✅ Language-Specific Metadata Generation Refactor

🎯 Problem Solved

Before: The SDK generator used a single generateSDKMetadata() function that returned a JavaScript object, then manually converted it to each language's syntax with inline template literals. This caused:

  • ❌ Syntax errors (e.g., true vs True in Python)
  • ❌ Format issues (e.g., JSON.stringify() in PHP arrays)
  • ❌ Maintenance nightmare (changing metadata required updating 4+ places)
  • ❌ Language-specific quirks handled inconsistently

After: Created dedicated language-specific metadata code generation functions that handle syntax correctly for each language.

🔧 Implementation

New Functions Added

1. generateJavaScriptMetadataCode(sdkMetadata)

Generates TypeScript/JavaScript metadata with proper syntax:

const SDK_METADATA = {
  sdkId: 'uuid',
  sdkName: 'SDK Name',
  // ... proper JS boolean: true/false
  telemetryEnabled: true,
  metadata: { /* proper JSON object */ }
};

export function getSDKMetadata() {
  return { ...SDK_METADATA };
}

2. generatePythonMetadataCode(sdkMetadata)

Generates Python metadata with proper syntax:

SDK_METADATA = {
    "sdk_id": "uuid",
    "sdk_name": "SDK Name",
    # ... proper Python boolean: True/False
    "telemetry_enabled": True,
    "metadata": {
        # proper Python dict
    }
}

def get_sdk_metadata():
    """Returns SDK identification and telemetry metadata"""
    return SDK_METADATA.copy()

3. generateGoMetadataCode(sdkMetadata)

Generates Go metadata with proper syntax:

// SDKMetadata contains SDK identification and telemetry configuration
type SDKMetadata struct {
	SDKID             string            `json:"sdkId"`
	SDKName           string            `json:"sdkName"`
	// ... proper Go boolean: true/false
	TelemetryEnabled  bool              `json:"telemetryEnabled"`
	Metadata          map[string]string `json:"metadata"`
}

func GetSDKMetadata() SDKMetadata {
	return SDKMetadata{
		SDKID:             "uuid",
		SDKName:           "SDK Name",
		// ... proper Go struct initialization
	}
}

4. generatePHPMetadataCode(sdkMetadata)

Generates PHP metadata with proper syntax:

/**
 * SDK Metadata - Identification and telemetry configuration
 */
class SDKMetadata
{
    public static function get(): array
    {
        return [
            'sdkId' => 'uuid',
            'sdkName' => 'SDK Name',
            // ... proper PHP boolean: true/false
            'telemetryEnabled' => true,
            'metadata' => [
                // proper PHP associative array
            ]
        ];
    }
}

5. generateRubyMetadataCode(sdkMetadata)

Generates Ruby metadata with proper syntax:

# SDK Metadata - Identification and telemetry configuration
module SDKMetadata
  def self.get
    {
      sdk_id: 'uuid',
      sdk_name: 'SDK Name',
      # ... proper Ruby boolean: true/false
      telemetry_enabled: true,
      metadata: {
        # proper Ruby hash
      }
    }
  end
end

📊 Before vs After Comparison

JavaScript SDK

Before:

const SDK_METADATA: SDKMetadata = {
  sdkId: "${sdkMetadata.sdkId}",
  sdkName: "${sdkMetadata.sdkName}",
  // ... manual template literal
  telemetryEnabled: ${sdkMetadata.telemetryEnabled},
  metadata: ${JSON.stringify(sdkMetadata.metadata)}
};

After:

${this.generateJavaScriptMetadataCode(sdkMetadata)}

Python SDK

Before:

SDK_METADATA = {
    "sdk_id": "${sdkMetadata.sdkId}",
    "sdk_name": "${sdkMetadata.sdkName}",
    # PROBLEM: JavaScript boolean syntax
    "telemetry_enabled": ${sdkMetadata.telemetryEnabled ? 'True' : 'False'},
    # PROBLEM: JSON.stringify() output
    "metadata": ${JSON.stringify(sdkMetadata.metadata)}
}

After:

${this.generatePythonMetadataCode(sdkMetadata)}

Go SDK

Before:

type SDKMetadata struct {
	SDKID             string            `json:"sdkId"`
	// ... 30+ lines of manual template literals
}

func GetSDKMetadata() SDKMetadata {
	return SDKMetadata{
		SDKID:             "${sdkMetadata.sdkId}",
		// ... manual field assignments
	}
}

After:

${this.generateGoMetadataCode(sdkMetadata)}

PHP SDK

Before:

class SDKMetadata
{
    public static function get(): array
    {
        return [
            'sdkId' => '${sdkMetadata.sdkId}',
            // PROBLEM: JavaScript ternary for boolean
            'telemetryEnabled' => ${sdkMetadata.telemetryEnabled ? 'true' : 'false'},
            // PROBLEM: JSON.stringify() instead of PHP array
            'metadata' => ${JSON.stringify(sdkMetadata.metadata)}
        ];
    }
}

After:

${this.generatePHPMetadataCode(sdkMetadata)}

✅ Benefits

1. Correctness

  • ✅ Each language gets proper syntax automatically
  • ✅ No more boolean conversion issues (true vs True)
  • ✅ No more JSON.stringify() in PHP arrays
  • ✅ Proper data structure formats for each language

2. Maintainability

  • ✅ Single source of truth for each language's metadata format
  • ✅ Changes to metadata structure only need updates in one place per language
  • ✅ Easy to add new languages - just create a new function
  • ✅ Clear separation of concerns

3. Consistency

  • ✅ All SDKs follow the same pattern
  • ✅ Metadata structure is identical across languages (just different syntax)
  • ✅ Easy to verify correctness by comparing function outputs

4. Extensibility

  • ✅ Adding new metadata fields is straightforward
  • ✅ Language-specific customizations are isolated
  • ✅ Can easily add more languages (Rust, Swift, Kotlin, etc.)

🔍 Language-Specific Handling

Booleans

Language Syntax Handled By
JavaScript true / false Direct value
Python True / False Ternary: ${val ? 'True' : 'False'}
Go true / false Direct value
PHP true / false Ternary: ${val ? 'true' : 'false'}
Ruby true / false Direct value

Object/Dict/Map Syntax

Language Syntax Example
JavaScript { key: value } metadata: { generator: "..." }
Python { "key": value } "metadata": { "generator": "..." }
Go map[string]string{ "key": "value" } Metadata: map[string]string{ "generator": "..." }
PHP [ 'key' => 'value' ] 'metadata' => [ 'generator' => '...' ]
Ruby { key: value } metadata: { generator: '...' }

Naming Conventions

Language Convention Example
JavaScript camelCase sdkId, telemetryEnabled
Python snake_case sdk_id, telemetry_enabled
Go PascalCase SDKID, TelemetryEnabled
PHP camelCase sdkId, telemetryEnabled
Ruby snake_case sdk_id, telemetry_enabled

📝 Usage in SDK Generators

Before (Inconsistent)

// In generateJavaScriptSDK()
const metadata = `const SDK_METADATA = { ... }`;

// In generatePythonSDK()
const metadata = `SDK_METADATA = { ... }`;  // Different syntax!

// In generateGoSDK()
const metadata = `type SDKMetadata struct { ... }`;  // Different structure!

After (Consistent)

// In generateJavaScriptSDK()
const sdkMetadata = this.generateSDKMetadata(sdk, "javascript");
const metadataCode = this.generateJavaScriptMetadataCode(sdkMetadata);

// In generatePythonSDK()
const sdkMetadata = this.generateSDKMetadata(sdk, "python");
const metadataCode = this.generatePythonMetadataCode(sdkMetadata);

// In generateGoSDK()
const sdkMetadata = this.generateSDKMetadata(sdk, "go");
const metadataCode = this.generateGoMetadataCode(sdkMetadata);

🚀 Future Enhancements

With this architecture, adding new languages is easy:

// Add Rust support
static generateRustMetadataCode(sdkMetadata) {
  return `pub struct SdkMetadata {
    pub sdk_id: String,
    pub sdk_name: String,
    pub telemetry_enabled: bool,
    // ... proper Rust syntax
  }`;
}

// Add Swift support
static generateSwiftMetadataCode(sdkMetadata) {
  return `struct SDKMetadata {
    let sdkId: String
    let sdkName: String
    let telemetryEnabled: Bool
    // ... proper Swift syntax
  }`;
}

✅ Testing

Verification Checklist

  • ✅ JavaScript SDK generates valid TypeScript
  • ✅ Python SDK generates valid Python (no true, uses True)
  • ✅ Go SDK generates valid Go code
  • ✅ PHP SDK generates valid PHP (no JSON.stringify, uses arrays)
  • ✅ Ruby SDK ready for future implementation
  • ✅ All SDKs have identical metadata structure (just different syntax)
  • ✅ Telemetry clients can access metadata correctly in each language
