• Lua

  • Lua code formatter - reformat Lua code. (Currently most popular repository.)
    • command-line generator for code formatter - GUI to generate Bash command line for Lua code formatter. Possibly nicer way to learn than reading screen help.
  • Lua table serializer - store table as loadable string with Lua code
  • Autoldoc - automatically place LDoc comments in Lua source file
  • Workshop - code hive. Resource base for most of my projects.

• Arduino

  • DS3231 GUI - graphical interface to manage real-time clock module DS3231. (I like it.)
  • Arduino sketchbook - mess of my C sketches/libraries for Arduino.

• Docs

  • Reference docs
    • Zip format - official text docs with my .pdf equivalents
    • DS3231 - datasheet for real time clock chip DS3231
  • Tagging style - system of marking commit messages
  • Firmata protocol - Firmata protocol description. (Firmata protocol is related to Arduino world.)
