f77lexer.l, f77parser.y, all contens of src/*
f77.h file at working directorydon't forget to link math library during compilation -lm
bash scripts/build.sh or 3 following commands
bison -o "${PROJECT_DIR}/src/f77parser.c" "${PROJECT_DIR}/f77parser.y" -d flex -o "${PROJECT_DIR}/src/f77lexer.c" "${PROJECT_DIR}/f77lexer.l"g++ -o lexer src/classes.cpp src/classes.h src/defs.h src/f77parser.h src/f77lexer.c src/f77parser.c src/utils.h src/utils.cpp src/debug.h src/global.h -lm
bash scripts/translate.sh <input_file> <output_file> by default it translates example.f to example.cor you could directly ran executable "${PROJECT_DIR}/cmake-build-debug/lexer" using stdin for Fortran77 and stdout for C
running executable file with -d flag outputs fortran code tokenization to stderr
