emacs alphabetize methods

[John Hunter]

Using emacs python-mode with a class

class C:
def method1(self):
pass

def anothermethod(self):
pass

def method2(self):
pass

is there any way to select all the methods and have emacs order them
alphabetically? If not, is there a good too to do so?

Thanks,
John Hunter

Not that I am aware of - but this wouldn't be an impossible job to tackle
yourself and provide the results for benefit of the rest of us who uses
Emacs

My suggestion for how to do this (off the top of my head ) is to write a
support (Python) program to call from your emacs using Pymacs
(http://pymacs.progiciels-bpi.ca/manual/The--Pymacs--buffer.html).

Then you could probably locate the points where your methods start and
finish using services available from the Python Language Services section in
the Python Library Reference (Chapter 18), re-arrange the source code and
then re-insert it back into your Python buffer.

Probably not a very big job at all - if you don't do it then I might well do
it myself one day (but not in the foreseeable future due to other work loads
).

Regards,
Peter

Sort of, but there are problems. Emacs does have a sort-paragraphs
function. Python-mode has a py-mark-block command. If you place the
cursor at the start of the "class" line and hit C-c C-k you'll mark the
class. Hit C-n C-x C-x to highlight the block except for the class line
itself then M-x sort-paragraphs RET.

This has a gotcha. The notion of paragraph separator is basically a blank
line. To make this more effective you'd have to modify the
paragraph-separate variable. If you come up with a reasonable value for
Python code, send it along to (e-mail address removed) and we'll update
python-mode.el.

(http://pymacs.progiciels-bpi.ca/manual/The--Pymacs--buffer.html).

You can just call the program directly and use stdin/stdout:

(defun my-alphabize-region (beg end)
"Sort methods in region alphabetically."
(interactive "r")
;; run command with region as input, and replace it with the output
(shell-command-on-region
beg end
"myCommand" ;<<< Your command here
t t "*errors*"))


(You could do this entirely inside emacs of course.)
