About translate-gpt

translate-gpt is a fastlane plugin that allows you to easily translate your iOS and Android app's strings using the OpenAI GPT API.

Features

Automatically detects the source language and translates to the desired target language.
Can take contextual information, such as comments in your code, into account to improve translation accuracy.
Can automatically skip strings that are already translated, improving performance and reducing costs.

Example

The following example demonstrates how to use translate-gpt in a Fastfile to translate an app's strings from English to French:

lane :translate_strings do
  translate_gpt(
    api_key: 'YOUR_API_KEY',
    target_language: 'fr'
  )
end

Options

The following options are available for translate-gpt:

Key	Description	Environment Variable
`api_key`	The API key for your OpenAI GPT account.	`GPT_API_KEY`
`model_name`	Name of the ChatGPT model to use	`GPT_MODEL_NAME`
`temperature`	What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. Defaults to 0.5	`GPT_TEMPERATURE`
`request_timeout`	Timeout for the request in seconds. Defaults to 30 seconds	`GPT_REQUEST_TIMEOUT`
`skip_translated`	Whether to skip strings that have already been translated. Defaults to `true`.	`GPT_SKIP_TRANSLATED`
`source_language`	The source language of the strings to be translated. Defaults to auto-detection.	`GPT_SOURCE_LANGUAGE`
`target_language`	The target language of the translated strings. Required.	`GPT_TARGET_LANGUAGE`
`source_file`	The path to the `Localizable.strings` or `strings.xml` file to be translated.	`GPT_SOURCE_FILE`
`target_file`	The path to the output file for the translated strings.	`GPT_TARGET_FILE`
`context`	Common context for the translation	`GPT_COMMON_CONTEXT`
`bunch_size`	Number of strings to translate in a single request.	`GPT_BUNCH_SIZE`

Note: I advise using bunch_size. It will reduce the number of API requests and translations will be more accurate.

Providing context

The TranslateGptAction allows you to provide additional context for your translation requests in two ways:

1. Using a common context

You can provide a common context for your project that will be used in all translation requests. This can be done by setting the common property when calling the TranslateGptAction. The common property should be a string that describes the context of your project.

translate_gpt(
  target_language: 'fr',
  common: "This is a mobile app for ordering food online"
)

2. Adding comments for specific keys

You can also add comments to your Localizable.strings file for specific keys. These comments will be included in the translation request for that key. To add a comment for a specific key, simply include a comment before the key in your Localizable.strings file.

/* This is a comment for KEY1 */
"KEY1" = "Value for KEY1";

When you run the TranslateGptAction, the comment will be included in the translation request for KEY1.

Authentication

translate-gpt supports multiple authentication methods for the OpenAI GPT API:

API Key

You can provide your API key directly as an option to translate-gpt:

translate-gpt(
  api_key: 'YOUR_API_KEY',
  target_language: 'fr'
)

Environment Variable

Alternatively, you can set the GPT_API_KEY environment variable with your API key:

export GPT_API_KEY='YOUR_API_KEY'

And then call translate-gpt without specifying an API key:

translate-gpt(
  target_language: 'fr'
)
