Automatically enable python mode

Automatically enable python mode

[Olive]

I am using arch GNU/Linux. If a file contains:

#! /usr/bin/python

as the first line, the python mode is automatically enabled. However,
due to the fact that python 2 and python 3 coexists, in order that
the correct python version is reliably involved, the first line must be

#! /usr/bin/python2
or
#! /usr/bin/python3

How can I tell emacs that it have to automatically enable python mode
when one of the two line is the first line?

Olive,

The variable `interpreter-mode-alist' is what you want.

This worked for me to get Python2 recognized.

	(setq interpreter-mode-alist (add-to-list 'interpreter-mode-alist (cons "python2" 'python-mode)))

This can be found in the emacs *info* documentation at `Choosing Modes'.

I hope this helps.

,Doug
