Contributor Guidelines

Getting started

To set up your local environment, from the top level of the checkout run

./contrib/setup

This will create pre-commit hooks to fixup many code style issues before your code is submitted.

On some Linux distributions this will install all build dependencies needed to compile fwupd as well.

Coding Style

The coding style to respect in this project is very similar to most GLib projects. In particular, the following rules are largely adapted from the PackageKit Coding Style.

  • 8-space tabs for indentation

  • Prefer lines of less than <= 100 columns

  • No spaces between function name and braces (both calls and macro declarations)

  • If function signature/call fits in a single line, do not break it into multiple lines

  • Prefer descriptive names over abbreviations (unless well-known) and shortening of names. e.g device not dev

  • Single statements inside if/else should not be enclosed by '{}'

  • Use comments to explain why something is being done, but also avoid over-documenting the obvious. Here is an example of useless comment:

    // Fetch the document fetch_the_document();

  • Comments should not start with a capital letter or end with a full stop and should be C-style, not C++-style, e.g. /* this */ not // this

  • Each object should go in a separate .c file and be named according to the class

  • Use g_autoptr() and g_autofree whenever possible, and avoid goto out error handling

  • Failing methods should return FALSE with a suitable GError set

  • Trailing whitespace is forbidden

  • Pointers should be checked for NULL explicitly, e.g. foo != NULL not !foo

./contrib/reformat-code.py can be used in order to get automated formatting. Calling the script without arguments formats the current patch while passing commits will do formatting on everything changed since that commit.
