Attributes

bare[R]

Public: The Boolean of whether or not the repo is bare.

git[RW]

Public Class Methods

init(path, git_options = {}, repo_options = {}) click to toggle source

Public: Initialize a git repository (create it on the filesystem). By default, the newly created repository will contain a working directory. If you would like to create a bare repo, use ::init_bare.

path - The String full path to the repo. Traditionally ends with

"/<name>.git".

git_options - A Hash of additional options to the git init command

(default: {}).

repo_options - A Hash of additional options to the ::new call

(default: {}).

Examples

Grit::Repo.init('/var/git/myrepo.git')

Returns the newly created Grit::Repo.

# File lib/grit/repo.rb, line 75
def self.init(path, git_options = {}, repo_options = {})
  git_options = {:base => false}.merge(git_options)
  git = Git.new(path)
  git.fs_mkdir('..')
  git.init(git_options, path)
  self.new(path, repo_options)
end
init_bare(path, git_options = {}, repo_options = {}) click to toggle source

Public: Initialize a bare git repository (create it on the filesystem).

path - The String full path to the repo. Traditionally ends with

"/<name>.git".

git_options - A Hash of additional options to the git init command

(default: {}).

repo_options - A Hash of additional options to the ::new call

(default: {}).

Examples

Grit::Repo.init_bare('/var/git/myrepo.git')

  self.new(path, repo_options)
end
init_bare_or_open(path, git_options = {}, repo_options = {}) click to toggle source

Public: Initialize a bare Git repository (create it on the filesystem) or, if the repo already exists, simply return it.

path - The String full path to the repo. Traditionally ends with

"/<name>.git".

git_options - A Hash of additional options to the git init command

(default: {}).

repo_options - A Hash of additional options to the ::new call

(default: {}).

Returns the new or existing Grit::Repo.

# File lib/grit/repo.rb, line 117

  end

  self.new(path, repo_options)
end
new(path, options = {}) click to toggle source

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.

# File lib/grit/repo.rb, line 40
