Is there any comparison between DLR and ParrotVM somewhere on the interwebs?

To my knowledge there is not a working python implementation under parrot
nor is there an IronPerl implementation for the DLR.  The comparison you ask
for is not even apples and oranges,  More like mushrooms and turnips :)

ParrotVM has a Python implementation ... though it's not a full implementation today (http://pirate.tangentcode.com/). Parrot seems to have a ton of language implementations build using it, but very few are complete implementations (with the exception of Perl); they are just tests of Parrot as a compiler infrastructure. The DLR has two fairly-complete language implementations (IronRuby and IronPython), along with some other test languages, that may or may not be available against the latest source code (JavaScript and Visual Basic existed against an older version, Scheme and Lisp are among the available ones today).

However, regardless of whether similar languages are implemented on those frameworks, you can still make comparisons between the DLR and Parrot as dynamic language compiler tools.

At a very high level, Parrot provides tools for the whole language development process, from a grammar engine, compiler tools, and a VM to run the generated code on. The DLR provides a way to get from a syntax tree to CLI code; it does not provide (or lock you into using) a specific parser to map your language to DLR syntax trees, and it uses any CLI-compatible VM to run on (CLR or Mono). The DLR also provides mechanisms to cache dynamic method calls, and make your language interoperate with existing CLI code.

For grammar engine, language development process, etc, there are a bunch of
efforts notably the M language, albeit far more ambitious than just a
language toolkit.

Both are providing facilities for interoperability between dynamic languages
(e.g. calling Python libraries from Perl)

Both are targeted as platform for dynamic language implementations.

Parrot VM has Perl6, a swiss army of a language that supports multitudes of
programming styles, etc. The closest in .Net stack is C# 4.0. Btw, does C#
4.0 dynamic qualify the language as a DLR language? I mean it is possible to
go dynamic crazy just with that keyword in C#.

Lets try this a second time :)

Thanks for the link.  I did not know about pynie.  And if you don't know
about it already, its effectively invisible for a google search of
"python+parrot+vm".

Parrot.org only links to pirate (which the nightly build shows 14 failed
tests and 47 errors out of 62 written tests and the last activity in the CVS
being ~ 3 years ago)

The strength of Ironpython is IMHO, the ability to tap into the .NET
framework.  As a reformed perl hacker, that is more important to me than
having python code that can use CPAN modules.

Ok, I've finally got SQL server setup in a reasonable state where I can try and repro this.  This is what I'm trying to do.  I have a database called "mydatabase" which contains a table "Table_1" which contains 1 column of type binary(4).  I then attempt to do:

import System
conn = System.Activator.CreateInstance(System.Type.GetTypeFromProgID("ADODB.Connection"))
connstr = "driver={SQL Server};Server=localhost;Database=mydatabase;Initial Catalog=mydatabase;Trusted_Connection=True;"
conn.ConnectionString = connstr
conn.Open()

rs = System.Activator.CreateInstance(System.Type.GetTypeFromProgID("ADODB.RecordSet"))
rs.Open("Table_2", conn, 1, 2, 2)  # source, active connection, cursor type (adOpenKeyset), lock type (adLockPessimistic), CommmandType (adCmdTable)
rs.AddNew()
b = System.Array[System.Byte]((2,3,4,5))
x = rs['Test1']
x.AppendChunk(b)

which fails with:

EnvironmentError: System.Runtime.InteropServices.COMException (0x800A0C93): Operation is not allowed in this context.

This is the same failure I get if I use Shri's proposed work around.  Do you have any idea of what I'm doing wrong or any suggestions on how to tweak this to get the correct simple repro?

Guys:
  Good work on the new release, and the 215 bug fixes. As usual, as soon as the new beta was announced I downloaded and tested it.

Somehow I got the idea that the adodbapi test had been included in the IronPython test suite. Did you only include the tests that already pass?  Issue 18222 is still unfixed -- so adodbapi still fails, and you still cannot pass a read-only buffer as a COM parameter.

I realize that no one has voted up this rather obscure bug. Perhaps if it were titled "fully support DB API 2.0 compliant database access using ADO" it would have gotten more votes. Nevertheless, this issue has been outstanding for 11 months, and is the only remaining failure in adodbapi for versions 2.3 thru 3.1 of python. Please try to get to it before 2.6 final.

Please !!!???

Vernon Cole

P.S. -- I plan to make a version of adodbapi which uses real ADO.NET<http://ADO.NET>, rather than ADO via COM, but I want the current version to be solid before I start mucking it up.

Any thoughts on this?  I can trivial add a DllImport to dlopen but
I need to know where it's declared :)

I'm not sure if there is standard library that this is implemented on
all *NIX platforms. It is possibly different.

No. dlopen and friends are POSIX standard.

I believe "libc" is the right one. From what I can tell, Mono maps
DllImport("libc") to whatever real C library file for the target
platform (this filename differs between Linux and Mac, etc).

Oops, no. Although "libc" is mapped as I said, dlopen and friends are
not in the C library, it seems. :(

I knew that dlopen was POSIX standard, what I meant was that I didn't
know if there was a standard shared library location (libc, etc) that
it was contained in.

Wow.  I completely missed it.  And someday I'll learn to read closely.  My
snarky comments deserved some snide.

I?ve noticed that with the latest bits for IronPython for ASP.Net<http://ASP.Net>, files in app_script only seem to be revisited when the app pool is restarted.



For example, if I have a file called hello_world.py in App_Script, and delete that file, the app still executes code in that file as if it were there. If I change a line in the file, that line is not shown as changed until I restart the app pool.



Is this by design, a bug, or something I?m doing wrong?

The refresh was unusable because it contained the version of IronPyton that is not compatible with .Net 3.5 framework (I think it was built on IP 2.0 Beta 3/4);

I'm griping about this issue in this list because I don't think this is a completely separate issue from the DLR programming languages. Maybe it is not a direct responsibility of this team, but the impact is direct for the following reasons:

  *   Nobody adopts a language as is. The libraries matters. The existing community of Python and Ruby are not going to move to Windows platform just because IronPython and IronRuby are being worked on and released. They have had a multi platform runtimes with de facto standards that are capable of doing wonderful things for more than a decade.
  *   There is much bigger market for language adoption for existing .Net/Windows based developers (and new developers) and these guys/gals are using mostly standard Microsoft stacks. And they are using .Net via mainly C# and VB.Net<http://VB.Net>. If the DLR languages do not have proper support at least for the major technology stacks (I would consider ASP.Net/Silverlight<http://ASP.Net/Silverlight> as major stacks), many people will not consider using the DLR based language for their production systems.
  *   I know ASP.Net<http://ASP.Net> MVC is open source and it's free to be extended etc, but ASP.Net<http://ASP.Net> WebForm have be en deployed massively and that's not going to change anytime soon. And theres is already a support, albeit poor and not up to date, for ASP.Net<http://ASP.Net> webform stacks in IronPython. Not having it fully updated is a waste of opportunity.
  *   .Net 4.0 and C# vNext contains dynamic language support but really, what is good for if the DLR languages can only be used in much more limited scenarios because some major technology stacks are not supported.
  *   You raised correctly that Django and  RoR are being used to validate the  languages. But I would argue that the existing technology stack support validates the DLR platform, not just the languages.

So yes, I'm not happy with the level of investment being put on supporting the technology stacks because I think it is pretty short sighted. No, I don't blame this team for this but at least if I complain on this list, it might have a chance being forwarded internally because this is one of the best community mailing list for Microsoft technologies.

Is there any update for IronPython for ASP.Net<http://ASP.Net>?



It has been three years since IronPython support for ASP.Net<http://ASP.Net> introduced with the release of the whitepaper (<http://www.asp.net/DynamicLanguages/whitepaper/>http://www.asp.net/DynamicLanguages/whitepaper/) and the first binary. Since then I think we've had Katrina, a Beijing Olympic, a new President, a financial collapse and two James Bond movies - yet until now there is still no up to date support for the technology. I know that the legal team, etc are working on the source release, but I think it is pretty galling that Microsoft's own web framework stack is barely supported by its own dynamic language technology, both on the 'classic' ASP.Net<http://ASP.Net> and MVC stack. I mean there is more energy put into having IronPython and IronRuby to run Django and RubyOnRails web framework instead of ASP.Net<http://ASP.Net> stack. This just doesn't make sense to me.

Hi all and many thanks to Dino Viehland for answering my previous
question re: sys.builtin_module_names and embedding.

I am trying to use the IronPython profiler (
http://blogs.msdn.com/curth/archive/2009/03/29/an-ironpython-profiler.aspx)
from an embedded interpreter but cannot figure out how to pass the

You have to pass the required options to Python.CreateEngine, like so:

var options = new Dictionary<string, object>();
options["EnableProfiler"] = ScriptingRuntimeHelpers.True;
ver engine = Python.CreateEngine(options);

Hope this helps,

Hi all and many thanks to Dino Viehland for answering my previous question re: sys.builtin_module_names and embedding.

I am trying to use the IronPython profiler (http://blogs.msdn.com/curth/archive/2009/03/29/an-ironpython-profiler.aspx) from an embedded interpreter but cannot figure out how to pass the -X:EnableProfiler to my ScriptEngine instance.

    _engine = Python.CreateEngine();
    Debug.WriteLine(_engine.Runtime.Setup.HostArguments.IsReadOnly);
    // prints True

    _engine.Runtime.Setup.HostArguments.Add("-X:EnableProfiler")
    // throws an System.NotSupportedException

Subject: [IronPython] DataBinding from IronPython Object to WPF Property
In-Reply-To: <10393772.61249502300406.JavaMail.SYSTEM@PCDaveR2007>
Message-ID: <20703168.81249502683593.JavaMail.SYSTEM@PCDaveR2007>

Hello,

I'm working with IronPython 2.6 Beta 1.

I have the following Python class:

class Person(object):
    def __init__(self, name):
        self.name = name

I'd like to be able to bind the name property of an instance of this class to a WPF textbox control.

I can do this easily enough either in XAML or in code. When the application starts, the textbox displays the person's name as expected.

However, if I make changes to the name, say, in response to a button click:

def button_click(sender, args):
    a_person.name += ", jr."

I don't see these changes reflected in the textbox.

I can make this work by calling UpdateTarget on the binding expression explicitly:

    exp = BindingOperations.GetBindingExpression(textbox, TextBox.TextProperty)
    exp.UpdateTarget()

but I had thought this would work without the explicit step, since it appears that IronPython supports INotifyPropertyChange.

Two questions:

(1) Is it possible to get databinding to work this way without having to explicity UpdateTarget?


(2) Say instead of the click handler above, we had:

def button_click(sender, args):
    global a_person
    a_person = Person("Fred")

In this case, the textbox remains bound to the first Person (which is no longer accessible from Python). Is there any way to get the binding to re-sync to the new object, short of setting a completely new binding to Person("Fred") in code?


Full example follows.

Thanks,

--Steve

IronPython doesn't actually support INotifyPropertyChanged - it only
supports custom type descriptor so that WPF can get at the values
but it doesn't get the change notifications.

You could make an instance of ExpandoObject which does support it:

import clr
clr.AddReference('Microsoft.Scripting.Core')
from Microsoft.Dynamic import ExpandoObject
a = ExpandoObject()
a.name = 'Foo'

Or you could implement INotifiyPropertyChanged on the Person object
and use a property which fires the event changed notification.

My only thought on #2 would be to add another point of indirection.
So rather than updating the global a_person update a_person.real_value
and have that update fire a bunch of changed events.

Hi Dino,

Thanks for your quick answer and for making things clear on INotifyPropertyChanged. 

I'd like to have my own derived classes for this project so I think I'm going to steer clear of ExpandoObject and look into implementing INotifyPropertyChanged.

And I tried out your suggestion for #2, creating a new class:

class Context(object):
    def __init__(self):
        self.person = Person("Alfred")

and then assigning a new Person as the person attribute of the context:

label.DataContext = a_context

def button_click(sender, args):
    a_context.person = Person("Mathilda")

which works (for now) as long as I do the UpdateTarget() and presumably will work as well with implementing INotifyPropertyChanged.

Thanks,

--Steve

Python's __setattr__ hook makes INotifyPropertyChanged easy to implement if
you're willing to pay the performance penalty. Just derive from a class like
this one:

class PropertyChangeNotifier(INotifyPropertyChanged):
    def __init__(self, *trackedNames):
        self._PropertyChanged, self._OnPropertyChanged = pyevent.MakeEvent()
        self._trackedNames = trackedNames
    def add_PropertyChanged(self, handler):
        self._PropertyChanged += handler
    def remove_PropertyChanged(self, handler):

Oops -- I should have pointed out that pyevent.py is in the standard
IronPython distribution; probably in a directory called "samples" or
"tutorial". (Network service in the bus is flaky, so I'm finding it hard to
check.)

Hi Curt,

Thanks, just what I needed and the performance is definitely acceptable if you keep trackedNames to a minimum.

