owoScript is a esoteric programming language that has code comprising entirely of OwO faces. owoScript programs are usually written in a higher level description language, and then compiled into OwO "bytecode." owoScript is Turing complete via a reduction from Brainfuck. owoScript is still in development, so may be buggy or change frequently.
Language Overview
owoScript syntax and more frequently updated command list can be found at the official owoScript documentation. However, the basics of the language will be detailed here: owoScript consists of 4 types of statements: number literals, commands, while loops, and if statements.
Number literals consist of the keyword literal, lit, or l followed by a single hex digit:
literal 4; literal b;
Commands are written with their specific keywords:
mult;
While loops are written as:
while {
//statements or nop;
}
If statements are written as:
if {
//statements or nop;
} else {
//statements or nop;
}
While loops will observe the top value of the stack without changing it, and continue if it is not 0 If statements pop the top value of the stack and execute the first block if it is not 0, or the second if it is 0
Commands
| Keyword | Pops | Pushes |
|---|---|---|
| literal x | None | hex value of x, x must be single hex digit (0-9, a-f) |
| add | a, b | a + b |
| sub | a, b | a - b |
| mult | a, b | a * b |
| div | a, b | a // b (floor division) |
| mod | a, b | a % b (modulus) |
| exp | a, b | a ^ b (exponent) |
| a | prints the character with code *a* | |
| printnum | a | prints the number literally |
| printstack | None | prints entire stack |
| input | None | number of character read from stdin |
| inputnum | None | decimal number read from stdin |
| lt | a, b | 1 if a < b else 0 |
| gt | a, b | 1 if a > b else 0 |
| eq | a, b | 1 if a == b else 0 |
| neq | a, b | 1 if a != b else 0 |
| cmp | a, b | if a == b: 0, if a > b: 1, if a < b: -1 |
| dupe | a | a, a (a repeated) |
| dupedeep | a | extend stack with last a values on stack |
| swap | a, b | b, a (top two values swapped) |
| push | a, b | puts a *b* layers deep in the stack |
| fetch | a | pulls the number *a* deep in the stack to the top |
| stacklength | None | length of stack |
| store | a, b | stores b in the *a* slot in the hashmap |
| get | a | pushes the value stored in *a* slot in the hashmap |
| stop | a | exits with return code a |
| fetchdupe | a, b | same as fetch but doesn't remove number from inside stack |
| pushdupe | a | same as push but doesn't remove number from top of stack |
| nop | None | no operation, used for code clarity in if/else statements |
| hexmult | a, b | a * 16 + b (hexadecimal digit appending) |
| printhash | None | prints entire hashmap |
Turing completeness
owoScript is proven turing complete via a simple reduction from brainfuck. The owoScript repository also contains an optimizing transpiler capable of generating owoScript from brainfuck code.
