Variables

Usable Variables

• INSTALLER - Working directory of installer (source directory/origin of files to be installed)
• UNITY - Location to mod directory - equal to the magisk img directory if magisk, equal to nothing otherwise (destination directory). Note that almost every destination file/folder should be preceded by this variable (Ex: $UNITY$SYS/lib/file.so)
• BOOTMODE - Equal to true if in magisk manager, false otherwise
• ROOT - Location of root of file system such as with pixels using supersu (where instead of being nothing, is /system_root)
• SYS - Location of destination system folder - this is always equal to /system in the installer so it's real use is for boot and terminal scripts
• VEN - Location of destination vendor folder
• MODID - 'id' from module.prop - the unique identifier for your mod
• MODPATH - if magisk install - path to magisk mod directory. If system install - path to boot script directory. Useful for boot scripts
• LIBDIR - If DYNAMICOREO=true: Equal to /vendor if rom is oreo+, /system otherwise
• LIBPATCH - Same as libdir but formatted for sed with standard '/' delimiter
• MAGISK - Set to 'true' if magisk is detected, 'false' otherwise - Useful if you want parts to only run with/without magisk installs
• API - Taken from build.prop. Equal to the API version of the rom installed
• ABILONG - Taken from build.prop. Equal to the ABI version of the device
• ABI - Taken from build.prop. Equal to the ABI number (first 3 characters of ABILONG) of the device (equals either arm or x86)
• ABI2 - Taken from build.prop. Equal to the ABI2 number of the device (first 3 characters)
• ARCH - Equal to the cpu type of the device - equal to arm, arm64, x86, or x86_64
• ARCH32 - Equal to the simplified cpu type of the device - equal to 'arm' or 'x86'
• IS64BIT - Set to 'true' if 64 bit capable device is detected, set to 'false' otherwise
• ORIGDIR - The original directory for device files (original files unaffected by magisk mounting). Equals MAGISKTMP/mirror if in BOOTMODE, nothing otherwise (MAGISKTMP=/sbin/.magisk for magisk 18+ and /sbin/.core for older versions). This is useful if you're copying files from the device to your mod for modification.
• ORIGVEN - Equal to the original vendor directory. This is more complex than you'd think with magisk or else I wouldn't have it here
