agnostic-apollo 897d911a52 Changed: Move to semantic versioning for app and library versions and add commit hash and github to APK file names
The `versionName` will now follow semantic version `2.0.0` spec in the format `major.minor.patch(-prerelease)(+buildmetadata)`. This will make versioning the prerelease and github debug builds versions easier and follow a spec. The @termux devs should make sure that when bumping `versionName` in `build.gradle` files and when creating a tag for new releases on github that they include the patch number as well, like `v0.1.0` instead of just `v0.1`. The `build.gradle` files and `attach_debug_apks_to_release` workflow will now validate the version as well and the build/attachment will fail if `versionName` does not follow the spec. https://semver.org/spec/v2.0.0.html

APKs released on github for debug build workflows and releases are now referred as `Github` releases as per 7b10a35f and 94e01d68, so APK filenames have been modified to include `github` in the filename. The APKs are still debuggable, so that tag remains too.

For github workflows the apk filename format will be `termux-app_<current_version>+<last_commit_hash>-github-debug_<arch>.apk`, like `termux-app_v0.1.0+xxxxxxxx-github-debug_arm64-v8a.apk` and for github releases it will be `termux-app_<release_version>+github-debug_<arch>.apk`, like `termux-app_v0.1+github-debug_arm64-v8a.apk`. The `last_commit_hash` will be the first `8` characters of the commit hash. The `<last_commit_hash>-github-debug` will act as `buildmetadata` and will not affect versioning precedence.

For github workflows triggered by `push` and `pull_request` triggers, `<current_version>+<last_commit_hash>` will be used as new `versionName`, like `v0.1.0+xxxxxxxx`. This will make tracking which build a user is using easier and help in resolving issues as well.

Note that users using github releases and termux devs using `$TERMUX_VERSION` environment variables in scripts should take commit hash into consideration and possibly use something like `dpkg --compare-versions "$TERMUX_VERSION" ge 0.1` where appropriate instead of mathematical comparisons.

The `app/build.gradle` now also supports following `TERMUX_` scoped environmental variables and `RELEASE_TAG` variable will not be used anymore since it may conflict with possibly other variables used by users. They will also allow enabling split APKs for both debug and release builds.

- `TERMUX_APP_VERSION_NAME` will be used as `versionName` if its set.
- `TERMUX_APK_VERSION_TAG` will be used as `termux-app_<TERMUX_APK_VERSION_TAG>_<arch>.apk` if its set. The `_<arch>` will only exist for split APKs.
- `TERMUX_SPLIT_APKS_FOR_DEBUG_BUILDS` will define whether split APKs should be enabled for debug builds. Default value is `1`.
- `TERMUX_SPLIT_APKS_FOR_RELEASE_BUILDS` will define whether split APKs should be enabled for release builds. Default value is `0` since F-Droid does not support split APKs, check #1904.

So based on above, if in future github releases are to be converted to `release` builds instead of `debug` builds, something like following can be done and even a workflow can be created for it. Users can also build split APKs release builds for themselves if they want.

```
export TERMUX_SPLIT_APKS_FOR_RELEASE_BUILDS=1
./gradlew assembleRelease -Pandroid.injected.signing.store.file="$(pwd)/app/dev_keystore.jks" -Pandroid.injected.signing.store.password=xrj45yWGLbsO7W0v -Pandroid.injected.signing.key.alias=alias -Pandroid.injected.signing.key.password=xrj45yWGLbsO7W0v
```

The APK will be found at `./app/build/outputs/apk/release/termux-app_<version>_<arch>.apk`

The `TERMUX_SPLIT_APKS_FOR_DEBUG_BUILDS` can be set to `0` to disable building split APKs which may be helpful for users building termux on device considering they will extra space and build time. Instructions for building are at https://github.com/termux/termux-packages/pull/7227#issuecomment-893022283.

```
export TERMUX_SPLIT_APKS_FOR_DEBUG_BUILDS=0
./gradlew assembleDebug
```

The APK will be found at `./app/build/outputs/apk/debug/termux-app_debug_universal.apk`

Note that F-Droid uses algorithm at https://gitlab.com/fdroid/fdroidserver/-/blob/2.1a0/fdroidserver/build.py#L746 to automatically detect built APKs, so ensure any modifications to location or file name are compliant. Current updates should be.
