This document describes the hooks I added to Maxima in September 2003
to aid interfaces to external programs such as TeXmacs.
-- James Amundson 

Hooks for prompts
-----------------

*prompt-prefix* : string printed at the beginning of each prompt
*prompt-suffix* : string printed at the end of each prompt

TeXmacs example:
(setf *prompt-prefix* "channel:promptlatex:\\red ")
(setf *prompt-suffix* "\\black")

(The preceding lines contain control characters.)

Hooks for display
-----------------

*general-display-prefix* : string printed before each displayed output label
                           Exactly what that means my need refinement.

*maxima-prolog* : string printed at the beginning of a Maxima session
*maxima-epilog* : string printed at the end of a Maxima session

TeXmacs example:

(setf *general-display-prefix* "verbatim:")
(setf *maxima-prolog* "verbatim:")
(setf *maxima-epilog* "latex:\\red The end\\black")

(Again, the preceding lines contain control characters.)

Alternate display functions
---------------------------

*alt-display2d* : function to be used to display maxima equations
                  when display2d is true

*alt-display1d* : function to be used to display maxima equations
                  when display2d is false

TeXmacs example:

(setf *alt-display2d* 'latex)

The function latex is defined as

(defun latex (x)
  (let ((ccol 1))
    (mapc #'myprinc
      (if (and (listp x) (cdr x) (equal (cadr x) "Is  "))
        (tex x '("$\\displaystyle ") '("$ ") 'mparen 'mparen)
        (tex x '("latex:$\\displaystyle ") '("$
") 'mparen 'mparen)))))
