| How much begging, prodding, crying and worshipping would it take to get Python added to the list of supported scripting languages?
I don't know what interface you're using, but if its the ActiveX/Windows Scripting Host, then Python interfaces to it just fine with the win32all package...
Plllease? :) | | Top |

| | I tried that - the appropriate changes are in the code, however it didn't work. Some bizarre interface problem. Unless they have fixed up the Python script interface I can't do it. |

| Don't get me wrong - I would if I could - I had a demo bit of source that reproduces the fault that I sent to WillFa (see earlier posts).
If I can make that work, or if someone can tell me what I am doing wrong, I'll put it in. You are welcome to a copy. |

| Do you mean:
m_IActiveScript->AddNamedItem (L"world",
SCRIPTITEM_ISVISIBLE | SCRIPTITEM_ISSOURCE);
in reference to the demo, or did you send a different bit? Since you said it crashed even without the above, I was wondering if I missed something.
Can you provide details on what sort of crash? What error message; access violation, etc? I might be able to do some digging for you. | | Top |

| Yes, that is what I meant.
This is what I had last time:
// pScriptEngine = new CScriptEngine (this, "vbscript"); // this works
pScriptEngine = new CScriptEngine (this, "python"); // this doesn't
If you change the language to "vbscript" then it works and displays the message box. Otherwise you get the message about the ESP value. If you comment out the line that adds the "world" variable to the script engine it crashes anyway (scripttengine.cpp line 210).
The files are largely unchanged from the MUSHclient version, in the stdafx.h file is a define:
#define CMUSHclientDoc CScripttestDoc
This is so that the files think it is using a CMUSHclientDoc document.
If you can get this to work (changing compile options or something?) then I should be able to make MUSHclient work too.

| I don't know about this "declared with a different calling convention" bit - the exact same code works if you change the language to Vbscript, Jscript, or Perlscript.

| Hmm. Did a bit of hunting and found that most things dealing with Python and 'calling convention' involve the facts that Python and C++ do not automatically use the same method. While my brief search didn't uncover specifics, one possibility is that Python uses the Pascal convention and in that case the difference involves stack management. The method C++ uses is 'caller clears the stack', while the pascal method employs 'the program called clears the stack'. This is only a guess though, but it suggests that a key process is either being done by both ends or by neither end and this would definitely cause a crash.
Wish I knew if this was the case or how to actually fix it though.. I imagine that changing the calling method to properly support Python could break everything else, so there has to be some sort of better solution. :p | | Top |

| After making a subtle change to the way scripting was instantiated - after spending hours reading web pages - I now have Python active (nothing to do with calling conventions BTW). However after a script error in "immediate" mode it stops processing further scripts. I am investigating this.
Meanwhile, as a newbie to Python, perhaps a few examples of the sort of thing you would like to try would help me to test it. |

| Like, for instance, how do I cast types?
Here is a simple example. In the plugins I echo the description by getting plugininfo, which is a variant, and displaying it with Note, which takes a string. Like this:
/world.Note (world.GetPluginInfo (world.GetPluginID, 3))
This gives a type mismatch.

| Hmm - I withdraw that comment slightly - the error was when not running as a plugin, so it probably got an empty variant.
My experimenting seems to indicate that str(x) casts x to a string.
What about the format for constants? See this page:
http://www.gammon.com.au/scripts/function.php?action=errors
Can you suggest the syntax (for one line, I can work out the rest) for the constant list? This is auto-generated by the page anyway, I just need the format to do it.
