Build your own grep

Project · challenge · 2024

Build your own grep is his C++ solution to CodeCrafters' grep challenge: a version of the grep search tool with a regular-expression engine written by hand rather than taken from a library. The challenge works through regex syntax a piece at a time: character classes, anchors, quantifiers, alternation and groups. It is built with CMake and vcpkg.
