Escodegen (escodegen) is an ECMAScript (also popularly known as JavaScript) code generator from Mozilla's Parser API AST. See the online generator for a demo. This repository contains the Python translation of Escodegen.

Install

pip install escodegen

Usage

Example:

import escodegen

escodegen.generate({
    'type': 'BinaryExpression',
    'operator': '+',
    'left': { 'type': 'Literal', 'value': 20 },
    'right': { 'type': 'Literal', 'value': 2 }
})

produces the string: '20 + 2'

Example:

import escodegen
import esprima

escodegen.generate(esprima.parse('let a=10;let b=20'))

produces the string: 'let a = 10;\nlet b = 20;'
