Under Mono, it's emitting a character on each key-down/key-up event, and

Disclaimer: I'm fairly new to C# and .NET in general.

Using IronPython 0.9.2. on .NET 2.0.50.215.44 w/ SharpDevelop 2.0.0 build
408

I've been trying to use a modified version of the supplied Embed4.cs example
to run from within AutoCAD (just to see if I can get it to work). It
compiles fine but when I load and run it I get the exception listed below. I
tried "caspol -m -af c:\path\to\IronPython.dll" but it errors out saying
IronPython.dll is not strong named. Do I need to recompile IronPython.dll or
am I heading in the wrong direction all together? Any help/tips would be
greatly appreciated.

I ran into the same problem using our product (LabVIEW) but the fix is
fairly simple - go into AssemblyGen.cs of the IronPython assembly and delete
the last parameter (domain.Evidence) of the two DefineDynamicAssembly()
methods.

The problem comes up when you try to host the IronPython engine inside any
AppDomain other than the DefaultDomain (as I assume you are doing in
AutoCAD, we are doing in LabVIEW and as you would find if you tried
ASP.NET<http://ASP.NET>).
The most common way to create a new AppDomain is with null evidence, because
you typically rely on the assembly evidence to handle CAS (as you were
trying to do with caspol). Even if you do domain.Evidence when creating your
own AppDomain, you still get null - there is something about the
DefaultDomain that we are not inheriting.

If you read the docs on DefineDynamicAssembly(), you'll see that only fully
trusted callers can supply evidence - and somehow we are not...I'm still
trying to figure out what's the special invocation to make it work with the
evidence, but so far I've only found one way - create your own evidence when
creating your AppDomain and add MyComputer as the Zone. I'm not about to
ship that code as it seems to break just about every part of CAS, but it is
a clue...

Hi Folks,

Apologies if this is a FAQ but I couldn't find anything in the archives.

I am writing a GUI Designer in IronPython.
 print Form.Text
 <property# Text on Form>

I am probably missing something simple but how do I get the actual
text/value of the property.

I suspect that the "Form" you are referencing is the
System.Windows.Forms.Form class.
Once you have instance, it should just work:

f = Form()
f.Text = "Hi"
print f.Text

I hope this helps

Message-ID: <4342D756.2090801@softwaremind.pl>

Hi,

Few days ago I wrote about a problem with Options.FastEval. I noticed 
today that accidentally it was posted as replay to some other topic and 
I'm not sure that anyone has seen it. So here it is again:

---

Last time I wrote here I was concerned with memory consumption and 
performance of embedding IronPython. I decided then to use the FastEval 
option.

I think I found some error in this mode. In code below the last line 
would throw "Key not found in dictionary." exception caused by the 
"None" term. When you don't use the FastEval the code runs properly.

       static void Main(string[] args)
       {
           IronPython.AST.Options.FastEval = true;
           IronPython.AST.Options.DoNotSaveBinaries = true;

           PythonEngine engine = new PythonEngine();

           engine.SetVariable("item", null);
           object value = engine.Evaluate("item == None");
       }

Also, could you please explain what exactly are the differences between 
the two modes.

PS: Just found that it also doesn't work for the "str" builtin function 
but didn't have time to try others.

Hi  Szymon,

Sorry for delayed response.

The exact difference between the two modes is that FastEval does not
generate IL to be executed. Instead, it walks the abstract syntax tree
and evaluates the expressions directly.

The reason you are seeing the error is that the name resolution for the
expression evaluator doesn't consider built-in names (str, int, None,
...). There may be bugs beyond this simple one, but after getting the
name resolution to consider built-in names, referencing "str", "None"
and the like does work.

I am going to include the fix in the 0.9.3 release.

Martin

Thanks for this most-needed project.

Is there a Visual Studio plug-in for IP for colorizing, debugging,
completion, etc? (Or hooks into other IDEs?)
(I saw the message on launching the CLR debugger - but one-stop shopping is
nice.)

Are most current uses of IP: (a) stand-alone, (b) inside-out (IP as "main"
and controller for existing non-IP objects), or (c) outside-in (C# main
embedding IP as scripting language)? (Of course, your view of "in" and "out"
may vary depending on perspective.)

Thanks,
m

I don't think there is any VS plug-in for IronPython for syntax
coloring, debugging support, intellisense etc. However I know of few
people using xemacs with the extension "python-mode.el". I think it does
support syntax coloring but I am not sure whether it goes beyond that.

 

As for the uses of IronPython, it is used in all of the ways you list.
If there is a pre-dominant one or not, I am not certain. Few months ago
the focus was on the b) - using IronPython to communicate with .Net
objects. Many people also embedded IronPython and used it as a scripting
engine for their applications. As for the standalone use, my feeling is
that to fully enable the scenario, we need to run many more standard
Python modules. We are getting there though

 

I hope this helps.

Martin

Thanks for this most-needed project...

Is there a Visual Studio plug-in for IP for colorizing, debugging,
completion, etc? (Or hooks into other IDEs?)

(I saw the message on launching the CLR debugger - but one-stop shopping
is nice...)

Are most current uses of IP: (a) stand-alone, (b) inside-out (IP as
"main" and controller for existing non-IP objects), or (c) outside-in
(C# main embedding IP as scripting language)AN>? (Of course, your view
of "in" and "out" may vary depending on perspective...)

Thanks,

m

If you have more than one version of .Net installed, it could be that the "wrong" version has been started.  This article discusses getting that same error code:

http://weblogs.asp.net/cschittko/archive/2005/04/05.aspx

and points to this MSDN article that shows how you could use an application configuration file (for your VB6 app, presumably) to require the .Net version used by IronPython:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpcontargetingnetframeworkversion.asp

Good luck...

This same program in interpreted C# or Java (as opposed to JITed) runs
about the same speed as CPython (~110ms on my machine).  IronPython
takes almost 3 seconds in the inner loops.  Any ideas why?

blah = 0
randgen = System.Random()
highnum = 0.0

Message-ID: <1DFB396200705E46B5338CA4B2E25BDE9E7C23@DF-BANDIT-MSG.exchange.corp.microsoft.com>

I can make some fairly small changes to this test and find that
IronPython is about 1.3x faster than CPython on roughly the same code.
The fact that I need to make changes is obviously not a good thing.
However, the changes that I made help show the kinds of rough edges we
have left before getting to IronPython 1.0.  Here are the four issues I
found while playing with your program.

1. We're rapidly increasing the number of standard CPython modules that
run in IronPython, but we're probably not making it clear enough to
folks how to use them.  I use the following tiny site.py file so that I
can import from the standard CPython Lib:
---- site.py ----
import sys
sys.path.append('c://Python24//Lib')
-----------------
The random module is working in the IronPython 0.9.2 and later, so if
you drop in this site.py, your CPy version will run just fine in
IronPython.

2. The first thing you'll notice if you do that is that the numbers look
horrible.  IronPython appears to be about 8 orders of magnitude slower
than CPython.  This is a stupid and outrageous bug in time.time which
we'll fix where it's reporting 100 nanosecond ticks as seconds.  For
now, you should use time.clock instead which will work correctly on both
systems.

3. The next issue is that the max builtin in IronPython is horribly
slow.  It's more than 25x slower than the max in CPython.  This is the
primary cause of your slow-down.  We need to fix this.  The reason for
the slow-down is that max has an overload which accepts a params
object[] (the Python equivalent of *args) and we wind up going through
an extremely slow method dispatch path to figure out which overload of
max to call.  This is more work than fixing time.time, but not that
much.  The work-around for now is to define a fast_max function in
Python.

4. After fixing the perf issue with max, I find that IronPython is still
about 1.6x slower than CPython running this test.  This final
performance hit turns out to come from random.random.  This is another
case of a slow path where IronPython doesn't do so well looking up
members on external modules.  CPython isn't lightning fast at this
either, and you can speed up both implementations by putting
random.random into a variable called rand.  We'll be fixing this too,
but these kinds of slow-downs are obviously of a lower priority than the
jaw-dropping 25x one you found for max.

After the changes above, IronPython on my box is about 1.3x faster than
CPython.

