Superfluous triple-slash directives generated by Glint produce Glint errors (manually removing them fixes this)

[fry69]

In a fresh 5.6.0 install (ember new app --typescript) with just ember-concurrency 4.0.0 and most recent Glint (ember install ember-concurrency and following the basic instructions from https://typed-ember.gitbook.io/glint/environments/ember/installation), I get these errors when I run Glint on the terminal:

$ ./node_modules/.bin/glint

There are no preview types in ember-source for 5.6.0?

$ ls node_modules/ember-source/types
publish.mjs	stable

Looks like ember-page-title has had a similar issue with generated triple-slash directives, see ember-cli/ember-page-title#283

I can confirm that manually removing these generated /// lines fixes this issue for me.

@NullVoxPopuli can you confirm that applying the same solution/codefix from ember-cli/ember-page-title#283 would be the proper course of action here?

[NullVoxPopuli]

Can confirm.
These folks have used that solution so far: https://github.com/NullVoxPopuli/fix-bad-declaration-output/network/dependents

Gonna add it to the ts blueprint for v2 addons

Until the fix has landed and file in the node-modules directory tend to get replaced to their original state, here is a python script to remove those triple-slash lines.

import os
import re

dir_path = './node_modules/ember-concurrency/declarations/helpers'

for file_name in os.listdir(dir_path):
    if file_name.endswith('.d.ts'):
        file_path = os.path.join(dir_path, file_name)
        
        with open(file_path, 'r') as f:
            file_contents = f.read()
        
        file_contents = re.sub('^/// <reference types="[^"]+" />', '', file_contents, flags=re.MULTILINE)
        
        with open(file_path, 'w') as f:
            f.write(file_contents)

Was digging in to this yesterday, and it looks like the generated declarations may slightly be wrong? They're not using declare when exporting a const, and that breaks the ts parser used in fix-bad-declaration-output

[dfreeman]

Should we be using generated declarations at all? Last I knew ember-concurrency was still using a hand-rolled index.d.ts and the bulk of the actual implementation was still in JS, so I wonder if things were unintentionally switched over as part of the v2 migration.

Edit: ah, I was getting trolled by the start:types script not having the extra copy step cp src/index.d.ts declarations.d.ts step that the build:types script has.
