Linux Curses：Unlock the Power of Command Line Interfaces（linuxcurses）

Linux Curses is a library for creating text-based user interfaces. It’s a handy tool for command line interface (CLI) programmers that allows them to easily create a text-based user interface for their scripts and programs. Curses provides a rich library of functions that developers can use to create menus, windows, buttons, and more.

Curses is particularly powerful for creating fast, efficient command-line programs that run on Linux-based systems. It allows developers to quickly and easily create text-based UI elements in their software. This means users can quickly access scripts and programs, as well as see results or errors quickly. It also eliminates the need for users to type complicated code every time they want to interact with a program.

To use curses, developers need to include the curses library in their programs. They can do this with the following line of code:

#include

Once the library is included, developers can use any of the functions in it to create their user interface. For example, the following code creates a simple window in which users can enter information:

WINDOW *win;

win = newwin(20, 80, 0, 0);

cbreak();

mvwprintw(win, 1, 1, “Welcome to my interface!”);

Once the window is set up, developers can create menus and buttons with the mvwprintw() function. They can also use the getch() function to capture user input and the wrefresh() function to update the window, ensuring that any changes made to it are visible to the user.

Curses is a powerful tool for creating text-based command line user interfaces. It simplifies the process of creating menus, windows, and other UI elements, allowing developers to create powerful, intuitive interfaces with fewer lines of code. Its rich library of functions helps developers expand their UI programmatically, quickly and efficiently.
