Documentation Updates

File: Documentation/app/docs/oop/page.tsx

Content:

Comprehensive getter/setter documentation
Static properties with examples
Private fields convention
Real-world examples: Temperature converter, Product with tax
Best practices section
Feature summary with use cases

Architecture Notes

Getters: Zero-parameter functions stored in Class.Getters map, invoked automatically on property access
Setters: Single-parameter functions stored in Class.Setters map, invoked automatically on property assignment
Static Properties: Stored in Class.StaticProperties map, accessed via Class object member access
Private Fields: Stored in Instance.PrivateFields map, identified by _ prefix convention
Evaluation Order: When accessing property: getters → regular properties → methods
Assignment Order: When assigning property: setters → private fields (if _ prefix) → normal properties

Performance Considerations

Getters computed on every access (no caching) - keep logic lightweight
Setters execute on every assignment - validate efficiently
Static properties shared across instances - single memory allocation
Private fields use separate map - no performance impact on normal properties

Phase 11 Summary:

4 major OOP features implemented
13 comprehensive tests (all passing)
470 total tests passing
Full VS Code extension support with syntax highlighting and snippets
Complete documentation with real-world examples
Compatible with existing OOP features (inheritance, methods, constructors)

Status: Phase 11 Complete ✅

Phase 12: File System Enhancements (v7.0.15)

Goal: Add comprehensive file system operations including append, delete, copy, and file watching capabilities for complete file management.

File Operations (6 functions)

1. file_jog() - Append to File (জোগ = add)

file_jog(path, content)

Parameters:
- path (string) - File path
- content (string) - Content to append
Returns: boolean (success/failure)
Creates file if doesn't exist

Example:

// Append to log file
file_jog("app.log", "2026-02-22 12:00:00 - User logged in\n");
file_jog("app.log", "2026-02-22 12:00:01 - Data processed\n");

// Incremental data collection
file_jog("results.csv", "John,25,Engineer\n");
file_jog("results.csv", "Sarah,30,Doctor\n");

2. file_mochho() - Delete File (মোছো = erase)

file_mochho(path)

Parameters:
- path (string) - File path to delete
Returns: boolean (success/failure)
Permanently deletes the file

Example:

// Delete temporary file
file_mochho("temp.txt");

// Clean up old logs
file_mochho("old_log.txt");

3. file_nokol() - Copy File (নকল = duplicate)

file_nokol(source, destination)

Parameters:
- source (string) - Source file path
- destination (string) - Destination file path
Returns: boolean (success/failure)
Efficiently copies large files using io.Copy

Example:

// Backup configuration
file_nokol("config.json", "config.backup.json");

// Duplicate data
file_nokol("data.txt", "data_copy.txt");

// Create template copy
file_nokol("template.html", "index.html");

4. folder_mochho() - Delete Folder (ফোল্ডার মোছো)

folder_mochho(path, [recursive])

Parameters:
- path (string) - Folder path
- recursive (boolean, optional) - Delete contents recursively
Returns: boolean (success/failure)
If recursive = sotti, deletes folder and all contents
If recursive = mittha/omitted, only deletes empty folder

Example:

// Delete empty folder
folder_mochho("empty_dir");

// Delete folder with contents
folder_mochho("old_project", sotti);

// Clean up build artifacts
folder_mochho("build", sotti);
folder_mochho("dist", sotti);

5. file_dekhun() - Watch File (দেখুন = watch)

file_dekhun(path, callback)

Parameters:
- path (string) - File path to watch
- callback (function) - Function called on change: kaj(event, filename) { ... }
Returns: watcher map with path and active properties
Polls file every 1 second for changes
Callback receives: event ("change"), filename

Example:

// Watch configuration file
dhoro watcher = file_dekhun("config.json", kaj(event, filename) {
  dekho("Config file changed:", event, filename);
  
  // Reload configuration
  dhoro newConfig = json_poro(poro("config.json"));
  dekho("Reloaded:", newConfig);
});

// Watch data file for updates
dhoro dataWatcher = file_dekhun("data.txt", kaj(event, filename) {
  dekho("Data updated at:", somoy());
});

6. file_dekhun_bondho() - Stop Watching (দেখুন বন্ধ = stop watching)

file_dekhun_bondho(watcher)

