Re: ocamllex eating up line breaks even when not asked to

I see. My mistake was to treat special classes of characters as « keywords », the correct
way to proceed is to treat them in the rules section directly :

  | '\n'
  | '\r' as lb
    { LINEBREAK lb}
  | '|'
  | '\"'
  | '\''
  | '='
  | '`'
  | ','
  | '?'
  | ':'
  | '('
  | ')'
  | '{'
  | '}' as pnct
     {PUNCTUATION_MARK pnct} 


It works now, thank you.
