    Function literalEval

    Parser entry points and location-manipulation helpers.

    • parse / parseFile — parse Python source (or a file on disk) into an AST.
    • literalEval — safely evaluate a literal expression node, mirroring ast.literal_eval.
    • fixMissingLocations — fill in missing lineno/col_offset info on a hand-built tree by copying it from parent nodes.
    • copyLocation — copy location info from one node to another.
    • incrementLineno — shift every line number in a tree by an offset.
    • ParseOptions — options accepted by parse.

    • Parses source and evaluates its first expression statement as a Python literal, mirroring CPython's ast.literal_eval. Supports constants, lists, tuples, sets, dicts (no unpacking), and unary/binary +/- on numeric literals.

      Parameters

      • source: string

        Python source containing a single literal expression.

      Returns any

      The evaluated JavaScript value corresponding to the literal.

      If source contains no expression statement, or the expression isn't a supported literal form.
