C - marking code between braces.

C - marking code between braces.

[Pawel]

Hallo group members.

Could You tell me whether is there command in emacs that is able to mark code between braces, but not braces themselves?

Regards
Pawel

Yes: set-mark-command at begin and set-mark-command at end; or set- 
mark-command at end and set-mark-command at begin.

C-x (					; kmacro-start-macro (Emacs 22)/
					; start-kbd-macro

C-M-u					; backward-up-list
C-@					; set-mark-command
C-M-f					; forward-sexp
C-b					; backward-char
C-x C-x					; exchange-point-and-mark
C-f					; forward-char

C-x )					; kmacro-end-macro (Emacs 22)/
					; end-kdb-macro

Now `C-x e' magically marks the text between the innermost parentheses
(or brackets or braces).

Kevin, 
it does the job.
Thank You.

C-M-u
C-M-SPC
C-f
C-x C-x
C-b

or for only *one* level of braces

C-M-u
C-f
C-s }
C-b 

but this sets (marks) only the proper region and does not activate
(highlight) it.

Another idea for one level could be

C-M-r [^{}]+
C-M-s

but to my astonishment C-M-r does not skip to the char behind {!

I think the key is here:

,----[ C-h f search-backward-regexp RET ]
| [...]
| Search backward from point for match for regular expression REGEXP.
| Set point to the beginning of the match, and return point.
| The match found is the one starting last in the buffer
| and yet ending before the origin of the search.
| [...]

C-M-r and C-M-s asymmetric [was: C - marking code between braces]

Sorry Johan, I don't get it, the behaviour might be consistent with
the description above but the fact is that + should be greedy.  Please
search with C-M-s for "o.*o" in the following line

hans otto otto otto hans

When you C-M-r wouldn't you expect to find the same matches?  This is
clearly not the case and I can't imagine why.
