Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- grex 1.0.0 - Generate regular expressions from user-provided test cases
- Generating regex pattern automatically

Regex generator
Sounds like you're looking for something like grex. Mind you, this does not save you from learning about regular expressions. It‘s more of a supporting tool.
- When you have a problem and solve it using RegEx, you end up with two problems

RegExr: Learn, Build and Test Regex
If I understood what you mean, then yes, I bout one https://regex.help/ (powered by https://github.com/pemistahl/grex doing the heavy lifting).
- grex is a library as well as a command-line utility that is meant to simplify the often complicated and tedious task of creating regular expressions. It does so by automatically generating a single regular expression from user-provided test cases.

regex 1.8.0 released (no-op escapes allowed, (?<name>re) syntax added)
I believe you're the second person to tell me they were confused by this, so there are probably several others confused but didn't say anything. I've added a warning to the top of regex-automata's README.

After years of work and discussion, `once_cell` has been merged into `std` and stabilized
For anyone following along at home, we're having a very helpful discussion about the implementation I posted in my sibling comment here: https://github.com/BurntSushi/regex-automata/issues/30

Pomsky 0.8 released: A powerful and modern regular expression language
My current technique only gets applied to alternations of simple literals. But the idea is generalizeable and I speculate that it is actually impactful to generalize it.

Rust: A Critical Retrospective
(I could use '_ => {}' instead of 'None' to save a few more.)
I do find the 'if let' variant to be a bit easier to read. It's optimizing for a particular and somewhat common case, so it does of course overlap with 'match'. But I don't find this particular overlap to be too bad. It's usually pretty clear when to use one vs the other.
But like I said, I could live without 'if let'. It is not a major quality of life enhancement to me. Neither will its impending extensions. i.e., 'if let pattern = foo && some_booolean_condition {'.

Memchr 2.4 now has an implementation of substring search on arbitrary bytes
(The work on regex-automata 0.2 has been underway for over a year now.](https://github.com/BurntSushi/regex-automata/tree/ag/work) There's a lot done, but still a lot more to go. Once that's done, regex proper should be pretty close to a thin layer that glues regex-syntax, regex-automata, memchr and aho-corasick together. I don't currently expect regex to grow any more dependencies than that. And as it is, aho-corasick and memchr are both optional dependencies. Right now, regex-syntax is the only required dependency, but regex-automata will be added to that list.
