Get Labels Action

Get pull request or issue labels.

Why?

Usually the pull request or issue labels are available from the github context, like ${{ github.event.pull_request.labels }}, ${{ github.event.issue.labels }}. However, the github context is the one when the pull request or issue was created, so it does not include the label given during the CI test after creating the pull request.

This Action gets labels in real time.

Inputs

Name	Description	Default	Required
`number`	Pull request or issue number. Specify when changing from the default.	`${{ github.event.pull_request.number }}` or `${{ github.event.issue.number }}`	false
`repository`	Target repository name with owner, eg `snnaplab/get-labels-action`. Specify when accessing labels in a repository different from the workflow.	`${{ github.repository }}`	false
`github-token`	Specify a personal access token (PAT) when targeting a repository different from the workflow.	`${{ github.token }}`	false

Outputs

Name	Description
`labels`	Labels for pull requests or issues, in JSON format, eg `["bug","help wanted"]`.

The result is also stored in the environment variable LABELS.

Example

Run a step only if it contains a specific label

- uses: snnaplab/get-labels-action@v1
- if: contains(fromJSON(env.LABELS), 'bug')
  run: ...

Get label in bash

- uses: snnaplab/get-labels-action@v1
- run: |
    for i in $(seq 0 $(($(echo '${{ env.LABELS }}' | jq length) - 1)))
    do
      label=$(echo '${{ env.LABELS }}' | jq -r .[$i])
      ...
    done
