# Localization 
This is a python script that downloads localization strings and CI color information from a public [Google Sheet](https://docs.google.com/spreadsheets) and generates resource files for iOS and Android projects.

## Installation

    pip3.8 install googlesheettranslate

## Prerequisites

Create a Google Sheet document with sheets like [these](https://docs.google.com/spreadsheets/d/1672QPWDsxBtaX5hc5QgZhqBwLADMnPVEv7-wLB3g-ug):

![Example of a L10n table](Resources/sheet_l10n.png)
![Example of a colors table](Resources/sheet_colors.png)

Publish the sheeet to the web by pressing __File -> Publish to the web__. Select __Whole Document__ and __Website__. This gives the script access to the public JSON API of Google Docs.

Find the ID of your document by copying it from your browsers address bar.

## Usage

Create a `data_sync.config.json` in your project and populate it with the contents of the [example config](data_sync.config.json). Replace the `sheetId` with your own. You can modify the other settings to fit the needs of your project.

Then open a terminal at your project path and run `l10n_sync`. Look for your newly created resource files.

You can also copy [data_sync.py](Sources/data_sync.py) to your project and then run `python3 data_sync.py` when your config file is ready.

## Example

Have a look into the [Output folder](Output) for some example files generated by using the provided [configuration file](data_sync.config.json).

# Command line parameters

You generally run `sheet-localization` like this:

`python /path/to/sheet-localization/main.py /path/to/account_credentials.json SpreadSheetName TargetName`

1. `account_credentials.json` is a file you get after registering Google service account

1. `SpreadSheetName` is the name of the spreadsheet to open

   **Note**: Google service account must be given read permission to access the spreadsheet
   by sharing the document with the service account's email

1. `TargetName` can be one of `android`, `ios`, or `ios-swift`.

# Targets
## `android` target

`sheet-localization` generates `res/value-<lang>/strings.xml` hierarchy in the current directory.

## `ios` target

`sheet-localization` generates `<lang>.lproj/Localizable.strings` hierarchy in the current directory.

The script also generates `LocalizationConstants.h`, `LocalizationConstants.m` files with
translation constants.

## `ios-swift` target

`sheet-localization` generates `<lang>.lproj/Localizable.strings` hierarchy in the current directory.

The script also generates `LocalizationConstants.swift` files with translation constants
(actually, enum).

# Installation

The scripts require **Python 2.7+**.

***iOS generation will not work in Python 3+***

1. Linux

# Step by step guide

## 1. Clone sample Google spreadsheet

![Screenshot](readme/clone-action.png)
![Screenshot](readme/clone-title.png)

Clone [sample spreadsheet](https://goo.gl/41wame) to your Google Drive.

The sample document contains two mandatory pages:

1. `SRC` contains translations and keys
2. `CFG` contains configurations where keys are located and what row translations start at

These pages are required by the script, so make sure to keep them.

## 2. Create new Google API project

![Screenshot](readme/project-title.png)
![Screenshot](readme/project-created.png)

Go to [Google API console](https://console.developers.google.com) and create a new project.

## 3. Enable Google Drive API

![Screenshot](readme/enable-api-locate.png)
![Screenshot](readme/enable-api-enable.png)
![Screenshot](readme/enable-api-done.png)

Enable Google Drive API.

## 4. Create service account

![Screenshot](readme/credentials-type.png)
![Screenshot](readme/credentials-title.png)
![Screenshot](readme/credentials-json.png)

Create service account credentials for a `Web server` to access `Application data`

Name the service account and give it `Project -> Editor` role.

Upon account creation you should get a special JSON, which contains all necessary credentials.

## 5. Allow service account to read the spreadsheet document

![Screenshot](readme/share.png)

The JSON you downloaded looks like this:
```
{
  "type": "service_account",
  "project_id": "localization-173405",
  "private_key_id": "d37cdb95af7f817a05c",
  "private_key": "-----BEGIN PRIVATE KEY-----\nMIIEvAIBADANBgkqhkiG9w0BAQEFAASCBKYwggSiAgEAAoIBAQCO8ACoDvAG0q8R\xg3bQzHYCVrEDBcBFkfJ4d8dfy9FdIS++p3XvmLOWnFyMreQTPh1\njmx7jdmDpEwZHNZrj2dYYf0Xta8A0wxdejqUmNq4CyOBqTzomqCdzu36qBp8szUk\nN1l9G9u+rLcm9J/BlinOeA==\n-----END PRIVATE KEY-----\n",
  "client_email": "localization@localization-173405.iam.gserviceaccount.com",
  "client_id": "1016040",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://accounts.google.com/o/oauth2/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/localization%40localization-173405.iam.gserviceaccount.com"
}
```

To allow the service account to read your spreadsheet, you need to give `client email`
read permissions to your document. You can do it in sharing settings.

## 6. Generate Android localization files

![Screenshot](readme/android.png)

Go to the directory of your choice and
generate Android localization files with the following commands:

`cd /path/to/android/project`

`python /path/to/sheet-localization/main.py /path/to/service_account_credentials.json 'Spreadsheet Key' android`

This creates `res/values-<lang>/strings.xml` files with contents like this:

```
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="history">History</string>
<string name="notifications">Notifications</string>
<string name="favorite_places">Favourite places</string>
<string name="about">About</string>
<string name="wait_map_tag">wait_map_tag</string>
<string name="main_title_order"></string>
<string name="order_detail_title"></string>
<string name="action_im_here">I'm here</string>
<string name="action_get_order">Order</string>
</resources>
```

## 7. Generate iOS localization files

![Screenshot](readme/ios_run.png)

Go to the directory of your choice and
generate iOS localization files with the following commands:

`cd /path/to/android/project`

`python /path/to/sheet-localization/main.py /path/to/service_account_credentials.json 'Spreadsheet Key' ios`

This creates

1. `<lang>.lproj/Localizable.strings` files with contents like this:
    ```
    "Menu.Item.History" = "History";
    "Menu.Item.Notifications" = "Notifications";
    "Menu.Item.Favourites" = "Favourite places";
    "Menu.Item.About" = "About";
    "Profile.Email.Title" = "Email";
    "Profile.BirthDate.Title" = "Birth date";
    "Profile.ChangeAvatar.Title" = "Another photo";
    "Order.Address.Here" = "I'm here";
    "Details.Order" = "Order";
    ```
1. `LocalizationConstants.h` file with contents:
    ```
    /*!
    * @b en@: History

    * @b ru@: История

    * @b uk@: Історія

    */
    extern NSString * const trMenuItemHistory;

    /*!
    * @b en@: Notifications

    * @b ru@: Уведомления

    * @b uk@: Сповіщення

    */
    extern NSString * const trMenuItemNotifications;
    ```
1. `LocalizationConstants.m` file with contents:
    ```
    import "LocalizableConstants.h"
    NSString * const trMenuItemHistory = @"Menu.Item.History";
    NSString * const trMenuItemNotifications = @"Menu.Item.Notifications";
    NSString * const trMenuItemFavourites = @"Menu.Item.Favourites";
    NSString * const trMenuItemAbout = @"Menu.Item.About";
    NSString * const trProfilePhoneTitle = @"Profile.Phone.Title";
    NSString * const trProfileEmailTitle = @"Profile.Email.Title";
    ```

Localization constants help prevent string typos.

## 8. Generate iOS localization files for Swift

If you use `ios-swift` target, you get single `LocalizationConstants.swift`,
which looks like this:
```
import Foundation

enum L10n {
    case MenuItemHistory
    case MenuItemNotifications
    case MenuItemFavourites
    case MenuItemAbout
}


extension L10n: CustomStringConvertible {
    var description: String { return self.string }

    var string: String {
        switch self {
            case .MenuItemHistory:
                return L10n.tr(key: "Menu.Item.History")
            case .MenuItemNotifications:
                return L10n.tr(key: "Menu.Item.Notifications")
            case .MenuItemFavourites:
                return L10n.tr(key: "Menu.Item.Favourites")
            case .MenuItemAbout:
                return L10n.tr(key: "Menu.Item.About")
        }
    }

    private static func tr(key: String, _ args: CVarArg...) -> String {
        let format = NSLocalizedString(key, bundle: Bundle(for: BundleToken.self), comment: "")
        return String(format: format, locale: Locale.current, arguments: args)
    }
}

func tr(_ key: L10n) -> String {
    return key.string
}

private final class BundleToken {}
```

![Screenshot](readme/ios_run.png)

**Note**: file format is similar to what [SwiftGen](https://github.com/SwiftGen/SwiftGen)
generates.

You can later reference such a constant in code like this:
```
self.yourTextField.text = tr(.MenuItemAbout)
```
