Bud

This is Bud, a.k.a. "Bloom Under Development". It is an initial cut at a Bloom DSL, using Ruby as a setting.

See LICENSE for licensing information.

Language cheatsheet in docs/cheat.md ; see the docs/ directory for other documentation.

Main deficiencies at this point are:

  • No Ruby constraints: Within Bloom programs the full power of Ruby is also available, including mutable state. This allows programmers to get outside the Bloom framework and lose cleanliness.

  • Compatibility: Bud only works with Ruby (MRI) 1.8.7 and 1.9. JRuby and other Ruby implementations are currently not supported.

Installation

To install the latest release:

% gem install bud

To build and install a new gem from the current development sources:

% gem build bud.gemspec ; gem install bud*.gem

Note that GraphViz must be installed.

Simple example programs can be found in examples. A much larger set of example programs and libraries can be found in the bud-sandbox repository.

To run the unit tests:

% gem install minitest      # unless already installed
% cd test; ruby ts_bud.rb

To run the unit tests and produce a code coverage report:

% gem install simplecov    # unless already installed
% cd test; COVERAGE=1 ruby ts_bud.rb

Optional Dependencies

The bud gem has a handful of mandatory dependencies. It also has one optional dependency: if you wish to use Bud collections backed by Zookeeper, the "zookeeper" gem must be installed.

Something went wrong with that request. Please try again.
