CSS syntax suddenly produces lots of errors

[Tony Mechelynck]

Suddenly when opening a CSS file in Vim (or when opening an HTML file,
because HTML syntax invokes CSS syntax), I see a huge lot of errors.
This is at patchlevel 9.1.296 or earlier. I didn't see it a few days
ago but I'm not sure at which changeset it appeared.

I'm copying below what I saw while opening one HTLM file :

"pub/public/nb_au/nbau.contents.html"

Have same version, no issues opening html file with embedded css.

[Christian Brabandt]

Hm, may it be related to my patch: https://github.com/vim/vim/pull/14433

It also seems to break on FreeBSD and MacOS CI, so I am planning to back
it out later today.

Can you please check v9.1.295? And can you also check if `:set re=1` helps?

If this is indeed that patch causing the issue, can you please share the
html file?

Thanks,
Christian

i am using v9.1.296, did not see this error.
however, 'cssMathParens' seems truly not existed?
// perhaps not related your patch, but syntax wrong.

I did `:set re=1` and got same error

[Maxim Kim]

Tried the same in v9.1.0295 -- works both with `:set re=1` and `:set re=0`

You only get the error with :set re=1? But :set re=2 works?
Hm...

Thanks,
Christian

Yow! Those people look exactly like Donnie and Marie Osmond!!

I have just tried `:set re=2` -- works too

[Maxim Kim]

oh 2 was probably auto selected for me when 0 was set :)

I can’t reproduce this when opening a CSS file in Vim 9.1.350 with `syntax on`

Do you have any plugins installed? Can you try reproducing with `vim -u NONE` to load without any config?

it was an issue at 9.1.296 which Tony reported, but later it backout at 9.1.297; but i did not face same issue even it was 9.1.296;
regardless this issue, my rough thinking at that time was 'cssMathParens' was missing definition, but i maybe wrong too;
so if you checked now there is no issue, then it should be ok now, sorry if bother.
