Programming with ncurses

Over at Linux Journal, I am writing an article series about programming on Linux. While graphical user interfaces are very cool, not every program needs to run with a point-and-click interface. So in my "Getting started with ncurses" article series, I discuss how to write programs using the ncurses library functions.

Maybe you aren't familiar with curses or ncurses, but I guarantee you've run programs that use this library. Many programs that run in "terminal" mode, including vi editor, use the curses set of functions to draw to the screen. The curses functions allow you to put text anywhere on the screen, or read from the keyboard.

My article series starts with a simple example that demonstrates how to put characters and text on the screen. My example program is a chaos game iteration of Sierpinski's Triangle, which is a very simple program (only 73 lines).

Follow-up articles in the series will include a "Quest" program to demonstrate how to query the screen and use the arrow keys, and how to add colors.

Linux Journal has posted the second part of my article series: Creating an adventure game in the terminal using ncurses. And part three: Programming in color with ncurses. Soon to come: why the Linux console only has sixteen colors, and how to use windows and frames in ncurses.
