Overview

solgpc is an extremely fast parser for the GPC Scripting Language. solgpc leverages Logos for its Lexing, and a hand crafted, built from scratch parser for its power, and is intented to be used for LSP development with its highly detailed and easy to traverse AST.

Usage

Installation

cargo add solgpc

Implementation Example

use solgpc::lexer::Lexer;
use solgpc::parser::Parser;

fn main() {
    let source = "int var = 0; main { if(var) set_rgb(255, 255, 255); }";

    let mut lexer = Lexer::new(&source);
    let tokens = lexer.collect();

    let errors = parser.errors();
    if !errors.is_empty() {
        println!("Parser errors: {:?}", errors);
        println!("Full diagnostics: {:#?}", &parser.diagnostics);
    }

    println!("AST: {:#?}", &parser.ast);
}
