irojs v0.1.5

This project aims to be a superset of Chris Ainsley's Iro, a development tool designed to simplify the creation of syntax highlighters.

Installation

npm install irojs

Usage

From the command line

Basic syntax:

iro compile <source> --targets=<targetlist>

Available targets:

• textmate or tm
  • textmate.xml (default)
  • textmate.json
• ace
  • ace.js (default)
  • ace.json
• ast — outputs the rion ast
• all or * — matches all targets
• none — only checks grammar

Use <target>.* to match all extensions.

Example:

iro compile mygrammar.iro --targets=textmate,ace -o out/

From code

Example:

import * as iro from "irojs";
// or
const iro = require("irojs");

const myGrammar = "...";

var result = iro.compile(myGrammar, { targets: ["textmate"] });

console.log(result.textmate);

Language Documentation

The documentation is still a WIP. In the meanwhile, you can access the original docs at https://web.archive.org/web/20191007073218/https://eeyo.io/iro/documentation/index.html

Development

pnpm build → builds the package.

pnpm build:swc → compiles the typescript source.

pnpm build:rion → compiles the rion grammar.

pnpm build:type → generates the type definition files.