#1 and 2 are simple fixes.
#3 and 4 will require bigger fixes, but these are the kinds of things
we're addressing for IronPython 1.0.

Here's my final version of the code with the changes mentioned above,
plus a few small changes to make the timing and reporting a little
friendlier by running for more iterations and collecting the stop time
before printing anything.
-----------------------------
import time
import random

def fast_max(x,y):
    if x > y: return x
    else: return y

kTotalReps = 8000
kNumReps = 100

start = time.clock()
blah = 0
highnum = 0.0
rand = random.random
for i in range(kTotalReps):
	myt = []
	for j in range(kNumReps):
		toadd = rand()
		myt.append(toadd)
		highnum = fast_max(highnum, toadd)
		blah = blah + 1

end = time.clock()
print highnum
print '%.3f seconds for %d iterations' % (end-start, blah)
-------------------------------

Thanks for the entertaining example - Jim

Hi,

I am familiar with python but not with .NET. I also do not know any other
programming language like C# and VB so following tutorials can be difficult.
What steps should I take to start learning how to use ironpython?

Thank You.

Message-ID: <1DFB396200705E46B5338CA4B2E25BDE9E7F05@DF-BANDIT-MSG.exchange.corp.microsoft.com>

Hello IronPython community,
 
today, we have released IronPython 0.9.3. The biggest change for the
release is the implementation of closures and re-factoring of the
name-tables. The closures were becoming the limitation of IronPython
that we were coming across more and more often when working on the
regression test suite. Most of the bugs fixed are closure related, but
there are few others that we fixed:
 
* Closures and closure related changes:
 - Name is resolved to object in enclosing scope, even though it is
defined in the current scope (later)
 - Closures are broken
 - self not known in definition of lambda function
 - self not known in lambda function
 
* Generator releated bugfixes:
 - CodeGen for nested generators throws in some cases
 - Re-generating code with generators throws
    - codegen for generators modified state of AST which would cause
exceptions on 2nd pass

 
* True/False issue
 - comparison code didn't handle boolean type properly. For example True
== False didn't return False
 
* Changes in import statement name binding
 - rework of import statement. import binds to local names rather than
global ones
 
* Old type class doesn't have __dict__
* FastEval option doesn't resolve builtin names

Our thans for feedback and bug reports go to: Jacques de Hooge, Jonathan
Jacobs, Sumit Basu and Szymon Kobalczyk

0.9.3 is a big improvement.

The closures really make my code a lot more compact and readable.

I am impressed by the speed of progress on IronPython.

 

After a few months of development using the combination of IronPython and
WinForms I've grown addicted.

Has been a long time since programming was so much fun!

You can either use the CPython libraries, or instead of "os" use the
"nt" module which IronPython contains.

You can either use the CPython libraries, or instead of "os" use the "nt"
module which IronPython contains.

Hi Guys,

          I was testing out Iron Python and I was trying to test out the OS
module but I got the error ..

 

TraceBack (most recent call last)

            At <shell>

ImportError: No module named os..

Obviously it doesn't exist. Thus is there any means to get around this?

In standard Python, os is not a built-in module, however, nt module is
built-in. IronPython includes built-in nt moduel (as built-in module
implemented in c#), but not the os. module.
 
I am not understanding your question about the IO module. There is no
"io" module in neither CPython nor IronPython:
 
Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on

Hmm, I tend to disagree with you on the fact that in standard python os is
not a built in module. Even though nt is built in, the os modules also built
in. But what is confusing is that Anthony posted that he was able to import
the os module like so.

 

Anthony's post..

Double check your setup, since here is what I get importing os:

IronPython 0.9.3 on .NET 2.0.50215.44
Copyright (c) Microsoft Corporation. All rights reserved.
>>> import os
>>> dir(os)
['AttributeError', 'Equals', 'False', 'GetHashCode', 'GetType',

'__builtins__

'removedirs', 'r
enames', 'sep', 'spawnl', 'stat', 'stat_result', 'sys', 'unlink', 'waitpid',
'wa
lk']
>>>

 

He said it had something to do with my set up. Anyway, in terms of the os
module in standard python I could do something like so.

