grok

The grok library allows you to quickly parse and match potentially unstructured data into a structed result. It is especially helpful when parsing logfiles of all kinds. This Rust version is mainly a port from the java version which in drew inspiration from the original ruby version.

Usage

Add this to your Cargo.toml:

toml [dependencies] grok = "0.1"

and this to your crate root:

rust extern crate grok;

Here is a simple example which stores a pattern, compiles it and then matches a line on it:

```rust extern crate grok;

use grok::Grok;

fn main() { // Instantiate Grok let mut grok = Grok::new();

// Insert a definition which might be a regex or an alias
grok.insert_definition("USERNAME", r"[a-zA-Z0-9._-]+");

// Compile the definitions into the pattern you want
let pattern = grok.compile("%{USERNAME}", false);

//  Match the compiled pattern against a string
match pattern.match_against("root") {
    Some(m) => println!("Found username {:?}", m.get("USERNAME")),
    None => println!("No matches found!"),
}

} ```
