Tarjem

Tarjem is a powerful CLI tool for managing translations in your projects. It simplifies the process of internationalization by generating type-safe code from YAML translation files.

tarjem ترجم is an arabic word means 'translate'

Features

• Tarjem uses fmt.Sprintf directly for precise formatting. This approach skips templates, which makes it faster and more efficient.
• Initialize translation files with a simple command
• Export translations to various programming languages
• Type-safe translation functions
• Date and time formatting support
• Easy integration with existing projects

Current Language Support

As of now, Tarjem supports code generation for:

• Go

Upcoming Language Support

We're actively working on expanding Tarjem's capabilities. In the near future, we plan to add support for:

• JavaScript
• Python
• Dart
• C
• C++
• Rust
• Zig

Stay tuned for updates!

Installation

To install Tarjem, use the following command:

go install github.com/zakaria-chahboun/tarjem@latest

Or you can directly download the latest version for each OS from the releases page.

Usage

Initializing Translations

To create a new translations.yaml file:

tarjem init

Use the --force flag to overwrite an existing file:

tarjem init --force

Exporting Translations

To generate code from your translations:

tarjem export --lang go

Optionally, specify a package name (for Go):

tarjem export --lang go --package mypackage

Tarjem provides clear error messages for various issues during translation, example:

Clearing Generated Files

To remove the generated translation file:

tarjem clear

Translation File Format

The translations.yaml file should follow this structure:

welcome:
  translations:
    english: "Welcome!"
    arabic: "أهلاً وسهلاً!"

order_status:
  variables:
    order_id: string
    delivery_time: datetime
  translations:
    english: "Your order {order_id} was placed on {delivery_time}."
    arabic: "تم تقديم طلبك {order_id} في {delivery_time}."

Generated Code Usage (Go Example)

After exporting, you can use the generated functions in your Go code:

import (
	"fmt"
	"time"
	"yourproject/tarjem"
)

func main() {

	// Set Arabic as language
	tarjem.SetCurrentLang(tarjem.LangArabic)
    
	// Print the translations
	fmt.Println(tarjem.Welcome()) // Output: أهلاً وسهلاً!
	fmt.Println(tarjem.OrderStatus("12345", time.Now())) // Output: تم تقديم طلبك 12345 في 2024-08-25 14:45:00.

	// Set English as language
	tarjem.SetCurrentLang(tarjem.LangEnglish)

	// Print the translations 
	fmt.Println(tarjem.Welcome()) // Output: Welcome!
	fmt.Println(tarjem.OrderStatus("12345", time.Now())) // Output: Your order 12345 was placed on 2024-08-25 14:45:00.
}

Supported Variable Types

• string
• int
• float
• date
• time
• datetime

Language Field Consistency in Translations

When defining translation fields, you have flexibility in naming the language keys. You can use any format you prefer:

# Option 1
welcome:
  translations:
    arabic: "أهلاً وسهلاً!"
    english: "Welcome!"

# Option 2
welcome:
  translations:
    ar: "أهلاً وسهلاً!"
    en: "Welcome!"

# Option 3
welcome:
  translations:
    lang1: "أهلاً وسهلاً!"
    lang2: "Welcome!"

Important

However, the language keys must be consistent across all translation entries.