Python's __setattr__ hook makes INotifyPropertyChanged easy to implement if you're willing to pay the performance penalty. Just derive from a class like this one: 

class PropertyChangeNotifier(INotifyPropertyChanged): 
def __init__(self, *trackedNames): 
self._PropertyChanged, self._OnPropertyChanged = pyevent.MakeEvent() 
self._trackedNames = trackedNames 
def add_PropertyChanged(self, handler): 
self._PropertyChanged += handler 
def remove_PropertyChanged(self, handler): 
self._PropertyChanged -= handler 
def __setattr__(self, name, value): 
object.__setattr__(self, name,value) 
if name != "_PropertyChanged" and name != "_OnPropertyChanged": 
if len(self._trackedNames) == 0 or name in self._trackedNames: 
self._OnPropertyChanged(self, PropertyChangedEventArgs(name))

Hi Dino, 

Thanks for your quick answer and for making things clear on INotifyPropertyChanged. 

I'd like to have my own derived classes for this project so I think I'm going to steer clear of ExpandoObject and look into implementing INotifyPropertyChanged. 

And I tried out your suggestion for #2, creating a new class: 

class Context(object): 
def __init__(self): 
self.person = Person("Alfred") 

and then assigning a new Person as the person attribute of the context: 

label.DataContext = a_context 


def button_click(sender, args): 
a_context.person = Person("Mathilda") 

which works (for now) as long as I do the UpdateTarget() and presumably will work as well with implementing INotifyPropertyChanged. 

Thanks, 

--Steve

Subject: Re: [IronPython] DataBinding from IronPython Object to WPF Property 

IronPython doesn't actually support INotifyPropertyChanged - it only 
supports custom type descriptor so that WPF can get at the values 
but it doesn't get the change notifications. 

You could make an instance of ExpandoObject which does support it: 

import clr 
clr.AddReference('Microsoft.Scripting.Core') 
from Microsoft.Dynamic import ExpandoObject 
a = ExpandoObject() 
a.name = 'Foo' 

Or you could implement INotifiyPropertyChanged on the Person object 
and use a property which fires the event changed notification. 

My only thought on #2 would be to add another point of indirection. 
So rather than updating the global a_person update a_person.real_value 
and have that update fire a bunch of changed events.

Subject: [IronPython] -X:EnableProfiler and DLR hosting API
Message-ID: <f9cdf5cb0908060122w51bdf431k604bd11b912f946e@mail.gmail.com>

Thank you for the answer :)
I found this article which tells me that a script can now enable the
profiler from within itself:

http://blogs.msdn.com/curth/archive/2009/04/11/profiler-part-ii-poor-man-s-code-coverage.aspx

<http://blogs.msdn.com/curth/archive/2009/04/11/profiler-part-ii-poor-man-s-code-coverage.aspx>So
I used that method instead, like this:

def begin_profiler():
    import clr
    clr.EnableProfiler(True)
    clr.ClearProfilerData()

def end_profiler():
    ticks_to_ms = 0.00001
    clr.EnableProfiler(False)
    # show top 20 sorted by exclusive time
    for p in itertools.islice(sorted(filter(lambda item: item.Calls != 0,
clr.GetProfilerData(True)), key=lambda item: -item.InclusiveTime), 20):
        print '%s\n%f\t%f\t%d' % (p.Name, p.InclusiveTime * ticks_to_ms,
p.ExclusiveTime * ticks_to_ms, p.Calls)

Seems to work very well :)

I've reproduced this issue. Microsoft.Web.Scripting seems to be doing the right thing ... detecting changes in App_Script and calling runtime.ExecuteFile(path) for the files that changed. However, that's not having any effect. This definitely works stand-alone, so I'll drill into this more. Thanks for the bug report though!

Thanks. The previous release had the correct behavior, so hopefully it isn't hard to do.

Not yet, sorry. I think I can fix that for the next release and make them reload if they've been modified, but I haven't checked if there is a way to do that today. I'll take a look now...

I've noticed that with the latest bits for IronPython for ASP.Net<http://ASP.Net>, files in app_script only seem to be revisited when the app pool is restarted.



For example, if I have a file called hello_world.py in App_Script, and delete that file, the app still executes code in that file as if it were there. If I change a line in the file, that line is not shown as changed until I restart the app pool.



Is this by design, a bug, or something I'm doing wrong?



Thanks,

Adam

All the options should be the same as the command line options.  So they're
documented via ipy.exe /? :)

Are these options for IronPython 2.6 documented anywhere?

Subject: [IronPython] Accessing scope variables
Message-ID: <575551.76177.qm@web34508.mail.mud.yahoo.com>

Hello,

We are hosting IronPython in our Windows forms-based application to allow our customers to write scripts. We allow customers to use our own variables within the script.

public class Variable
{
     string Name;
     int Value;
     ..
}

..
Variable v1 = new Variable("Length", 10);  // Create a variable with Name=Length and Value=10
vars.Add(v1);
Variable v2 = new Variable("Width", 10); 
vars.Add(v1);
vars.Add(v2);


We set custom variables in scriptScope like this.
       
..
            foreach (IVariable aVariable in vars)
            {
                scriptScope.SetVariable(aVariable.Name, aVariable);
            }
..

With this, user can write a function like this

def CalcArea() :
    return Length * Width


In our application, we are dealing with hundreds of variables and functions. As the user deletes or modifies a Variable (here Length and Width), they would like to know where the variables are used. In this example, the variable Length and Width are used in CalcArea function. I can't find a way to identify the list of custom variables used within a function using the API.

Any suggestions? Thanks a lot.

The only way I can think of doing this today would be to use our Parser
And PythonWalker classes to parse the func def and then walk it and look
for NameExpressions.

You'd also need to look for GlobalStatement's, AssignmentStatement,
and AugmentedAssignmentStatement to know if it was a global or not.


OTOH if we fixed this bug (which you can vote on):
http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=15398

you could walk the function objects, get their func_code, and then
look at co_names:

x = 42
def f():
    print x
    y = 42

c = f.func_code
c.co_varnames
('y',)
c.co_names
('x',)

Which looks like it has the global names which would be resolved against
your scope.  I've slowly been fixing more and more of function code but
haven't gotten to this one yet :(

Subject: [IronPython] Reflection.Emit from IronPython: What is the
	equivalent of typeof() in C# ?
Message-ID: <000001ca16d1$2592e400$0f00000a@LITTONDALE>

Hello,

I'm attempting to drive the Reflection.Emit API from IronPython. In C#
typical Reflection.Emit use makes use typeof(...) facility in C#, to enable
the determination of types without needing an instance of that type.

For example, to create an array of .NET CTS Strings in IL from C# one might
do:

generator.Emit(OpCodes.Newarr, typeof(string));

where the second argument to Emit is the element type of the array.

I've tried various alternatives from IronPython, including

generator.Emit(OpCodes.Newarr, System.Type.GetType('System.String'))
generator.Emit(OpCodes.Newarr, str().GetType())
generator.Emit(OpCodes.Newarr, System.String().GetType())
generator.Emit(OpCodes.Newarr, clr.GetClrType(System.String))

however, all of these result in RuntimeType[] rather than String[] in the
generated CIL.

How do I get typeof(System.String) from IronPython?

Hi Michael,

I'm afraid not:

>>> clr.GetClrType('')
TypeError: expected Type, got str

My hopes were momentarily raised when I discovered that your otherwise very
comprehensive book mentions typeof in the index (page 398) - but then I
found that you only use it from C#. 

Cheers,

Rob

You can also just use the type like "System.String" to avoid having to create an instance of the type.

>>> import System
>>> import clr
>>> clr.GetClrType(System.String)
<System.RuntimeType object at 0x000000000000002B [System.String]>

Hi,

When the IronPython parses UTF-8 scripts, it occars every 1024 bytes are broken.
Because UTF-8 charmap has multibyte chars, but parser read only 1024
byte at once.

Mr. Koichi Yamamoto had written a patch for the problem.

I'm glad to commit official repository.

Comments?

(dfugate) OverflowWarning was removed in CPython 2.5.  Removed OverflowWarningException.cs.

Added default constructor for ErrorExpression.  Obviously this type gets generated by many IronPython tests, but code coverage runs weren't picking it up because ErrorExpression methods are either not hit or dead.

Removed IronPython.Runtime.Operations.ScriptScopeOps outright.  The comments indicate this was only needed for Nessie, and Dino thinks removing it will only affect "someScriptScope.__dict__ = 42".

Added sanity test for IronPython.Runtime.Types.SlotFieldAttribute to test_privateBinding.py.  There's no way to indirectly hit this piece of code.

24182 ArgumentNullException raised for functions with many arguments Title is required
                Fix the check to see if we can handle the function

Also fixing 2 import bugs so pygments works out of the box:
                Subclasses of module aren?t handled right ? we go directly to the Scope and fetch the member which avoids calling __getattr__ if it?s defined
                When importing a nested module we don?t pull the resulting module out of sys.modules ? we return whatever we just imported.  But we should check sys.modules so that the module can replace itself before the import is finished and have the replaced version returned.

This has been fixed in 2.6 already but thanks for reporting it.

Unfortunately we don't current accept contributions back to

Hi David,

This still produces RuntimeType[] in the generated CIL :-(

Thanks for trying!

Is this what you're trying to accomplish?

from System.Reflection import *
from System.Reflection.Emit import *
import System
import clr
clr.AddReference('System.Core')

dm = DynamicMethod("test", clr.GetClrType(System.Array[str]), System.Type.EmptyTypes)
ilgen = dm.GetILGenerator()
ilgen.Emit(OpCodes.Ldc_I4_4)
ilgen.Emit(OpCodes.Newarr, str)
ilgen.Emit(OpCodes.Ret)

dlg = dm.CreateDelegate(System.Func[System.Array[str]])
print dlg()

prints:
Array[str]((None, None, None, None))

Here I'm just passing str as the type directly - there's a conversion defined
from PythonType -> System.Type.  But clr.GetClrType(str) and ''.GetType() both
work fine for me (on 2.0.1 and 2.6B2).

That's the same as the fourth example in my original message and doesn't
work. Prompted by your first sentence I've also tried simply,

  generator.Emit(OpCodes.Newarr, System.String)

but I'm still getting RuntimeType[] rather than String[] in the generated
IL.

Thanks,

Rob

Hello,

Here is the solution to my problem, which turns out to be as much a silly
mistake on my part as to how to use the Reflection.Emit API, as it is an
IronPython conundrum.

It turns out the array type for the field, that I was seeing in Reflector
and IL Disassembler was is set by the DefineField call (of course!), rather
than the Emit(Newarr, type) call which simply puts a reference to the new
array on the stack.  The original how-to-do-typeof question still applies,
since this method also takes a type parameter:

Now I've made the change in the right place in my code, I can report that
the following is known to work, a gives a String[] as you would expect in
the generated assembly:

type_builder.DefineField("foo",
System.Type.GetType('System.String').MakeArrayType(1),
FieldAttribute.Private)

For the record, the following expressions supplied by me and others also
work:

str().GetType().MakeArrayType(1)
System.String().GetType().MakeArrayType(1)
clr.GetClrType(System.String).MakeArrayType(1)
clr.GetClrType(type('')).MakeArrayType(1)

Thank you to everybody for your correct answers, now I've figured out how to
use them, and apologies for any confusion I may have caused by prematurely
rejecting your answers before I'd got my act together.  It seems there are
many equivalents of C# typeof in IronPython.

Thanks,

Rob

That's right.
I think Mr. Koichi Yamamoto is yamakox.

I see about fixed in 2.6 already, but it seems that there is no fix
about 2.0.2 ?

I fixed myself to source tree from subversion repository.

Subject: [IronPython] ValueError: cannot assign to value types
Message-ID: <abb783b90908072040k23ec8c75jbc4ddd50ab534aaa@mail.gmail.com>

i'm really stuck trying to change values for an object of type
'Parcel', which comes from the openmetaverse library i'm using. how
this library is implemented i don't have control over, but the given
interface is to make local changes to these Parcel objects, then use
its Update() method to commit the changes. but it seems in IronPython
i can't change these objects.

>>> type(props)
<type 'Parcel'>

>>> props.Name = "Yes"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: cannot assign to value types

after hours of struggling, i found
http://ironpython.codeplex.com/Wiki/View.aspx?title=Value%20Types
which seems to explain why i'm being bit here. bit it also says
"updates are still possible via instance methods on the value type
itself." so isn't "__setattr__" an instance method? seems i'm not able
to use that either:

>>> props.__setattr__("Name", "Yes")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: Attempt to update field 'Name' on value type 'Parcel';
value type fields cannot be directly modified

ok, so what are my options? how do i get around this? i *have* to be
able to update objects of this type somehow.

i can create a new object of that type, but the constructor doesn't
allow me to pre-stock it with values ( since i guess it assumes i'll
be able to change them later), and then of course once it's created i
can't change anything.

__setattr__ it's not a *CLR*-level instance method of the type. IronPython
just makes it look like it is.
One possibility is to simply create an entirely new Parcel from scratch,
assigning values as appropriate. For example, given the following C#
classes:

public struct Point {
    public int x, y;
}
public class Line {
    public Point to, from;
}

You can do this from Python:

F:\tcwb\libs>ipy.exe
IronPython 2.6 Beta 2 (2.6.0.20) on .NET 2.0.50727.4927
Type "help", "copyright", "credits" or "license" for more information.
>>> import clr
>>> clr.AddReference('x')
>>> import Point, Line
>>> l = Line()
>>> l.to.x
0
>>> l.to.x = 1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: cannot assign to value types
>>> l.to = Point(x = 1, y = 2)
>>> l.to.x
1

I am new to IronPython. I am trying to add IronPython scripting  
support to my C# program. I have a number of questions.

Namespaces
----------
Looking at C# examples on WWW, I can see:

using IronPython.Hosting;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;

Where can I get documentation on these namespaces?

