Please help: How to reformat existing c++ files using emacs

Please help: How to reformat existing c++ files using emacs

[Xiaopeng Xiong]

I have a bunch of files that look ugly (e.g., inappropriate indents). I just 
can not
type TAB at each line.

If there is any command for formatting all files under a directory, that
would be best. But currently, formatting a single file is enough for me. If 
you know any command to do so, please help!


Thanks a lot!

C-PgUp C-<SPC> C-PgDn M-x indent region or similar...

,----[ C-h f indent-region RET ]
| indent-region is an interactive compiled Lisp function in `indent'.
| It is bound to C-M-\.
| (indent-region START END &optional COLUMN)
| 
| Indent each nonblank line in the region.
| A numeric prefix argument specifies a column: indent each line to that column.
| 
| With no prefix argument, the command chooses one of these methods and
| indents all the lines with it:
| 
|   1) If `fill-prefix' is non-nil, insert `fill-prefix' at the
|      beginning of each line in the region that does not already begin
|      with it.
|   2) If `indent-region-function' is non-nil, call that function
|      to indent the region.
|   3) Indent each line as specified by the variable `indent-line-function'.
| 
| Called from a program, START and END specify the region to indent.
| If the third argument COLUMN is an integer, it specifies the
| column to indent to; if it is nil, use one of the three methods above.

Alternatively use a seperate tool such as gnu indent...

http://www.gnu.org/software/indent/indent.html

I find this a much better way to go for indenting
multiple files... also indent will do formating that
emacs will not! such as moving the position of
braces.

Although emacs is the One True Editor.. sometimes
it is better to use other tools.
