triggers-script

Top-level language to define events and main events behaviour.

Installation

npm i -s @allnulled/triggers-script

Importation

In node.js:

require("@allnulled/triggers-script");

In html:

<script src="node_modules/@allnulled/triggers-script/triggers-script.js"></script>

Once done this, you have available under window or global: TriggersScriptParser which is a typical pegjs parser.

Usage

require(__dirname + "/triggers-script.parser.js");

describe("TriggersScript Parser API Test", function() {
  
  it("can parse a simple event", async function() {
    TriggersScriptParser.parse(`
      on event {{ "wherever" }} as {{ "TR001" }} then {
        break process {{ p1 }}
      }
    `);
  });

  it("can parse all basic sentences", async function() {
    const js = TriggersScriptParser.parse(`
     // Comentarios válidos como en JavaScript
     // On event:
