Module extract 

Shared extraction utilities for extract_function (and future inline_symbol).

Provides:

• detect_free_variables — classify identifier references in a byte range
• detect_return_value — infer what the extracted function should return
• generate_extracted_function — produce function text for TS/JS or Python

Structs

FreeVariableResult

Classification result for free variables in a selected byte range.

ScopeConflict

A detected scope conflict when inlining a function body at a call site.

Enums

ReturnKind

What the extracted function should return.

Functions

detect_free_variables

Walk the AST for a byte range and classify every identifier reference.

detect_return_value

Detect what the extracted code range should return.

detect_scope_conflicts

Detect scope conflicts between the call site scope and the function body being inlined.

generate_call_site

Generate the call site text that replaces the extracted range.

generate_extracted_function

Generate the text for an extracted function.

substitute_params

Substitute parameter names with argument expressions in a function body.

validate_single_return

Validate that a function has at most one return statement (suitable for inlining).
