python mode

python mode

[Gary Wessle]

Hi

I opened a file.py but emacs 21.4.1 on debian testing didn't switch
the mode to the python mode. what do I need to do to fix this. 


http://www.emacswiki.org/cgi-bin/wiki/PythonMode
Gnu emacs post 21 has its own python mode (python.el). This is enabled
by default for .py files so you don\u2019t have to add anything to
your .emacs to use it.


thanks

Check auto-mode-alist. If it does not contain an entry for Python  
files or the wrong mode correct this with something like:

	(add-to-list 'auto-mode-alist '("\\.py\\'"	 . python-mode))

I placed the line you suggested in my .emacs and load-file .emacs
then opened my.py file but I am getting
file mode specification error: (void function  python-mode)

So you first need to load or require your Elisp file with the  
definition of python-mode in it.

I thought that python.el file is included in the installed emacs as it
has been indicated in the wiki, do I need to get it and place it in
where the other .el files are?

In my distributions of GNU Emacsen the standard python.el file is  
located in lisp/progmodes. The file is not (pre-)loaded by default,  
it must be loaded when needed as for example htmlize-view or AUCTeX  
or preview-latex etc. If an Elisp file has a provide statement, you  
can require it, otherwise you need to load if. You can you use the  
autoload function to load an Elisp automatically when it's needed,  
maybe this way:

	(autoload 'python-mode "python" "Handle Python files appropriately." t)

But actually such a finesse is not needed since GNU Emacs loads the  
code into memory late, when actually needed for to do specific work.  
So a simple load or require statement in .emacs is good enough.

in my debian testing system
# locate python.el
/usr/share/emacs/site-lisp/semantic/wisent/wisent-python.el

the file python.el does not exist.

So try this! If it's not sufficient get GNU Emacs source and compile,  
if you can't find a useful deb package! Check load-path whether it  
contains /usr/share/emacs/site-lisp/semantic/wisent, otherwise you  
would need add this component. ( (add-to-list 'load-path "...") )

BTW, you've located the wisent-python.el file in the site-lisp tree.  
So this is definitely not a GNU Emacs file, but something specific to  
your system. The GNU Emacs one would be in /usr/local/share/emacs/ 
<version number>/lisp/progmodes ...

the one that comes close is  "/usr/share/emacs/21.4/lisp/progmodes"
in it there is no file about python-mode.elc or any thing for python
for that matter. with debian, I'd rather not start compiling my own
emacs from source because my in-ability to understand how the rest of
the system interact with emacs and visa-versa and how to satisfy that
not to have any future problems. I got python-mode-1.0.tar.gz and in
it there is 
doctest-mode.el  
pycomplete.el	
pycomplete.py  
python-mode.el
semantic.cache

should I just move python-mode.el to ../progmodes/ and compile? as it
said in the installation instruction in python-mode.el?
if so, could you tell me how to compile the file so that it is .elc
like all the other files in progmodes?

thank you

No, you better put them all into a place like the site-lisp tree so  
that they survive a GNU Emacs update! And these files do not seem to  
be a regular part of an Emacs distribution, so they're better stored  
outside.

In dired-mode you can mark the .el files and command B, which will  
byte-compile them.

Emacs-21.4 is in the family "Emacs-21", so it's not *post*-Emacs-21.
There is no released Emacs version with built-in python mode.  You can use
Emacs-CVS or install python.el manually.

also, Debian 'unstable' has emacs-snapshot, which is the latest CVS
emacs and is updated approximately weekly. I've been using it
exclusively as my emacs for the past month and it works very nicely. 

My base system is Debian testing (etch), but I have unstable apt
repositories in my apt sources file (and a apt setting specifying that
testing is my preferred distribution). This prevents apt-get from
trying to update all of the packages in unstable - once you choose a
package from unstable, it will only install whatever prerequisites
that package needs from unstable and then only upgrade those when
necessary - outcome is you can use package from both testing and
unstable (but don't get too carried away!).

Well, here is my sources.list file. It won't be much good to you
though as I use a private mirror, but should give you the picture -

deb http://www.mwolson.org/debian/ ./
deb ftp://mirror.internode.on.net/debian testing main contrib non-free
deb ftp://mirror.internode.on.net/debian unstable main contrib non-free

and my apt.conf is

APT {
	Default-Release "testing";
	Get {
		Fix-Broken "true";
		Show-Upgraded "true";
	};
};
