This crate is part of the Goscript project. Please refer to https://goscript.dev for more information.

It's a wapper of all the parts of the Goscript project. It also implements the standard library, the standard library part is still under development, only a few parts are implemented.

Example:

use std::path::{Path, PathBuf};
use go_engine::{Config, ErrorList, SourceReader, run};

fn run_file(path: &str, trace: bool) -> Result<(), ErrorList> {
let mut cfg = Config::default();
cfg.trace_parser = trace;
cfg.trace_checker = trace;
let sr = SourceReader::local_fs(PathBuf::from("../std/"), PathBuf::from("./"));
let result = run(cfg, &sr, Path::new(path), None);
if let Err(el) = &result {
el.sort();
eprint!("{}", el);
}
result
}