Thanks a lot for your reply. I do see DLR description (Microsoft.Scripting
namespace), but I fail to see IronPython.Hosting namespace. Do you know
where can I find the spec on it?

 

Thanks,

Boris

Where can I get documentation on these namespaces?

There probably isn't one. But these are just helpers for functionality
that's in the DLR hosting spec. The source ought to be pretty
self-explanatory.

Message-ID: <6a6c05630908092217y21f63fd2u4811622535f4cf81@mail.gmail.com>

Hi,

I would like to preload an engine instance with references to .NET
namespaces, such that using clr.AddReference in a script is
unnecessary.  To be simple, I've created an engine instance with all
the scope variables that I want, but within a script executed by the
instance, I am finding that clr.AddReference('System') is required to
import System.  Can I handle the adding of the reference in the
construction of the engine instance and if so, how?

Thanks,
Jesse Wiles

You can load assemblies to the runtime via ScriptRuntime.LoadAssembly.

Message-ID: <d5b234f30908100859g48c783b8wffb0e3731ee81@mail.gmail.com>

 I've been unsuccessful at building IronPython 2.6 B2 for a Silverlight 2
environment.  Are there any special requirements other than the Silverlight
2 developer tools for building IPy 2.6 B2 on a vista machine?  I am using
the Silverlight Release build and omitting the SILVERLIGHT_3 flag.
Microsoft.Scripting.Core has numerous System library conflict errors related
to the stubs.cs.  The rest of the errors are related to the inability to
find the IPy libraries in the referenced directory.  Those may clear up if I
can get past the errors related to stubs.cs.

If needed, I can provide specific build error messages...they are
unavailable to me at the moment.

If you see errors in Stubs, then it's definitely not building in
"Silverlight Debug" or "Silverlight Release" configurations. I'll get
the codeplex sources and double check that things are working
properly, but please make sure your building in the Silverlight
configuration.

Sorry for the confusion; the IronPython CODEPLEX sources are NOT
buildable with Silverlight 2; the csproj files contain direct
references to silverlight 3 assemblies. So you need to build with
Silverlight 3 installed. However, if you want to ensure the assemblies
still work on Silverlight 2, you'll have to remove the SILVERLIGHT_3
flag; then you install SL2 and test everything out.

You are NOT required to have the silverlight tools installed to build
the ironpython binaries; just the silverlight 3 runtime.

How come you have a SL2 requirement though? You can't download SL2
from the web anymore, and everyones SL2 installs should be prompting
them to update to SL3. SL3 should be entirely backward comaptible, so
I'd like to know the reason your bound to SL2.

We can port the fix back to 2.0.3 when we do that release.  We're still
not sure when the next 2.0 release will be - it'll probably depend on
the reaction to 2.6 and how quickly people move to that.  I'll add a
comment to the bug.

Sorry to be slow getting back... I'm on vacation.
In attempting to make a test case as you have requested, I suddenly run in
to the following problem:

<console dump>
C:\temp>ipy ipy_bug.py

C:\temp>"c:\program files\Ironpython 2.0.2\ipy.exe" ipy_bug.py
version= adodbapi v2.2.7a1
Executing the command: "select * from Products"
result rowcount shows as= 6. (Note: -1 means "not known")

result data description is:

      ItemNumber      3        4        4   10   255     1

result first ten records are:
(1, 'Widgit', 5.0, Decimal("15.1234"), datetime.datetime(2009, 1, 29, 13, 5,
30)
)
(2, 'Thingamajig, Standard', 505.0, Decimal("0.1000"),
datetime.datetime(2009, 1

(3, 'Left Handed Smoke Shifter', 1.0, Decimal("1000000.0000"),
datetime.datetime

(4, 'Gravel (Bulk)', 100.25, Decimal("32.4567"), datetime.datetime(2009, 1,

(5, 'Tube, Drinking, Plastic, For cold liquids', 500000.0,

(6, 'Annoy-A-Tron', 1.0, Decimal("12.9500"), datetime.datetime(2009, 1, 29,
13,
5, 33))

C:\temp>ipy26 ipy_bug.py

C:\temp>"c:\program files\Ironpython 2.6\ipy.exe" ipy_bug.py
version= adodbapi v2.2.7a1
Traceback (most recent call last):
  File "ipy_bug.py", line 52, in ipy_bug.py
AttributeError: 'module' object has no attribute 'adodbapi'
</console dump>

The offending line is:
adodbapi.adodbapi.defaultIsolationLevel = adodbapi.adXactBrowse

I never have understood why it was necessary to use the
adodbapi.adodbapi.(whatever) construct, but smarter people than me said that
was necessary, and they are correct.  If the redundant-looking entry is not
used, the programs runs without an error message, but does not actually
perform the intended function. If, for example, the line
adodbapi.adodbapi.defaultCursorLocation = adodbapi.adUseClient
is changed to
adodbapi.defaultCursorLocation = adodbapi.adUseClient
then the program will run, but the rowcount will return as -1, rather than
6, because the cursor is not actually changed to a local cursor.

So, to make a long story short: some change in IPy 2.6 has broken a needed
(if ugly looking) feature in adodbapi.
I will file a bug in codeplex as soon as I can isolate a good example.

Sorry to be slow getting back... I'm on vacation.
In attempting to make a test case as you have requested, I suddenly run in to the following problem:

<console dump>
C:\temp>ipy ipy_bug.py

C:\temp>"c:\program files\Ironpython 2.0.2\ipy.exe" ipy_bug.py
version= adodbapi v2.2.7a1
Executing the command: "select * from Products"
result rowcount shows as= 6. (Note: -1 means "not known")

result data description is:

      ItemNumber      3        4        4   10   255     1

result first ten records are:

)
(2, 'Thingamajig, Standard', 505.0, Decimal("0.1000"), datetime.datetime(2009, 1

C:\temp>ipy26 ipy_bug.py

C:\temp>"c:\program files\Ironpython 2.6\ipy.exe" ipy_bug.py
version= adodbapi v2.2.7a1
Traceback (most recent call last):
  File "ipy_bug.py", line 52, in ipy_bug.py
AttributeError: 'module' object has no attribute 'adodbapi'
</console dump>
The offending line is:
adodbapi.adodbapi.defaultIsolationLevel = adodbapi.adXactBrowse

I never have understood why it was necessary to use the adodbapi.adodbapi.(whatever) construct, but smarter people than me said that was necessary, and they are correct.  If the redundant-looking entry is not used, the programs runs without an error message, but does not actually perform the intended function. If, for example, the line
adodbapi.adodbapi.defaultCursorLocation = adodbapi.adUseClient
is changed to
adodbapi.defaultCursorLocation = adodbapi.adUseClient
then the program will run, but the rowcount will return as -1, rather than 6, because the cursor is not actually changed to a local cursor.

So, to make a long story short: some change in IPy 2.6 has broken a needed (if ugly looking) feature in adodbapi.
I will file a bug in codeplex as soon as I can isolate a good example.

Ok, I've finally got SQL server setup in a reasonable state where I can try and repro this.  This is what I'm trying to do.  I have a database called "mydatabase" which contains a table "Table_1" which contains 1 column of type binary(4).  I then attempt to do:

x = rs['Test1']

x.AppendChunk(b)



which fails with:



EnvironmentError: System.Runtime.InteropServices.COMException (0x800A0C93): Operation is not allowed in this context.



This is the same failure I get if I use Shri's proposed work around.  Do you have any idea of what I'm doing wrong or any suggestions on how to tweak this to get the correct simple repro?

Guys:
  Good work on the new release, and the 215 bug fixes. As usual, as soon as the new beta was announced I downloaded and tested it.

Somehow I got the idea that the adodbapi test had been included in the IronPython test suite. Did you only include the tests that already pass?  Issue 18222 is still unfixed -- so adodbapi still fails, and you still cannot pass a read-only buffer as a COM parameter.

I realize that no one has voted up this rather obscure bug. Perhaps if it were titled "fully support DB API 2.0 compliant database access using ADO" it would have gotten more votes. Nevertheless, this issue has been outstanding for 11 months, and is the only remaining failure in adodbapi for versions 2.3 thru 3.1 of python. Please try to get to it before 2.6 final.

Please !!!???

P.S. -- I plan to make a version of adodbapi which uses real ADO.NET<http://ADO.NET>, rather than ADO via COM, but I want the current version to be solid before I start mucking it up.

Subject: [IronPython] FlowDocument XAML syntax highlighting and restructured
	text
Message-ID: <4A80AEB6.2010504@voidspace.org.uk>

Hello all,

Just to let you know I've started a project to generate FlowDocument 
XAML from reStructuredText source. There is also a pygments formatter so 
that source code can be formatted.

The project, rst2xaml is at:

    http://code.google.com/p/rst2xaml/

So far it can cope with rest documents consisting of bold, italics, 
blockquotes and the sourcecode directive!

The pygments formatter looks quite nice though - here is the output 
shown in a FlowDocumentReader:

    http://twitpic.com/dfwu5

The goal is to be able to show highlighted Python examples / tutorials 
alongside an interactive interpreter in the browser with Silverlight / 
Moonlight.

Currently rst2xaml.py itself runs under CPython, but the xaml it 
generates is intended to be used from IronPython with WPF. There is an 
example script, display_xaml.py, that will show generated xaml in a window.

Very cool Michael.

FYI, pygments runs in IronPython except for a but in their _automodule class in pygments/lexers/__init__.py (http://dev.pocoo.org/projects/pygments/browser/pygments/lexers/__init__.py). If you comment out the last 6 lines of lexers/__init__.py, pygments will run under IronPython, but without the lexer module automodule support. That means you have to write

from pygments.lexers.agile import PythonLexer

instead of

from pygments.lexers import PythonLexer

Dino assures me this bug is fixed and will be available in source "soon" - definitely by RC.

I have no clue - any ideas what the issue was there?  We only have 1 bug
that references it and it was fixed a long time ago.

i dunno. i think this behavior needs to be re-thought for Ipy 2.6. i
understand the reasons behind the decision, but the bottom line is
that i'm unable to work with a perfectly valid, legal .NET assembly.
it's one thing to do this as the default behavior, but to not allow
the programmer to override it if that is his choice is not correct in
my opinion.

Just out of curiosity - how would you feel if we enabled the behavior
but issued a warning when it occurred?  In v1.0 when we made this
decision we had no warning support and it could serve as a mitigating
factor in enabling it.  But it could also be too noisy.

It's funny, I just got had to fix a bug in IronPython where they allow
this but it doesn't really work.

Given:

List<SomeValueType> x;
X[0].Bar = 42;

fails to update the list.

OK. Thank you.

The fix is quite important for CJK(Chinese/Japanese/Korean) people.
Because all scripts in UTF-8 are sure fail at parsing.

Yes, many people are looking forward to the release of 2.6,
but it seems that the development gets behind a bit the plan.
I think that the 2.0 will release 1 or 2 times more.

i'd feek ok about any method that at least allowed me to work around
the current situaiton. a warning seems fine to me. even better, an
explicit way for us to enable the behavior without a warning.

If you want an immediate work around I think:

type(props).Name.Info.SetValue(props, value)

might work in 2.6.  You'll need to do "import clr" for "Info" to be available
on the reflected field object.

I actually believe we've been tracking pretty close to the posted plan:

http://ironpython.codeplex.com/Wiki/View.aspx?title=2.6%20Release%20Plan

But that's only indirectly related to 2.0.3 anyway.

If I use the unicodedata module from FePy then it *seems* to work. 
Although I do see a warning that I don't see under CPython:

<string>:1: DeprecationWarning: object.__new__() takes no parameters

Not dug in to see where it comes from.

It's a new warning in 2.6 - it could be that FePy's unicodedata has
something like:

class x(object):
    def __new__(cls, *args):
            return object.__new__(cls, *args)  # shouldn't pass args
    def __init__(self, *args):
            pass

x(42)

Nope, no class definitions - it just uses .NET functionality. It's a 
very short bit of code really - 77 lines of which 30 lines are a 
dictionary defining a category mapping.

Another issue. If you use the programmatic API it blows up with an odd 
error. This is a function that uses a lot of keyword arguments (up to 
seventeen, mainly defaulting to None) and delegates to another function 
that also takes seventeen keyword arguments:

 >>> from docutils.core import publish_string
 >>> publish_string('foo')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Value cannot be null.
Parameter name: method


This works fine with CPython.

There probably isn't one. But these are just helpers for functionality
that's in the DLR hosting spec. The source ought to be pretty
self-explanatory.

No. The setup for the test script fiddles with os.path, but adodbapi itself
makes no changes to sys.modules nor os.path.

Jimmy,

Please see this tweet: http://is.gd/22y9D

I'm running the vmware image of the latest opensuse 11.1 with Mono 2.4.2.3.
The Moonlight/Ipy application I was developing acts like it is loading but
nothing displays.  It works fine using Ipy 2.6 B1 and Moonlight 1.9.5.  The
Clock and Repl python samples (IronRuby 0.9.0 samples) are also broken using
Ipy 2.6 B2 and Moonlight 1.9.6 (the latest).  The background for the clock
displays but not the control.  The Repl simply does not display.
Additionally, tested against the agdlr 0.5.0 samples:
http://twitter.com/railcar88/status/2692911187

My thought is that perhaps building against Silverlight 3 might have broken
compatibility with Moonlight 1.9.6.  It could just as well be something else
on the Mono or Moonlight side too (hopefully not user error :-) ).

