Command-Line Program for Translating i18n json using Google Cloud Translation API

This is a simple command-line program written in Go that uses the Google Cloud Translation API to translate i18n json with text from one language to another. The program takes in a JSON file containing text to be translated, source language, target language and output JSON file path as required command-line arguments.

Usage

To use the program, you'll need to have a Google Cloud service account and API key. You can create one by following the instructions in the Google Cloud documentation.

Once you have your credentials, you can run the program using the following command:

export GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH"

i18n-gt -input <inputfile> -source <source language> -target <target language> -output <outputfile>

where <inputfile> is the path to the input JSON file, <source language> is the code for the source language (e.g. "en" for English), <target language> is the code for the target language, <outputfile> is the path to the output JSON file

Input JSON Format

The input JSON file should contain an object, with property and value

Here's an example input JSON file:

{
  "title": "Welcome!",
  "pages": {
    "title": "Pages",
    "profile": {
      "title": "Profile page",
      "login": {
        "pasword": "password"
      }
    }
  }
}

Output JSON Format

The output JSON file will contain translated object

Here's an example output JSON file:

{
  "pages": {
    "profile": {
      "login": {
        "pasword": "hasło"
      },
      "title": "Strona profilowa"
    },
    "title": "Strony"
  },
  "title": "Powitanie!"
}

Dependencies

The program uses the following Go packages:

  • cloud.google.com/go/translate: The Google Cloud Translation API Go client library
  • golang.org/x/text/language: The Go standard library package for language code parsing
  • google.golang.org/api/option: The Google Cloud API option library

You can install these packages using the go get command:

go get cloud.google.com/go/translate
go get golang.org/x/text/language
go get google.golang.org/api/option

To build the program for multiple platforms, run the following command:

make build

This will compile the program and generate a binary file in the build/ directory.

To run the program in development mode, run the following command:

make dev

This will run the program with the input.json and account.json files provided and generate the output.json file.

Build Targets

The Makefile provides the following build targets:

  • build-linux-amd64: Build the program for Linux x64
  • build-linux-arm: Build the program for Linux ARM
  • build-darwin-amd64: Build the program for macOS x64
  • build-windows-amd64: Build the program for Windows x64
  • build: Build the program for all platforms
  • clean: Clean up generated binary files

Here's an example of how to build the program for a specific platform:

make build-linux-amd64

This will compile the program for Linux x64 and generate a binary file in the build/ directory.

TODO

  • Set up GitHub release workflow to automate binary file creation and release management.
