# GodMode9 "Hello Script"
# Tutorial script - read / run this to learn how it works
# last changed: 20170706
# author: d0k3

# COMMENTS / SCRIPTING BASICS / 'echo' COMMAND
# Anything after '#' will be ignored by the scripting engine
# Commands and arguments are separated by whitespaces, any redundant whitespaces will be ignored
# Use '"' if an argument has to include whitespaces
# The echo command outputs info on screen
echo "'Hello Script'\nby d0k3\n \nThis is a sample script to\nshowcase the GM9 script engine." # comments work anywhere
# Unknown commands lead to script abort (remove the '#' below to test)
# iamunknown test test

# 'ask' COMMAND / (-o/-s) SWITCHES
# The 'ask' command is similar to the 'echo' command, but will allow the user to abort
# Note that normally any failed command (like a negative user response on 'ask') will result in script abort
ask "Continue running this script?"

# (-o/-s) SWITCHES
# You may use the -o / --optional and -s / --silent switches on any command
# -o / --optional continues on failures
# -s / --silent tries to suppress all error messages
# This would have completely ignored the user response on the previous command:
ask -o -s "Really continue running this script?\n(I will completely ignore your answer)"

# ENVIRONMENTAL VARS
# SERIAL is the serial number of your device
# GM9OUT is the standard ouptput path
# SYSID0 is the id0 belonging to your SysNAND
# EMUID0 is the id0 belonging to your EmuNAND (if available)
# Use $[VAR] to get the *content* of a variable VAR
echo "Your serial number is $[SERIAL]\nYour std output path is $[GM9OUT]\n \nYour sys / emu ID0 is:\n$[SYSID0]\n$[EMUID0]"

# ERRORMSG and SUCCESSMSG / 'set' COMMAND
# These two are special environment vars, allowing you to control the message on script failure or success
set ERRORMSG "HelloScript testing script failed"
set SUCCESSMSG "HelloScript testing script success"
# you can also reset these to return to default script messages
# set ERRORMSG ""
# set SUCCESSMSG ""

# CREATING VARS
# You can also create new variables using 'set'
# Notice how you can use variables when setting variables
set TESTPATH 0:/testdir/$[SERIAL]_tick.db
echo "Your testpath is:\n$[TESTPATH]"

# 'allow' COMMAND
# typically used at the beginning of a script, prompts to allow writes to the location given in the argument
# doing this from the beginning is preferable, so that no actions are taken unless all required write permissions are unlocked
# (note #1: without 'allow', write permissions are still in place and the user will be asked on demand)
# (note #2: this simple testing script requires no additional permissions, thus the command is hidden behind a '#')
# -a / -all allows writes to the specified location and all included files and directories
# allow -a M:/

# 'rm' COMMAND
# The 'rm' command is used to remove files and directories (recursively)
# Here, we remove the dir if it is still here from an earlier run of this script
# If it is not here, we ignore any errors and keep silent about it
rm -o -s 0:/testdir

# 'mkdir' COMMAND
# Use this to create a directory at the specified location
mkdir 0:/testdir

# 'imgmount' COMMAND
# The 'imgmount' command is used to mount an image.
# An image can be (among other things) FAT, NAND, NCCH, NCSD, FIRM, ticket.db...
imgmount S:/ctrnand_full.bin

# 'cp' COMMAND
# Use 'cp' to copy a file or directory (recursively)
# -h / --hash also adds a .sha file containing the files SHA256
# -w / --overwite forces overwrite on existing files
# -k / --skip forces skip on existing files
# -n / --no_cancel prevents user cancels (useful on critical operations)
cp -h -w -n 7:/dbs/ticket.db $[TESTPATH]

# 'imgumount' COMMAND
# This unmounts the current mounted image.
imgumount

# 'findnot' COMMAND
# Use 'findnot' in conjunction with '?' to find an unused filename
findnot $[TESTPATH]_???.rn RENPATH

# 'mv' COMMAND
# The 'mv command renames or moves a file or directory
# -w / --overwite forces overwrite on existing files
# -k / --skip forces skip on existing files
# -n / --no_cancel prevents user cancels (useful on critical operations)
mv -w -k $[TESTPATH] $[RENPATH]

# 'find' COMMAND
# The 'find' command has two main uses, (1) checking if files / dirs exist and (2) finding files / dirs
# Here we use it to check for RENPATH, thus we use NULL as second argument (we're not interested in the output)
find $[RENPATH] NULL
# Wildcards ('*' / '?') are allowed when searching for a file / directory name:
# find S:/nand.* NANDIMAGE

# 'sha' COMMAND
# Use this to check a files' SHA256
sha $[RENPATH] $[TESTPATH].sha
# Instead of an .sha file you can also use the SHA256 in hex as second argument
# sha S:/sector0x96.bin 82F2730D2C2DA3F30165F987FDCCAC5CBAB24B4E5F65C981CD7BE6F438E6D9D3

# 'inject' COMMAND
# This command is used to inject part of one file into another
# The syntax is: inject origin@x:y destination@z
# x: origin offset (in hex)
# y: origin size, starting at x (in hex)
# z: destination offset (in hex)
# -n / --no_cancel prevents user cancels (useful on critical operations)
inject S:/nand_hdr.bin@100:4 $[RENPATH]@200 # offsets and sizes are in hex
# As we just deliberately corrupted our test file, the subsequent SHA check will fail
set ERRORMSG "SHA check failed (this was expected)"
sha -o $[RENPATH] $[TESTPATH].sha
set ERRORMSG ""

# 'verify' COMMAND
# Certain file formats (NAND, NCCH, NCSD, CIA, FIRM, ...) can also be verified. Use 'verify' to do so.
# verify -o s:/firm0.bin # As drive letters are case sensitive, this would fail
verify S:/firm1.bin

# 'reboot' / 'poweroff' COMMAND
# These are used to reboot or power off the 3DS console
set ERRORMSG "Test script finished,\n(without reboot)\n \nIgnore the error message."
ask "Reboot now?"
reboot
poweroff # this line can never be reached
