Introduction

In this tutorial we learn how to install cl-trivial-gray-streams on Ubuntu 20.04.

What is cl-trivial-gray-streams

cl-trivial-gray-streams is:

This system provides an extremely thin compatibility layer for Common Lisp gray streams, which provide a standard way for users to define their own streams for use by the standard I/O functions.

Gray streams is an interface proposed for inclusion with ANSI Common Lisp by David N. Gray. The proposal did not make it into the standard, but most popular Common Lisp implementations implement this facility anyway.

This system provides an extremely thin compatibility layer for gray streams.

There are three methods to install cl-trivial-gray-streams on Ubuntu 20.04. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
