Stuck at "No Elm projects found" & "Attach elm.json (or elm-packages.json)"

Under Windows 10 1903, with PhpStorm 2019.2.3, my editor keeps saying “No Elm projects found” & “Attach elm.json (or elm-packages.json)”

When I “attach” an elm.json, I’m getting the error: org.elm.workspace.ProjectLoadException: Could not find file C:\Users\hjpol\AppData\Roaming\elm\0.19.0\package\elm\browser\1.0.1\elm.json. Is the package installed?

Well, there is no C:\Users\hjpol\AppData\Roaming\elm\ on my system, so that’s true.

The plugin (under settings) can find the the elm compiler, and elm-format.

I do have elm installed:

>elm
Hi, thank you for trying out Elm 0.19.1. I hope you like it!

@HenkPoley the issue described in your most-recent comment will be fixed by #688 . I now install the dependencies automatically by copying the elm.json file into a temporary directory along with a dummy .elm file and compiling it.

This will fix the case where users simply have not ever downloaded the dependencies, as well as the case that you mentioned where the elm-stuff directory has the dependencies cached, but the dependencies are not actually installed in Elm’s global package cache.

[HenkPoley]

Solution:

• All your .elm source files need to be in src/, or well… the directories that are pointed at in elm.json: { "source-directories": [ "src" ] }.
• You need to have run elm make or elm reactor (this was important on a colleague’s machine that I tested as a ‘clean slate’)

Maybe make this more explicit?

• Say that the currently opened .elm file is not in any of the source-directories mentioned in elm.json.
• Tell the user which directories are in the list
• Offer to add the directory to the elm.json
• Offer to run elm make to download the libraries

Tangentially related:

I’ll also patch https://github.com/henkPoley/laravel-elm/tree/patch-1/ to drop the example .elm file in src/. composer install tightenco/laravel-elm:dev-patch-1 with this added to composer.json first:

    "repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/HenkPoley/laravel-elm"
    }

Edit: maybe I’ll need to figure out the best place to drop this file, since the elm compiler will complain if it’s in src/Example/Main.elm, and not src/Main.elm.
