PathTo

A lightweight Swift path pattern matcher for URL-style routing — supports named parameters, optional segments, and splat wildcards.

Installation

Swift Package Manager

Add CodeMirror to your project using Xcode:

1. In Xcode, go to File → Add Package Dependencies...
2. Enter the repository URL: https://github.com/jaywcjlove/swift-path-to.git
3. Click Add Package

Or add it to your Package.swift file:

dependencies: [
    .package(url: "https://github.com/jaywcjlove/swift-path-to.git", from: "1.0.0")
]

Features

• Named parameters: :name captures a single path segment.
• Optional segments: {/:id} marks a single segment as optional.
• Splat/wildcard: *rest captures remaining segments into an array.

Usage

import PathTo

Parameters

Parameters match arbitrary strings in a path by matching up to the end of a segment or up to any subsequent tokens. They are defined by prefixing the parameter name with a colon (:foo).

let fn = PathTo.match("/:foo/:bar")

if let r = fn("/test/route") {
    // r -> params: ["foo": "test", "bar": "route"]
    print(r.path) // "/test/route"
    print(r.params["foo"] as? String) // "test"
    print(r.params["bar"] as? String) // "route"
}

Wildcard

Wildcard parameters match one or more characters across multiple segments. They are defined the same way as regular parameters, but are prefixed with an asterisk (*foo).

let fn = PathTo.match("/*splat")
if let r2 = fn("/bar/baz") {
    // r -> params: ["splat": ["bar", "baz"]]
    print(r2.params["splat"] as? [String]) // ["bar", "baz"]
}

Optional

Braces can be used to define parts of the path that are optional.

let fn = PathTo.match("/users{/:id}/delete")
print(fn("/users/delete")?.params) // [:]
print(fn("/users/123/delete")?.params) // ["id": "123"]
