RIDL Compiler¶ ↑

RIDL is a Ruby library implementing an Object Management Group (OMG) IDL parser/compiler frontend with support for pluggable (and stackable) backends created by Remedy IT.

RIDL provides a framework for implementing compiler/generators for OMG standard IDL definitions. The framework includes:

• a RACC based parser supplemented with a custom scanner/tokenizer

• a complete AST class hierarchy for representing parsed IDL specifications

• a complete Type class hierarchy

• IDL constants expression support

• a builtin IDL preprocessor expression parser/evaluator

• a flexible framework for pluggable (and stackable) backends

• basic support for backend code re-generation

• compliant with the OMG IDL 3.5 standard

• support for OMG IDL 4.2 annotations

• experimental support for IDL 4.2 map, int8/uint8, explicitly-named integer types, bitmask, bitset, empty struct, and struct inheritance

Remedy IT has developed multiple backends for RIDL. These include the following open source backends:

• R2CORBA generating Ruby code

• TAOX11 generating C++11 code

• AXCIOMA generating C++11 code

If you find a bug, please report it as RIDL issue.

RIDL is distributed as a Ruby Gem. You can download and install RIDL as a Ruby Gem from the common Rubygems.org repository by executing the following command:

$ gem install ridl

The RIDL Gem is a Ruby-only Gem without any dependencies.

A new RIDL ruby gem release can be made by incrementing the RIDL version in lib/ridl/version.rb and create a new release on github matching the new version (for example v2.7.0). The github Ruby Gem Release action will automatically create a new gem and push it to Rubygems.org.

The file ‘lib/ridl/parser.rb` can be regenerated using `racc -o parser.rb -F -E parser.ry`. The option `-E` embeds the racc parser within RIDL which is required for RIDL because jruby doesn’t contain ‘RACC` as cruby does.
