Config

• arbitrary_types_allowed: bool = True

Fields

• chunk_lines (int)

• chunk_lines_overlap (int)

• language (str)

• max_chars (int)

field chunk_lines: int = 40

The number of lines to include in each chunk.

Constraints

• exclusiveMinimum = 0

field chunk_lines_overlap: int = 15

How many lines of code each chunk overlaps with.

Constraints

• exclusiveMinimum = 0

field language: str [Required]

The programming language of the code being split.

field max_chars: int = 1500

Maximum number of characters per chunk.

Constraints

• exclusiveMinimum = 0

classmethod class_name() → str

Get the class name, used as a unique ID in serialization.

This provides a key that makes serialization robust against actual class name changes.

classmethod from_defaults(language: str, chunk_lines: int = 40, chunk_lines_overlap: int = 15, max_chars: int = 1500, callback_manager: Optional[CallbackManager] = None, parser: Any = None) → CodeSplitter

Create a CodeSplitter with default values.

split_text(text: str) → List[str]

Split incoming code and return chunks using the AST.
