;-less.js // Make your JavaScript Code Semicolon-less

Rationale

$3

$3

- ;-less // line starts with unary - operator
- ;+less // line starts with unary + opeartor
- ;/less/ // line starts with regexp literal
- ;[less] // line starts with array initializer
- ;(less) // line starts with grouping operator, such as IIFE

NOTE: In real-world, only the last case is common.

Usage

$3

``sh
npm install -g semicolon-less
`

$3

Convert test.js to semicolon-less style
`sh
semicolon-less test.js
`

Convert all js files to semicolon-less and output to dest directory
`sh
semicolon-less --out=dest *.js
`

Support pipe
`sh
echo 'let x = 1' | babel | semicolon-less
`

Read source code form stdin
`sh
semicolon-less -
`

All semicolon-less can be replaced by the shortcut -less, for example, to show the help:
`sh
-less --help
`




$3


`js
var less = require('semicolon-less')

// source can be a string or buffer or stream which contains the source code
var source = require('fs').readFileSync('source.js')

// less() return transformed source
var semicolonlessSource = less(source)
`




$3


`js
var gulp = require('gulp')
var less = require('semicolon-less/gulpplugin')

gulp.src('*.js').pipe(less())
``

Bugs and limitations

Currently I'm using yyx990803/semi as underground implementation, and it doesn't support some ES6 syntax (eg. for-of, generators. See the skipped tests). We will solve it in the future.

I want to convert semicolon-less style back to semicolon-itis style

It's totally unnecessary and not the scope of this project. But if you really
want it due to some reasons (ie. your boss/team/IDEs/tools insist on semicolon-itis style), use yyx990803/semi.

In fact, most js code generators will add semicolons as ASI rules. So you could just
use uglifyjs to regenerate your codes.

I don't agree with you; semicolons are REQUIRED!

Ok;
You must use Issac's awesome semicolons package;
> Ensure that all JavaScript programs have the maximum amount of safety;
> when you require("semicolons"), THEY ARE REQUIRED;
