Created Essence Tracker of AE2 storage, displays on monitors that are connected

[toottootx]

ME Bridge is needed to interact with AE2 system.

I am new to the modpack so any critiques or suggestions are welcome. Feel free to use it and expand it however you like, would love to see what people might do with it.

local me = peripheral.find("me_bridge")
if not me then error("ME bridge not found") end

local monitors = { peripheral.find("monitor") } 
local COLS = 3 

local function setColor(mon, count)
  if count < 1000 then
    mon.setTextColor(colors.red)
  elseif count < 5000 then
    mon.setTextColor(colors.orange)
  elseif count < 10000 then
    mon.setTextColor(colors.yellow)
  elseif count < 50000 then
    mon.setTextColor(colors.green)
  elseif count < 100000 then
    mon.setTextColor(colors.cyan)
  elseif count < 500000 then
    mon.setTextColor(colors.blue)
  elseif count < 1000000 then
    mon.setTextColor(colors.purple)
  else mon.setTextColor(colors.pink)
  end
end

local function cleanName(name)
  name = name:gsub("mysticalagriculture:", "")
  name = name:gsub("mysticalagradditions:", "")
  name = name:gsub("_essence:", "")
  name = name:gsub("_", " ")
  return name
end

local function formatLine(name, count)
  return string.format("%-15s %3s", name, count)
end

local function formatNumber(n)
  local s = tostring(n)
  return s:reverse():gsub("(%d%d%d)", "%1,"):reverse():gsub("^,", "")
end

local function drawGrid(mon, items)
  mon.clear()

  local w, h = mon.getSize()
  local cols = COLS
  local colWidth = math.floor(w / cols)

  local x, y = 1, 1
  local col = 0

  for _, item in ipairs(items) do
    setColor(mon, item.count)

    local text = formatLine(cleanName(item.name), formatNumber(item.count))

    mon.setCursorPos(x, y)
    mon.write(text)
    col = col + 1

    x = x + colWidth

    if col >= COLS then
      col = 0
      x = 1
      y = y + 1
    end
    if y > h then break end
  end
end

      table.insert(items, item)
    end
  end

  -- sort
  table.sort(items, function(a, b)
    return(a.count or 0) > (b.count or 0)
  end)

  -- format
  for _, mon in pairs(monitors) do
    mon.setTextScale(1.4)
    drawGrid(mon, items)
  end
  sleep(5)
