A very simple code generator to make it easier to use Flex/Bison (Lex/Yacc) in C++.
Don't expect magic :)

This project is based on the Jonathan Beard's tutorial:
http://www.jonathanbeard.io/tutorials/FlexBisonC++

After downloading the code...

./create.sh <grammar> <namespace>

will generate a few files in the output folder that are ready to be modified/incremented and used inside a C++ project.

Replace <grammar> by a grammar name and <namespace> by the name space in which all classes will be declared.

Even without modifications, the generated code is ready to be compiled and tested. The default parser will read numbers, strings and identifiers echoing them back to the screen.

To test...

./create.sh Echo Parser
cd output/test
make
./Echo

and type some numbers, strings and identifiers.

An example of output:

24061960
Integer: 24061960
counter
Identifier: counter
"porto alegre"
String: porto alegre
2.71828
Float: 2.71828

sudo apt-get install flex (flex >= 2.6)
sudo apt-get install bison
