How To Install perltidy on CentOS 8

perltidy is Tool for indenting and re-formatting Perl scripts

Introduction

In this tutorial we learn how to install perltidy on CentOS 8.

What is perltidy

Perltidy is a Perl script that indents and re-formats Perl scripts to make them easier to read. If you write Perl scripts, or spend much time reading them, you will probably find it useful. The formatting can be controlled with command line parameters. The default parameter settings approximately follow the suggestions in the Perl Style Guide. Perltidy can also output HTML of both POD and source code. Besides re-formatting scripts, Perltidy can be a great help in tracking down errors with missing or extra braces, parentheses, and square brackets because it is very good at localizing errors.
