Building a Graphical IDE in Elm/Purescript
summary
Built a visual IDE for a PLC language that compiles PLC to BEAM and talks over websockets to a Cowboy handler on embedded boards, using Elm 0.16 with Elm 0.16 nested startups and JSON decoders, rendering with SVG rendering with CSS for interactive variable plots; the demo runs in realtime and aids debugging. Porting decisions leave the project on 0.16 to avoid rewrite pain, and subsequent work moves parts to PureScript for ported parts to PureScript to gain advanced types, Halogen, and tighter JS interop.
