sofar i have managed to get arround this by repeatedly retrieving and storing data from

commandLogger("/scoreboard players tag @e[type=" .. targetentity .. ",tag=!scanned,c=1] add scanning")
_,result = commandLogger("/entitydata @e[type=" .. targetentity .. ",tag=scanning] {}")
commandLogger("/scoreboard players tag @e[tag=scanning] add scanned")
commandLogger("/scoreboard players tag @e[tag=scanning] remove scanning")

but this is far from optimal

a mod that uses entities as its marker for where it should spawn special mobs isn't working so i decided to write a script that does the spawning for it, unfortunately i need to set nbt flags for the spawned entities to tell them where the thing they were spawned from is. i have everything working but i am having problems when it comes to getting the nbt of more than one entity as here is the thngs i have found

debug card unclaimed - dosn't return required text

debug card claimed - works great as long as i'm OK with it stopping if i'm offline(which i'm not)

command_block - only returns text for last entity found

also im using while loops instead of for loops because for some reason they weren't executing more than once

command execution code:

local function commandLogger(command)
  writelog("executed command: " .. command)
  commandBlock.setCommand(command)
  local numb,result = commandBlock.executeCommand()
  writelog(tostring(numb) .. tostring(result))
  return numb,result
end

entity counting and cord getting:

local function coordget(rawinfo)
--print(rawinfo)
  local entities = {}
  local segmented = string.gsub(rawinfo,","," ")
  local seperated = text.tokenize(segmented)
  local count = 0
  local i = 1
  while i <= #seperated do
    if seperated[i] == "The" then count = count + 1 end
    if string.sub(seperated[i],1,2) == "x:" then 
      entities[count] = {}
      entities[count][1] = string.sub(seperated[i],3)
    end
    if string.sub(seperated[i],1,2) == "y:" then entities[count][2] = string.sub(seperated[i],3) end
    if string.sub(seperated[i],1,2) == "z:" then 
      entities[count][3] = string.sub(seperated[i],3)
      writelog("found entity at ".. entities[count][1] .." ".. entities[count][2]  .." ".. entities[count][3])
    end
    i = i+1
  end
  writelog("found ".. tostring(#entities))
  return entities
end

spawning code:

local function fairy_circle()
if config[2] then
  commandLogger("/scoreboard players set @e[type=roots:fairy_circle] fairycount 0")
  writelog("fairycount zeroed")
  os.sleep(0.1)
  commandLogger("/execute @e[type=roots:fairy] ~ ~ ~ /scoreboard players add @e[type=roots:fairy_circle,r=20] fairycount 1")
  writelog("counted fairy's")
  os.sleep(0.1)
	local _,raw = commandLogger("/entitydata @e[type=roots:fairy_circle] {}")
	os.sleep(0.1)
	if raw ~= nil then
	  local entities = coordget(raw)
	  local i=1
	  while i <= #entities do
	    writelog("starting fairy spawn for pool: " .. tostring(#entities) .. " at: ".. entities[i][1] .." ".. entities[i][2]  .." ".. entities[i][3])
        local rand = math.random(3)
	    local nbt = "{variant:".. rand ..",spawnX:".. entities[i][1] ..",spawnY:".. entities[i][2] ..",spawnZ:".. entities[i][3] .."}"
	    writelog("summoning fairy with nbt: " .. nbt)
	    commandLogger("/execute @e[score_fairycount=50] ~ ~ ~ /summon roots:fairy ~ ~ ~ " .. nbt)
    	i=i+1
	  end
	end
  end
end

here is the full script if anybody needs it:

autorun.lua

the world.getMetadata() function from the debug card seems to be giving a string like minecraft:oak_stairs[facing=east,half=bottom,shape=straight] instead of a number which is what setBlock claims to need.

github of my project is at https://github.com/hpf3/open-computers-structure-scanner i am currently working on its construction componnent(though i will most likely have to make changes to its scanning too)
