Advanced Pattern Matching for Julia

Features:

• Matching against almost any data type with a first-match policy
• Deep matching within data types and matrices
• Variable binding within matches

For alternatives to Match, check out

• toivoh's PatternDispatch.jl for a more Julia-like function dispatch on patterns.

Installation

Use the Julia package manager. Within Julia, do:

Pkg.add("Match")

Usage

The package provides one macro, @match, which can be used as:

using Match

@match item begin
    pattern1              => result1
    pattern2, if cond end => result2
    pattern3 || pattern4  => result3
    _                     => default_result
end

It is possible to supply variables inside pattern, which will be bound to corresponding values.

See the documentation for examples of this and other features.
