Text editors represent one of the fundamental tools that writers use – software developers, book authors, mathematicians. A text editor must work as intended in that it allows the users to do their job. We will start by introducing a small subset of a full-blown text editor – line editor. Next, we will give a concrete definition (specification) of what a complete text editor means. Afterward, we will provide an implementation of a line editor in Coq, and then we will prove that it is a complete text editor.