I'd like to use the latest of Ipy and the Moonlight Preview of Moonlight 2
to develop against.

Thanks,

Scott

Hi,

Also get Michael's book. The web is pretty lacking in helping you get going,
but the book is invaluable.

Thanks Justin. I have obtained the book yesterday. Indeed, the book is
invaluable. Especially in C# - IronPython integration. I will post a
favorite review on Amazon regarding the book.

 

Here is another question. How do I debug IronPython from C#. 

 

1.      Using Debug flag in options I can put break-points in IronPython
code and single-step  through it. But I cannot view the variables. 

2.      It would be great if somehow I can invoke IronPython shell from a
break-point, so I can interactively examine the code and play with it. Is it
possible?

3.      For some reason Dir() output does not go to Console. Where does it
go?

 

Thanks,

Boris

There probably isn't one. But these are just helpers for functionality
that's in the DLR hosting spec. The source ought to be pretty

In my most recent blogpost about IronRuby and Moonlight (http://blog.jimmy.schementi.com/2009/07/ironruby-at-oscon-2009-mono-moonlight.html) I say this:

Note: the latest Moonlight stable release will not work for IronRuby, you must install the latest Moonlight build from their build bot:http://sublimeintervention.com:8123/GetFile.aspx?id=11487919

There were some bugs in Moonlight that they had to work out to get Ruby working. I believe Python worked as well, but these were "Silverlight Debug" builds from the IronRuby github source (which includes IronPython) without the "SILVERLIGHT_3" flag; you're right that building against SL3 broke the SL2/Moonlight2 compatibility because we now depend on System.Windows.Deployment.ExtensionPart. I think it makes sence to figure out a way to have the same binaries work in Silverlight 3 and Moonlight 2 without rebuilding, so I'll make sure to get that in to IronPython 2.6.

Jimmy,

Please see this tweet: http://is.gd/22y9D

I'm running the vmware image of the latest opensuse 11.1 with Mono 2.4.2.3.  The Moonlight/Ipy application I was developing acts like it is loading but nothing displays.  It works fine using Ipy 2.6 B1 and Moonlight 1.9.5.  The Clock and Repl python samples (IronRuby 0.9.0 samples) are also broken using Ipy 2.6 B2 and Moonlight 1.9.6 (the latest).  The background for the clock displays but not the control.  The Repl simply does not display.  Additionally, tested against the agdlr 0.5.0 samples:
http://twitter.com/railcar88/status/2692911187

My thought is that perhaps building against Silverlight 3 might have broken compatibility with Moonlight 1.9.6.  It could just as well be something else on the Mono or Moonlight side too (hopefully not user error :-) ).

I'd like to use the latest of Ipy and the Moonlight Preview of Moonlight 2 to develop against.

Thanks,

Scott

Sorry for the confusion; the IronPython CODEPLEX sources are NOT
buildable with Silverlight 2; the csproj files contain direct
references to silverlight 3 assemblies. So you need to build with
Silverlight 3 installed. However, if you want to ensure the assemblies
still work on Silverlight 2, you'll have to remove the SILVERLIGHT_3
flag; then you install SL2 and test everything out.

You are NOT required to have the silverlight tools installed to build
the ironpython binaries; just the silverlight 3 runtime.

How come you have a SL2 requirement though? You can't download SL2
from the web anymore, and everyones SL2 installs should be prompting
them to update to SL3. SL3 should be entirely backward comaptible, so
I'd like to know the reason your bound to SL2.

I looked at this closer looking at all combinations of __new__/__init__
being defined and calling the super class w/ and w/o arguments.  Our
behavior on warnings seems to be correct - we're a little less strict
on when we report errors though which I'll fix.

Did you get no warnings from CPython 2.6?  The one other difference
I've noticed is that CPython seems to only warn once - even when I
replace all of the functions in warnings to get past it's report-once
caching - where we warn multiple times.  I'm inclined to not replicate
the behavior that specifically right now.

try:
    import warnings
except ImportError:
    import _warnings as warnings

def warn_explicit(*args):
    print 'my warn', args
    import sys
    x = sys._getframe(0)
    while x:
        print x.f_code
        x = x.f_back

warnings.warn_explicit = warn_explicit
warnings.warn = warn_explicit
warnings._show_warning = warn_explicit
warnings.showwarning = warn_explicit
import _warnings
_warnings.warn_explicit = warn_explicit
_warnings.warn = warn_explicit
_warnings._show_warning = warn_explicit
_warnings.showwarning = warn_explicit

print 'I warn:'
class x(object):
    def __init__(self, *args):
        object.__init__(self, *args)
    def __new__(cls, *args):
        return object.__new__(cls, *args)

x(42)


print 'I warn once in cpy:'
for i in xrange(2):
    class x(object):
        def __init__(self, *args):
            object.__init__(self, *args)
        def __new__(cls, *args):
            return object.__new__(cls, *args)

    x(42)

Sorry to be slow getting back... I'm on vacation.
In attempting to make a test case as you have requested, I suddenly run in to the following problem:

<console dump>
C:\temp>ipy ipy_bug.py

C:\temp>"c:\program files\Ironpython 2.0.2\ipy.exe" ipy_bug.py

Traceback (most recent call last):
  File "ipy_bug.py", line 52, in ipy_bug.py
AttributeError: 'module' object has no attribute 'adodbapi'
</console dump>

The offending line is:
adodbapi.adodbapi.defaultIsolationLevel = adodbapi.adXactBrowse

I never have understood why it was necessary to use the adodbapi.adodbapi.(whatever) construct, but smarter people than me said that was necessary, and they are correct.  If the redundant-looking entry is not used, the programs runs without an error message, but does not actually perform the intended function. If, for example, the line
adodbapi.adodbapi.defaultCursorLocation = adodbapi.adUseClient
is changed to
adodbapi.defaultCursorLocation = adodbapi.adUseClient
then the program will run, but the rowcount will return as -1, rather than 6, because the cursor is not actually changed to a local cursor.

So, to make a long story short: some change in IPy 2.6 has broken a needed (if ugly looking) feature in adodbapi.
I will file a bug in codeplex as soon as I can isolate a good example.

Guys:
  Good work on the new release, and the 215 bug fixes. As usual, as soon as the new beta was announced I downloaded and tested it.

Somehow I got the idea that the adodbapi test had been included in the IronPython test suite. Did you only include the tests that already pass?  Issue 18222 is still unfixed -- so adodbapi still fails, and you still cannot pass a read-only buffer as a COM parameter.

I realize that no one has voted up this rather obscure bug. Perhaps if it were titled "fully support DB API 2.0 compliant database access using ADO" it would have gotten more votes. Nevertheless, this issue has been outstanding for 11 months, and is the only remaining failure in adodbapi for versions 2.3 thru 3.1 of python. Please try to get to it before 2.6 final.

Please !!!???

P.S. -- I plan to make a version of adodbapi which uses real ADO.NET<http://ADO.NET>, rather than ADO via COM, but I want the current version to be solid before I start mucking it up.

Awesome, thanks!  I've found and I believe I have a fix for the import issue - it was a regression from fixing

Ok, I've finally got SQL server setup in a reasonable state where I can try and repro this.  This is what I'm trying to do.  I have a database called "mydatabase" which contains a table "Table_1" which contains 1 column of type binary(4).  I then attempt to do:



import System

conn = System.Activator.CreateInstance(System.Type.GetTypeFromProgID("ADODB.Connection"))

connstr = "driver={SQL Server};Server=localhost;Database=mydatabase;Initial Catalog=mydatabase;Trusted_Connection=True;"

conn.ConnectionString = connstr

rs = System.Activator.CreateInstance(System.Type.GetTypeFromProgID("ADODB.RecordSet"))

rs.Open("Table_2", conn, 1, 2, 2)  # source, active connection, cursor type (adOpenKeyset), lock type (adLockPessimistic), CommmandType (adCmdTable)

rs.AddNew()

b = System.Array[System.Byte]((2,3,4,5))

x = rs['Test1']

x.AppendChunk(b)



which fails with:



EnvironmentError: System.Runtime.InteropServices.COMException (0x800A0C93): Operation is not allowed in this context.



This is the same failure I get if I use Shri's proposed work around.  Do you have any idea of what I'm doing wrong or any suggestions on how to tweak this to get the correct simple repro?

Guys:
  Good work on the new release, and the 215 bug fixes. As usual, as soon as the new beta was announced I downloaded and tested it.

Somehow I got the idea that the adodbapi test had been included in the IronPython test suite. Did you only include the tests that already pass?  Issue 18222 is still unfixed -- so adodbapi still fails, and you still cannot pass a read-only buffer as a COM parameter.

I realize that no one has voted up this rather obscure bug. Perhaps if it were titled "fully support DB API 2.0 compliant database access using ADO" it would have gotten more votes. Nevertheless, this issue has been outstanding for 11 months, and is the only remaining failure in adodbapi for versions 2.3 thru 3.1 of python. Please try to get to it before 2.6 final.

Please !!!???

Vernon Cole

P.S. -- I plan to make a version of adodbapi which uses real ADO.NET<http://ADO.NET>, rather than ADO via COM, but I want the current version to be solid before I start mucking it up.

I definitely get a warning with IronPython 2.6 and *no* warning with 
Python 2.6.

I tried digging a bit further in, but it's late and I'm hampered by the 
programmatic API not working with 2.6B2.

The functions with 17 arguments that don't work... This is how you call 
docutils programatically. I can trigger the bug with the rst2html.py 
scripts but to dig into what is calling it I really want to call the 
APIs directly.

Ahh, yes, an easy work around would be to pass one of the args w/ defaults
as a keyword argument w/ it's default value.

Jimmy,

That's great news that IPy 2.6 will be compatible with Moonlight 2 and
Silverlight 3!

The Moonlight build bot link is broken.  My search for an alternative link
is coming up short.

Thanks,

In my most recent blogpost about IronRuby and Moonlight (
http://blog.jimmy.schementi.com/2009/07/ironruby-at-oscon-2009-mono-moonlight.html)
I say this:

Note: the latest Moonlight stable release will not work for IronRuby, you
must install the latest Moonlight build from their build bot:
http://sublimeintervention.com:8123/GetFile.aspx?id=11487919

There were some bugs in Moonlight that they had to work out to get Ruby
working. I believe Python worked as well, but these were "Silverlight Debug"
builds from the IronRuby github source (which includes IronPython) without
the "SILVERLIGHT_3" flag; you're right that building against SL3 broke the
SL2/Moonlight2 compatibility because we now depend on
System.Windows.Deployment.ExtensionPart. I think it makes sence to figure
out a way to have the same binaries work in Silverlight 3 and Moonlight 2
without rebuilding, so I'll make sure to get that in to IronPython 2.6.

Hi,
I'm developing an application for MacOsX build with python and cocoa.  
Now I want to convert my project to a Windows .Net project.
But I have this problem: in one of my classes i use pysqlite module.
How i can use this module on IronPython?
Thanks

Marco

Right now you can't use it because the pysqlite/sqlite3 module involves C
code, and last I checked it does not work with ironclad. You could look into
System.Data.SQLite from http://sqlite.phxsoftware.com/, but it won't be a
drop-in replacement for your current sqlite code.

maybe some rewrapping of this is possible ?

fepy has one!
This is compatible with db-api 2.0 :)
This uses System.Data.SQLite.dll

If you just want the database modules without all of FePy, you can get
them from http://bitbucket.org/jdhardy/adonet-dbapi/ (click on "Get
Source"). It's the same code in a smaller package.

That's highly experimental and currently 3-5x slower than SQLite. Really 
not ready to use yet (and still not compatible with pysqlite anyway).

Hi All, 

 

I'm a newbie in IronPython. I've got an interest to learn and work in IronPython.

 

Can anyone suggest me about the scope in IronPython and developing career in it?

 

I'm a software engineer and have 3 years of professional experience in .NET. So how would it be for me to put my shoes in IronPython?

 

Thanks

Pratik.

Subject: [IronPython] rst2xaml progress
Message-ID: <4A834C6A.3070403@voidspace.org.uk>

Hello all,

Just to let you know about the progress of my rst2xaml project:

    http://code.google.com/p/rst2xaml/

It now supports the following docutils markup features:

    * title and headings
    * paragraphs
    * bold
    * italics
    * superscript
    * literal blocks
    * inline literals
    * line blocks
    * bullet lists
    * enumerated lists
    * the pygments code-block directive

Almost enough to be useful. :-)

I've attached a screenshot of a simple rest document rendered to xaml 
and displayed with WPF.

Unfortunately the subset of text formatting supported by Silverlight is 
frankly pathetic, so it means lots more hoops to jump through. The 
pygments xaml formatter already works, and can output xaml that can be 
used in a Silverlight / Moonlight TextBlock. For the other docutils 
features I will have to be a bit more imaginative and stack separately 
formatted TextBlocks inside other components, which is a bit more tricky...

All the best,

Michael

i'm still getting used to the tracebacks that IPy / .NET produces. I'm
used to CPython always telling me which line of code to look for the
problem at. Is there a way to find where in my .py program the source
of this problem lies? It looks like gobbledegook to me:

It looks like this code is hosted somewhere.  So who is catching the
exception in this case?  If it's you then you can do:

pythonEngine.GetService<ExceptionOperations>().FormatException(exception);

to get a standard Python version of the stack trace.

