Use a free font?

[Ryex]

It would be nice to have the fonts move away from a paid font.

I have written some scripts to make using icon fonts a bit easier

https://gist.github.com/Ryex/668faf884eaca5b310fdaaadef6895e3

the preprocess_fontcss.lua takes a font's css file and builds a lua table of the font icons with names that map to their css names so you can require the table and map the names and take advantage of autocomplete instead of copy pasting each icon. the font tables are current as of a month ago.

personally, I was slowly replacing the icons in my own config with icons from Nerdfont and Weathericons with some form Remix icons. but you can of course use which ever fonts you want.

Would you mind sharing that code / making a PR?

you've updated the function and the icon names since I did it but this is the mapping it did.

note that the remixicon names often have an option between _fill and _line and my choices on each one were mostly based on which had more visual contrast to be easy to see on a dark background. your choices may be different.

I didn't have perfect replacement for every icon, especially for the apps.

I tried switching over to nerdfont, but the issue with that is since they have icons from many different sets I need to manually set a different size for each icon so they look identical in size
