Basic Usage

using System;
using System.Threading.Tasks;
using Lara.Sdk;

class Program
{
    static async Task Main(string[] args)
    {

🔧 API Reference

Core Components

🔐 Authentication

The SDK supports authentication via access key and secret:

var credentials = new Credentials("your-access-key-id", "your-access-key-secret");
var lara = new Translator(credentials);

Environment Variables (Recommended):

export LARA_ACCESS_KEY_ID="your-access-key-id"
export LARA_ACCESS_KEY_SECRET="your-access-key-secret"

var credentials = new Credentials(
    Environment.GetEnvironmentVariable("LARA_ACCESS_KEY_ID"),
    Environment.GetEnvironmentVariable("LARA_ACCESS_KEY_SECRET")
);

🌍 Translator

// Create translator with credentials
var lara = new Translator(credentials);

Text Translation

// Basic translation
var result = await lara.Translate("Hello", "en-US", "fr-FR");

// Multiple strings
var result = await lara.Translate(new[] {"Hello", "World"}, "en-US", "fr-FR");

// TextBlocks (mixed translatable/non-translatable content)
var textBlocks = new List<TextBlock>
{
    new TextBlock("Translatable text", true),
    new TextBlock("<br>", false),  // Non-translatable HTML
    new TextBlock("More translatable text", true),
};
var result = await lara.Translate(textBlocks, "en-US", "fr-FR");

// With advanced options  
var options = new TranslateOptions
{
    Instructions = new[] {"Formal tone"},
    AdaptTo = new[] {"mem_1A2b3C4d5E6f7G8h9I0jKl"},  // Replace with actual memory IDs
    Glossaries = new[] {"gls_1A2b3C4d5E6f7G8h9I0jKl"},  // Replace with actual glossary IDs
    Style = TranslationStyle.Fluid,
    TimeoutInMillis = 10000
};

var result = await lara.Translate("Hello", "en-US", "fr-FR", options);

📖 Document Translation

Simple document translation

var filePath = "/path/to/your/document.txt";  // Replace with actual file path
var fileStream = await lara.Documents.Translate(filePath, "en-US", "fr-FR");

// With options
var options = new DocumentTranslateOptions
{
    AdaptTo = new[] {"mem_1A2b3C4d5E6f7G8h9I0jKl"},  // Replace with actual memory IDs
    Glossaries = new[] {"gls_1A2b3C4d5E6f7G8h9I0jKl"}  // Replace with actual glossary IDs
};

var fileStream = await lara.Documents.Translate(filePath, "en-US", "fr-FR", options);

Document translation with status monitoring

Document upload

//Optional: upload options
var uploadOptions = new DocumentUploadOptions
{
    AdaptTo = new[] {"mem_1A2b3C4d5E6f7G8h9I0jKl"},  // Replace with actual memory IDs
    Glossaries = new[] {"gls_1A2b3C4d5E6f7G8h9I0jKl"}  // Replace with actual glossary IDs
};

var document = await lara.Documents.Upload(filePath, "en-US", "fr-FR", uploadOptions);

Document translation status monitoring

var status = await lara.Documents.Status(document.Id);

Download translated document

var downloadOptions = new DocumentDownloadOptions();

var fileStream = await lara.Documents.Download(document.Id, downloadOptions);

🧠 Memory Management

// Create memory
var memory = await lara.Memories.Create("MyMemory");

// Create memory with external ID (MyMemory integration)
var memory = await lara.Memories.Create("Memory from MyMemory", "aabb1122");  // Replace with actual external ID

// Important: To update/overwrite a translation unit you must provide a tuid. Calls without a tuid always create a new unit and will not update existing entries.
// Add translation to single memory
var memoryImport = await lara.Memories.AddTranslation("mem_1A2b3C4d5E6f7G8h9I0jKl", "en-US", "fr-FR", "Hello", "Bonjour", "greeting_001");

