## 4 Emacs tools ¶

Everyone writing code knows how important a good editor is. Most systems already come with Emacs, and excellent programmer’s editor. MDK adds support to Emacs for both writing and debugging MIX programs. A major mode for MIXAL source files eases edition of your code, while integration with Emacs’ debugging interface (GUD) lets you use `mixvm` without leaving your favourite text editor.

This chapter shows how to use the Elisp modules included in MDK, assuming that you have followed the installation instructions in See Emacs support.
