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')

Functions
- create ()
-
create a file-like object which can be used to construct a string.
The resulting object has an extra
value()method for retrieving the string value. Implements file:write,file:seek,file:lines, plus an extrawritefmethod which works like utils.printf.Usage:
f = create(); f:write('hello, dolly\n'); print(f:value())
- open (s)
-
