Description:

A ruby interface to Mercurial repositories, from the command line or a program.

Features/Problems:

• Supports Mercurial repositories completely!

Synopsis:

% amp add file.txt
edit...
% amp commit -m "updated the file"
% amp push

Nothing really changes from using the hg command. There are a few differences here and there (see amp help [COMMAND]), but really, it's pretty much the same.

Right now, we're trying to simplify the docs, to make it easier to tell what things are relevant to someone working with Amp. Most of our documentation is on our website, but here's an example of some Ampfile code:

command "stats" do |c|
  c.workflow :hg
  c.desc "Prints how many commits each user has contributed"
  c.on_run do |opts, args|
    repo = opts[:repository]
    users = Hash.new {|h, k| h[k] = 0}
    repo.each do |changeset|
      users[changeset.user.split("@").first] += 1
    end
    users.to_a.sort {|a,b| b[1] <=> a[1]}.each do |u,c|
      puts "#{u}: #{c}"
    end
  end
end

In the on_run handler, repo is a LocalRepository object. Its #each method iterates over ChangeSet objects, which store information about that particular commit, including which user committed it. These objects will be most relevant to users, but we'll try to make things more obvious as we refine our documentation. At the very least, we've tried to provide a useful description of every method we can.

Example:

---

% amp add file.txt edit... % amp commit -m "leethaxness" % amp push

Nothing really changes from using the hg command. There are a few differences here and there (see amp help [COMMAND]), but really, it's pretty much the same.

Using amp as a library:

require "amp" include Amp

repo = Repositories::pick "/Users/ari/src/amp.code" remote = Repositories::pick "https://user:password@bitbucket.org/carbonica/amp"

# makes a file... Dir.chdir "/Users/ari/src/amp.code/" open "testy.txt", "w" {|f| f.puts "hello, world!" }

# and add it to the repo! repo.add "testy.txt"

# commit repo.commit :message => 'blah'

# do some more things...

# pull and update... result = repo.pull remote result = repo.update if result.success?

(puts "You need to fix things!"; new_irb_session binding) unless result.success? # type result[:unresolved] to get a list of conflicts

# and push! repo.push remote

Everything here is really straight forward. Plus, if it's not, we've taken the liberty to document the motherfucking shit out of motherfucking everything. Hooray!
