class Git::Base
Git::Base
is the main public interface for interacting with Git
commands.
Instead of creating a Git::Base
directly, obtain a Git::Base
instance by calling one of the follow {Git} class methods: {Git.open}, {Git.init}, {Git.clone}, or {Git.bare}.
Public Class Methods
(see Git.bare
)
# File lib/git/base.rb, line 14 def self.bare(git_dir, options = {}) normalize_paths(options, default_repository: git_dir, bare: true) self.new(options) end
(see Git.clone
)
# File lib/git/base.rb, line 20 def self.clone(repository, name, options = {}) new_options = Git::Lib.new(nil, options[:log]).clone(repository, name, options) normalize_paths(new_options, bare: options[:bare] || options[:mirror]) self.new(new_options) end
Returns (and initialize if needed) a Git::Config
instance
@return [Git::Config] the current config instance.
# File lib/git/base.rb, line 29 def self.config @@config ||= Config.new end
(see Git.init
)
# File lib/git/base.rb, line 34 def self.init(directory = '.', options = {}) normalize_paths(options, default_working_directory: directory, default_repository: directory, bare: options[:bare]) init_options = { :bare => options[:bare], :initial_branch => options[:initial_branch] } directory = options[:bare] ? options[:repository] : options[:working_directory] FileUtils.mkdir_p(directory) unless File.exist?(directory) # TODO: this dance seems awkward: this creates a Git::Lib so we can call # init so we can create a new Git::Base which in turn (ultimately) # creates another/different Git::Lib. # # TODO: maybe refactor so this Git::Bare.init does this: # self.new(opts).init(init_opts) and move all/some of this code into # Git::Bare#init. This way the init method can be called on any # repository you have a Git::Base instance for. This would not # change the existing interface (other than adding to it). # Git::Lib.new(options).init(init_options) self.new(options) end
Create an object that executes Git
commands in the context of a working copy or a bare repository.
@param [Hash] options The options for this command (see list of valid
options below)
@option options [Pathname] :working_dir the path to the root of the working
directory. Should be `nil` if executing commands on a bare repository.
@option options [Pathname] :repository used to specify a non-standard path to
the repository directory. The default is `"#{working_dir}/.git"`.
@option options [Pathname] :index used to specify a non-standard path to an
index file. The default is `"#{working_dir}/.git/index"`
@option options [Logger] :log A logger to use for Git
operations. Git
commands are logged at the `:info` level. Additional logging is done at the `:debug` level.
@return [Git::Base] an object that can execute git commands in the context
of the opened working copy or bare repository
# File lib/git/base.rb, line 88 def initialize(options = {}) if working_dir = options[:working_directory] options[:repository] ||= File.join(working_dir, '.git') options[:index] ||= File.join(options[:repository], 'index') end if options[:log] @logger = options[:log] @logger.info("Starting Git") else @logger = nil end @working_directory = options[:working_directory] ? Git::WorkingDirectory.new(options[:working_directory]) : nil @repository = options[:repository] ? Git::Repository.new(options[:repository]) : nil @index = options[:index] ? Git::Index.new(options[:index], false) : nil end
(see Git.open
)
# File lib/git/base.rb, line 61 def self.open(working_dir, options = {}) normalize_paths(options, default_working_directory: working_dir) self.new(options) end
Private Class Methods
Normalize options before they are sent to Git::Base.new
Updates the options parameter by setting appropriate values for the following keys:
* options[:working_directory] * options[:repository] * options[:index]
All three values will be set to absolute paths. An exception is that :working_directory will be set to nil if bare is true.
# File lib/git/base.rb, line 589 def self.normalize_paths( options, default_working_directory: nil, default_repository: nil, bare: false ) normalize_working_directory(options, default: default_working_directory, bare: bare) normalize_repository(options, default: default_repository, bare: bare) normalize_index(options) end
Normalize options
If working with a bare repository, set to the first non-nil value out of:
1. `options[:repository]` 2. the `default` parameter 3. the current working directory
Otherwise, set to the first non-nil value of:
1. `options[:repository]` 2. `.git`
Next, if options refers to a file and not a directory, set options to the contents of that file. This is the case when working with a submodule or a secondary working tree (created with git worktree add). In these cases the repository is actually contained/nested within the parent’s repository directory.
