sync-code

Synchronize code blocks between different files.

It can replace macros in certain scenarios. For example, when your code isn’t duplicated many times but the design is relatively complex (e.g., involving generics), using sync-code instead of a macro will give you much better readability and easier maintenance. Features like Go-to-definition and intelligent auto-completion also work properly without using macros.

Usage

Cargo.toml:

cargo add --build sync-code

See crate.

build.rs:

fn main() {
    sync_code::Builder::new()
        .add("src/target1.rs", "src/source1.rs")
        .add("src/target2.rs", "src/source2.rs")
        .sync();
}

your_code.rs:

// $sync block_name

fn code_you_want_to_sync() {
}

// $sync end
