The good thing with texmacs CAS sessions one can do a lot. Before jupyter I used a lot texmacs because CAS were very well integrated. Unfortunatly they don't integrate so well now, maybe the improvment of languages. As a wisiwig texmacs is better adapted for school and college than word or open office. The difficulty is to learn it properly which I didn't because my memory (RAM lol) is not good !

Any way I will try to progress and do something useful for kids.

have a good day :)

And thank you for sharing at the moment it is very important

Henri,
that's a great idea! Just this morning I showed to my 13yo son how to use
TeXmacs to type in his math exercises... he seems appreciate the better
quality wrt to Word :)

Thank you :)

I remenber I am french lol and I thaught of looking in french tutorial, in
fact there is a lot !

I am looking for drawing and graphics because the quarantine my son son 8
ans old has some maths to do. On w10 scheme seems the best integrated in
texmacs ?

I could use geogebra sagemath but I like texmacs for the nice presentation
and I would like to do a kind of tutorial for CE1 kids (8ans) and upper. Not
only in maths but in french and others languages (chinese my wife being).

Thank you all for your good help, it's important to not feel alone in these
moments

There is documentation in the manual about scheme:

Help -> Scheme extensions -> Overview of the scheme extension language.

For general knowledge about the language you can read any tutorial, there are
many here:

hth,

Two tutorials which I liked are

http://ds26gte.github.io/tyscheme/index.html

and

http://www.shido.info/lisp/idx_scm_e.html

(the last one seems simpler to me).


The reference to Guile (the implementation of Scheme use by TeXmacs) is

https://www.gnu.org/software/guile/docs/docs-1.8/guile-ref/

and one could use as well references to other implementations as one could
find some of the descriptions easier to follow (but one has to keep in mind
that the details, e.g. which functions are defined, are different)

MIT Scheme:

https://groups.csail.mit.edu/mac/ftpdir/scheme-7.4/doc-html/scheme_toc.html

Racket:

https://docs.racket-lang.org/

I have a quite rough knowledge of the language, but I start "feeling" that the way to use it is through function
composition, not through a sequence of instructions (like one does in Fortran for example). It "feels" like building
"things" with "objects" that become more complex (inside) as the work goes on but nevertheless "fit
together".

But maybe it is just my imagination ;-)
