Git: creating and deleting a tag

Git has two kind of tags:

• annotated
• lightweight

Annotated tags are stored as full objects in the Git database. They’re checksummed; contain the tagger name, email, and date; have a tagging message; and can be signed and verified with GNU Privacy Guard (GPG)

The following command will create a (lightweight) tag:

Copygit tag v0.1

An annotated tag is created by:

Copygit tag -a v0.1 -m "a special tag message"

A normal git push will not push the tag. So in order to publish your (local) tags, you have to

Copygit push --tags

Check if a tag is annotated

You can use git show to see the annotation message of an annotated tag:

Copy$ git show v1.4
tag v1.4
Tagger: Some User <some@user.com>
Date:   Mon Oct 23 20:19:12 2017 +0200

my version 1.4

commit d24e7102ea99867e254c374c0d9bba5faf793b25
Author: Another User <another@user.com>
Date:   Sun Oct 22 12:52:11 2017 +0200

    changed the version number

Lightweigt tags obviously won't have an annotation message.

Remove a tag (local and remote)

To remove a tag on your work machine, use

Copygit tag -d v0.1

To also delete it from remote, you will have to do

Copygit push origin :refs/tags/v0.1

or

Copygit push origin -d v0.1
