The bistromathic example should not use Flex, it makes it too complex. But it was the only example to show location tracking with Flex. * examples/c/lexcalc/lexcalc.test, examples/c/lexcalc/parse.y, * examples/c/lexcalc/scan.l: Demonstrate location tracking as is done in bistromathic.
bistromathic - all the bells and whistles
This example demonstrates the best practices when using Bison.
- Its interface is pure.
- It uses a custom syntax error with location tracking, lookahead correction and token internationalization.
- It supports debug traces with semantic values.
- It uses named references instead of the traditional $1, $2, etc.
It also uses Flex to generate the scanner.
