Esobsc: the esoteric version of ␣;

Esobsc is an implementation of ␣; for the esolang community.

How to use it

Install Rust and complile esobsc with cargo build --release.

To make your first esobsc program, create a source code file named hello.c and write this into it:

'Hello world!\n'⎕    ⍝ This prints “Hello world”

Run your program with cargo run -- hello.c

+ − × ÷ > = < — arithmetics
13 · ⇒ 13
666 13 ↔ ⇒ 13 666
42 19 ↓ ⇒ 42
9 ⇈ ⇒ 9 9
⍬ — creates an empty list
, — appends an element to a list
⍬1,⍘ ⇒ ⍬1
⎕ — print
∇ — fixed point combinator. It takes an init value and (a -> a bool) quotation and runs it while true
1`=`0?'OH MY GOD JC A BUG!\n':'My branching is argumentated\n'.⎕
(), [] — grouping, quotation
; — composition and concatenation
⍝ — a lamp

Q: How do I type all these symbols? I'm using ed and there's no ∇ on my keyboard.
A: It is hard to write esobsc code in ed. Consider using a text editor.
Q: I see strange squares instead of esobsc symbols. Why?
A: Probably your system lacks Unicode fonts required to display esobsc symbols correctly. Install fonts. Alternatively, your software may not have Unicode support. Never use software that doesn't support Unicode.
Q: Is esobsc turing-complete?
A: Yes. Proving it is left to the reader as an exercise.
