Dear all,


with a bit of help from Massimiliano (thanks) I think I have understood 
how to interface a Scheme macro and a TeXmacs macro. I write here to 
double check that I have understood well and to see if there are other 
things that I should know.


The key thing is the conversion of macro parameters from tree (as they 
are in TeXmacs) to Scheme variables and vice-versa. The conversion in 
one way is performed by the function tree->stree, and in the opposite 
way by stree->tree.

For example the following function

(tm-define (testFunct str)
  (set! str (tree->stree str))
  (stree->tree (string-length str)))


when called using

<assign|testTexMac|<macro|str|<extern|testFunct|<arg|str>>>>


seems to work (I have tested it once ;-) ).


Is this generally working or there are some other things that I need to 
know? The  use of <quote-arg|x> for the argument x, which I found in 
http://www.texmacs.org/tmweb/manual/webman-styling.en.html obtains an 
effect different from tree->stree, right?


Thanks in advance,


Giovanni
