Plugin: generator-changelog-html

Name: semrel
Author: SemRels

Generates an HTML changelog from the release context and commit history. Running as a generator phase plugin, its stdout overrides the default SEMREL_CHANGELOG value that provider and hook plugins receive — useful for platforms that accept HTML release descriptions.

Installation

semrel plugin install @semrel/generator-changelog-html

Configuration

plugins:
  - uses: @semrel/generator-changelog-html
    phase: generator          # stdout captured by semrel → becomes SEMREL_CHANGELOG
    args:
      template: .semrel/templates/changelog.html.tmpl   # optional
      css_file: .semrel/templates/changelog.css          # optional

      max_commits: "100"
  - uses: @semrel/provider-github     # receives the HTML as SEMREL_CHANGELOG