Finally, if options is a relative path, convert it to an absolute path relative to:
1. the current directory if working with a bare repository or 2. the working directory if NOT working with a bare repository
# File lib/git/base.rb, line 641 def self.normalize_repository(options, default:, bare: false) repository = if bare File.expand_path(options[:repository] || default || Dir.pwd) else File.expand_path(options[:repository] || '.git', options[:working_directory]) end if File.file?(repository) repository = File.expand_path(File.open(repository).read[8..-1].strip, options[:working_directory]) end options[:repository] = repository end
Normalize options
If working with a bare repository, set to ‘nil`. Otherwise, set to the first non-nil value of:
1. `options[:working_directory]`, 2. the `default` parameter, or 3. the current working directory
Finally, if options is a relative path, convert it to an absoluite path relative to the current directory.
# File lib/git/base.rb, line 608 def self.normalize_working_directory(options, default:, bare: false) working_directory = if bare nil else File.expand_path(options[:working_directory] || default || Dir.pwd) end options[:working_directory] = working_directory end
Public Instance Methods
updates the repository index using the working directory content
@example
git.add git.add('path/to/file') git.add(['path/to/file1','path/to/file2']) git.add(:all => true)
options:
:all => true
@param [String,Array] paths files paths to be added (optional, default=‘.’) @param [Hash] options @option options [boolean] :all
Update the index not only where the working tree has a file matching <pathspec> but also where the index already has an entry. See [the --all option to git-add](https://git-scm.com/docs/git-add#Documentation/git-add.txt--A) for more details.
# File lib/git/base.rb, line 247 def add(paths = '.', **options) self.lib.add(paths, options) end
adds a new remote to this repository url can be a git url or a Git::Base
object if it’s a local reference
@git.add_remote('scotts_git', 'git://repo.or.cz/rubygit.git') @git.fetch('scotts_git') @git.merge('scotts_git/master')
Options:
:fetch => true :track => <branch_name>
# File lib/git/base.rb, line 392 def add_remote(name, url, opts = {}) url = url.repo.path if url.is_a?(Git::Base) self.lib.remote_add(name, url, opts) Git::Remote.new(self, name) end
Creates a new git tag (Git::Tag)
@example
repo.add_tag('tag_name', object_reference) repo.add_tag('tag_name', object_reference, {:options => 'here'}) repo.add_tag('tag_name', {:options => 'here'})
@param [String] name The name of the tag to add @param [Hash] options Opstions to pass to ‘git tag`.
See [git-tag](https://git-scm.com/docs/git-tag) for more details.
@option options [boolean] :annotate Make an unsigned, annotated tag object @option options [boolean] :a An alias for the ‘:annotate` option @option options [boolean] :d Delete existing tag with the given names. @option options [boolean] :f Replace an existing tag with the given name (instead of failing) @option options [String] :message Use the given tag message @option options [String] :m An alias for the `:message` option @option options [boolean] :s Make a GPG-signed tag.
