Is there any function similar to 'scanf' ?

  I think you need something like this keyboard which should do just what you require.

  I thing that str:match like str:match("value (%d+)") should be closest to scanf
  
  And about input, you could also wait a bit and text input will be available in next Gideros version.

  @ar2rsawseen , i can't find where str:match is. It isn't in reference manual or ultimate guide to Gideros. Can show where it is or could you supply a very simple example. For example , enter your name then it will output your name etc.

  match is part of the standard Lua string library - google "Lua string.match" - chances are @ar2rsawseen has str as a local reference to string.
  
  It might be worth picking up a copy of "Programming in Lua 2nd Ed" or "Beginning Lua Programming" - both are excellent references to the standard libs

  yes, just as @techdojo said. This is part of lua language library, completely not related to Gideros.

  You can read in numbers from a file like this:

  local fh=io.open("input.txt","r") x,y=fh:read("*number","*number") fh:close()

  This is similar to fscanf in C. Like fscanf, fh:read will skip past white space and newlines while looking for numbers.
