Print Workflow Data

Composite action that prints GitHub Actions context data for debugging. Outputs formatted, color-coded sections for github, matrix, job, runner contexts, plus optional caller-provided data.

Designed to run at the top of a workflow. Swallows errors to not fail workflows.

Usage

- uses: hwrok/print-workflow-data@v1

With optional inputs

- uses: hwrok/print-workflow-data@v1
  with:
    caller-inputs: ${{ toJSON(inputs) }}
    caller-needs: ${{ toJSON(needs) }}
    caller-vars: ${{ toJSON(vars) }}
    extras: ${{ toJSON(matrix) }}

Inputs

Input	Description	Required
caller-inputs	Workflow inputs — ${{ toJSON(inputs) }}	No
caller-needs	Job dependency results — ${{ toJSON(needs) }}	No
caller-vars	Repository/org variables — ${{ toJSON(vars) }}	No
extras	Any additional data, ideally as toJSON(...)	No

Output

JSON objects are automatically formatted as aligned key-value tables (requires jq on the runner, falls back to raw JSON otherwise).

Section headers are color-coded green in the actual workflow logs. Sections with no data display n/a.

Notes

• caller-vars exposes repository/org-level variables. Generally safe unless secrets have been stored as variables instead of secrets.
• extras accepts any string, but toJSON(...) format gets the nicest output.
• The action uses continue-on-error: true and exit 0 — it will never fail a calling workflow.
