means each and every commit in a pull request should make sense both on its
own and in general context. That is, a second commit should not resolve an
issue that is introduced in an earlier commit. In particular, you will be
asked to amend any commit that introduces syntax errors or similar problems
even if they are fixed in a later commit.</p><p>The commit messages should follow the <aclass="link"href="https://chris.beams.io/posts/git-commit/#seven-rule"target="_top">seven
rules</a>, except for
“Capitalize the subject line”. We also ask you to include the affected code
component or module in the first line. A commit message ideally, but not
necessarily, follow the given template from home-manager’s own documentation</p><pre><codeclass="programlisting"> {component}: {description}
</code></pre><p>where <codeclass="literal">{component}</code> refers to the code component (or module) your change
affects, <codeclass="literal">{description}</code> is a very brief description of your change, and
<codeclass="literal">{long description}</code> is an optional clarifying description. As a rare
exception, if there is no clear component, or your change affects many
components, then the <codeclass="literal">{component}</code> part is optional. See <aclass="link"href="index.xhtml#sec-guidelines-ex-commit-message"title="Example Commit">example commit

the commit followed by the description:</p><pre><codeclass="programlisting">languages/ruby: init module
Adds a language module for Ruby, adds appropriate formatters and Treesitter grammers
</code></pre><p>Long description can be ommitted if the change is too simple to warrant it. A
minor fix in spelling or a formatting change does not warrant long description,
however, a module addition or removal does as you would like to provide the
relevant context, i.e. the reasoning behind it, for your commit.</p><p>Finally, when adding a new module, say <codeclass="literal">modules/foo.nix</code>, we use the fixed
commit format <codeclass="literal">foo: add module</code>. You can, of course, still include a long
description if you wish.</p><p>In case of nested modules, i.e <codeclass="literal">modules/languages/java.nix</code> you are recommended
to contain the parent as well - for example <codeclass="literal">languages/java: some major change</code>.</p>
