class GenericStmt(text: str, source: Source | str | None = None, label: str | None = None)

Bases: LeafNode, _GenericStmtBase

Catch-all generic node for corner-cases.

This is provided as a fallback for any statements that do not have an appropriate representation in the IR. These can either be language features for which support was not yet added, or statements that are not relevant in Loki’s scope of applications. This node retains the text of the statement in the original source as-is.

Parameters:

• text (str) – The statement as a string.

• **kwargs (optional) – Other parameters that are passed on to the parent class constructor.

keyword = None

class ImplicitStmt(text: str | Tuple[Expression, ...] | None = 'NONE', source: Source | str | None = None, label: str | None = None)

Bases: GenericStmt

GenericStmt node that represents the IMPLICIT statement.

Parameters:

• text (str or Expression, optional) – Either a tuple of variable specifiers or a string; default: NONE

• **kwargs (optional) – Other parameters that are passed on to the parent class constructor.

keyword = 'IMPLICIT'

text: str | Tuple[Expression, ...] | None = 'NONE'

classmethod ensure_str_or_tuple(value)

class SaveStmt(text: Tuple[Expression, ...] | None = (), source: Source | str | None = None, label: str | None = None)

Bases: GenericStmt

GenericStmt node that represents the SAVE statement.

Parameters:

• text (str or Expression, optional) – Either a tuple of variable specifiers or a string; default: NONE

• **kwargs (optional) – Other parameters that are passed on to the parent class constructor.
