBlock'/'CodeBlockInfo' AST symbols have been renamed to 'LambdaExpression' and 'LambdaInfo' respectively.  The APIs around both of these changed significantly since the last release.

ToyScript, a small scripting language built on top of the DLR, is merely a DLR sample and not some new scripting language Microsoft has created.  Also, ToyScript is not intended to be distributed with IronPython on a permanent basis.

I've developed a hosting helper class using IronPython and I would

previous email, I'm getting exceptions:

We are embarrassingly light on docs right now.  blogs.msdn.com/mmaly has a series of posts going through the ToyScript sample language and explaining mechanism used by language implementers on the DLR.  That would help you then to jump into the IPy sources from Codeplex.  blogs.msdn.com/Hugunin has some older posts with some overview material of the DLR.  http://compilerlab.members.winisp.net/dlr-spec-hosting.doc is the spec for how to host the DLR in your application, and a slightly outdated tour of using the APIs in a mock tool is at http://compilerlab.members.winisp.net/hosting-tour.doc.

Cheers,
Bill

Subject: [IronPython] DLR group?

Please excuse me if this is the wrong place to post this.  I am very
interested in how the DLR itself works.  I have not been able to find
a great deal about it though.  Perhaps I am not looking in the right
places.  I am trying to find out also if this is something I can learn
without going back to school because the only place that is doing this
kind of work is Microsoft and my experience with most schools is that
they are very anti-Microsoft so I would end up working on UNIX all the
time.  Not that I have anything against UNIX, I just like to have
other options.  Anyway (please excuse the tangent) I have purchased
used copies of several compiler and programming language texts (Aho,
Appel, Scott, Sebesta) off of Amazon as well as books about the CLR
(Gough, Box, Richter, Miller) to help me out.  That's my background.
Being already well-versed in Python and Ruby, I would like to see how
things work from the inside now.  Any pointers would be greatly
appreciated.

Thanks! :-)

Thanks Nick and Bill.  I have been looking into the CLR internals for
a while now.  I will take a look at the documentation links as well.
I assume that any of the classic compiler texts (Aho, Appel) would be
sufficient for taking apart the ToyScript language?  Or does the DLR
have a framework for interpreting built in?  I know the VS SDK has
tools like MPLEX and the DSL tools for languages.  Does the DLR have
something similar or is it worth a homegrown implementation?

Thanks! :-)

Classic compiler texts should be sufficient. DLR does not dictate you
to use any specific parsing technology. IronPython uses homegrown
lexer and parser, for example.

What you are describing is usually called "sandboxing", not "scoping".
Searching for "sandboxing Python" should give you some useful results.
Unfortunately, there is no simple and complete solution yet, as far as
I know.

Can you use .NET's application domain to isolate IronPython codes?

Hi Dino,

asked you about this at pycon. posting it here per our discussion to help
track it.
I understand it's not high on your priority list (and shouldn't be,
considering the other stuff there)

details:

have a python class (simplified here) that is a wrapper over an event:
class Future(object):
    def set(self,val) # set from one thread
    def get(self) # blocking until set. returns the value set.

I exposed the class to C# code through a template interface:
interface IFuture<T>
    void set(T val)
    T get()

the interaction in our case is that C# calls python, which returns a future,
which C# then waits on:
interface MyPythonSubsystem:
    IFuture<int> get_an_int()

Ideally I'd say that Future implements IFuture<T> for any T, by having
Future inherit from IFuture in python. I hoped this would mean IronPython
would accept my Future object when I returned it from the python
implementation of get_an_int().
Unfortunately, this isn't possible, and I could only inherit from IFuture[T]
for some specific T.

Ended up writing a simple function at the boundary between the subsystems
which gets T as an argument, and constructs an adapter that inherits from
IFuture<T> and proxies to an underlying Future object. It works fine for our
case, but less than pretty :-(

anyway, hope this helps document/track it
Ronnie

Subject: [IronPython] Unit testing IP hosting -- update
Message-ID: <8140eff40803170550j5834bedq60a5d509ea5825fa@mail.gmail.com>

I've sent some messages to this list about problems trying to use
NUnit to test IronPython hosting with IronPython-2.0A8.

Just so you know, with IronPython-2.0B1 that seems to be working, at
least with a very basic test.

Code follows.

Class1.cs
----------
using NUnit.Framework;

namespace UnitTest
{
    [TestFixture]
    public class Class1
    {
        [Test]
        public void TestHosting()
        {
            Host host = new Host();
            string x = host.Test();
            Assert.AreEqual("Hosting", x);
        }
    }
}


Host.cs
----------
using IronPython;
using IronPython.Modules;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;

namespace UnitTest
{
    public class Host
    {
        public string Test()
        {
            ScriptRuntime environment = ScriptRuntime.Create();
            ScriptEngine engine = environment.GetEngine("py");
            ScriptScope scope = environment.CreateScope();
            string scriptText = @"
def Test():
    return 'Hosting'
";
            ScriptSource script =
engine.CreateScriptSourceFromString(scriptText,
SourceCodeKind.Statements);
            CompiledCode compiledScript = script.Compile();
            compiledScript.Execute(scope);
            string functionCall = "Test()";
            ScriptSource function =
engine.CreateScriptSourceFromString(functionCall,
SourceCodeKind.Expression);
            return function.Execute(scope).ToString();
        }
    }
}

I'm guessing you missed Jim's talk otherwise you would have seen my demo :)

But anyway I'm still here - I'm down in Kitty Hawk working on making Django's latest and greatest work.  I'm here tomorrow too and leave Wednesday morning.

The short answer is yes, it runs.  The long answer is only 0.96.1 will run on IronPython 2.0 Beta 1 but there are some small issues:
1. You need a database provider (check out http://blogs.msdn.com/dinoviehland/archive/2008/03/17/ironpython-ms-sql-and-pep-249.aspx for my quick and dirty version of this).  The default DB providers don't run on IronPython because they rely on C extension modules.
2. There's a couple of fixes required to the SQL to run against MS SQL.  If you were to run against another DB this wouldn't be an issue.  The two tweaks I've made there are removing LIMIT 1 from one SQL call (by calling the backend function to generate limit syntax) and removing microseconds before sending off a DB query (same as MySQL).  Note this isn't an incompatibility between IronPython and CPython, just a DB difference.
3. Binary files from the static view don't successfully get downloaded.  This is due to a Unicode encoding issue (this is a simple 3 line fix of tracking the content type and only doing the encoding if necessary).  This is the only real incompatibility and is due to us not having ASCII strings - only Unicode.  This might not be an issue w/ a real web server though.  Also once Py3k comes out and both Django and IronPython update to it this issue will go away because the bytes type will be used instead of a string.
4. Along the lines of #3 I've only tried running the development server, there's no integration with a real DB server - this might be trivial to do though, I just haven't tried it yet.

I'm looking at the latest and greatest version from SVN now and there's a few issues there.  These are mostly known bugs but I'm fixing them as I encounter them:
               nt.access is missing
               traceback's don't get created when catching from the same function that throws
               ?, I'm stuck at the traceback issue right now :)

Once I get the latest and greatest running I want to start running through the test suite to see if any other issues are lurking.  Unfortunately we need doctest support for that which means we need sys.settrace, so there's some more work to be done.

Ahh, thanks for the answer. Quite a few issues to address I see. Do you
think it would make sense to run it in IIS somehow? (not via fastcgi with
CPython, but with IronPython). Is that even doable yet?

Since I am no python expert, but I am rather coming from a C background (and
nowdays C# :)), the PEP 249 code you've written isn't very clear to me. But,
I will stufy it at least and learn that way.

Are you also commiting to Django SVN the changes you make. or are you
running on your version?

