1 == Git Library for Ruby
3 Library for using Git in Ruby.
7 The Ruby/Git homepage is currently at :
9 http://jointheconversation.org/rubygit
11 Git public hosting of the project source code is at:
13 http://repo.or.cz/w/rubygit.git
17 Right now I'm forking calls to the 'git' binary,
18 but eventually I'll replace that with either C bindings
19 to libgit or libgit-thin, or I'll write pure ruby
20 handlers for at least some of the Git stuff.
24 Git::Base - this is the object returned from a Git.open or Git.clone.
25 Most major actions are called from this object.
27 Git::Object - this is the base object for your tree, blob and commit objects,
28 returned from @git.gtree or @git.object calls. the Git::AbstractObject will
29 have most of the calls in common for all those objects.
31 Git::Diff - returns from a @git.diff command. It is an Enumerable that returns
32 Git::Diff:DiffFile objects from which you can get per file patches and insertion/deletion
33 statistics. You can also get total statistics from the Git::Diff object directly.
35 Git::Status - returns from a @git.status command. It is an Enumerable that returns
36 Git:Status::StatusFile objects for each object in git, which includes files in the working
37 directory, in the index and in the repository. Similar to running 'git status' on the command
38 line to determine untracked and changed files.
40 Git::Branches - Enumerable object that holds Git::Branch objects. You can call .local or .remote
41 on it to filter to just your local or remote branches.
43 Git::Remote - A reference to a remote repository that is tracked by this repository.
45 Git::Log - An Enumerable object that references all the Git::Object::Commit objects that encompass
46 your log query, which can be constructed through methods on the Git::Log object, like:
48 @git.log(20).object("HEAD^").since("2 weeks ago").between('v2.6', 'v2.7').each { |commit| [block] }
53 Here are a bunch of examples of how to use the Ruby/Git package.
55 First you have to remember to require rubygems if it's not. Then include the 'git' gem.
60 Here are the operations that need read permission only.
62 g = Git.open (working_dir = '.')
71 g.log # returns array of Git::Commit objects
72 g.log.since('2 weeks ago')
73 g.log.between('v2.5', 'v2.6')
74 g.log.each {|l| puts l.sha }
75 g.gblob('v2.5:Makefile').log.since('2 weeks ago')
77 g.object('HEAD^').to_s # git show / git rev-parse
78 g.object('HEAD^').contents
79 g.object('v2.5:Makefile').size
80 g.object('v2.5:Makefile').sha
87 commit = g.gcommit('1cc8667014381')
93 commit.author.date.strftime("%m-%d-%y")
95 commit.date.strftime("%m-%d-%y")
98 tree = g.gtree("HEAD^{tree}")
101 tree.children # blobs and subtrees
103 g.revparse('v2.5:Makefile')
105 g.branches # returns Git::Branch objects
108 g.branches[:master].gcommit
109 g.branches['origin/master'].gcommit
111 g.grep('hello') # implies HEAD
112 g.blob('v2.5:Makefile').grep('hello')
113 g.tag('v2.5').grep('hello', 'docs/')
115 g.diff(commit1, commit2).size
116 g.diff(commit1, commit2).stats
117 g.gtree('v2.5').diff('v2.6').insertions
118 g.diff('gitsearch1', 'v2.5').path('lib/')
119 g.diff('gitsearch1', @git.gtree('v2.5'))
120 g.diff('gitsearch1', 'v2.5').path('docs/').patch
121 g.gtree('v2.5').diff('v2.6').patch
123 g.gtree('v2.5').diff('v2.6').each do |file_diff|
126 puts file_diff.blob(:src).contents
129 g.config('user.name') # returns 'Scott Chacon'
130 g.config # returns whole config hash
132 g.tag # returns array of Git::Tag objects
136 And here are the operations that will need to write to your git repository.
141 Git.init('/home/schacon/proj',
142 { :git_dir => '/opt/git/proj.git',
143 :index_file => '/tmp/index'} )
145 g = Git.clone(URI, :name => 'name', :path => '/tmp/checkout')
146 g.config('user.name', 'Scott Chacon')
147 g.config('user.email', 'email@email.com')
150 g.add([file1, file2])
153 g.remove(['file.txt', 'file2.txt'])
156 g.commit_all('message')
158 g = Git.clone(repo, 'myrepo')
160 new_file('test-file', 'blahblahblah')
161 g.status.changed.each do |file|
162 puts file.blob(:index).contents
166 g.reset # defaults to HEAD
167 g.reset_hard(Git::Commit)
169 g.branch('new_branch') # creates new or fetches existing
170 g.branch('new_branch').checkout
171 g.branch('new_branch').delete
172 g.branch('existing_branch').checkout
174 g.checkout('new_branch')
175 g.checkout(g.branch('new_branch'))
177 g.branch(name).merge(branch2)
178 g.branch(branch2).merge # merges HEAD with branch2
180 g.branch(name).in_branch(message) { # add files } # auto-commits
181 g.merge('new_branch')
182 g.merge('origin/remote_branch')
183 g.merge(b.branch('master'))
184 g.merge([branch1, branch2])
186 r = g.add_remote(name, uri) # Git::Remote
187 r = g.add_remote(name, Git::Base) # Git::Remote
189 g.remotes # array of Git::Remotes
191 g.remote(name).remove
193 g.remote(name).merge(branch)
196 g.fetch(g.remotes.first)
199 g.pull(Git::Repo, Git::Branch) # fetch and a merge
201 g.add_tag('tag_name') # returns Git::Tag
206 g.push(g.remote('name'))
209 Some examples of more low-level index and tree operations
213 g.read_tree(tree3) # calls self.index.read_tree
214 g.read_tree(tree1, :prefix => 'hi/')
216 c = g.commit_tree('message')
219 c = g.commit_tree(t, :message => 'message', :parents => [sha1, sha2])
221 g.branch('branch_name').update_ref(c)
222 g.update_ref(branch, c)
224 g.with_temp_working do # new blank working directory
226 g.checkout(another_index)
227 g.commit # commits to temp_index
231 g.set_index('/path/to/index')
234 g.with_index(path) do
235 # calls set_index, then switches back after
238 g.with_working(dir) do
239 # calls set_working, then switches back after
242 g.with_temp_working(dir) do
243 g.checkout_index(:prefix => dir, :path_limiter => path)
245 g.commit # commits to index
