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.
22 Many of the simple read-only operations have already been
27 Git::Base - this is the object returned from a Git.open or Git.clone.
28 Most major actions are called from this object.
30 Git::Object - this is the base object for your tree, blob and commit objects,
31 returned from @git.gtree or @git.object calls. the Git::AbstractObject will
32 have most of the calls in common for all those objects.
34 Git::Diff - returns from a @git.diff command. It is an Enumerable that returns
35 Git::Diff:DiffFile objects from which you can get per file patches and insertion/deletion
36 statistics. You can also get total statistics from the Git::Diff object directly.
38 Git::Status - returns from a @git.status command. It is an Enumerable that returns
39 Git:Status::StatusFile objects for each object in git, which includes files in the working
40 directory, in the index and in the repository. Similar to running 'git status' on the command
41 line to determine untracked and changed files.
43 Git::Branches - Enumerable object that holds Git::Branch objects. You can call .local or .remote
44 on it to filter to just your local or remote branches.
46 Git::Remote - A reference to a remote repository that is tracked by this repository.
48 Git::Log - An Enumerable object that references all the Git::Object::Commit objects that encompass
49 your log query, which can be constructed through methods on the Git::Log object, like:
51 @git.log(20).object("HEAD^").since("2 weeks ago").between('v2.6', 'v2.7').each { |commit| [block] }
55 I have included a command line pure-ruby git client called 'gitr'
57 The following commands are available - they all will run in pure ruby, without forking out the the git binary.
58 In fact, they can be run on a machine without git compiled on it.
71 Here are a bunch of examples of how to use the Ruby/Git package.
73 First you have to remember to require rubygems if it's not. Then include the 'git' gem.
78 Here are the operations that need read permission only.
80 g = Git.open (working_dir, :log => Logger.new(STDOUT))
88 g.log # returns array of Git::Commit objects
89 g.log.since('2 weeks ago')
90 g.log.between('v2.5', 'v2.6')
91 g.log.each {|l| puts l.sha }
92 g.gblob('v2.5:Makefile').log.since('2 weeks ago')
94 g.object('HEAD^').to_s # git show / git rev-parse
95 g.object('HEAD^').contents
96 g.object('v2.5:Makefile').size
97 g.object('v2.5:Makefile').sha
104 commit = g.gcommit('1cc8667014381')
110 commit.author.date.strftime("%m-%d-%y")
111 commit.committer.name
112 commit.date.strftime("%m-%d-%y")
115 tree = g.gtree("HEAD^{tree}")
118 tree.children # blobs and subtrees
120 g.revparse('v2.5:Makefile')
122 g.branches # returns Git::Branch objects
125 g.branches[:master].gcommit
126 g.branches['origin/master'].gcommit
128 g.grep('hello') # implies HEAD
129 g.blob('v2.5:Makefile').grep('hello')
130 g.tag('v2.5').grep('hello', 'docs/')
132 g.diff(commit1, commit2).size
133 g.diff(commit1, commit2).stats
134 g.gtree('v2.5').diff('v2.6').insertions
135 g.diff('gitsearch1', 'v2.5').path('lib/')
136 g.diff('gitsearch1', @git.gtree('v2.5'))
137 g.diff('gitsearch1', 'v2.5').path('docs/').patch
138 g.gtree('v2.5').diff('v2.6').patch
140 g.gtree('v2.5').diff('v2.6').each do |file_diff|
143 puts file_diff.blob(:src).contents
146 g.config('user.name') # returns 'Scott Chacon'
147 g.config # returns whole config hash
149 g.tag # returns array of Git::Tag objects
153 And here are the operations that will need to write to your git repository.
158 Git.init('/home/schacon/proj',
159 { :git_dir => '/opt/git/proj.git',
160 :index_file => '/tmp/index'} )
162 g = Git.clone(URI, :name => 'name', :path => '/tmp/checkout')
163 g.config('user.name', 'Scott Chacon')
164 g.config('user.email', 'email@email.com')
167 g.add([file1, file2])
170 g.remove(['file.txt', 'file2.txt'])
173 g.commit_all('message')
175 g = Git.clone(repo, 'myrepo')
177 new_file('test-file', 'blahblahblah')
178 g.status.changed.each do |file|
179 puts file.blob(:index).contents
183 g.reset # defaults to HEAD
184 g.reset_hard(Git::Commit)
186 g.branch('new_branch') # creates new or fetches existing
187 g.branch('new_branch').checkout
188 g.branch('new_branch').delete
189 g.branch('existing_branch').checkout
191 g.checkout('new_branch')
192 g.checkout(g.branch('new_branch'))
194 g.branch(name).merge(branch2)
195 g.branch(branch2).merge # merges HEAD with branch2
197 g.branch(name).in_branch(message) { # add files } # auto-commits
198 g.merge('new_branch')
199 g.merge('origin/remote_branch')
200 g.merge(b.branch('master'))
201 g.merge([branch1, branch2])
203 r = g.add_remote(name, uri) # Git::Remote
204 r = g.add_remote(name, Git::Base) # Git::Remote
206 g.remotes # array of Git::Remotes
208 g.remote(name).remove
210 g.remote(name).merge(branch)
213 g.fetch(g.remotes.first)
216 g.pull(Git::Repo, Git::Branch) # fetch and a merge
218 g.add_tag('tag_name') # returns Git::Tag
223 g.push(g.remote('name'))
226 Some examples of more low-level index and tree operations
230 g.read_tree(tree3) # calls self.index.read_tree
231 g.read_tree(tree1, :prefix => 'hi/')
233 c = g.commit_tree('message')
236 c = g.commit_tree(t, :message => 'message', :parents => [sha1, sha2])
238 g.branch('branch_name').update_ref(c)
239 g.update_ref(branch, c)
241 g.with_temp_working do # new blank working directory
243 g.checkout(another_index)
244 g.commit # commits to temp_index
248 g.set_index('/path/to/index')
251 g.with_index(path) do
252 # calls set_index, then switches back after
255 g.with_working(dir) do
256 # calls set_working, then switches back after
259 g.with_temp_working(dir) do
260 g.checkout_index(:prefix => dir, :path_limiter => path)
262 g.commit # commits to index
