PoEditor Android Gradle Plug-in

Simple plug-in that eases importing PoEditor localized strings to your Android project.

Purpose

This plug-in super-charges your Android project by providing tasks to download your localized strings from the PoEditor service into you Android project. It also provides a built-in syntax to handle placeholders to enhance the already awesome Android support from PoEditor.

Setting Up

In your main build.gradle, add jitpack.io repository in the buildscript block and include the plug-in as a dependency:

Groovy

buildscript {
    repositories { 
        maven { url "https://jitpack.io" }
    }
    dependencies {
        classpath "com.github.hyperdevs-team:poeditor-android-gradle-plugin:2.3.0"
    }
}

Kotlin

buildscript {
    repositories { 
        maven("https://jitpack.io")
    }
    dependencies {
        classpath("com.github.hyperdevs-team:poeditor-android-gradle-plugin:2.3.0")
    }
}

How to use

Apply and configure the plug-in in your app's build.gradle file:

Groovy

apply plugin: "com.android.application"
apply plugin: "com.hyperdevs.poeditor"

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
}

Kotlin

plugins {
    id "com.android.application"
    id "com.hyperdevs.poeditor"
}

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
}

The complete attribute list is the following:

Attribute	Description
`apiToken`	PoEditor API Token.
`projectId`	PoEditor project ID.
`defaultLang`	(Optional) The lang to be used to build default `strings.xml` (`/values` folder). Defaults to English (`en`).
`defaultResPath`	(Since 1.3.0) (Optional) Path where the plug-in should dump strings. Defaults to the module's default (or build variant) `res` path.
`enabled`	(Since 1.4.0) (Optional) Enables the generation of the block's related task. Defaults to `true`.
`tags`	(Since 2.1.0) (Optional) List of PoEditor tags to download. Defaults to empty list.
`languageValuesOverrideMap`	(Since 2.2.0) (Optional) Map of `language_code:path` entries that you want to override the default language values folder with. Defaults to empty map.
`minimumTranslationPercentage`	(Since 2.3.0) (Optional) The minimum accepted percentage of translated strings per language. Languages with fewer translated strings will not be fetched. Defaults to no minimum, allowing all languages to be fetched.

After the configuration is done, just run the new importPoEditorStrings task via Android Studio or command line:

./gradlew importPoEditorStrings

This task will:

Download all strings files (every available lang) from PoEditor given the api token and project id.
Process the incoming strings to fix some PoEditor incompatibilities with Android strings system.
Create and save strings.xml files to /values-<lang> (or /values in case of the default lang). It supports region specific languages by creating the proper folders (i.e. /values-es-rMX).

Enhanced syntax

The plug-in enhances your PoEditor experience by adding useful features over your project by adding some custom syntax for certain tasks.

Variables

The plug-in does not parse string placeholders, instead it uses variables with a specific markup to use in PoEditor's string definition: it uses a double braces syntax to declare them. This allows more clarity for translators that use the platform, since it allows them to know what the placeholders really mean and better reuse them in translations.

For example, the PoEditor string:

welcome_message: Hey {{user_name}} how are you

will become, in strings.xml

<string name="welcome_message">Hey %1$s how are you</string>

If you need more than one variable in the same string, you can also use ordinals. The string:

welcome_message: Hey {1{user_name}} how are you, today offer is {2{current_offer}}

will become, in strings.xml

<string name="welcome_message">Hey %1$s how are you, today offer is %2$s</string>

This way you can change the order of the placeholders depending on the language:

The same string, with the following Spanish translation:

welcome_message: La oferta del día es {2{current_offer}} para ti, {1{user_name}}

will become, in values-es/strings.xml

<string name="welcome_message">La oferta del día es %2$s para ti, %1$s</string>

Tablet specific strings

You can mark some strings as tablet specific strings by adding _tabletsuffix to the string key in PoEditor. The plug-in will extract tablet strings to its own XML and save it in values-<lang>-sw600dp.

If you define the following string in PoEditor: welcome_message: Hey friend and welcome_message_tablet: Hey friend how are you doing today, you look great!

The plug-in will create two strings.xml files:

/values/strings.xml

<string name="welcome_message">Hey friend</string>

/values-sw600dp/strings.xml

<string name="welcome_message">Hey friend how are you doing today, you look great!</string>

Handling multiple flavors and build types

Sometimes we might want to import different strings for a given flavor (for example, in white label apps, we could have different string definitions depending on the brand where they're used). The plugin supports this kind of apps by providing specific configurations via the poEditorConfig block.

Let's see an example configuration:

Groovy

poEditor {
    // Default config that applies to all flavor/build type configurations. 
    // Also executed when calling 'importPoEditorStrings'
}

android {
    // If you have the following flavors...
    flavorDimensions 'type'
    productFlavors {
        free { dimension 'type' }
        paid { dimension 'type' }
    }

    poEditorConfig {
        free {
            // Configuration for the free flavor, same syntax as the standard 'poEditor' block
        }
        paid {
            // Configuration for the paid flavor, same syntax as the standard 'poEditor' block
        }
        debug {
            // Configuration for the debug build type, same syntax as the standard 'poEditor' block
        }
        release {
            // Configuration for the release build type, same syntax as the standard 'poEditor' block
        }
    }
}

