ripgrep
ripgrep recursively searches directories for a regex pattern while respecting your gitignore
Basic code searching skills seems like something new developers are never explicitly taught, but which is an absolutely crucial skill to build early on.
I guess the knowledge progression I would recommend would look something kind this:
- Learning about Ctrl+F, which works basically everywhere.
- Transitioning to ripgrep https://github.com/BurntSushi/ripgrep - I wouldn't even call this optional, it's truly an incredible and very discoverable tool. Requires keeping a terminal open, but that's a good thing for a newbie!
- Optional, but highly recommended: Learning one of the powerhouse command line editors. Teenage me recommended Emacs; current me recommends vanilla vim, purely because some flavor of it is installed almost everywhere. This is so that you can grep around and edit in the same window.
- In the same vein, moving back from ripgrep and learning about good old fashioned grep, with a few flags rg uses by default: `grep -r` for recursive search, `grep -ri` for case insensitive recursive search, and `grep -ril` for case insensitive recursive "just show me which files this string is found in" search. Some others too, season to taste.
- Finally hitting the wall with what ripgrep can do for you and switching to an actual indexed, dedicated code search tool.

Maybe some other PCRE-compatible implementation offers streaming. For instance, https://www.intel.com/content/www/us/en/developer/articles/t... says it has this feature, but of course given who it's from it may be tied to a single brand of CPU.
github seems to be https://github.com/intel/hyperscan

regex
An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.
The homepage has a benchmark that compares Zed's "insertion latency" to other editors, and this is the description:
> Open input.rs at the end of line 21 in rust-lang/regex. Type z 10 times, measure how long it takes for each z to display since hitting the z key.
Could someone clarify what that means? My interpretation of that was to go to https://github.com/rust-lang/regex/blob/master/regex-cli/arg... and start typing 'z' at the end of line 21, but that doesn't seem to make any sense. I guess that repo got refactored and those instructions are out of date?

micromatch
Highly optimized wildcard and glob matching library. Faster, drop-in replacement to minimatch and multimatch. Used by square, webpack, babel core, yarn, jest, ract-native, taro, bulma, browser-sync, stylelint, nyc, ava, and many others! Follow micromatch's author: https://github.com/jonschlinkert
Packages on the RHS can contain wildcards, but must be escaped with brackets if so. We use micromatch for matching. Refer to their documentation for questions on matching behavior and available functionality.
