.. _stdlib_is_local: ======================== is_local_xxx ast helpers ======================== The is_local module exposes collection of helper routines to establish locality of expression. All functions and symbols are in "is_local" module, use require to get access to it. :: require daslib/is_local ++++++++++++ Scope checks ++++++++++++ * :ref:`is_local_expr (expr: ExpressionPtr) : bool ` * :ref:`is_local_or_global_expr (expr: ExpressionPtr) : bool ` * :ref:`is_scope_expr (expr: ExpressionPtr) : bool ` .. _function-is_local_is_local_expr_ExpressionPtr: .. das:function:: is_local_expr(expr: ExpressionPtr) : bool Returns true if the expression is local to the current scope. :Arguments: * **expr** : :ref:`ExpressionPtr ` .. _function-is_local_is_local_or_global_expr_ExpressionPtr: .. das:function:: is_local_or_global_expr(expr: ExpressionPtr) : bool Returns true if expression is local the current scope or global scope. :Arguments: * **expr** : :ref:`ExpressionPtr ` .. _function-is_local_is_scope_expr_ExpressionPtr: .. das:function:: is_scope_expr(expr: ExpressionPtr) : bool Returns true if the expression is a scoped expression, i.e. eventually points to a variable. :Arguments: * **expr** : :ref:`ExpressionPtr ` +++++++++++++ Uncategorized +++++++++++++ .. _function-is_local_is_temp_safe_ExpressionPtr: .. das:function:: is_temp_safe(expr: ExpressionPtr) : bool Returns true if the exression had no calls, [] or table [] operators of any kind.