It might be possible to fix the one language compat issue on our side.  And at least one of the 2 SQL issues is already fixed in the latest version of Django.  So I'm hoping we can get compatible w/o needing to change Django.

But currently I have the tweaks on my own version :(.

Message-ID: <ea89d0e50803171716s2454718fs2289bdc92df2eddc@mail.gmail.com>

Hi,
I'm trying to figure out how to create an instance of a Python type
(i.e. tuple and file) using the hosting interface (from C#). In older
versions there was PythonTuple.MakeTuple, for example, but that seems
to have disappeared. Now PythonTuple and PythonFile both require a
CodeContext, which I'm pretty sure is internal.

Is there a nice, easy way in 2.0B1 to create a tuple and convert a
Stream to a file-like object?

Thanks,
Jeff

MakeTuple has been moved into PythonOps as PythonOps.MakeTuple.  The reason for that change is that we now want the public surface area of the .NET Python types to match the public surface area Python types.

File is more of a problem...  Unfortunately files do need to be bound to a context (for multi-runtime support).  If there's enough demand for it we could provide a PythonEngine class which is compatible w/ 1.x and we could expose the file creation via that.  Until then probably the only way to do it right now is to call __builtin__.file through Python code (to which you can pass in a stream).  The ObjectOperations class should make that fairly easy (you can convert file to a delegate and then call it).

CodeContext isn't actually internal but it's also not available to you via the hosting APIs.  Basically the DLR APIs are split into hosting APIs and language APIs.  The hosting APIs provide a pretty interface as well as a remoting model and the language APIs provide a ton of functionality specific to language implementers.

That's actually what I thought when I was trying to sleep last night
:). It's certainly acceptable, and I'm not sure using Streams as files
will be all that common anyway, but it seems that it could hang off of
ScriptEngine (i.e. engine.MakeFile(Stream)). However, I don't know how
applicable that we be to other languages (it's been a while since I
used Ruby). If you can think of a place to put it, great; if not, I
won't lose any (more) sleep over it.

Aside: I like the new ObjectOperations class. It makes a lot of the
stuff I have to do for NWSGI much easier. All of the new hosting APIs
are very nice to work with.

Thanks for your help, Dino.

Subject: [IronPython] ScriptRuntime.Globals
Message-ID: <b1c6aabb0803181435j48491856i706be3f18b5fc45a@mail.gmail.com>

Hi,

I'm working my way through the DLR hosting spec.

And in the spec docs there is a distinction between 3 levels of hosting. Now
in the case of IronRuby I tried hosting it with level one hosting and all I
can get to work is executing ruby files.
Whatever i put in ScriptRuntime.Globals doesn't matter because it looks like
I can't get to it.

What is the function of ScriptRuntime.Globals ? How do I access it?
Why do ScriptScopes exist ? I saw that ScriptRuntime.Globals is a
ScriptScope, so I guess that's the default script scope.  From what I
understand from the DLR spec is that it should give you a context for
running a script with it's own variables etc. but globals are shared by the
entire runtime.

Is there somebody that can explain me what I'm not getting?

Cheers
Ivan

Globals is a place for hosts to put stuff that will be exposed in some language specific way.  I believe in Ruby the plan is to expose this as members that live in object.  In IronPython it gets exposed via import.  So if you put something into globals you should be able to do:

import foo

and get it back out.

The other ScriptScope?s that you can pass in get exposed in IronPython as module-level variables so they should be accessible to code by just referring to them directly.

Hi,
I'm trying to figure out how to set sys.executable when hosting
IronPython. As best I can tell, I need to call
PythonContext.SetHostVariables, but I can't figure out how to get an
appropriate PythonContext. This causes sys.executable to be None,
which messes up pydoc (specifically os.path.dirname(sys.executable)).

Does this involve delving deeper into the hosting APIs, or is this a
Level 2 scenario?

Message-ID: <ea89d0e50803181738i26485ad2w75e66f8eacdecdc@mail.gmail.com>

Hi,
One part of the WSGI spec calls for sys.exc_info to be passed to a
function, and if certain conditions are met, that exception is to be
re-raised. The example given in PEP 333 is:
raise exc_info[0],exc_info[1],exc_info[2]

Previously I used PythonOps.MakeException for this but as of 2.0B1
that requires a code context. Is there another way to do this? I could
create some Python code dynamically and execute it, but I'd prefer not
too.

Thanks,
Jeff

Evaling __builtins__ should work (or import __builtin__ and then eval that).

Hi Dino,

> Until then probably the only way to do it right now is to call __builtin__.file through Python code (to which you can pass in a stream).  The ObjectOperations class should make that fairly easy (you can convert file to a delegate and then call it).

I get the gist of this, but I can't figure out how to get a reference
to __builtins__.file to call. What's the easiest way to get one?

Thanks,
Jeff

Evaluate, not Execute :). Thanks, Dino.

The code, for anyone else who's interested, is:
private static object MakePythonFile(ScriptEngine engine,
System.IO.Stream stream)
{
    return engine.Operations.Call(
        engine.CreateScriptSourceFromString("__builtins__['file']")
        .Compile().Evaluate(engine.CreateScope()),
    stream);
}

Shameless plug: NWSGI (http://codeplex.com/NWSGI) will use IronPython
to run WSGI apps on IIS. It still needs a bit of work (and I'm still
in the process of updating it for B1) and a lot of documentation, but
it works for some simple cases.

If Dino can get Django working on IronPython, I'd be very interested
in trying it with NWSGI to really stess it.

Does this mean that we shouldn't be creating CodeContexts?  I'm using
the class "IronPython.Runtime.Operations.PythonTypeOps+TypeCaller" to
construct new objects from Python types.  This process requires a
CodeContext, which I'm currently building from scratch as needed.

(The same approach could be used with the PythonType
"IronPython.Runtime.Builtin.file" in order to build a Python file
object a little more efficiently.)

Under which python code will be have automatically generated wrappers
and that way they can called in C# more easily...
Can you pls provide some details on how the project is going ?

I've just gotten back from vacation and will resume work on the
project once I recover from the twin devils of "jet lag" and "the
backlog".  I can't make any specific promises about progress right
now, but I'm definitely committed to making some :).

It's on CodePlex at http://www.codeplex.com/coils.  Feel free to
provide feedback or sign up :).

The existing code works against 2.0A8; it will updated for 2.0B1 by
the end of the week.

In general you shouldn't need access to CodeContext for doing anything - unless you're writing an API which will be consumed by script code.  And the hosting APIs don't expose CodeContext instances so it can be challenging to get one without jumping through hoops.

Obviously there's a bunch of things people want to do that are Python specific and aren't covered by the DLR hosting APIs.  It'd be interesting to collect all of those things so that we can make sure we get all of the features that people want.

So far I think the interesting ones would include:
        file
        exception info
        module access (built-ins at least and possibly Python modules)
        type caller (which will actually going away, so no big deal there, but might be worth a discussion)

There's also some cleanup here for example creating ScriptScope's from the DLR doesn't give you a very usable Python module but we'll be fixing that.

Are there other things that jump out at people as missing?  Also, is there much interest in a 1.1 compatible hosting API or should we just expose this additional functionality?

Does this mean that we shouldn't be creating CodeContexts?  I'm using
the class "IronPython.Runtime.Operations.PythonTypeOps+TypeCaller" to
construct new objects from Python types.  This process requires a
CodeContext, which I'm currently building from scratch as needed.

(The same approach could be used with the PythonType
"IronPython.Runtime.Builtin.file" in order to build a Python file
object a little more efficiently.)

Message-ID: <ea89d0e50803191751u6ba24883jc99e036b17faebe@mail.gmail.com>

Hi all,
I've finally built a binary version of NWSGI, which is much easier to
use than building it from source. It also includes a very simple
"Hello, World!" app to get started.

