PackageUtils were previously based on using `Context` object to get app info, which was only possible to get for Termux app and its sharedUserId plugins. Now it has been refactored to used `PackageInfo` and `ApplicationInfo` objects to get the info, which will also allow getting info of external apps. However, when targeting sdk `30`, queries entries or `QUERY_ALL_PACKAGES` permission will be required. Check `PackageUtils.isAppInstalled()` for more info.
./gradlew lint complains about vibrations being used in
termux-shared/src/main/java/com/termux/shared/terminal/io/BellHandler.java
without the permission being declared.
The `TextIOActivity` can be used to edit or view text based on various config options defined by `TextIOInfo`
and supports `monospace` font and horizontal scrolling for editing scripts, etc.
Current max text limit is `95KB`, which can be increased in future.
This can be used to check if `Termux:API` is installed and enabled for cases where users try to run `termux-api` commands and it hangs. The check can be added to start of each `termux-api` script during build time by replacing a placeholder with `sed`.
```
if dpkg --compare-versions "$TERMUX_VERSION" ge 0.118 && [ -z "$TERMUX_API_VERSION" ]; then
echo "The Termux:API app is not installed or enabled which is required by termux-api commands to work." 1>&2
exit 1
fi
current_user="$(id -un)"
termux_user="$(stat -c "%U" "/data/data/com.termux/files/usr")"
if [ "$current_user" != "$termux_user" ]; then
echo "The termux-api commands must be run as the termux user \"$termux_user\" instead of as \"$current_user\"." 1>&2
echo "Trying to run with \"su $termux_user -c termux-api-command\" will fail as well." 1>&2
exit 1

This is being done since github release artifacts may be converted to non-debuggable if felt appropriate in future or at least is a more appropriate name. Signing keys can stay same as per commit/push builds. Currently, no changes are planned, just future proofing. The `TERMUX_IS_DEBUGGABLE_BUILD` env variable could be used to differentiate if needed.
Will also check if Termux app is installed and not disabled and will calculate APK signature only when needed since its a slightly expensive operation.
This commit breaks da07826a.
The `TERMUX_IS_DEBUG_BUILD` env variable will be set to `1` if termux APK is a debuggable APK and `0` otherwise. Note that the `dev_keystore.jks` shipped with termux app and plugin source code can also be used to create a release APK even though its mainly used for Github Debug Builds, in which case value will be `0`.
The `TERMUX_APK_RELEASE` will be set to `GITHUB_DEBUG_BUILD`, `F_DROID` or `GOOGLE_PLAY_STORE` depending on release type. It will be set to `UNKNOWN` if signed with a custom key.
The `TERMUX_APP_PID` will be set to the process of the main app process of the termux app package (`com.termux`), assuming its running when shell is started, like for `termux-float`. This variable is included since `pidof com.termux` does not return anything for release builds. It does work for debug builds and over adb/root. However, you still won't be able to get additional process info with `ps`, like that of threads, even with the pid and will need to use adb/root. However, `kill $TERMUX_APP_PID` will work from `termux-app` and `termux-float`.
These variables can be used by termux devs and users for custom logic in future depending on release type.
Previously, `FileUtilsErrno` had some errors that didn't include the full path passed to the `FileUtils` functions and caller had to manually append the path to the error. This was done due to `termux-tasker` plugin config activity was using these errors in the executable and working directory text fields and we had to keep the error short as possible to reduce clutter. Now by default, the path will be included so that its not missing for other cases and the `FileUtils.getShortFileUtilsError()` function is provided to get a shorter version from the original error if its possible to do so if caller like `termux-tasker` requires it.
The user can add `extra-keys-text-all-cap=false` entry to `termux.properties` file to disable auto capitalization of extra keys text for both normal and popup buttons. The default value is `true`. Running `termux-reload-settings` command will also update the behaviour instantaneously if changed.
The `TermuxUtils.isTermuxAppInstalled()` function can be used by external apps to check if termux app is installed and enabled.
The `TermuxUtils.isTermuxAppAccessible()` function can be used by termux plugin apps to check if termux app is installed, enabled, accessible as per `sharedUserId` and `TERMUX_PREFIX_DIR_PATH` is accessible and has read, write and execute permission.
We manually create the parent directories first so that bootstrap failures are detected early on instead of some sub directory during extraction.
Also fixed issue where `TermuxFileUtils.isTermuxFilesDirectoryAccessible()` would not check if a directory file actually existed at TERMUX_FILES_DIR_PATH and may set permissions for a non-directory file at the path. The `TermuxInstaller` was testing if `TERMUX_PREFIX_DIR_PATH` existed later on so check wasn't necessary but function may be called from elsewhere too.
Also removed legacy `PREFIX_FILE*` and `STAGING_PREFIX_FILE*` local constants and use the ones provided by `TermuxConstants` directly.
Since termux-app runs in a separate process from other apps, if a user sets log level in termux settings, then it would require exiting the `termux-app` completely since android caches `SharedPrefernces` in memory and only writes to the file on app exit. Now updated value will be instantly written to the file so that plugins can directly read at startup. If plugins are already running, they would need to be restarted since usually log levels are loaded at startup.
Also added log level setting in Termux Settings for Termux:API. Others can be added when logging is implemented in the plugin apps via `Logger` class provided by `termux-shared`.
