[IronPython] ipy in Emacs with TabCompletion

Re: [IronPython] IDE status info

[J. Merrill]

I am not affiliated with the company or product I'm about to discuss in any 
way; I have not purchased it myself.

For those who are discouraged by the need to have a version of Visual Studio 
that costs money (as the Express version doesn't support plug-ins) in order to 
get IronPython integration with a commercial-quality IDE, there is a cheaper 
alternative than purchasing the full Visual Studio.

The company RemObjects has built Chrome -- a .NET-only compiler for the Delphi 
language (aka Object Pascal), and they've made a number of enhancements to it 
to better support .NET concepts.  (In many ways it compares to Delphi like 
IronPython compares to CPython.  Do not expect VCL support, however.)  The 
command-line version of the compiler is free to download, and is available for 
Mono as well as for Windows.  What they sell is the integration of Chrome into 
the Visual Studio IDE (and other products unrelated to Chrome); they have a 
"student / non-commercial academic" version for [as of today] EUR 49.

Until recently, you had to own VS to use Chrome's IDE integration.  They have 
now made it possible to buy "Chrome for Visual Studio" as before, or you can 
buy "Chrome with Visual Studio" (Chrome inside a copy of VS) for about EUR 50 
more (EUR 26 more for student version).  It is my impression that you will be 
able to plug IronPython into that version of VS, as they discuss on their site 
the value of being able to use 3rd-party plug-ins for VS in conjunction with 
Chrome.  You can see the prices at
http://www.remobjects.com/order/
Scroll down past the subscriptions and suites (averting your eyes from the 
prices on the right, lest yee be scared off!) until you get to the Chrome 
section.  Also, Delphi users get a price break.

My apologies if anyone thinks this is an inappropriate post; I'm just trying to 
help those with small wallets get a good IDE for IronPython -- and there's 
little wrong with Chrome for those (Delphi users) who already have their heads 
around Object Pascal.

[IronPython] Passing Arguments in hosted enviroment

[Bernd Rössl]

Title: Passing Arguments in hosted enviroment







Hello list,


Great to see 1.0 prod. Is out :)


Anyway, currently i'm embedding ironpython to a web application. This gives us the ability to write extension and modules in python. One requirement is the possibility to pass arguments from the user context to the python enviroment. Till now i've done this by adding or setting object to the globals. Unfortunetly this approach isn't multi user suitable since the python enviroment is static and the same instance for all users respectivly for all sessions. So it could happen that a passed value of session2 overrides the passed value of session1.

My thoughts:


1. Each session has it's own python enviroment: this results in higher memory usage and needs time each time a session loads it's python enviroment

2. The arguments are not passed directly to the enviroment but to a session dependent object: each script has to take care what args of what session will be taken

3. ? Is there a possibility to pass args to a "ExecuteFile" context? I mean my hosting application call's the method "executeFile" each time a script will be executed and the passed args should be reachable ONLY in this execution. 

What is the best solution to handle this challenge?


Thanks for your hint's!


Regards, bernd

[IronPython] xmlrpclib example

[Sanghyeon Seo]

Python has a great xmlrpclib module to do XML-RPC as part of its
standard library:
http://docs.python.org/lib/module-xmlrpclib.html

Today I tried it with IronPython and it just worked.

You need to be able to load Python standard libraries. In addition,
you need pyexpat.py I wrote:
http://sparcs.kaist.ac.kr/~tinuviel/fepy/lib/pyexpat.py

An example code is here. It should print "Alabama".

[IronPython] CherryPy on IronPython update

[Sanghyeon Seo]

This post updates:
http://lists.ironpython.com/pipermail/users-ironpython.com/2006-May/002254.html

Summary: it's still flaky. At least on Mono, it randomly segfaults.
However, the patch is much shorter.

Files are available on the same place:
http://sparcs.kaist.ac.kr/~tinuviel/fepy/ironcherry/

My test environment is now Mono 1.1.17.1 and IronPython 1.0 Production.

Changes since Beta 6:
* patch-lib, a patch to inspect.py is needed no more. Mono bug on
GetEncodings() which it avoids is long fixed.
* IronPython's comparison bug involving None is long fixed.
* IronPython now has datetime.datetime class. Reverted patch on
timestamping code and sessionfilter.
* gzipfilter patch and cptools eval patch remains.

Current status:
