## Appendix H Emacs Octave Support

The development of Octave code can greatly be facilitated using Emacs with Octave mode, a major mode for editing Octave files which can e.g. automatically indent the code, do some of the typing (with Abbrev mode) and show keywords, comments, strings, etc. in different faces (with Font-lock mode on devices that support it).

It is also possible to run Octave from within Emacs, either by directly entering commands at the prompt in a buffer in Inferior Octave mode, or by interacting with Octave from within a file with Octave code. This is useful in particular for debugging Octave code.

Finally, you can convince Octave to use the Emacs info reader for `help -i`.

All functionality is provided by the Emacs Lisp package EOS (for “Emacs Octave Support”). This chapter describes how to set up and use this package.

Please contact Kurt.Hornik@wu-wien.ac.at if you have any questions or suggestions on using EOS.
