Dynamic Language.Register()

[kacisse]

Is your feature request related to a problem? Please describe. First of all, amazing work. I think I'm not using the API properly. Here is what I'm doing:

1. Detect language with the language detector --> OK I et a Language object
2. I need to detect sentences optimized for that language --> KO because I need to enter for ex English.Register() before creating the pipeline, but its not ideal I would like to do Language.Register() dynamically because I might have several languages. Currently I have to either register all languages at the beginning of the app, OR create a custom mapping somehow but it's really messy.

Describe the solution you'd like do Language.Register() dynamically

Describe alternatives you've considered Currently I have to either register all languages at the beginning of the app, OR create a custom mapping somehow but it's really messy.

Additional context I'm probably don't use the proper API here, so please let me know if there is a seamless solution :)

Best.

Here is my fix, it works.

private void TryRegisterConcreteLanguage(Language language)
{
    lock (_registerLock)
    {
        var langName = language.ToString(); // "English", "Arabic", etc.
        var typeName = $"Catalyst.Models.{langName}";

        try
        {
            // Step 1: Load the assembly manually if it's not already loaded
            var assembly = AppDomain.CurrentDomain
                .GetAssemblies()
                .FirstOrDefault(a => a.GetName().Name == typeName)
                ?? Assembly.Load(typeName); // Load from name (e.g., "Catalyst.Models.English")

            if (assembly == null)
            {
                _logger.LogWarning("Failed to load assembly: {Assembly}", typeName);
                return;
            }

            // Step 2: Try to find the type
            var langType = assembly.ExportedTypes.FirstOrDefault(t => t?.FullName != null && t.FullName.Equals(typeName));

            if (langType == null)
            {
                _logger.LogWarning("Type {TypeName} not found in assembly {Assembly}", typeName, typeName);
                return;
            }
            // Step 3: Call Register()
            var registerMethod = langType.GetMethod("Register", BindingFlags.Public | BindingFlags.Static);

            if (registerMethod != null)
            {
                registerMethod.Invoke(null, null);
                _logger.LogInformation("Catalyst language registered: {Language}", langName);
            }
            else
            {
                _logger.LogWarning("Register() method not found for type {TypeName}", typeName);
            }
        }
        catch (Exception ex)
        {
            _logger.LogError(ex, "Exception while registering Catalyst language: {Language}", langName);
        }
    }
}
