This example will soon use GNU readline, so its scanner should be easy to use (concurrently) on strings, not streams. This is not a place where Flex shines, and anyway, these are examples of Bison, not Flex. There's already lexcalc and reccalc that demonstrate the use of Flex. * examples/c/bistromathic/scan.l: Remove. * examples/c/bistromathic/parse.y (yylex): New. Adjust dependencies.
This directory contains examples of Bison grammar files, sorted per language.
Several of them come from the documentation, which should be installed together with Bison. The URLs are provided for convenience.
These examples come with a README and a Makefile. Not only can they be used to toy with Bison, they can also be starting points for your own grammars.
Please, be sure to read the C examples before looking at the other languages, as these examples are simpler.
