exceptions.py

Custom exceptions for the NodeWeaver package.

This module defines the exception hierarchy used throughout NodeWeaver. All custom exceptions inherit from the base ScriptGeneratorError.

Exception Hierarchy

ScriptGeneratorError ├── ValidationError └── ConfigurationError

ConfigurationError

Bases: ScriptGeneratorError

Raised when configuration loading or parsing fails.

This exception indicates that there was an error loading or parsing configuration files or settings.

Example

try: ... with open(config_path) as f: ... config = json.load(f) ... except json.JSONDecodeError as e: ... raise ConfigurationError(f"Invalid JSON in config: {e}")

Source code in core/exceptions.py

class ConfigurationError(ScriptGeneratorError):
    """Raised when configuration loading or parsing fails.

    This exception indicates that there was an error loading or parsing
    configuration files or settings.

    Example:
        >>> try:
        ...     with open(config_path) as f:
        ...         config = json.load(f)
        ... except json.JSONDecodeError as e:
        ...     raise ConfigurationError(f"Invalid JSON in config: {e}")
    """
    pass

ScriptGeneratorError

Bases: Exception

Base exception for all NodeWeaver script generation errors.

This is the parent class for all custom exceptions in the script generation system. All specific error types should inherit from this class.

Example

try: ... # Script generation code ... except ScriptGeneratorError as e: ... print(f"Script generation failed: {e}")

Source code in core/exceptions.py

class ScriptGeneratorError(Exception):
    """Base exception for all NodeWeaver script generation errors.

    This is the parent class for all custom exceptions in the script generation
    system. All specific error types should inherit from this class.

    Example:
        >>> try:
        ...     # Script generation code
        ... except ScriptGeneratorError as e:
        ...     print(f"Script generation failed: {e}")
    """
    pass

ValidationError

Bases: ScriptGeneratorError

Raised when script validation fails.

This exception indicates that script validation failed due to invalid input, missing required fields, or other validation errors.

Example

if not script_content: ... raise ValidationError("Script content cannot be empty")

Source code in core/exceptions.py

class ValidationError(ScriptGeneratorError):
    """Raised when script validation fails.

    This exception indicates that script validation failed due to invalid input,
    missing required fields, or other validation errors.

    Example:
        >>> if not script_content:
        ...     raise ValidationError("Script content cannot be empty")
    """
