---Reading and writing strings using file-like objects.
---
---```lua
---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')
---```

---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 extra
---`writef` method which works like `utils.printf`.
---@return pl.StringIOWriter
---@nodiscard
---
---Usage:
---
---```lua
---f = stringio.create()
---f:write('hello, dolly\n')
---print(f:value())
---```
function stringio.create() end

---create a file-like object for reading from a given string. Implements
---`file:read`.
---@param s string -- The input string.
---@return pl.StringIOReader
---@nodiscard
---
---Usage:
---
---```lua
---f = stringio.open '20 10'
---x,y = f:read ('*n','*n')
---assert(x == 20 and y == 10)
---```
function stringio.open(s) end
