Example usage: ```python from jsgf import Grammar, DeterministicGenerator, GeneratorConfig grammar = Grammar.from_file("example.jsgf") config = GeneratorConfig(max_recursion_depth=100) generator = DeterministicGenerator(grammar, config) for sentence in generator.generate(): print(sentence) ``` --- jsgf/__init__.py | 19 +++ jsgf/ast_nodes.py | 152 +++++++++++++++++ jsgf/cli.py | 255 ++++++++++++++++++++++++++++ jsgf/exceptions.py | 40 +++++ jsgf/generators.py | 369 +++++++++++++++++++++++++++++++++++++++++ jsgf/grammar.py | 319 +++++++++++++++++++++++++++++++++++ jsgf/legacy_adapter.py | 91 ++++++++++ jsgf/parser.py | 274 ++++++++++++++++++++++++++++++ 8 files changed, 1519 insertions(+) create mode 100644 jsgf/__init__.py create mode 100644 jsgf/ast_nodes.py create mode 100644 jsgf/cli.py create mode 100644 jsgf/exceptions.py create mode 100644 jsgf/generators.py create mode 100644 jsgf/grammar.py create mode 100644 jsgf/legacy_adapter.py create mode 100644 jsgf/parser.py diff --git a/jsgf/__init__.py b/jsgf/__init__.py new file mode 100644 index 0000000..b703eed --- /dev/null +++ b/jsgf/__init__.py @@ -0,0 +1,19 @@ +""" +JSGF Tools - Modern Python library for parsing and generating from JSGF grammars. + +This package provides a clean, object-oriented API for working with JSGF grammars. +""" + +from .grammar import Grammar +from .generators import DeterministicGenerator, ProbabilisticGenerator +from .exceptions import JSGFError, ParseError, GenerationError + +__version__ = "2.0.0" +__all__ = [ + "Grammar", + "DeterministicGenerator", + "ProbabilisticGenerator", + "JSGFError", + "ParseError", + "GenerationError" +] \ No newline at end of file diff --git a/jsgf/ast_nodes.py b/jsgf/ast_nodes.py new file mode 100644 index 0000000..fbeb49a --- /dev/null +++ b/jsgf/ast_nodes.py @@ -0,0 +1,152 @@ +""" +Abstract Syntax Tree nodes for JSGF grammars. + +This module provides the core AST node classes that represent different +parts of a JSGF grammar structure. +""" + +from typing import List, Union, Any, Optional +from abc import ABC, abstractmethod + + +class JSGFNode(ABC): + """Base class for all JSGF AST nodes.""" + + @abstractmethod + def __str__(self) -> str: + """Return a string representation of this node.""" + pass + + def __repr__(self) -> str: + return f"{self.__class__.__name__}({str(self)})" + + +class Terminal(JSGFNode): + """Represents a terminal symbol (token) in the grammar.""" + + def __init__(self, value: str): + self.value = value + + def __str__(self) -> str: + return self.value + + def __eq__(self, other: Any) -> bool: + return isinstance(other, Terminal) and self.value == other.value + + def __hash__(self) -> int: + return hash(self.value) + + +class NonTerminal(JSGFNode): + """Represents a non-terminal symbol in the grammar.""" + + def __init__(self, name: str): + self.name = name + + def __str__(self) -> str: + return self.name + + def __eq__(self, other: Any) -> bool: + return isinstance(other, NonTerminal) and self.name == other.name + + def __hash__(self) -> int: + return hash(self.name) + + +class Sequence(JSGFNode): + """Represents a sequence of elements.""" + + def __init__(self, elements: List[JSGFNode]): + self.elements = elements + + def __str__(self) -> str: + return " ".join(str(element) for element in self.elements) + + def __iter__(self): + return iter(self.elements) + + def __len__(self) -> int: + return len(self.elements) + + def __getitem__(self, index: int) -> JSGFNode: + return self.elements[index] + + +class Alternative(JSGFNode): + """Represents alternatives (choices) in the grammar.""" + + def __init__(self, choices: List[Union[JSGFNode, tuple]]): + """ + Initialize alternatives. + + Args: + choices: List of choices.
