I don't know. How would you implement "less" in Python? How would you
implement "nethack" in Python?
On my system:
Apfelkiste:~ chris$ otool -L /usr/bin/less
/usr/bin/less:
/usr/lib/libncurses.5.4.dylib (compatibility version 5.4.0,
current version 5.4.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 1225.0.0)
So "less" in C uses ncurses.
On mine (Fedora 24):
========================================================================
$ ldd $(which less)
linux-vdso.so.1 (0x00007ffdbbb79000)
libtinfo.so.6 => /lib64/libtinfo.so.6 (0x00007f8d72678000)
libc.so.6 => /lib64/libc.so.6 (0x00007f8d722b6000)
/lib64/ld-linux-x86-64.so.2 (0x000055e31be7e000)
========================================================================
Notably missing is: /usr/lib64/libncurses.so.6
Interesting. So your less does it in a different way than mine. I peeked
into the sources, and it seems that less uses either tinfo, xcurses,
ncursesw, ncurses, curses, termcap or termlib on nNix-like systems. On
Windows it uses WIN32getch(). So there is no "one obvious way" to do
this in C, but a large variety of options - just like in Python.
