Coolie(苦力)
Coolie parse a JSON file to generate models (& their constructors).
Swift 2.1
test.json
:
{
"name": "NIX",
"detail": {
"age": 18,
"gender": null,
"is_dog_lover": true,
"is_cat_lover": false,
"skills": [
"Swift on iOS",
"C on Linux"
],
"motto": "爱你所爱,恨你所恨。"
},
"projects": [
{
"name": "Coolie",
"url": "https://github.com/nixzhu/Coolie"
}
]
}
Build coolie & run:
$ xcrun swiftc Sources/*.swift -o coolie
$ ./coolie test.json User
It will generate:
struct User {
struct Detail {
let age: Int
let gender: UnknownType?
let isCatLover: Bool
let isDogLover: Bool
let motto: String
let skills: [String]
static func fromJSONDictionary(info: [String: AnyObject]) -> Detail? {
guard let age = info["age"] as? Int else { return nil }
let gender = info["gender"] as? UnknownType
guard let isCatLover = info["is_cat_lover"] as? Bool else { return nil }
guard let isDogLover = info["is_dog_lover"] as? Bool else { return nil }
guard let motto = info["motto"] as? String else { return nil }
guard let skills = info["skills"] as? [String] else { return nil }
return Detail(age: age, gender: gender, isCatLover: isCatLover, isDogLover: isDogLover, motto: motto, skills: skills)
}
}
let detail: Detail
let name: String
struct Project {
let name: String
let url: String
static func fromJSONDictionary(info: [String: AnyObject]) -> Project? {
guard let name = info["name"] as? String else { return nil }
guard let url = info["url"] as? String else { return nil }
return Project(name: name, url: url)
}
}
let projects: [Project]
static func fromJSONDictionary(info: [String: AnyObject]) -> User? {
guard let detailJSONDictionary = info["detail"] as? [String: AnyObject] else { return nil }
guard let detail = Detail.fromJSONDictionary(detailJSONDictionary) else { return nil }
guard let name = info["name"] as? String else { return nil }
guard let projectsJSONArray = info["projects"] as? [[String: AnyObject]] else { return nil }
let projects = projectsJSONArray.map({ Project.fromJSONDictionary($0) }).flatMap({ $0 })
return User(detail: detail, name: name, projects: projects)
}
}
Pretty cool, ah?
