Yes.

I'll make it line-based.

I was hoping to use actual KeySyms (like BackSpace) as well if
possible.

> pointerevent is closer to the protocol.

Yes, I'd misread the spec as having deltas.

Here's my new attempt:

file ::= version password? shared? default-delay? line*
version ::= 'RFM 001.000\n'
password ::= 'password ' string '\n'
string ::= '"' char* '"' | "'" char* "'"
char ::= '\\' | '\"' | '\'' | [^\\\n]
shared ::= 'shared\n'
default-delay ::= 'default ' delay '\n'
delay ::= 'delay ' time
time ::= number 's'
       | number 'ms'
number ::= [0-9]+
line ::= command? comment? '\n'
command ::= key delay?
          | press delay?
          | type delay?
          | pointer delay?
          | button delay?
          | cut
key ::= 'key ' keysym ' up'
      | 'key ' keysym ' down'
keysym ::= keysymname | '0x' [0-9]{2} | '0x' [0-9]{4}
keysymname ::= [A-Za-z0-9_]+
press ::= 'press ' keysym
type ::= 'type ' string
pointer ::= 'pointer ' delta ' ' delta
          | 'pointer ' number ' ' number
delta ::= '+' number
        | '-' number
button ::= 'button ' number ' up'
         | 'button ' number ' down'
cut ::= 'cut\n' base64-data
comment ::= ' '? '#' .*

<base64-data> is any number of lines in RFC2045 base64 format,
terminated by a newline or comment.

Comments?

Tim.
