c-set-style question

c-set-style question

[jronald]

Which variable does this function change? Is there?

There is another a variable called c-default-style, which isn't changed by
the function.What is the effect of it.

I would suspect a lot of buffer local variables that control
indentation.

C-h v c-default-style RET

will tell you.

If you just want to customize the indentation of C code you
should ask a bit more specific questions (and btw. CC mode
comes with a pretty good manual that describes it's
indentation very detailed).

It's in the docs type C-h v c-default-style

c-default-style is an alist determining the style to be used by all
C-like languages.  It is used before mode-specific hooks are run.  Then
once in CC mode c-set-style can be used to change the mode on the fly.

So, c-default-style is most useful for writing you .emacs files,
c-set-style is most useful to change the style during editing.  You
could use c-set-style to change the style in a hook if you liked though.

By consulting c-default-style in emacs's doc,
it says:

c-default-style's value is
((java-mode . "java")
 (other . "gnu"))

but I'm editing a .cpp file.

c-default-style is a CC mode variable.  CC mode deals with all
langauges that are similar to C, such as Java, C++, C, and lots of
other obscure langs.  When you see "c-mode" in a buffer it means that
you're using a C mode that is internally part of CC-mode.

As a result this variable can have values for every one of these
programming languages.  For example, you can do:-

(setq c-default-style "k&r") ;; Use kernigham & ritchie style for
everything
or specifying different styles for each mode that CC-mode controls..
(setq c-default-style '((java-mode . "java") (c-mode . "gnu") (other .
"whitesmith")))

I think the name is rather confusing, it probably should be changed.

Helpful, thans.
