#![no_std]

//!
//! # Reclone
//!
//! Minimal macro library to help with cloning objects into move closures
//!
//!
//! I've found that when building applications, you commonly have a set of Arcs representing   
//! state of some sort, and need to move it into a move closure
//!
//! This is annoying and leads to code like this:
//!
//!
//! ```rust
//!
//! let foo = ...;
//! let bar = ...;
//! let baz = ...;
//!
//! {
//!     let foo = foo.clone();
//!     let bar = bar.clone();
//!     let baz = baz.clone();
//!
//!     tokio::spawn(async move{
//!         // Use the variables
//!     });
//! }
//!
//! ```
//!
//! Now with reclone, this becomes, in my opinion, a little neater and less repetitive
//!
//!
//! ```rust
//! use reclone::cloned;
//!
//! let foo = ...;
//! let bar = ...;
//! let baz = ...;
//!
//!
//! cloned!(foo, bar, baz, {
//!     tokio::spawn(async move{
//!         // Use the variables
//!     });
//! });
//!
//!
//! ```
//!
//!
//! If you can't justify bringing this in as a dependency, you're welcome to directly inline   
//! the code in your codebase
//!
//!
//! ```rust
//! macro_rules! cloned {
//!     ($($var : ident ,)* $scope : block) => {
//!            {
//!                $(
//!                    let $var = $var.clone();
//!                 )*
//!                 $scope
//!         }
//!     }
//! }
//! ```
//!
//!

macro_rules! cloned {
    ($($var : ident ,)* $scope : block) => {
        {
            $(
                let $var = $var.clone();
            )*
            $scope
        }
    }
}

#[cfg(test)]
mod test {

    extern crate alloc;

    use crate::cloned;
    #[test]
    fn clone_arc() {
        use alloc::sync::Arc;

        let foo = Arc::new(10u32);
        let bar = Arc::new(20u32);

        cloned!(foo, bar, {
            core::mem::drop(foo);
            core::mem::drop(bar);
        });

        println!("Variables: {foo:?} {bar:?}");
    }
}
