citus_indent wraps uncrustify, a popular C source code beautifier. When invoked, it immediately applies Citus C style on any git-tracked C files under the current working directory, though a --check flag is implemented to check style without modifying any files.
citus_indent requires uncrustify v0.68 or greater.
make install to install the script, the Citus style configuration file, and a man page. man citus_indent for more details.
Apply the citus-style git attribute to any files that need the Citus C style applied. After that, just ensure you're within the project's directory hierarchy and run citus_indent to format all files. Add style changes with git add -p.
citus_indent --check is useful for scripts: it will not modify any files and simply exits with a non-zero status if any files marked with citus-style are non-compliant.
