Yeah ... I'm Totally Lost In My Mind (fs.open(), Write Table And Cie ...)

event, Key = os.pullEvent("key")			 <-- this event is in a parallel.waitForAny
	LxPos, LyPos = term.getCursorPos()								
	RLettre = fs.open(saves.."/"..tostring(ficherLettre),"r")		  <-- read your current save file
	WLettre = fs.open(saves.."/"..tostring(ficherLettre),"w")   <-- ready to write
	dLxPos, dLyPos = LxPos, LyPos			  <-- LxPos = 1st Pos get, prefix "L" for "Lettre", "dL" for debugLettre
	  debugLettre()				 <-- [1]
	WLettre.write([LxPos,LyPos,Key,color])	<-- write the lettre with coordinates and color code on your file
	Rlettre.read(saves/tostring(ficherLettre))   <--[[
	  for i, lettre, in ipairs(fichierLettre) do									  
		term.setCursorPos(lettre[1],lettre[2])	 read your file and rewrite it on your screen imediatly.
		term.setTextColor(lettre[4])												
		term.write(lettre[3])															  
	  end			]]--
	term.setCursorPos(LxPos+1,LyPos+1)							   <-- set the cursor on the next position, like for real
	Rlettre.close()																	 <-- close file
	Wlettre.close()

When i was think on the program, was annoyed by the idea on: "if you write a new letter where there's already one, it will erase it, or worse, you'll get both ...". So i imagined
a function where if you write a lettre where there's already one, it will decal it until every letters got their own place. I know that a huge part of this function is really bad writted ... these are just my notes to keep ideas. ]]

  function debugLettre()
	if string.match([dLxPos,dLyPos,...,..]) == true then		   <-- the aim of this line is to verrify if an "old" letter is in the same place of the "new" wanted one, if true it does:			
	  decalLettre = {string.match...}										 <-- take the "old" letter
	  dLxPos = dLxPos + 1													  <-- modify its position (yeah, i'll add the same thing for yPos later ;)/>/>/>/>/>/>)
	  WLettre.write([dLxPos, dLyPos, ..., ..])									 <-- write the "old" letter in its new position (virtual) in the [b][u]same[/u][/b] place in the file
	end
	if string.match([dLxPos, dLyPos, ..., ..], <---) then			 <-- check if the "new old" letter doesn't attempt to write over another letter by checking from the end of file [2]
	  debugLettre(dLxPos, dLyPos)										 <-- if true ... do debugLettre() again, until (as said before) each letter a its own place
	end
  end
