code folding, a unique problem to python?

[John Salerno]

Specifically, I'm using UltraEdit and perhaps there's no way perfect way
to implement code folding with it, given how it uses its syntax
highlighting file to do so (i.e., you have to specify an "Opening" and
"Closing" character in which to enfold code, such as braces).

But my question is more general: is it possible to implement code
folding with Python given that it has no real block delimiters? Or is
this still a matter of which particular editor/IDE you use? For my part
I've tried (as was suggested elsewhere) to use 'def' as an opening and
closing keyword, but this of course will enfold everything between two
defs, even if you have more code between your function definitons (such
as a new class definition).

So maybe I'm stuck in UE, but I'm curious if there is some general way
to do this, or is Python just too simple and concise for its own good?

since the Python syntax *has* real block delimiters (look up INDENT and
DEDENT in the language reference), it's an editor issue.

There are many editors that do this. For Python, folding is based on
IDENT and DEDENT tokens. You can look for their definition in the Python
Language Reference.

For example, SPE can do this. See this screenshot:

Yes, it is an editor thing. In Vim, it's as simple as

:set foldmethod=indent

and presto! I'm sure other quality editors provide similar
options.

Most editors are "just too simple and concise for [their] own
good".

Eric3, the Qt-based and in python written IDE can do that. So I'd say
it's an UE-problem - nad it has to be: to perform folding, one has to
find out what constitutes a block. Obviously this CAN be done with
python-code - do it CAN be done in editor code.

Interesting. This might help me then, assuming UE can use characters
other than strings to delimit blocks.

Thanks!

::lowers head in embarassment:: I wanted to try out Eric3, but I
couldn't figure out how to install it! Is there a binary file? All I
found was a zipped file with a bunch of stuff I didn't recognize in it.
There was even a file called eric3.py which I thought might be it, but
running it did nothing.

You'll need PyQt to run that one. And QScintilla too.

SciTE can fold Python.

SciTE can fold Python.

If only there were a way for users to bind key-sequences...

also the free ActivePython's Pythonwin IDE

All other good editors can too. So general answer to this question is
"yes". Because Python *has* real block delimiters...

I can't speak for UltraEdit, but the Zeus will quite
happily fold Python code:
