How To Install yascreen on CentOS 8

yascreen is Yet Another Screen Library (lib(n)curses alternative)

Introduction

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

What is yascreen

lib(n)curses alternative oriented towards modern terminals. Suitable for developing terminal applications or daemons with telnet access and terminal support. Main features * small footprint * does not have external dependencies * allows both internal and external event loop * allows stdin/stdout or external input/output (can work over socket) * supports basic set of telnet sequences, making it suitable for built-in terminal interfaces for daemons * supports a limited set of input keystroke sequences * fully Unicode compatible (parts of this depend on wcwidth in libc) * supports utf8 verification of input * relies only on a limited subset of ANSI/xterm ESC sequences, making it compatible with mostly all modern terminals (inspired by linenoise) * there is no curses API and ancient terminal compatibility, hence less bloat * clean API with opaque private data, usable from C/C++
