error: `OrParser` does not name a structure

[bjadamson]

Hey, I'm getting this error when trying to combine my own parser using any of the macros, do you have any ideas on maybe I'm doing incorrectly?

#[phase(plugin)] 
extern crate peruse;
extern crate peruse;
use self::peruse::parsers::literal;

fn mm() {
    let dddd = or!(literal(A), literal(B));
}

The full error I get from trying to compile this:

Yeah that's a bug with the macros not properly namespacing the parsers. I'll have that fixed shortly.

[bjadamson]

Oh, okay. Thanks, is there any way to work around it in the meantime?

[DanSimon]

I just pushed a fix to master that should resolve the issue.

[bjadamson]

Ok I pulled in your patch (thanks btw!) and got this:

let p = or!(literal(A), literal(B));

[DanSimon]

Very odd, I'm not able to reproduce this error. Try doing cargo clean and then cargo build. I've run into issues before when updating without doing a clean.

[bjadamson]

Tried it, no dice! I have this though, could you try it on your box?

Weird, that works fine for me. The only changes I had to make to your code were add #![feature(plugin)] at the top and a main fn. Also my Cargo.toml looks like:

[package]

name = "test"
version = "0.0.1"
authors = [ "Your name <you@example.com>" ]

[[bin]]

name = "test"
path = "src/test.rs"

[dependencies.peruse]

git = "https://github.com/DanSimon/peruse.git"

Also just a heads up, the latest Rust nightly just broke peruse because of the new enum namespacing, I'll have that fixed soon fixed.
