Unity Ripgrep Search Tool

Helper class for making your own search tools along with a built-in transient Ripgrep search window.

uses the fantastic ripgrep to search your Unity code, assets, prefabs and scene files
handy search window with multithreaded dispatch and parsing of ripgrep search results
advanced Unity users (those who know scene/asset/prefab file internals and basic regex) can find pretty much anything fast
find references to anything by just searching the GUID
save commonly used searches
optionally add any paths you want searched for code/files that live outside of the Unity world

install ripgrep (make sure it's on your path for Windows and available from /usr/local/bin/rg for macOS)
Unity LTS release (not tested on anything that isn't an LTS because I'm not insane enough to use one)

cmd/ctrl + G opens the search window
type at least 3 letters and press enter
escape stops the search if it is active or closes the search window if it is complete
results will ping on click and open to the search result line in TextMate on double-click (if on macOS with TextMate installed)
