GReG stands for Git REpository Grepper, or Git Remote Entry Grepper if you prefer. It is a Golang tool to search for arbitrary strings in GitHub orgs/repos.
Other git hosting providers may be supported in the future.
Based on my experience of GitHub Enterprise at work, I often find GitHub indexing to be stale (potentially very much so) and to be highly particular about how it matches search terms against content.
To circumvent these limitations, gitfind queries GitHub repositories
(ensuring up-to-date content) and applies fast matching via the Aho-Corasick
algorithm.
The tool is written in Golang to provide a portable, lightweight executable.
