DeprecationWarning: Partial position information in the utils.report() function is deprecated ("prettier/prettier").

Looks like deprecated method is used:

Please pass both `index` and `endIndex` as arguments in the `utils.report()` function of "prettier/prettier".

Can you please provide an example of the misshapen code that you used to trigger this codepath?

I'm trying to recreate this locally.

@BPScott see the discussion upstream: stylelint/stylelint#8126

We found that providing only index can behave weirdly.

To improve the experience for end users we are moving away from position arguments that are ambiguous and could lead to bugs.

The deprecation warning is triggered by running with the latest version of stylelint and for example only providing index without endIndex.

Hopefully it isn't too disruptive to adapt to this new requirement.
Thank you in advance!

[BPScott]

Oh yeah it's no problem, I'm happy to add endIndex.

It's just my test fixture that I'm sure used to exercise this code path no longer seems to error in modern stylelint versions, so I'd like to find a case where this code path does get hit so I can test it. (I suspect that these days the invalid code is being caught somewhere in postcss-styled-syntax and so it never gets to running the prettier rule)

I trap on this when during running tests in @putout/processor-css before adding the flag, you can take a look at fixture files, as examples.

[romainmenke]

@coderaiser or you can provide a reproducible bug report? :)
I don't think anyone will take the time to dig through your project in search of samples that will trigger this code path 😛

[coderaiser]

Sure! As I remember, when I debug, I trapped on this input:

{{ template }}

Yes, that is not valid css, but when you put styles to style tag, and in runtime put the data from file, and then lint template it can be the case :)
