[Texmacs-dev] line numbering

[Massimiliano Gubinelli]

Dear Joris,  dear all,
 there were a question on the forum about line numbering (number every line on 
a page). I was thinking that was not possible without hacking the typesetter, 
but of course was not true. :) It came to my mind that there were the \datoms 
primitive and this seemed to be a nice application. I gave a 10 min try and 
seems to be *partially* working.

Also seems to show some problems : the numbering of sections inside the \datom 
is  not correctly positioned (very strange).
Maybe this is due to the fact that I used \shift. One would also have to give a 
size 0 to the numbers so that it does not affect the rest of the line. 


It would be nice to detect the beginning of a new page in order to reset the 
counter.
