= RAKE -- Ruby Make
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 sythesize implicit tasks.
* Rake is lightweight. It can be distributed with other projects as a
single file. Projects that depend upon rake do not require that
rake be installed on target systems.
== Download
The latest version of rake can be found at
* http://rubyforge.org/project/showfiles.php?group_id=50
Online Resources can be found at ...
* Online Rake Documentation: http://rake.rubyforge.org
* Rake Project Page: http://rubyforge.org/projects/rake
* Rake Project Wiki: http://rake.rubyforge.org/wiki/wiki.pl
== Installation
=== Normal Installation
You can install rake with the following command.
% ruby install.rb
from its distribution directory.
=== GEM Installation
Download and install rake with the following.
gem install --remote rake
== Roadmap
* If you want to see how to invoke rake to build your projects, read on.
* If you want to see the format of a Rakefile, see
doc/rakefile.rdoc[http://rake.rubyforge.org/files/doc/rakefile_rdoc.html].
* If you want to see the original announcement of rake, see
doc/rational.rdoc[http://rake.rubyforge.org/files/doc/rational_rdoc.html].
* If you want to see a glossary of terms, see
doc/glossary.rdoc[http://rake.rubyforge.org/files/doc/glossary_rdoc.html].
== Simple Example
Once installed, you can run rake as follows ...
% rake [options ...] [VAR=VALUE ...] [tasks...]
Type "rake --help" for an up-to-date option summary.
Invoking <tt>rake</tt> without any options or targets causes rake to
look for a rakefile and invoke the default task in that rakefile.
For example, given a simple rakefile like this ...
task :default => [:test]
task :test do
ruby "test/unittest.rb"
end
The command
$ rake
will invoke the +default+ task. As +default+ satisfies its
prerequisites, the +test+ task will run the unit tests for the
package.
== Other Make Reinvisionings ...
Rake is a late entry in the make replacement field. Here are links to
other projects with similar (and not so similar) goals.
* http://www.a-a-p.org -- Make in Python
* http://www.aromatic.com/tools/jam.txt -- JAM, Java Automated Make
* http://ant.apache.org -- The Ant project
* http://www.perl.com/language/ppt/src/make/index.html -- Make from
the Perl Power Tools implementation.
== Credits
[<b>Ryan Dlugosz</b>] For the initial conversation that sparked Rake.
[<b>nobu.nokada@softhome.net</b>] For the initial patch for rule support.
[<b>Tilman Sauerbeck <tilman@code-monkey.de></b>] For the recursive rule patch.
== License
Rake is available under an MIT-style license.

== Support
The Rake homepage is http://rake.rubyforge.org. You can find the Rake
RubyForge page at http://rubyforge.org/projects/rake.
Feel free to submit commits or feature requests. If you send a patch,
remember to update the corresponding unit tests. If fact, I prefer
new feature to be submitted in the form of new unit tests.
For other information, feel free to ask on the ruby-talk mailing list
(which is mirrored to comp.lang.ruby) or contact
mailto:jim@weirichhouse.org.
----
= Usage
Rake is invoked from the command line using:
% rake [<em>options</em> ...] [<em>VAR</em>=<em>VALUE</em>] [<em>targets</em> ...]
Options are:
[<tt><em>name</em>=<em>value</em></tt>]
Set the environment variable <em>name</em> to <em>value</em>
during the execution of the <b>rake</b> command. You can access
the value by using ENV['<em>name</em>'].
[<tt>--dry-run</tt> (-n)]
Do a dry run. Print the tasks invoked and executed, but do not
actually execute any of the actions.
[<tt>--help</tt> (-H)]
Display some help text and exit.
[<tt>--libdir</tt> _directory_ (-I)]
Add _directory_ to the list of directories searched for require.
[<tt>--nosearch</tt> (-N)]
Do not search for a Rakefile in parent directories.
[<tt>--prereqs</tt> (-P)]
Display a list of all tasks and their immediate prerequisites.
[<tt>--quiet</tt> (-q)]
Do not echo commands from FileUtils.
[<tt>--rakefile</tt> _filename_ (-f)]
Use _filename_ as the name of the rakefile. The default rakefile
names are +rakefile+ and +Rakefile+ (with +rakefile+ taking
precedence). If the rakefile is not found in the current
directory, +rake+ will search parent directories for a match. The
directory where the Rakefile is found will become the current
directory for the actions executed in the Rakefile.
[<tt>--require</tt> _name_ (-r)]
Require _name_ before executing the Rakefile.
[<tt>--tasks</tt> (-T)]
Display a list of the major tasks and their comments. Comments
are defined using the "desc" command.
[<tt>--trace</tt> (-t)]
Turn on invoke/execute tracing. Also enable full backtrace on errors.
[<tt>--usage</tt> (-h)]
Display a usage message and exit.
[<tt>--verbose</tt> (-v)]
Echo the Sys commands to standard output.
[<tt>--version</tt> (-V)]
Display the program version and exit.
In addition, any command line option of the form
<em>VAR</em>=<em>VALUE</em> will be added to the environment hash
<tt>ENV</tt> and may be tested in the Rakefile.

= Rakefile Format
See doc/rakefile.rdoc[http://rake.rubyforge.org/files/doc/rakefile_rdoc.html]
