RText - Ruby Textual Modelling

RText can be used to derive textual languages from an RGen metamodel with very little effort.

RText features include:

• Generic textual syntax

• Generic instantiator (parser) and serializer

• Consistency checks derived from the metamodel

• Designed to work with lightweight editor plugins providing

  • Syntax Highlighting

  • Auto Completion on language commands and model references

  • Error Annotations

  • Model Navigation

Installation

> gem install rtext

RText supports Ruby 2.6 to 4.0.

RText depends on the rgen and filelock gems, which are installed along with it.

Documentation

• RText_Users_Guide – the .rtext config file and the backend service

• RText_Protocol – the JSON protocol spoken between an editor frontend and a backend

• CHANGELOG – the changes in each release

Examples

test/integration/ecore_editor.rb is a complete backend service: it builds an RText::Language from the ECore metamodel, loads the model files it is given with RText::DefaultLoader, and serves them through RText::DefaultServiceProvider and RText::Service.
