# Build instructions
|
|
|
|
Typically build the CBDT then the COLRv1 as COLRv1 copies some information from CBDT.
|
|
|
|
## CBDT
|
|
|
|
```bash
|
|
rm -rf venv # in case you have an old borked venv!
|
|
python3 -m venv venv
|
|
source venv/bin/activate
|
|
pip install -r requirements.txt
|
|
python size_check.py
|
|
rm -rf build/ && time make -j 48
|
|
# Should take 2-3 minutes to create noto-emoji/NotoColorEmoji.ttf
|
|
|
|
mv *.ttf fonts/
|
|
```
|
|
|
|
## COLRv1
|
|
|
|
```bash
|
|
# If you are updating to a new Unicode rev, update configs
|
|
python colrv1_generate_configs.py
|
|
git diff colrv1/*.toml
|
|
|
|
# Compile the fonts
|
|
(cd colrv1 && rm -rf build/ && time nanoemoji *.toml)
|
|
cp colrv1/build/NotoColorEmoji.ttf fonts/Noto-COLRv1.ttf
|
|
cp colrv1/build/NotoColorEmoji-noflags.ttf fonts/Noto-COLRv1-noflags.ttf
|
|
|
|
# Post-process them
|
|
python colrv1_postproc.py
|
|
```
|
|
|
|
## Emojicompat
|
|
|
|
```
|
|
# Add support for new sequences per https://github.com/googlefonts/emojicompat#support-new-unicode-sequences
|
|
# Install https://github.com/googlefonts/emojicompat in a venv
|
|
# Create emojicompat versions of the fonts you made
|
|
# Starting from the root of noto-emoji-next:
|
|
|
|
$ pushd fonts
|
|
$ cp NotoColorEmoji.ttf NotoColorEmoji-emojicompat.ttf
|
|
$ cp Noto-COLRv1.ttf Noto-COLRv1-emojicompat.ttf
|
|
$ emojicompat --op setup --font NotoColorEmoji-emojicompat.ttf
|
|
$ emojicompat --op setup --font Noto-COLRv1-emojicompat.ttf
|
|
$ emojicompat --op check --font NotoColorEmoji-emojicompat.ttf
|
|
$ emojicompat --op check --font Noto-COLRv1-emojicompat.ttf
|
|
|
|
# The emojicompat --op check step should print something akin to:
|
|
3835 items_by_codepoints
|
|
0 PUA missing
|
|
0 PUA point at wrong glyph
|
|
3835 PUA correct
|
|
0 Emji entries did NOT match a glyph