 

Import os

 

doesFileExist = os.path.isdir(FileName)

if(doesFileExist):

      print FileName

else:

     print 'No file'

 

In terms of using the nt module, how would I implement this?

Define 'builtin'.
(define 'sex' ;-)

>From cpython's help utility..

Help on built-in module sys:

NAME
    sys

FILE
    (built-in)

Help on module os:

NAME
    os - OS routines for Mac, DOS, NT, or Posix depending on what system
we're on.

FILE
    /usr/lib/python2.3/os.py

os.py == not builtin

I often describe the "help" utility as "built in."
really, it is not.. it is a standard part of python.. but it is written as a
python module, not a core part of the interpreter written in pure C. 

The help facility, which I use all the time in cpython, and semantically
consider a builtin, is *not* technically a builtin. It comes from pydoc.py.
Which rocks. But is not built in.

cheers 

Drew

Anthony is probably making use of site.py (which can be found in 
<path_to_ironpython>\bin\Lib) to make the Python stdlib accessible to 
IronPython. (That is, unless I'm mistaken.)

Jim mentions[1] a short site.py in one of his recent emails which is 
probably just what you're looking for.

Hope this helps.

. the quick answer for getting started with ironpython
is to get started with zope`s python for .NET
[@] http://www.zope.org/Members/Brian/PythonNet/readme.html#getting_started

. ironpython is at microsoft and it is alpha;
so, there may not be a lot of help besides knowing that
iron python is just python for another platform (lots of help for python)
. an easier approach might come from zope; [@]
http://www.zope.org/Members/Brian/PythonNet
but, this appears to have a problem with python`s exceptions being old-style
classes, instead of new-style classes that don't have to subclass Python's
Exception class,
although Py'NET`s author is under the impression that the
next version of Python might change for .NET compatability
. I'm personally putting my bets on pypy [@]
http://codespeak.net/pypy/dist/pypy/doc/index.html
. not only is pypy getting european funding for being fork-friendly (it`s

Python for .NET 1.0 beta 5 is based on Python 2.4

http://www.zope.org/Members/Brian/PythonNet/Releases/PythonNet-1.0-beta5.tgz<file:///Members/Brian/PythonNet/Releases/PythonNet-1.0-beta5.tgz>

"(. zope`s package does *not* produce managed code (IL) from Python code
. Rather, it is an integration of the C Python engine with the .NET runtime
. This approach allows you to use the CLR services
and continue to use existing Python C extensions
while maintaining native execution speeds for Python code. )

<file:///Members/Brian/PythonNet/Releases/PythonNet-1.0-beta5.tgz>
 *Why Python For .NET?*

Python for .NET gives Python programmers near-seamless integration
with the .NET Common Language Runtime (CLR)
and provides a powerful tool for application scripting for .NET developers
. Using this package you can script CLR applications
or build entire applications in Python,
using CLR services and components written in any language that targets the
CLR
(Managed C++, C#, VB, JScript, etc.).

 Is This Like Jython for .NET?

Not really. Jython provides an implementation of the Python language and
runtime engine in pure Java. Python for .NET is not a re-implementation of
Python, just an integration of the existing CPython runtime with .NET.

While a solution like Jython provides "two-way" interoperability, this
package only provides "one-way" integration. Meaning, while Python can use
types and services implemented in .NET, managed code cannot generally use
classes implemented in Python.

A Jython-like solution for .NET would certainly be doable and useful - but
it would also require far more work than the current approach.
 Is This Related To ActiveState's Python.NET Work?

No. That effort focused on the feasibility of making Python a true .NET
language (compiling Python to IL). You can find that work as well as a paper
describing the goals and results at http://www.activestate.com.

**Does it work with Mono?**

Preliminary testing shows that PythonNet will run under mono, though the
test suite fails quickly due to NotImplemented errors raised in parts of
the Mono runtime. The PythonNet integration layer is 100% managed code,
so there are no long-term issues under mono - it should work better and
better as the mono platform matures.

It is not currently possible to *build* PythonNet using only the Mono
tools, due to an issue involving the Mono assembler / disassembler. You
should, however, be able to try the pre-built assembly under Mono (or
compile it yourself with the MS tools and run it under Mono).

