Respect EditorConfig settings #2760

josephfrazier · 2017-09-06T01:29:00Z

This is a simple way to address #42. It adds support for .editorconfig's indent_style, tab_width, and max_line_length properties.

I still need to add caching and a proper async implementation, but I think it's functionally correct. It doesn't support the end_of_line property as described in #42 (comment), but that could be added later.

We should test a more specific glob as well, with different settings, like [lib/**.js] (copied from http://editorconfig.org/).

See prettier#2760 (review)

josephfrazier · 2017-09-06T12:40:04Z

Good call, it looks like that exposed a bug as well. I still need to fix the pre-existing tests that now fail.

The tests were failing because they glob over all config-resolution test files.

eslint-disable comments shouldn't be needed because we ignore test_integration/cli/ in .eslintignore

There's no need for || result.tabWidth and || result.printWidth, is it? They are always goind to be undefined.

Couldn't we just do:

const editorConfig = editorconfig.parseSync(filePath); return { useTabs: ..., tabWidth: ..., printWidth: ... }

While being an odd configuration, isn't it valid to set indent_size, tab_width and max_line_length to 0, and as such we should respect that?

Yeah, that was also causing a bug. Not sure why I did it that way, but it's fixed in 54a5dcb

Good point, I'll try to fix that.

I'm still not 100% convinced we should add this, ~~as editors that use the prettier API (prettier-vscode, prettier-atom) will still have to implement it themselves.~~

edit: never mind, they get it from resolveConfig()

See prettier#2760 (comment)

Is it important that the .useTabs, .tabWidth and .printWidth properties of result are missing rather than present with the value undefined if the corresponding EditorConfig setting is missing?

Yes, I think that's what fixed this test: https://travis-ci.org/prettier/prettier/jobs/272596635#L379

While being an odd configuration, isn't it valid to set indent_size, tab_width and max_line_length to 0, and as such we should respect that? Note that 0 if a falsy value.

Hmm, it looks like tab_width and max_line_length must be positive. I suppose someone could set indent_size to 0, but I'm not sure if that edge case is worth supporting right now. At least, I haven't had time to put effort into it.

I guess it's all fine then 👍

lydell · 2017-09-11T18:16:03Z

@josephfrazier Is this still WIP or ready to merge?

josephfrazier · 2017-09-11T18:37:12Z

I haven't had time to add a proper async implementation, as well as caching. I think there might also be an bug in the case where there's no prettier config, but there is .editorconfig, but I'm not sure yet.

EDIT: I think this is ready now.

I like the implementation! Really easy to follow.

I left two small comments. Otherwise looks good to me.

Hmm ... this (and the change just above) are breaking changes – is that something we want to avoid?

This arrow function has no braces while the above when has.

What's the latest on this one?! (I don't mean to rush or anything.. just curious)

josephfrazier · 2017-10-30T20:51:30Z

@lipis, I'd still like to address @robwise's concerns in #2760 (comment), but I haven't had time to do so. While investigating that, I also noticed that resolve-config-editorconfig prioritizes indent_size over tab_width, which is exactly backwards according to http://editorconfig.org/:

tab_width: a whole number defining the number of columns used to represent a tab character. This defaults to the value of indent_size and doesn't usually need to be specified.

If you (or anyone else) would like to help out, please feel free to post patches (preferably wrapped in a <details> element) that I can test and add to the PR.

@robwise, I think your aforementioned concerns are now addressed. Would you mind taking another look and confirming?

After having to resolve merge conflicts with master yet again, I decided to go ahead and land this, especially since I believe all of the previously mentioned concerns have been adequately addressed.

azz · 2017-11-08T21:07:19Z

Not sure adding this in a hotfix is a good idea...

This reverts commit 8f58ca0.

lipis · 2017-11-08T21:22:36Z

Good stuff:)

josephfrazier · 2017-11-08T21:45:56Z

Oops @azz, I didn't realize that the next release was intended to be only a hotfix. What do you think about backing this out (#3213), releasing 1.8.2, then landing it again? It's been a rather long-running PR, so I'd really like to get it in.

As far as I can tell, the only projects this change could break are those that have .editorconfig properties without the corresponding .prettierrc options. Prettier would now take into account the extra .editorconfig properties, whereas before it wouldn't. This doesn't seem like such a big deal to me, considering that projects should edit/remove .editorconfig files that are intentionally disregarded when the code is checked in.