# File lib/git/base.rb, line 439 def add_tag(name, *options) self.lib.tag(name, *options) self.tag(name) end

creates an archive file of the given tree-ish
# File lib/git/base.rb, line 450 def archive(treeish, file = nil, opts = {}) self.object(treeish).archive(file, opts) end
# File lib/git/base.rb, line 568 def cat_file(objectish) self.lib.object_contents(objectish) end
changes current working directory for a block to the git working directory
example
@git.chdir do # write files @git.add @git.commit('message') end
# File lib/git/base.rb, line 114 def chdir # :yields: the Git::Path Dir.chdir(dir.path) do yield dir.path end end
checks out a branch as the new git working directory
# File lib/git/base.rb, line 328 def checkout(branch = 'master', opts = {}) self.lib.checkout(branch, opts) end
checks out an old version of a file
# File lib/git/base.rb, line 333 def checkout_file(version, file) self.lib.checkout_file(version,file) end
# File lib/git/base.rb, line 507 def checkout_index(opts = {}) self.lib.checkout_index(opts) end
cleans the working directory
options:
:force :d :ff
# File lib/git/base.rb, line 274 def clean(opts = {}) self.lib.clean(opts) end
commits all pending changes in the index file to the git repository
options:
:all :allow_empty :amend :author
# File lib/git/base.rb, line 315 def commit(message, opts = {}) self.lib.commit(message, opts) end
commits all pending changes in the index file to the git repository, but automatically adds all modified files without having to explicitly calling @git.add() on them.
# File lib/git/base.rb, line 322 def commit_all(message, opts = {}) opts = {:add_all => true}.merge(opts) self.lib.commit(message, opts) end
g.config(‘user.name’, ‘Scott Chacon’) # sets value g.config(‘user.email’, ‘email@email.com’) # sets value g.config(‘user.email’, ‘email@email.com’, file: ‘path/to/custom/config) # sets value in file g.config(’user.name’) # returns ‘Scott Chacon’ g.config # returns whole config hash
# File lib/git/base.rb, line 125 def config(name = nil, value = nil, options = {}) if name && value # set value lib.config_set(name, value, options) elsif name # return value lib.config_get(name) else # return hash lib.config_list end end
returns the name of the branch the working directory is currently on
# File lib/git/base.rb, line 573 def current_branch self.lib.branch_current end
deletes a tag
# File lib/git/base.rb, line 445 def delete_tag(name) self.lib.tag(name, {:d => true}) end
returns the most recent tag that is reachable from a commit
options:
:all :tags :contains :debug :exact_match :dirty :abbrev :candidates :long :always :match
# File lib/git/base.rb, line 293 def describe(committish=nil, opts={}) self.lib.describe(committish, opts) end
returns a reference to the working directory
@git.dir.path @git.dir.writeable?
# File lib/git/base.rb, line 141 def dir @working_directory end
iterates over the files which are unmerged
# File lib/git/base.rb, line 363 def each_conflict(&block) # :yields: file, your_version, their_version self.lib.conflicts(&block) end
fetches changes from a remote branch - this does not modify the working directory, it just gets the changes from the remote if there are any
# File lib/git/base.rb, line 339 def fetch(remote = 'origin', opts={}) self.lib.fetch(remote, opts) end
# File lib/git/base.rb, line 459 def gc self.lib.gc end
Run a grep for ‘string’ on the HEAD of the git repository
@example Limit grep’s scope by calling grep() from a specific object:
git.object("v2.3").grep('TODO')
@example Using grep results:
git.grep("TODO").each do |sha, arr| puts "in blob #{sha}:" arr.each do |line_no, match_string| puts "\t line #{line_no}: '#{match_string}'" end end
@return [Hash<String, Array>] a hash of arrays
```Ruby { 'tree-ish1' => [[line_no1, match_string1], ...], 'tree-ish2' => [[line_no1, match_string1], ...], ... } ```
# File lib/git/base.rb, line 224 def grep(string, path_limiter = nil, opts = {}) self.object('HEAD').grep(string, path_limiter, opts) end
returns reference to the git index file
# File lib/git/base.rb, line 146 def index @index end
returns true
if the branch exists
# File lib/git/base.rb, line 190 def is_branch?(branch) branch_names = self.branches.map {|b| b.name} branch_names.include?(branch) end
returns true
