How to Install and Uninstall tcl-tclex on Ubuntu 22.04

Updated: October 30, 2022

tcLex is a lexer (lexical analyzer) generator extension to Tcl. It is inspired by Unix and GNU lex and flex, which are “tools for generating programs that perform pattern-matching on text”. tcLex is very similar to these programs, except it uses Tcl philosophy and syntax, whereas the others use their own syntax and are used in conjunction with the C language. People used to lex or flex should then feel familiar with tcLex. tcLex is a small extension (the Windows compiled version is about 20kb, and the source is about 150kb), because it extensively uses the Tcl library. However, the current doesn’t use Tcl’s regexp code anymore but a patched version is now included in tcLex, which makes it slightly bigger (by a few KB). tcLex should work with Tcl 8.0 and later. tcLex will NEVER work with earlier versions, because it uses Tcl 8.0’s “object” system for performance. The most interesting features are: I will show you how to install tcl-tclex on Ubuntu 22.04 in this tutorial.
