Syntax highlighting and indentation rules for Chip8 assembly. These rules will apply to any *.8o file.
Full support for the SuperChip and XO-Chip instruction sets is available, but not enabled out-of-the-box. Read below for directions.

Supported keywords:
  conditionals:  begin, else, end, if, then, while
      constants:  buzzer, const, delay, key
       functions:  bcd, jump, jump0, load, save, sprite
          repeats:  again, loop
    statements:  :alias`, :breakpoint, :next, :unpack, clear, return

There is also syntax highlighting for named subroutines, integer/hex/binary values, and comments.


Auto-indentation will trigger for the following cases
  * indent one shiftwidth on lines following `loop`
  * indent one shiftwidth on lines following `while`
  * unindent to matching `loop` when ending it with `again`
  * indent one shiftwidth on lines following `if ... begin` and `else`
  * unindent to matching `if ... begin` when ending it with `end`
  * indent to zero for new labels
  * indent one shiftwidth on lines following new labels
  * indent to zero when ending a subroutine with `;`


SuperChip

An expanded set of keywords are supported for the SuperChip instruction set. To enable these uncomment out the following line in syntax/8o.vim:
  "let b:superChip = 1

Supported keywords:
    constants:  bighex
     functions:  hires, loadflags, lores, saveflags, scroll-down, scroll-left, scroll-right
  statements:  exit


XO-Chip

Another set of keywords are available to support the XO-Chip instructions. These are also disabled by default but can be turned on by uncommenting out the following line in syntax/8o.vim:
  "let b:superChip = 1

Supported keywords:
    constants:  long
     functions:  plane, scroll-up
  statements:  audio
