optable [Latin: optabilis] (obsolete) That may be chosen; desirable.

A website with (reverse) opcode tables for various CPUs. Work in progress.

Inspired by Pastraiser's opcode tables and based on the GBDev Game Boy opcode table website.

Each architecture has two directories:

• collections/<arch>/: HTML and Markdown templates
• _data/<arch>/: Data sources
  • generate_opcodes.py: Script that generates opcodes.json
  • instructions.json: JSON file with all instructions
  • flags.json: JSON file with flag registers

The file structure isn't very logical right now. The templates in collections shouldn't need to be duplicated per architecture, and should probably live in _layouts somehow. Pull requests rectifying this are very welcome.
