my ttf fonts
copy the fonts to ~/.fonts dir (if dir is not there create one)
$ cd ~/.fonts
$ mkfontscale
$ mkfontdir
$ ttmkfdir -o fonts.dir
$ fc-cache -f -v ~/.fonts
$ fc-cache -f -v
$ fc-match NonExistingFont
You can confirm that the fonts are installed with the following command:
$ fc-list | grep "Hack"
PS: The nerd-fonts submodule is really big
GPLv2+, just like Mercurial.
