Introduction

In this tutorial we learn how to install re2c on Kali Linux.

What is re2c

re2c is:

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.

Another distinctive feature is its flexible interface: instead of assuming a fixed program template, re2c lets the programmer write most of the interface code and adapt the generated lexer to any particular environment.

There are three methods to install re2c on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.

Install re2c Using apt-get
