ruby - How do I create an interactive menu in a terminal? -


i'm trying build terminal application that, when started, take user away prompt , present them screen interactive menu. user able interact in following way:

  1. they start application running my_app terminal. start application , present them root menu.
  2. they use cursor keys navigate around menu , use [enter] key make selection.
  3. when make selection, presented screen/menu when work. when finished work, press key take them root menu.

the key thing i'm after not scrolling view adds more information end. i'd have distinct, encapsulated views navigation hierarchy. problem don't know how produce such view , present user, , dismiss again once they're done. if give me kind of design pattern kind of application, i'll able take there.

fwiw, i'm using ruby , app cross-platform. if that's ask, windows suffice.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
