Shpadoinkle-debug: Debugging tools for Shpadoinkle applications.

[ bsd3, deprecated, library, web ] [ Propose Tags ] [ Report a vulnerability ]
Deprecated in favor of Shpadoinkle-console

Shpadoinkle tooling is a work in progress. But some useful functions have already emerged. This repo centeralizes these functions, and will house future work on more robust tooling, such as time travel debugging.

Shpadoinkle Debug

Goldwater BSD-3 built with nix Hackage Hackage Deps Hackage CI

This package exposes some useful debugging functions for tracing the state of Shpadoinkle applications as they change over time. It exposes 2 type classes currently.

class LogJS (c :: Type -> Constraint) where
  logJS :: c a => a -> JSM ()

class LogJS c => Trapper c where
  trapper :: c a => JSContextRef -> a -> a

These are intended to by used with TypeApplications, so you can choose the means of conversion before passing to console.log. For example:

main :: IO ()
main = runJSorWarp 8080 $ do
  ctx <- askJSM
  simple runParDiff initial (view . trapper @ToJSON ctx) getBody

Will log all state by first encoding to JSON with Aeson, then then logging with JSON.parse so the browser console has the nice native display. If we change it to trapper @Show ctx it will use the Show instance instead.
