Hello,
i just released a new version of Scheme+
Scheme+ is an extension of the syntax of the Scheme language. Scheme+ makes
it easy the assignment of Scheme objects in infix (works also in prefix)
notation with a few new operators ← (or <-), [ ],⥆ (or <+) .
https://github.com/damien-mattei/Scheme-PLUS-for-Guile
This new version adds operator precedence in the infix evaluator for
operators,procedures and macros (example: or , and).
Expressions like this can now be used in Scheme+:
{5 * 3 + 2}
17
{xp <- {x - v * t} / (sqrt {1 - v ** 2 / c ** 2})}
{ 4 + 3 * 2 - 19 < 0 - 4}
#t
{ #f or #f and (begin (display "BAD") (newline) #t)}
#f
Damien
