So very cool. I just built and installed it on my MacBook. Looks great on Apple's standard terminal, and I think a little bit better even on ITerm 2.

#12A long time ago I wrote gomatrix: https://github.com/GeertJohan/gomatrix
It's a Matrix emulator inspired by cmatrix. It doesnt have as many features as this posts one (e.g. just 2 colors for the kanas), but was a fun exercise to learn Go. Pull requests welcome :)

You made it further than I did. The majority of machines out there today probably do not support the required -std=c++17. I know none of my OS installs (and their compilers) do.

Thank you for your comment. Do you have some screenshots, animated GIFs or videos of gomatrix which I can link from cxxmatrix README (https://github.com/akinomyoga/cxxmatrix#the-matrix-rains-in-...)? I could only find unofficial one https://www.youtube.com/watch?v=mUXFxSmZMis (maybe I can add a link to this unofficial one)

I think Xcode has shipped with a compliant C++17 compiler for over a year, but I used GCC to compile this one :)

Interestingly, it was exceedingly laggy on Terminal.app for me. iTerm seemingly handled it better.

Thank you. This issue is discussed here https://github.com/akinomyoga/cxxmatrix/issues/3
It is caused by the UTF-8 unaware awk. I haven't yet figured out why it happens, but at least you need to set your locale to one of UTF-8 locales.

GCC has supported this for more than a year, too (at least since 7.4.0).

Thanks, that is what I tried to say: better on ITerm.
