Ruckus: Racket for iOS(ruckus.defn.io) |
It does actually have a lot of R7RS support (like #!fold-case) however it doesn't seem to work with polar complex numbers (e.g; 2@1.5) or complex numbers with infnan (e.g; 3+inf.0i or +inf.0+3i).

Edit: JIT is under a flag, https://developer.apple.com/documentation/bundleresources/en...
edit: reported https://github.com/Bogdanp/Ruckus/issues/17
For Ruckus, I will reinstall Xcode, etc.
Other people have mentioned LispPad that is very good.

Good riddance
Don't you think knee jerk reactions like yours are part of the reason some people find it so hard to de radicalise?
> Polar complex number literals are actually not part of R7RS
I actually thought they were part of the spec. Specifically, I am referring to the last paragraph from section 6.2.5 of R7RS small <https://small.r7rs.org/attachment/r7rs.pdf>
This is the excerpt from the pdf:
6.2.5. Syntax of numerical constants
...
There are two notations provided for non-real complex numbers: the rectangular notation a+bi, where a is the real part and b is the imaginary part; and the polar no- tation r@θ, where r is the magnitude and θ is the phase (angle) in radians. These are related by the equation a + bi = r cos θ + (r sin θ)i. All of a, b, r , and θ are real numbers.
