Inspects the git log of the current branch for commit
|

messages looking like change entries. If any are found, add them to the

changelog.

C<git-gather> will inspect the git log from the most recent of those
|
|
three points:
|
|
|
|
=over
|
|
|
|
=item The last change in the NEXT release having a C<commit> property.
|
|
|
|
=item The last tagged version.
|
|
|
|
=item The beginning of time.

|

=back
|
|
|
|
=head2 Change-like git message
|
|
|
|
Git messages are compared to the regular expression
|
|
configured at `project.commit_regex`. If none is found, it
|
|
defaults to
|
|
|
|
^(?<type>[^: ]+):(?<desc>.*?)(\[(?<ticket>[^\]]+)\])?$
|
|
|
|
The regular expression must capture a C<desc> field, and may
|
|
capture a C<type> and C<ticket> as well.
