end
grep(string, path_limiter = nil, opts = {}) click to toggle source

will run a grep for 'string' on the HEAD of the git repository

to be more surgical in your grep, you can call grep() off a specific git object. for example:

@git.object("v2.3").grep('TODO')

in any case, it returns a hash of arrays of the type:

hsh[tree-ish] = [[line_no, match], [line_no, match2]]
hsh[tree-ish] = [[line_no, match], [line_no, match2]]

so you might use it like this:

@git.grep("TODO").each do |sha, arr|
  puts "in blob #{sha}:"
  arr.each do |match|
    puts "\t line #{match[0]}: '#{match[1]}'"
  end
end
# File lib/git/base.rb, line 237
def grep(string, path_limiter = nil, opts = {})
  self.object('HEAD').grep(string, path_limiter, opts)
end
gtree(objectish) click to toggle source
# File lib/git/base.rb, line 156
def gtree(objectish)
  Git::Object.new(self, objectish, 'tree')
end

# File lib/git/base.rb, line 201
def is_branch?(branch)
  branch_names = self.branches.map {|b| b.name}
  branch_names.include?(branch)
end
is_local_branch?(branch) click to toggle source

returns true if the branch exists locally

# File lib/git/base.rb, line 189

  branch_names = self.branches.local.map {|b| b.name}
  branch_names.include?(branch)
end
is_remote_branch?(branch) click to toggle source

returns true if the branch exists remotely

# File lib/git/base.rb, line 195
def is_remote_branch?(branch)
  branch_names = self.branches.local.map {|b| b.name}
  branch_names.include?(branch)
end
lib() click to toggle source

this is a convenience method for accessing the class that wraps all the actual 'git' forked system calls. At some point I hope to replace the Git::Lib class with one that uses native methods or libgit C bindings

# File lib/git/base.rb, line 214
def lib
  @lib ||= Git::Lib.new(self, @logger)
end
log(count = 30) click to toggle source

returns a Git::Log object with count commits

# File lib/git/base.rb, line 169

  Git::Log.new(self, count)
end

# File lib/git/base.rb, line 429
def ls_files(location=nil)

def ls_tree(objectish)
  self.lib.ls_tree(objectish)
end
merge(branch, message = 'merge') click to toggle source

merges one or more branches into the current working branch

you can specify more than one branch to merge by passing an array of branches

# File lib/git/base.rb, line 313
def merge(branch, message = 'merge')
  self.lib.merge(branch, message)
end
object(objectish) click to toggle source

returns a Git::Object of the appropriate type you can also call @git.gtree('tree'), but that's just for readability. If you call @git.gtree('HEAD') it will still return a Git::Object::Commit object.

@git.object calls a factory method that will run a rev-parse on the objectish and determine the type of the object and return an appropriate object for that type

# File lib/git/base.rb, line 152
def object(objectish)
  Git::Object.new(self, objectish)
end
pull(remote = 'origin', branch = 'master', message = 'origin pull') click to toggle source

fetches a branch from a remote and merges it into the current working branch

# File lib/git/base.rb, line 323
def pull(remote = 'origin', branch = 'master', message = 'origin pull')
  fetch(remote)
  merge(branch, message)
end
push(remote = 'origin', branch = 'master', tags = false) click to toggle source

pushes changes to a remote repository - easiest if this is a cloned repository, otherwise you may have to run something like this first to setup the push parameters:

@git.config('remote.remote-name.push', 'refs/heads/master:refs/heads/master')
# File lib/git/base.rb, line 306
def push(remote = 'origin', branch = 'master', tags = false)
  self.lib.push(remote, branch, tags)
end

def read_tree(treeish, opts = {})
  self.lib.read_tree(treeish, opts)
end
remote(remote_name = 'origin') click to toggle source

returns a Git::Remote object

# File lib/git/base.rb, line 207
def remote(remote_name = 'origin')
  Git::Remote.new(self, remote_name)
end
remotes() click to toggle source

returns an array of Git:Remote objects

# File lib/git/base.rb, line 329
def remotes
  self.lib.remotes.map { |r| Git::Remote.new(self, r) }
end
remove(path = '.', opts = {}) click to toggle source

removes file(s) from the git repository

# File lib/git/base.rb, line 252

  self.lib.reset(commitish, opts)
end
reset_hard(commitish = nil, opts = {}) click to toggle source

resets the working directory to the commitish with '--hard'

# File lib/git/base.rb, line 262
def reset_hard(commitish = nil, opts = {})
  opts = {:hard => true}.merge(opts)
  self.lib.reset(commitish, opts)
end

runs git rev-parse to convert the objectish to a full sha

# File lib/git/base.rb, line 459