I've tested with some simple Paste applications, and CherryPy *almost*
works; if you hack around the bugs that it exposes, you'll get a nice
503 error page. With news that Django works, I'll give that a spin
when all of the bits are available.

Right now, it works best with IIS7 - deployment is dead simple.
Stories about IIS6 would be appreciated, as I don't have access to it.

Any and all comments are very much appreciated.

- Jeff Hardy

Subject: [IronPython]  subprocess module
Message-ID: <ea89d0e50803191754s49a7cad4sd0f4f886227d4b12@mail.gmail.com>

Hi all,
Attached is a partial .NET implementation of the subprocess module.
There are currently a few limitations:

* Popen.communicate doesn't work
* Can't redirect stdin except for PIPE
* Can't redirect stderr to stdout (i.e. using stderr=subprocess.STDOUT)
* Can't redirect to a file descriptor
* univeral_newlines is not supported
* Command strings are flaky (lists work much better). Use shell=True
if using command strings.

Except for what's listed above, it passes most (about 2/3) of the
subprocess test cases.

The code is under the Ms-PL, except for list2cmdline which is under
the PSF license. I believe this is the correct way to do it (but
correct me if I'm wrong!).

Seo, what needs to be done to add this FePy?

Odd - doesn't work for me. Hopefully I'll get the 'web ide' up soon so 
that other people can poke it for me.

Yep, got it working too (attached). This is against the IronPython bits from http://dynamicsilverlight.net/get/.

However, I have reproduced what you're talking about in dlrconsole (http://dynamicsilverlight.net/see/dlrconsole), which uses the older ironpython bits shipped in the Silverlight SDK. If you type Michael's code in there, it prints "Starting" but the font size never changes (note: the "root" referenced in Michael's code is the same as "canvas" in dlrconsole, so simply do "root = canvas" before typing in the code ... and sorry that there's no copy/paste! I guess that should be fixed =P)

Michael, which set of bits are you using?

I'm actually using the binaries that Dino gave me - which if anything 
should be more up to date than the ones from dynamicsilverlight.net. 
Perhaps it is something to do with the environment as I was testing it 
in my 'webide' which is a fairly similar environment to the DLRConsole. 
I've just got into London and will try it as a standalone script when I 
get home.

Thanks for trying this for me - and great to meet you Harry.

Subject: [IronPython] IPCE: getting started
Message-ID: <40468.71.59.123.159.1206067402.squirrel@webmail.brynmawr.edu>

IPCE users,

Just getting started with IPCE and wondering about the current state of
things. I'm trying to get started with some Windows.Forms testing, and
wanted to use the most modern version which is stable. I'm using IPCE-r7
under Fedora 8. Here's my setup, followed by some issues:

$ mono --version
Mono JIT compiler version 1.2.5.1 (tarball)
Copyright (C) 2002-2007 Novell, Inc and Contributors. www.mono-project.com
        TLS:           __thread
        GC:            Included Boehm (with typed GC)
        SIGSEGV:       normal
        Architecture:  x86
        Disabled:      none
$ pwd
/home/dblank/fepy/IPCE/IronPython-2.0A7/Tutorial
$ mono ~/Desktop/IPCE-r7/ipy2/ipy.exe
IronPython console: IronPython 2.0A5 (2.0.11011.00) on .NET 2.0.50727.42

>>>

1) I can't seem to import random:

>>> import random

** ERROR **: file mini.c: line 3897 (mono_method_to_ir): assertion failed:
(!sig->has_type_parameters)
aborting...
Stacktrace:

  at IronPython.NewTypes.IronPython.Modules.Random_1.GetRule
(Microsoft.Scripting.Actions.DynamicAction,Microsoft.Scripting.CodeContext,object[])
<0xffffffff>
...

This works with IPCE-r7/ipy/ipy.exe. Do I need a more modern mono? Or is
there another issue?

2) I'd use 1.1, but it doesn't seem to load Windows.Forms:

$ mono ~/Desktop/IPCE-r7/ipy/ipy.exe

3. I tried to build from svn sources, but the build.sh looks unmaintained:
 a. it stopped due to missing ../website/license.html (I made one)
 b. python-irclib-0.4.6.tar.gz was missing (I downloaded it)

4. If there is a README (or a wiki) for IPCE I would read it... and even
contribute to it!

Any pointers appreciated!

Yes. You need Mono version at least 1.2.6 to run IronPython 2.x.

This works for me.

0. Build stuffs inside IPCE were not really for public consumptions. :(
a. Yes. You need to run "make" inside website directory.
b. The idea is that you run ./download.sh and then ./build.sh.

Seo et al,

Between upgrading to a later mono, and installing libgdiplus-devel I'm
completely working! We'll be keeping the following page up-to-date with
notes on IronPython:

http://wiki.roboteducation.org/IronPython

Feel free to make corrections, comments, or other remarks there. (I've
also tried to document the IPCE build process so that members of the
community can also build the community edition. Looks like it works.)

Thanks to all for making this available, and for the community-supported
version!

-Doug

Odd. I'm using the binaries from dynamicsilverlight. The following code 
works fine as a standalone example, but doesn't change the font size 
when run from inside my web ide ??? Odd.

from System import TimeSpan
from System.Windows import Application, Duration
from System.Windows.Controls import Canvas, TextBlock
from System.Windows.Media.Animation import (
    DoubleAnimation, Storyboard
)

root = Canvas()

Application.Current.RootVisual = root

t = TextBlock()
t.FontSize = 20
t.Text = 'Move the Mouse Over Me'
root.Children.Add(t)

sb = Storyboard()
duration = Duration(TimeSpan.FromSeconds(0.25))
a = DoubleAnimation()
a.Duration = duration
sb.Duration = duration
sb.AutoReverse = True
sb.Children.Add(a)

Storyboard.SetTarget(a, t)
Storyboard.SetTargetProperty(a, 'FontSize')
a.From = 20
a.To = 30

def anim(s, e):
    print 'Starting'
    sb.Begin()
   
t.MouseEnter += anim

root.Resources.Add(sb)

Subject: [IronPython] JScript Absent from Dynamic Silverlight
Message-ID: <47E40406.5010800@voidspace.org.uk>

Hello all,

The binaries from dynamicsilverlight.net don't include the JScript 
binaries(which are part of the Silverlight 2 SDK).

When I use Chiron to build apps that include the extended controls (!?) 
it fails because of the absence of the Microsoft.JScript.Runtime.dll. 
When I add this dll it succeeds but doesn't include the dll!

Any reason for not including those assemblies in dynamic silverlight?

No, just slow to move bits over there. I'm moving all the downloads to there as we speak ... it'll eventually just serve as a place to host the downloads from dynamicsilverlight.net.

Any other suggestions on what to use the codeplex project for?

JScript wasn't included in the dynamicsilverlight.net release since that release has sources and binaries. JScript will only be released as binaries, so we didn't include it this time around. However, it provides a really bad story for language interop, since the Silverlight SDK and dynamicsilverlight.net have different versions of the DLR.

We're planning on refreshing the dynamicsilverlight bits next week, and making an effort include JScript in there as well.

Creepy! The extended controls definitely shouldn't depend on Microsoft.JScript.Runtime.dll! Can you send me a repro of that? John(s), any idea what the hell is going on here?

I noticed that this still isn't fixed in 2.0b1, so I took another look at
socket.cs and realized that my analysis was slightly off.  There's already a
mechanism to track duplicated sockets in the form of the handleToSocket
mapping.  However, this mechanism isn't taken into account when deciding
whether or not to Close() the BCL Socket object.

Bottom line: I believe this bug can be fixed simply by moving the call to
_socket.Close() from socket.close into socket.RemoveHandleSocketMapping, and
only calling it when sockets.Count reaches zero.

