Did you repost this? I'm pretty sure not long ago there was a identical thread that had a few replies, but then got deleted.
Plus, I think i've seen this before. I can't recall the name to it, but I remember something like it.

Always have inventory crafted.
Purge unwanted items from the system (the chest in the video can be replaced with a trashcan).
Assemblers are optional (as the turtle can craft the items).

The turtle must be equipped with a crafting table and duck antenna (open peripherals) in order to craft items.

Does this OS support color theming? White text on blue background doesn't look too stellar.

Yes, you can add a file named ui.theme in the /config folder. Here is an autumn theme example:

-- Copy to /config/ui.theme to enable
{
  Button = {
	backgroundFocusColor = colors.orange,
	focusIndicator = '*',
  },
  Grid = {
	textColor = colors.white,
	backgroundColor = colors.gray,
	textSelectedColor = colors.black,
	backgroundSelectedColor = colors.orange,
	headerBackgroundColor = colors.yellow,
	headerTextColor = colors.black,
	unfocusedTextSelectedColor = colors.yellow,
	focusIndicator = '*',
  },
  GridLayout = {
	textColor = colors.white,
	backgroundColor = colors.black,
  },
  MenuBar = {
	backgroundColor = colors.lightGray,
  },
  StatusBar = {
	textColor = colors.brown,
	backgroundColor = colors.lightGray,
  },
  TabBar = {
	selectedBackgroundColor = colors.brown,
	focusBackgroundColor = colors.green,
  },
  TitleBar = {
	backgroundColor = colors.brown,
  },
  ViewportWindow = {
	backgroundColor = colors.brown,
  },
}

You can also selectively theme applications by adding a theme section in the associated application config file.

[LDDestroier]

Cool. I'll make myself a gray/white/yellow theme.

Also, if you didn't check your PM, I changed contextualGet() to std.contextualGet(). If the Discover section of the Opus store is to work, please change it. I changed the name just so I could keep all the STD variables contained.
A few other internal values were put in table 'std', but they aren't referenced by the store pages, do it shouldn't be a big deal.

Hi!

Amazing job on the OpusOS Keplar! I love it how when apps crash they do it independent of the Operating System. There are two bugs I have encountered and a suggestion I would like you to implement/fix.
I have organized this reply in a easy to read format as best I could.

BUGS:

• turtle follow program crashes because GPS system doesn't work. (I know how the follow program should work, I watched your video)
  
• whenever I run the 'startup' file within OpusOS it creates another copy inception, when I close the inception it leaves a irremovable residue in the tab menu, I would like this to be fixed please .

REQUEST:
I would like a way to view a functions potential arguments, or a way to view the 'guts' of the function. FOR EXAMPLE; MineChem has bad error handling so it spits out uninterpretable errors instead of giving me its usage. If this is impossible that is ok to my knowledge there is no way to do this.

[Kepler]

Thanks for the feedback. Please let know if you find anything else.

I would say this works as expected. The script tab is left open on the turtle with the error message "No GPS found".

I'm not sure what use it would be to run the OS within the OS. There's probably more problems that would occur other than the tab issue.

This type of error checking in functions would really bloat the source. I would suggest using the trace program from Apemanzilla if you are having trouble tracking down errors. You can also reference the source code in Git as an easy way to view the functions and arguments.

Again, thanks for the feedback...

Very good OS

[ZapowGaming]

Nice OS!

Also just for fun, I tried downloading this on a regular computer (not advanced) to see what would happen. It downloaded okay, but once it rebooted so it could be used, it was unusable because the mouse didn't work lol. It was cool seeing it in black and white though.

Thanks !

It's not very easy to use without a mouse, but it is usable. Here's some keystrokes you can use:

Control-o: Show Overview
Control-tab: Next tab / process

Within Overview (opening screen):
s = shell
l = lua

Any application:
Tab or arrow keys to navigate
Control-enter: restart application
Control-d: show debug tab

I am quite the noob to computercraft and I gotta know how you got that turtle set up.

The turtles track their current position and facing as they move around (by checking whether the movement succeeded).
This information can be used for dynamic GPS hosts (which may be what's used for the "follow" command), as well as instructing the turtle where to go.
All it takes at setup is to feed the turtle its coordinates (manually or through GPS) and facing (manually or by moving the turtle and using GPS again).

[Kepler]

Most of the turtle movement code is in another API. But here is the following code:

Spoiler

local function follow(id)
  require = requireInjector(getfenv(1))
  local Socket = require('socket')
  local Point  = require('point')
  local Event  = require('event')
  turtle.status = 'follow ' .. id
  if not turtle.enableGPS() then
	error('turtle: No GPS found')
  end
  local socket = Socket.connect(id, 161)
  if not socket then
	error('turtle: Unable to connect to ' .. id)
	return
  end
  local lastPoint
  local following = false
  Event.on('turtle_follow', function(_, pt)
	local pts = {
	  { x = pt.x + 2, z = pt.z,	 y = pt.y },
	  { x = pt.x - 2, z = pt.z,	 y = pt.y },
	  { x = pt.x,	 z = pt.z + 2, y = pt.y },
	  { x = pt.x,	 z = pt.z - 2, y = pt.y },
	}
	local cpt = Point.closest(turtle.point, pts)
	local blocks = { }
	local function addBlocks(tpt)
	  table.insert(blocks, tpt)
	  local apts = Point.adjacentPoints(tpt)
	  for _,apt in pairs(apts) do
		table.insert(blocks, apt)
	  end
	end
	-- don't run into player
	addBlocks(pt)
	addBlocks({ x = pt.x, z = pt.z, y = pt.y + 1 })
	if turtle.pathfind(cpt, blocks) then
	  turtle.headTowards(pt)
	end
	following = false
  end)
  Event.onInterval(.5, function()
	local function getRemotePoint()
	  if not turtle.abort then
		if socket:write({ type = 'gps' }) then
		  return socket:read(3)
		end
	  end
	end
	-- sometimes gps will fail if moving
	local pt, d
	for i = 1, 3 do
	  pt, d = getRemotePoint()
	  if pt then
		break
	  end
	  os.sleep(.5)
	end
	if not pt or turtle.abort then
	  error('Did not receive GPS location')
	end
	if not lastPoint or (lastPoint.x ~= pt.x or lastPoint.y ~= pt.y or lastPoint.z ~= pt.z) then
	  if following then
		turtle.abort = true
		while following do
		  os.sleep(.1)
		end
		turtle.abort = false
	  end
	  -- check if gps is inaccurate (player moving too fast)
	  if d < Point.pythagoreanDistance(turtle.point, pt) + 10 then
		lastPoint = Point.copy(pt)
		following = true
		os.queueEvent('turtle_follow', pt)
	  end
	end
  end)
  Event.on('turtle_abort', function()
	Event.exitPullEvents()
  end)
  Event.pullEvents()
  socket:close()
  return true
end
local s, m = turtle.run(function() follow({COMPUTER_ID}) end)
if not s and m then
  error(m)
end

[kreezxil]

I'm getting a crash when installing the operating system.

After hitting next on the "Download and Install" screen, it red lines the text "Expected String" and then only gives me an ">exit" option.



I am using the Computality mod on 1.12 build 2443.
