PHP IDE :: NuSphere Forums :: View topic - False error in css when calc uses negative number

Posted: Tue Jun 13, 2023 5:16 am

When a calc expression uses a negative number the false parsing erro "unexpected "-"" is produced on the - symbol:

Code:

bottom:calc(var(--raggio) * -1);

This is present in the latest 20034 build

Thanks. Will check this.
Looks like -1 case is not defined in calc() syntax in css-values-3 https://www.w3.org/TR/css-values-3/#calc-syntax

I think it is defined, in product it uses a calc-number-value

https://www.w3.org/TR/css-values-3/#typedef-calc-number-value

Which in turn could be a number-value

https://www.w3.org/TR/css-values-3/#number-value

Which clearly can have a sign.

Still present in 20035.

Any news on that bug?

Thanks!

first of all, it's not a bug. Different version of standard define it differently, original css3 didn't define it at all.
2nd -- my understanding is that the issue was resolved in ~ July, at least I don't see any syntax errors for bottom:calc(var(--raggio) * -1);

If I insert a space between - and 1, syntax error will be properly reported

My PHPEd tells me I'm on the latest version and I still see the bug:

margin-right:calc((var(--coldxwid) + 10px) * -1 );

Still produces an error on the minus that starts -1...

20035 is not the latest. Can you re-check with the latest?

Tested with 20036 and the bug is gone!

Thank you very much!
