Ways to Install or Uninstall re2c Ubuntu 22.04

Updated: September 16, 2022

re2c’s main goal is generating fast lexers: at least as fast as their reasonably optimized hand-coded counterparts. Instead of using a traditional table-driven approach, re2c encodes the generated finite state automata directly in the form of conditional jumps and comparisons. The resulting programs are faster and often smaller than their table-driven analogues, and they are much easier to debug and understand. Quite a few optimizations are applied in order to speed up and compress the generated code. In this tutorial, I will show you ways to install re2c Ubuntu 22.04.

Prerequisites

  • OS: re2c needs Ubuntu 22.04 to work
  • Privileges: Ascertain that you are able to execute sudo commands.
