Singularity Enhancement Implementation Session

Date: October 24, 2025
Session: Phase 5 & 7 Implementation
Status: ✅ PARTIAL COMPLETE (Foundation Ready)

🎯 Session Objectives

Implement comprehensive block configuration system and export/import functionality to make Singularity blocks fully configurable and shareable.

✅ Completed Work

Phase 5: Block Configuration System (Partial)

✅ Phase 5.1: Enhanced Block Data Model (COMPLETE)

File Modified: libs/singularity-lib/src/lib/types/logic-builder.types.ts

Added config property to LogicBlock interface with comprehensive structure:

config?: {
  inputs?: {
    [inputName: string]: {
      type: 'variable' | 'constant' | 'connection';
      value?: any;
      variableName?: string;
      connectionId?: string;
      defaultValue?: any;
    };
  };
  outputs?: {
    [outputName: string]: {
      variableName?: string;
    };
  };
  settings?: {
    operation?: string;
    [key: string]: any;
  };
  ui?: {
    color?: string;
    icon?: string;
    collapsed?: boolean;
  };
};

Key Benefits:

• Blocks now have structured configuration
• Everything stored as JSON
• Backward compatible (config is optional)

✅ Phase 5.4: Execution Engine Config Support (COMPLETE)

File Modified: libs/singularity-lib/src/lib/services/logic-execution-engine.service.ts

New Methods Added:

1. resolveInputsFromConfig() (~40 lines)

   • Resolves inputs from block.config
   • Supports: constant values, variable references ($var), port connections
   • Returns Record<string, any> with resolved values

2. storeOutputsFromConfig() (~15 lines)

   • Stores execution results in configured output variables
   • Maps outputs to user-named variables in execution context

3. Updated executeFunctionBlock() (~30 lines)

   • Checks for block.config first
   • Falls back to block.properties if no config
   • Uses resolved inputs
   • Stores results in configured outputs

4. Updated executeActionBlock() (~60 lines)

   • Reads operation from config.settings
   • Resolves inputs from config
   • Merges into properties for existing handlers
   • Stores outputs after execution

Execution Flow with Config:

1. Block has config? → YES
2. Resolve inputs from config:
   - Variable: Read from context.variables
   - Constant: Use value directly
   - Connection: Read from connected block output
3. Get operation from config.settings
4. Execute block logic with resolved inputs
5. Store result in configured output variable

Example Logs:

📝 [Config] Input "a" = 5 (from variable: inputA)
📝 [Config] Input "b" = 10 (constant)
🔧 [Function] Using block.config for inputs
🧮 [Calculate] 5 + 10 = 15
💾 [Config] Output "result" stored in variable: total = 15

Phase 7: Export/Import System (COMPLETE)

✅ Phase 7.1: Export Flow Interface (COMPLETE)

New File: libs/singularity-lib/src/lib/models/exported-flow.interface.ts

Interfaces Created:

1. ExportedFlow - Main export structure

   interface ExportedFlow {
     version: '1.0.0';
     flowId: string;
     flowName: string;
     description: string;
     author: string;
     created: string;
     modified: string;
     blocks: LogicBlock[];  // With block.config!
     connections: LogicConnection[];
     requiredVariables: string[];
     outputVariables: string[];
     dependencies: string[];
     canvasState: { zoom, panX, panY };
   }
   

2. FlowExportOptions - Export configuration

3. FlowImportOptions - Import configuration

4. FlowImportResult - Import result status

✅ Phase 7.2: Flow Export Service (COMPLETE)

New File: libs/singularity-lib/src/lib/services/flow-export.service.ts

Public Methods:

1. exportFlow(flowId, options)

   • Loads flow from storage
   • Extracts required/output variables
   • Identifies dependencies

   • Sanitizes filename

3. copyToClipboard(exportedFlow, options)

   • Copies JSON to clipboard
   • Supports minified or pretty-printed

4. generateShareURL(exportedFlow)

   • Base64 encodes flow
   • Generates shareable URL
   • Copies to clipboard

Private Helper Methods:

• extractRequiredVariables() - Finds all variable-type inputs
• extractOutputVariables() - Finds all output variable names
• extractDependencies() - Identifies external dependencies
• sanitizeFileName() - Cleans filename for download

✅ Phase 7.3: Flow Import Service (COMPLETE)

New File: libs/singularity-lib/src/lib/services/flow-import.service.ts

Public Methods:

1. importFromFile(file, options)

   • Reads file as text

Private Methods:

1. importFlow(exportedFlow, options)

   • Validates schema
   • Handles import modes (replace/merge/new)
   • Resolves ID conflicts
   • Saves to storage
   • Returns FlowImportResult

2. validateExportedFlow(exportedFlow)

• Tabs: Inputs, Outputs, Settings, Appearance
• Input type selector (variable/constant/connection)
• Output variable naming
• Operation selector
• Color picker
• Save → updates block.config

Inline Quick Config:

• Operation buttons (add/subtract/multiply)
• Inline input editors
• Live result preview
• Click to expand full modal

Phase 6: AI Integration (Can Start in Parallel)

AI Block Assistant:

• Uses lib-simple-ai-chat from @gograb-ai
• Natural language → block config JSON
• System prompt for config generation

NL to Flow:

• Uses lib-simple-ai-chat from @gograb-ai
• Natural language → complete flow JSON
• System prompt for flow generation

Phase 7.4: UI Buttons (After Phase 5.2)

Logic Builder Header:

• Export button → opens export options modal
• Import button → opens file picker
• Share button → generates and copies URL

📝 Usage Examples

Export Flow

// In Logic Builder component
const exportService = inject(FlowExportService);

async exportCurrentFlow() {
  const flowId = this.currentFlowId();
  const exportedFlow = await exportService.exportFlow(flowId);
  
  // Option 1: Download as file
  exportService.downloadAsJSON(exportedFlow);
  
  // Option 2: Copy to clipboard
  await exportService.copyToClipboard(exportedFlow);
  
  // Option 3: Generate share URL
  const shareUrl = await exportService.generateShareURL(exportedFlow);
  // URL automatically copied to clipboard
}

Import Flow

// In Logic Builder component
const importService = inject(FlowImportService);

async importFlow() {
  // Opens file picker, imports, returns result
  const result = await importService.openFilePicker({
    mode: 'new',  // Creates new flow
    validateSchema: true,
    resolveConflicts: 'rename'
  });
  
  if (result?.success) {
    console.log(`Imported: ${result.flowName}`);
    console.log(`Blocks: ${result.blocksImported}`);
    // Load flow in Logic Builder
    await this.loadFlow(result.flowId);
  }
}

Configure Block

// Block with config
const block: LogicBlock = {
  id: 'calc_001',
  name: 'Add Numbers',
  type: 'function',
  category: 'math',
  config: {
    inputs: {
      a: { 
        type: 'variable', 
        variableName: 'inputA' 
      },
      b: { 
        type: 'constant', 
        value: 10 
      }
    },
    settings: {
      operation: 'add'
    },
    outputs: {
      result: { 
        variableName: 'total' 
      }
    },
    ui: {
      color: '#3B82F6',
      icon: 'plus'
    }
  },
  // ... other required fields
};

// Execution automatically:
// 1. Reads $inputA from context
// 2. Uses constant 10 for b
// 3. Executes add operation
// 4. Stores result in 'total' variable

⚠️ Important Notes

Backward Compatibility

Old blocks (without config) continue to work:

// Old block - still works
const oldBlock: LogicBlock = {
  id: 'old_001',
  type: 'function',
  properties: {
    functionName: 'calculate',
    arguments: { a: 5, b: 10 }
  }
  // No config property
};

Execution engine checks config first:

if (block.config?.inputs) {
  // Use new config system
  args = this.resolveInputsFromConfig(block.config.inputs, context);
} else {
  // Fallback to old properties
  args = block.properties?.['arguments'] || {};
}
