Ale: Issues getting Flow feedback

[alexlafroscia]

Problem

I'm unable to get Flow feedback from ALE. It was working a week or so ago, but trying it again today, I'm not getting the feedback. I've had the same problem on two different computers; I thought the issue was with my desktop, but my laptop isn't getting Flow details anymore either.

ESLint errors for the same file are reported fine.

File

// @flow





import add from './add';
import { Person } from './class';

const me: Person = new Person('alex');
me.setAge(add(10, 12));

add(4, 'foo');

console.log(me.name);

Screenshot

Here, I would expect the line adding a number and string to be marked as an error.

Flow Output

src/index.js:13
 13: add(4, 'foo');
            ^^^^^ string. This type is incompatible with the expected param type of
  3: export default function add(a: number, b: number): number {
                                               ^^^^^^ number. See: src/add.js:3

Yep, seems like breaking in this commit https://github.com/w0rp/ale/commit/0f0d1709c5b91a52b6d383762b5f47f20263d141

Could you set let g:ale_history_log_output = 1 and paste the output of :ALEInfo again? Also, if you have a project I could test this with, that would be helpful.

NeoVim splits lines above a certain size up in a very weird way that causes many issues.

[w0rp]

I should have fixed this now. Try again. The lines were being joined together, but the very last line needed to be added on when the job ended.

[alexlafroscia]

Yup, all fixed! Thanks so much @w0rp -- Ale has quickly become my favorite Vim plugin. Excellent work here.
