P4Ruby is a wrapper for the P4 C++ API in Ruby.

P4Ruby is a Ruby module that provides an object-oriented API to Helix Core server. Using P4Ruby is faster than using the command-line interface in scripts, because multiple command can be executed on a single connection, and because it returns Helix server responses as Ruby hashes and arrays.

For P4Ruby requirements see "Compatibility Statements" in RELNOTES
