Selya

SELYA (Special Esoteric Language for Young and Adult) -- it is esoteric language for everyone based on hex :D

Installation

cargo install selya --features clap

Syntax

So, probably, all of you already know, that in most programming languages such string as 0xA2 -- is it hexadecimal number

Well, Selya use it as often as it can :D

Every each hexadecimal number that is used you, is written to corresponding cell.

Default the carriage installed to first position, but you can change it with operator --> or <--

Operators

It is strange, that I begin this chapter after two operators description, but nevertheless

So, Selya has next operators:

1. --> and <-- -- shifts carriage of memory in the direction of the arrow;
2. [+] -- add the next value to the current cell (if cell is overflowed;
3. [^] -- addition modulo 2 of the next value with the current value in the cell;
4. [>] and [<] -- rotate memory in the specified direction;

In addition to Selya operators, it also has commands (not released):

1. I don't wanna talk about it, try to find it by yourself :D
2. zen -- write zen of the Selya

Rules

1. First value that you write -- memory size. Memory size can be greater or equal 0x0 and lower than 0xFFFF, another value cannot be recognized by parser
2. You can get the satanic power by 6 words :D

Errors

All the errors have the same kind as [Selya::Pipeline::{kind}]: {description}. Possible kinds of errors:

1. IoError -- selya interpreter cannot read your file;
2. ParserError -- cannot parse your file. It seems when you for examples write more than 4 digits in the number;
3. Memory::Overflow -- in the cell were written number more than 0xFFFF;
4. Memory::OutOfRange -- appear when you try shifts on the boundaries of memory;
5. Interpreter::UsingBinaryAsUnary -- after binary operator ([+] and [^]) there is no number.
