Planned features

• wspls language server
  • Inline values for instruction names that are preserved while editing
  • Debugging
• wsvsc VS Code extension
  • Syntax highlighting
  • Render whitespace characters
  • Disassembly panel
• wsasm assembler
  • Support all dialects
  • Macros like Whitelips and others
  • Support constant or address arguments like WhitespaceAssembler
  • Linting
    • Warn on usage of multiple mnemonic for same instruction
    • Warn on inconsistent mnemonics between corresponding IO instructions
    • Warn on inconsistent mnemonic capitalization
• wsdisasm disassembler
  • Format according to dialect definition
  • Automatically collapse constant or address arguments
  • Format constants in ASCII range as chars
• wspack compresser
  • wsx-format compression and decompression
• wspace interpreter
  • File execution
  • Whitespace Assembly REPL

Languages

• Stack-based like Factor
  • First-class closures (see “Closure elimination as constant propagation”)

Architecture plans
