Re: read number from ascii (text) file: scanf-like functionality?

If your string and the extracted results fit in your memory you can use the 
splitWhiteSpace iterator: 
[https://nim-lang.org/docs/strutils.html#splitWhitespace.i,string,int](https://nim-lang.org/docs/strutils.html#splitWhitespace.i,string,int)

Otherwise write a simple parser using streams and readFloat32/readFloat64 
([https://nim-lang.org/docs/streams.html#readFloat32%2CStream](https://nim-lang.org/docs/streams.html#readFloat32%2CStream))
 and discarding the space/tabs/newline in-between.

In pseudocode (I may have missed something).
    
    
    import streams
    
    proc myReader*(path: string): seq[float32] =
      let stream = newFileStream(path, mode = fmRead)
      defer: stream.close()
      
      while not stream.atEnd():
        result.add s.readFloat32()
        discard s.readChar
    
    
    Run