W/o doing that the .NET stack trace is basically useless.  Sometimes code
is interpreted which gives you no info and even when it's compiled
it's usually as DynamicMethod's which don't have debugging info associated
with them.  If you enable debug mode though (-X:Debug from the command line
or setting DebugMode on a ScriptRuntimeSetup) then you'll at least get some
.py file line numbers in all the noise.  But there's also lots of other
frames which show up from the DLR and IronPython infrastructure which
makes it confusing.

If the code isn't hosted and you're getting this exception from pure
Python code then it'd be a bug.  One thing to watch out for is if you've
done from System import * then "except Exception, e:" will give you
the .NET exception object.

But when I add a DataRow with this code:

mydatar = DataRow()

Any ideas?

This class has no public constructors - you aren't intended to construct

See the documentation for details:

http://msdn.microsoft.com/en-us/library/system.data.datarow.aspx

Subject: [IronPython] IronPython 2.6 RC1 must fix bugs
Message-ID: <1A472770E042064698CB5ADC83A12ACD0380BA27@TK5EX14MBXC116.redmond.corp.microsoft.com>

As we're winding down towards RC1 and I wanted to do one last check to see if there's a must-fix bug that we've somehow missed.  Based upon our own triage, the number of votes, etc... it's entirely possible that we've de-prioritized an important bug that might enable a new scenario, make an existing scenario work better or easier, or just generally make IronPython more enjoyable for your day to day use.

So please let us know if you have a bug that you think we should go back and take a second look at fixing now rather than later.  Thanks!

Subject: [IronPython] Using IronPython as an assembly in dotNET
Message-ID: <4A844A12.5020408@duber.cz>

Hi there everyone,

I have a problem I can't seem to figure out.

I want to use IronPython as an assembly via dotNET, I managed to load it 
as an assembly and access various constructors, classes etc...

However, I have a problem with executing Python code from the host 
application. I'm using 3ds Max to load up the assembly via dotNET. The 
code looks like this:

Assembly = dotNetClass "System.Reflection.Assembly" -- loading the 
assembly class
Assembly.LoadFrom "C:\IronPython-2.0.1\IronPython.dll" -- loading IronPython

ironPythonHosting = dotNetClass "IronPython.Hosting.Python" -- loading 
the hosting class
pythonEngine = ironPythonHosting.CreateEngine() -- creating an engine

Now, when I execute:

pythonEngine.ExecuteFile("C:\\tst.py")

it runs smoothly and executes the tst.py and whatever Python code that's 
inside.

Now, I want to execute the code directly, not via a saved file. I tried 
this:

pythonEngine.Execute("print 'TEST'")

but it throws me an error:

-- Error occurred in anonymous codeblock; filename: ; position: 344
-- Runtime error: dotNet runtime exception: Late bound operations cannot 
be performed on types or methods for which ContainsGenericParameters is 
true.

Also, if I execute the Python code inside a file, is there a way to get 
the result/feedback from the code back to the host application? Via 
dotNET or IronPython? Or anyhow? So that I can write more complex tools 
that'd communicate with Pyhon code from within 3ds Max.

Thanks a lot in advance, cheers,

- Lukas Dubeda

What language are you doing this from?

ScriptEngine.Execute has an overload which is generic and an overload
which is not generic.  The generic version will get the result and
convert it to the provided generic type.  It looks like for some reason
you end up trying to call the generic version here.  Does the language
have support for generics?  If so you could do:

engine.Execute<object>(...) (C# syntax)

which would be the same as the non-generic version.

For communication I'd suggest injecting a class into the ScriptScope
You execute the code in.  Then the Python code can call back on it or
subscribe to events on it.

Hey, thanks Dino,

some interesting points. However, I'm not a programmer, I'm more of a 
"scripter" so all I'm familiar with is Python and MAXScript (native 3ds 
Max scripting language).

I have no idea how to access the generic/non-generic engine, further 
more, I have no idea what the difference is.

As for scope, I can do that, the problem is, I have no idea how exactly 
to do that. Is there a documentation on this subject somewhere?

Thanks a lot for the tips, I appretiate it.

- Lukas

There's documentation on the hosting APIs over here:

http://dlr.codeplex.com/Wiki/View.aspx?title=Docs%20and%20specs

But basically you want to do:

scope = engine.CreateScope()
scope.SetVariable("my_object_model", new MyObjectModel())
engine.Execute("print my_object_model.SomeCall()", scope)

As a workaround for Execute you can call ExecuteAndWrap which
doesn't have a generic overload.  You'll just need to call
.Unwrap() on the resulting value to get the real object back.

A quick search seems to indicate that MaxScript 9 doesn't
support generics.  I have no clue what the latest version is
though so I'm not sure how relevant that was (it was from 2006).

Thanks again,

I'll dig into the documentation and see if I can come up with a solution.

As for "generics", since I have no idea what these are and I know 
MAXScript quite well, I assume they really don't exist in this language.

MXS is a very simple, focused, language that only works within 3ds Max. 
It wasn't intented for such broad use as Python for example.

Cheers,

- Lukas

Python isn't that hard to learn, at least not the basics.  The
tutorial on the python.org website is a good place to start.  The
IronPython downloads are free.  It's reall a matter of installing the
interpreter and starting to test things.

I you're a dot Net developer, you can prototype things more quickly
and easily and interactively with IronPython.  Most of the common dot
Net libraries work with the IronPython implementation.

Now, for your real question - jobs/career.  I surf the job boards
pretty frequently just to see what's going on and how people are using
Python.  I've seen at least one job posted a number of months back in
New York City in the financial sector.  It referred to a third party
app with a Python API.  I assumed (perhaps falsely) that the app was
the Resolver spreadsheet, because the company that makes it does
target the stock market sector.  I believe you can still download the
base Resolver product for free for non-commercial use (basically to
learn it).

The short on learning IronPython or IronRuby or any other dynamic
language is that you're really learning the language, not just the dot
Net implementation of it.  IronPython gets more and more consistent
with the main Python implementation (CPython) with each release.  Even
now, Python programmers are still hard to come by.  My one boss
referred to them as being "so darn hard to find."  So, IronPython or
jython or PyPy or just plain Python - it's not a bad skill to have.

My two cents.  Hope this helps.

Carl T.

Jobs in Python are growing steadily. IronPython is also growing in 
adoption, especially in companies that were already using a mix of C# 
and Python - IronPython is an obvious fit. Despite this I've not seen 
many jobs specifically asking for IronPython developers. My guess is 
that they know that developers with *either* Python experience or .NET 
experience will find IronPython easy.

All the best,

Michael Foord

I am developing a C# app and considering to embed IronPython scripting.
Using TaskManager, I have noticed that 

- the minimal C# ConsoleApp that includes DLR and IronPython is 8.7MB in RAM
- while the minimal C# ConsoleApp that does not include DLR and IronPython
is only 1.5MB in RAM	

Unfortunately extra 7MB in RAM is too much to justify scripting. Is there
any idea what this 7MB is used for? And more importantly, does anyone know
how to reduce the RAM size?

Thanks!

Subject: [IronPython] InvokeMember with three or more parameters.
Message-ID: <4A891277.4060007@gmail.com>

Hello.

I have Python code:

class Broker ( object ) :

     def validation( self, info, provider_manager ):
         pass

     def check( self, payment, payment_manager, provider_manager ):
         pass

and try to call methods by this c# code:

operations = scriptEngine.CreateOperations();
var scriptSource = 
scriptEngine.CreateScriptSourceFromString(script,SourceCodeKind.Statements);
scriptCode = scriptSource.Compile();
scriptCode.Execute();
scriptScope = scriptCode.DefaultScope;
broker = scriptEngine.Execute(string.Format("{0}()","Broker"),scriptScope);

bool validationResult = operations.InvokeMember(broker, "validation", 
paymentInfo, providerManager);

operations.InvokeMember(broker, "check", payment, paymentManager, 
providerManager);


Invoke validation method is success, but invoke check method throws 
NotImplementedException with stack trace:

System.NotImplementedException: Method or operation not implemented.
    ? Microsoft.Scripting.Runtime.DynamicOperations.InvokeMember(Object 
obj, String memberName, Boolean ignoreCase, Object[] parameters)
    ? Microsoft.Scripting.Hosting.ObjectOperations.InvokeMember(Object 
obj, String memberName, Object[] parameters)

Looks like 2 paramters called correct, but more than 2 throws exception 
in all cases.

Why it happens?

(dfugate) Complete revamp of the IronPython debugging test plan which is now entirely in pydoc format.  This will be used as a model for all future IronPython test plans on major features.  Not very pretty to look at, but I will be investigating the use of Sphinx (http://sphinx.pocoo.org) in the near future.

(dinov) 18222 ADO parameter method .AppendChunk will not accept a python buffer 
                Add IComConvertible interface.  Whenever IronPython calls into the COM binder we attempt to apply our own COM conversions.  PythonBuffer is the only supported COM conversion currently and it converts to a byte array.

14022 Floating point values incorrect on German Windows XP 
We are incorrectly using ?en-US? in the string formatter because it usually formats the same as Python does.  But a user can modify the en-US locale and change the formatting which breaks IronPython?s formatting.  So instead we should use the invariant culture.

15398 Most co_* attributes raise NotImplementedError 
                Implements co_names, co_nlocals, and co_cellvars.  Makes co_code return an empty string.  Fixes co_varnames so it includes arguments & local variables.  Adds a lot of doc comments to code objects.  
                There?s some plumbing in ClassDefinition/FunctionDefinition/ScopeStatement so that we track the extra info and pass it to the creation of FunctionCode objects.
                
6277 Implement re.purge() 
                Add a limited cache on RE_Pattern objects and implement re.purge which flushes the cache

21979 marshal.dumps works on subtypes of tuple, list, dict, set, frozenset 
                Moving to an exact type test, and enabling the CPython test

20162 Error message misreports required number of args
                This is currently passing as expected, adding a test

Fixes a regression caused by 20174.  When importing from a package we still need to publish the child module into the parent package.

Also tightens up the errors reporting when calling object.__new__/__init__.  We were more lex than CPython before.

We haven't implemented support for more than 3 parameters :)

In 2.6 I just fixed > 3 params for the Invoke case (not InvokeMember)
and I can fix > 3 for InvokeMember/CreateInstance as well before
2.6 ships.

The preferred way to do this though is to do a GetMember<T> where
T is a delegate type with > 3 paraemters.  Then you can just invoke
the delegate.

What version of IronPython are you using?  Have you ngen'd the binaries?
Ngen will significantly reduce the amount of private working set IronPython
uses.

I assume you don't have a "site.py" or the standard library present or I
think it'd probably be more.

On my machine (some post-RC1 Windows 7 build) I see:
        C# Hello World: 1.5MB Private working set
        "ipy.exe -S" (IronPython 2.6B2, ngen'd binaries): 4.7MB private working set

Giving us about 3.2MB to start up IronPython including its REPL.

2.6 certainly is better from a working set perspective than 2.0 is but the
gains there are mainly for large applications.

2.6 should also see better WS on non-Vista platforms.  This is because
we've fixed the base addresses up to make sure that ngen'd binaries don't
require being re-based when they get loaded.

We haven't really focused on memory usage of hello world at all.  But we'd
welcome a bug on CodePlex to draw our attention to the problem.

Subject: [IronPython] IronPython DLLs distributing
Message-ID: <38ef96bd0908171205r6670a337la26f5a9ba1559544@mail.gmail.com>

Hello everyone. What is the best way to distribute IronPython applications?
I've seen that all the IronPython .dll files need to be in the same folder
as the application .exe and the application .dll in order to run. Is it
possible to install the IronPython .dll files in one common location for all
applications to use? Or do they need to be distributed with every IronPython
application? That would seem to be inefficient, especially since the .dlls
increase the total size of the application.

Thanks.

This is only the same problem as any .NET application distributing DLLs 
it depends on. The 'standard' solution is to install assemblies into the 
GAC. You could do this in your installer.

Guys:
  Good work on the new release, and the 215 bug fixes. As usual, as soon as the new beta was announced I downloaded and tested it.

Somehow I got the idea that the adodbapi test had been included in the IronPython test suite. Did you only include the tests that already pass?  Issue 18222 is still unfixed -- so adodbapi still fails, and you still cannot pass a read-only buffer as a COM parameter.

I realize that no one has voted up this rather obscure bug. Perhaps if it were titled "fully support DB API 2.0 compliant database access using ADO" it would have gotten more votes. Nevertheless, this issue has been outstanding for 11 months, and is the only remaining failure in adodbapi for versions 2.3 thru 3.1 of python. Please try to get to it before 2.6 final.

Please !!!???

Vernon Cole

P.S. -- I plan to make a version of adodbapi which uses real ADO.NET<http://ADO.NET>, rather than ADO via COM, but I want the current version to be solid before I start mucking it up.

How do you run compiled scripts(dll) by C# host?

Hitherto, I run IronPython scripts by my C# host with the following.
- Microsoft.Scripting.Hosting.ScriptEngine
- Microsoft.Scripting.Hosting.ScriptScope

I think we can use the implementation
IronPython.Runtime.Operations.PythonOps.InitializeModule() .
The code doesn't use Microsoft.Scripting.Hosting.[ScriptScope] but
Microsoft.Scripting.Runtime.[Scope] .
We can make instances of [Scope], but we cannot make ones of
[ScopeScope] directly.
Because both ScriptScope.ScriptScope() and ScriptScope.Scope are
defined 'internal'.

