Learning Flex and Bison\n\n## Description\n\nThis repository was created to keep track of my personal learning material for [Flex and Bison][flexandbison].\nThe source code is provided in the [src](src/) directory, the explanations and notes are stored inside the [notes](notes/) directory.\n\n## Build\n\nYou can generate the lexcial analyzer and the parser using the [build script](build.sh) in the root directory.\nIt expects exactly one parameter, which is the path to the lexical analyzer description.\nAfter 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.\nLast but not least **gcc** will create an executable you can run afterwards.\n\n**Note:** The build script was created for a MacOS system and may not work on other systems.\nFurthermore, be sure to have Flex and Bison installed!\n\n### Example\n\n```shell\n$ ./build.sh flex/binary.l\n$ ./build/binary.exe\n1101 + 10 * 11\n = 19\n```\n\n\n[flexandbison]:
