python-mode changes in 22.3?

python-mode changes in 22.3?

[Chris Withers]

Hi All,

I've been using an antique version of python-mode for many years and 
have just made the lead to 22.3, which ships with python mode.

However, there are a few changes that are causing me problems:

- the comment/uncomment menu items on the python menu have vanished. How 
do I get these back?

- hitting return after, say, "def myfunc():" used to leave me at the 
right tab level. It no longer does. I have to hit tab. How do I get it 
so that I don't have to hit tab anymore, which is how it used to behave?

If there's a better list to ask about python-mode, please let me know!

cheers,

Chris

Emacs22 ships with it's own python-mode ("python.el") which is
different from "python-mode.el" (which comes with python). Read all
about it here:

  http://www.emacswiki.org/emacs/PythonMode

Maybe you just want to continue using Python's python-mode...

There also was a lengthy thread about this some days ago:

HTH, 

Anselm

You can be defining your own menu, but maybe you just want to start
using the universal comment commands, e.g. comment-or-uncomment-region.

Again, you can use the general Emacs mechanism for this.
By default, the <return> key is bound to `newline'.  You might want to
change it to `newline-and-indent'.

(global-set-key "\C-m" 'newline-and-indent)

I should have known this was possible really ;-)

Where can I find out how to do this?

(or if you're feeling generous..)

What do I put in my .emacs file to add two entries to the python menu:
- comment selected region
- uncomment selected region

That said, if we're adding menu items, how could I add one that 
basically did "shift region right", but twice?

I don't use the menus, only keys, so I can't do it for you.

Check out the Emacs manual
- 22.17.1.2 Extended Menu Items

I think they are extended the same way as binding commands to keys.

First you need to write such a command. (Then bind the command to a
menu.)

(defun my-command-name ()
  (interactive)
  (call-interactively 'original-command-name)
  (call-interactively 'original-command-name))

You can find the original command name with C-h k <click on menu>.

Customising the menu for python-mode

Fat lot of good that did me ;-)

I tried monkey-see-monkey-do-ing from python.el and so far have this in 
my .emacs file:

;; menu items
(defvar chris-mode-map
   (let ((map (make-sparse-keymap)))
     (easy-menu-define python-menu map "Python Mode menu"
       `("Python"
	:help "Python-specific Features"
	"-"
	["Comment" python-shift-left :active mark-active
	 :help "Comment"]
	["Uncomment" python-shift-right :active mark-active
	 :help "Uncomment"]))
     map))

Which, while it doesn't error, also does nothing.

What am I doing wrong?

cheers,

Chris

Nothing wrong, just not enough.  You've defined a keymap, but you also
need to activate it.

You can do it like this:

(define-minor-mode chris-mode
  "my menu mode"
  nil nil chris-mode-map)

And then enable `chris-mode'.

Of course you can also modify python-mode-map (or whatever it is called)
instead of creating your own map, so python-mode will take care of
activating the map.

How do I do this? This sounds like what I'm after but my lisp foo is 
*very* weak...
