ES6 Imports Sorter

Experimental ES6 import order sorter. Built as a way to understand the Elm Parser.

Warning: This script over-writes files.

To run

# install elm globally so you can compile the
$ brew install elm # or `npm i -g elm`
$ make 

# now just run the index.js file in node
$ node index.js --file <file_path>

$ node index.js --help # show help/usage information.

Custom sort order

$ node index.js --file <file_path> --sort defaults,objects,none,asterix

Sort order meaning:

Available options:

- defaults // import Default from "somewhere"; OR import Default, { AndThatThing } from "somewhere";
- objects // import { theThing, orOtherThing } from "somewhere";
- none // import "globally.css";
- asterix // import * as something from "somewhere";

Note: If you want to specify a custom order (using the --sort option), you have to mention all four options in the order you want.

These are the only valid import strings this tool can parse:

import Something from "somewhere";
import SomethingToo, { anotherThing } from "elsewhere";
import { theThing, OrThatThing } from "../../wherever.js";
import "../whatever.css";
import * as sayWhat from "everywhere";
import { 
  A,
  B,
  C,
} from "D";

Dry-run

Don't want the script to "fix"/overwrite files? Use the --dry-run flag.

node index.js --file /some/file.js --sort "defaults,asterix,objects,none" --dry-run

This will output the final "fixed" content to the console.

Note: Because Parser.deadEndsToString is a TODO at this time, the script uses Debug.toString and therefore compiles only in DEV mode.
