Well, first of all, The Matrix is the best Sci-Fi movie ever made, and the green code rain alone inspired me like few other things ever have.
Yes, it's yet another matrix code generator. Cmatrix is one of my favorite programs, but after a few days learning Python I thought to myself, "Hey I could do this myself, maybe better, the right way". And I think I did okey.
I've gone back to the source material, and tried to really figure out how to make it look like the original. The beautiful thing is, if you disagree with the result, you can change it to your own liking! :-)
git clone https://github.com/elundmark/yapymatrix.git
cd yapymatrix/
chmod u+x yapymatrix
./yapymatrix [ options ]To stop the program, use Ctrl + C. I am not planning on adding any keyboard shortcuts, but who knows what happens in the future.
Here's the current list of options. This can also be printed by executing yapymatrix --help

YAPYMatrix 0.4.1 (2019-10-24) Highly customizable Matrix Code Emulator written
in python [https://github.com/elundmark/yapymatrix]
optional arguments:
-h, --help show this help message and exit
-V, --version show program's version number and exit
-f FPS, --fps FPS Frames per second, or delay between updates to be
precise. This will be converted to 1 / fps and used as
seconds to sleep between updates. If this is over 60,
sleep will be omitted (Default: 21)
-s STOP_AFTER, --stop-after STOP_AFTER
Stop program after N loops, useful if you want to have
it on for a while but not forever (Default: 0)
-b, --force-black Color all backgrounds black. Normally your terminals
default color-scheme will be used (Default: False)
-C, --no-colors Do not use any colors. This will speed up things quite
a bit, so think of using this if you are using
something like cool-retro-term (Default: False)
-B, --no-bold-characters
Do not use any bold characters (Default: False)
-l, --sparse-columns This will skip every other column, to make it look a
little lighter. Works best on wide terminals. Plus it
speeds up things a bit (Default: False)
-L, --very-sparse-columns
This will skip 2 of 3 column, to make it look a lot
lighter. Works best on wide terminals. Plus it speeds
up things a lot (Default: False)
-t, --tv-intro This skips a step when the program starts, and it will
look more like an old crt television warming up. This
started out a a bug, but now I kinda like it, so I
made it an optional extra (Default: False)
--include-spaces INCLUDE_SPACES
The original matrix code has spaces included in the
strings, which I don't think I've seen in any other
versions. Experimenting with this value will increase
the amount it will 'sparkle', or set it to 0 to
disable spaces entirely (Default: 3)
--onscreen-letters-timer ONSCREEN_LETTERS_TIMER
This might be the most important part imo; how long
should the characters 'stick' in one place? The number
represents the maximum amount of times it shows before
it is replaced. Randomness is also added to make it
look organic (Default: 5)
--random-bold RANDOM_BOLD
Make characters bold by a random chanse of 1 in N.
Making this 0 will not turn off bold characters
completely, to do this, use --no-bold-characters
instead (Default: 8)
-R ROGUE_AGENTS, --rogue-agents ROGUE_AGENTS
This makes N columns randomly go twice as fast
(Default: 0)
--spaces-abs-min-height SPACES_ABS_MIN_HEIGHT
Minimum height of vertical spaces (Default: 5)
--spaces-abs-max-height SPACES_ABS_MAX_HEIGHT
Maximum height of vertical spaces (Default: 35)
--spaces-rel-max-height SPACES_REL_MAX_HEIGHT
Maximum height of vertical spaces, relative to the
terminals height (--spaces-abs-max-height will
override this value if it is lower) (Default: 0.8)
--strings-abs-max-height STRINGS_ABS_MAX_HEIGHT
Maximum height of vertical strings (Default: 25)
--strings-abs-min-height STRINGS_ABS_MIN_HEIGHT
Minimum height of vertical strings. Cannot be lower
than 5 (Default: 5)
--strings-rel-max-height STRINGS_REL_MAX_HEIGHT
Maximum height of vertical strings, relative to the
terminals height (--strings-abs-max-height will
override this value if it is lower) (Default: 0.6)
--vertical-cache VERTICAL_CACHE
Advanced: Vertical cache. The bigger you set this to,
the more time passes before anything repeats, but it
requires more ram and will require more time to
calculate on startup. You should probably leave this
value alone (Default: 7)
- Tested in Python >=
3.7.3. - Best used with a true color terminal that has
draw_bold_text_with_bright_colorsset totrue. - Best used with the Matrix Code NFI Font.
- Bold characters with this font will not work, but it still looks pretty good.
Runs best in a gpu accelerated terminal like alacritty. See sample config below.
This is heavier than the original cmatrix. Can't be helped.
I have really tried to make it faster, but I think I have squeezed all the performance I can out of it, for now.
This was my first ever python script, so be kind when commenting! At the time I'm writing this I've only been exposed to python for a week.
Install the Matrix Code NFI font if you haven't already.
Add this to i3 config:
for_window [class="Alacritty" instance="yapymatrix"] focus, fullscreen toggle
