Sure, use a post that was a response to a question I already asked :-)

Thanks, it was a good refresher on the modules stuff.

That helped a ton, thanks for that! It IS much easier than I was thinking it
had to be. I had been looking at all the exception stuff in the IronPython
sources and some of the stuff that goes on in there is pretty crazy.

Thanks again,

Re: [IronPython] Adding Unit Tests

I've got a pull request
waiting that at least
gets the TestRunner to run. It fixes up some bugs and
disables some tests in the configuration file where missing directories
caused it to crash.

As long as all of the tests we want to run keep running there's no reason to 
keep
TestRunner - it was just a way to run all of the same tests we ran before w/o
relying upon internal MS infrastructure.

I'm not sure how many of the DLR tests we'll still want to run but I imagine we 
can
just wrap them in unittest and have it run the EXEs.

I don't think there is. It's not too bad once you figure it out, but
figuring it out is tricky, to say the least.

You could look at
https://bitbucket.org/jdhardy/ironpython.sqlite/src/95894443fffe/src/Exceptions.cs,
which has it all in one place for a fairly deep exception hierarchy.
(`InitModuleExceptions` is called from `PerformModuleReload` in
_sqlite.cs.) I just figured that out from reading the existing
modules, but I'm thinking I should write a "module implementer's
guide" with those sorts of lore in it. I thought there was one
started, but now I can't find it.

So is there any value whatsoever in keeping the TestRunner around? If
there isn't, I'll look into porting the IronPython test infrastructure
to use unittest.

IronRuby doesn't use the test runner. IronRuby's harness is written in Ruby 
(Languages\Ruby\Tests\Scripts\irtests.rb). It's run by a previous IronRuby 
version checked in to Util\IronRuby.

Maybe we should just use unittest2 as the test runner, and wire it into the 
existing one if the IronRuby guys want to keep using it.
Besides, I hear Michael knows a little bit about unittest2, so he might be able 
to help.

Re: [IronPython] Adding Unit Tests

2011-01-11 Thread Vernon Cole 
An interesting thought...
 MY Linux box has a cmd.exe -- it's part of WINE.
But cmd.exe is a very simple shell.  How hard would it be to write one in
Python? IPython (different from IronPython) IS a shell, if I understand
correctly.

[IronPython] Exception Model for modules implemented in C#

2011-01-11 Thread Slide 
Is there a document that describes how to implement a Python exception in a
C# module? In looking through the code, the exception stuff is seemingly in
about 20 different places and bringing it all together is not easy, at least
to the casual observer :-)

Thanks,

[IronPython] Referenced Assemblies with DLR languages

2011-01-11 Thread Doug Blank 
Two questions about referenced assemblies (which are really perhaps
DLR questions):

1) I'd like to be able to use different names than are used in a DLL.
For example, say I have a Library.dll, and it has a class
"ReallyBadName". Is there an easy way that I can rename or alias
ReallyBadName after I add a reference to Library? I'd like this to
work for all of my DLR languages, so I'd like to do it right after I
add the reference, rather than, say, doing it in Python with "import
ReallyBadName as GoodName"---but that is the effect I want.

2) Is there a way that I could have a Library.dll bring in other
assemblies so that they would be available to DLR languages? Of
course, one could load an assembly in an assembly that you
clr.AddReference, but that wouldn't make it available to all of the
DLR languages right? It seems that one would need a callback where the
clr was passed into the assembly which was clr.AddReference-ed, so
that it could add references too. Could I overload the clr importer to
do that? Or is there a better way?

Thanks for any pointers,

-Doug
