Manifest Dir Macros
====================
[](https://github.com/magiclen/manifest-dir-macros/actions/workflows/ci.yml)
This crate provides function-like macros to check or operate paths relative to **CARGO_MANIFEST_DIR** at compile time.
## Examples
```rust
#[macro_use] extern crate manifest_dir_macros;
println!(path!("Cargo.toml"));
println!(path!("src/lib.rs"));
println!(path!("src", "lib.rs"));
println!(path!("src", "lib.rs", "/bin"));
println!(path!("/usr"));
println!(exist_path!("Cargo.toml"));
println!(directory_path!("src"));
println!(not_directory_path!("Cargo.toml"));
println!(file_path!("Cargo.toml"));
println!(relative_path!("Cargo.toml"));
println!(directory_relative_path!("src"));
println!(not_directory_relative_path!("Cargo.toml"));
println!(file_relative_path!("Cargo.toml"));
// The `tuple` feature allows these macros to support inputting nested literal string tuples, which is useful when you want to use these macros inside a `macro_rules!` macro and concatenate with other literal strings.
// `$x:expr` matchers can be used in these macros thus.
#[cfg(feature = "tuple")]
{
println!(path!(("foo",)));
println!(path!(("foo", "bar")));
println!(path!("a", ("foo", "bar")));
println!(path!(("foo", "bar"), "a"));
println!(path!(("foo", "bar"), ("a", "b")));
println!(path!(("foo", "bar", ("a", "b")), ("c", "d")));
}
```
