v

v

v is for versioned. It's is currently only a threaded wrapper for the git commands or procedures. In the future it should provide a generic interface for diverse VCSs.

This Project does not have a separate test suite. This projects version-tracks itself when everything works as expected.

All operations are designed to be reimplemented as pure ruby version and their interface is almost 1:1 mapped to their ruby derivate.

Install

gem install v

or unless you installed gemcutter

gem install gemcutter
gem tumble
gem install v

Interface

require 'v'

V.git do
  add '.'
  commit 'Initial commit!'
end

Git::Environment uses git returned by which git by default (*n*ix).

Change the git executable globally

V::Adapters::Git::Environment.which_git = '/usr/local/bin/git'

Change the git executable locally

env = V.git :which_git => '/usr/local/bin/git'

# or

V.git do
  @which_git = '/usr/local/bin/git'
  # ...
end

Working with futures...

V.git do
  # initialize repository and return environment (as future)
  init == self

  # add root to index return a index future
  proxy = add '.'
  # wait for result and return index
  proxy.value == index
  # shortcut for add '.'
  index == index << '.'

  # commit index and return commit future
  proxy = commit 'initial commit' 
  # wait for result and return commit
  commit = proxy.value

  # Queries:
  init.add('.').commit 'First argument is always the message!'
end

See auto_commit.rb for more examples.

Supported Operations

• add
• branch
• commit
• diff-index => diff_index (partially)
• init
• ls-files => ls_files (what does -v mean?)
• ls-tree => ls_tree (alias for args)
• push
• rm
• reset
• log (partially)
• show
• tag

Git Objects

• normal git objects
  • Blob
  • Commit
  • Tag
  • Tree
• convenience objects
  • Head
  • Index
  • Branch
  • Branches
  • Commits

TODO

• implement global cache / branch && git_dir flag expired by branch mtime
• implement non-blocking queries
• implement all git operations
• ALL operations should return raw results which can be used by the convenience objects
• implement Convenience objects (git objects call commands with arguments set, ...)
• add Documentation and Examples
• Long-Term: reimplement all ops in ruby, starting with plumbing

Note on Patches/Pull Requests

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.

Required

• git 1.6.3+
• fastthread

Thanks
