[Giovanni Piredda <address@hidden>]

Dear all,

I have improved a bit the package for TeXmacs that plots functions that 
I placed at https://github.com/pireddag/plotFun


- It can now plot several functions in the same graph (but all in blue :-) )

- Following up on a suggestion from Max, I am evaluating the arbitrary 
user-provided code that the program needs to plot the functions using a 
"safe module". In this module a restricted set of commands is available 
(I learnt about that from here: 
https://www.mail-archive.com/address@hidden/msg00963.html, as far as 
I understand for the Guile 2/3 series there is a different method).


I do not know how safe is the program now, but I hope that it is now 
difficult damaging your computer by placing "the wrong code" as an 
argument to the function-plotting macro. I would appreciate very much 
comments on the safety of the program, as I know very little (almost 
nothing) on this topic.

I have in mind to add a series of colors with which successive functions 
will be plotted - if/when I do that I will post again.

Giovanni
