Headline numbers from a fresh `./gradlew assemble`:
- :commons material_symbols_outlined.ttf 11M -> 409K (subset to the 210
codepoints actually referenced from MaterialSymbols.kt)
- :amethyst per-ABI APKs no longer built in CI (-PdisableAbiSplits=true);
~600M of stripped_native_libs intermediates skipped per run
Changes:
- .git-hooks/pre-push runs only :amethyst:testPlayDebugUnitTest plus jvmTest
on the KMP modules instead of `./gradlew test`, which was compiling all six
amethyst variants (play/fdroid x debug/release/benchmark)
- amethyst/build.gradle adds three opt-in fast-build flags:
-PdisableAbiSplits=true skip per-ABI APK splits
-PdisableUniversalApk=true skip the universal APK output
-Pamethyst.skipMapping=true disable R8 (release+benchmark)
Defaults are unchanged; release pipelines must not set skipMapping.
- .github/workflows/build.yml uses gradle/actions/setup-gradle@v4 with
cache-read-only on PRs / cache-write on main, drops --no-daemon, collapses
the Android job to a single Gradle invocation (lint + focused debug unit
tests + assembleBenchmark with -PdisableAbiSplits=true), and globs both
APK naming patterns for the upload step.
- tools/material-symbols-subset/{subset.sh,README.md} regenerates the font
from upstream + MaterialSymbols.kt; run after adding/removing icons.
Verified: ./gradlew :amethyst:help with all three new -P flags parses cleanly,
and ./gradlew :commons:jvmJar --rerun-tasks succeeds with the subsetted font
(commons-jvm jar shrinks from ~13M to 2.9M).

# Material Symbols Subset
|
|
|
|
The font shipped at
|
|
`commons/src/commonMain/composeResources/font/material_symbols_outlined.ttf`
|
|
is a **subset** of Google's [Material Symbols
|
|
Outlined](https://github.com/google/material-design-icons) variable font,
|
|
trimmed to only the codepoints referenced from
|
|
`commons/src/commonMain/kotlin/com/vitorpamplona/amethyst/commons/icons/symbols/MaterialSymbols.kt`.
|
|
|
|
| | Full upstream | Subset |
|
|
|---|---|---|
|
|
| Size | ~11 MB | ~410 KB |
|
|
| Glyphs | ~3500 | ~210 |
|
|
|
|
The subset cuts >10 MB out of every commons build artifact, every Android APK,
|
|
and every Desktop app bundle.
|
|
|
|
## When to regenerate
|
|
|
|
Run `subset.sh` whenever you:
|
|
|
|
- add or remove a `MaterialSymbol("\uXXXX")` entry in `MaterialSymbols.kt`
|
|
- pin a newer upstream font version
|
|
|
|
## Prerequisites
|
|
|
|
```bash
|
|
pip install fonttools brotli
|
|
```
|
|
|
|
## Regenerating
|
|
|
|
From the repo root:
|
|
|
|
```bash
|
|
./tools/material-symbols-subset/subset.sh
|
|
```
|
|
|
|
That downloads the upstream variable font, intersects its codepoints with the
|
|
ones referenced from `MaterialSymbols.kt`, and overwrites the checked-in
|
|
`material_symbols_outlined.ttf`.
|
|
|
|
If you already have an upstream `.ttf` on disk:
|
|
|
|
```bash
|
|
./tools/material-symbols-subset/subset.sh /path/to/MaterialSymbolsOutlined-Regular.ttf
|
|
```
|
|
|
|
Commit the regenerated `.ttf` alongside the `MaterialSymbols.kt` change.
|
|
|
|
## How it works
|
|
|
|
`pyftsubset` (from `fonttools`) reads the codepoints we care about, drops every
|
|
glyph and OpenType feature not reachable from those codepoints, and rewrites
|
|
`name`, `cmap`, and `GSUB` tables accordingly. The Compose resource pipeline
|
|
treats the result as a normal TTF — no code changes needed.
