Commit message style guide for Git

The first line of a commit message serves as a summary.  When displayed
on the web, it's often styled as a heading, and in emails, it's
typically used as the subject.  As such, you should capitalize it and
omit any trailing punctuation.  Aim for about 50 characters, give or
take, otherwise it may be painfully truncated in some contexts.  Write
it, along with the rest of your message, in the imperative tense: "Fix
bug" and not "Fixed bug" or "Fixes bug".  Consistent wording makes it
easier to mentally process a list of commits.

Oftentimes a subject by itself is sufficient.  When it's not, add a
blank line (this is important) followed by one or more paragraphs hard
wrapped to 72 characters.  Git is strongly opinionated that the author
is responsible for line breaks; if you omit them, command line tooling
will show it as one extremely long unwrapped line.  Fortunately, most
text editors are capable of automating this.

And then some.

All hooks can be used from the command line as well.

Available Hooks

check-description-max-length

Check lines in the description are not more than 72 characters.

check-second-line-empty

Check the second line of the commit message is blank.

check-summary-conjunction

Check the summary does not contain conjugated sentences.

Searches for occurrences of ‘and’, ‘nor’, and ‘or’ and fails if found.

check-summary-imperative

Check the summary starts with a verb.

Searches a wordlist comprised of > 6000 verbs. The check fails if not found.

The wordlist is comprised of different lists but as terminology evolves, the list is incomplete. If you find anything missing, please amend verbs-wordlist.txt and issue a Pull Request.

check-summary-capitalized

Check the summary starts with a capital letter.

check-summary-max-length

Check the summary is not more than 54 characters.

Note

https://commit.style says Aim for about 50 characters, give or take. 54 gives a little more lee-way.

check-summary-punctuation

Checks the last character against string.punctuation and fails on match.
