Action docs

A CLI to generate and update documentation for GitHub actions or workflows, based on the definition .yml. To update your README in a GitHub workflow you can use the action-docs-action.

TL;DR

Add the following comment blocks to your README.md

1<!-- action-docs-header source="action.yml" -->
2
3<!-- action-docs-description source="action.yml" --> # applicable for actions only
4
5<!-- action-docs-inputs source="action.yml" -->
6
7<!-- action-docs-outputs source="action.yml" -->
8
9<!-- action-docs-runs source="action.yml" --> # applicable for actions only

Optionally you can also add the following section to generate a usage guide, replacing <project> and <version> with the name and version of your project you would like to appear in your usage guide.

1<!-- action-docs-usage source="action.yml" project="<project>" version="<version>" -->

Update the README

Action-docs can update your README based on the action.yml. The following sections can be updated: name header, description, inputs, outputs, usage, and runs. Add the following tags to your README and run action-docs -u.

1<!-- action-docs-header source="action.yml" -->
2
3<!-- action-docs-description source="action.yml" -->
4
5<!-- action-docs-inputs source="action.yml" -->
6
7<!-- action-docs-outputs source="action.yml" -->
8
9<!-- action-docs-runs action="action.yml" -->
10
11<!-- action-docs-usage action="action.yml" project="<project>" version="<version>" -->

Or to include all of the above, use:

1<!-- action-docs-all source="action.yml" project="<project>" version="<version>" -->

For updating other Markdown files add the name of the file to the command action-docs -u <file>.

If you need to use another/action.yml:

1. write it in tags like source="another/action.yml";
2. specify in a command via the -s option like action-docs -s another/action.yml
