How To Install python3-antlr3 on Ubuntu 20.04
Introduction
In this tutorial we learn how to install python3-antlr3 on Ubuntu 20.04.
What is python3-antlr3
python3-antlr3 is:
ANTLR, ANother Tool for Language Recognition, (formerly PCCTS) is a language tool that provides a framework for constructing recognizers, compilers, and translators from grammatical descriptions containing C++ or Java actions (You can use PCCTS 1.xx to generate C-based parsers).
Computer language translation has become a common task. While compilers and tools for traditional computer languages (such as C or Java) are still being built, their number is dwarfed by the thousands of mini-languages for which recognizers and translators are being developed. Programmers construct translators for database formats, graphical data files (e.g., PostScript, AutoCAD), text processing files (e.g., HTML, SGML). ANTLR is designed to handle all of your translation tasks.
Note that this package contains patches for OpenStack Congress.
