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

The output of the GHCi process

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
