It is a java thing -- comes from java.lang... Actually you should import it
into your scope: from java.lang import StringBuffer.
You can check its javadocs at:
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/StringBuffer.html


Oh, and is there something similar for retrieving the contents of

Actually, the current version seems nice to me... It actually uses the
ParsingUtils to get the parents, so, it should be ok.  Also, in the tuple
you have in the return, 'tuple.o2' will give you the parenthesis end
-- You can check that function at:
http://cvs.sourceforge.net/viewcvs.py/pydev/org.python.pydev.core/src/org/p=
ython/pydev/core/docutils/PySelection.java?view=3Dmarkup

Sure... Actually, I have in my 'todo-list' doing a developers manual, on ho=
w
to get the code, so, I guess I'll put this there too.

One impression is that there seem to be very little documentation. Maybe

Well, actually most code has javadocs, so, probably doing at least a javado=
c
from pydev code and making it available would be a good addition to that. A=
s
for the cvs stuff, that developers manual would surely help -- It should be
pretty easy getting the pydev code in Eclipse.

If you want to elaborate on them, you can put it in this list (and put it
later in the tracker), now, if you're sure of what you want, just toss it i=
n
the tracker .
