Match Path Specifications, such as .gitignore, in Ruby!

Follows .gitignore syntax defined on gitscm

.gitignore functionality ported from Python pathspec by @cpburnz

gem install pathspec

➜ cat .gitignore
*.swp
/coverage/
➜ bundle exec pathspec-rb specs_match "coverage/foo"
/coverage/
➜ bundle exec pathspec-rb specs_match "file.swp"
*.swp
➜ bundle exec pathspec-rb match "file.swp"
➜ echo $?
0
➜ ls
Gemfile      Gemfile.lock coverage     file.swp     source.rb
➜ bundle exec pathspec-rb tree .

./file.swp

require 'pathspec'

# Create a .gitignore-style Pathspec by giving it newline separated gitignore
# lines, an array of gitignore lines, or any other enumable object that will
# give strings matching the .gitignore-style (File, etc.)
gitignore = PathSpec.from_filename('spec/files/gitignore_readme')

# Our .gitignore in this example contains:
# !**/important.txt
# abc/**

# true, matches "abc/**"
gitignore.match 'abc/def.rb'
# CLI equivalent: pathspec.rb -f spec/files/gitignore_readme match 'abc/def.rb'

# false, because it has been negated using the line "!**/important.txt"
gitignore.match 'abc/important.txt'
# CLI equivalent: pathspec.rb -f spec/files/gitignore_readme match 'abc/important.txt'

# Give a path somewhere in the filesystem, and the Pathspec will return all
# matching files underneath.
# Returns ['/src/repo/abc/', '/src/repo/abc/123']
gitignore.match_tree '/src/repo'
# CLI equivalent: pathspec.rb -f spec/files/gitignore_readme tree /src/repo

# Give an enumerable of paths, and Pathspec will return the ones that match.
# Returns ['/abc/123', '/abc/']
gitignore.match_paths ['/abc/123', '/abc/important.txt', '/abc/']
# There is no CLI equivalent to this.

This project uses mise for managing Ruby and bundler versions.

# macOS
brew install mise

# Other platforms: https://mise.jdx.dev/getting-started.html

Add to your shell profile (~/.zshrc, ~/.bashrc, etc.):

eval "$(mise activate zsh)"  # or bash, fish, etc.

# Install Ruby and bundler versions defined in .tool-versions
mise install

# Install gem dependencies
mise run install
# or: bundle install

# Run all tests (rubocop, unit tests, integration tests, docs)
mise run test
# or: bundle exec rake

# Run only unit tests
mise run test:unit
# or: bundle exec rake spec

# Run only integration tests
mise run test:integration
# or: bundle exec rake spec_integration

# Run all specs (unit + integration)
mise run test:all
# or: bundle exec rake spec_all

# Run tests across all Ruby versions (3.2, 3.3, 3.4, 4.0.1) using Docker
mise run test:matrix
# or: bundle exec rake test_matrix

# Build the gem
mise run build
# or: gem build pathspec.gemspec

The test:matrix task runs the full test suite across all supported Ruby versions in Docker containers, matching the CI environment. Integration tests cover the CLI executable (bin/pathspec-rb).

Pull requests, bug reports, and feature requests welcome! 😄 I've tried to write exhaustive tests but who knows what cases I've missed.

This is mainly a reminder to myself but the release process is:

1. Make sure CI is passing
2. Update the CHANGELOG with relevant changes to Gem consumers
3. Update version in gemspec with correct SemVer bump for scope of changes
4. Tag/release using GitHub UI and the Build & Push workflow should do the rest.
