Prolog for Ruby (ruby-prolog) Updated, Hits v1.0.1

After a long period of inactivity I’ve updated the F/OSS ruby-prolog gem! It’s been updated for ruby 2.0.0, bundler, and minitest, and released as v1.0.1!

ruby-prolog allows you to solve complex logic problems on the fly using a dynamic, Prolog-like DSL. Basic use is encompassed by stating basic facts using your data, defining rules, and then asking questions. Why is this cool? Because ruby-prolog allows you to leave your normal object-oriented vortex on demand and step into the alternate reality of declarative languages.

With ruby-prolog:

  • There are no classes.
  • There are no functions.
  • There are no variables.
  • There are no control flow statements.

You can use all these wonder things — it’s still Ruby after all — but they’re not needed, and mainly useful for getting data and results into/out of the interpreter. Prolog still tends to be favored heavily in artificial intelligence and theorem proving applications and is still relevant to computer science curricula as well, so I hope this updated release proves useful to the Ruby community.

Check out a simple ACL enforcement example or, for the daring, the ruby-prolog solution to the Tower’s of Hanoi problem!

From the TGen website:

At TGen, investigators are pushing the limits of cutting-edge research and technology to discover the genetic cause of disease. Experiments that were impossible and impractical only a few years ago are now conducted every day.

Discovery fuels TGen’s translational research and lies at the heart of our scientific investigations. TGen’s research divisions are designed to foster a wide range of genetic discoveries. These divisions draw heavily upon TGen’s scientific platforms to expedite findings. TGen’s labs are staffed by teams of researchers focused on making genomic discoveries in common diseases and disorders in the areas of oncology, neurogenomics and metabolic disease.
