PathSlicer

Returns information about Nancy style path strings such as /rebels/{name}/{action}/.

Features

• [x] Turns Nancy style path into regular expression
• [x] Returns arguments for capture components
• [x] Allows to add custom path component types
• [ ] Support for case sensitivity
• [ ] Support for optional compoments
• [ ] Support for RegEx named capture groups

Integration

Requirements

• iOS 9.0+ / Mac OS X 10.9+ / tvOS 9.0+ / watchOS 2.0+
• Xcode 7.3+

Manually

You can also manually add PathSlicer to you project:

1. Download repository,
2. Drag Sources folder into you project’s tree.

Usage

let slicer = PathSlicer()

let path = "/rebels/{name}/{action}"
let pathDescription = slicer.getPathDescription(path)

The pathDescription variable contains following values:

pathDescription = {
    regex = "rebels\\/([^\\\\/]+?)\\/([^\\\\/]+?)(?:\\/(?=$))?$",
    arguments = [ "name", "action" ]
}

Suported segment patterns

Literal segments

Literal segments don’t contain any arguments and are matched as they are.

let slicer = PathSlicer()

let path = "/empire/darth_vader/choke"
let pathDescription = slicer.getPathDescription(path)

The pathDescription variable contains following values:

pathDescription = {
    regex = "/empire/darth_vader/choke(?:\\/(?=$))?$",
    arguments = [ ]
}

Capture segments

Capture segments allow to add parameters to the paths. Each capture segment is surrounded by { and }. Capture segments are returned in argument property of path description.

let slicer = PathSlicer()

let path = "/empire/{name}/{action}"
let pathDescription = slicer.getPathDescription(path)

The pathDescription variable contains following values:

pathDescription = {
    regex = "empire\\/([^\\\\/]+?)\\/([^\\\\/]+?)(?:\\/(?=$))?$",
    arguments = [ "name", "action" ]
}

RegEx segments

RegEx segments allows to define custom component machers. Right now named caupture groups of regular expression are not returned as arguments of path description.

let slicer = PathSlicer()

let path = "/can_be_jedi/(?<age>[\\d]{1,2})"
let pathDescription = slicer.getPathDescription(path)

The pathDescription variable contains following values:

pathDescription = {
    regex = "can_be_jedi/(?<age>[\\d]{1,2})(?:\\/(?=$))?$",
    arguments = [ ]
}