// Add translation to multiple memories
var memoryIds = new List<string> {"mem_1A2b3C4d5E6f7G8h9I0jKl", "mem_2XyZ9AbC8dEf7GhI6jKlMn"};  // Replace with actual memory IDs
var memoryImport = await lara.Memories.AddTranslation(memoryIds, "en-US", "fr-FR", "Hello", "Bonjour", "greeting_002");

// Add with context
var memoryImport = await lara.Memories.AddTranslation(
    "mem_1A2b3C4d5E6f7G8h9I0jKl", "en-US", "fr-FR", "Hello", "Bonjour", "tuid", 
    "sentenceBefore", "sentenceAfter"
);

// TMX import from file
var tmxFilePath = "/path/to/your/memory.tmx";  // Replace with actual TMX file path
var memoryImport = await lara.Memories.ImportTmx("mem_1A2b3C4d5E6f7G8h9I0jKl", tmxFilePath);

// Delete translation
// Important: if you omit tuid, all entries that match the provided fields will be removed
var deleteJob = await lara.Memories.DeleteTranslation(
    "mem_1A2b3C4d5E6f7G8h9I0jKl", "en-US", "fr-FR", "Hello", "Bonjour", "greeting_001"
);

// Wait for import completion
var completedImport = await lara.Memories.WaitForImport(memoryImport, progressCallback, TimeSpan.FromMinutes(5));

📚 Glossary Management

// Create glossary
var glossary = await lara.Glossaries.Create("MyGlossary");

// Import CSV from file
var csvFilePath = "/path/to/your/glossary.csv";  // Replace with actual CSV file path
var glossaryImport = await lara.Glossaries.ImportCsv("gls_1A2b3C4d5E6f7G8h9I0jKl", csvFilePath);

// Check import status
var importStatus = await lara.Glossaries.GetImportStatus(glossaryImport.Id);

// Wait for import completion
var completedImport = await lara.Glossaries.WaitForImport(glossaryImport, progressCallback, TimeSpan.FromMinutes(5));

// Export glossary
var csvData = await lara.Glossaries.Export("gls_1A2b3C4d5E6f7G8h9I0jKl", "csv/table-uni", "en-US");

// Get glossary terms count
var counts = await lara.Glossaries.Counts("gls_1A2b3C4d5E6f7G8h9I0jKl");

Translation Options

public class TranslateOptions
{
    public string[] AdaptTo { get; set; }             // Memory IDs to adapt to
    public string[] Glossaries { get; set; }          // Glossary IDs to use
    public string[] Instructions { get; set; }        // Translation instructions
    public TranslationStyle Style { get; set; }       // Translation style (Fluid, Faithful, Creative)
    public string ContentType { get; set; }           // Content type (text/plain, text/html, etc.)
    public bool? Multiline { get; set; }              // Enable multiline translation
    public int? TimeoutInMillis { get; set; }         // Request timeout in milliseconds
    public string SourceHint { get; set; }            // Hint for source language detection
    public bool? NoTrace { get; set; }                // Disable request tracing
    public bool? Verbose { get; set; }                // Enable verbose response
    public TranslatePriority Priority { get; set; }   // Translation priority
}

Language Codes

The SDK supports full language codes (e.g., en-US, fr-FR, es-ES) as well as simple codes (e.g., en, fr, es):

// Full language codes (recommended)
var result = await lara.Translate("Hello", "en-US", "fr-FR");

// Simple language codes
var result = await lara.Translate("Hello", "en", "fr");

🌐 Supported Languages

The SDK supports all languages available in the Lara API. Use the Languages() method to get the current list:

var languages = await lara.Languages();
Console.WriteLine($"Supported languages: [{string.Join(", ", languages)}]");

⚙️ Configuration

Error Handling

The SDK provides detailed error information:

try
{
    var result = await lara.Translate("Hello", "en-US", "fr-FR");
    Console.WriteLine($"Translation: {result.Translation}");
}
catch (LaraException e)
{
    Console.WriteLine($"API Error: {e.Message}");
}
catch (LaraTimeoutException e)
{
    Console.WriteLine($"Timeout Error: {e.Message}");
}