Hello Jimmy,

(Sorry for calling you Harry yesterday...)

Download site and discussion forum for dynamic silverlight seems fine 
(although I prefer this mailing list for discussions)...

It just upset me to see it out of date. :-p

Jimmy is the best person to answer its status vs. silverlight.net.

I'm getting some more obscure oddness with Chiron - both under Windows 
and on the Mac. I'm not sure if it is reproducible though.

I'm currently still working on my articles and have to tackle this 
properly soon (probably tomorrow as it is now nearly 1am here).

I'll leave the results for another post with any repro instructions if 
they are consistent. I do wonder if there is some odd kind of caching 
going on inside Chiron?? (Some xap files don't get binaries added - some 
cause the browser to make additional requests for assemblies and some 
just don't work...)

Subject: [IronPython] DLR 2.0 Beta 1 can't hosting in another AppDomain
Message-ID: <tencent_3AB8111307FE1604230AB39F@qq.com>

Hi, 
  
 I have written a DLR hosting application, create ScriptRuntime in another AppDomain, DLR throw exception when execute code. the detail code like follow:
  
 public class ScriptProxy : MarshalByRefObject, IScriptProxy
{
    private ScriptEngine m_ScriptEngine;
    private ScriptRuntime m_ScriptRuntime;
     public ScriptProxy()
    {
        ScriptRuntimeSetup runtimeSetup = new ScriptRuntimeSetup(true);
        m_ScriptRuntime = ScriptRuntime.Create(runtimeSetup);
        m_ScriptRuntime.GlobalOptions.DebugMode = true;
        m_ScriptRuntime.GlobalOptions.DynamicStackTraceSupport = true;
         //Default script engine
        m_ScriptEngine = m_ScriptRuntime.GetEngine("python");
    }
}

//=======Client code as follow =====================

 private void Initialize()
{
    Evidence evidence = AppDomain.CurrentDomain.Evidence;
    AppDomainSetup appSetup = new AppDomainSetup();
    appSetup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory;
    m_ScriptAppDomain = AppDomain.CreateDomain("ScriptProxy", evidence, appSetup);
     m_ScriptAppDomain.Load("ScriptProxy");
    m_RemoteScript = (IScriptProxy)m_ScriptAppDomain.CreateInstanceAndUnwrap("ScriptProxy", "ZuHong.TestMore.Scripting.ScriptProxy");
}


 m_RemoteScript.ExecuteCode(txtScriptSource.Text);
  
 ==========================================
 DLR throw exception when execute code: SourceUnit not marked as SerializableAttribute.

Message-ID: <3ef6c057-b0b0-4348-af6f-b6513a44e9b3@i12g2000prf.googlegroups.com>

Hi,

I was reading the article on UI automation in MSDN (http://
msdn2.microsoft.com/en-us/magazine/cc163288.aspx) and decided to use
IronPython to control the example.

Unfortunately, I found that finding elements based on type doesn't
work. The example application has 1 button on the form. If I type the
following code I get an AutomationElement object:
form.FindFirst(TreeScope.Children,
PropertyCondition(AutomationElement.NameProperty, "Calculate"))

But with the following code, I get None returned:
form.FindFirst(TreeScope.Children,
PropertyCondition(AutomationElement.ControlTypeProperty,
ControlType.Button))

The C# code that accompanies the article successfully uses the FindAll
with AutomationElement.ControlTypeProperty. Is this a known issue in
IronPython? I'm using IronPython 1.1.1. Is this fixed in 2.0?

TIA,
-- Marcel

{ran_emo} Instead of posting my PyCon talk slides, I've turned them into a series of articles instead, which should be easier to follow. All the examples are available online and for download. This is everything you need to get started with IronPython and Silverlight 2. {sm;:-)}

All the articles, demos and downloads can be found at: `Voidspace IronPython and Silverlight Pages <http://www.voidspace.org.uk/ironpython/silverlight/index.shtml>`_.

You can experiment online with the `IronPython & Silverlight Web IDE <http://www.voidspace.org.uk/ironpython/webide/webide.html>`_.

There is also a prototype of my `Interactive Python Interpreter in the Browser <http://www.voidspace.org.uk/ironpython/silverlight/interactive.shtml>`_. Due to a bug in the *current* Dynamic Silverlight binaries it can't handle indented blocks. I expect Dino will be able to post fixed binaries soon. If you want to help me make the Javascript cross-browser then get in touch! (Currently it is safari only I think.)

    {title;The Articles}

These articles will take you through everything you need to know to write Silverlight applications with IronPython:

* `Introduction to IronPython & Silverlight 2 <http://www.voidspace.org.uk/ironpython/silverlight/introduction.shtml>`_
* `The Structure and Contents of a Dynamic Silverlight Application <http://www.voidspace.org.uk/ironpython/silverlight/silverlight_application.shtml>`_
* `Getting Started: Minimal Examples of IronPython and Silverlight <http://www.voidspace.org.uk/ironpython/silverlight/minimal.shtml>`_
* `The Silverlight APIs <http://www.voidspace.org.uk/ironpython/silverlight/silverlight_api.shtml>`_
    
    Exploring the Core-CLR that comes with Silverlight. This includes accessing the browser DOM, working with XAML, creating controls, the video player, accessing server resources, using local storage and more.

* `From Silverlight to Javascript and Back Again <http://www.voidspace.org.uk/ironpython/silverlight/scriptable.shtml>`_

    Interacting with Javascript from IronPython code is easy, but needs a bit of C#. This article shows you how to do it - including compiling the C# from the command line (without Visual Studio installed).
    
* `Embedding IronPython in a C# Silverlight Application <http://www.voidspace.org.uk/ironpython/silverlight/embedding_ironpython.shtml>`_

* `Interactive Python Interpreter in the Browser`_

    An interactive Python interpreter that runs in the browser, inside an HTML textarea. Great for documentation and tutorials where you can try the code in the browser.

I wonder if Chiron tried to reference the JScript binaries because the 
app directory had a '.js' file?

In either case I have completely failed to get Chiron to do 'the right 
thing' with creating my 'xap'
files and ended up building them by hand.

The pattern I used was to have 'Chiron.exe' (with all the assemblies etc 
that come from dynamicsilverlight.net which is the version I'm using) in 
a bin subdirectory. I was using it on Windows Vista and added the bin 
directory to the path. I would then invoke it in the following way:

    chiron /d:path/to/example/app /x:another/path/to/output

It would create 'xap' files, but not put the assemblies *or* a manifest 
in them. I gave up trying to use it.

UI Automation did have a problem with IronPython. See http://blogs.msdn.com/shrib/archive/2008/03/24/ironpython-cannot-call-automationelement-fromhandle.aspx. I am not sure if the issue has been fixed yet by the UI Automation team. Or if you are running into that same issue or something else.

Thanks,

A small remark:
+ d = dict(child.__class__.__dict__).copy()

Since you are already copying, I think copy method call would be
unnecessary. So:
+ d = dict(child.__class__.__dict__)

That'd be it! If you don't have a AppManifest.xaml file in your app, it'll
look at the extensions of all your script files to figure out which language
assemblies to include in the XAP. If you do have an AppManifest.xaml, it'll
just include the ones in there.

That's crappy, sorry! I'm writing a blog-post to detail all the *features*
of Chiron. Trust me, it's not as creepy as it seems.

So, /x is not the correct flag =) For python/ruby/jscript, you only need to
flags below "Dynamic Language Options" ... the other ones are only really
used by Visual Studio (don't ask =)).

The correct flag is /z[ipdlr]. If you run Chiron like this:

Chiron /d:path/to/example/app /z:another/path/to/output/app.xap

It will generate app.xap with the correct assembles and AppManifest.xaml in
it. That's great for 1-off xap generation. If you just want to work on an
app and don't want to xap every-time, just run Chiron in the app directory
like so:

Chiron /w

And it'll automatically xap a directory when you ask for <directory>.xap.

