10559 :: 2 questions on StringStream

• oyster (orginal) [2023-10-20T10:45:56+02:00] view original

  I have read https://nim-lang.org/docs/streams.html but I think I found nothing useful for my question

  1. question 1, how to create StringStream for writing?

  what I have tried

  
  fOut = newStringStream("", fmWrite)
  Run

  but it is obviously wrong

  2. question 2, how to the contents in StringStream to a file?

  Thanks

  Iirc, StringStreams are read-write by default.

  readStr also requires an argument for how many characters you want to read, you probably want readAll. Though, StringStreams also have a data field for the content contained within.
