+# rlua-searcher
+
+`require` Lua modules by name
+
+## 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
+
+```rust
+use rlua_searcher::AddSearcher;
+
+fn main() {
+    let lume = read_lume_to_string();
+    let name = "lume";
+    let map = HashMap::new<String, String>();
+    map.insert(name, lume);
+
+    let lua = Lua::new;
+
+    let hello = lua.context::<_, rlua::Result<_>>(|lua_ctx| {
+        lua_ctx.add_searcher(map)?;
+        Ok(lua_ctx.load(r#"require("lume")"#).eval()?)
+    }).unwrap();
+
+    // prints "hello lume"
+    println!("{}", hello);
+}
+
+fn read_lume_to_string() -> String {
+    r#"return "hello lume""#.to_string()
+}
+```
