Constructor Details

#initialize(path, options = {}) ⇒ Repo

Public: Create a new Repo instance.

path - The String path to either the root git directory or the bare

git repo. Bare repos are expected to end with ".git".

options - A Hash of options (default: {}):

:is_bare - Boolean whether to consider the repo as bare even
           if the repo name does not end with ".git".

Examples

r = Repo.new("/Users/tom/dev/normal")
r = Repo.new("/Users/tom/public/bare.git")
r = Repo.new("/Users/tom/public/bare", {:is_bare => true})

Returns a newly initialized Grit::Repo. Raises Grit::InvalidGitRepositoryError if the path exists but is not

a Git repository.

Raises Grit::NoSuchPathError if the path does not exist.

#recent_tag_name(committish = nil, options = {}) ⇒ Object

Finds the most recent annotated tag name that is reachable from a commit.

@repo.recent_tag_name('master')
# => "v1.0-0-abcdef"

committish - optional commit SHA, branch, or tag name. options - optional hash of options to pass to git.

Default: {:always => true}
:tags => true      # use lightweight tags too.
:abbrev => Integer # number of hex digits to form the unique
  name.  Defaults to 7.
:long => true      # always output tag + commit sha
# see `git describe` docs for more options.

Returns the String tag name, or just the commit if no tag is found. If there have been updates since the tag was made, a suffix is added with the number of commits since the tag, and the abbreviated object name of the most recent commit. Returns nil if the committish value is not found.
