library function

[DevulderJeanPaul]

hi,
nice tools!
it's great if in a future version, you add a example for library function like UpperCase for string
just for see how add more functions (math, string)..
thanks,

Hi, thanks! That is a good idea, I may add that as soon as I have some more time for this project :) Functions like this are not difficult to add, it is pretty similar to the writeln function, but these would not be statements but expressions as they return something (and thus can be evaluated). Great resource is https://craftinginterpreters.com/contents.html, definitely check that out (the author implements his own programming language, but the ideas are pretty clear). I am going to try to implement some string/math functions during the following month :)
