Re: [Texmacs-dev] plugin for Haskell

Hi Max,

Yes supporting the jupyter protocol ( or trough localhost, like for the sessions via a web-navigator ) would be very useful for many applications ( iPython, Sage, Mathics, Haskell … ).

I wrote something that looks like the beginning of an Haskell plugin, but it would have to be improved ( particularly the control of the process, that in some situations have to be manually killed ! )

Hi Bertrand,
in principle yes even if right now I’m busy hacking the Qt port to track down some bugs and update to Qt 5.0. I would also try to replace Guile with s7 Scheme which seems more easy to maintain and as fast (wrt. Guile 1.8).

At some point I though a bit about the plugins and felt that TeXmacs need to support the jupyter protocol (https://jupyter.org), this would make it a perfect frontend for iPython and iHaskell for example but we will give us access to many other systems supporting that protocol, see for example this list of maintained kernels for jupyter:

https://github.com/jupyter/jupyter/wiki/Jupyter-kernels

It would make perfect sense to me and does not seem so difficult.

Hi,

Are you still interested in such a project ?

WYSIWYG literate programming
Massimiliano Gubinelli  27, 2009; 10:31am

Hi, 
I would like to "advertise" TeXmacs (http://www.texmacs.org/) to the Haskell comunity as a possible front-end for literate programming in Haskell (and GHCI interaction). TeXmacs is a system which allows the production of documents featuring high quality typesetting (comparable to TeX) and high level of customizability (a la Emacs). It does not rely on TeX for the typesetting (but can export to Latex, HTML, etc..). It is written in C++ (unfortunately not Haskell) and use Scheme as extension language (specifically Guile). It has been in use for at least 10 years and has plugins for many external applications like Pari, Axiom, Maxima, Octave, R, Yacas, etc... 

From the webpage: "GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content (text, graphics, mathematics, interactive content, etc.). The rendering engine uses high-quality typesetting algorithms so as to produce professionally looking documents, which can either be printed out or presented from a laptop." 

It would be nice to develop a pluging for GHC/GHCI to allow "direct" literate programming style with high-quality rendering. (If someone want to try before I find the time to do it myself.... )
