Parse::Flex is not intended to be used directly; instead, use the +script makelexer.pl to submit your grammar file. The output of the script +is a custom shared library and a custom .pm module which, among other +things, will transparently load the library and provide interface to your +(custom) lexer. In other words, you supply a grammar.l file to +makelexer.pl and you receive Flex01.pm and Flex02.so . Then, use only the +Flex01.pm - since Flex01.pm will automatically load Flex01.so. + +The grammar.l file requires the same syntax as flex(1); that is, the +actions are written in C . See the flex(1) documentation to learn the +syntax, or fetch the sample t/grammar.l file inside this package. + +WWW: http://search.cpan.org/dist/Parse-Flex +Author: Ioannis Tambouras <ioannis@earthlink.net> |
