Fix #389: Allow secondary alphabetical sorting by randallreedjr · Pull Request #629 · import-js/eslint-plugin-import

randallreedjr · 2016-10-17T22:25:44Z

After sorting imports by group, allow sorting alphabetically within a group
import/order rule now accepts sort-order option that may be 'ignore' (default) or 'alphabetical'
Fixes [import/order] sort order within groups #389

randallreedjr · 2016-10-17T22:26:32Z

This is my first attempt at trying to implement a secondary alphabetical sort on imports. I would appreciate any feedback!

I resolved the test coverage decrease. Not sure why appveyor is failing, but it appears to be happening when trying to run coveralls.

Hey @randallreedjr! Thanks a lot for working on this.

This is a pretty good start, but I have quite a few request changes. Let me know if you disagree, need explanations or guidance :)

jfmengels · 2016-10-18T21:26:39Z

 import sibling from './foo';
 ```

+### `sort-order: [ignore|alphabetical]`:


Bikeshedding: maybe simply call this sort?

jfmengels · 2016-10-18T21:39:28Z

      },
      'Program:exit': function reportAndReset() {
        makeOutOfOrderReport(context, imported)
+        makeOutOfAlphabeticalOrderReport(context, imported, sortOrder)


Wrap this in a if (sortOrder === 'alphabetical') {} and remove the latter comparison to ignore. This will make it clearer when this will be called, and comparing it to 'alphabetical' will prevent surprises when we add other sort cases later on. Also, you won't have to pass this parameter around.

Another separate thing:
I think it would be nice to to not re-report the modules that were reported in makeOutOfOrderReport.

Let's assume lowercase to be part of group 1, uppercase of group 2, and group 1 should appear before group 2.

import 'B'; import 'A'; import 'b'; import 'a';

I haven't tried it yet, but I wouldn't be surprised if there were two error reports for moving B to a latter location or something. I would love some tests on that too, though the problem might not be shown with this example.

The reason I'm worried about this, is when you introduce the order rule to a new codebase, where imports are sorted in random ways, you'll get a lot of errors for the import section. I'd like for it to be the least confusing people and avoid having 20 errors when you required 10 modules. Note that the code might actually do this already, but without tests I have trouble being sure.

By not re-reporting modules, I think findOutOfAlphabeticalOrder could be simplified a bit too. I'm a bit confused about its inner workings at the moment.

Also, with only the makeOutOfOrderReport report, you have a consistent should occur before/should occur after message. I think it would be nice if that was true for all of the reports. Maybe compile the whole list with the group and the sort options one way, then do it the other way and take the shorter one.

Sorry to add a lot of work 😅

jfmengels · 2016-10-18T21:40:53Z


+function makeOutOfAlphabeticalOrderReport(context, imported, sortOrder) {
+  const outOfOrder = findOutOfAlphabeticalOrder(imported, sortOrder, 'a-z')
+  if (!outOfOrder.length) {


if (outOfOrder.length === 0) {}

jfmengels · 2016-10-18T21:43:07Z

+    reportOutOfAlphabeticalOrder(context, reversedImported, reversedOrder, 'after', 'z-a')
+    return
+  }
+  reportOutOfAlphabeticalOrder(context, imported, outOfOrder, 'before', 'a-z')


Is there maybe a way to refactor this function and makeOutOfOrderReport, they are really similar. Forget it if you deem that it then becomes harder to read.

jfmengels · 2016-10-18T21:47:00Z

+    return firstName > secondName
+  } else {
+    throw new Error('Invalid alphabetical direction' + direction)
+  }


function alphabetical(firstName, secondName, direction) { if (direction === 'a-z') { return firstName < secondName } return firstName > secondName }

You won't ever enter the last case, so no need to account for it.

jfmengels · 2016-10-18T22:07:08Z


+function alphabetical(firstName, secondName, direction) {
+  if (direction === 'a-z') {
+    return firstName < secondName


The same module could be imported twice, so this should be <= and >=. Please add a test for that case :)

jfmengels · 2016-10-18T22:07:44Z

  }).reverse()
 }

+function alphabetical(firstName, secondName, direction) {


Name it something like compareAlphabetically? Or isBeforeAlphabetically (berk). They're ugly names, so if you have better ideas, go for it, but at the moment, without looking at the code and by just looking at places where it's called, it's hard to know what exactly this function does.

isAlphabetized?

jfmengels · 2016-10-18T22:16:47Z

+      direction
+    )
+    const reversedDirection = direction.split('').reverse().join('')
+    if (alphabetical(importedModule.name, maxSeenAlphabeticalNode.name, reversedDirection)) {


Unless the two names are the same, isn't this just equal to resAlphabetical?

snoob · 2018-06-28T23:12:48Z

@ljharb too late :p i have already rebased the @randallreedjr on my repo branch https://github.com/snoob/eslint-plugin-import/tree/import-sort-order you can pull them :) i changed my mind i ll be more reactive if this PR is synchronized to my repo

janpaul123 · 2018-07-10T22:24:35Z

This PR adds an optional configuration that a lot of people want. I don't quite understand the controversy?

ljharb · 2018-07-10T22:27:56Z

@janpaul123 there's no controversy; it's just that the number of people that want an option is irrelevant if that option can't be provided correctly.

ljharb

To reiterate, the changes requested here are still needed for this to go in.

ljharb · 2018-07-10T22:32:23Z

@snoob thanks for the help, i've used your rebase to update this PR.

janpaul123 · 2018-07-12T17:32:09Z

@ljharb cool, makes sense. I think it is good to fix problems with this rule before adding more functionality to it, thanks for reiterating that. 👍

I unfortunately really needed this functionality though, and also the autofixing (which this PR doesn't include), so for anyone who comes across this thread and needs that too, I made a small package based on another PR over here: https://github.com/janpaul123/eslint-plugin-import-order-alphabetical It's not perfect but it suited my needs well enough. 🤷‍♂️

snoob · 2018-07-13T07:31:03Z

@ljharb : What do you think about @janpaul123 work ?

Because we have to fix test on this branch and we don't have autofix also
So what do we do ? Do we provide a native solution on this repo ? or we assume that you need an additional plugin for alphabetical sorting ?

ljharb · 2018-07-16T06:11:22Z

@snoob any time you have commits you want me to pull into this PR, please ping me here and I'll do so.

itajaja · 2019-02-13T19:52:31Z

hi @ljharb, I'll be happy to pick up the torch from where it was left. by following the conversation, it seems like the main problem is interleaved code between import groups, but as far as I can tell, that seems resolved. is it something in here specifically that adds a regression? happy to open a new PR for the additional work, or for you to cherry pick from my branch.

ljharb · 2019-02-23T00:27:58Z

@itajaja posting a link here would be preferable to opening a new PR; indeed, if the interleaving concerns mentioned upthread are covered by tests, this PR, rebased, might be sufficient.

It's a bit tricky right now, though, because tests are failing on master.

jeffshaver · 2019-03-11T01:29:05Z

@ljharb also interested in this. let me know if any help is needed getting this done

VincentLanglet · 2019-04-19T14:26:51Z

Just to be sure, this only sorts based on path of import NOT on variable being imported.. So import { prop }..., import Abc..., import *... , etc will have no effect.
