C++ Mode: Interpretation of Underscores In Words

C++ Mode: Interpretation of Underscores In Words

Hello:
 
Given a variable like "employee_name" is there a way to make emacs treat this as one word.  Would be nice when doing commands like "forward-word" which treats employee_name as two words.  
 
Thanks in advance.

Use forward-sexp which does just that in this case.

The word boundary is controlled by the syntax table. You can change the syntax of _ to be part of the word using modify-syntax.
Do C-h f modify-syntax RET to get help on the defun. This however may affect other features that depend on syntax table.

or while in cc-mode:

M-x modify-syntax-entry RET _ RET w RET

but, as Stefan wrote, there are C-M-f and similar.


PS: please stop posting in HTML.

HTML posts are less accessible then plain-text ones, HTML posts make
archives less useful to search with grep & co, they take more space
and bandwith, they are nearly-unreadable for many peoples who have no
HTML redering configuration, and take away (cpu-)time to peoples who
have it.  plain-text is enought for mail, anyone setups its MUA/NR to
display mails with the fonts/colors/font-size he wants, paragraph
separator can be an empty line.

Here are the two steps you need to do.  Both are required!

1 - Reconfigure your client to turn off HTML when posting to news
    groups and mailing lists.

2 - Add this to your .emacs:

(add-hook 'c-mode-common-hook
	  (function (lambda ()
		(modify-syntax-entry ?_ "w" c++-mode-syntax-table)
		(modify-syntax-entry ?_ "w" c-mode-syntax-table)
		(modify-syntax-entry ?_ "w" java-mode-syntax-table)
)))
