4437 :: Nim in Action parallel_counts, readBuffer, and readChar

• sdwfrost (orginal) [2018-12-06T12:09:27+01:00] view original

  Dear All,

  I'm trying to get my head around modifying the parallel_counts example in Ch 6 of Nim in Action [https://github.com/dom96/nim-in-action-code/blob/master/Chapter6/WikipediaStats/parallel_counts.nim] to use readBuffer rather than readChar, so that ultimately it can read in the gzipped Wikipedia file rather than the decompressed one.

  1. Do I have to use a fixed size array[chunkSize, char] for the buffer (which means that I have to set chunk size at compile time), or just pass addr buffer to readBuffer?
  2. Given that readBuffer doesn't have the len parameter of readChar, how do I read in the required data?
