# Magisk Module Template Config Script
# by topjohnwu
#
##########################################################################################
##########################################################################################
#
# Instructions:
#
# 1. Place your files into system folder (delete the placeholder file)
# 2. Fill in your module's info into module.prop
# 3. Configure the settings in this file (config.sh)
# 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
#

# Set to true if you need late_start service script

  # set_perm  $MODPATH/system/lib/libart.so       0       0       0644

  # The following is default permissions, DO NOT remove
  set_perm_recursive  $MODPATH  0  0  0755  0644
  
  # Permissions for the props file
  set_perm $MODPATH/system/$BIN/props 0 0 0777
  # Permissions for boot scripts
  set_perm $LATEFILE 0 0 0755
  set_perm $POSTFILE 0 0 0755

# Custom Functions
##########################################################################################

# This file (config.sh) will be sourced by the main flash script after util_functions.sh
# If you need custom logic, please add them here as functions, and call these functions in
# update-binary. Refrain from adding code directly into update-binary, as it will make it
# difficult for you to migrate your modules to newer template versions.
# Make update-binary as clean as possible, try to only do function calls in it.
