Ruby/Git

Ruby/Git 是一个 Ruby 库可用来创建、操作 Git 资料库。它是通过封装了系统命令调用的方式实现的。

示例代码：

require 'rubygems'
require 'git'

g = Git.open(working_dir, :log => Logger.new(STDOUT))

g.index
g.index.readable?
g.index.writable?
g.repo
g.dir

g.log   # returns array of Git::Commit objects
g.log.since('2 weeks ago')
g.log.between('v2.5', 'v2.6')
g.log.each {|l| puts l.sha }
g.gblob('v2.5:Makefile').log.since('2 weeks ago')

g.object('HEAD^').to_s  # git show / git rev-parse
g.object('HEAD^').contents
g.object('v2.5:Makefile').size
g.object('v2.5:Makefile').sha

g.gtree(treeish)
g.gblob(treeish)
g.gcommit(treeish)


commit = g.gcommit('1cc8667014381')

commit.gtree
commit.parent.sha
commit.parents.size
commit.author.name
commit.author.email
commit.author.date.strftime("%m-%d-%y")
commit.committer.name
commit.date.strftime("%m-%d-%y")
commit.message

tree = g.gtree("HEAD^{tree}")

tree.blobs
tree.subtrees
tree.children # blobs and subtrees

g.revparse('v2.5:Makefile')

g.branches # returns Git::Branch objects
g.branches.local
g.branches.remote
g.branches[:master].gcommit
g.branches['origin/master'].gcommit

g.grep('hello')  # implies HEAD
g.blob('v2.5:Makefile').grep('hello')
g.tag('v2.5').grep('hello', 'docs/')

g.diff(commit1, commit2).size
g.diff(commit1, commit2).stats
g.gtree('v2.5').diff('v2.6').insertions
g.diff('gitsearch1', 'v2.5').path('lib/')
g.diff('gitsearch1', @git.gtree('v2.5'))
g.diff('gitsearch1', 'v2.5').path('docs/').patch
g.gtree('v2.5').diff('v2.6').patch

g.gtree('v2.5').diff('v2.6').each do |file_diff|
   puts file_diff.path
   puts file_diff.patch
   puts file_diff.blob(:src).contents
end

g.config('user.name')  # returns 'Scott Chacon'
g.config # returns whole config hash

g.tag # returns array of Git::Tag objects
