# Magisk Module Installer Script
#
##########################################################################################
##########################################################################################
#
# Instructions:
#
# 1. Place your files into system folder (delete the placeholder file)
# 2. Fill in your module's info into module.prop
# 3. Configure and implement callbacks in this file
# 4. If you need boot scripts, add them into common/post-fs-data.sh or common/service.sh
# 5. Add your additional or modified system properties into common/system.prop
#
##########################################################################################
##########################################################################################
# Config Flags
##########################################################################################
# Set to true if you do *NOT* want Magisk to mount
# any files for you. Most modules would NOT want
# to set this flag to true
SKIPMOUNT=false
# Set to true if you need to load system.prop
PROPFILE=false
# Set to true if you need post-fs-data script
POSTFSDATA=false
# Set to true if you need late_start service script
LATESTARTSERVICE=true
##########################################################################################
# Replace list
##########################################################################################
# List all directories you want to directly replace in the system
# Check the documentations for more info why you would need this
# Construct your list in the following format
# This is an example
REPLACE_EXAMPLE="
/system/app/Youtube
/system/priv-app/SystemUI
/system/priv-app/Settings
/system/framework
"
# Construct your own list here

#
# Function Callbacks
#
# The following functions will be called by the installation framework.
# You do not have the ability to modify update-binary, the only way you can customize
# installation is through implementing these functions.
#
# When running your callbacks, the installation framework will make sure the Magisk
# internal busybox path is *PREPENDED* to PATH, so all common commands shall exist.
# Also, it will make sure /data, /system, and /vendor is properly mounted.
#
##########################################################################################
##########################################################################################
#
# The installation framework will export some variables and functions.
# You should use these variables and functions for installation.
#
# ! DO NOT use any Magisk internal paths as those are NOT public API.
# ! DO NOT use other functions in util_functions.sh as they are NOT public API.
# ! Non public APIs are not guranteed to maintain compatibility between releases.
#
# Available variables:
#
# MAGISK_VER (string): the version string of current installed Magisk
# MAGISK_VER_CODE (int): the version code of current installed Magisk
# BOOTMODE (bool): true if the module is currently installing in Magisk Manager
# MODPATH (path): the path where your module files should be installed
# TMPDIR (path): a place where you can temporarily store files
# ZIPFILE (path): your module's installation zip
# ARCH (string): the architecture of the device. Value is either arm, arm64, x86, or x64
# IS64BIT (bool): true if $ARCH is either arm64 or x64
# API (int): the API level (Android version) of the device
#
# Availible functions:
#
# ui_print <msg>
# print <msg> to console
# Avoid using 'echo' as it will not display in custom recovery's console
#
# abort <msg>
# print error message <msg> to console and terminate installation
# Avoid using 'exit' as it will skip the termination cleanup steps
#
# set_perm <target> <owner> <group> <permission> [context]
# if [context] is empty, it will default to "u:object_r:system_file:s0"
# this function is a shorthand for the following commands
# chown owner.group target
# chmod permission target
# chcon context target
#
# set_perm_recursive <directory> <owner> <group> <dirpermission> <filepermission> [context]
# if [context] is empty, it will default to "u:object_r:system_file:s0"
# for all files in <directory>, it will call:
# set_perm file owner group filepermission context
# for all directories in <directory> (including itself), it will call:
# set_perm dir owner group dirpermission context
#

# If you need boot scripts, DO NOT use general boot scripts (post-fs-data.d/service.d)
# ONLY use module scripts as it respects the module status (remove/disable) and is
# guaranteed to maintain the same behavior in future Magisk releases.
# Enable boot scripts by setting the flags in the config section above.