Comments?

You can convert between Scope and ScriptScope by using
Microsoft.Scripting.Hosting.Providers.HostingHelpers.

What Curt says is true but I would suggest doing scriptRuntime.LoadAssembly instead.

Once you do that you can do engine.ImportModule (an extension method defined in the Python class) do get a ScriptSource for any of your compiled modules.  InitializeModule may change from major version to major version of IronPython - but engine.ImportModule is a fixed public API.

OK. but after imported not set data to the scope or the scriptscope.

Thanks!
I made it the following.

| public static void InitializeModule(string ModulePath, string/*!*/ main)
| {
|     var pythonEngine = Python.CreateEngine();
|     var path = Path.GetFullPath(ModulePath);
|     var precompiled = Assembly.LoadFile(path);
|
|     pythonEngine.Runtime.LoadAssembly(typeof(string).Assembly);
|     pythonEngine.Runtime.LoadAssembly(typeof(System.Diagnostics.Debug).Assembly);
|     pythonEngine.Runtime.LoadAssembly(precompiled);
|
|     var pythonContext =
HostingHelpers.GetLanguageContext(pythonEngine) as PythonContext;
|
|     try
|     {
|         scriptScope = pythonEngine.ImportModule(main);
|     }
|     catch (SystemExitException ex)
|     {
|         Console.WriteLine(ex.ToString());
|     }
| }

But the problem dated ahead about UTF-8 parsing again :(
To be fixed myself...

Dear All,

 

what about coexistent IronPython and IronRuby in the same application (not
passing objects between IronPython to IronRuby and viceversa)?

In detail, I'd like to script my application with either IronPython or
IronRuby: the DLR is here for this!

Where I store locally my scripts (an Xml file) I can save the type of
script, so I can decide on a script base the language.

But with all subsequent releases of IPY and IRB, have always different
Microsoft.Scripting dlls: at the moment, IPY 2.6beta2 has 2.6.907.0, while
IRB has 1.0.

If I statically link Microsoft Scripting dll is a problem: the only solution
I have is to bring IPY and IRB dlls in different folders and dynamically
load the assemblies.

How can be solved this?

 

Thanks in advance.

Hello Dino,

Sorry - I lost the original email so am sending a fresh one. :-)

You asked what bugs in particular we would like to see fixed in 2.6 
final. I am *very* keen to see pdb work with IronPython 2.6, and in 
particular set_trace and post_mortem which don't work in Beta 2. There 
is an open codeplex issue for this somewhere...

His issue (as I understand it) is not having a common build of 
IronPython and IronRuby that use the same version of the DLR.

Ivan and Michael,

 

sorry if I have written bad. I try to rewrite.

Microsoft.Scripting is statically referenced by IPY and IRB. Each IPY and
PRB distribution come with his own Microsoft.Scripting: at the moment, IPY
2.6beta2 has 2.6.907.0, while IRB has 1.0.

Now, I need to host DLR, not specific DLR language, in my application: I?d
like allow my script choosing which language to use for scripting (the
script is contained in an XML file the has an attribute for language
selection).

So I?d like to reference in my application the Microsoft .Scripting
assembly, configure app.config with all DLR languages available (not only
IPY and IRB), and implement logic that calls the hosting api selecting the
language.

The question is: which Microsoft.Scripting assembly I have to reference? How
about IPY and IRB updates?

 

I use this mail to congratulate with you for your books!

Dear All,

 

what about coexistent IronPython and IronRuby in the same application (not
passing objects between IronPython to IronRuby and viceversa)?

In detail, I?d like to script my application with either IronPython or
IronRuby: the DLR is here for this!

Where I store locally my scripts (an Xml file) I can save the type of
script, so I can decide on a script base the language.

But with all subsequent releases of IPY and IRB, have always different
Microsoft.Scripting dlls: at the moment, IPY 2.6beta2 has 2.6.907.0, while
IRB has 1.0.

If I statically link Microsoft Scripting dll is a problem: the only solution
I have is to bring IPY and IRB dlls in different folders and dynamically
load the assemblies.

How can be solved this?

 

Thanks in advance.

That's convenient because I've been working on fixing that one along
w/ another related bug for getting PyDev debugging to work.

This one will require that you provide a -X:Tracing command line flag
so that we always have the tracing code gen.  But it works on my machine
as of a couple of days ago (there's just other things which are still
failing).

So expect this to be in 2.6RC1.

Please note that IronPython sources found on IronRuby's GIT repository are NOT actually an exact match or completely compatible with IronPython sources on CodePlex.  You see for IronPython we transform some uses of the "System" C# namespaces into "Microsoft".  IronRuby doesn't do this last time I checked.  E.g., compare what's in http://github.com/ironruby/ironruby/blob/adb33b18780e5f2a7e050fd38ebc58750ec1cf5b/ndp/fx/src/Core/Microsoft/Scripting/Compiler/BoundConstants.cs  to http://ironpython.codeplex.com/sourcecontrol/changeset/view/57668?projectName=IronPython#760473.

The best way in my opinion to get compatible versions of IronPython+IronRuby is to use the DLR CodePlex site - http://dlr.codeplex.com/SourceControl/ListDownloadableCommits.aspx#DownloadLatest.  Cross-language interop between Iron* languages was one of the primary motivations for creating the DLR site:)

Compile on 64-bit?  :)

I have a guess of what the problem is here but I haven't run a test to
Confirm.  I recently ran into a similar issue when I increased the
number of constants we were generating - except for I was just trying
to pre-compile a single file.

If you want to build from source you can modify ToDiskRewriter.cs to add a
new member variable:

private Dictionary<ConstantExpression, Expression> _constantCache;

And then in VisitConstant replace:
                    Expression serialized = exprSerializable.CreateExpression();
                _constants.Add(serialized);

                return AstUtils.Convert(
                    Expression.ArrayAccess(_constantPool, AstUtils.Constant(_constants.Count - 1)),
                    serialized.Type
                );
With:


                Expression res;

                if (!_constantCache.TryGetValue(node, out res)) {
                    Expression serialized = exprSerializable.CreateExpression();
                    _constants.Add(serialized);

                    _constantCache[node] = res = AstUtils.Convert(
                        Expression.ArrayAccess(_constantPool, AstUtils.Constant(_constants.Count - 1)),
                        serialized.Type
                    );
                }

                return res;

and then add:

_constantCache = new Dictionary<ConstantExpression, Expression>();

To EnsureConstantPool()

If that doesn't work, or you don't want to build from source, I'll attempt to repro it and see what's going on.

Subject: [IronPython] sys.argv empty  in compiled scripts
Message-ID: <E3E4C7D6B896A043805949D136C327F404FB473C@SYDEXCVS0.aar.com.au>

Hi all,
 
I just
http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=24373
<http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=24373>  to
report this but I would appreciate a work-around if anyone has one.  The
text of the issue is below.
 
Thanks for any help!
 
Regards,
Kyle
 
Description 

This is like
http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=12283 but
seems to refer to a different exe.

I downloaded the pyc in the samples today this problem is still an issue
- or is an issue again.

In this case sys.argv is empty in compiled scripts. See below for an
example.

bash-3.2$ ipy
IronPython 2.0 (2.0.0.0) on .NET 2.0.50727.3053
Type "help", "copyright", "credits" or "license" for more information.
>>> ^Z
bash-3.2$ cat broken.py
import sys
print str(sys.argv)
bash-3.2$ ipy broken.py foo bar
['broken.py', 'foo', 'bar']
bash-3.2$ ipy.exe pyc.py /main:broken.py
Input Files:
Output:
broken
Target:
ConsoleApplication
Platform:

Machine:

Compiling...
Saved to broken
bash-3.2$ ./broken.exe foo bar
['']
bash-3.2$

Hello.

Thank you for answer.

How can I create script object without code generation same like:

scriptEngine.Execute(string.Format("{0}()","Broker"),scriptScope);

?

This should do it:

scriptScope.GetVariable<Func<object>>("Broker")();

Subject: [IronPython] FolderBrowserDialog does not show folders
Message-ID: <38ef96bd0908191102x97f4f48h356463d8402c90cf@mail.gmail.com>

I've noticed an issue with the FolderBrowserDialog window from IronPython.
When I display it with the ShowDialog method in a compiled script (through
pyc.py), it does not show the TreeView of folders. It will display the
Description title and the buttons, however. If I run the script straight
through the interpreter, it will display the folders just fine. For
reference, I also tried the OpenFileDialog and SaveFileDialog, and those
show up correctly in both methods. Is this a bug, or am I doing something
wrong?

Sample code below:

*import clr
clr.AddReference("System.Windows.Forms")
from System import *
from System.Windows.Forms import *

dlg = FolderBrowserDialog( )
dlg.Description = "Testing..."
dlg.ShowDialog( )
*

Are you compiling w/ the "/target:winexe" option?  You'll need to provide that for doing WinForms development.

Yes, I am. The full command line I'm using is:
*"C:\Program Files\IronPython 2.0.2\ipy.exe" pyc.py
/out:FolderBrowserDialogTest /main:FolderBrowserDialogTest.py /target:winexe
FolderBrowserDialogTest.py*.

The dialog window does come up with every control except the tree view of
folders.

It is fixed in 2.6.  I don't see another bug on this anywhere else
so the new bug will be good to keep around for 2.0.3.

It's a COM issue. The emitted Main needs to be tagged with the [STAThread]
attribute.

...which has been fixed for IronPython 2.6. You might be able to use the 2.6
pyc.py script against 2.0.

Hello,

This is a known bug - and if it isn't fixed in 2.6 it really needs to 
be. :-)

You can access the command line arguments through System.Environment.

from System import Environment
args = Environment.GetCommandLineArgs()

How would I tag Main with the [STAThread] attribute in IronPython? I thought
IP didn't yet have the ability to use attributes...

Unfortunately that is something that needs to be done in the Pyc 
compiler. Did you try Curt's suggestion of using the 2.6 Pyc.py?

If 2.6 doesn't work unmodified there's also adding the 2 needed lines
to 2.0's pyc:

     mainMethod = tb.DefineMethod('Main', MethodAttributes.Public | MethodAttributes.Static, int, ())
+    if targetKind == System.Reflection.Emit.PEFileKinds.WindowApplication:
+        mainMethod.SetCustomAttribute(clr.GetClrType(System.STAThreadAttribute).GetConstructor(()), System.Array[System.Byte](()))
     gen = mainMethod.GetILGenerator()

Yes, I did. The 2.6 pyc.py did not work when run against 2.0.2, but I
downloaded IP 2.6 Beta 2 and now the FolderBrowserDialog comes up correctly.
So I guess I'll just use 2.6 from now on. Thanks!

From marco.parenzan at libero.it  Thu Aug 20 09:56:37 2009
From: marco.parenzan at libero.it (Marco Parenzan)
Date: Thu, 20 Aug 2009 09:56:37 +0200
Subject: [IronPython] IronPython and ReportLab
Message-ID: <007301ca216b$be7bc480$3b734d80$@parenzan@libero.it>

Dear All,

 

I'm trying to use IronPython 2.0.2 with ReportLab PDF. I have downloaded it
(version 2.3) with FePy for unicodedata.py.

I used this code for testing (from Magnus Lie Hetland "Beginning Python"):

 

from reportlab.graphics.shapes import Drawing, String

from reportlab.graphics import renderPDF

 

d = Drawing(100, 100)

s = String(50, 50, "Hello World", textAlign='middle')

 

d.add(s)

 

renderPDF.drawToFile(d, "HelloWorld.pdf", "HW")

 

The execution fails:

 

Traceback (most recent call last):

  File "renderPDF01.py", line 9, in renderPDF01.py

  File "C:\marco.parenzan\Python\reportlab\graphics\renderPDF.py", line 268,
in drawToFile

  File "C:\marco.parenzan\Python\reportlab\pdfgen\canvas.py", line 947, in
save

  File "C:\marco.parenzan\Python\reportlab\pdfbase\pdfdoc.py", line 223, in
SaveToFile

  File "C:\marco.parenzan\Python\reportlab\pdfbase\pdfdoc.py", line 245, in
GetPDFData

  File "C:\marco.parenzan\Python\reportlab\pdfbase\pdfdoc.py", line 422, in
format

  File "C:\marco.parenzan\Python\reportlab\pdfbase\pdfdoc.py", line 883, in
format

  File "mscorlib", line unknown, in GetString

  File "mscorlib", line unknown, in GetChars

  File "mscorlib", line unknown, in Fallback

  File "mscorlib", line unknown, in Throw

UnicodeDecodeError: ('unknown', u'\x93', 11, 12, '')

 

The failed row shows:

 

882:    def format(self, document):

883:        strings = map(str, self.strings) # final conversion, in case of
lazy objects

884:        return string.join(strings, "")

 

I have discovered that the problem is in this string, that is the header for
the PDF file:

 

# Following Ken Lunde's advice and the PDF spec, this includes

# some high-order bytes.  I chose the characters for Tokyo

# in Shift-JIS encoding, as these cannot be mistaken for

# any other encoding, and we'll be able to tell if something

# has run our PDF files through a dodgy Unicode conversion.

PDFHeader = (

"%PDF-1.3"+LINEEND+

"%\223\214\213\236 ReportLab Generated PDF document http://www.reportlab.com
<http://www.reportlab.com%22+LINEEND> "+LINEEND)

 

Which is appended at the beginning of str variable. The problem is in the
four characters: \223\214\213\236, which are badly converted into Unicode.
Accordingly to the comment (and to PDF documentation) the four bytes are not
fixed, but can be any number, better if >128 because of automatic detection

Do you know why?

