underscore_args

Macro for underscore named argumet syntax, aka Dyon.

This library requires Rust 2018 nightly and only works for functions, not methods.

By naming a function line__color_from_to, one can call it like this:

ignore args!(line(color: [1.0; 4], from: [0.0, 0.0], to: [100.0, 100.0]))

• Double underscore after function name and before the name of the first argument
• Single underscore separating arguments

Example

```rust

![feature(concat_idents)]

use underscore_args::args;

[allow(nonsnakecase)]

fn line_colorfromto(color: [f32; 4], _from: [f32; 2], _to: [f32; 2]) {}

args!(line(color: [1.0; 4], from: [0.0, 0.0], to: [100.0, 100.0])); ```
