# mdtoc - Markdown Table of Contents [](https://github.com/andornaut/mdtoc/actions/workflows/release.yml) [](https://opensource.org/licenses/MIT) Read Markdown files and output a table of contents. ## Installation Requirements: * [Ruby](https://www.ruby-lang.org/en/) (see [.ruby-version](./.ruby-version)) ```bash gem install mdtoc ``` ## Usage ```bash mdtoc --help Usage: mdtoc [options] files or directories... -h, --help Show this message -o, --output PATH Update a table of contents in the file at PATH -a, --[no-]append Append to the --output file if a <!-- mdtoc --> tag isn't found -c, --[no-]create Create the --output file if it does not exist ``` 1. Add a `<!-- mdtoc -->` tag to a Markdown file. ```bash echo '<!-- mdtoc -->' >> README.md ``` 2. Run `mdtoc` and specify input files or directories (eg. the "test/samples" directory) and an output file (eg. "README.md"). ```bash mdtoc -aco README.md test/samples ``` ## Example Rakefile Create a `Rakefile` with the contents below, then run [`rake`](https://github.com/ruby/rake) to: * Run `mdtoc` to update the generated table of contents in the ./README.md file * `git add` any `*.md` files * Git commit, pull, and push any changes ```ruby task default: %w[mdtoc] desc 'Update Markdown table of contents and push changes to the git repository' task :mdtoc do command = <<~CMD set -e if [ -n "$(git diff --name-only --diff-filter=U)" ]; then echo 'Error: conflicts exist' >&2 exit 1 fi mdtoc --append --create --output README.md docs/ git add README.md docs/*.md git commit -qm 'Update TOC' || true git pull git push CMD sh command, verbose: false do |ok, status| unless ok fail "Failed with status: #{status.exitstatus}" end end end ``` See [andornaut/til](https://github.com/andornaut/til/blob/main/Rakefile) for an example. ## Developing ### Setup Requirements: * [Bundler](https://bundler.io/) * [chruby](https://github.com/postmodern/chruby) (recommended) ```bash # Setup development environment bin/setup ``` ### Tasks ```bash # List rake tasks rake -T rake build # Build gem into the pkg directory rake default # Run the build, rubocop, sorbet and test tasks rake install # Build and install gem into system gems rake rubocop # Run RuboCop rake sorbet # Run the Sorbet type checker rake test # Run tests # Run mdtoc with test inputs ruby -Ilib bin/mdtoc test/samples # Run mdtoc with test inputs, and write to a newly created output file f=$(mktemp) && ruby -Ilib bin/mdtoc -aco ${f} test/samples ; cat ${f} ``` ### Publishing 1. Bump version in `lib/mdtoc/version.rb` 2. Run `bundle install` to update `Gemfile.lock` 3. Commit the changes 4. Tag the commit `vX.Y.Z` and push the tag Pushing the tag is the whole release. The Release workflow runs the checks, builds the gem, cuts the GitHub release, and pushes that same gem to RubyGems. `rake release` is not run by hand. Nothing here holds a RubyGems API key. The workflow authenticates with a short-lived credential minted from its own OIDC claim, against a trusted publisher registered on RubyGems that names this repository and `.github/workflows/release.yml`. Renaming that file stops publishing until the trusted publisher is updated to match.
