Custom C implementation of nm and otool commands.

• ft_nm <args> displays the name list (symbol table of nlist structures) of the <args> files
• ft_tool displays the content of the (__TEXT,__text) segment

This project will makes you understand how Mach-O files are structured.

make

# Clean commands
make clean
make fclean
make re

# Files supported: exec, .a, .so, .dylib, .o.
./ft_nm file
./ft_otool file

• Support for archives
• Support for fat binaries
• Support for debug symbols (gcc -g <args> files).
• Many flags (see ./ft_nm -h or ./ft_otool -h)
• Checks for corruption

To understand how I implemented this program, you can refer to the medium article of this project.
