Ugrep – a more powerful, ultra fast, user-friendly, compatible grep

• ripgrep

  350 45,287 9.3 Rust

  ripgrep recursively searches directories for a regex pattern while respecting your gitignore

Another issue with Hyperscan is that if you enable HS_FLAG_UTF8[1], which hypergrep does[2,3], and then search invalid UTF-8, then the result is UB.

> This flag instructs Hyperscan to treat the pattern as a sequence of UTF-8 characters. The results of scanning invalid UTF-8 sequences with a Hyperscan library that has been compiled with one or more patterns using this flag are undefined.

That's another issue you'll need to grapple with if you use Hyperscan. PCRE2 used to have this issue[4], but they've since defined the semantics of searching invalid UTF-8 with Unicode mode enabled. ripgrep 14 uses that new mode, but I haven't updated that FAQ answer yet.

• rebar

  23 202 8.5 Python

  A biased barometer for gauging the relative speed of some regex engines on a curated set of tasks.

I'm the author of ripgrep and its regex engine.

Your claim is true to a first approximation. But greps are line oriented, and that means there are optimizations that can be done that are hard to do in a general regex library.

If you read my commentary in the ripgrep discussion above, you'll note that it isn't just about the benchmarks themselves being accurate, but the model they represent. Nevertheless, I linked the hypergrep benchmarks not because of Hyperscan, but because they were done by someone who isn't the author of either ripgrep or ugrep.

As for regex benchmarks, you'll want to check out rebar: https://github.com/BurntSushi/rebar

You can see my full thoughts around benchmark design and philosophy if you read the rebar documentation. Be warned though, you'll need some time.

There is a fork of ripgrep with Hyperscan support: https://sr.ht/~pierrenn/ripgrep/

I think you should try it before you read these benchmarks from the authors: https://github.com/Genivia/ugrep-benchmarks

• bat

  195 46,852 9.5 Rust

  A cat(1) clone with wings.

Good find, thanks! I'll check if I prefer it to moar.

As for bat, according to https://github.com/sharkdp/bat#using-bat-on-windows, the Chocolatey package simply installs `less` alongside `bat`. Seems like a good idea, but I haven't tried it.

• ired

  3 77 10.0 C

  minimalistic commandline hexadecimal editor similar to radare

So ired is a toy. One wonders how many search results you've missed over the years because of ired's feature "it's so minimal that it's wrong!" I mean sometimes tools have bugs. ripgrep has had bugs too. But this one has been in ired since 2009.

What is it that you said? YIKES. Yeah. Seems appropriate.

• moar

  6 554 9.5 Go

  Moar is a pager. It's designed to just do the right thing without any configuration.

I don't believe bat is a paper; it's more of a pretty-printer that tends to call less.

Two pallets that should work on Windows are https://github.com/walles/moar (golang) and https://github.com/markbt/streampager (Rust). There might also be a newer one that uses rust, I'm unsure.