Note that if you are running under Mono on a *nix system, you will need
to have Python 2.4 installed. You will probably also have to make a
symlink in the PythonNet directory pointing to the
libpython2.4.so<http://libpython2.4.so>on
your system. You will need to name the symlink 'python24.so'.


**What is the current status of the package?**

The Python for .NET runtime is quite stable and is nearly feature
complete. There are a large number of unit tests as well as a number
of stress tests, leak tests and demo scripts. There are still
some loose ends to finish up for the 1.0 release, but it is definitely
usable for real applications.

Current issues:

- Managed exceptions are not integrated well with Python exceptions, due
to Python's insistence that exceptions must be old-style classes. Not
sure if there is a sneaky way around it, other than lobbying Guido to
look at it for a future Python version. Currently, it looks like
Python 2.5 will support new-style classes as exceptions.

- Packaging is still pretty minimal. There should probably be an msi
installer etc. for win32.


[*]distr`doc/todo:

ToDo List:

- incorporate fxcop suggestions

- out, ref params
-

- Fix anything that relies on member order in reflection - this will
change post 1.1

- Support out and in/out params

- fix loss of python wrapped instances when handed over to clr

- Finish leaktest.py and finish checking for leaks.

- Implement class wrappers to allow Python code to implement interfaces
and abstract .NET classes

- Finish basic embedding APIs & tests

- Integrate nunit 2

- Test thread state management & async delegates

- Tests for overload selection

- Cached type in TypeManager need to be cleaned up on managed
runtime finalization (low priority); review finalization
generally.

- Pester Guido about letting exceptions be new-style classes that
don't have to subclass Python's Exception class :) See if there is
some sneaky way around it.

- Look at optimizing some type conversions

- document loading specific versions of assemblies




 llvm tip (Execution Engine-independent JIT compilers)
[@] http://blogs.msdn.com/michaljc/
 <http://blogs.msdn.com/michaljc/archive/2005/02/23/379329.aspx>

I have recently put together a set of slides about LIL (Low-level
Intermediate Language) and gave a talk at Microsoft. This work was done
before I joined Microsoft: LIL was developed by the ORP (Open Runtime
Platform<http://www.intel.com/technology/itj/2003/volume07issue01/art01_orp/p01_abstract.htm>)
team at Intel. LIL was addressing multiple issues in the ORP design (papers
referenced below can give you an idea) but the focus of this presentation
was more narrow: how to improve the interface between the JIT (Just-In-Time
compiler) and the rest of the VM. I'd like to point out that I use the terms
VM (Virtual Machine) and EE (Execution Engine) interchangeably (see this
post <http://blogs.msdn.com/brada/archive/2005/01/12/351958.aspx> for a
discussion of this terminology). Others have come up independently with
somewhat similar ideas and I found quite a lot of interest in the LIL
approach in conversations both inside and outside of Microsoft. For my
current presentation I took some of the old LIL slides that I used in a talk
I gave at ETH Z?rich <http://www.inf.ethz.ch/> in 2003 and modified them to
focus on the JIT/EE interface. This version of slides benefited from my
conversations with many people in the last year, after the original LIL
papers were published. I think that I owe most to my conversations with
George Bosworth and to comments by Thorsten
Brunklaus<http://www.ps.uni-sb.de/%7Ebruni>who worked on the SEAM VM
(see below) and now is in the CLR team.

LIL is described at length in the VM'04
paper<http://www.usenix.org/events/vm04/tech/glew.html>.
The MPOOL'03 paper
(pdf<http://www.cierniak.org/research/publications/orp-mpool-2003-final.pdf>)
presents some thoughts on how LIL could be used to abstract away the object
model from the JIT. Full references to these two papers are available on my
publications page <http://www.cierniak.org/research/publications>.

The talk I just gave had the title "*Execution Engine-independent JIT
compilers*" and the basic idea is that LIL enables a much better abstraction
of the EE from a JIT's point of view then what is used in all known to me
implementations of virtual machines for JVM and CLR/CLI. I made the full
presentation available as a pdf
file<http://www.cierniak.org/research/publications/lil-msr-talk-2005.pdf>
.

Anthony's post..

