Suppressing Errors in `.gts` files?

[gossi]

In my attempt to add glint support for ember-truth-helpers, see jmurphyau/ember-truth-helpers#176 the tests bombard the helpers with all sorts of data types. For example:

I tried to suppress them with @glint-ignore (which I found is only for use within <template>), then I tried @ts-ignore and @ts-expect-error but neither of them causes glint to silence over these expected errors.

I even got this response from glint: Unused '@ts-expect-error' directive. glint(2578) (from eslint extension in vscode - I guess?).

So, I was wondering if this is missing or if I couldn't figure this out?

The comment needs to be within the template. I can't copy and paste your example since it's an inaccessible screenshot, but for instance:

await render(<template>
  {{! @glint-expect-error }}
  {{eq "hello" 123}}
</template>);

Oh sorry, my bad. The screenshot is there to show the squiggly lines.

It is actually the code above:

    const fakeContextObject = EmberObject.create({
      valueA: null,
      valueB: null,
    });

    const contextChild = fakeContextObject;

So, within a gts file, there is no way to suppress error message in the ts/js part. I tried known ts directives, such as: @ts-ignore - but glint doesn't know about them.

@ts- directives should work as normal in .gts files:

I pulled the branch you linked and looked at the file in question and can confirm that @ts-ignore silences the error in the EmberObject.create call, so I'm going to close this out.

If you're able to put together an isolated reproduction I'm happy to reopen and take a look
