TeXmacs is currently composed of 250 scheme files for \sim 60000 lines of 
scheme. Guile is used for customization and for other operations which do not 
require special performance. All the rest of the program is written in C++, in 
particular the typesetter and the GUI code. It has a slightly customized module 
system and features contextual overloading of functions (a function can be 
redefined to act differently is some condition is met without modifying the 
module which implemented the base behaviour). We would like to preserve the 
current system as much as possible. Moreover we want also to be compatible with 
previous versions of Guile (now we support Guile 1.4 up to Guile 1.8). The code 
does not depend very much on specific Guile features a part form the module 
system.

TeXmacs codebase is hosted at savannan 
(https://savannah.gnu.org/projects/texmacs/).  Check out the svn trunk  via

svn co svn://svn.savannah.gnu.org/texmacs/trunk

then you can find the scheme script in trunk/src/TeXmacs/progs

at boot C++ evaluate init-texmacs.scm which in turn bootstrap the custom module 
system defined in kernel/boot.scm and start to load modules. We have a facility 
to lazy load modules since in old machines the bootstrap of the scheme code is 
too slow. 
With the current svn you will not be able to build TeXmacs with Guile 2.0. If 
you are interested in that I will tell you how to do.

I still do not know very well the scheme code (almost all of it has been 
written by the main developer, Joris van der Hoeven).
