Ability to disable hint diagnostics request

[herberthamaral]

First of all: thanks for all the work done in this project! I (we) really appreciate it!

So I've been trying to disable a very annoying "error" for some months now: a hint diagnostic that both is visually distracting (because I can't do much about it) and misleading (since it adds up to the error count):

I try to read a bunch of code from flycheck, lsp-mode, pyright and finally decided to start opening some issues. Looks like lsp-mode asks pyright to send hint diagnostics, so I'm wondering if we could have a way to NOT send this kind of request, just in order to not have it displayed anywhere in the editor.

I am aware of flycheck error filtering, but it is not global: it is only meant to filter errors in the error list buffer.

Before looking for other solutions, have you tried prefixing unused args with _?

Hello! Just tried, doesn't work.

Did you want to simply disable that particular warning message from the type checker? If so have you tried adding:

# type: ignore 

to the line containing the warning - this should tell pyright to ignore that particular warning, this would also work if you were using mypy.

[herberthamaral]

Those are not type errors, so it doesn't ignore the diagnostic when I add # type: ignore.

@herberthamaral I tested with pyright and using _ for variable name fixes the issue.

I think the intention from the pyright team appears to be that it wasn't to be displayed as a diagnostic warning but a 'syntax highlight' indicating the variable is unused. I haven't checked any further on what supplemental information they may be supplying to indicate that distinction:
microsoft/pyright#1118
