Re: Which lexer do people use?

[John P. Hartmann]

For the scanner and parser I maintain on UNIX and then transport to the 
EBCDIC world of the mainframe, I had to write my own scanner, but I can 
get by with Bison as long as I don't use character constants in rules 
(IBM 360 assembler in rules does work).  There were a few other hoops, 
such as no more a tables-only bison option.

For other work, which is all in C, flex seems satisfactory.  Call me 
oldfashioned.
