When contributing with code, you agree to put your changes and new
|
|
code under the same license nghttp2 is already using unless stated and

agreed otherwise.

When changing existing source code, you do not alter the copyright of

the original file(s). The copyright will still be owned by the

changes as far as possible, to give credit but also to keep a trace

Coding style
|
|
------------
|
|
|
|
We use clang-format to format source code consistently. The
|
|
clang-format configuration file .clang-format is located at the root
|
|
directory. Since clang-format produces slightly different results
|
|
between versions, we currently use clang-format which comes with
|
|
clang-3.5.
|
|
|
|
To detect any violation to the coding style, we recommend to setup git
|
|
pre-commit hook to check coding style of the changes you introduced.
|
|
The pre-commit file is located at the root directory. Copy it under
|
|
.git/hooks and make sure that it is executable. The pre-commit script
|
|
uses clang-format-diff.py to detect any style errors. If it is not in
|
|
your PATH or it exists under different name (e.g.,
|
|
clang-format-diff-3.5 in debian), either add it to PATH variable or
|
|
add git option ``clangformatdiff.binary`` to point to the script.
|
|
|
|
For emacs users, integrating clang-format to emacs is very easy.
|
|
clang-format.el should come with clang distribution. If it is not
|
|
found, download it from `here
|
|
<https://llvm.org/svn/llvm-project/cfe/trunk/tools/clang-format/clang-format.el>`_.
|
|
And add these lines to your .emacs file:
|
|
|
|
.. code-block:: lisp
|
|
|
|
;; From
|
|
;; https://code.google.com/p/chromium/wiki/Emacs#Use_Google's_C++_style!
|
|
(load "/<path/to>/clang-format.el")
|
|
(add-hook 'c-mode-common-hook
|
|
(function (lambda () (local-set-key (kbd "TAB")
|
|
'clang-format-region))))
|
