- lang.l, lang.y (MIL2MM): moved unit conversion from lang.l to lang.y
- lang.l, lang.y: instead of returning dimensions and numbers as NUMBER,
return as NUM_EXP_<unit> for numbers with an explicit unit, and as
NUM_IMP_<unit> if the unit is implied
- lang.y (dimen): perform unit conversion as needed
- lang.y (number): never convert and only accept implicit dimensions
- lang.y: change all uses of NUMBER to "dimen", except for the
multipliers in "array", where we can now use "number"
- lang.y: removed comment about "array" only working in metric mode
- README, lang.y: changed depth parameter of "z" command to position
(sign changes)
- lang.l: defer FILENAME after "gerber" and "gnuplot", so that we don't
mis-read the number
- lang.l, lang.y: return the reference point after "align" as new token
REF, not as NUMEBER, so that we can catch syntax errors that would
cause scanner and parser to become unsynchronized
- lang.l: accept negative numbers
- lang.l: added support for comments beginning with #
