Adding GitHub labels using the gh CLI

A short guide and template for GitHub issue labels

Basic notes and template for creating labels for GitHub issues using the gh command line tool.

Jump directly to the new label template.

Introduction

This post is mostly about one command. Specifically, it's about one sub-command available with the gh CLI tool: gh label create. It's not because I think that it's a particularly interesting or complicated command. It's mostly because I rarely use the command infrequently and I need a reference for the "standard" that I have casually set up for myself. I work with git and gh commands daily. Many have been successfully committed to muscle memory. With other lengthy gh commands, I've turned a few of them into memorable aliases. I should probably make use of gh alias set; but, that's for another day.

As stated in GitHub's documentation on managing labels:

You can manage your work on GitHub by creating labels to categorize issues, pull requests, and discussions. You can apply labels in the repository the label was created in. Once a label exists, you can use the label on any issue, pull request, or discussion within that repository.

I only use the gh label create command when I create a new repository. The time between creating a new project varies from anywhere between a couple of weeks and several months. So, naturally, I tend to forget commands that haven't entered my muscle memory. With my projects using Python web frameworks, I've mostly standardized on my issue labels and can use the gh label clone command for these projects.

The GitHub organizations feature could also help facilitate the management of default labels across repositories. I, personally, have no plans on using it for now; but, it may be of use for some.

gh CLI label syntax

From the gh CLI manual:

  • USAGE

    • gh label [flags]
  • AVAILABLE COMMANDS

    • clone: Clones labels from one repository to another
    • create: Create a new label
    • delete: Delete a label from a repository
    • edit: Edit a label
    • list: List labels in a repository
  • FLAGS

    • -R, --repo [HOST/]OWNER/REPO Select another repository using the [HOST/]OWNER/REPO format

gh label create command format

gh label create <name> [flags]
gh label create <name> -d "description_string" -c "color_string"

Interlude: Color Selection

According to the gh manual, the label color needs to be specified as a six character hex value. Despite my working in desktop publishing and pre-press in a prior life, I don't have many hex color values memorized; so, I tend to rely on a color chart or a color picker application to help me in my color decisions. The availability of color charts and hex color codes on the internet is abundant. Plentiful even. There must be at least 10 color charts available online for reference. Here are two that I use frequently:

I'm also partial to using a locally installed color picker application. I've been using gcolor3 lately. It's simple and meets my basic needs. For alternatives, here is an OK list of other color picker applications available on Linux distros for installation:

Default Issue Labels

Label Name Description Color
bug Something isn't working #d73a4a
documentation Improvements/additions to documentation #0075ca
duplicate This issue or pull request already exists #cfd3d7
enhancement New feature of request #a2eeef
help wanted Extra attention is needed #008672
good first issue Good for newcomers #7057ff
invalid This doesn't seem right #e4e669
question Further information is requested #d876e3
wontfix This will not be worked on #ffffff

New Issue Labels

Label Name Description Color
build system Issues related to building and packaging #f95f13
deployment project release & publishing #52794f
performance Issues related to application performance #cb738a
security bug reports, fixes, vulnerability issues #7057ff
testing project testing & validation #5319e7

Cloning labels from another project

If there is a repository that has a set of labels that can be used as a template for a new project, one can clone all of its existing labels to the new project with the command:

gh label clone -f kevinbowen777/django-start

Issue Label Examples

If you want to be selective, the labels can be individually added as follows:

gh label create "build system" -c F95F13 -d "Issues related to building, packaging"
gh label create deployment -c 52794F -d "project release & publishing"
gh label create performance -c CB738A -d "Issues related to application performance"
gh label create security -c 7057ff -d "bug reports, fixes, vulnerability issues"
gh label create testing -c 5319e7 -d "project testing & validation"

Other examples of gh label usage

As you can see, my usage of issue labels is pretty simple. Here are a couple of examples of label usage in more complex projects:

gh aliases

Some frequently used gh commands that I have converted to bash aliases:

alias ghicb='gh issue create --label bug --assignee @me'
alias ghicd='gh issue create --label documentation --assignee @me'
alias ghice='gh issue create --label enhancement --assignee @me'
alias ghict='gh issue create --label testing --assignee @me'
alias ghil='gh issue list --limit 100'
