grit
- by FIX (your name)
- FIX (url)
+ by Tom Preston-Werner
+ grit.rubyforge.org
== DESCRIPTION:
+
+Grit is a Ruby library for extracting information from a git repository in and
+object oriented manner.
+
+== REQUIREMENTS:
+
+* git (http://git.or.cz) tested with 1.5.3.4
+
+== INSTALL:
+
+sudo gem install grit
+
+== USAGE:
+
+Grit gives you object model access to your git repository. Once you have
+created a repository object, you can traverse it to find parent commit(s),
+trees, blobs, etc.
+
+= Initialize a Repo object
+
+The first step is to create a GitPython.Repo object to represent your repo. I
+include the Grit module so reduce typing.
+
+ include Grit
+ repo = Repo.new("/Users/tom/dev/grit")
-FIX (describe your package)
+In the above example, the directory /Users/tom/dev/grit is my working
+repo and contains the .git directory. You can also initialize Grit with a
+bare repo.
-== FEATURES/PROBLEMS:
+ repo = Repo.new("/var/git/grit.git")
-* FIX (list of features or problems)
+= Getting a list of commits
-== SYNOPSIS:
+From the Repo object, you can get a list of commits as an array of Commit
+objects.
- FIX (code sample of usage)
+ repo.commits
+ # => [#<GitPython.Commit "e80bbd2ce67651aa18e57fb0b43618ad4baf7750">,
+ #<GitPython.Commit "91169e1f5fa4de2eaea3f176461f5dc784796769">,
+ #<GitPython.Commit "038af8c329ef7c1bae4568b98bd5c58510465493">,
+ #<GitPython.Commit "40d3057d09a7a4d61059bca9dca5ae698de58cbe">,
+ #<GitPython.Commit "4ea50f4754937bf19461af58ce3b3d24c77311d9">]
+
+Called without arguments, Repo#commits returns a list of up to ten commits
+reachable by the master branch (starting at the latest commit). You can ask
+for commits beginning at a different branch, commit, tag, etc.
-== REQUIREMENTS:
+ repo.commits('mybranch')
+ repo.commits('40d3057d09a7a4d61059bca9dca5ae698de58cbe')
+ repo.commits('v0.1')
+
+You can specify the maximum number of commits to return.
-* FIX (list of requirements)
+ repo.commits('master', 100)
+
+If you need paging, you can specify a number of commits to skip.
-== INSTALL:
+ repo.commits('master', 10, 20)
+
+The above will return commits 21-30 from the commit list.
+
+= The Commit object
+
+Commit objects contain information about that commit.
+
+ head = repo.commits.first
+
+ head.id
+ # => "e80bbd2ce67651aa18e57fb0b43618ad4baf7750"
+
+ head.parents
+ # => [#<GitPython.Commit "91169e1f5fa4de2eaea3f176461f5dc784796769">]
+
+ head.tree
+ # => #<GitPython.Tree "3536eb9abac69c3e4db583ad38f3d30f8db4771f">
+
+ head.author
+ # => #<GitPython.Actor "Tom Preston-Werner <tom@mojombo.com>">
+
+ head.authored_date
+ # => Wed Oct 24 22:02:31 -0700 2007
+
+ head.committer
+ # => #<GitPython.Actor "Tom Preston-Werner <tom@mojombo.com>">
+
+ head.committed_date
+ # => Wed Oct 24 22:02:31 -0700 2007
+
+ head.message
+ # => "add Actor inspect"
+
+You can traverse a commit's ancestry by chaining calls to #parents.
+
+ repo.commits.first.parents[0].parents[0].parents[0]
+
+The above corresponds to master^^^ or master~3 in git parlance.
+
+= The Tree object
+
+A tree records pointers to the contents of a directory. Let's say you want
+the root tree of the latest commit on the master branch.
+
+ tree = repo.commits.first.tree
+ # => #<GitPython.Tree "3536eb9abac69c3e4db583ad38f3d30f8db4771f">
+
+ tree.id
+ # => "3536eb9abac69c3e4db583ad38f3d30f8db4771f"
+
+Once you have a tree, you can get the contents.
+
+ contents = tree.contents
+ # => [#<GitPython.Blob "4ebc8aea50e0a67e000ba29a30809d0a7b9b2666">,
+ #<GitPython.Blob "81d2c27608b352814cbe979a6acd678d30219678">,
+ #<GitPython.Tree "c3d07b0083f01a6e1ac969a0f32b8d06f20c62e5">,
+ #<GitPython.Tree "4d00fe177a8407dbbc64a24dbfc564762c0922d8">]
+
+This tree contains two Blob objects and two Tree objects. The trees are
+subdirectories and the blobs are files. Trees below the root have additional
+attributes.
+
+ contents.last.name
+ # => "lib"
+
+ contents.last.mode
+ # => "040000"
+
+There is a convenience method that allows you to get a named sub-object
+from a tree.
+
+ tree/"lib"
+ # => #<GitPython.Tree "e74893a3d8a25cbb1367cf241cc741bfd503c4b2">
+
+You can also get a tree directly from the repo if you know its name.
+
+ repo.tree
+ # => #<GitPython.Tree "master">
+
+ repo.tree("91169e1f5fa4de2eaea3f176461f5dc784796769")
+ # => #<GitPython.Tree "91169e1f5fa4de2eaea3f176461f5dc784796769">
+
+= The Blob object
+
+A blob represents a file. Trees often contain blobs.
+
+ blob = tree.contents.first
+ # => #<GitPython.Blob "4ebc8aea50e0a67e000ba29a30809d0a7b9b2666">
+
+A blob has certain attributes.
+
+ blob.id
+ # => "4ebc8aea50e0a67e000ba29a30809d0a7b9b2666"
+
+ blob.name
+ # => "README.txt"
+
+ blob.mode
+ # => "100644"
+
+ blob.size
+ # => 7726
+
+You can get the data of a blob as a string.
+
+ blob.data
+ # => "Grit is a library to ..."
+
+You can also get a blob directly from the repo if you know its name.
-* FIX (sudo gem install, anything else)
