Changing Emacs Forward-Word Behaviour
emacs, emacs23
Solution
Try:
(require 'misc)
Then use `M-x forward-to-word` and see if it does what you want. You can then rebind `M-f`, etc.
To make the `_` not a word separator (i.e. make it a word constituent) for C & C++ mode, you would do this:
(modify-syntax-entry ?_ "w" c-mode-syntax-table)
(modify-syntax-entry ?_ "w" c++-mode-syntax-table)
For more information on syntax tables, read this wiki page. Syntax tables are generally named like `tex-mode-syntax-table` and `cperl-mode-syntax-table`.
Problem
As the title says, how does one change the behaviour of emacs forward-word function? For example, suppose [] is the cursor. Then: ``` my $abs_target_path[]= abs_path($target); <M-f> my $abs_target_path = abs[_]path($target); ``` I know I could just use M-f M-b but as far as I'm concerned, that shouldn't be necessary and I'd like to change it. In particular, I want two things: - When I press M-f, I want to go to the first character of the next word regardless of whether the point is within a word, within a group of spaces or somewhere else. - Customize word-characters on a mode-by-mode basis. After all, moving around in CPerl mode is different than, say, TeX mode. So, in the above example, item 1 would have the cursor would move to the 'a' (and the point to it's left) after hitting M-f. Item 2 would allow me to define underscores and sigils as word characters.
