* Negroni
An emulator for the mythical computer "MIX" from Donald Knuth's /The Art of Computer Programming/.
There are two components to negroni:
- ~stir~ :: The MIX emulator
- ~shake~ :: The MIXAL assembler
** ~stir~
This MIX emulator is fairly fully-featured, and almost all operations are implemented,
but there are a few exceptions and limitations:
*** Limitations
- Writing to memory being accessed by an ~OUT~ operation, or reading memory
being accessed by an ~IN~ operation will cause a panic.
*** Missing features
- Floating point operations (~FADD~, ~FSUB~, ~FMUL~, ~FDIV~, ~FCMP~) are not implemented.
- Only a binary version of MIX is emulated.
- No timing information is captured.
- Typewriter and paper tape I/O is not supported.
** ~shake~
*** Limitations
- String literals (for ~ALF~ operations) must be wrapped in double quotes.
- Remarks at the end of a line must begin with a ~#~.
*** Missing features
- W-values are not supported beyond a single expression.
- Invalid usage of future values do not cause errors, and produce invalid programs.
*** Note
Please don't actually shake a negroni; it bruises the gin.
