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

Follows .gitignore syntax defined on gitscm

.gitignore functionality ported from Python pathspec by @cpburnz

Build/Install from Rubygems

gem install pathspec

CLI Usage

➜ 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 .
./coverage
./coverage/index.html
./file.swp

Usage

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.

Example Usage in Gemspec

lib = File.expand_path("lib", __dir__)
$LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib)
require "gemspec_pathspec_test/version"
require 'pathspec'

Gem::Specification.new do |spec|
  spec.name          = "gemspec_pathspec_test"
  spec.version       = GemspecPathspecTest::VERSION
  spec.authors       = ["Brandon High"]
  spec.email         = ["highb@users.noreply.github.com"]

  spec.summary = "whatever"

  spec.metadata["allowed_push_host"] = "TODO: Set to 'http://mygemserver.com'"

  ps = PathSpec.from_filename('.gitignore')
  spec.files         = Dir['lib/*.rb'].reject { |f| ps.match(f) }
  spec.bindir        = "exe"
  spec.executables   = spec.files.grep(%r{^exe/}) { |f| File.basename(f) }
  spec.require_paths = ["lib"]

  spec.add_development_dependency "bundler", "~> 2.0"
  spec.add_development_dependency "rake", "~> 10.0"
  spec.add_development_dependency "rspec", "~> 3.0"
end

Building/Installing from Source

cd pathspec-ruby && bash ./build_from_source.sh

Contributing

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

Releasing

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.
