Here’s a useful command that I’ve been using for a while. It generates a changelog, based on all merge commits since the latest release was tagged.
git log $(git describe –abbrev=0 –tags)..
–merges –pretty=format:”%b”
| grep -E ‘^[A-Z]+-[0-9]+’
If we break this down, we get to the following:
git describe –abbrev=0 –tags
This will give you the latest tag name, eg: 1.24.3. This value will be parsed in the git log command, as follows:
git log 1.24.3..
–merges –pretty=format:”%b”
| grep -E ‘^[A-Z]+-[0-9]+’
The flag --merges makes sure that only merge commits are included.--pretty-format:"%b" will limit the output from git log to only include the body of the merge commit. So given the following merge commit:
commit 5e15780ffad8ba4838e84916f64a2bbbf785f19b
Merge: db6e41a f1607b8
Author: Anse <john@doe.com>
Date: Tue Mar 27 15:08:07 2018 +0200
TICKET-3036: Ticket description goes here
It would output: TICKET-3036: Ticket description goes here
After that we’ll narrow down the output to only include lines that start with a ticket number, using grep -E '^[A-Z]+-[0–9]+'
