Arguments
| :: (TriggerEvent t m, PerformEvent t m, MonadIO (Performable m), PostBuild t m, MonadIO m, MonadFix m, MonadHold t m) | |
| => CreateProcess | Command to run to enter GHCi |
| -> Maybe ByteString | Expression to evaluate whenever GHCi successfully loads modules |
| -> Event t () | Ask GHCi to reload |
| -> m (Ghci t) |
Runs a GHCi process and reloads it whenever the provided event fires
ghciWatch :: (TriggerEvent t m, PerformEvent t m, MonadIO (Performable m), PostBuild t m, MonadIO m, MonadFix m, MonadHold t m) => CreateProcess -> Maybe ByteString -> m (Ghci t) Source #
Run a GHCi process that watches for changes to Haskell source files in the current directory and reloads if they are modified

Arguments
| :: (Reflex t, MonadFix m, MonadHold t m) | |
| => Behavior t Bool | Whether to clear the output on reload |
| -> Ghci t | |
| -> m (Dynamic t ByteString) |
Collect all the GHCi module output (i.e., errors, warnings, etc) and optionally clear every time GHCi reloads
Arguments
| :: (Reflex t, MonadFix m, MonadHold t m) | |
| => Behavior t Bool | Whether to clear the output on reload |
| -> Ghci t | |
| -> m (Dynamic t ByteString) |
Collect all the GHCi expression output (i.e., the output of the called function) and optionally clear every time GHCi reloads
Arguments
| :: (Reflex t, MonadFix m, MonadHold t m) | |
| => Event t () | Clear output |
| -> Event t ByteString | Output to add |
| -> m (Dynamic t ByteString) |
Collect output, appending new output to the end of the accumulator
statusMessage :: IsString a => Status -> a Source #
Describe the current status of GHCi in a human-readable way
