I wrote a simple terminal program of Matrix digital rain. A part of the purpose of this program is to test the performance of terminal emulators. Another purpose is just for fun. Enjoy it with fast terminals (e.g., urxvt, alacritty, terminology, etc.)!
Features
- Hankaku kana characters as in the original film
- Ten levels of "green"s using terminal 256 color support
- Twinkling effects by adding random brightness fluctuations
- Diffused reflection effects by cell background colors
Scenes
By default, the following scenes will be visited in turn.
If you want to see each scene, please see the help (cxxmatrix --help).
- Number falls
- Banner - Show command line arguments by shining characters
- "The Matrix" rain - Wikipedia
- Conway's Game of Life - Wikipedia
- The Mandelbrot set - Wikipedia
- (End scene) "The Matrix" rain
- cxxmatrix in 80x28 - Youtube
- The Mandelbrot set in 479x186 - YouTube
- Highlight scenes - See the animated GIF below

Compile MSYS2 binary (MSYS2 PTY) using MSYS2
The MSYS package msys2-devel is required in order to use the MSYS2 compiler.
msys2$ pacman -Syu
msys2$ pacman -S git gawk make msys2-devel
msys2$ git clone https://github.com/akinomyoga/cxxmatrix.git
msys2$ cd cxxmatrix
msys2$ PATH=/usr/bin:$PATH makeCompile Windows binary (ConPTY) using MinGW/MSYS2
The Windows binary based on Windows Pseudo Console API (ConPTY) can be compiled on MinGW/MSYS2 by passing TARGET=win32 to make.
It should be noted that ConPTY is extremely slow.
msys2$ pacman -Syu
msys2$ pacman -S git gawk make mingw-w64-x86_64-gcc

-- The rest arguments are processed as MESSAGE
-m, --message=MESSAGE
Add a message for 'banner' scene.
-s, --scene=SCENE
Add scenes. Comma separated list of 'number', 'banner', 'rain',
'conway', 'mandelbrot', 'rain-forever' and 'loop'.
-c, --color=COLOR

--frame-rate=NUM
Set the frame rate per second. A positive number less than or
equal to 1000. The default is 25.
--error-rate=NUM

non-negative number. The default is 1.0.
--diffuse
--no-diffuse
Turn on/off the background-color effect. Turned on by default.
--twinkle
--no-twinkle

./cxxmatrix -s number,conway,loopsudo make installThe default install prefix is /usr/local. The following files will be created:
/usr/local/bin/cxxmatrix/usr/local/share/man/man1/cxxmatrix.1.gz/usr/local/share/licenses/cxxmatrix/LICENSE.md
The make variable PREFIX can be specified to change the install prefix.
To copy files in a temporary location, the make variable DESTDIR can also be specified.
To change the subdirectory of LICENSE.md, the make variable INSTALL_SUBDIR_LICENSE (whose detault value is share/licenses/cxxmatrix) can be adjusted.
# Example 1: install cxxmatrix in user directory
make install PREFIX=~/.local
# Example 2: install cxxmatrix in /opt
