[Pydev-code] Getting started with PyDev scripting

[Joel H. <yo...@if...>]

Hi!

I'm trying learn Jython scripting for PyDev in order to implement feature=
=20
request #1450378 (mine :-).

http://sourceforge.net/tracker/index.php?func=3Ddetail&aid=3D1450378&grou=
p_id=3D85796&atid=3D577332

Fabio gave me a neat starter guide and a code example from the cvs java s=
ource=20
(see feature request page above), but I've got a few questions before I c=
an=20
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 method=
s of=20
an object in Jython scripts for PyDev? I'm a CPython programmer and I'm u=
sed to=20
having dir(), help() and the inspect module for peeking into strange obje=
cts,=20
but none of them seems to do me any good here. Afaik the help() function =
is not=20
implemented in Jython 2.1, but why can't I import the inspect module? Als=
o, why=20
does dir(editor) return an empty list? (example at the end) What's the=20
recommended way of finding out information on object methods and data mem=
bers=20
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 quest=
ion,=20
but as I'm not a java black belt I feel a little disoriented. PyEdit obje=
cts=20
apparently have a .getSite() method (line 32 in pyedit_example2.py in the=
=20
starter guide), but the org.python.pydev.editor.PyEdit class does not def=
ine it.

http://cvs.sourceforge.net/viewcvs.py/pydev/org.python.pydev/src/org/pyth=
on/pydev/editor/PyEdit.java?rev=3D1.91&view=3Dmarkup

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=20
using an editor object, but the code example I got from Fabio apparently =
does=20
not. Instead it uses a PySelection object that it gets as its first argum=
ent.=20
The PyEdit argument is apparently not used.


This Jython scripting thing seems really powerful and I hope I'll be able=
 to=20
produce some nifty things with it once I'm up to speed.

Cheers!

Example:
$PYEDIT_SCRIPTS/pyedit_test.py:
---------------------------------------------------------------------
assert cmd is not None
assert editor is not None
dir(editor)
import inspect
---------------------------------------------------------------------

Console output on save:
---------------------------------------------------------------------
--->  reloading /.../pyedit_test.py

Traceback (innermost last):

   File "/<PATH_SNIPPED>/pyedit_test.py", line 4, in ?
