Structure

This extension is written in TypeScript, was developed with Node 16 and has two main parts: the client and the server. Inside server/src yo can find all the code related to the server side. All the code for the client side is located at client/src.

The code parser is generated with ANTLR4 using the latest version of the EO grammar.

Publishing the extension is done with Rultor (see .rultor.yml).
