Documentation
startChartServer :: Maybe String -> IO (ChartOptions -> IO Bool, IO ()) Source #
Start the chart server. Returns the chart consumer, and a server quit signal effect.
An iconic ghci session transcript:
> import Chart.Examples > (sendChart, quitChartServer) <- startChartServer (Just "prettychart") > sendChart unitExample
... point browser to localhost:9160 ...
> quitChartServer
startChartServerWith :: SocketConfig -> Page -> IO (ChartOptions -> IO Bool, IO ()) Source #
Start the chart server protocol with bespoke SocketConfig and Page configurations.
startChartServerWith (defaultSocketConfig & #port .~ 4567) (defaultSocketPage & #htmlBody %~ divClass_ "row" "bespoke footnote")
printChart :: Show a => Bool -> (ChartOptions -> IO Bool) -> a -> IO () Source #
Print a chart supplying a ChartOptions consumer, and a showable thing that may be chartable. The first argument flags whether to also print the item to stdout.
chartSocketPage :: Maybe ByteString -> Page Source #
Page containing a web socket and javascript needed to run it.
