🌐 Native Variables

DI provides these predefined variables for use in your scripts. They give you instant access to device and installer details.

Variable	Descripción
`$TMP`	Temporary directory that exists only during execution.
`$addons`	Temporary directory containing all the contents of `META-INF/addons`.
`$l`	Temporary directory containing the main environment binaries.
`$BOOTMODE`	`true` if the device is booted, `false` otherwise.
`$ARCH`	Device architecture (`arm64-v8a` or `armeabi-v7a`).
`$chipname`	Chipset type (`snapdragon`, `exynos`, `mediatek`. `kirin`, `unisoc`).
`$installzip`	Path to the ZIP being installed.
`$is64bit`	`true` if the device is 64-bit, `false` otherwise.
`$API`	Android API version number (`33` for Android 13).
`$slot`	Active slot (`_a` or `_b`) for A/B devices; refresh with `getarch`.
`$dynamic_partitions`	`true` if the device uses dynamic partitions, `false` otherwise.
`$virtual_partitions`	`true` if the device has virtual dynamic partitions, `false` otherwise.
`${n}`	Inserts a newline in strings (`"Line1${n}Line2"`).
`$encrypted`	`true` if internal memory is encrypted, `false` otherwise.
`$di_version`	Full version of Dynamic Installer (e.g., `4.8-bZ2`).
`$main_version`	Main version of DI (e.g., `4.8`, without variant tags).
`$CUSTOM_SETUP`	`0` (normal install), `1` (Test Mode), `2` (external like KSU).

tip

When the ZIP installation process begins, META-INF/addons are automatically extracted. So it is possible to refer to them with the addons variable.

fprint "$addons/myaddon.txt"

Example Usage

fprint "$addons/banner.txt" # From META-INF/addons/banner.txt

# Using variables about the device and environment
ui_print "-- Installing on $ARCH device with API: $API"

if $BOOTMODE; then
    ui_print "-- Device is BOOTED"
else
    ui_print "-- Running in Recovery or something else"
fi

if $is64bit; then
    ui_print "-- 64-bit device"
else
    ui_print "-- 32-bit device or something else"
fi

create_file "$TMP/file.txt"   # Create a temporary file
