GNU TeXmacs

Abstract

GNU TeXmacs [vdH01, vdH02, Gro01] is a free software, which can both be used as a scientific text editor and as a front-end for computer algebra systems. The editor allows you to write structured documents via a wysiwyg (what-you-see-is-what-you-get) and user friendly interface. New styles may be created by the user. The program implements high-quality typesetting algorithms and TEX fonts, which allow the user to produce professionally looking documents.The high typesetting quality still goes through for automatically generated formulae, which makes TeXmacs suitable as an interface for computer algebra systems, or other types of "plugins". Currently, there are interfaces with Axiom, Giac, GNUplot, Graphviz, Gtybalt, Macaulay2, Maxima, Mupad, GNU Octave, Pari, Qcl, GNU R, Reduce, Scilab and Yacas. TeXmacs also supports the Guile/Scheme extension language, so that you may customize the interface and write your own extensions to the editor.In our demonstration, we plan to show briefly how to edit mathematical texts with TeXmacs, how to use computer algebra systems, and how to add interfaces with new systems in a very efficient way.
