Hi there,

I'm new to rust and I'd like to use shiny as a tool to learn the language. However, I'm not able to compile even a simple test.

When I try to compile my dummy project (cargo build) I get this error:

   Compiling shiny v0.1.3
error: box expression syntax is experimental; you can call `Box::new` instead. (see issue #27779)
   --> /root/.cargo/registry/src/github.com-1ecc6299db9ec823/shiny-0.1.3/src/lib.rs:120:9

    |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    = help: add #![feature(box_syntax)] to the crate attributes to enable

My test code is basically one of your examples:

#![feature(box_syntax)]
#![feature(plugin)]
#![plugin(shiny)]

#[cfg(test)]
mod test {
  describe!(
    before_each {
      let awesome = true;
    }

    it "is awesome" {
      assert!(awesome);
    }

    it "injects before_each into all test cases" {
      let still_awesome = awesome;
      assert!(still_awesome);
    }
  )
}

and my cargo file is just this:

[package]
name = "shiny test"
version = "0.0.1"
authors = ["me"]
license = "MIT / Apache-2.0"

[dependencies]
shiny = "0.1.3"

PS:

• cargo 0.13.0-nightly (b931a0f 2016-09-11)
• gcc version 4.9.2 (Debian 4.9.2-10)

Thanks a lot

As @milgner noticed this is broken with the latest Rust nightly build. This makes everything compile again. And even though the tests pass I don't really know if the functionality has changed or not.

It is now broken under the current stable version, but due to the usage of #![feature(...)] it couldn't be compiled with the stable compiler anyway.

Hey @farcaller. Thanks for writing this awesome package. Are you aware that @reem also built a similar project? You can find it here: https://github.com/reem/stainless

I think it would make sense to somehow merge the projects to end up with a better package in terms of maintaining and quality.

... and make cute little test babies ? :)

seems to have more activity / was first in my google searches ... might make sense to join up and create a great framework together!

After the stable branch complained about the use of #![feature(plugin)], I built myself Rust 1.4.0 nightly. But I can't get shiny to work. Unfortunately I'm a total Rust noob, too (just want to write nice tests from the start), so it may be that I'm doing something elementary wrong. Nonetheless, here's the output:
