# 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: - Inefficient evaluation: Programs are run using semi-naive evaluation strategies, but no further query optimization has been implemented, and little effort has been spent in tuning. - 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. MRI 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: % cd test; ruby ts_bud.rb ## Optional Dependencies The bud gem has a handful of mandatory dependencies. It also has two optional dependencies: if you wish to use Bud collections backed by Zookeeper or Tokyo Cabinet (the "zktable" and "tctable" collection types, respectively), the "zookeeper" and/or "tokyocabinet" gems must be installed. Note that before installing the "tokyocabinet" gem, the Tokyo Cabinet libraries should be installed first.