I thought the documentation in Chiron was good enough, but an accompanying
blog post would have prevented a ton of frustration, I'm sure. Sorry about
that again, and I'm get that blog post out asap.

So I was just doing it wrong. :-)

That sounds entirely plausible. I'd better update the tutorial with the 
correct usage pattern. Thanks Jimmy.

Would I be correct in assuming that it is _not_ currently the intent that
IronPython run "arbitrary" existing Python code? I am interested in making
use of the Natural Language Toolkit (NLTK), a huge Python 2.5 application,
in a .NET environment. Clearly, the most powerful approach would be to use
IronPython, but I'm guessing (and please correct me if I'm wrong) that
current limitations in the IronPython 2.0b1 implementation are likely to
present many challenges in running/porting arbitrary "legacy" Python apps.
My purpose in writing this is simply to find out whether I should even
bother attempting such a feat.

As I understand it, the goal of IronPython is to support the running of that
kind of application -- provided that it doesn't use any binary
extensions[1].  The NTLK webpage is a bit vague on that count, suggesting
that "some users may require" numpy and matplotlib.  If you're not one of
"those users", you should give it a try!

Of course, there's some chance that NLTK won't work correctly under 2.0b1;
your reports in that regard will help all of us by driving IronPython closer
to CPython compatibility.

Thanks for the info, Curt. Stupid of me - I didn't even stop to think about
the issue of binary extensions. I absolutely need numpy! I'll track
Ironclad's progress now that you've made me aware of it. Meanwhile, I'll
think about using Python.Net in the interim, and just try to "embed" NLTK
(GIL and all) in my C# app.

Subject: Re: [IronPython] Sanity Check re. Legacy Python Code

 

As I understand it, the goal of IronPython is to support the running of that
kind of application -- provided that it doesn't use any binary
extensions[1].  The NTLK webpage is a bit vague on that count, suggesting
that "some users may require" numpy and matplotlib.  If you're not one of
"those users", you should give it a try!

 

Of course, there's some chance that NLTK won't work correctly under 2.0b1;
your reports in that regard will help all of us by driving IronPython closer
to CPython compatibility.

If you can check if the failing API calls Assembly.GetCallingAssembly by placing a breakpoint in the debugger, that would be 99% confirmation that it is the same issue.

Alternatively, you could change the C# code to use Reflection.Emit to create a method which invokes the UI Automation API. If this fails, it is the same bug. The bug affects all dynamic code (IronPython source code gets compiled to Reflection.Emit on the fly).

I have pinged the UI Automation team to find out the status of the bug.

You could open a bug in the IronPython tracker. Given that its most likely not an IronPython issue, we may not be able to get to it in time to unblock you.

Subject: [IronPython] Question about serialization
Message-ID: <47E8F69A.5010205@iinet.net.au>

Hi,

I'm using IP as a scripting engine in a C# app. I have various Python 
classes that derive from a C# base class, and have there own additional 
data & functionality.

I would like to be able to serialize instances of the Python classes 
from the C# host for persistence across sessions. Using the standard 
BinaryFormatter with the Serializable attribute is not working - I get 
an error about the python class not being marked as serializable (the C# 
base class is marked as serializable though).

How can I serialize python objects from C#? Should I use reflection to 
roll my own serializer, or is there something in one of the lesser 
documented assemblies like Ops I should use?

I'm using IP 1.1.1 (but will move to 2.0 if that will help). Any 
pointers & advice greatly appreciated!

Thanks, Paul

Typically for serializing Python objects you would use pickle [1]. The 
'dumps' function returns a string (make sure you use the text protocol 
for IronPython).

You could then execute code inside the Python engine to serialize / 
deserialize objects. I've not tried this for instances that inherit from 
C# base classes - but it should work fine. :-)

Thanks Michael for the advice. Must appreciated. Unfortunately I hasn't 
worked out yet tho :(

I can use pickle from C# using Evaluate, or from within a Python class, 
on a "pure" Python object. However any attempt at pickling a python 
object that derives from a C# base result in an exception like this:
Cannot convert MyObject(<MyObject object at 0x000000000000002B>) to Int32

Exploring further, I came across Ops.GetDynamicType() and 
Ops.GetAttrsNames() which I thought might be helpful to get the 
attributes of an object and serialize it somehow (manually), but 
GetAttrNames requires an ICallerContext, and I can't see how to get one 
of those.

It seems that whilst serializing .NET classes is trivial, and 
serializing python classes is trivial, serializing something that 
touches both is proving quite difficult.

Any further suggestions gratefully received!

Thanks, Paul

This is likely to be a Mono bug, probably specific to Mac OS X.

Hi,

i am news to this list, so let me give a short introduction of myself.

My name is Bernd from Aachen in Germany (near the border to Netherlands and
Belgium) and I am working with python for some time now. In the moment i am
shifting some of my old python-scripts into ironpython because the "normal"
python will not be installed on our 64bit windows servers. Ironpython as a
Microsoft-product is more welcome in the eyes of our customer.

So my (first) question regarding copy of object-instances:

How can i use the copy-module-functionality in ipy? Is there something
comparable in DOT.NET? Are a modern way to copy instance-data instead of
references.

Thank you very much and kind regards.

Bernd

Have you tried just using the py files that ship with CPython?

You can get a distribution of IronPython that incorporates these files
from Seo's FePy project at http://fepy.sourceforge.net

This is an interesting problem. Python's pickle writes out enough data to
rebuild the object entirely -- including the class definition, if the object
is a user-defined type.  How do you accurately write out a class definition
for a C# base class?  Would you restrict it to strongly named classes?

Unfortunately I don't think what you want will work.  If it's your .NET class you could implement __reduce_ex__ and I think we'd pick it up and use that for the serialization.  But if it's some arbitrary framework class then you'll run into trouble.  On IronPython 2.0 you could have an extension class w/ the __reduce_ex__ function, have an ExtensionTypeAttribute that links the .NET base class and the extension class, and then call RuntimeHelpers.RegisterAssembly and we'd pick up the extension method.

Also, we do have a feature request for this on CodePlex: http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=13401  Voting on it would raise its priority and we'd be more likely to do it sooner rather than later.

Thanks Michael for the advice. Must appreciated. Unfortunately I hasn't worked out yet tho :(

I can use pickle from C# using Evaluate, or from within a Python class, on a "pure" Python object. However any attempt at pickling a python object that derives from a C# base result in an exception like this:
Cannot convert MyObject(<MyObject object at 0x000000000000002B>) to Int32

Exploring further, I came across Ops.GetDynamicType() and Ops.GetAttrsNames() which I thought might be helpful to get the attributes of an object and serialize it somehow (manually), but GetAttrNames requires an ICallerContext, and I can't see how to get one of those.

It seems that whilst serializing .NET classes is trivial, and serializing python classes is trivial, serializing something that touches both is proving quite difficult.

Any further suggestions gratefully received!

Thanks, Paul

My guess is you'd restrict it only to .NET objects which are marked as being serializable.  Then you'd ask the object to serialize it's self and then stuff that into the pickle stream along w/ the extra Python info.  That's probably include a type name which you'd just load and see what you got - much like how cPickle does an import and uses what it gets when it's loading a global.

Subject: Re: [IronPython] Question about serialization

This is an interesting problem. Python's pickle writes out enough data to rebuild the object entirely -- including the class definition, if the object is a user-defined type.  How do you accurately write out a class definition for a C# base class?  Would you restrict it to strongly named classes?

I was thinking that Python's lack of a global namespace for classes would be
a problem -- but of course it's not because you'd actually be looking in the
CLR namespace.  So you could just fail the deserialize if the CLR base class
doesn't already exist.

