To interject. The 'modern' notion of spaces is in accord to how we now
understand how parser-generators work, most particularly how BNF works.
But in times long past this understanding was not understood. In Fortran
II, IV, 77 spaces had no meaning. This meant all of:
xy and x y were the sa

Driver.hh has class "driver" defined with scan_begin() and scan_end()
defined but Driver.cc doesn't have the body for these functions. Are
these functions defined?
Also in driver::parse (const std::string &f). "parse.set_debug_level
(trace_parsing);" is executed a

I have searched the Bison 3.8.1 manual and can't find where this is
defined. Can someone point me to the description of %option and its values?

I found the body for Driver::scan_begin and Driver::scan_end in
scanner.ll. Shouldn't this be colocated with the Driver class source
code? I (personally) have never seen the body of a class prototype
function defined in any other location than the class source. Isn't this

To intrude on this discussion just a bit, let me just say that I have
twice volunteered to rewrite portions of the Bison manual, twice refused
- never by a response - and many times asked questions. I have even sent
partial rewrites, with appropriate signatures, and (lis
shift/reduce/pop/push are part of LALR(1) parsing (see
https://en.wikipedia.org/wiki/LALR_parser as a start). Basically what
happens is that the parser forms lookahead sets. The creation and
sustenance of the lookahead sets is done with the pushes and pops. When
the LALR(1) parser looks at the
