watchr

Summary

Agile development tool that monitors a directory tree, and triggers a user defined action whenever an observed file is modified. Its most typical use is continuous testing, and as such it is a more flexible alternative to autotest.

Features

watchr is:

• Simple to use
• Highly flexible
• Evented ( Listens for filesystem events with native c libs )
• Portable ( Linux, *BSD, OSX, Solaris, Windows )
• Fast ( Immediately reacts to file changes )

Most importantly it allows running tests in an environment that is agnostic to:

• Web frameworks ( rails, merb, sinatra, camping, invisible, ... )
• Test frameworks ( test/unit, minitest, rspec, test/spec, expectations, ... )
• Ruby interpreters ( ruby1.8, ruby1.9, MRI, JRuby, Rubinius, ... )
• Package frameworks ( rubygems, rip, ... )

Usage

On the command line,

$ watchr path/to/script.file

will monitor files in the current directory tree, and react to events on those files in accordance with the script.
