This package contains Rake, a simple ruby build program with capabilities similar to make.
Rake has the following features:
Rakefiles (rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?)
Users can specify tasks with prerequisites.
Rake supports rule patterns to synthesize implicit tasks.
Flexible FileLists that act like arrays but know about manipulating file names and paths.
A library of prepackaged tasks to make building rakefiles easier. For example, tasks for building tarballs and publishing to FTP or SSH sites. (Formerly tasks for building RDoc and Gems were included in rake but they're now available in RDoc and RubyGems respectively.)
Supports parallel execution of tasks.
Download and install rake with the following.
gem install rake
First, you must write a “Rakefile” file which contains the build rules. Here's a simple example:
task :default => [:test] task :test do ruby "test/unittest.rb" end
This Rakefile has two tasks:
A task named “test”, which - upon invocation - will run a unit test file in Ruby.
A task named “default”. This task does nothing by itself, but it has exactly one dependency, namely the “test” task. Invoking the “default” task will cause Rake to invoke the “test” task as well.
Running the “rake” command without any options will cause it to run the “default” task in the Rakefile:
% ls Rakefile test/ % rake (in /home/some_user/Projects/rake) ruby test/unittest.rb ....unit test output here...
Type “rake –help” for all available options.

Rake is currently hosted at github. The github web page is github.com/jimweirich/rake . The public git clone URL is
If you wish to run the unit and functional tests that come with Rake:
Install the 'flexmock' gem
Install the 'session' gem in order to run the functional tests.
CD into the top project directory of rake.
Type one of the following:
rake # If you have a version of rake installed ruby -Ilib bin/rake # If you do not have a version of rake installed.

Rake is a late entry in the make replacement field. Here are links to other projects with similar (and not so similar) goals.
