fancy-regex VS sd

https://github.com/fancy-regex/fancy-regex/issues/84 it's still open issue

Ahh, very interesting, thanks for sharing! Do you have any thoughts around why that is? I presume that's due to Oniguruma supporting a much broader feature set and something like fancy-regexp's approach with mixing a backtracking VM and NFA implementation for simple queries would be needed for better perf? (I am aware you played a role in that) [1]

I have been playing around with regex parsing through building parsers through parser combinators at runtime recently, no clue how it will perform in practice yet (structuring parser generators at runtime is challenging in general in low-level languages) but maybe that could pan out and lead to an interesting way to support broader sets of regex syntaxes like POSIX in a relatively straightforward and performant way.

Not an expert but fancy regex is a Rust library that uses a hybrid approach to detect whether a sub expression contains backtracking and delegates to the appropriate engine.

I wanted to like sd but it doesn't support my main use case of recursive search/replace. Imagine every time you wanted to grep some files you had to build a find+xargs+rg pipeline... it just takes me out of the flow too much. I'm glad people are posting other options here, I'm looking forward to trying them.

sd

https://github.com/chmln/sd ftw (sed rebuilt in rust, much easier imho) ;-)

sd is a more intuitive alternative to sed, focussing on making find and replace easier - which is all I ever used sed for.

If it's in multiple files? To be honest, I'd just use a terminal and sed (or sd if you want something with a more friendly interface).

I love the idea and I'll try it out, but a heads up in case the author is around: the name sd clashes with another tool [0], which works as an alternative to sed.

I use that one pretty often, so maybe my first managed script will be one which symlinks binaries :)

sd is a find-and-replace CLI, and you can use it as a replacement for sed and awk. It is way more user-friendly and modern. It is also magnitudes faster than sed.
