I have been able to do the automatic loading. It is described in the 
help files, it took me a bit of time to follow the thread.

The right instruction is <use-module|([dir1 [dir2 ... dirn]] filename)> 
where the Scheme list indicates the path, which as far as I understood 
must be a subpath of one of the paths that TeXmacs know about 
(~/.TeXmacs/progs is one of them, so if dir1 is a subdirectory of 
~/.TeXmacs/progs, TeXmacs will find and load the Scheme files).

The style file itself can be put in the "user" directory of TeXmacs, 
that is again ~/.TeXmacs, under /packages, and it will appear in the 
"Document->Style-> Add package" menu.

I have not yet understood how to execute a macro only once inside 
TeXmacs, so the macros I use to define the list of formats get executed 
every time TeXmacs wants to (there is an update mechanism that I do not 
understand but I guess it is the general update mechanism of TeXmacs). 
The multiple execution has no effect, as the macros I wrote check for 
the existence of a format before adding it, but I would like to correct 
this and get the behaviour I want (only one execution for this macro). 
If anyone has a suggestion, thanks in advance.


I have updated the files at https://github.com/pireddag/formatRef and I 
think it is possible to use them even if they are not robust (multiple 
executions that I have mentioned above, missing checks on input) and 
incomplete.

Incompleteness that I see: it is not possible to define a format where 
the reference number is within parentheses, as the format string is 
always before the reference. I have in mind a solution with 
string-split, and perhaps for making it general I would need to 
understand better the TeXmacs format (with trees) and how to manipulate it.
