Classes and Missing space before function parentheses. (space-before-function-paren)

[yormi]

Ok, I'm not sure if it's the right place to post the issue but I haven't manage to determine if the problem lies in standard or eslint or babel-eslint... maybe you could help me !

Same problem than posted here(#59). I tried to test with Eslint using the rc/.eslintrc of this project but I'm still confuse with all that.

class foo {
    somefunction () {
    }
}

giving:
Missing space before function parentheses. (space-before-function-paren)

In package.json:

"standard": {"parser": "babel-eslint"}

I don't think setting the parser to babel-eslint is required anymore.

When I take the code above and paste it into http://standardjs.com/demo it comes back valid with no errors.

Could you try reinstalling the latest version of standard and testing again?

[yormi]

Everything is up-to-date. I reinstalled Standard just in case but no difference. Still the same error that indeed doesn't appear on the standardjs demo page.

For the parser, without it, I have weird stuff like an Parsing Error: Unexpected token function when I use that great async keyword.

Ah ha ! Just found the problem ! I'm using vim as well as the auto-format taken from the readme:
autocmd bufwritepost *.js silent !standard % --format
set autoread

It was actually removing the space between the function name and the () without refreshing the buffer. Got lucky to notice it.

I guess the problem would rely in the formatter then... and maybe some change to the vim autoformat command would help detect other potential future error ?

Does standard actually support ES6 features that are now part of the stable node.js build?

export class Foo {
  constructor (bar) {
    this.baz(bar)
  }
  baz (bar) {
    console.log(bar)
  }
  test () {
    console.log('test')
  }
}

Using this code snippet with standardjs.com/demo, "Format" button not giving a correct result:

export class Foo {
  constructor( bar) {
    this.baz(bar)
  }
  baz( bar) {
    console.log(bar)
  }
  test() {
    console.log('test')
  }
}

Of course after code was formatted, linter reports errors. Thats an incorrect behaviour.

Same story with the object shorthand:

let test = {
  foo () {
    console.log('foo')
  }
}

test.foo()

After format, becomes the

let test = {
  foo() {
    console.log('foo')
  }
}

test.foo()

Generating new "Missing space before function parentheses" error.

+1 same problem as @yura415: the formater messes up the parentheses spacing.

[pnw]

+1 getting the same thing. The formatter breaks the subsequent lint.

Yeah, the formatter has issues with some ES6 features. You can help fix these issues by contributing to the standard-format project! It will get better with time.

This issue is already open on that issue tracker: maxogden/standard-format#134