 

Uuhh, reportLab is very long to execute (Vista32, CoreDuo 2.5GHz,
4GbRAM):about 20 seconds.

Dear All,

 

I downloaded IPY2.6beta2 to test this script:

 

from reportlab.graphics.shapes import Drawing, String

from reportlab.graphics import renderPDF

 

d = Drawing(100, 100)

s = String(50, 50, "Hello World", textAlign='middle')

 

d.add(s)

 

renderPDF.drawToFile(d, "HelloWorld.pdf", "HW")

 

IPY 2.0.2 takes 20 seconds; IPY 2.6beta2 about 8! But it takes
long....CPython takes less that a second.

Marco,

 

in CPython reportlab we expect all strings to be either bytes in utf8
encoding 

or unicode. I suspect that the default string encoding in ironpython is 

something other than that so a lot of reportlab string handling may be
broken.

 

Does ironpython support unicode directly ie u'Hello World'?

 

I would not expect reportlab to work out of the box with ironpython. PDF
doesn't 

use unicode (normally) and most of the output is in Adobe specific
encodings.

 

I don't think the real problem lies in our use of strange bytes (although
that 

may not help). If the string in question is the special sequence we use at
the 

beginning of the document then the issue is deeper since that string doesn't


normally require any special manipulation (ie we expect it to appear
literally 

in the output as a sequence of bytes). If we are unable to write bytes
directly 

to a file then many other problems will also need to be found and fixed.

 

This problem also arises in Python 3.x so may eventually be solved for you.

 

As to why reportlab takes so long to execute I cannot say.

(For context, I've only ever used ReportLab with CPython.  I do use

IronPython for other things, though).

 

> Does ironpython support unicode directly ie u'Hello World'?

 

Yes.  IronPython is like Python 3.x in that there are only unicode

strings (`str is unicode` evaluates to True).

 

> As to why reportlab takes so long to execute I cannot say.

 

IronPython is faster than CPython with some things, but CPython is

much, much faster at starting up than IronPython.  I suspect that

Marco is just seeing the regular slow startup of IronPython.

 

Cheers,

Tony

I use generators in IronPython.
if a exception occars in the one, I cannot get correct stack traces.
How to get the trace?

The following, my codes.

	}
	catch (Exception ex)
	{
		string type = ex.GetType().ToString();

Boys I have a news.

 

Executing code interactive, I have an important result:

-          Launching IPY: 3seconds

-          from reportlab.graphics.shapes import Drawing, String: ? seconds

-          renderPDF.drawToFile(d,
"C:\users\marco.parenzan\desktop\uuu.pdf", "HellO"): 1 second!!!!!!!!!!!

(all timings are my counting in my mind!)

 

I have not taken in count this! Sorry, but these are my first seriour
experiments with IPY.

So I can:

-          preload IPY engine (not a bad idea)

-          preload reportlab (also not bad). I can execute statement from
engine(?from reportlab.graphics.shapes import Drawing, String?), but, is
there an API that allow making this via hosting (scriptscope.import?)?

Where can I read about long startup time?

What about import? Why long time? Which are the differences with CPython?

 

Thanks in advance

Other results.

 

I have hosted IPY in a test C# application in which I separate ScriptScope
creation from execution: specifically, I create scope one time, import
modules, and then execute, 100 times.

Timings are ok:

 

Python Startup Elapsed time: 10595

Execution 0 Elapsed time: 1454ms

Execution 1 Elapsed time: 55ms

Execution 2 Elapsed time: 38ms

Execution 3 Elapsed time: 32ms

Execution 4 Elapsed time: 32ms

Execution 5 Elapsed time: 35ms

Execution 6 Elapsed time: 27ms

Execution 7 Elapsed time: 27ms

Execution 8 Elapsed time: 27ms

Execution 9 Elapsed time: 25ms

Execution 10 Elapsed time: 39ms




Execution 99 Elapsed time: 22ms

 

At the moment for me is ok (waiting for a solutions, or, at least, to
understand the 10 seconds!).

 

Another question:. This is the code I use to create the scope:

 

    __pyEngine = Python.CreateEngine();

    __pyEngine.SetSearchPaths(__pySearchPaths);

 

    __pyScope = __pyEngine.CreateScope();

    __pyEngine.Execute("from reportlab.graphics.shapes import Drawing,
String", __pyScope);

    __pyEngine.Execute("from reportlab.graphics import renderPDF",
__pyScope);

 

 


and I use the scope to execute the subsequent code

 

d = Drawing(100, 100)

s = String(50, 50, "Hello World", textAlign='middle')

 

d.add(s)

 

renderPDF.drawToFile(d, "HelloWorld.pdf", "HW")

 

The thing I dislike is sharing the single scope among the multiple execution
of scripts during process life: I?d like to recreate scope every time, but
at the moment I have the discussed module load cost. Is there any way to
load the module at engine level (a sort of global) that all scopes can view,
without importing every time?

 

Thanks in advance

standard Python behavior applies -- if "foo" is already in sys.modules, it
won't be imported again. Instead, the name will just be added to the current
scope.

When you say "startup time" in this context -- that includes the time it
takes to import the modules?

Curt,

thanks for tip: it's ok. That's the code:

            __pySearchPaths = new
List<string>(Properties.Settings.Default.PySearchPaths.Split(';'));
            __pyEngine = Python.CreateEngine();
            __pyEngine.SetSearchPaths(__pySearchPaths);
            __pyEngine.ImportModule("reportlab.graphics");
            __pyEngine.ImportModule("reportlab.graphics.shapes");

            ScriptScope scope = __pyEngine.CreateScope();

            ScriptWriter writer = new ScriptWriter();
            // an helper class I use to write python code in C# code 
            writer.Clear();
            writer.Write("from reportlab.graphics.shapes import Drawing,
String");
            writer.Write("from reportlab.graphics import renderPDF");
            writer.Write("d = Drawing(100, 100)");
            writer.Write("s = String(50, 50, 'Hello world',
textAlign='middle')");
            writer.Write("d.add(s)");
            writer.Write(@"renderPDF.drawToFile(d, 'HW.pdf', 'Hello World
{0}')");
            __pyEngine.Execute(writer.Script(false), scope);

About startup time: yes, the first five lines takes 10/11 seconds!
With your tip I have solved my problem, but I don't understand the
difference between IPY and CPython (1 seconds from start to end).

	Marco

Is there a reason you can't just call FormatException for both cases?  Depending on how the exception is propagated there may be more data in the exception Data property which we need to pick out and format to accurately display it.

I use generators in IronPython.
if a exception occars in the one, I cannot get correct stack traces.
How to get the trace?

The following, my codes.

/// <summary>

IronPython import time remains much slower than CPython.  I think you've seen from the differences between 2.0 and 2.6 that we've already made significant progress in improving this - and we certainly plan to continue pushing on it with each release.

One way to improve startup time today is to use the pyc tool (in Tools\Scripts in the IronPython install) to pre-compile your .py files.

(dfugate) - test_gc.py:  314470 was closed as Won't Fix ages ago, but the test cases were never updated.  Modified them to reflect that this is considered an incompatibility, not a bug
- test_descr.py:  314130

- test_scope.py: 149066 is fixed
- iptest.assert_util: improved stderr_trapper and stdout_trapper.  Propagated these changes down to test_syntax and _warnings_test.py
- test_builtinfunc.py: CP24249 not really fixed
- test_file.py:  extended a regression on file's 'buffering' param
- test_nt.py:  added a regression for CP1217.  Fixed
- test_re.py:  added a regression for re.search(..., buffer(...))
- test_thread.py:  CP22746 is fixed
- excel.py: 372472 might be fixed.  CP18614 is fixed

(dinov) A few changes to improve perf of some of the shootout tests:
	Generators ? ensure CheckSetActive() can be inlined
	Lists slice assign ? if we are assigning from an immutable/non-list RHS then lock the LHS and only once rather than on each assignment
	Conversion to bool call sites ? a common pattern is checking for None & a single type (List, tuple, str, int, etc?).  Update the pre-generated sites to include checks for null which return the appropriate value.  This prevents us from bouncing around updating call sites and switch back and forth between the (type) & None sites.
	Sequence unpacking ? if we have a tuple just return it?s data array instead of copying it in the slowest possible way.

OK. I rewrote to the following:

| catch(Exception ex)
| {
|     var pythonContext =
HostingHelpers.GetLanguageContext(pythonEngine) as PythonContext;
|     Igs.Trace.Error(pythonContext.FormatException(ex));
| }

But I havn't get stack traces upper the generator yet :(

(dinov) Fixes for two tracing related bugs:

24313    The frame received from sys.settrace is not the actual frame
                This is the bulk of the change.  This includes:
                                We no longer create fake FunctionCode objects when building up traceback frames.  Instead our code gen, stack trace updates, and PythonDynamicStackFrame objects have been updated to have the FunctionCode object for the actual function.  For modules this means we need to flow the function code object into the generated module function.  We also get a new DelayedFunctionCode expression which allows us to create the function code object after the code generation for module/class/function definitions is complete.  This lets us create the function code which can hold onto the generated lambda and the generated lambda can refere back to the function code object.

                It also has a cleanup to function code to remove support for ScriptCode?s over there.  This ends a circular dependency between our code objects and ScriptCode objects.

                Our trace back listener is updated to only use 1 thread static for storing all frames.  Previously we had a stack of traceback listeners (which still needs to exist) and inside each traceback listener we had our own list of frames.  This unifies all lists of frames.  Because of this there?s some additional coordination needed when a traceback function throws an exception.

                But when the user calls sys._getframe now we can go and look at this unified static list of traceback frames and pull the frame object from there.  And now all the frames have consistent identities.

23650 Pdb set_trace and post_mortem
                Adding a new ?X:Tracing option which enables these to work.  The problem here is that tracing needs to be enabled all the time, not just when sys.settrace() has been called.  This option makes that possible.

Also fixing a bug reported by Mike Stall that del frame.f_trace doesn?t work.

Can you include the generator code?  If I do:

using System;
using Microsoft.Scripting.Hosting;
using IronPython.Hosting;

public class Test {
    public static void Main(string[] args) {
        var engine = Python.CreateEngine();

        try {
            engine.Execute(@"
def f():
    raise Exception('hello generator')
    yield 42

def g():
    f().next()

g()
");
        } catch(Exception e) {
            Console.WriteLine(engine.GetService<ExceptionOperations>().FormatException(e));
        }
    }
}

Then this outputs:

Traceback (most recent call last):
  File "<string>", line 7, in g
  File "<string>", line 3, in f
Exception: hello generator

I did use the preferred way to format the exception but they should be equivalent.

runpy is setting __package__ to an empty string.  Looks like CPython doesn't
warn when the string is empty because if I do:

import runpy
x = runpy.run_module('foo', run_name = '__main__', alter_sys=True)

CPython doesn't warn. So the fix is easy enough.

But it's interesting CPython no longer calls runpy.run_module anymore. I
guess it's calling runpy._run_module_as_main as there's a big comment saying
should we make this public.

You need to override and call the base __new__ instead of __init__.  .NET has a simpler construction model than Python does and __new__ is what best corresponds to .NET constructors.

class Derived(Test.Base):
    def __new__(cls, i):
        return Test.Base.__new__(cls, i)

d = Derived()

When you inherit from a .NET type and wish to provide an alternate 
constructor you need to override __new__ instead of or as well as __init__.

*class **Derived*(Test.Base):

       def __new__(cls):
          return Test.Base.__new__(cls, 2)


    *def **__init__*(self):

        pass

Won't that still blow up? What will .NET use for i in the constructor if 
you don't provide an argument?

Yes, you're right, too much copying and pasting :)

Subject: [IronPython] IronPython and IronRuby interop with IronRuby 0.9
Message-ID: <4A900EBD.7050408@voidspace.org.uk>

Hello all,

I've played a little bit with IronPython and IronRuby interop with the 
IronRuby 0.9 binaries.

A very basic example works as expected:

IronPython 2.6 Beta 2 (2.6.0.20) on .NET 2.0.50727.4927
Type "help", "copyright", "credits" or "license" for more information.
 >>> import clr
 >>> clr.AddReference('IronRuby')
 >>> from IronRuby import Ruby
 >>>
 >>> engine = Ruby.CreateEngine()
 >>> source = engine.CreateScriptSourceFromString("puts 'Hello from Ruby'")
 >>> scope = engine.CreateScope()
 >>>
 >>> source.Execute(scope)
Hello from Ruby
 >>>


However my attempts to use a Ruby library fails. The same code works 
when executed from ir.exe:

 >>> import clr
 >>> clr.AddReference('IronRuby')
 >>> clr.AddReference('Microsoft.Scripting')
 >>>
 >>> from Microsoft.Scripting import SourceCodeKind
 >>> from IronRuby import Ruby
 >>> engine = Ruby.CreateEngine()
 >>> source = engine.CreateScriptSourceFromString("require 'date'", 
SourceCodeKin
d.Statements)
 >>> scope = engine.CreateScope()
 >>> source.Execute(scope)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
Exception: no such file to load -- date
 >>>

I tried adding a reference to IronRuby.Libraries to the runtime 
associated with the Ruby engine (using runtime.LoadAssembly) but this 
didn't help.

