About abishekvashok/cmatrix
CMatrix is an open-source terminal screensaver that simulates the falling green text effect from the movie 'The Matrix'. Based on the screensaver from the official Matrix website, it displays characters cascading down the terminal in a visually similar fashion. Users can configure the scroll speed, color, and choose between synchronous or asynchronous line scrolling. The program is lightweight, built on the ncurses library, and works on Linux and Windows (via mingw or PDCurses). It can be installed using either the standard configure/make process or CMake. The project is maintained on GitHub with contributions from the community.

FAQ
How do I install cmatrix?
Clone the repository and use either the configure/make method (recommended for Linux) or CMake. For configure: run 'autoreconf -i', './configure', 'make', then 'make install'. For CMake: create a build directory, run 'cmake ..', then 'make && make install'.
How do I run cmatrix?
After installation, simply type 'cmatrix' in your terminal. You can pass command-line options for different effects, e.g., 'cmatrix -lba' for the movie-like appearance.
What are the system dependencies?
CMatrix requires the ncurses library. On Linux, check with 'ldconfig -p | grep ncurses'. On Windows, mingw-w64-ncurses or PDCurses is recommended.
How can I make cmatrix look most like the movie?
Use the command 'cmatrix -lba'. This enables the matrix-like display mode with bold and asynchronous scrolling.
