Relic

Relic is a coding language made to compile implicit yet readable code to pure, modern JavaScript. Since Relic is just a compiler for JavaScript, it can handle and compile expressions of both languages.

This package is still under development, and is not recommended to be used in production. Some parts of JavaScript are still not supported.

Overview

Relic

MyTypes as '', 1, false, null, foo: \bar

for index, value in MyTypes
  _type = typeof value

  console.log `{_type} value at {index}`

JavaScript output

let MyTypes;

MyTypes = [
    '', 1, false, null, { foo: "bar" }
];

for (index in (_j = MyTypes)) {
    value = _j[index];

    _type = typeof value;

    console.log(`${_type} value at ${index}`);
}

Installation

With Node.js

# for local development...
npm install --save-dev relic-lang

# if you'd like to use 'els' command globally...
npm install -g relic-lang

Usage

Command Line Interface

# with `.rcconfig`
rc

# compile a file manually
rc -c path/to/file.els

# compile a directory
rc -c path/to/folder path/to/destination

On Node.js

import Relic from 'relic-lang'

// prints "hello('world!');"
console.log(
  Relic.compile("hello 'world!'").output
);

// ---------

// parse a Relic Object Notation file
import fs from 'fs'

var RON = fs
  .readFileSync('path/to/.ron', { encoding: 'utf-8' });

console.log(
  Relic.toJSON(RON)
)

(.rcconfig has the syntax of a .ron file)

Do not place newlines between properties, or the file will be treated as an array.

sourceDir: 'path/to/folder'
# or...
sourceRoot: 'path/to/root' # optional
files:
  'my-file.rc'
  'another-file.rc'

  # whether you want a source map to be generated
  sourceMaps: yes or no
  # whether to place the source map as a data URI 
  # or generate a '.js.map' file containing the map
  inlineMap: yes or no
  # the output directory for all scripts
  # use '@' for same directory