Double check your setup, since here is what I get importing os:

He said it had something to do with my set up. Anyway, in terms of the os
module in standard python I could do something like so.

 

Import os

 

doesFileExist = os.path.isdir(FileName)

if(doesFileExist):

      print FileName

else:

     print 'No file'

 

In terms of using the nt module, how would I implement this?

In standard Python, os is not a built-in module, however, nt module is
built-in. IronPython includes built-in nt moduel (as built-in module
implemented in c#), but not the os. module.

 

I am not understanding your question about the IO module. There is no "io"
module in neither CPython nor IronPython:

 

Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on

You can either use the CPython libraries, or instead of "os" use the "nt"
module which IronPython contains.

Hi Guys,

          I was testing out Iron Python and I was trying to test out the OS
module but I got the error ..

Obviously it doesn't exist. Thus is there any means to get around this?

Hi People,

 

I have just joined to the list. 

 

I have downloaded the Iron Python but don't know where to start. Is there a
beginner's web site somewhere?

I am just making a wild guess here, but do you have the Windows

If not, you can get it at:

WindowsBase is a part of WinFX and should be in your GAC if you've installed at least the Sep CTP runtime components as per Martin's posted link.

Thanks Greg!!

I had install Avalon as a pre-requisite for Microsoft Max but haven yet 
come around to playing with this new API. Thank you for getting me half 
way into it with this simple app.

Cool!!

Subject: [IronPython]  Scripting use with security pointers wanted
In-Reply-To: <43583E60.50605@gmail.com>
Message-ID: <200510230601.j9N61f7a024833@mac.com>

I would like to use IronPython for scripting, but that poses large security
concerns.
Any pointers would be welcome.

1) How to run the scripting code in a secure manner, but give it access to
the public API needed to script the application.
2) How do I run IronPython code in a separate AppDomain?
3) How do I give that other app domain restricted access to my API?
4) How do I set it up so the app domain is running with low security
privileges?

Most of this is not specific to IronPython, but hopefully someone here has
done this already.  It would be great if there were a standard module/method
for doing this out of the box.  I could see having a generic class
IronPythonScript<API> that takes an API type and results in an object that
manages the other app domain, and exposes an interface for loading and
executing scripts, while providing an object of the API type to the scripts
as a point of interface with the application.

.Net has a notion called "code access security" that allows you to control what your code is able to do when called by someone else (and many other things).  If you Google for "code access security" ".net" --

http://www.google.com/search?hl=en&lr=&q=%22code+access+security%22+%22.net%22

you'll see many pointers to discussions, documentation, and code samples.

It should not be necessary to use another AppDomain to get the security you want.  The only real advantage of using another AppDomain is that malicious code can cause a "denial of service" problem by misbehaving if it runs in the same AppDomain as your app; if the code is running in its own AppDomain, it won't affect things permanently because you can deal with it being non-responsive by shooting the other AppDomain.

However, there are some restrictions on what can be done across AppDomains (related to the requirement that data be "marshalled" across the AppDomain boundary), and everything is (somewhat) slower than would be the case if everything's within the same AppDomain.

Good luck...

Generally we do advocate creating a separate AppDomain for different trust levels -- trying to ensure that each AppDomain has at most two trust levels, FullTrust and one partial trust set.  The reasoning is that any assembly in an AppDomain can access any other assembly loaded into the domain.  Which means it is generally trivial for an assembly running at a low trust level to elevate its trust to a higher level by routing its calls via an assembly at a higher trust level.  While FullTrust code is often audited for security when being called by partially trusted code, partial trust assemblies are generally not.

That being said, seeing what it would take to get IronPython to run partial trust has been something I've been meaning to investigate for a while now -- its just been on the back burner.  The actual Python engine itself will require FullTrust because IronMath.dll contains some unverifiable code.  However that should not be a problem, as long as you can coerce the code generated for the Python scripts to run partial trust.

