Readme for ghci-websockets-0.0.2

[back to package description]

ghci-websockets

With ghci-websockets you can send data from GHCi straight to the browser, using a websocket connection that survives GHCi reloads.

The Ghci.Server.Websockets module implements the actual websocket server, sending JSON objects to all clients. Ghci.Server.Http servers the index.html page that goes with the messages defined in Ghci.Websockets.Message.

Quickstart

Add ghci-websockets to the build-depends field of your .cabal file
Run cabal new-repl
Run Ghci.Server.start
Open localhost:3000 in a browser
In GHCi, run Ghci.Server.sendText "hello" (see also sendHtml and sendPlot from the same module). You may need :set -XOverloadedStrings.

Warning

This packages uses the foreign-store package internally, which is highly unstable. I wouldn't use ghci-websockets for anything other than GHCi.
