My own wacky programming language, written in Rust

hug

My own lil easy-to-use programming language inspired by GDScript & Rust, focused on being beginner-friendly while providing advanced features and incredible speed.

Features

Currently working features are:

• External function calling (define dynamic library with @extern(location = "path_to_lib.so") module name, then a function with @extern function name;).
• Because of the prior feature, you can create Hug libraries in C or Rust. Tools are available for Rust libs.
• Very basic variables (no math yet, nor mutability)
• Lexer based off Rust's lexer
• Messy code that will need cleanup
• Interpreted by a VM (similair to how Java works)
• Bare bones core library with these variable types:
  • Int8 - Int128 - Sized integers
  • UInt8 - UInt128 - Sized unsigned integers (always positive)
  • Float32, Float64 - Sized floats
  • String - Text
  • Char - A single character (8 bits)
  • Function - Pointer to Hug function
  • ExternalFunction - Pointer to external (dynamically loaded) function

Usage

NOTE: The other/ directory contains a file for syntax highlighting in sublime text (not fully finished yet)

IMPORTANT: Currently, the Core library is compiled to a dynamic library, the extension differs per platform. Make sure to change this line in hug_core/hug/core.hug:

@extern(location = "target/debug/libhug_core.dylib") module core

To any of these depending on your platform:

Windows:

@extern(location = "target/debug/libhug_core.dll") module core

MacOS:

@extern(location = "target/debug/libhug_core.dylib") module core

Linux:

@extern(location = "target/debug/libhug_core.so") module core

No precompiled binaries are available yet, but you can run it yourself using:

cargo run -- <args for hug>

For a list of commands run:

cargo run -- --help

Running a .hug file:

cargo run -- run <file>

Running the unit test:

cargo test

And lastly, disabling debug output:

cargo run --release -- <args for hug>
