p-macro

Tired of typing {:?}? This crate defines a macro p!() shorter to type than println!(), for your debugging needs.

Usage

Add this to your Cargo.toml:

toml [dependencies] p-macro = "*"

And use like this:

```rust

[macrouse] extern crate pmacro;

fn main() { let x = 5; let y = 2; p!(x + y); // same as println!("x + y = {:?}", x + y); p!(x, y); // same as println!("x = {:?}, y = {:?}", x, y); p!(); // same as println!(""); } ```

It does other things too. With a colon you disable printing the source code snippet:

rust p!(:10, :"a"); // same as println!("{:?} {:?}", 10, "a");

It accepts multiple lines too:

```rust let (a, b, c) = (1, 2, 3);

p! { a, b, c; a + b, 0, 1; }; // same as: // println!("a = {:?}, b = {:?}, c = {:?}", a, b, c); // println!("a + b = {:?}, 0 = {:?}, 1 = {:?}", a + b, 0, 1); ```

Strings are printed with quotes. If this is undesirable, prefix them with an _. This will make the macro use Display instead of Debug.

rust p!(_"Test"); // same as println!("{}", "Test"); let a = "x"; p!(_ a); // if necessary insert a space

To run the file on the examples folder, type cargo run --example print.
