Created Issue: eval() function doesn't work as expected [33083]

sky_handsome — Wed, 29 Aug 2012 22:39:36 GMT

The following simple code will raise exception:
f = lambda: x + 1
print eval(f.func_code, {'x': 2})

NameError: global name 'x' is not defined

while using python will successfully print the result.

I'm writing a C# application that can be extended via IronPython scripts. These scripts can access a library of .NET classes I wrote in C#.

Those classes have some public methods and properties that I would like to hide from the IronPython scripts, so that a script can't call them. Looking at the IronPython source code, I noticed the PythonHidden attribute in IronPython.Runtime that seems to do just that. However, that attribute is internal, so there is no way for me to use it in my own classes.

Is there a reason for PythonHiddenAttribute being internal? Can it be made public? Or is there another way to hide members from IronPython that I just missed?

I didn't even realize it was internal, and I see no reason to keep it that way.

Commented Issue: IronPython 2.6 not finding a .pyc file. [33067]

MarkusSchaber — Mon, 27 Aug 2012 07:11:56 GMT

I'm very new to IronPython. I was able to download v2.6 and call some basic functions from C#. The problem I have is that one function imports a .pyc module provided by a third-party. So there is no .py available.

Is there a solution for IronPython to work with modules ( .py ) that references another module that is .pyc format? If so, could you provide how to?

Thanks in advance.
Comments: ** Comment from web user: MarkusSchaber **

pyc files are implementation version dependent - even cPython does not allow pyc files to be re-used across different versions.

I am looking at supporting byte code execution for a future version.

If you use a search engine, you can find various options to try. For example, I found

ironpython does not currently support pyc files.

I am new to IronPython and was wondering if a Windows Form GUI is available. I have installed the latest version of IronPython and am using Visual Studion 2010. I can hard code windows forms properties but I don't see an interactive window that I am used to with .net.

Closed Issue: still can't install setuptools/distribute/pip under IronPython 2.7.3 [33004]

slide_o_mix — Thu, 09 Aug 2012 09:41:28 GMT

Hello,

it's still not possible to install setuptools or distribute under IronPython 2.7.3, thus preventing the installation or use of pip to easily install Python packages.

1/ installing distribute per http://pypi.python.org/pypi/distribute/#installation-instructions:

C:\Program Files (x86)\IronPython 2.7>ipy64.exe C:\Users\xxx\AppData\Local\Temp\distribute_setup.py

See the error message above.

2/ installing setuptools, from IronPython directory:

I re-installed IronPython from scratch, ran ez_setup then have been able to install distribute and pip.

Thanks ! :-)
