Formatting comment lines (C code)

Formatting comment lines (C code)

[luca.spinacci]

I would like to format my comment lines
replacing all spaces and tabs between
'//' and the comment text with only one space.
Ex.
//____Text.... => //_Text

where '_' is a space.

I use replace-regexp "[^ a-zA-Z0-9/\.]" " "
on a selection of my code but it
doesn't work very well because replaces
characters in the comment text
- for instance replaces )(!-, etc. -.

Any suggestion?

Thank you very much.
Luca

Hi,

you can use
M-x replace-regexp "\(//\s \)\s *" "\1"

Note:
1. it doesn't insert a space if it is missing like in "//comment".
2. it uses "\s " what means "any character whose syntax is whitespace". See:
C-h s. ...

Br,
P
