This is my attempt at an implementation of the Aheui programming language in Rust. Aheui is an esolang written using the Korean Hangul script. Aheui code is as a two-dimensional grid of instructions, and code execution direction is controlled by the vowel of each Hangul syllable.
This repository includes a library for representing an Aheui program's execution state (known as libaheui), and an interpreter to run Aheui program files (known as rsaheui).
This implementation was written from scratch, only making use of the Aheui documentation and the reference JavaScript implementation without consulting its code. Because this implementation uses Rust and runs exclusively in the command line, it has some differences from the reference implementation:
- The extension protocol, which currently has no defined behavior in the documentation, acts as another queue storage structure.
- When a program prompts for user input (either a number or single character), the entire output is flushed with a newline character before prompting the user for an input.
- If the user provides an invalid input (e.g. blank input or a non-number input when prompted for a number), the interpreter will warn the user about their invalid input and prompt them once again.
- Attempting to push an invalid UTF-8 character to output is a fatal error that will terminate program execution prematurely.
- Arithmetic operations that cause overflow or underflow for
isizeare fatal errors that will terminate program execution prematurely. This may be subject to change. - Terminated programs are flushed with an additional newline character.
To build the program, simply run:
$ cargo build --releaseThe resulting interpreter binary rsaheui will be located at target/release/rsaheui. To run the interpreter binary:
$ ./rsaheui FILEFILE: the Aheui program file to run
