RE#: how we built the world's fastest regex engine in F#, https://iev.ee/blog/resharp-how-we-built-the-fastest-regex-in-fsharp/.

Excellent blog post!
Very interesting approach with new operations: intersection (&) and complement (~).

Implementation: https://github.com/ieviev/resharp-dotnet

My tip of the of the day.

To match a literal dot "." with a regular expression, write

"[.]"

instead of

"\\." or "\\\\." or even "\\\\\\\\.",

depending on context. 😀

Sharkey supports Regular Expressions for your hard and soft word mutes. Mastodon should too! If not raise holy hell with them.

The syntax for a case-insensitive #RegEx (#RegularExpression) for blocking "international airport" or "physical therapy" would be:

/.*international ?airport*./i
/.*physical ?therapy*./i

This would match:
- international airport
- International Airport
- InternationalAirport

And so on. Also, I'm purposefully not using any common triggers so as not to trigger any one.

Once you go regex in your word mutes you'll never want to go back to plain words ever again.

You don't need to use weird spellings or algospeak for any topics on the Fediverse ("unalived", "seggs" etc). There is no automated moderation or algorithm on here, moderation happens entirely through human beings and posts are shown in chronological order. In fact it's better that you use the correct spellings for difficult topics so that people with genuine traumas related to them can filter them more easily. #FediTips

How do I use regular expressions to mute specific terms without muting them if they're just part of a word?
So like, in a stupid example:
I want to block "lol" but not "testloltest"
