NAME

std/path/zz/operators - Operator definitions for ZZPath expressions.

IMPLEMENTATION SUPPORT

This module is supported by all implementations of ZuzuScript.

DESCRIPTION

This module extends the base ZPath operator model with ZuzuScript-flavoured expression operators.

EXPORTS

Classes

  • Operator

    ZZPath operator class extending std/path/z/operators Operator.

Functions

  • string_operand(ev, ctx, expr), string_operands(ev, ctx, left, right)

    Parameters: evaluator, context, and expression AST nodes. Returns: String or Array. Evaluates one or two operands as strings.

  • first_eval_value(values), primitive_eval_value(values)

    Parameters: values is an evaluated node array. Returns: value. Extracts the first or primitive value used by ZZPath operators.

  • collection_operand(ev, ctx, expr)

    Parameters: evaluator, context, and expression AST node. Returns: collection value. Evaluates an operand for collection operators.

  • builtin_can(value, method_name)

    Parameters: value is any value and method_name is a method name. Returns: Boolean. Tests whether built-in values support a method.
