Prog Lang

Prog Lang is an interpreted programming language written in Rust, developed during the TulaHack 2024. It is designed to be as simple and as lightweight as possible. I have forked the original repository in order to preserve the exact version that we presented.

Notable Features

• Interpreted: Albeit slower than compiled languages, does not require an architecture-dependent compiler and can be run on any machine.
• Syntax: Designed to be as simple as possible. Basic features, basic syntax.
• Parsing Library: Utilizes pest.rs to parse the source code, enabling quick modifications to the grammar when needed.

Whats Next

• Objects
• Spanned error reporting
• More standard functions
• Improved stability

Getting Started

You can follow these simple steps to get started with Prog Lang:

1. Clone the Repository:

git clone https://github.com/im-fiv/prog-lang.git

2. Build the project:

cd prog-lang
cargo build --release

3. Run:

cargo run -- run file_name.prog

Syntax

The specifications of Prog Lang are still being considered, but here's the currently accepted syntax:

// this is a comment!
/* and so is this */

def variable_definition = "hello, world!"
def module_import = ("path goes here") -> import
def user_input = ("what is your favorite food?: ") -> input

variable_definition = "variable reassign!"

def function_definition = func(arg1, arg2) do
	return arg1 + arg2
end

def returning_void = func() do
	return void
end

def function_call = (2, 2) -> function_definition

if function_call == 4 then
	("math works!") -> print
end

while function_call < 15 do
	("while loop: ", function_call) -> print
	function_call = function_call + 1
end

Alternatively, the grammar file can be found at crates/prog-parser/src/grammar.pest
