strict mode syntax

[fibo]

@feross few days ago commented #287 (comment)

if for example I have a script like

#!/usr/bin/env node

const msg = 'Hello world'
console.log(msg)

node will complain something like

SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

but if I had "use strict" as you suggested, standard js will not accept it cause it is double quoted. I tryed with single quotes, but it does not work. Any hint?

What version of node are you using? I'm running v4.3.0 and your code example works fine without the need for 'use strict'.

[fibo]

Yes, sorry the error reported when requiring a file, here it is the complete code

script.js

#!/usr/bin/env node
"use strict"

let config = require('./config')

// just a check
console.log(config)

config.js

const fs = require('fs')
const mdconf = require('mdconf')
const path = require('path')

const readme = fs.readFileSync(path.join(__dirname, '..', 'README.md'), 'utf8')

let config = mdconf(readme).database.configuration

module.exports = config

You're missing 'use strict' in config.js. standard will not complain about a single quoted 'use strict' and that will work just fine.

Yes it works, thanks. I am glad anout that cause I am using standard js in a lot of my packages, thanks for creating it.

Let me report a working example

script.js

#!/usr/bin/env node
'use strict'

let config = require('./config')

// just a check
console.log(config)

config.js

'use strict'

const config = {foo: 1}

module.exports = config
