The ncurses library allows for full-screen text control in the Unix terminal environment. Text is written to a specific window then refreshed to update the window and view the output.
- [Instructor] NCurses is a C language library … that provides direct manipulation … of the terminal window text screen, … as well as keyboard input. … If you've ever used a full-screen program … in a terminal window, such as the vi editor, … it was most likely created by using NCurses. … The library you want to install … in your terminal window package manager … is libx32ncurses5-dev. … Now on the Mac, the brew formula is simply NCurses. … This library works only in the Unix shell environment. … In Windows, you can run NCurses programs … in the Ubuntu Linux terminal. … Or if you use the Cygwin environment, … you can run NCurses programs there as well. … Once installed, you can compile and link this exercise file … to confirm the NCurses installation. … The sample code shows the ncurses.h header file, … included at line two, which defines the string constant … NCURSES_VERSION output at line six. … To compile the code, type your compiler name, … I prefer clang, … and I like to activate all the warnings. …