It would still be nice to be able to auto-load an assembly when the base
class is strongly-named.

I suggest using copy_reg to register .NET class to Python pickle mechanism.
See: http://docs.python.org/lib/module-copyreg.html

I actually implemented this back in the last year.

thanks, but I am not allowed to install FePy on the Production-Server. So I
need a solution with pure IronPython ;-).

Subject: [IronPython] DLR: ActionBinder and ParseSourceCode
Message-ID: <67b73e970803262323rec00f6cm13f99c36d6d4ced8@mail.gmail.com>

Hi,

I wonder if that's a bug or by design.

Expression returned by Ast.Action.Operator(Operators.NotEquals,
Ast.Null(), Ast.Null()) [which I believe is equivalent to null !=
null] evaluates to True, though False could be expected (overriding
MakeRule<T> for this special case does the trick).

Having returned LambdaExpression from LanguageContext.ParseSourceCode
which has return type of void, produces
"System.InvalidProgramException : Common Language Runtime detected an
invalid program", changing return type to object solves the problem.

Bernd,

AFAIK, you should try to get the CPython libraries installed with
IronPython, otherwise you're missing functionality that you can use. Many
of the CPython libraries are pure-Python, and can be used directly by
IronPython.

FePy also includes the CPython libraries, but that is independent of
Mono/.NET issues.

Thanks for the suggestion, unfortunately, again, no dice. It seems there 
is no way to serialize an IP object that derives from a .NET base class. 
Even though the base class is marked as serializable, I still get an 
error about the derived class not being marked as serializable when I 
use the fepy pickle.

I'd be interested to trying using the DLR hosting mechanism...does 
anybody know of any docs about upgrading from IP 1.x to IP 2 script hosting?

Thanks, Paul

The CPython standard library, most of which works with IronPython, is 
just a bunch of Python files - which you could justifiably argue are 
part of your application. (The ones that work are pure Python - i.e. 
pure IronPython.)

You cn just put them in a directory and then either point to that 
directory with the IRONPYTHONPATH environment variable, or add 
'sys.path.append(direcotry_name)' at the start of your application.

This will allow you to use modules like 'copy'.

We sort of have a similar problem with respect to IronPython tests - the tests we ship on CodePlex need to run without dependencies on standard CPython libraries.  What we did for the case of the 'copy' module was to reimplement the functionality needed in pure Python.  For example, a naive implementation of copy.deepcopy might look like the following:
def copy(y):
    if type(y)!=list:
            return y
    ret_val = list(y)
    return [deepcopy(x) for x in ret_val]

Hope that helps!

Have you tried just using the py files that ship with CPython?

You can get a distribution of IronPython that incorporates these files

If you replace 'deepcopy(x)' with 'copy(x)' below it should work:)

Message-ID: <d4e0938d0803271201m73d086e8i92aa7d5662a2b551@mail.gmail.com>

Hi all,
  I'm putting together a seminar at our local Code Camp for hosting the DLR
and integration with applications. The hosting spec pdf is great however I
do have (at least) one question that isn't explained very well in the doc.
How can I restrict what assemblies can be loaded by a ScriptScope? To
explain further: If I use the following code to load a py script file

            ScriptRuntime env = ScriptRuntime.Create();
            ScriptEngine eng = env.GetEngineByFileExtension( "py" );

            ScriptSource source = eng.CreateScriptSourceFromString(
form.Source, SourceCodeKind.File );

            source.Execute();

Where form.Source is a string containing this :

import sys

import clr
clr.AddReference("System.Windows.Forms")
clr.AddReference("System")
clr.AddReference("Microsoft.Xna.Framework")
clr.AddReference("Microsoft.Xna.Framework.Graphics")
clr.AddReference("Microsoft.Xna.Framework.Input")
clr.AddReference("Bnoerj.AI.Steering.Demo.Plugins.Ctf")

from Bnoerj.AI.Steering.Demo.Plugins.Ctf import CtfBase, Globals

class CtfPythonSeeker(CtfBase):

    def __init__(self):
        Reset()

    def Reset(self):
        Globals.Instance.Seeker = self

How can I prevent some references from being referenced, like "
Microsoft.Xna.Framework" but allow "Bnoerj.AI.Steering.Demo.Plugins.Ctf"?

Thanks in advance

There's no way to currently do this from the DLR and I suspect it's beyond the scope of both the DLR and IronPython.  What you might be able to do is create an AppDomain with limited permissions and therefore prevent the loading of assemblies at the lower level.  Once you've done that the DLR hosting APIs have support for loading them in a remote app domain.

The reason why we wouldn't do this directly is it's very hard to prevent access.  Once you can do import clr you can do:

clr.GetClrType(str).Assembly.System.Reflection.Assembly.Load(...)

and there's likely other ways to get around any walls we could put up (e.g. 'abc'.GetType().Assembly...  not to mention any othe APIs that could return types).

Thanks much for the answers. The own implementation of copy is the best
solution for me. It works.

But allow me one question regarding the usage of "standard" CPython modules.

Who can i use them when using the IronPython-Studio? Haven't found any
config-items inside yet.


Thank you and regards

 Bernd

Thanks much for the answers. The own implementation of copy is the best
solution for me. It works.

But allow me one question regarding the usage of "standard" CPython modules.

Who can i use them when using the IronPython-Studio? Haven't found any
config-items inside yet.


Thank you and regards

 Bernd

Bernd,
 
I played around with this a lot myself when I was using IPS.  The only
solution I could find was to add an import statement to the top of any
file in which I wanted to use that code.  The concept of building a
"reference" as in C# is not yet supported in IPS.
 
I seem to recall being told that if you need to, you can also add paths
to sys.path in order to add things that are not in standard Python
paths; however, I myself haven't done this as I think that IPS just adds
the regular Python paths that it finds.
 
Hope that helps,
 
Rocco

	We sort of have a similar problem with respect to IronPython
tests - the tests we ship on CodePlex need to run without dependencies
on standard CPython libraries.  What we did for the case of the 'copy'
module was to reimplement the functionality needed in pure Python.  For
example, a naive implementation of copy.deepcopy might look like the
following:

	def copy(y):

	    if type(y)!=list:

	            return y

	    ret_val = list(y)

	    return [deepcopy(x) for x in ret_val]

	 

	Hope that helps!

I was afraid of that. So, if I am reading your response correctly...

I can from my Apps AppDomain ( Primary ) create a second AppDomain (
Secondary ) which has limited permissions, specifically for me loading
assemblies. I can then use the DLR in the Secondary AppDomain and use the
DLR API to load the Assemblies I want.

That about sum it up. I know that there may be ways around it, I'm just
trying to be secure enough at this point.

Thanks,

Michael

Hi all,
  I'm putting together a seminar at our local Code Camp for hosting the DLR and integration with applications. The hosting spec pdf is great however I do have (at least) one question that isn't explained very well in the doc. How can I restrict what assemblies can be loaded by a ScriptScope? To explain further: If I use the following code to load a py script file

            ScriptRuntime env = ScriptRuntime.Create();
            ScriptEngine eng = env.GetEngineByFileExtension( "py" );

            ScriptSource source = eng.CreateScriptSourceFromString( form.Source, SourceCodeKind.File );

            source.Execute();

Where form.Source is a string containing this :

import sys

import clr
clr.AddReference("System.Windows.Forms")
clr.AddReference("System")
clr.AddReference("Microsoft.Xna.Framework")
clr.AddReference("Microsoft.Xna.Framework.Graphics")
clr.AddReference("Microsoft.Xna.Framework.Input")

I'd recommend "Customizing the Microsoft(r) .NET Framework Common Language Runtime" (http://www.microsoft.com/MSPress/books/6895.aspx ) for learning about the specific CLR knobs to twist in this scenario.

