<file bash mine.lua>--Civilwargeeky's Quarry Program--
--https://github.com/civilwargeeky/Civils_Progs--
  VERSION = "3.6.4.5"
--[[
Recent Changes:
  Parameter Files! Create a file of parameters, and use -file to load it!
    Works will with -forcePrompt
  Quarry no longer goes to start at end of row!
  Turtle can go left!
  QuadCopters! Check Lyqyd's thread
New Parameters:
    -overfuel/fuelMultiplier [number]: This number is is what neededFuel is multiplied by when fuel is low.
    -version: This will display the current version number and end the program
    -file [fileName]: This will load a custom configuration file (basically a list of parameters). "##" starts comment lines. In the future "#" will start programs to run (but only through shell)
    -preciseTotals [t/f]: If true, turtle will write exactly what it mined to the logs. It may also transmit it over rednet.
    -forcePrompt [param]: This will add to a list of parameters to force prompt for. So if you say "-forcePrompt doRefuel" it will prompt you "Length","Width","Height","Invert","Do Refuel" etc.

local help_paragraph = [[
Welcome!: Welcome to quarry help. Below are help entries for all parameters. Examples and tips are at the bottom.
-default: This will force no prompts. If you use this and nothing else, only defaults will be used.
-dim: [length] [width] [height] This sets the dimensions for the quarry
-invert: [t/f] If true, quarry will be inverted (go up instead of down)
-rednet: [t/f] If true and you have a wireless modem on the turtle, will attempt to make a rednet connection for sending important information to a screen
-restore / -resume: If your quarry stopped in the middle of its run, use this to resume at the point where the turtle was. Not guarenteed to work properly. For more accurate location finding, check out the -GPS parameter
-autoResume / autoRestore: Turtle will automatically resume if stopped. Replaces startup
-oreQuarry: [t/f] If true, the turtle will use ore quarry mode. It will not mine the blocks that are placed in the turtle initially. So if you put in stone, it will ignore stone blocks and only mine ores.
-oreQuarry: [t/f] If you are using a newer version of CC, you won't have to put in any compare blocks. (CC 1.64+)
-blacklist: [file name] If using oreQuarry, this is the blacklist file it will read. Example --
  minecraft:stone
  minecraft:sand
  ThermalExpansion:Sponge
  ThermalFoundation:Storage
  
