Git Kata: Tagging of the commits

Setup:

1. Run source setup.sh (or .\setup.ps1 in PowerShell)

Motivation

Tags are convenient for keeping track of commits that bump a version number. One way of using them is together with branches, where we can tag commits in a branch if they bump the version number, e.g., a branch called version/1.1 can have the tags 1.1.1, 1.1.2 etc. Tags can also be used without branches.

There are two types of tags, annotated tags and unannotated tags. Annotated tags can contain additional information, i.e., you could add some log output, in addition to the name. Apart from annotated tags, you can create unannotated tags that just have the name. In some cases, tags with no annotations work well, because the tag name and the changes of the commit contain the necessary information.

The task

For simplicity, we will just work with the master branch in this kata. A couple of tags are already created.

1. See which tags that were created.
2. Make a new commit, and introduce a new annotated tag.
3. We made a couple of commits. Can you add a tag to an arbitrary commit?
4. The exercise repository contains an annotated tag. What's the message?
5. Maybe not all of the tags are needed. Delete some of them.

Useful commands

• git tag
• git tag -d <tag>
• git tag --list <pattern>
• git push --tags <branch>
• git rev-parse <tag>
