| github-actions_dump-context.md | github-actions | Dump out all GitHub Actions context | https://github.com/simonw/til/blob/main/github-actions/dump-context.md | Useful for seeing what's available for `if: ` conditions (see [context and expression syntax](https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions)). I copied this example action [from here](https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions#example-printing-context-information-to-the-log-file) and deployed it [here](https://github.com/simonw/playing-with-actions/blob/master/.github/workflows/dump-context.yml). Here's an [example run](https://github.com/simonw/playing-with-actions/runs/599575180?check_suite_focus=true). ```yaml on: push jobs: one: runs-on: ubuntu-16.04 steps: - name: Dump GitHub context env: GITHUB_CONTEXT: ${{ toJson(github) }} run: echo "$GITHUB_CONTEXT" - name: Dump job context env: JOB_CONTEXT: ${{ toJson(job) }} run: echo "$JOB_CONTEXT" - name: Dump steps context env: STEPS_CONTEXT: ${{ toJson(steps) }} run: echo "$STEPS_CONTEXT" - name: Dump runner context env: RUNNER_CONTEXT: ${{ toJson(runner) }} run: echo "$RUNNER_CONTEXT" - name: Dump strategy context env: STRATEGY_CONTEXT: ${{ toJson(strategy) }} run: echo "$STRATEGY_CONTEXT" - name: Dump matrix context env: MATRIX_CONTEXT: ${{ toJson(matrix) }} run: echo "$MATRIX_CONTEXT" ``` | <p>Useful for seeing what's available for <code>if: </code> conditions (see <a href="https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions">context and expression syntax</a>).</p> <p>I copied this example action <a href="https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions#example-printing-context-information-to-the-log-file">from here</a> and deployed it <a href="https://github.com/simonw/playing-with-actions/blob/master/.github/workflows/dump-context.yml">here</a>.
