Software
#1

I hope @FManga will forgive my impatience, but I can’t help but share a great new software development tool that I’m really excited about.

I will write short features that I noticed during the tests, but the author may add more details in the description later.

Beta version of multiplatform online JS IDE made by @FManga
for creating games and applications
(Pokitto, Gamebuino, ESPboy support implemented).

  • Online JS editor, compiler and emulator
  • Ability to load compiled applications on ESPboy from browser

MicoJS Online IDE

Quick Intro:

  • Generates native code, no VM/interpretor
  • Based on Monaco (VSCode’s editor)
  • Your sourcecode is stored in your browser but can be exported as a zip file
  • Aims for full JS language compatibility, not API/library compatibility
  • Full-res 8-bit graphics engine with sprite zoom/rotation/recoloring support
  • Built-in simulator runs well even on very slow devices
  • Games are platform-independent by default
  • Wiki documenting both the API and language
  • Autocomplete with documentation
  • Built-in asset conversion. Drag-and-drop an image into the file list and it’s ready
  • Uses a general-purpose palette, based on this paper.
  • Built-in ESPboy flashing support

Planned Features

  • Import zipped project
  • Project sharing between multiple users/browsers
  • More UI polish
  • Audio support
  • Tilemap support
  • Hotspot profiling (partially implemented already)
  • Built-in image editor
  • More JS language support (see wiki for up-to-date list of what’s missing)
