Code generation for Localizable.strings file for Swift

This application generates constants with keys from Localizable.strings file. If you don't need to use R.swift or SwiftGen but just need to have constants from your Localizable.strings, you can try this app!

It will generate namespaces from your constants, so, for such strings as "GENERAL_BTN_OK" you will not have .general_btn_ok constant, but General.Btn.ok.

You can do the same with SwiftGen and templates. Probably it will be better for using, such as it can generates code for another resources as well.

This app parses .strings file and separates keys by your separator (you can set up it with -sc flag, by default is .) and generates enums with the keys.

For example:

GENERAL_BTN_OK -> Localizations.General.Btn.ok
preferences.updates.last_update -> Localizations.Preferences.Updates.last_update

Also, it will generates localized function for these constants. By default it just contains NSLocalizedString(rawValue, comment: ""), but you can override it as you want.

Example of generated enums:

enum Localizations: String, Localizable {
  case alert = "alert"//or "ALERT", if you prefer to use this style
  
  enum General {
    enum Btn: String, Localizable {
      case ok = "general.btn.ok"//or "GENERAL_BTN_OK"
      case yes = "general.btn.yes"//or "GENERAL_BTN_YES"
    }
    enum Error: String, Localizable {
      case title = "general.error.title"//or "GENERAL_ERROR_TITLE"
    }
  }
}

And you can use it as you want, you can use it for translating: myLabel.text = Localizations.General.Btn.yes.localized
Or just if you need to know key: Localizations.General.Btn.yes.rawValue

This application contains a few flags, all of them are optional.
Example of usage: locgen -i ./en.lproj/Localizable.strings -o Localizable.swift -cs \".\" -so ./Localizations+Strings.swift\n"
Where:
-i: Input Localizable.strings file. Default value is Localizable.strings in current directory.
-o: Output file where generated strings should be placed. Default value is Localizable.swift in current directory.
-cs: String with characters which should be used for separating modules. Default is "."
-so: Support output file. IF this file exists already, this application will not replace it. This file contains default implementation for localized function. You can change it if you have another localization logic (for example, get translation from specific table). Default value is Localiztions+Strings.swift in current directory.

You can add this app to directory with your project and add new script to Build Phases before Compile Sources. Shell: /bin/sh
Example: ./locgen -i project/Resources/en.lproj/Localizable.strings -o project/Sources/View/Utils/Localizations.swift -so project/Sources/View/Utils/Localizations+String.swift
So, your constants will be always updated and you will know, if some strings are changed.
