indent cpp file with emacs~

black · 09-08-2004, 12:13 AM

hi all~

i found emacs indentation went strange way when editing cpp file with it, below is what it did:

Code:

int Foo()
{
  int a;
  int b
    int c;
  int d;
}

as you can see first line within {} emacs indent two spaces and so did the second line, but if I omit the semicolon after b the third line will go four spaces instead, why ???
and, how can i make emacs indent 4 spaces not 2 here ?

thanx~

It's probably confused and thinks it's not delimited. Plus, why would you do that anyway

? If you think about it, if you do

Code:

if()
  blah

it will be tabbed so I guess it's for the best

it didnt help, i add it to the top of .emacs file but nothing changed, my .emacs file is something like this:

Code:

(setq indent-tabs-mode 2)
(custom-set-variables
  ;; custom-set-variables was added by Custom -- don't edit or cut/paste it!
  ;; Your init file should contain only one such instance.
 '(case-fold-search t)

...

any suggestions ?

hi there,

i would like to introduce you to tab-stop

Code:

(setq tab-stop-list '(3 8 16))

or whatever you want.

After that a visit to www.emacswiki.org will help a lot. It is a quite complete wiki

thanx for supply that site, i'll check it out soon. and is your code the same thing as command "edit-tab-stops" ? i fixed it but nothing works.

slackie1000 · 09-10-2004, 12:43 AM

hi there,

to use the tab stop list you need to switch indent tab modes also in your .emacs file:
(setq-default indent-tabs-mode 1)
i think you can find all these informations at emacswiki.
hope it helps.
