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.
