swat

Sweet attributes - a compact app for parsing files which specify several system setups in a convenient format and transforming them into a set of separate config files.
The app is an implementation of idea from cuco python package using swift programming language.

Installation

It is recommended to utilize the swift package manager for installation. To use the app include the following statement in your dependencies section of the Package.swift like this:

dependencies: [
    .package(url: "https://github.com/zeionara/swat.git", .branch("master"))
]

And in the list of dependencies for your target like this:

dependencies: ["Swat"]

Then, in your code you need to import the package and use it as you want (see file Examples/main.swift):

import Swat

struct Bar: ConfigWithDefaultKeys {
    let foo: Int
    let bar: String
}

struct Foo: ConfigWithDefaultKeys, RootConfig {
    let foo: Int
    let bar: Bar

    let name: String
}

let configs: [Foo] = try ConfigFactory().make(
    """
    foo: 17
    bar:
        - foo:
            - 17
            - 19
          bar:
            - qux
            - quux
        - foo:
            - 21
            - 23
          bar:
            - corge
            - grault
    name: demo
    """
)

configs.sorted{ $0.bar.foo < $1.bar.foo }.forEach{ print($0) }

The command produces the following output:

Foo(foo: 17, bar: Examples.Bar(foo: 17, bar: "qux"), name: "demo;bar=[\"bar\": [\"qux\", \"quux\"], \"foo\": [17, 19]];bar.bar=qux;bar.foo=17")
Foo(foo: 17, bar: Examples.Bar(foo: 17, bar: "quux"), name: "demo;bar=[\"bar\": [\"qux\", \"quux\"], \"foo\": [17, 19]];bar.bar=quux;bar.foo=17")
Foo(foo: 17, bar: Examples.Bar(foo: 19, bar: "qux"), name: "demo;bar=[\"bar\": [\"qux\", \"quux\"], \"foo\": [17, 19]];bar.bar=qux;bar.foo=19")
Foo(foo: 17, bar: Examples.Bar(foo: 19, bar: "quux"), name: "demo;bar=[\"bar\": [\"qux\", \"quux\"], \"foo\": [17, 19]];bar.bar=quux;bar.foo=19")
Foo(foo: 17, bar: Examples.Bar(foo: 21, bar: "corge"), name: "demo;bar=[\"foo\": [21, 23], \"bar\": [\"corge\", \"grault\"]];bar.bar=corge;bar.foo=21")
Foo(foo: 17, bar: Examples.Bar(foo: 21, bar: "grault"), name: "demo;bar=[\"foo\": [21, 23], \"bar\": [\"corge\", \"grault\"]];bar.bar=grault;bar.foo=21")
Foo(foo: 17, bar: Examples.Bar(foo: 23, bar: "corge"), name: "demo;bar=[\"foo\": [21, 23], \"bar\": [\"corge\", \"grault\"]];bar.bar=corge;bar.foo=23")
Foo(foo: 17, bar: Examples.Bar(foo: 23, bar: "grault"), name: "demo;bar=[\"foo\": [21, 23], \"bar\": [\"corge\", \"grault\"]];bar.bar=grault;bar.foo=23")

Generated config can be saved to local storage:

try configs.first!.write(to: Path.assets.appendingPathComponent("config.json"))

Then you can run the following command to fetch the dependencies and build the app:

swift build

To update the dependencies of your project invoke the following command:

swift package update
