There's an AUR package:
$ git clone https://aur.archlinux.org/packages/c-lolcat
$ cd c-lolcat
$ makepkg -csi
$ dnf install lolcat
See this awesome blog post by a kind person from the internet:
$ snap install lolcat-c
Build loclcat with:
$ make lolcat
...and put the resulting binary at a place of your choice.
Note: Debian users may need the python-is-python3
package.
$ make && sudo make install
This lolcat
clone is an attempt to reduce the world's carbon dioxide emissions by optimizing inefficient code. It's >10x as fast and <0.1% as large as the original one.
