the trouble is fontawesome now supplies multiple files,
fa-brands-400.woff2, fa-regular-400.woff2 and fa-solid-900.woff2.
don't know which symbol is in which file.
list all defined symbols into a file:
grep 0x ../ngui/lib/lvgl/src/font/lv_symbol_def.h | grep -v 0x2022 | \
cut -d, -f2 | cut -c4-7 | tr 'A-F' 'a-f' \
> /tmp/sym.txt
download and unzip fontawesome. expect to find metadata/icons.yml file.
grep metadata to find out which set each icon is in:
for c in $(cat /tmp/sym.txt); do
t=$(grep -B3 "unicode: $c" metadata/icons.yml | grep -- '- ' | head -n1 | tr -d ' -')
echo "$c\t$t"
done
some icons are in multiple styles. search for the code on https://fontawesome.com/icons/
and compare to the image on https://docs.lvgl.io/8.3/overview/font.html.
the command above takes the first one listed in icons.yml, which is usually "solid".
when searching on fontawesome, make sure it's a free icon, as opposed to their pro version.
not all icons might be present. at the time of writing, the following codes are amiss:
- 0xf067 `LV_SYMBOL_PLUS`; actually exists but listed as unicode:2b in icons.yml
- 0xf8a2 `LV_SYMBOL_NEW_LINE`; looks like fontawesome removed `level-down-alt` from v6
so i picked an alternative 0xf177 `arrow-left-long`
dump previous command output into an fa-icon-style.txt file. add missing "solid" style
in the second column and replace f8a2 with `f177=>0xf8a2` mapping. the latter is
the syntax for when running [lvgl font convertion tool](https://github.com/lvgl/lv_font_conv).
while there, add more codes to the file, separating columns with a single tab:
- 0xf379 brands (bitcoin)
- 0xe0b4 solid (bitcoin-sign)
- 0xf0e7 solid (lightning bolt)
split the previously generated fa-icon-style.txt file into chunks suitable for
constructing lvgl's font converter arguments.
first, check which styles are present. at the moment, only "brands" and "solid"
are used:
$ cut -f2 fa-icon-style.txt | sort | uniq -c
3 brands
61 solid
then split the file, for each style from the previous command. example for "solid":
grep solid fa-icon-style.txt | cut -f1 | tr 'a-f' 'A-F' | \
while IFS= read -r line; do printf "0x$line\n"; done | \
paste -s -d, | tr -d '\n' > fa-solid.txt
typically, you'll want to bundle the symbols from fontawesome with a regular font.
i'll use [courier prime code](https://github.com/quoteunquoteapps/courierprimecode)
as an example.
install the font converter tool; requires nodejs:
npm i lvgl/lv_font_conv
finally, convert and bundle all fonts, for 14px size as an example:
./node_modules/.bin/lv_font_conv --no-compress --no-prefilter --bpp 4 --size 14 \
--font courier-prime-code.ttf -r 0x20-0x7F,0xB0,0x2022 \
--font fa-brands-400.ttf -r $(cat fa-brands.txt) \
--font fa-solid-900.ttf -r $(cat fa-solid.txt) \
--format lvgl --force-fast-kern-format \
-o lv_font_courierprimecode_14.c
the arguments are similar to those in the header of any LVGL font in `lib/lvgl/src/font/lv_font/xxx.c`.

wpa_supplicant and hostapd
--------------------------
Copyright (c) 2002-2022, Jouni Malinen <j@w1.fi> and contributors
All Rights Reserved.
These programs are licensed under the BSD license (the one with
advertisement clause removed).
If you are submitting changes to the project, please see CONTRIBUTIONS
file for more instructions.
This package may include either wpa_supplicant, hostapd, or both. See
README file respective subdirectories (wpa_supplicant/README or
hostapd/README) for more details.
Source code files were moved around in v0.6.x releases and compared to
earlier releases, the programs are now built by first going to a
subdirectory (wpa_supplicant or hostapd) and creating build
configuration (.config) and running 'make' there (for Linux/BSD/cygwin
builds).
