and then i realized this was a little silly

sillystate.js

buffer = mmap.map(stats.size, mmap.PROT_READ, mmap.MAP_SHARED, fd, 0);
var lbl = new LineByLine(buffer);
var comment = ';'.charCodeAt(0);
var space = ' '.charCodeAt(0);
var xxx = '*'.charCodeAt(0);
var COMMENT = "comment";
var DEF = "definition";
var NULL = null;
var STATE = NULL;
var defbuff = '';
for (pos in buffer) {
  var current = buffer[pos];
  var states = {};
  states[[NULL, comment]] = COMMENT,
  states[[NULL, linesep]] = NULL,
  states[[NULL, space]] = NULL,
  states[[COMMENT, linesep]] = NULL,
  states[[DEF, linesep]] = NULL,
  states[[NULL, xxx]] = DEF,
  states[[COMMENT, xxx]] = COMMENT
  var current_symbol = current;
  if (!current.match(/\n| |;/)) {
    current = xxx;
  }
  STATE = states[[STATE, current]];
