Hide Unformatted TypeScript errors / move to after the pretty errors

[robertmoura]

Really loving the format of these errors! It's a lot easier to read.

The only thing I noticed is that the unformatted errors are still showing up. Was this intended or is there a way to remove them?

Update / TLDR

This is currently intentional but there are plans to improve the experience. This could potentially be improved by:

• Removing the original error
• Changing the order of the errors so that the pretty version is on top

The issue is that the improvements rely on changes to VS Code. Go upvote this issue if you want these changes!

3. VSCode markdown blocks all styling options, so I had to find hacks to style the error messages. e.g., there isn't an inlined code block on VSCode markdown, so I used a code block inside a codicon icon, which is the only thing that can be inlined. That's why it can't be copied. but it isn't a problem because you can still hover on the error and copy things from the original error pane.

Hmm. Well, if it's possible, having an option to disable them is much preferred than having a bunch of similar errors in a scrollable small container. For the copy-pasting issue, I believe the error translation feature and also the built-in Problems panel should be enough, since it shows the raw version of the error.

[robertmoura]

I agree! Would be great to have an option to disable them. Personally I never copy these errors anyway.

[Samathingamajig]

at most, i copy the error number, in this case ts(6196) or just 6196 and type ts in the search bar

@robertmoura Thank you for opening this issue 💁🏼‍♀️
As @Samathingamajig said, it is intended, but I planned to add an option to choose whether you want to see TypeScript original errors after I'll succeed in making the types copyable.
Unfortunately, I failed to find a hack due to the strict limitations there:
https://github.com/microsoft/vscode/blob/b0d7acec38cfab4d82630cba64d581bf1cd1a305/src/vs/base/browser/markdownRenderer.ts#L372

So, I'll explore adding a setting that will hide TypeScript's original errors very soon.
Until then, if someone want to open a PR for that, you're more than welcome 🙂

Are extensions able to silence the errors of another extension?

@Samathingamajig Actually I didn't find any API of VSCode that allows that.
Does someone have an idea how we can remove the original TypeScript diagnostics?

Maybe we should address it with a language service plugin like this guy did here?
@johnsoncodehk @Samathingamajig @tjx666
WDYT?

Personally, I don't think it's worth it to try to silence the original error. Since formatting restricts the ability to copy/paste the error with the customize one, you get the benefit of being able to easily copy the raw error without going to the error panel. I would imagine silencing the error with a language service plugin would also remove the error from the error panel, as well as hiding it from your extension (unless your extension relies on a separate language server, which I doubt).

At least it would be cool to have the pretty error first in the tooltip 🤞

[yoavbls]

It was the first on the tooltip a while ago, I'm not sure why it changed.
@johnsoncodehk has some breakthroughs there by moving the error-providing mechanism to the language service plugin.
It'll allow us to control the order and hide the original errors.

We'll update about it soon 🙏🏼

[johnsoncodehk]

Just to clarify...don't expect it, the language server can cut the original error message, but this will also cause extensions like ErrorLens that rely on diagnostic messages to not work, so I don't think that's the way forward. Still need see VSCode how to improve.

In addition, the language server can only control the order of hover messages, but cannot make the hover messages displayed on top of the diagnosis.

Sorry for the false hopes.
