match if-then-else, brackets etc.

match if-then-else, brackets etc.

[Detlef Jockheck]

Hi,

whenever I analyze a programm in c, perl or pythen I have some problems to 
find the matching statement. Thant means I'm looking for the end of an 
if-declaration. Or where does this bracket belong to. Is there a plugin to 
hilight this dependencies in emacs?

ciao

This will highlight the matching parenthesis/curly bracket/whatever:

,----
| (setq show-paren-delay 0)
| (show-paren-mode t)
`----

And this will make control-right to move the cursor to the matching
parenthesis/curly bracket/whatever

,----
| (defun match-paren (arg)
|   "Go to the matching parenthesis"
|   (interactive "p")
|   (cond ((looking-at "\\s\(") (forward-list 1) (backward-char 1))
|         ((looking-at "\\s\)") (forward-char 1) (backward-list 1))
|         (t (condition-case nil (progn (re-search-forward "\\s\(") (backward-char 1)) (error nil)))
|         ))
| 
| (define-key global-map [(control right)] 'match-paren)
`----

For parentheses and brackets and curly braces:
M-x show-paren-mode RET
-- 
file-error; Data: (Opening input file no such file or directory ~/.signature)

Kai,

M-x show-paren-mode says  [no-match]. I've tried this in python-mode and in 
c-mode. Do I need to install an additional tool?

Oops!

Now I know why it doesn't work. It's because I'm using xemacs (not emacs). 
I thougt that this is approx. the same but I seems that it isn't.

How can I solve my problem with xemacs?

I suggest you take a look (with C-h k for example) at the key-bindings
C-M-f, C-M-b, and C-M-u.
