How to make a mode dependent operation ?

How to make a mode dependent operation ?

[Fren Zeee]

Here is a simple newbie problem :

In c-mode, I want to insert a skeleton of function as


 () {



}


and In lisp-mode, I want

( defun ()
""


)


and similarly in scheme, java, python, haskell, pascal ...


What is the quick but maybe not the dirty way to do it ?


What is the PRO way to do it ? I have heard a little about the hooking
hooks :)


What is a hook and what is proper place of use ? Is it appropriate for
this kind of private customization ?

See either (info "(autotype) Top") in bare Emacs, or yasnippet here:

Hi,

To create a mode-specific operation, or a function that has different 
behaviors based on the major-mode of a given buffer, you can use 
'mode-local'.

Mode-local is a part of Emacs 23.2, and you can use 
define-overloadable-function to create the default behavior.  Then for 
each mode, use define-mode-local-override to create an implementation 
for that mode.

If you are specifically looking into template insertion, there is 
SRecode which is just another template system like skeleton, tempo, etc. 
  It is targeted at mode independent code generation, and has some 
templates for C, lisp, and Java already for basic function creation. 
Tools like autocomplete or yasnippet has a better UI if you want to 
insert random small bits of text.

To turn on SRecode, use global-srecode-minor-mode.
