  1. forceLookupM :: (Show key, Ord key) => String -> key -> Map key elt -> elt

    MissingH Data.Map.Utils

    Performs a lookup, and raises an exception (with an error message prepended with the given string) if the key could not be found.

  2. forceMaybe :: Maybe a -> a

    MissingH Data.Maybe.Utils

    Pulls a Just value out of a Maybe value. If the Maybe value is Nothing, raises an exception with error. Alias of fromJust.

  3. forceMaybeMsg :: String -> Maybe a -> a

    MissingH Data.Maybe.Utils

    Like forceMaybe, but lets you customize the error message raised if Nothing is supplied.

  4. forceSuccess :: PipeHandle -> IO ()

    MissingH System.Cmd.Utils

    Uses getProcessStatus to obtain the exit status of the given process ID. If the process terminated normally, does nothing. Otherwise, raises an exception with an appropriate error message. This call will block waiting for the given pid to terminate. Not available on Windows.

  5. forkRawSystem :: FilePath -> [String] -> IO ProcessID

    MissingH System.Cmd.Utils

    Invokes the specified command in a subprocess, without waiting for the result. Returns the PID of the subprocess -- it is YOUR responsibility to use getProcessStatus or getAnyProcessStatus on that at some point. Failure to do so will lead to resource leakage (zombie processes). This function does nothing with signals. That too is up to you. Logs as System.Cmd.Utils.forkRawSystem

  6. package foreign-store

    Store a stable pointer in a foreign context to be retrieved later. Store a stable pointer in a foreign context to be retrieved later. Persists through GHCi reloads.

  7. forestGreen :: T

    gnuplot Graphics.Gnuplot.ColorSpecification

    No documentation available.

  8. forceLabels :: Attribute

    graphviz Data.GraphViz.Attributes

    Force the positioning of xLabels, even when it will cause overlaps.

  9. forcePos :: Point -> Bool

    graphviz Data.GraphViz.Attributes.Complete

    Input to Graphviz only: specify that the node position should not change.

  10. forecast :: HasInputOpts c => Lens' c (Maybe DateSpan)

    hledger-lib Hledger.Read.Common

    No documentation available.
