LGTM1 to ship with a killswitch flag, just in case. Thanks for the thorough analysis! On Thu, Apr 20, 2023 at 3:41 PM Mathias Bynens wrote: > I’ve continued analyzing UKM results and have now reached n=40 as Rick > suggested: > > | origin | link to analysis > |

I’ve continued analyzing UKM results and have now reached n=40 as Rick suggested: | origin | link to analysis | continues to work with the change? | | :--- | : | :- | |

Re: [blink-dev] Intent to Implement and Ship: Use RegExp v flag instead of u for HTML pattern attribute

I will say personally, as an author, I am generally accustomed to using special characters in my regex character classes freely, and hearing that the HTML spec is making a backwards incompatible breaking change that would prevent me from doing so is kind of surprising, and personally i would pr

Re: [blink-dev] Intent to Implement and Ship: Use RegExp v flag instead of u for HTML pattern attribute

I wonder if we can get enough confidence with less work than investigating 40 randomly chosen sites from UseCounter hits. This is a population proportion problem, and https://sample-size.net/confidence-interval-proportion/ is a useful tool. If you check 40 cases and find no breakage (N=40, x=0) th

Re: [blink-dev] Intent to Implement and Ship: Use RegExp v flag instead of u for HTML pattern attribute

Thanks for the guidance, Rick. I’ve prepared a CL moving the flag to status=experimental and I can commit to investigating 40 unique UseCounter hits and summarizing my findings. Fingers crossed the trend of “no actual breakage dete

Re: [blink-dev] Intent to Implement and Ship: Use RegExp v flag instead of u for HTML pattern attribute

Thanks for doing a thorough compat analysis of this Mathias. I can totally see this being one where all the examples we can find don't seem to cause breakage in practice. I know it's a lot, but if we looked at 40 random examples and found none of them to break, that would suggest an upper bound of

Re: [blink-dev] Intent to Implement and Ship: Use RegExp v flag instead of u for HTML pattern attribute

So far, none of the UseCounter hits I investigated constitute any actual breakage. The vast majority of hits seem to be login forms backed by server-side validation. I’ll keep looking though. In the meantime, this feature is now

Re: [blink-dev] Intent to Implement and Ship: Use RegExp v flag instead of u for HTML pattern attribute

I took a look at https://github.com/whatwg/html/pull/7908 and it looks like there's agreement to merge it, but it's waiting on this intent to be approved. Normally we block in the other direction, but that's fine, as long as the spec change is merged. Looks like there's broad support for this chan
