Getting Started

Swift Package Manager

Add .package(url: "https://github.com/SwiftScream/URITemplate.git", from: "5.0.0") to your Package.swift dependencies

Usage

Template Processing

import ScreamURITemplate

let template = try URITemplate(string:"https://api.github.com/repos/{owner}/{repository}/traffic/views")
let variables = ["owner":"SwiftScream", "repository":"URITemplate"]
let urlString = try template.process(variables)
// https://api.github.com/repos/SwiftScream/URITemplate/traffic/views

When Things Go Wrong

Both template initialization and processing can fail; throwing a URITemplate.Error The error cases contain associated values specifying a string reason for the error and the index into the template string that the error occurred.

do {
    _ = try URITemplate(string: "https://api.github.com/repos/{}/{repository}")
} catch {
    // error.reason = "Empty Variable Name"
    // error.position = 29th character
}

Get variable names used in a template

let template = try URITemplate(string:"https://api.github.com/repos/{owner}/{repository}/traffic/views")
let variableNames = template.variableNames
// ["owner", "repository"]

Codable Support

URITemplate implements the Codable protocol, enabling easy serialization to or from JSON objects.

struct HALObject : Codable {
    let _links : [String:URITemplate]
}

Tests

The library is tested against the standard test suite, as well as some additional tests for behavior specific to this implementation. It is intended to keep test coverage as high as possible.
