Function getSourceSegment

AST inspection and construction utilities.

ast — factory object for building AST nodes by hand.
getDocstring — extract a function/class/module's docstring.
getSourceSegment — slice the original source text for a node.
isASTNode — type guard for AST node values.
iterFields / iterChildNodes — iterate a node's fields or direct child nodes.

getSourceSegment(
    source: string,
    node: ASTNodeUnion,
    options?: { padded?: boolean },
): string | null
Get source segment from source code using node location info.

Slices source using the node's lineno/col_offset/end_lineno/ end_col_offset attributes, matching CPython's ast.get_source_segment.
Parameters
- source: string
  The original source code the node was parsed from
- node: ASTNodeUnion
  The AST node whose corresponding source text should be extracted
- options: { padded?: boolean } = {}
  - Optionalpadded?: boolean
    
    When true, pad the first line with leading spaces so its column offsets line up with the original source (default: false)
Returns string | null
The extracted source text, or null if the node lacks complete location information