The script engine allows you to set the search path by calling
ScriptEngine.SetScriptSourceSearchPaths, but it neither lets you query the

Hello guys,

I'm trying to do some simple examples of hosting with IronPython 2. Boy 
you made things more complicated than IronPython 1. :-)

Unfortunately the DLR hosting spec document is out of date. I have a 
couple of questions (but will keep exploring).

The simplest use case is just to evaluate an expression and return a result.

The hosting spec document mention 'ScriptRuntime.Execute(text)'. This 
may or may not be the right way to evaluate an expression, but in any 
case it has been removed.

An alternative is:

    engine = PythonEngine.CurrentEngine # a ScriptEngine
    unit = engine.CreateSourceUnitFromString(code, id)
    result = unit.Execute()

Which is straightforward enough, however I can't see a way to set 
TrueDivision using this technique.  (What is the 'id' by the way?)

I can see that TrueDivision is a setting on 
IronPython.Runtime.ModuleOptions and IronPython.Runtime.PythonModule. 
Can I set this on the engine somehow?

All the alternative seem to lead down a rabbit warren of 'create this 
object - which requires this object - which you construct from another 
object - which...'. I don't know which path to follow down the rabbit 
hole...

:-)

Any suggestions to save me from madness?

Michael

Some of those look like names from A9, which have changed in B1.

The easiest way to evaluate an expression from scratch seems to be as
follows:

    ScriptEngine engine = ScriptRuntime.Create().GetEngine("py");
    ScriptScope scope = engine.CreateScope();
    ScriptSource source = engine.CreateScriptSourceFromString("1 + 1",
SourceCodeKind.Expression);
    int result = source.Execute<int>(scope);

I'm using B1. I expect they'll change in the next release though. *sigh* ;-)

In the old days a beta used to mean the API was fixed and it was only 
bugfixes that would go in... <0.5 wink>

Oops - didn't read all of your message. I'm using B1 and my code seems 
*pretty* similar except for the useful addition of SourceCodeKind - thanks.

heh

It seems to me that B1 is more consistent with the various published
DLR hosting specs than A9 was -- which suggests that the API churn for
the Microsoft.Scripting namespace is dying down.

Cool - I was just being rude.

Any ideas on switching on TrueDivision for the scope?

Hey, I feel your pain!  I'd swear that I've rewritten more hosting
code than I've written...

> Any ideas on switching on TrueDivision for the scope?

This is what I was able to puzzle out.  I have no idea how "correct" it is.
    ScriptSource source = engine.CreateScriptSourceFromString("import
foo", SourceCodeKind.Statements);
    ScriptScope scriptScope = runtime.ExecuteSourceUnit(source);
    Scope scope = scriptScope.GetVariable<Scope>("foo");
    PythonModule extension =
(PythonModule)scope.GetExtension(scope.Language.ContextId);
    extension.TrueDivision = true;

It looks like you can set this globally by doing something like this:
((IronPython.PythonEngineOptions)engine.Options).DivisionOptions =
IronPython.PythonDivisionOptions.New;

This worked!

Thanks - it is for a simple embedding example which is a calculator. The 
winforms UI builds up expressions and the '=' button evaluates them with 
the Python engine. :-)

Hello all,

I've written up the IP 2 hosting example (thanks Curt) at:

http://www.ironpython.info/index.php/Hosting_IronPython_2

I've created a couple of minimal C# projects for the ACCU talk next week 
and will post those online at some point.

Hi All,

IPY2.0 B1 Vista SP1

I keep seeing reference to 'Snippets' in IP Tracebacks on different
bits of code. Can't find anything on codeplex so assume it *probably*
something wrong this end.
I don't have a 'Snippets' module AFAIK.

Typical example
C:\Code\OSProjects>ipy wpf5.py
Traceback (most recent call last):
  File Snippets, line unknown, in Initialize
  File PresentationFramework, line unknown, in Load

Is it just me or.... :-)

The "snippets" represent executable code that's generated dynamically by the
DLR from your Python source.  Do you have a small piece of sample code that
reproduces the failure?

Subject: [IronPython] Multiple engines, multiple scopes
Message-ID: <d2155e360803291341x5318eef2pd6ed7561955b8705@mail.gmail.com>

Beta 1 now supports multiple engines inside the same AppDomain
provided that you create a ScriptRuntime for each:
    ScriptEngine engine1 = ScriptRuntime.Create().GetEngine("py");
    ScriptEngine engine2 = ScriptRuntime.Create().GetEngine("py");

A ScriptScope is loosely equivalent to a Python module.  Empty
ScriptScopes can be created from the engine:
    ScriptScope scope1 = engine1.CreateScope();
    ScriptScope scope2 = engine2.CreateScope();

So the ScriptScope is somewhat bound to the engine it was created
from.  But in actuality, the engine is only used for
ScriptScope.GetVariable<T>, and the other operations on ScriptScope
appear to be entirely independent of the ScriptEngine.

In particular, scope1.GetVariable<int>("foo") is equivalent to
engine1.GetVariable<int>(scope1, "foo").  But it appears to be quite
legal to say engine2.GetVariable<int>(scope1, "foo")
engine2.GetVariable<int>(scope1, "foo"), and the only difference
appears to be the context that's used for the type conversion -- if
needed.

Is this intentional?  It seems to me that it would be better if the
ScriptScope were either more tightly bound to the ScriptEngine or not
bound to it at all.

Subject: [IronPython] Creating Python classes in  IP2
Message-ID: <47EF6495.7070600@iinet.net.au>

Hi,

I'm attempting to update an application framework that uses IP1.1 to use 
IP2b1. In the framework, I create python objects that are derived from 
C# classes, so I can bind to an interface at compile time. I do this 
from C# by executing the .py file that defines the class, getting the 
class as a UserType from the module globals, and using Ops.Call to 
create an instance.

I've looked through the DLR hosting spec, and experimented a bit, but I 
can't see how to get the same thing working with DLR hosting. So, how do 
I create instances of python classes from C#?

Thanks, Paul

This works for me once I fix the mismatched XML tag (and the mail-induced
line breaks).  And when I don't, I get pretty explicit error messages as the
text of the exception:

SystemError: The 'DockPanel' start tag on line 4 does not match the end tag
of 'DockPanelTest'. Line 5, position 3.
-or-
SyntaxError: EOL while scanning single-quoted string
What was the exception that you were getting?

This is what works for me:

    ScriptRuntime runtime = ScriptRuntime.Create();
    ScriptEngine engine = runtime.GetEngine("py");

    // These next two lines are needed if you expect to be able to import System
    // without manually loading the assembly through Python
    // runtime.LoadAssembly(typeof(string).Assembly);
    // runtime.LoadAssembly(typeof(System.Diagnostics.Debug).Assembly);

    // File foo.py contains class Foo
    ScriptScope scope = runtime.ExecuteFile("foo.py");
    object theClass;
    scope.TryGetVariable("Foo", out theClass);
    object theValue = PythonCalls.Call(theClass);

Hi Curt,

Yeah the errors are pretty trivial to fix - usually XAML typos and the
.Net detail is fine to fix it. I was just a little confused about
Snippets in the traceback but no reference to my 'test.py' file.

A better example is the single line 'self.test' saved to to test2.py

python test2.py
C:\Code\OSProjects>python test2.py
Traceback (most recent call last):
  File "test2.py", line 1, in <module>
    self.test
NameError: name 'self' is not defined

ipy test2.py
C:\Code\OSProjects>ipy test2.py
Traceback (most recent call last):
  File Snippets, line unknown, in Initialize
NameError: name 'self' is not defined

Cpython does a bit better there in callstack detail :-)

I imagine this is just a temporary glitch in 2.0b1, as IronPython
1.1.1 shows the right line:

PS F:\IPCE-r7\ipy> .\ipy.exe test2.py
Traceback (most recent call last):
  File F:\IPCE-r7\ipy\test2.py, line 1, in Initialize
NameError: name 'self' not defined

Subject: [IronPython] Mixing Languages with the DLR
Message-ID: <47EFB105.3020004@voidspace.org.uk>

Hello all,

A quick question on mixing languages with the DLR. If we have an 
execution scope that we have executed code in - can we execute code from 
another language in the same scope?

