Returning empty table?

--apis--
tPath = function( sFile )
  if string.sub( sFile, 0, 1) == '/' then
	sFile = ':' .. sFile
  end
  if string.sub(sFile, 0, 2) ~= ':/' then
	sFile = ':/' .. sFile
  end
  if string.sub(sFile, #sFile- 1, #sFile) ~= '/' then
	sFile = sFile .. '/'
  end
  local lastSlash = 0
  local folder = {}
  i=0
  while i ~= #sFile do
	if string.sub(sFile, i, i+1)=='/' then
	  table.insert(folder, string.sub(sFile, lastSlash, i+1))
	  lastSlash = i
	end
  i=i+1
  end
  return folder
end

--test file--
os.loadAPI('apis')
args = {...}
for n, string in ipairs( apis.tPath(args[1])) do
  print(string)
end

--command--
test main/test/somepath

args = {...}
for dir in args[1]:gmatch( "(.-)/" ) do
  print( dir )
end

Why not use string.gmatch?

args = {...}
for dir in args[1]:gmatch( "(.-)/" ) do
  print( dir )
end

This won't print the program name, but that's simple to get with string.match.

if string.sub( sFile, i, i+1 ) == '/' then

if string.sub( sFile, i, i )== '/' then
