New code should be formatted according to .clang-format file before committing it in a pull request. ( https://clang.llvm.org/docs/ClangFormat.html )
It can be installed with apt install clang-format or zypper in clang-tools
Only the modified code should be reformatted using clang-format, otherwise the code diff files get impossible to review. Use git-clang-format to do this (see below).
Checking XS files
To also correct the formatting of XS files, configure clang-format to use the clang-format-xs wrapper like so
git config clangformat.extensions c,h,xs
git config clangformat.binary $PWD/utils/clang-format-xs/clang-format-xs
Manual check after git add
Use:
git clang-format
Auto-check format on commit
To ensure the clang-format formatting before committing, I found this tool:
https://github.com/ailin-nemui/clang-format-hooks
To use it, first clone the repo ( git clone https://github.com/ailin-nemui/clang-format-hooks.git )
Then, run the installer script inside your Irssi clone:
cd /path/to/src/irssi
../clang-format-hooks/git-pre-commit-format install
The next time you try to commit, the formatting will be checked!
