# COLRv1 Build

We assume the bitmap version with equivalent coverage exists and
contains emojicompat metadata.

## Build Steps

1. Check the list of sources in the config files is in sync with the current sources

   ```shell
   # running from the noto-emoji repository root directory
   python colrv1_generate_configs.py
   git diff colrv1/*.toml
   ```

   If configs are in sync, the `colrv1/*.toml` files should contain no diffs.

1. Compile the COLRv1 fonts

   ```shell
   time nanoemoji *.toml
   cp build/NotoColorEmoji.ttf ../fonts/Noto-COLRv1.ttf
   cp build/NotoColorEmoji-noflags.ttf ../fonts/Noto-COLRv1-noflags.ttf
   ```

1. Post-process COLRv1 font for Android
   * At time of writing only the noflags version is for Android

   ```shell
   # Assumed to be in a python3 environment with requirements.txt fulfilled
   python colrv1_postproc.py colrv1/build/NotoColorEmoji-noflags.ttf \
   	PATH_TO/NotoColorEmojiCompat.ttf
   ```
