The following action determines if a commit is a merge commit by inspecting the commits parent. If there is more than one commit then it returns true, otherwise false.
Only parameter needed is the SHA of the commit. This action is heavily reliant on the actions/checkout@v3 and the fetch-depth is a required field. If using the current commit the fetch-depth property should be at least set to 2. Otherwise it is recommended to fetch entire git history with fetch-depth: 0. Following is the example of the use of action.
on: [push]
jobs:
check_if_merge_commit_test:
runs-on: ubuntu-latest
name: Test merge commit
steps:
- uses: actions/checkout@v3
with:
# If not using current commit sha, set to 0
fetch-depth: 2
- id: test
uses: mmatotan/is-merge-commit@v0.5
with:
# Using current commit sha, but you can use any
github-sha: $GITHUB_SHA
# Use the steps.test.outputs.is-merge-commit to determine true/false
- run: echo ${{ steps.test.outputs.is-merge-commit }}
