code-chunker 1.1.2

A pragmatic multi-language code parser optimized for LLM applications

Code Chunker

A pragmatic multi-language code parser optimized for LLM applications and RAG systems.

Features

• Multi-language support: Python, JavaScript, TypeScript, Solidity, Go, Rust
• Optimized for LLMs: Provides structured output ideal for language models
• Lightweight: Minimal dependencies, fast parsing
• Configurable: Adjust chunk sizes, confidence thresholds, and more
• Easy to use: Simple API with both file and directory parsing

Installation

pip install code-chunker

Quick Start

from code_chunker import CodeChunker

# Initialize the chunker
chunker = CodeChunker()

# Parse a code string
code = """
def hello_world():
    print("Hello, World!")
"""

result = chunker.parse(code, language='python')

# Print the chunks
for chunk in result.chunks:
    print(f"{chunk.type}: {chunk.name}")

# Parse a file
result = chunker.parse_file('example.py')

# Parse a directory
results = chunker.parse_directory('src/')

Configuration

from code_chunker import CodeChunker, ChunkerConfig

config = ChunkerConfig(
    max_chunk_size=2000,
    min_chunk_size=100,
    include_comments=True,
    confidence_threshold=0.8
)

chunker = CodeChunker(config=config)

Supported Languages

• Python (.py)
• JavaScript (.js, .jsx)
• TypeScript (.ts, .tsx)
• Solidity (.sol)
• Go (.go)

API Reference

CodeChunker

The main class for parsing code.

chunker = CodeChunker(config=None)

Methods

• parse(code: str, language: str) -> ParseResult: Parse a code string
• parse_file(file_path: Union[str, Path]) -> ParseResult: Parse a file
• parse_directory(directory: Union[str, Path], recursive: bool = True, extensions: Optional[List[str]] = None) -> List[ParseResult]: Parse a directory

ParseResult

The result of parsing code.

Attributes

• language: str: The programming language
• file_path: Optional[str]: Path to the source file
• chunks: List[CodeChunk]: List of code chunks
• imports: List[Import]: List of imports
• exports: List[str]: List of exports
• raw_code: str: The original code

CodeChunk

Represents a piece of code.

Attributes

• type: ChunkType: The type of chunk (function, class, etc.)
• name: Optional[str]: The name of the chunk
• code: str: The actual code
• start_line: int: Starting line number
• end_line: int: Ending line number
• language: str: Programming language
• confidence: float: Confidence score (0-1)
• metadata: Dict[str, Any]: Additional metadata

Dependencies

• For basic usage: No external dependencies
• For performance analysis: psutil
• For visualization: Modern web browser to view generated HTML
