Overview

On this page, we describe how to add tags to individual commits.

Tagging

Git allows you to tag a particular commit with an alphanumeric string for easy reference. This tag can be used with git pull, git checkout, etc. commands in the same way as for branches.

Each commit corresponding to a GEOS-Chem version release is tagged with the version number (e.g. 12.3.2).

Create a tag using Gitk

You may also add a tag via the gitk viewer utility, as follows:

(1) Start Gitk.

gitk --all

(2) Select the commit that you wish to tag by right-clicking on its name with your mouse. A context menu will appear:

(3) Select the Create tag option. A dialog box will appear:

(4) Type the text for your tag the Tag name box.

(5) Click on Create. Your tag should appear as a yellow flag in the Gitk revision history window.

Create a tag from the command line

You can add a tag via the command line:

    git tag GEOS-Chem TAG_NAME

That command will create a tag at the current commit.

Removing tags

You can remove a tag via the command line:

git tag -d TAG_NAME
