Using Local Font Files

Location

Place your font file in ~/.config/webshell/ as one of the following:

• font.woff2 (Create your own if needed! See below)
• font.ttf
• font.otf

The webshell will automatically encode and load your font file into the web browser upon login.

Determining Font Family Name from a Font File

fc-scan will return the font family name for you. It is possible to return multiple aliases so you can use the first one to simplify the process.

$ fc-scan GoogleSansCodeNerdFontMono-SemiBoldItalic.ttf --format "%{family}\n" | cut -d, -f1
GoogleSansCode Nerd Font Mono

Use woff2 files instead of ttf or otf

These are normal font files, but compressed so it will be nicer for web use:

# one at a time
for f in *.ttf *.otf; do woff2_compress "$f"; done
# use all those cores!
parallel woff2_compress ::: *.[ot]tf

On 181 of my fonts the size dropped from 381M to 220M.
