Xo: Unexpected token t

[dawsbot]

async operations are suddenly failing that were previously not. Even my Travis builds are failing. Here is the line which fails (taken directly from del):

test('delete files - async', async t => {

To reproduce, I made my own coding an externality by downloading and running the tests for del.

$ git clone [email protected]:sindresorhus/del.git
$ npm install
$ npm test

  test.js:29:36
  ✖  29:36  Parsing error: Unexpected token t

  1 error

This is caused by https://github.com/eslint/eslint/issues/6158.
There is already an open PR to fix the issue: https://github.com/eslint/eslint/pull/6160

Pin eslint to 2.9 until that is resolved. You can do that in package.json. Here is the updated package.json that makes the del example work.

  "devDependencies": {
   ...
    "xo": {
      "version": "*",
      "dependencies" : {
        "eslint": "2.9.x"
      }
    }
  }

@sindresorhus - do we want to cut a quick release pinning the eslint version? I think the eslint regression will be fixed pretty quick, but we are breaking builds right now.

[sindresorhus]

Pinned in 0.15.1.

[kevva]

Should be fixed in 2.10.1.

[sindresorhus]

Yup, I'm just giving it some days before upgrading ESLint again, in case it there were other bugs.

This can be closed now, ESLint was _unpinned_ in https://github.com/sindresorhus/xo/commit/4ae7f091b1c1d35d405c8d2ad53d0806da4f24d2