That's where the issue lies -- since IronPython is using lightweight code gen, the code generated from the script runs in the same security context as the assembly it was emitted into -- in this case the fully trusted IronPython.dll

In addition to partial trust issues, there is the possibility of marshalling issues that were pointed out previously in this thread.  I imagine this will be a bit of an uphill battle at first, however a good start would be to recompile IronPython with a strong name, and use the new Simple Sandboxing API (http://blogs.msdn.com/shawnfa/archive/2005/08/08/449050.aspx) to create a partial trust sandbox that granted FullTrust to IronMath, and partial trust to IronPython to work around the above issue.  Then some trial and error will be needed to see how well the Python engine works in partial trust.

Thanks for the pointers.  I want to make sure my scriptable app is not
creating security holes like ActiveX created in the past with full trust
loaded content.  At the same time there are aspects I would like to
implement that require good performance.  Using a general purpose language
for app extension may be part of the issue.  What I want is a language that
can be used to add custom behavior to the app, but I want to restrict what
that behavior can do to the public API my app exposes.  At the same time,
letting add-ons do advanced things can make the infrastructure much more
adaptable and usable in the market.  It is not practical to marshal the app
data to another app domain, it might be reasonable to marshal action objects
from the extension app domain to the application.  This ensures that only
approved actions execute in the application domain.  But, then only those
actions can affect the application.  Either the actions need to be very
basic and general (property access, etc), or the custom logic needs to
execute in the application domain.  I guess it really comes down to how much
overhead is there for each API call to marshal an action object between app
domains.

I think this is going to require some experimentation to resolve.

Hi. I am new to the list, and I am not sure this is the right place to report issues.

Just in case, 2 issues:

- %i appeared as not supported. I had to replace it by %d (in a format expression)
- splitlines appeared as not supported. I had to replace it by split('\n')

They are not big deal, but for real projects changing others code to meet my compiler
could not be an option....

Byebye, P.


ps: by the way, the code performed more than 2 times slower than running standard 
python... I am pretty much a dotnet fan, so I'd love running my code under .net.... so feel 
free to ask me for the code in case you need performance cases to tune the thing better....

Subject: [IronPython] IronPython and WPF .. too cool
Message-ID: <b6f3249e0510290639m66aeb397s89c87e8705a66eb6@mail.gmail.com>

Hi all,

I'd just to like take a wee moment to say "Hi", first post etc. After
hearing rumours about IronPython, I decided to actually find out what
the fuss about the whole .NET thing was, and IronPython seemed the
perfect way.

Must say, very impressed with the .NET shebang, and how simply
IronPython works with it.
It's great to learn a new framework while remaining within my comfort
zone, as I've only been coding a year, and solely in Python.

As of finding this advice from Jim Hugunin in the list's archive:
---- site.py ----
import sys
sys.path.append('c://Python24//Lib')
-----------------

I am a very happy panda. Anyway, I was responding to the above post,
and I'd like to say thank you to the OP. I downloaded and had a look
at WFP/Avalon, or whatever it's properly called, and wow. Awesome.
Kudos to MS for a coherent and what looks to be incredibly powerful
GUI API. From my Python background I can only describe it as the ease
of use of Tkinter with the power of wxPython, although it'd probably
be better to say it's easier to use than Tkinter, and more powerful
than wxPython on a Win32 platform.

Out of curiosity, are there any docs for it yet? I managed to find
some brief introductions and a hitch-hiker's guide on MSDN... but with
some assumptions (and I'm also pleasantly surprised that WFP is quite
intuitive) and use of Reflector(www.aisto.com/roeder/dotnet/) I
managed to tweak a few things here and there, so I thought I'd post
them up for general consumption if there isn't any docs yet.

To change the font of the TextBlock -

txtElement.Text            = "Look Ma, it's Courier New"
txtElement.FontFamily   = FontFamily("Courier New")  #or other installed font

And to add an icon or tooltip -

mainWindow.Icon 		 =   IconData("c:/games/RA2/RA2.ico")
mainWindow.ToolTip 		= "Yes, it's the Red Alert 2 icon..."

I think there's more than one way to specify the icon, but I chose the
simplest.
There's a whole bunch of other font stuff too, FontStyle etc.

I also ran a dir() on the textblock, panel, and window objects, and
between them there's about 1500 attributes, but it's good to have a
browse and find a point to start guessing from.

Regards,

Liam Clarke

Hi People,

 

I have just joined to the list. 

