5872 :: how to use Nimpretty ??

  Hello, I don't understand how to use Nimpretty. if I look the help, I got these (didn't find any doc online ) :

  nimpretty -h
  nimpretty - Nim Pretty Printer Version 0.2
    (c) 2017 Andreas Rumpf
  Usage:
    nimpretty [options] file.nim
  Options:
    --out:file            set the output file (default: overwrite the input file)
    --indent:N[=0]        set the number of spaces that is used for indentation
                          --indent:0 means autodetection (default behaviour)
    --maxLineLen:N        set the desired maximum line length (default: 80)
    --version             show the version
    --help                show this help
  Run

  so, I thought that it would simply save my file corrected with this simple command :

  nimpretty tst1.nim
  Run

  but it doesn't save it, even if I try to use the "out" option (with or without a name)..

  now, with a simple test file like that :

  var
    tmp1: string
    tmp2: string
  Run

  if I put 3 spaces for indentation on the "tmp1" line (and 2 on "tmp2" line), I got this :

  nimpretty tst1.nim
  C:\Data\nim\tst_time\tst1.nim(3, 3) Error: invalid indentation
  Run

  and this if I invert (2 spaces before tmp1 & 3 before tmp2) :

  nimpretty tst1.nim
  C:\Data\nim\tst_time\tst1.nim(3, 4) Error: invalid indentation
  Run

  and still got exactly the same results if I change the command line for :

  nimpretty --indent:2 tst1.nim
  Run

  so, why is the error always reported on line 3, even when adding "--indent:2" ???

  is Nimpretty still useful and how should I use it ? thanks..

  Well nimpretty cannot reformat wrong Nim code, that's impossible. It can reformat correct Nim code.

  well, ok.. if I put 3 spaces on both lines, it works. the code is formatted and saved.

  thanks, but I already found and read Nim documentation. that's Nimpretty for witch I didn't found documentation and I imagined it worked differently, my bad. my "example" was just an example to show something I didn't understand in the way nimpretty was working, not an example of my coding style. so I know now, thanks..