Kotlin

poEditor {
    // Default config that applies to all flavor/build type configurations. 
    // Also executed when calling 'importPoEditorStrings'
}

android {
    // If you have the following flavors...
    flavorDimensions("type")

    productFlavors {
        register("free") { setDimension("type") }
        register("paid") { setDimension("type") }
    }

    poEditorConfig {
        register("free") {
            // Configuration for the free flavor, same syntax as the standard 'poEditor' block
        }
        register("paid") {
            // Configuration for the paid flavor, same syntax as the standard 'poEditor' block
        }
        register("debug") {
            // Configuration for the debug build type, same syntax as the standard 'poEditor' block
        }
        register("release") {
            // Configuration for the release build type, same syntax as the standard 'poEditor' block
        }
    }
}

Each flavor (free and paid) and build type (debug and release) will have its own task to import strings for said configuration: importFreePoEditorStrings, importPaidPoEditorStrings, importDebugPoEditorStrings and importReleasePoEditorStrings.

Now the importPoEditorStrings task will import the main strings configured in the poEditor block and also the strings for each defined flavor or build type.`

Handling library modules

Requires version 1.3.0 of the plug-in

You can also apply the plug-in to library modules. Here's an example: Apply and configure the plug-in in your library's build.gradle file:

Groovy

apply plugin: "com.android.library"
apply plugin: "com.hyperdevs.poeditor"

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
}

Kotlin

plugins {
    id "com.android.library"
    id "com.hyperdevs.poeditor"
}

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
}

You can also apply flavor and build type-specific configurations as you would do when setting them up with application modules. The plug-in will generate the proper tasks needed to import the strings under your module: :<your_module>:import<your_flavor_or_build_type_if_any>PoEditorStrings

Disabling task generation for specific configurations

Requires version 1.4.0 of the plug-in

There may be some cases where you only want certain configurations to have a related task. One of these examples may be to only have tasks for the configured flavors or build types, but you don't want to have the main poEditor block to download any strings. For these cases you have the enabled variable that you can set to false when you want to disable a configuration.

Keep in mind that, if you disable the main poEditor block, you'll need to enable each specific configuration separately since they inherit the main block configuration. Let's see how this works:

Groovy

poEditor {
    // Default config that applies to all flavor/build type configurations. 
    // Also executed when calling 'importPoEditorStrings'
    enabled = false // This'll disable task generation for every configuration.
    apiToken = "your_common_api_token"
}

android {
    flavorDimensions 'type'
    productFlavors {
        free { dimension 'type' }
        paid { dimension 'type' }
    }

    poEditorConfig {
        free {
            // Specific configuration for the free flavor
            enabled = true // Explicitly enabled since the main block disables task generation
            projectId = 12345
        }
        paid {
            // Specific configuration for the paid flavor
            enabled = true // Explicitly enabled since the main block disables task generation
            projectId = 54321
        }
    }
}

Kotlin

poEditor {
    // Default config that applies to all flavor/build type configurations. 
    // Also executed when calling 'importPoEditorStrings'
    enabled = false // This'll disable task generation for every configuration.
    apiToken = "your_common_api_token"
}

android {
    // If you have the following flavors...
    flavorDimensions("type")

    productFlavors {
        register("free") { setDimension("type") }
        register("paid") { setDimension("type") }
    }

    poEditorConfig {
        register("free") {
            // Specific configuration for the free flavor
            enabled = true // Explicitly enabled since the main block disables task generation
            projectId = 12345
        }
        register("paid") {
            // Specific configuration for the paid flavor
            enabled = true // Explicitly enabled since the main block disables task generation
            projectId = 54321
        }
    }
}

Handling tags

Requires version 2.1.0 of the plug-in

You can also select the tags that you want strings to be downloaded from PoEditor, based on the tags that you defined in your PoEditor project.

Groovy

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
    tags = ["tag1", "tag2"] // Download strings with the specified tags
}

Kotlin

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
    tags = listOf("tag1", "tag2")
}

Overriding default values folder for specific languages

Requires version 2.2.0 of the plug-in

Sometimes you may want to override the default values path where the plug-in stores the downloaded strings. For example, you may have a project where you have custom languages suited to your app flavors in PoEditor (let's say free and paid). The plug-in would create two folders in your app's res folder (values-free and values-paid) by default; this would not be ideal if you want the string values to their respective flavors.

You can add the parameter languageValuesOverridePathMap to your poEditor or poEditorConfig block to change the path of the values folder where the strings file will be stored for a given language code:

Groovy

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
    languageValuesOverridePathMap = [
            "free" : "${rootDir}/app/src/free/res/values", 
            "paid" : "${rootDir}/app/src/paid/res/values"
    ]
}

Kotlin

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
    languageValuesOverridePathMap = mapOf(
        "free" to "${rootDir}/app/src/free/res/values",
        "paid" to "${rootDir}/app/src/paid/res/values"
    )
}

Tweaking minimum translation percentages

Requires version 2.3.0 of the plug-in

The plug-in also allows setting a minimum percentage of translated strings to download languages. This is set-up with the minimumTranslationPercentage parameter in your poEditor or poEditorConfig blocks:

Groovy

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
    minimumTranslationPercentage = 85
}

Kotlin

poEditor {
    apiToken = "your_api_token"
    projectId = 12345
    defaultLang = "en"
    minimumTranslationPercentage = 85
}
