How To Install libanyevent-perl on Ubuntu 20.04
Introduction
In this tutorial we learn how to install libanyevent-perl
on Ubuntu 20.04.
What is libanyevent-perl
libanyevent-perl is:
AnyEvent is not an event model itself, it only interfaces to whatever event model the main program happens to use, in a pragmatic way. For event models, the statement “there can only be one” is a bitter reality: In general, only one event loop can be active at the same time in a process. This module cannot change this, but it can hide the differences between them.
The goal of AnyEvent is to offer module authors the ability to do event programming (waiting for I/O or timer events) without subscribing to a religion, a way of living, and most importantly: without forcing your module users into the same thing by forcing them to use the same event model you use.
During the first call of any watcher-creation method, the module tries to detect the currently loaded event loop by probing whether one of the following modules is already loaded: EV, AnyEvent::Loop, Event, Glib, Tk, Event::Lib, Qt, POE. The first one found is used. If none are detected, the module tries to load the first four modules in the order given; but note that if EV is not available, the pure-perl AnyEvent::Loop should always work, so the other two are not normally tried.
