Constructors

Step !Int

Run a specific number of steps

StepUntil (Pred VM)

Finish when a VM predicate holds

data Continuation a Source #

Each step command in the terminal should finish immediately with one of these outcomes.

Stopped a

Program finished

Continue (Stepper a)

Took one step; more steps to go

interpret :: (?fetcher :: Fetcher, ?maxIter :: Maybe Integer) => StepMode -> Stepper a -> StateT UiVmState IO (Continuation a) Source #

This turns a Stepper into a state action usable from within the TTY loop, yielding a StepOutcome depending on the StepMode.

runFromVM :: Maybe Integer -> DappInfo -> (Query -> IO (EVM ())) -> VM -> IO VM Source #

takeStep :: (?fetcher :: Fetcher, ?maxIter :: Maybe Integer) => UiVmState -> StepMode -> EventM n (Next UiState) Source #

backstep :: (?fetcher :: Fetcher, ?maxIter :: Maybe Integer) => UiVmState -> EventM n UiVmState Source #

appEvent :: (?fetcher :: Fetcher, ?maxIter :: Maybe Integer) => UiState -> BrickEvent Name e -> EventM Name (Next UiState) Source #

opWidget :: (Integral a, Show a) => (a, Op) -> Widget n Source #
