Generating from Noto Emoji

[evolucja]

Hello,
is there any way of generating a font directly from .svgs from the https://github.com/googlefonts/noto-emoji/tree/main/svg ?
It looks the naming is a little bit different and I don't know how to handle it.

Maybe anyone will find a few minutes and could have a look on that? Would appreciate.

PS this is very a good work and nicely described project!

Best regards
Dave

I'm also interested! 😸

Thanks for the kind words @evolucja 😄

Yes, you can generate the font directly from .svgs! As for the name differences, you'll just have to find a way to convert them into Apple's format. I've tried to include everything you need to know in the README.md. It's quite a few files though, so I'd recommend figuring out how the naming pattern works/differs and then making a quick script to rename the files.

Hope this helps!

I've renamed all the SVGs just removing emoji_u and give it a try to see how many emojis were missing. The script generated 1283 PNGs in 9 different size on 3577 total emojis.
I decided to build the font anyway, just expecting missing emojis.

Sadly I get errors which I don't think are connected to the missing pictures:

macmoji create font

Base emoji files already exist. Use `--force` to overwrite them.

The 9 PNG versions for the u1F1EA emoji are present. 🤔

Strange. Have you tried running macmoji create base-files? Use the --force flag if it complains.

My guess for what's going on is that the program is having issues writing to ~/Library/Application Support (the place for storing application data for Mac apps). If this is the case, I don't have a solution right off the bat.
