[IronPython] Compiling IronPythonConsole.exe

Thu May 7 18:31:12 CEST 2009

What you’re attempting to do here is define overridden properties for the methods on the IConsole interface.  IConsole itself isn’t very well documented but the there’s info on properties here: http://www.ironpython.info/index.php/Overridable_Properties

I do realize you’re just trying to get someone else’s stuff to work.  If you want an experience that just works my guess is that you could use IronPython 1.x which readline probably works with.  But making something new work is always more fun! ☺

Where can I find the docs on this

I am not the best coder but maybe the documentation will help me to understand what your saying

*cheers

What I understand I need to create the function "get_Output" "set_Output" etc but in order for them to return the values would it be

def set_Output():
       set_Output

Anyway once again thank you

btw it isn't my code its a IronPython module I need to work :-)

Ahh, I see, there’s new properties on IConsole to get/set the Output/ErrorOutput TextWriters.  You can define get_Output/set_Output/get_ErrorOutput/set_ErrorOutput methods to implement them for the interface on IronPythonWrapper.

They can simply save/return the values and you can ignore it or you can use the TextWriter to pick up when the user redirects sys.stdout/sys.stderr.

hmm I did a search through the code there is no set_Output and I searched Output and set_ as separate search nothing... Now I am confused

Anyway I really appreciate your help :-)

Is there an actual call to a “something.set_Output(…)” method somewhere in the code?

If so it should be “something.Output = ….” – in 2.0 we no longer allow calling properties

via the property methods.

Well I am about ready to give up for the night anyway here is my last error :-)

The last line should probably be:

cmdLine.Run(Python.CreateEngine(), IronPythonWrapper(), PythonConsoleOptions())

I thought IronPythonWrapper was an instance but it looks like it’s a type – so it needs to be constructed.

Hello Ive tried implementing what you suggested with no success

I have attached the source just in case you or anyone can shed some light on it

Cheers

This one’s a little more complex.  It looks like there’s no longer a writable IConsole property.  Instead it looks like you need to create a PythonCommandLine object and then pass in a ScriptEngine, an IConsole, and a ConsoleOptions object.  That’d look something like:

import clr

clr.AddReference(‘IronPython’)

clr.AddReference(‘Microsoft.Scripting’)

from IronPython.Hosting import PythonCommandLine, PythonConsoleOptions, Python

cmdLine = PythonCommandLine()

cmdLine.Run(Python.CreateEngine(), IronPythonWrapper, PythonConsoleOptions())

When you call Run here that will then start the interactive interpreter loop – I’m not sure if that’s exactly what you want.  This is also going to create a 2nd IronPython engine because you can’t really get to the current ScriptEngine from within IronPython itself – again there could be reasons why you wouldn’t want this to happen.

If you’ve got suggestions on what you’d like the APIs to look like for this scenario let us know ☺

Hello

pyreadline plays an important part in scapy (http://www.secdev.org/projects/scapy/) which is what I am porting to IronPython. My reason for this is well I like a challenge. That's the only reason as self serving as that may seem :-P

Thats the result of my console

Welcome to Scapy (1.2.0.2-win)
☺←[34m←[1m☻>>> ☺←[0m☻

I am not 100 % sure I implented this line correct

"MyConsole = IronPythonWrapper()"

which was previously

IronPythonConsole.PythonCommandLine.MyConsole = IronPythonWrapper()

maybe more experienced people can shed a light on this

when that is solved I can submit a patch :-) I would be happy to

Hey Stephen thank you

You solved my problem (I had copied pyreadline from previously to the ironpython folder.) I modified the file in  the ironpython folder... modifying it in the default directory in C:\Python25 fixed it

Thank You :-)

Andrew,

I'm happy to see that someone is trying to use pyreadline (I'm the maintainer of pyreadline) on ironpython. I have not tried it myself for a long time so I have no idea how much bitrot has crept into it. If you have any patches to make it work out of the box I would be happy to include it.

Please file any patches via the bugtracker:
