Bud v0.0.6 released

[Neil Conway]

Bud 0.0.6 has been released, and is available for download via RubyGems.

This release includes two primary fixes:

(1) Correctness fixes for the newly-introduced anti-join (negation)
syntax. Anyone using the `notin` syntax is strongly encouraged to
upgrade.

(2) Compatibility fixes for ruby2ruby 1.3.1. Specifically, ruby2ruby
1.3.1 has a bug which impacts Bud, so the 0.0.6 release depends on
ruby2ruby < 1.3.1.

The release also includes a bunch of other fixes, including:

* Change the behavior of BudCollection#schema. This previously
returned the column names of the collection as a list. Instead,
#schema will now return a hash: { key_col_names => non_key_col_names
}. The previous #schema behavior is available via BudCollection#cols.

* Reject import of modules that have already included the Bud module

* Disallow schemas containing "@" for non-channel collections

* Various budplot and visualization improvements

* Minor performance improvements

Good news,to expect the 1.0 version!

And have any plan to migrate to Scala@JVM as a DSL? For example ,like Orc language project(http://orc.csres.utexas.edu/).

Thanks.

We are actively discussing other language targets in our group, and are looking seriously at Scala and other JVM languages.

Roadmap for 1.0 is still wide open, but I expect it will include JRuby as well as language targets outside of Ruby. This will become more clear in coming months.

Thanks for your interest!

We recently discovered another bug in the anti-join code. That bug has
been fixed, and a new gem (v0.0.7) has been pushed to RubyGems with
the fix.