Parameters:
- watcher (map) - Watcher object returned by file_dekhun()
Returns: boolean (success/failure)
Stops the file watching goroutine

Example:

// Watch file temporarily
dhoro watcher = file_dekhun("temp.log", kaj(event, filename) {
  dekho("Log changed");
});

// Stop watching after 10 seconds
ghumaao(10000).tarpor(kaj() {
  file_dekhun_bondho(watcher);
  dekho("Stopped watching");
});

Real-World Use Cases

Use Case 1: Log File Management

// Initialize log file
lekho("app.log", "Application started at " + somoy() + "\n");

// Append logs throughout runtime
file_jog("app.log", "User login: admin\n");
file_jog("app.log", "Query executed: SELECT * FROM users\n");
file_jog("app.log", "Response sent: 200 OK\n");

// Backup old logs
file_nokol("app.log", "app_" + somoy() + ".log.backup");

// Clear current log
lekho("app.log", "New session started\n");

Use Case 2: Data Pipeline with File Watching

// Watch input directory for new files
dhoro inputWatcher = file_dekhun("input/data.csv", kaj(event, filename) {
  dekho("New data file detected:", filename);
  
  // Read and process data
  dhoro data = poro("input/data.csv");
  dhoro processed = processData(data);
  
  // Write to output
  lekho("output/processed.csv", processed);
  
  // Backup input file
  file_nokol("input/data.csv", "archive/data_" + somoy() + ".csv");
  
  // Clean up input
  file_mochho("input/data.csv");
});

// Clean up on exit
file_dekhun_bondho(inputWatcher);

Use Case 3: Configuration Hot Reload

// Load initial configuration
dhoro config = json_poro(poro("config.json"));

// Watch for configuration changes
dhoro configWatcher = file_dekhun("config.json", kaj(event, filename) {
  dekho("Configuration changed, reloading...");
  
  // Backup old config before reload
  file_nokol("config.json", "config.backup.json");
  
  // Reload configuration
  chesta {
    config = json_poro(poro("config.json"));
    dekho("Configuration reloaded successfully");
  } dhoro_bhul(err) {
    dekho("Failed to reload config:", err);
    // Restore from backup
    file_nokol("config.backup.json", "config.json");
  }
});

Use Case 4: Temporary File Management

// Create temporary directory
folder_banao("temp_processing");

// Process files
ghuriye (dhoro i = 0; i < 10; i = i + 1) {
  dhoro filename = "temp_processing/file_" + lipi(i) + ".txt";
  lekho(filename, "Processing data " + lipi(i));
  // ... process ...
}

// Clean up all temporary files
folder_mochho("temp_processing", sotti);
dekho("Cleaned up temporary files");

Technical Details

File Append (file_jog):

Uses os.OpenFile with O_APPEND|O_CREATE|O_WRONLY flags
Mode 0644 (rw-r--r--)
Creates file if doesn't exist
Efficient for incremental writes (logs, data collection)

File Delete (file_mochho):

Uses os.Remove to delete single file
Returns error if file doesn't exist
Permanent deletion (no recovery)

File Copy (file_nokol):

Uses io.Copy for efficient copying
Handles large files efficiently (streaming copy)
Proper resource cleanup with defer Close()
Creates destination if doesn't exist

Folder Delete (folder_mochho):

Recursive = sotti: uses os.RemoveAll (deletes all contents)
Recursive = mittha: uses os.Remove (only empty folder)
Returns error if folder doesn't exist or not empty (non-recursive)

File Watching (file_dekhun):

Polling-based: checks file ModTime every 1 second
Runs in goroutine (non-blocking)
Callback invoked with ("change", filename) on modification
Returns watcher map: { path: string, active: boolean }
Stops automatically if file is deleted

Stop Watching (file_dekhun_bondho):

Sets watcher active flag to false
Goroutine exits on next iteration
Safe to call multiple times

Performance Notes

File append is optimized for sequential writes (no seek operations)
File copy uses buffered I/O (efficient for large files)
File watching uses 1-second polling (low CPU overhead)
Folder delete (recursive) handles deep directory trees efficiently

Error Handling

All functions return boolean (sotti/mittha) for success/failure:

// Check if operation succeeded
jodi (file_mochho("file.txt")) {
  dekho("File deleted successfully");
} nahole {
  dekho("Failed to delete file");
}

// Safe file copy with error handling
jodi (file_nokol("source.txt", "dest.txt")) {
  dekho("File copied");
} nahole {
  dekho("Copy failed - check if source exists");
}

Phase 12 Summary:

✅ 6 file operation functions implemented
✅ 10 comprehensive tests (all passing)
✅ Append, delete, copy, folder delete, file watching
✅ Efficient I/O operations (io.Copy, goroutines)
✅ Cross-platform file operations
✅ VS Code extension updated (6 functions, 6 snippets)
✅ Documentation updated with 4 real-world examples

Version: 7.0.15
Status: Phase 12 Complete ✅

Phase 13: Error Handling Enhancements (v7.0.16)

Goal: Implement JavaScript-compatible error types (TypeError, ReferenceError, RangeError, SyntaxError) with stack traces and error utility functions for robust error handling.

Custom Error Types (5 error constructors)

BanglaCode now provides standard JavaScript error types as constructors that return error objects:

1. Error() - Generic Error Constructor

Error(message)

Parameters: message (string) - Error description
Returns: Error map with name, message, and stack properties
Use case: General purpose errors

Example:

dhoro err = Error("Something went wrong");
felo err;

// In catch block:
chesta {
    felo Error("Operation failed");
} dhoro_bhul(e) {
    dekho(bhul_naam(e));     // "Error"
    dekho(bhul_message(e));  // "Operation failed"
}

2. TypeError() - Type Mismatch Errors

TypeError(message)

Use case: When wrong type is provided
Returns: Error map with name: "TypeError"

Example:

kaj divide(a, b) {
    jodi (dhoron(a) != "NUMBER" ba dhoron(b) != "NUMBER") {
        felo TypeError("Arguments must be numbers");
    }
    ferao a / b;
}

chesta {
    divide("10", 2);
} dhoro_bhul(e) {
    dekho(bhul_naam(e));  // "TypeError"
}

3. ReferenceError() - Undefined Variable Errors

ReferenceError(message)

Use case: When required variable/property doesn't exist
Returns: Error map with name: "ReferenceError"

Example:

kaj getUser(userId) {
    dhoro users = {"1": "Rahim", "2": "Karim"};
    
    dhoro userKeys = chabi(users);
    dhoro found = mittha;
    ghuriye (dhoro i = 0; i < kato(userKeys); i = i + 1) {
        jodi (userKeys[i] == userId) {
            found = sotti;
        }
    }
    
    jodi (!found) {
        felo ReferenceError("User not found: " + userId);
    }
    
    ferao users[userId];
}

4. RangeError() - Out of Range Errors

RangeError(message)

Use case: When value is outside acceptable range
Returns: Error map with name: "RangeError"

Example:

kaj validateAge(age) {
    jodi (age < 0) {
        felo RangeError("Age cannot be negative");
    }
    jodi (age > 150) {
        felo RangeError("Age must be <= 150");
    }
    ferao sotti;
}

chesta {
    validateAge(-5);
} dhoro_bhul(e) {
    dekho(bhul_naam(e));     // "RangeError"
    dekho(bhul_message(e));  // "Age cannot be negative"
}

5. SyntaxError() - Syntax/Parse Errors

SyntaxError(message)

Use case: When parsing or syntax validation fails
Returns: Error map with name: "SyntaxError"

Example:

kaj parseJSON(jsonString) {
    chesta {
        ferao json_poro(jsonString);
    } dhoro_bhul(e) {
        felo SyntaxError("Invalid JSON format");
    }
}

chesta {
    parseJSON("{invalid json");
} dhoro_bhul(e) {
    dekho(bhul_naam(e));  // "SyntaxError"
}

Error Utility Functions (4 functions)

1. bhul_message(error) - Get Error Message (বুল = error, message)

bhul_message(error)

Parameters: error - Error object
Returns: String containing error message
Works with: Error objects, Exception objects, any object with message property

Example:

dhoro err = TypeError("Expected number");
dekho(bhul_message(err));  // "Expected number"

