esformatter-var-each Build status

Esformatter plugin that converts comma var statements into separate var statements

This was created to make obfuscated scripts more palatable. However, it should be a nice addition to your web development tasks.

Features:

  • Preserves last character of var's (e.g. var a, b; -> var a; var b;)
  • Maintain indentation level of var's

Getting Started

Install the module with: npm install esformatter-var-each

Then, register it as a plugin and format your JS:

// Load and register our plugin
var esformatter = require('esformatter');
var esformatterVarEach = require('esformatter-var-each');
esformatter.register(esformatterVarEach);

// Format our code
esformatter.format([
  'var a = \'hello\',',
  '    b = \'world\';'
].join('\n'));
// var a = 'hello';
// var b = 'world';

Alternatively, load it via format directly:

var esformatter = require('esformatter');
esformatter.format([
  'var a = \'hello\',',
  '    b = \'world\';'
].join('\n'), {
  plugins: [
    'esformatter-var-each'
  ]
});

Documentation

esformatter-var-each exposes exports.transform for consumption by esformatter.

esformatterVarEach.transform(ast)

Walk AST and splice in var statements.

Warning: This mutates nodes in place

  • ast AbstractSyntaxTree - Abstract syntax tree provided by esformatter
