Uiua () is a general-purpose array-oriented programming language with a focus on simplicity, beauty, and tacit code.

Uiua lets you write code that is as short as possible while remaining readable, so you can focus on problems rather than ceremony.

The language is not yet stable, as its design space is still being explored. However, it is already quite powerful and fun to use!

Uiua uses special characters for built-in functions that remind you what they do!

⚂ # Random number
⇡8 # Range up to
⇌ 1_2_3_4 # Reverse

I tried to go through the tutorial a year or so ago.

I can’t recall when, but there’s a point at which doing something normal/trivial in an imperative language requires all sorts of weirdness in Uiua. But they try to sell it as especially logical while to me they came off as completely in a cult.

It’s this section, IIRC: https://www.uiua.org/tutorial/More Argument Manipulation#-planet-notation-

When they declare

And there you have it! A readable syntax juggling lots of values without any names!

For

×⊃(+⊙⋅⋅∘|-⊃⋅⋅∘(×⋅⊙⋅∘)) 1 2 3 4

Which, if you can’t tell, is equivalent to

f(a,b,c,x) = (a+x)(bx-c)

With arguments 1, 2, 3, 4.

I wanted to like this, and have always wanted to learn APL or J (clear influences). But I couldn’t take them seriously after that.