2. bhul_naam(error) - Get Error Name/Type (নাম = name)

bhul_naam(error)

Parameters: error - Error object
Returns: String containing error type name
Returns: "Error", "TypeError", "ReferenceError", "RangeError", or "SyntaxError"

Example:

dhoro err1 = TypeError("test");
dhoro err2 = RangeError("test");
dekho(bhul_naam(err1));  // "TypeError"
dekho(bhul_naam(err2));  // "RangeError"

3. bhul_stack(error) - Get Stack Trace (স্ট্যাক = stack)

bhul_stack(error)

Parameters: error - Error object
Returns: String containing stack trace information
Shows: Function call chain and line numbers

Example:

chesta {
    felo Error("Test error");
} dhoro_bhul(e) {
    dekho(bhul_stack(e));
    // Stack trace:
    //   at <throw statement> (line X)
}

4. is_error(value) - Check if Value is Error

is_error(value)

Parameters: value - Any value to check
Returns: Boolean (sotti/mittha)
Recognizes: All error types (Error, TypeError, etc.)

Example:

dhoro err = TypeError("test");
dhoro num = 42;

dekho(is_error(err));  // sotti
dekho(is_error(num));  // mittha

Real-World Use Cases

Use Case 1: API Input Validation

kaj validateAPIRequest(request) {
    // Type checking
    jodi (dhoron(request) != "MAP") {
        felo TypeError("Request must be an object");
    }
    
    // Required fields
    dhoro keys = chabi(request);
    dhoro hasMethod = mittha;
    dhoro hasUrl = mittha;
    
    ghuriye (dhoro i = 0; i < kato(keys); i = i + 1) {
        jodi (keys[i] == "method") { hasMethod = sotti; }
        jodi (keys[i] == "url") { hasUrl = sotti; }
    }
    
    jodi (!hasMethod) {
        felo ReferenceError("Missing required field: method");
    }
    jodi (!hasUrl) {
        felo ReferenceError("Missing required field: url");
    }
    
    // Value validation
    dhoro method = request["method"];
    dhoro validMethods = ["GET", "POST", "PUT", "DELETE"];
    dhoro isValidMethod = mittha;
    
    ghuriye (dhoro i = 0; i < kato(validMethods); i = i + 1) {
        jodi (method == validMethods[i]) {
            isValidMethod = sotti;
        }
    }
    
    jodi (!isValidMethod) {
        felo RangeError("Invalid HTTP method: " + method);
    }
    
    ferao sotti;
}

// Usage
chesta {
    validateAPIRequest({"method": "GET", "url": "/api/users"});
    dekho("Request is valid");
} dhoro_bhul(e) {
    dekho("Validation error:");
    dekho("  Type:", bhul_naam(e));
    dekho("  Message:", bhul_message(e));
}

Use Case 2: Safe Data Processing

kaj processUserData(data) {
    // Step 1: Type validation
    chesta {
        jodi (dhoron(data) != "ARRAY") {
            felo TypeError("Data must be an array");
        }
    } dhoro_bhul(e) {
        dekho("Type Error:", bhul_message(e));
        ferao khali;
    }
    
    // Step 2: Range validation
    chesta {
        jodi (kato(data) == 0) {
            felo RangeError("Data array cannot be empty");
        }
        jodi (kato(data) > 1000) {
            felo RangeError("Data array too large (max 1000)");
        }
    } dhoro_bhul(e) {
        dekho("Range Error:", bhul_message(e));
        ferao khali;
    }
    
    // Step 3: Process data
    dhoro processed = [];
    ghuriye (dhoro i = 0; i < kato(data); i = i + 1) {
        chesta {
            dhoro item = data[i];
            jodi (dhoron(item) != "NUMBER") {
                felo TypeError("Array item must be number");
            }
            dhokao(processed, item * 2);
        } dhoro_bhul(e) {
            dekho("Skipping invalid item at index", i, ":", bhul_message(e));
        }
    }
    
    ferao processed;
}

// Usage
dhoro result = processUserData([1, 2, 3, 4, 5]);
dekho(result);  // [2, 4, 6, 8, 10]

