Prototype Bud runtime (Bloom Under Development)

README.md

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. Bud also has experimental support for Ruby 2.0. 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.
