Python Package - -Python implementation of bidirectional conversion between DS syntax formats. - -## Installation - -```bash -pip install -e . -``` - -For development: - -```bash -pip install -e ".[dev]" -``` - -## Usage - -### As a Library - -```python -from ds_bnf import unparse, parse - -# Convert Ds (lisp-like) to Dsp (traditional) -dsp = unparse('(binary -> a b)') -print(dsp) # Output: (a -> b) - -# Convert Dsp (traditional) to Ds (lisp-like) -ds = parse('a -> b') -print(ds) # Output: (binary -> a b) -``` - -### Command-line Interface - -```bash -# Unparse: Ds → Dsp -ds-unparse input.ds > output.dsp -echo "(binary -> a b)" | ds-unparse - -# Parse: Dsp → Ds -ds-parse input.dsp > output.ds -echo "a -> b" | ds-parse -``` - -## Generating Parsers - -Before using the package, you need to generate the ANTLR parsers: - -```bash -# From the bnf/python directory -antlr4 -Dlanguage=Python3 -visitor -o ds_bnf/generated ../grammars/Ds.g4 ../grammars/Dsp.g4 -``` - -Or use the setup script from the bnf directory: - -```bash -cd .. -./setup.sh -``` - -## Testing - -```bash -pytest -``` - -With coverage: - -```bash -pytest --cov=ds_bnf -``` - -## License - -AGPL-3.0-or-later diff --git a/bnf/setup.py b/bnf/setup.py new file mode 100644 index 0000000..cc66cdd --- /dev/null +++ b/bnf/setup.py @@ -0,0 +1,92 @@ +""" +Setup script for apyds-bnf package with ANTLR parser generation +""" + +import os +import subprocess +import sys +from pathlib import Path + +from setuptools import setup +from setuptools.command.build_py import build_py + + +class BuildWithAntlr(build_py): + """Custom build command that generates ANTLR parsers before building""" + + def run(self): + """Generate ANTLR parsers and then run the standard build""" + self.generate_antlr_parsers() + super().run() + + def generate_antlr_parsers(self): + """Generate Python parsers from ANTLR grammars""" + base_dir = Path(__file__).parent + grammars_dir = base_dir / "grammars" + output_dir = base_dir / "apyds_bnf" / "generated" + + # Create output directory + output_dir.mkdir(parents=True, exist_ok=True) + + # Create __init__.py for the generated package + (output_dir / "__init__.py").touch() + + # Generate parsers for both grammars + for grammar in ["Ds.g4", "Dsp.g4"]: + grammar_path = grammars_dir / grammar + if not grammar_path.exists(): + print(f"Warning: Grammar file {grammar_path} not found", file=sys.stderr) + continue + + print(f"Generating parser for {grammar}...") + try: + subprocess.run( + [ + "antlr4", + "-Dlanguage=Python3", + "-visitor", + "-no-listener", + "-o", + str(output_dir), + str(grammar_path), + ], + check=True, + cwd=base_dir, + ) + print(f"Successfully generated parser for {grammar}") + except subprocess.CalledProcessError as e: + print(f"Error generating parser for {grammar}: {e}", file=sys.stderr) + # Try using antlr4-tools if antlr4 command is not available + try: + subprocess.run( + [ + sys.executable, + "-m", + "antlr4_tools", + "-Dlanguage=Python3", + "-visitor", + "-no-listener", + "-o", + str(output_dir), + str(grammar_path), + ], + check=True, + cwd=base_dir, + ) + print(f"Successfully generated parser for {grammar} using antlr4-tools") + except (subprocess.CalledProcessError, FileNotFoundError) as e2: + print( + f"Error: Could not generate parsers.

'->' term` which permits zero terms before the arrow. This design matches the specification from the issue and allows flexibility in rule definition. - -**SYMBOL Token**: The SYMBOL token is defined as `~[ \t\r\n,()]+` which is intentionally permissive to allow a wide variety of symbols. The lexer resolves potential ambiguities through maximal munch rule, token definition order, and keyword precedence. This design maintains compatibility with the DS system's existing symbol naming conventions. - -## Development - -This package follows the mono repo layout and is designed to be self-contained within the `bnf` directory. -
