blark.transform.ForStatement

class blark.transform.ForStatement(control: SimpleVariable | MultiElementVariable, from_: Expression, to: Expression, step: Expression | None, statements: StatementList, meta: Meta | None = None)[source]

Bases: Statement

A loop with a control variable and a start, stop, and (optional) step value.

Examples:

FOR iIndex := 0 TO 10
DO
    iValue := iIndex * 2;
END_FOR

FOR iIndex := (iValue - 5) TO (iValue + 5) BY 2
DO
    arrArray[iIndex] := iIndex * 2;
END_FOR

Lark grammar

This class is used by the following grammar rules:

Methods

`__init__`(control, from_, to, step, statements)
`from_lark`()

Attributes

control: SimpleVariable | MultiElementVariable

from_: Expression

to: Expression

step: Expression | None

statements: StatementList

meta: Meta | None = None

__init__(control: SimpleVariable | MultiElementVariable, from_: Expression, to: Expression, step: Expression | None, statements: StatementList, meta: Meta | None = None) → None

from_lark() → T