 

I have downloaded the Iron Python but don't know where to start. Is there a
beginner's web site somewhere?

Hi Guys,

          I was testing out Iron Python and I was trying to test out the OS
module but I got the error ..

 

TraceBack (most recent call last)

            At <shell>

ImportError: No module named os..

 

Obviously it doesn't exist. Thus is there any means to get around this?

Hi,

I am familiar with python but not with .NET. I also do not know other 
programming languages like VB or C# so it is not that easy to follow 
tutorials. What should be my first step to learn to use ironpython?

Thank You.

You can set sys.path to point to CPython's Lib directory which includes os module:

>>> import sys
>>> sys.path.append("C:\\Python24\Lib")
>>> import os
>>> os.name
'nt'

You can even put the first 2 lines into your site.py (located in IronPython's Bin\lib directory)

Martin

IronPython is not quite "finished" so your best bet would be to go through the Python tutorial at www.python.org first. Then you will understand what is happening with regular Python and be in better shape to deal with what is and what is not finished or working in IronPython.

I am in a similar boat with regard to knowing some Python but very
little .NET.  I'm very intrigued by the ability to access the .NET
framework from Python, but I know so little about .NET I'm not even sure
what question(s) to ask.

>From what I have seen in the examples and archives, it looks like there
are two basic ways to get at the .NET code: LoadAssemblyByName and
LoadAssemblyFromFile.  My problem is that I don't know how to correlate
between the assembly names or file names and the .NET APIs I read about.

Is there somewhere I can look on MSDN or in a manual or in Visual Studio
that will tell me if I want to access 'X' .NET feature then the assembly
name is 'Y' or the file name is 'Z'?  I think I must be searching for
the wrong terms or something.

Thanks,

Sure -- you just have to go to the MSDN docs for the class you're using.  For instance, if you want to use the System.Security.Cryptography.SignedXml.ComputeSignature() method, you would go to the MSDN documentation for "SignedXml Class" (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemsecuritycryptographyxmlsignedxmlclasstopic.asp) and then at the bottom of the page, in the requirements section is:

Assembly: System.Security (in System.Security.dll)

Following up the improving the experience for new .Net users, IronPython could provide specialized commands to search msdn and pop up a internet window. For example something like

    msdn "System.Security.Cryptography.SignedXml.ComputeSignature"   // search based on literal
    msdn foo    // search based on the object type

For instance, if you want to use the System.Security.Cryptography.SignedXml.ComputeSignature() method, you would go to the MSDN documentation for "SignedXml Class" (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemsecuritycryptographyxmlsignedxmlclasstopic.asp) and then at the bottom of the page, in the requirements section is:

Assembly: System.Security (in System.Security.dll)

I am in a similar boat with regard to knowing some Python but very
little .NET.  I'm very intrigued by the ability to access the .NET
framework from Python, but I know so little about .NET I'm not even sure
what question(s) to ask.

LoadAssemblyFromFile.  My problem is that I don't know how to correlate

Is there somewhere I can look on MSDN or in a manual or in Visual Studio
that will tell me if I want to access 'X' .NET feature then the assembly
name is 'Y' or the file name is 'Z'?  I think I must be searching for
the wrong terms or something.

Hi,

I am familiar with python but not with .NET. I also do not know other
programming languages like VB or C# so it is not that easy to follow
tutorials. What should be my first step to learn to use ironpython?

Thank You.

Pretty easily done with a quick script:

import sys
sys.LoadAssemblyByName("System")
from System import String
from System.Diagnostics import Process

def msdn(query):
            if query.GetType() == String.Empty.GetType():
                        Process.Start("http://search.microsoft.com/search/results.aspx?View=msdn&st=b&c=4&s=1&swc=4&qu=" + query)
            else:
                        msdn(query.GetType().FullName)

Will launch the MSDN help page in the user's default browser.  I'm not sure if there's a nicer way to determine if the parameter is a string or not, and this also relies on the fact that the browser will normalize the query string (if it contains a space for instance) ... but will break if you query contains the & character.

Is there a plan to add a WinForms console control in the IronPython? I stumboled on this problem last week and it is suprisingly hard to get a winform control to act as a console app!
