A Document-Oriented Coq Plugin for TeXmacs

This article discusses the integration of the authoring of a mathematical document with the formalisation of the mathematics contained in that document. To achieve this we have started the development of a Coq plugin for the TEXmacs scientific editor, called tmEgg. TEXmacs allows the wysiwyg editing of mathematical documents, much in the style of LATEX. Our plugin allows to integrate into a TEXmacs document mathematics formalised in the Coq proof assistant: formal definitions, lemmas and proofs. The plugin is still under development. Its main current hallmark is a document-consistent interaction model, instead of the calculator-like approach usual for TEXmacs plugins. This means that the Coq code in the TEXmacs document is interpreted as one (consistent) Coq file: executing a Coq command in the document means to execute it in the context (state) of all the Coq commands before it.
