Hi,
I would like to know if geany supports [1] plugin creation using python [2] dynamic loading of plugins without re-compiling it from sources.

Not yet, unfortunaly.
[2] dynamic loading of plugins without re-compiling it from sources.
What do you understand with this?
Two possibilities: 1. I create a shared object and put it under plugins directory and it gets loaded the next geany is opened. 2. Still better, I write the plugins using scriting language such as python in a way geany expects and place it under plugins directory and the next time geany is opened, it loads the plugin.
The advantage of supporting a scripting language is the ease of development/contribution. Plugins being non-core components can afford the small overhead of slower execution I suppose.
Anyway, if thought useful, would like to request this as a feature for future support.
regards Shiv

Already possible, see HACKING file in the Geany sources.

It is possible to write Lua scripts for Geany, using the GeanyLua plugin from: http://yetanothergeek.justfree.com/geanylua
Python support has been discussed here before, but as far as I know, nobody is currently working on it.

I just changed the TODO wishlist item for Python scripting to 'Python plugin interface' - IMO there's no need for a competing Python variant of your great Lua plugin. It would be more useful to have Python bindings for the plugin API, so plugins could be written in Python instead of C. This would be harder to write than a Lua user 'script' but would also be more flexible, if it used pygtk. Of course this is only a wishlist item, don't anyone expect it to get done ;-)

hehe, maybe this could be a start...
It generates 100k+ lines of C code and about 5300 lines of python, along with a shared lib - but I have no clue what to do with it!

Thanks, this looks great, but I haven't been able to test it.
Unfortunately I can't seem to get python-config installed (on Fedora 5, Python 2.4). Fedora seems to have no package for it until v7 or later, when it's included with Python. So I tried downloading it from: http://www.red-dove.com/python_config.html
But I'm not sure this is what I need. I installed it with: python setup.py install
But that just installed a config.py module, which doesn't seem to be what I want (it ignores --libs, etc).
Anyway, I'll try to test the script on a more recent distro soon.
Regards, Nick

For my Fedora 8-System its python:
$ rpm -qf `which python-config` python-2.5.1-15.fc8
But i don't know how this is on Fedora 5...

That seems a logical place for it, but alas on Fedora 5 no cigar. I have a laptop with Fedora 8 on it, I'll try that next week.

As far as this script is concerned, you could probably do without it it, provided you at least have the Python headers installed.
Just remove the line that says: python-config --libs > /dev/null || exit
And then change: $(python-config --includes)
To something like this: -I/usr/include/python2.4

OK, thanks, this works. But (I assume) the generated bindings won't work, as swig probably expects the geany functions and global variables to be in a shared library. Also there would be problems with looking up plugin symbols from Geany, this would need to be coded specially. Still it's interesting anyway ;-)

I think
-I/usr/lib/python$(shell python -c "import sys;print sys.version[:3]")
will be better.
My dead project tw-light call python code. It uses swig to generate wrapper to make C/C++ variables and functions available in python code. I think It's source can be used to make python plugin as you described.

Maybe have a look at the now-standard Python ctypes module.

Could be less work than you're expecting.

Thanks for this info. I think whichever automated generation approach is best, there will still be work to do in making it work with Geany, and I expect it would require changes to the plugin system. So I won't work on this for now.
