Hello,
I work on a project that uses Python as the basis for a very domain
specific development environment.
For documentation and training purposes I'd like to use IDLE as the
initial development tool. In other words, my "getting started"
documentation and class exercises for example, would be produced in
terms of IDLE.
Thus far, this works quite well, IDLE strikes the right balance between
simplicity, accessibility and capability.
I'm glad to hear - it means IDLE meets its goals :)
One issue is that our development environment has a number of domain
specific text files used in the process of developing applications.
Naturally, IDLE is able to edit these files with no problem. I would,
however, now like to add syntax colorization and possibly indentation
support for these text files.
Has any one done this? Any thoughts on the proper approach or other
hints would be greatly appreciated. If there is some reason that this
would be a Bad Idea, let me know that as well...
AFAIK and as far as 10 minutes of Google-ing can tell, this hasn't been
done. But I don't see any reason why this would be a Bad Idea.
As for thoughts on the proper approach: This could be an IDLE "extension".
See idlelib/extend.txt for an introduction to extensions, and check out some
of the built-in extensions, like ParenMatch and CodeContext.
For some technical details, check out EditorWindow.py:
self.per = per = self.Percolator(text)
if self.ispythonsource(filename):
self.color = color = self.ColorDelegator()
per.insertfilter(color)
else:
self.color = None
What your extension should do is call per.insertfilter(custom_colorizer),
where custom_colorizer would be your colorizer object. Your colorizer class
should inherit Delegator - see Delegator.py. Also see the implementation of
ColorDelegator in ColorDelegator.py, for a starting point.
Feel free to bug me with questions, I'd be glad to help :)
