Really? A full-fledge rockspec for a one file, self-contained module? Oh, my… :D

You are welcome.

While we are at it, I suspect that the semantic of read( number ) is slightly off…

For example:

print( stringio.open( 'foobar' ):read( -3 ) )

> foob

Perhaps a negative size should raise an exception or something, no?

Yes, it's rather convenient in various scenario.


P.S.

FWIW, I wrote my own in the meantime -with no doubts its very own set of bugs- until we can settle on one foolproof implementation:

http://dev.alt.textdrive.com/browser/Mail/StringIO.lua#L83

Usage example:

for aLine in StringIO( aString ):lines() do
  aCount = aCount + 1
  print( aCount, aLine )
end
