Recursively find files in a directory using globs.

This crate is now in a perpetual maintnance mode and new users should probably cosider using glob.

This crate was origially written years ago, when glob was a very differet crate, before it was adopted by the rust-lang org.

Nowadays glob is much better, and overall better maintained, but there are a few features that it does not seem to have (based on glob 0.3.1):

• The glob crate does not support having {a,b} in patterns.
• globwalk can match several glob-patterns at the same time.
• globwalk supports excluding results with !. (negative patterns)
• glob searches for files in the current working directory, whereas globwalk starts at a specified base-dir.

To use this crate, add globwalk as a dependency to your project's Cargo.toml:

[dependencies]
globwalk = "0.9.1"

The following piece of code recursively find all png, jpg, or gif files:

extern crate globwalk;

use std::fs;

for img in globwalk::glob("*.{png,jpg,gif}").unwrap() {
    if let Ok(img) = img {
        println!("{:?}", img.path());
    }
}
