rlua-searcher

require Lua modules by name

(This is a fork of https://git.sr.ht/~ioiojo/rlua-searcher, I don't maintain this code, I just need to available on crates.io for other dependent packages.)

Description

Encode a Lua module as a HashMap of Lua strings indexed by module name. In an rlua::Context, pass the HashMap to add_searcher(), and require the module.

Synopsis

use rlua::Lua;
use rlua_searcher::{AddSearcher, Result};
use std::collections::HashMap;

fn main() {
    let lume = Cow::from(read_lume_to_string());
    let name = Cow::from("lume");
    let mut map = HashMap::new();
    map.insert(name, lume);

    let lua = Lua::new();

    let hello = lua
        .context::<_, Result<String>>(|lua_ctx| {
            lua_ctx.add_searcher(map)?;
            Ok(lua_ctx.load(r#"return require("lume")"#).eval()?)
        })
        .unwrap();

    // prints "hello lume"
    println!("{}", hello);
}

fn read_lume_to_string() -> String {
    r#"return "hello lume""#.to_string()
}
