MoLang parser for Javascript

Installation

npm install molangjs -s

Usage

Parser

To calculate the result of a MoLang expression, use Molang#parse()

const MolangParser = new Molang();
MolangParser.parse(expression, variables);
  • [string] expression: MoLang expression.
  • [object] variables: (Optional) Object of variables to pass to the parser. Each variable can be a number or another expression.

Options

  • [object] Molang#global_variables: Object of global variables. If no matching variable is passed along, these variables will be used.
  • [boolean] Molang#cache_enabled: Whether to use caching to make the processing of expressions faster. Default: true.
  • [boolean] Molang#use_radians: Use radians instead of degrees for rotations in trigonometric functions. Default: false.
  • [function] Molang#variableHandler: Custom handler for unrecognized variables. Default: undefined.

Example

import Molang from 'molangjs';

const MolangParser = new Molang();

let result = MolangParser.parse('query.has_rider ? Math.sin(query.anim_time) : -44 * 3', {
    'query.has_rider': 1,
    'query.anim_time': '11 + 5'
});