If this is trivially easy (just use a different engine to execute the 
code in the same scope) then we could make Resolver One scriptable in 
the DLR language of your choosing... (Why anyone would want to use 
anything other than Python I don't know).

I know this works between Jscript and Python. Ruby doesn't yet play by the rules for method lookup. Fire up dlrconsole and see for yourself:

http://dynamicsilverlight.net/see/dlrconsole

js> function foo() {
js|   return 42
js| }
py> a = foo()
py> a
42.0
js> a
42.0

How it works? I believe it's something to do with sharing scopes, but you can take a look @ http://dynamicsilverlight.net/see/dlrconsole.zip. Everything is in /app/app.py

John, any idea when Ruby will play nicely with other languages?

Subject: [IronPython] IronPython 2 Exception Handling from C#
Message-ID: <47F0C8F5.1010601@resolversystems.com>

Hello guys,

I'm being lazy. Can anyone help translate the following IronPython 1 
hosting code to the IP 2b1 API nearest equivalent. (I have already 
translated the code to execute the file - it is the exception handling 
code I need help with):

            try
            {
                engine.Sys.argv = List.Make(args);
                ScriptSource source = 
engine.CreateScriptSourceFromFile(Path.Combine(rootDir, (string)args[0]);
                source.Execute();
            }
            catch (PythonSystemExitException e)
            {
                object o;
                return e.GetExitCode(out o);
            }
            catch (Exception e)
            {
                Console.Write(engine.FormatException(e));
                return 1;
            }
            finally
            {
                PythonEngine.DumpDebugInfo();
            }
            return 0;

Thanks (in advance...)

Michael

Subject: [IronPython] More IP2 Equivalents - setting argv and search path
Message-ID: <47F0D024.2070307@resolversystems.com>

Hello all,

I'm searching for more IronPython 2 equivalents and wondering if anyone 
on list knows. :-)

With IronPython 1 we would set 'sys.argv' with:

    engine.Sys.argv = List.Make(args);

(I think List here is the PythonList.)

We would also add paths to sys.path for an engine with:

    engine.AddToPath(path);

I'm currently doing this by generating strings of 'sys.path.append(...)' 
and executing the code which is a bit clumsy. :-)

I saw a post on the list recently about 
"ScriptEngine.SetScriptSourceSearchPaths", but this doesn't seem to 
exist in 2b1.

Thanks

Michael

Subject: [IronPython] Semi-blocking bug in IP 2B1
Message-ID: <47F0FED1.3020007@resolversystems.com>

Hello all,

There is a bug in dictionaries in IronPython 2 beta 1. I found this 
trying to port Resolver One to IP 2. Whilst I can work round it in this 
case I wonder how many times this bug will bite us in our code base:

 >>> d = dict()
 >>> d[0, 0] = 3
 >>> del d[0, 0]
Traceback (most recent call last):
  File , line unknown, in Initialize##345
TypeError: __delitem__() takes exactly 1 argument (2 given)

In general, error reporting/tracebacks seem to be much worse in 
IronPython 2. If I have time I will try and produce a repro...

Michael

If you run with a -D flag, you get much better error reporting.  This
is equivalent to setting (ScriptRuntime).GlobalOptions.DebugMode =
true in a hosting scenario.

(Thanks to Jimmy Schementi's post on the IronRuby list for pointing me at this.)

                                inst = (T)attr_type.CreateInstance(context);
                                break;
                            }
                        }
                    }
                }


Is there a way that is more portable between the different languages?

Exactly, it's beta 1 - therefore the idea is that the API is basically fixed and we should see mostly bug fixes and tuning from here on out.

It's not beta 2 yet! :)

I think TrueDivision is another reason for us to expose a Python specific hosting API (yeah, I realize that conflicts with what I just said somewhat...).

Cool - I was just being rude.

Any ideas on switching on TrueDivision for the scope?

Ok - and thanks. But we generate and execute code at runtime and need 
good error reporting for our users. If there is a performance 
implication we wouldn't want to have to set this flag just to be able to 
give our users useful tracebacks! The IP traceback handling is generally 
fine for us - but I haven't *confirmed* that IP 2 is worse - it just 
feels worse...

We have bigger problems anyway. Now I have ironed out the obvious 
problems, Resolver One runs on IP 2 but the user interface is completely 
broken. That is all pure-Python code so I have some digging to do... :-)

It looks like the DLR doesn't try to abstract "classness".  And given
that the semantics of a "class" vary so much between Python, Ruby and
Javascript, this isn't really a surprise.

It's actually something that's on our radar - it feels worse to me too.  It's something I plan on taking a look at before 2.0 final ships.

The more general DLR hosting API is much less suitable for Resolver One 
of course and a Python specific API would be very nice. If I get far 
enough I will try and post a bunch of questions about what is the *best* 
way of doing various things that we do with engines/scopes (beyond the 
questions I have already sent...). :-)

Thanks

I've created a bug for this - http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=15882

Given that it's a pretty bad regression I'll take a look at it after I finish up the work I'm doing on startup perf right now.

Subject: [IronPython] Semi-blocking bug in IP 2B1

Hello all,

There is a bug in dictionaries in IronPython 2 beta 1. I found this
trying to port Resolver One to IP 2. Whilst I can work round it in this
case I wonder how many times this bug will bite us in our code base:

 >>> d = dict()
 >>> d[0, 0] = 3
 >>> del d[0, 0]
Traceback (most recent call last):
  File , line unknown, in Initialize##345
TypeError: __delitem__() takes exactly 1 argument (2 given)

In general, error reporting/tracebacks seem to be much worse in
IronPython 2. If I have time I will try and produce a repro...

Michael

LambdaCompiler.Statements.cs basically says "if (Options.DebugMode &&
Options.DynamicStackTraceSupport) EmitGetCurrentLine()".  Maybe this should
be "or" instead of "and"?

There's actually a bunch of issues tangled together here but you're right, changing that statement would make the frames more usable...  There's actually some thoughts that our dynamic stack trace support should be pulled up entirely into IronPython and that might just happen.

The other issues are just related to how we generally produce frames.  For example if you do:

try:
                raise ZeroDivisionError
except:
                # start extracting frames from sys.exc_info()

In CPython you get a bunch of frames from above the except block and in IronPython you get no frames.  Turns out the inspect module does this and the latest Django in source control relies on that working :).

So to fix that bug requires that we always take a full stack trace when we get the frames.  And that of course kills exception handling perf in a quite significant way (it gets 3x more expensive to throw an exception, and it's already really expensive).   So we should bring this back w/o having the -D flag enabled, and we might also want to change how we track frames in general to do something better and more consistent w/ CPython.  But we can't push that down into the DLR so there's a non-trivial amount of work here.

Ok - and thanks. But we generate and execute code at runtime and need
good error reporting for our users. If there is a performance
implication we wouldn't want to have to set this flag just to be able to
give our users useful tracebacks! The IP traceback handling is generally
fine for us - but I haven't *confirmed* that IP 2 is worse - it just
feels worse...

We have bigger problems anyway. Now I have ironed out the obvious
problems, Resolver One runs on IP 2 but the user interface is completely
broken. That is all pure-Python code so I have some digging to do... :-)

Ok - something for us to watch. Allowing users to script Resolver One 
spreadsheets with Ruby could be fun.
