flex-bison-example

A reentrant example parser with custom parameters with flex/bison

Install prerequisites. On Debian-based Linuxes, like:

$ apt-get install -y build-essential flex bison

Build using the Makefile

$ make

then run like so:

$ out/calc

Exit the calculator with exit command or Ctrl-D.

reentrant parser
pass custom parameters to parser and lexer
get custom data back from parser and lexer
print line number in error messages
compile source files individually, then link (as you would do in a larger code base)
separate sources and generated files into src and out dirs
