# Learning Flex and Bison
## Description
This repository was created to keep track of my personal learning material for [Flex and Bison][flexandbison].
The source code is provided in the [src](src/) directory, the explanations and notes are stored inside the [notes](notes/) directory.
## Build
You can generate the lexcial analyzer and the parser using the [build script](build.sh) in the root directory.
It expects exactly one parameter, which is the path to the lexical analyzer description.
After hitting enter the script will delete the `build` directory if existing, generate a new one and save the lexical analyzer just there as well as the generated parser and the corresponding header file.
Last but not least **gcc** will create an executable you can run afterwards.
**Note:** The build script was created for a MacOS system and may not work on other systems.
Furthermore, be sure to have Flex and Bison installed!
### Example
```shell
$ ./build.sh flex/binary.l
$ ./build/binary.exe
1101 + 10 * 11
= 19
```
