I'm in business.
The lexer reads a chunk from the file into its buffer, and then
forgets about the file and its file position. So no rule moves the
file offset at all; it is only changed when the buffer runs out of
characters, and needs to be refilled.
In a lexer .c file with this option on, there is a segment right
before the lexer switch statement that looks something like:
This seems more "acceptable".
How does it manage unput and similar re-feed?
All stuff is handled via the lexer buffer, and no stuff is put back
into the file.
if ( yy_act != YY_END_OF_BUFFER && yy_rule_can_match_eol[yy_act] )
{
yyfilepos += yyleng;
}
You should have something like that.
