Rant is a flexible build tool written entirely in Ruby.
The equivalent to a Makefile for make is the Rantfile. An Rantfile is actually a valid Ruby script that is read in by the rant command.
Rant currently features:
Rantfiles are written in Ruby.
Defining custom tasks
Automated packaging, testing and RDoc generation for Ruby applications and libraries.
The rant-import command creates a monolithic rant script, so you don’t depend on an rant installation anymore.
Creating gzipped tar and zip archives – without installing additional software.
Optional recognition of file changes based on MD5 checksums instead of file modification times.
Tasks with command change recognition.
Dependency checking for C/C++ source files.
As programmers usually want to see code, here is a short and very basic example of rant usage:
A file called Rantfile contains the code:
file "backup/data" => "data" do |t|
sys.cp t.source, t.name
end
Running rant in the directory of this file:
% rant
cp data backup/data
will ensure that the “data” file in the “backup” directory is up to date.
This document was written for version 0.5.6 of Rant. Most things described here will work for older/newer versions of Rant, but look at the README file in the Rant distribution you’ve installed for exact documentation of your Rant version.
SupportThe newest version of this document can be found at make.rubyforge.org.

Rant was started in February 2005. It has been written and is maintained by Stefan Lang ([email protected]).
CreditsRant has taken the basic syntax of a task and some other concepts from Rake. So thanks to Jim Weirich, the author of Rake.
Rant comes with parts of archive-tar-minitar to create (gzipped) tar archives on platforms where no tar command is available. archive-tar-minitar is developed by Mauricio Julio Fernandez Pradier and Austin Ziegler.
Rant comes with parts of rubyzip to create zip archives on platforms where no zip command is available. rubyzip is developed by Thomas Sondergaard.
Most important is to be a very flexible build tool. This currently means that you can run/use Rant in many different ways. E.g. you can invoke it the conventional way like make, define tasks and run Rant from irb (the interactive Ruby shell), create an independent script with rant-import, or simply use Rant as a library to automate tasks for your application.
Extensible: currently through plugins and generators. (Think of the plugin and import functions.)
Portability: see Platforms below for details
Well scaling: Rant should work acceptable for bigger projects (from a performance POV and for the writer of the Rantfiles).
Rant was tested on:
System Ruby version
=======================================================
Linux 1.8.0
1.8.1
1.8.2
1.8.3 1.8.4 1.9
MacOS X 1.8.2
Windows XP 1.8.2 (OneClick Installer)
Windows XP 1.8.4 (OneClick Installer)
Windows 2000 1.8.2 (OneClick Installer)
It should run on most platforms where Ruby runs, but you never know…
If you encounter problems with Rant on any platform (with Ruby 1.8.0 or higher) please write a bugreport!
Why did you write another build tool?Because I wasn’t satisfied by any other build tool. Before I started Rant, I had to write a program in C#. The program had to run under Windows, but I wanted to develop under Linux. Also I decided to write the documentation in Docbook.
So there where quite a few problems arising:
I had to compile with cscc on Linux.
compile with csc on Windows.
automate PDF and HTML generation from Docbook
Nant would have been ok to compile the C# sources. But it isn’t suited for more general tasks as clueing togheter other programs (needed for Docbook processing).
Then I tried to use Rake and it was the other way round. I liked the basic concept and syntax of Rake and of course I could have written code for Rake (e.g. with a so called Tasklib) to support portable C# compilation. But it was a bit quirky and because I like to work with Ruby, I decided to write my own build tool.