Use Case 3: Error Type Discrimination

kaj handleError(error) {
    jodi (!is_error(error)) {
        dekho("Not an error object");
        ferao;
    }
    
    dhoro errorType = bhul_naam(error);
    dhoro errorMsg = bhul_message(error);
    
    // Different handling based on error type
    jodi (errorType == "TypeError") {
        dekho("Type Error - Check data types:");
        dekho("  →", errorMsg);
    } nahole jodi (errorType == "ReferenceError") {
        dekho("Reference Error - Check if variable/property exists:");
        dekho("  →", errorMsg);
    } nahole jodi (errorType == "RangeError") {
        dekho("Range Error - Check value is within bounds:");
        dekho("  →", errorMsg);
    } nahole jodi (errorType == "SyntaxError") {
        dekho("Syntax Error - Check input format:");
        dekho("  →", errorMsg);
    } nahole {
        dekho("Generic Error:");
        dekho("  →", errorMsg);
    }
}

// Test different error types
handleError(TypeError("Expected string"));
handleError(RangeError("Index out of bounds"));
handleError(ReferenceError("Variable undefined"));

Use Case 4: Nested Function Error Propagation

kaj readConfig() {
    dhoro config = poro("config.json");
    jodi (config == khali) {
        felo ReferenceError("Config file not found");
    }
    ferao config;
}

kaj parseConfig() {
    dhoro content = readConfig();  // May throw ReferenceError
    dhoro parsed = json_poro(content);
    jodi (parsed == khali) {
        felo SyntaxError("Invalid config format");
    }
    ferao parsed;
}

kaj validateConfig(config) {
    dhoro keys = chabi(config);
    dhoro hasPort = mittha;
    
    ghuriye (dhoro i = 0; i < kato(keys); i = i + 1) {
        jodi (keys[i] == "port") { hasPort = sotti; }
    }
    
    jodi (!hasPort) {
        felo ReferenceError("Config missing 'port' field");
    }
    
    dhoro port = config["port"];
    jodi (port < 1024 ba port > 65535) {
        felo RangeError("Port must be between 1024 and 65535");
    }
}

kaj loadConfig() {
    chesta {
        dhoro config = parseConfig();
        validateConfig(config);
        ferao config;
    } dhoro_bhul(e) {
        dekho("Failed to load config:");
        dekho("  Error:", bhul_naam(e));
        dekho("  Reason:", bhul_message(e));
        dekho("  Stack:", bhul_stack(e));
        ferao khali;
    }
}

Technical Details

Error Object Structure:

Error objects are Maps with three properties:
- name (string): Error type ("Error", "TypeError", etc.)
- message (string): Error description
- stack (string): Stack trace (populated when thrown)

Stack Trace:

Captured when error is thrown via felo
Shows function name, file, line, and column
Format: at <function> (file:line:col)

Error Propagation:

Errors propagate up call stack until caught
Uncaught errors terminate program execution
Exception object wraps error for internal handling

Try-Catch Integration:

Caught error parameter receives error object (not just message)
Error utilities work with caught errors
Stack trace preserved through catch chain

Performance Notes

Error creation is lightweight (Map allocation)
Stack trace capture is minimal overhead
Error utilities are O(1) map/property access
No performance impact on non-error code paths

Best Practices

Use specific error types:

// ✅ Good - specific error type
felo TypeError("Expected number");

// ❌ Bad - generic error
felo Error("Wrong type");

Provide descriptive messages:

// ✅ Good - actionable message
felo RangeError("Age must be between 0 and 150, got -5");

// ❌ Bad - vague message
felo RangeError("Bad value");

Check error types in handlers:

chesta {
    processData(input);
} dhoro_bhul(e) {
    dhoro errorType = bhul_naam(e);
    jodi (errorType == "TypeError") {
        // Type-specific recovery
    }
}

Validate before processing:

kaj processValue(val) {
    // Validate first
    jodi (dhoron(val) != "NUMBER") {
        felo TypeError("Value must be number");
    }
    jodi (val < 0) {
        felo RangeError("Value must be >= 0");
    }
    
    // Then process
    ferao val * 2;
}

File Operations (6 functions)

1. file_jog() - Append to File (জোগ = add)

2. file_mochho() - Delete File (মোছো = erase)

3. file_nokol() - Copy File (নকল = duplicate)
