Hi!
I'm trying learn Jython scripting for PyDev in order to implement feature
request #1450378 (mine :-).
http://sourceforge.net/tracker/index.php?func=detail&aid=1450378&group_id=85796&atid=577332
Fabio gave me a neat starter guide and a code example from the cvs java source
(see feature request page above), but I've got a few questions before I can
start getting productive.
1) How do I find out PyEdit object methods and data members?
What is the best way of finding out the available members and data methods of
an object in Jython scripts for PyDev? I'm a CPython programmer and I'm used to
having dir(), help() and the inspect module for peeking into strange objects,
but none of them seems to do me any good here. Afaik the help() function is not
implemented in Jython 2.1, but why can't I import the inspect module? Also, why
does dir(editor) return an empty list? (example at the end) What's the
recommended way of finding out information on object methods and data members
in Jython?
2) Where do I find the source for the relevant superclasses?
I tried browsing the PyDev source cvs for the answer to my previous question,
but as I'm not a java black belt I feel a little disoriented. PyEdit objects
apparently have a .getSite() method (line 32 in pyedit_example2.py in the
starter guide), but the org.python.pydev.editor.PyEdit class does not define it.
http://cvs.sourceforge.net/viewcvs.py/pydev/org.python.pydev/src/org/python/pydev/editor/PyEdit.java?rev=1.91&view=markup
PyEdit implements IPyEdit, but how do I get to the source for it (or some docs)?
3) How do I affect code in the editor with only a PyEdit object?
From the starter guide I understand that Pydev scripts communicate with PyDev
using an editor object, but the code example I got from Fabio apparently does
not. Instead it uses a PySelection object that it gets as its first argument.
The PyEdit argument is apparently not used.
This Jython scripting thing seems really powerful and I hope I'll be able to
produce some nifty things with it once I'm up to speed.
Cheers!
