Libvirt contributor guidelines
|
|
==============================
|
|
|
|
|
|
Code indentation
|
|
================
|
|
Libvirt's C source code generally adheres to some basic code-formatting
|
|
conventions. The existing code base is not totally consistent on this
|
|
front, but we do prefer that contributed code be formatted similarly.
|
|
In short, use spaces-not-TABs for indentation, use 4 spaces for each
|
|
indentation level, and other than that, follow the K&R style.
|
|
|
|
If you use Emacs, add the following to one of one of your start-up files
|
|
(e.g., ~/.emacs), to help ensure that you get indentation right:
|
|
|
|
;;; When editing C sources in libvirt, use this style.
|
|
(defun libvirt-c-mode ()
|
|
"C mode with adjusted defaults for use with libvirt."
|
|
(interactive)
|
|
(c-set-style "K&R")
|
|
(setq indent-tabs-mode nil) ; indent using spaces, not TABs
|
|
(setq c-indent-level 4)
|
|
(setq c-basic-offset 4))
|
|
(add-hook 'c-mode-hook
|
|
'(lambda () (if (string-match "/libvirt" (buffer-file-name))
|
|
(libvirt-c-mode))))
|
|
|
|
Code formatting (especially for new code)
|
|
=========================================
|
|
With new code, we can be even more strict.
|
|
Please apply the following function (using GNU indent) to any new code.
|
|
Note that this also gives you an idea of the type of spacing we prefer
|
|
around operators and keywords:
|
|
|
|
indent-libvirt()
|
|
{
|
|
indent -bad -bap -bbb -bli4 -br -ce -brs -cs -i4 -l75 -lc75 \
|
|
-sbi4 -psl -saf -sai -saw -sbi4 -ss -sc -cdw -cli4 -npcs -nbc \
|
|
--no-tabs "$@"
|
|
}
|
|
|
|
Note that sometimes you'll have to postprocess that output further, by
|
|
piping it through "expand -i", since some leading TABs can get through.
|
|
Usually they're in macro definitions or strings, and should be converted
|
|
anyhow.