Requiring Ruby modules I've written myself doesn't blow-up but doesn't 
populate the scriptscope they are executed in with anything. Likewise 
calling engine.ExecuteFile('foo.rb') returns an empty ScriptScope.

Any ideas?

All the best,

Michael Foord

Ok, so setting the engine search paths solves the failure to find the
library, but the ScriptScope is still coming back empty. In the example
below I would have expected to see 'd' in the ScriptScope.

c:\Binaries\IronRuby\bin>ipy.exe interop.py
[]

>From this code:

import clr
clr.AddReference('IronRuby')
clr.AddReference('Microsoft.Scripting')

from System import Array

paths = [r'C:\Binaries\IronRuby\lib\IronRuby',
r'C:\Binaries\IronRuby\lib\ruby\1.8']
array = Array[str](paths)

source_code = "require 'date'\nd = Date::civil(2003, 4, 8)\n"

from Microsoft.Scripting import SourceCodeKind
from IronRuby import Ruby
engine = Ruby.CreateEngine()
engine.SetSearchPaths(array)
source = engine.CreateScriptSourceFromString(source_code,
SourceCodeKind.Statements)
scope = engine.CreateScope()
source.Execute(scope)

print dir(scope)

Hehe - well I can fish the contents of the library I required from 
engine.Runtime.Globals, which seems right as I'm requiring it in the 
global namespace. I'm still surprised the ScriptScope is empty.

clr.AddReference('IronRuby')

from IronRuby import Ruby
from System import Array

paths = [r'C:\Binaries\IronRuby\lib\IronRuby', r'C:\Binaries\IronRuby\lib\ruby\1.8']
array = Array[str](paths)

engine = Ruby.CreateEngine()
engine.SetSearchPaths(array)

scope = engine.CreateScope()
source = engine.Execute('''
require 'date'

def d
  Date::civil(2003, 4, 8)
end
''', scope)

print scope.d()
print engine.Runtime.Globals.Date

---

Top-level methods, not local variables, are published in the scope.
Classes and modules are published in Runtime.Globals scope.

And this works too (the value of the last expression is returned):
print engine.Execute('''
require 'date'
Date::civil(2003, 4, 8)
''')

Hehe - well I can fish the contents of the library I required from engine.Runtime.Globals, which seems right as I'm requiring it in the global namespace. I'm still surprised the ScriptScope is empty.

I am hosting IronPython in my application and have python scripts calling some of my C# functions. I was wondering if there was a way to figure out which line of the script I am at from inside my C# function.

Thanks,

(ddicato) Changes the allocation scheme of global variables, cached constants, and CallSites for increased 

access speed and throughput, most notably in function calls. Increased performance comes at the 

price of ~100ms startup time, which we consider to be an acceptable tradeoff.

(dfugate) Trying to fix another spurious failure in test_superconsole.py.  This time around the COM member completion test case seems to randomly take longer than 10 seconds to execute on some of our SNAP machines.  I've modified the test to capture all of stdout, emit more meaningful output when it fails, and reorganized the calls to time.sleep (we need to sleep before taking over stdout/stderr again).

Message-ID: <14B852A5C6341946B80C2B53B8BF51151DF058BBB4@NLCLUEXM11.connect1.local>

Hi,

I have implemented some piece of code that should execute a python-script. In this script I want to call a c#-function.
First, I Generate a module (context to work in):

 _scriptRuntime.Start(true);
 _scriptRuntime.ScriptScope.SetVariable("class", this); ('this' is CClassName')

Then I get the class:

PythonType pType = _scriptRuntime.ScriptScope.GetVariable("CClassName") as PythonType;

Create an instance of the object

_Class = _scriptRuntime.ScriptScope.Engine.Operations.CreateInstance(pType, new object[] { });

[...] (do some other tings)

>From the python script, I want to call the function:

return class.doSomething(parameter)

The code throws an exception:

'CClassName' object has no attribute 'doSomething'.

What am I making wrong? CClassName has a public method doSomething()

Thanks for U're help.

Greetings

Is CClassName a public type?  It'll need to both have public members and also be public its self.

If that's not the problem I'm having trouble understanding exactly what's going on.  Is "return class.doSomething(parameter)" supposedly Python code?  Or are you doing this from C#?  "class" is a keyword in Python so I don't see how it's Python code.

How much python will you let your users execute?
Are they just typing in formulas or are they accessing data structure?

The Python Tutorial http://docs.python.org/tutorial/index.html   or
http://www.diveintopython.org might be a good place to start, but if they
will not be allowed to forms loops, etc both might be too much.  Can you
post an example if what someone would be entering with your program?

Hi Bruce,

thanks for your answer.

> How much python will you let your users execute?

Potentially everything that can be put into

ScriptEngine.CreateScriptSourceFromString(
      Expression, _SourceCodeKind.Expression_).Execute(ScriptScope)

> Are they just typing in formulas or are they accessing data structure?

Normally they type in simple formulas. But they are also allowed to type 
in formulas that access functions, properties of classes/objects/data 
structures and generators.

> The Python Tutorial http://docs.python.org/tutorial/index.html   or 
> http://www.diveintopython.org might be a good place to start, but if

These are all nicely written introductions to python "programming". But 
that's too much: As Expression one can only enter "one-liners" - no 
structured programs, no function or class definitions, no control flow, 
no import statements ... simply no statements at all.

> Can you post an example if what someone would be entering with your program?

"Distance * AvgSpeed"

"Distance**0.9 if Distance > 0 else 5"

"sum([pos.time for pos in positions where pos.type = 7])"

"complicated_function1(a,b) + complicated_function2({ param1: c, param2: 
42 })"

where Distance, AvgSpeed, positions, a, b, c, ... are variables from the 
ScriptScope.

Unfortunately I don't think such a documentation exists (not that I'm 
aware of but the internets is a big place). I wish it did - and if you 
write one then please make it public.

The Python grammar is a good place to get the definitive syntax allowed 
in expressions, at least if you can read BNF.

So you are looking for something more along the lines of this

https://developer.mozilla.org/en/Core_JavaScript_1.5_Guide/Expressions
or this
https://www.cs.drexel.edu/~rweaver/COURSES/ISTC-2/TOPICS/expr.html

But for python.

This http://www.greenteapress.com/thinkpython/html/book003.html  comes
close, but again it is too programming oriented.

I'll keep an eye out, but If you need something right away I'd modify the
Javascript Pages.  The info is available under a Creative Commons License,
and it would not take too much time to make it 'pythonic'.  I think the
problem you are going to find is most python intro information is geared
towards learning via the interactive interpreter (out of your scope) or too
technical like the BNF grammer from the language reference.

Hi,

I found my problem - thanks for the help Dino. CClassName was not public. Now it works fine.

Greetings,
Georg

Is CClassName a public type?  It'll need to both have public members and also be public its self.

If that's not the problem I'm having trouble understanding exactly what's going on.  Is "return class.doSomething(parameter)" supposedly Python code?  Or are you doing this from C#?  "class" is a keyword in Python so I don't see how it's Python code.

Subject: [IronPython] Call methods from Python-Script

Hi,

I have implemented some piece of code that should execute a python-script. In this script I want to call a c#-function.
First, I Generate a module (context to work in):

 _scriptRuntime.Start(true);
 _scriptRuntime.ScriptScope.SetVariable("class", this); ('this' is CClassName')

Then I get the class:

PythonType pType = _scriptRuntime.ScriptScope.GetVariable("CClassName") as PythonType;

Create an instance of the object

_Class = _scriptRuntime.ScriptScope.Engine.Operations.CreateInstance(pType, new object[] { });

[...] (do some other tings)

>From the python script, I want to call the function:

return class.doSomething(parameter)

The code throws an exception:

'CClassName' object has no attribute 'doSomething'.

What am I making wrong? CClassName has a public method doSomething()

Thanks for U're help.

Greetings

Message-ID: <eff3b3530908270621m5a8ad75bvaa49aabb0598233f@mail.gmail.com>

Hi there,

After many hours running different experiments, I still can't find a
way to embed IronPython 2.x in a ASP.NET 3.5 web site.

I have read this:
http://ironpython-urls.blogspot.com/2008/10/ironpython-2-and-fifth-assembly.html

and this:
http://devhawk.net/2008/10/21/The+Fifth+Assembly.aspx

and tried the solution on this CodePlex workitem:
http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=19126

... but nothing works.

If I use the "shipped" Microsoft.Scripting.ExtensionAttribute.dll, I
get the "ambiguous..." compilation error that originated the workitem
19126

If I use the "modified" Microsoft.Scripting.ExtensionAttribute.dll
attached to the workitem, it refuses to be loaded. When I try to
instantiate the engine, I get an error telling me that the
Microsoft.Scripting.ExtensionAtribute cannot be loaded. It seems that
IronPython 2.0.2 expects versions 0.9.0.0, and the patched DLL is
1.0.0.0

I tried to solve the last issue using a "dependentAssembly" node in
the web.config, like this:
      <dependentAssembly>
        <assemblyIdentity
name="Miscrosoft.Scripting.ExtensionAttribute"
publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.9.0.0" newVersion="1.0.0.0"/>
      </dependentAssembly>

... but it doesn't work either. The DLL cannot be loaded.

I tried to compile my own Microsoft.Scripting.ExtensionAttribute.dll
using the "type forwarding" trick mentioned in Michaeld's post, but
then I run into signing issues, and my DLL can't be loaded.

I even tried a suggestion discused here some time ago, about
recompiling IronPython taking away the
Microsoft.Scripting.ExtensionAttribute project, and using 3.5 as a
target (adding references to System.Core), but it seems it is not as
simple as that: As soon as I start changing targets, I start getting
more and more "collitions" with System.Core and IronPython's own
implementations.

So, in a nuthshell, I downgraded to IPy 1.1 (and I *hate* having to do
that!), which is old, but works like a charm.

But I *really, really* would like to find a proper solution to this,
or at least a workarround that... *works*, without having to mess
around with IronPython's source code.

I'm very sad because this problem is also reproducible with the last
beta of IPy 2.6, so it seems we're going to get another major release
that cannot play well with ASP.NET 3.

Is there anything I can do yo embed IronPython 2 in a ASP.NET 3.5 application?

Thank you very much,

To get around the signing issues you can run "sn -Vr Microsoft.Scripting.ExtensionAttribute.dll" on
your built version if you build it w/ our public key.  The public key is in our source distributions
as "MSSharedLibKey.snk".

I had intended for 2.6 to be lined up w/ the previously shipped extension DLL but it looks like
it's not.  We should also put out an updated DLL for 2.0.3 - I'll look into doing that.

Success!

I can confirm that the generated 0.9.0.0 version works perfect with
IPy 2.0.2 final release.
Once again, thank you very much for your quick response!

Message-ID: <76b190ae0908280639k718ef575o6766cbc0d42ecfb8@mail.gmail.com>

Hi,

I have been using IronPython 2.0.2 to develop a Microsoft SharePoint
application. I use IronPython studio (Integrated with Visual Studio 2008).
When I build the project, I get an executable along with IronPython.dll and
IronMath.dll which I need to redistribute with the executable. But when I
try to create an executable using PYC I get an executable along with a dll
(say Main.dll with Main.exe). In this case, I need to redistribute Main.dll,
IronPython.dll, IronMath.dll, IronPython.Modules.dll,
Microsoft.Scripting.Core.dll, Microsoft.Scripting.dll etc., So I need to
know if it is possible to get the same way as IronPython studio provides
without using the studio (using command line or any other tool)

You might be able to use al.exe to link them together - but otherwise no.  Is the problem having both Main.dll + Main.exe (which we could presumably fix)?  Or is it just the large number of assemblies overall?

I used to think that would be great back when I used py2exe, but once I
built a script to build an MSI, the need went away.  For me having real
install/uninstall, shortcut and registry setting capabilities trumps a
single exe file.

Hi,

I have been using IronPython 2.0.2 to develop a Microsoft SharePoint
application. I use IronPython studio (Integrated with Visual Studio 2008).
When I build the project, I get an executable along with IronPython.dll and
IronMath.dll which I need to redistribute with the executable. But when I
try to create an executable using PYC I get an executable along with a dll
(say Main.dll with Main.exe). In this case, I need to redistribute Main.dll,
IronPython.dll, IronMath.dll, IronPython.Modules.dll,
Microsoft.Scripting.Core.dll, Microsoft.Scripting.dll etc., So I need to
know if it is possible to get the same way as IronPython studio provides
without using the studio (using command line or any other tool)

You might be able to use al.exe to link them together - but otherwise no.  Is the problem having both Main.dll + Main.exe (which we could presumably fix)?  Or is it just the large number of assemblies overall?

Subject: [IronPython] IronPython Tools and IDEs
Message-ID: <4A9C3FD5.4010501@voidspace.org.uk>

Hello all,

I've written a roundup of the IronPython support in several of the major
IDEs (Visual Studio, SharpDevelop, Wing, Eclipse with PyDev), plus a
bunch of other 'standard' IronPython and Python development tools:

    - Other Editors
    - Windbg SOS
    - Code Quality Checkers
    - Debugging and the Python Pdb Module
    - Code Coverage and Profiling
    - Refactoring and Complexity

All the best,

Michael Foord