if the branch exists locally
# File lib/git/base.rb, line 178 def is_local_branch?(branch) branch_names = self.branches.local.map {|b| b.name} branch_names.include?(branch) end
returns true
if the branch exists remotely
# File lib/git/base.rb, line 184 def is_remote_branch?(branch) branch_names = self.branches.remote.map {|b| b.name} branch_names.include?(branch) end
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 198 def lib @lib ||= Git::Lib.new(self, @logger) end
# File lib/git/base.rb, line 529 def ls_files(location=nil) self.lib.ls_files(location) end
# File lib/git/base.rb, line 564 def ls_tree(objectish) self.lib.ls_tree(objectish) end
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 358 def merge(branch, message = 'merge', opts = {}) self.lib.merge(branch, message, opts) end
pulls the given branch from the given remote into the current branch
@git.pull # pulls from origin/master @git.pull('upstream') # pulls from upstream/master @git.pull('upstream', 'develope') # pulls from upstream/develop
# File lib/git/base.rb, line 373 def pull(remote='origin', branch='master') self.lib.pull(remote, branch) end
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 348 def push(remote = 'origin', branch = 'master', opts = {}) # Small hack to keep backwards compatibility with the 'push(remote, branch, tags)' method signature. opts = {:tags => opts} if [true, false].include?(opts) self.lib.push(remote, branch, opts) end
# File lib/git/base.rb, line 511 def read_tree(treeish, opts = {}) self.lib.read_tree(treeish, opts) end
returns an array of Git:Remote objects
# File lib/git/base.rb, line 378 def remotes self.lib.remotes.map { |r| Git::Remote.new(self, r) } end
removes file(s) from the git repository
# File lib/git/base.rb, line 252 def remove(path = '.', opts = {}) self.lib.remove(path, opts) end
removes a remote from this repository
@git.remove_remote(‘scott_git’)
# File lib/git/base.rb, line 412 def remove_remote(name) self.lib.remote_remove(name) end
repacks the repository
# File lib/git/base.rb, line 455 def repack self.lib.repack end
returns reference to the git repository directory
@git.dir.path
# File lib/git/base.rb, line 152 def repo @repository end
returns the repository size in bytes
# File lib/git/base.rb, line 157 def repo_size Dir.glob(File.join(repo.path, '**', '*'), File::FNM_DOTMATCH).reject do |f| f.include?('..') end.map do |f| File.expand_path(f) end.uniq.map do |f| File.stat(f).size.to_i end.reduce(:+) end
resets the working directory to the provided commitish
# File lib/git/base.rb, line 257 def reset(commitish = nil, opts = {}) self.lib.reset(commitish, opts) end
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
reverts the working directory to the provided commitish. Accepts a range, such as comittish..HEAD
options:
:no_edit
# File lib/git/base.rb, line 303 def revert(commitish = nil, opts = {}) self.lib.revert(commitish, opts) end
runs git rev-parse to convert the objectish to a full sha
@example
git.revparse("HEAD^^") git.revparse('v2.4^{tree}') git.revparse('v2.4:/doc/index.html')
# File lib/git/base.rb, line 560 def revparse(objectish) self.lib.revparse(objectish) end
# File lib/git/base.rb, line 167 def set_index(index_file, check = true) @lib = nil @index = Git::Index.new(index_file.to_s, check) end
sets the url for a remote url can be a git url or a Git::Base
object if it’s a local reference
@git.set_remote_url('scotts_git', 'git://repo.or.cz/rubygit.git')
# File lib/git/base.rb, line 403 def set_remote_url(name, url) url = url.repo.path if url.is_a?(Git::Base) self.lib.remote_set_url(name, url) Git::Remote.new(self, name) end
# File lib/git/base.rb, line 172 def set_working(work_dir, check = true) @lib = nil @working_directory = Git::WorkingDirectory.new(work_dir.to_s, check) end
Shows objects
@param [String|NilClass] objectish the target object reference (nil == HEAD) @param [String|NilClass] path the path of the file to be shown @return [String] the object information
# File lib/git/base.rb, line 478 def show(objectish=nil, path=nil) self.lib.show(objectish, path) end
# File lib/git/base.rb, line 524 def update_ref(branch, commit) branch(branch).update_ref(commit) end
