Reading and writing strings using file-like objects.


f = stringio.open(text)
l1 = f:read()  -- read first line
n,m = f:read ('*n','*n') -- read two numbers
for line in f:lines() do print(line) end -- iterate over all lines
f = stringio.create()
f:write('hello')
f:write('dolly')
assert(f:value(),'hellodolly')