  Note: If you have bspkrsCore, look 
  for "UniqueNames.txt" in your config
-file: [file name] Will load a file of parameters. One parameter per line. # is a comment line (See the forum thread for more detailed directions)
-atChest: [force] This is for use with "-restore," this will tell the restarting turtle that it is at its home chest, so that if it had gotten lost, it now knows where it is.
-doRefuel: [t/f] If true, the turtle will refuel itself with coal and planks it finds on its mining run
-doCheckFuel: [t/f] If you for some reason don't want the program to check fuel usage, set to false. This is honestly a hold-over from when the refueling algorithm was awful...
-overfuel: [number] When fuel is below required, fuel usage is multiplied by this. Large numbers permit more quarries without refueling
-fuelMultiplier: [number] See overfuel
-uniqueExtras: [number] The expected number of slots filled with low-stacking items like ore. Higher numbers request more fuel.
-maxFuel: [number] How much the turtle will fuel to max (limited by turtle in most cases)
-chest: [side] This specifies what side the chest at the end will be on. You can say "top", "bottom", "front", "left", or "right"
-enderChest: [slot] This one is special. If you use "-enderChest true" then it will use an enderChest in the default slot. However, you can also do "-enderChest [slot]" then it will take the ender chest from whatever slot you tell it to. Like 7... or 14... or whatever.
-fuelChest: [slot] See the above, but for a fueling chest. Reccommend use with -maxFuel and -doCheckFuel false
-lava: [slot] If using an oreQuarry, will fill itself with lava it finds to maxFuel
-lavaBuffer: [number] The amount of fuel below maxFuel the turtle will wait for before using lava again
-GPS: [force] If you use "-GPS" and there is a GPS network, then the turtle will record its first two positions to precisly calculate its position if it has to restart. This will only take two GPS readings
-quad: [t/f] This forces the use of GPS. Make sure you have a network set up. This will request to be refueled by a quadrotor from Lyqyd's mod if the turtle is out of fuel
-quadTimeout: [number] The amount of time the turtle will wait for a quadRotor
-sendChannel: [number] This is what channel your turtle will send rednet messages on
-receiveChannel: [number] This is what channel your turtle will receive rednet messages on
-legacyRednet: [t/f] Check true if using 1.4.7
-startY: [current Y coord] Randomly encountering bedrock? This is the parameter for you! Just give it what y coordinate you are at right now. If it is not within bedrock range, it will never say it found bedrock
-startupRename: [file name] What to rename any existing startup to.
-startupName: [file name] What the turtle will save its startup file to.
-extraDropItems: [force] If oreQuarry then this will prompt the user for extra items to drop, but not compare to (like cobblestone)
-dumpCompareItems: [t/f] If oreQuarry and this is true, the turtle will dump off compare blocks instead of storing them in a chest
-oldOreQuarry: [t/f] If you are using new CC versions, you can use this to use the old oreQuarry.
-compareChest: [slot] If using oldOreQuarry, this will allow you to check for dungeon chests and suck from them.
-frontChest: [t/f] If using oreQuarry/oldOreQuarry, this will check in front of itself for chests as well.
-left: [t/f] If true, turtle will quarry to the left instead of the right
-maxTries: [number] This is the number of times the turtle will try to dig before deciding its run into bedrock.
-forcePrompt: [parameter] Whatever parameter you specify, it will always prompt you, like it does now for invert and dim.
-logging: [t/f] If true, will record information about its mining run in a folder at the end of the mining run
-preciseTotals: [t/f] If true (and turtle.inspect exists), it will log a detailed record of every block the turtle mines and send it over rednet
-doBackup: [t/f] If false, will not back up important information and cannot restore, but will not make an annoying file (Actually I don't really know why anyone would use this...)
-saveFile: [word] This is what the backup file will be called
-logFolder: [word] The folder that quarry logs will be stored in
-logExtension: [word] The extension given to each quarry log (e.g. ".txt" or ".notepad" or whatever)
-keepOpen: [number] This is the number of the slots the turtle will make sure are open. It will check every time it mines
-careAboutResources: [t/f] Who cares about the materials! If set to false, it will just keep mining when its inventory is full
-startDown: [number] If you set this, the turtle will go down this many blocks from the start before starting its quarry
  =
  C _ |
      |
      |
      |
      |_ _ _ _ >
-flatBedrock: [t/f] If true, turtle will find bedrock and "zero" itself so it ends on bedrock level
-promptAll: This is the opposite of -Default, it prompts for everything
-listParams: This will list out all your selected parameters and end quarry. Good for testing
-manualPos: [xPos] [zPos] [yPos] [facing] This is for advanced use. If the server reset when the turtle was in the middle of a 100x100x100 quarry, fear not, you can now manually set the position of the turtle. yPos is always positive. The turtle's starting position is 0, 1, 1, 0. Facing is measured 0 - 3. 0 is forward, and it progresses clockwise. Example- "-manualPos 65 30 30 2"
-version: Displays the current quarry version and stops the program
-help: Thats what this is :D
Examples: Everything below is examples and tips for use
Important Note:
  None of the above parameters are necessary. They all have default values, and the above are just if you want to change them.
Examples [1]:
  Want to just start a quarry from the interface, without going through menus? It's easy! Just use some parameters. Assume you called the program "quarry." To start a 10x6x3 quarry, you just type in "quarry -dim 10 6 3 -default".
  You just told it to start a quarry with dimensions 10x6x3, and "-default" means it won't prompt you about invert or rednet. Wasn't that easy?
Examples [2]:
  Okay, so you've got the basics of this now, so if you want, you can type in really long strings of stuff to make the quarry do exactly what you want. Now, say you want a 40x20x9, but you want it to go down to diamond level, and you're on the surface (at y = 64). You also want it to send rednet messages to your computer so you can see how its doing.
Examples [2] [cont.]:
  Oh yeah! You also want it to use an ender chest in slot 12 and restart if the server crashes. Yeah, you can do that. You would type
  "quarry -dim 40x20x9 -invert false -startDown 45 -rednet true -enderChest 12 -restore"
  BAM. Now you can just let that turtle do it's thing
Tips:
  The order of the parameters doesn't matter. "quarry -invert false -rednet true" is the same as "quarry -rednet true -invert false"
  
  Capitalization doesn't matter. "quarry -iNVErt FALSe" does the same thing as "quarry -invert false"
Tips [cont.]:
  For [t/f] parameters, you can also use "yes" and "no" so "quarry -invert yes"
  
  For [t/f] parameters, it only cares about the first letter. So you can use "quarry -invert t" or "quarry -invert y"
Tips [cont.]:
  If you are playing with fuel turned off, the program will automatically change settings for you so you don't have to :D
  
  If you want, you can load this program onto a computer, and use "quarry -help" so you can have help with the parameters whenever you want.
Internal Config:
  At the top of this program is an internal configuration file. If there is some setup that you use all the time, you can just change the config value at the top and run "quarry -default" for a quick setup.
  
  You can also use this if there are settings that you don't like the default value of.
