Is --progress stdout working?

[mbruel]

Hi, It seems to not work on my env... Am I doing something wrong?

~/Downloads/testNgPost$ ~/apps/ParPar/bin/parpar.js --version
0.3.1
~/Downloads/testNgPost$ ~/apps/ParPar/bin/parpar.js -s1M -r8% -m1024M --progress stdout -o test.par2 jdk-8u171-linux-x64.tar.gz > out.txt 2> err.txt
~/Downloads/testNgPost$ wc -l out.txt err.txt 
  0 out.txt
  4 err.txt
  4 total

In fact --progress none is also doing the same :\

What's the contents of err.txt?

[mbruel]

~/Downloads/testNgPost$ cat err.txt 
Multiply method used: Shuffle (256 bit), 8 threads
Generating 15 MiB recovery data (15 slices) from 182.05 MiB of data

PAR2 created. Time taken: 0.743 second(s)

There is no progress information, probably cause the file is too small and thus the generation too fast. Anyway I would expect to have all this text on stdout also. This is not errors. Could you do it?

There should always be progress output, as the 100% text is always written. wc -l counts newlines as opposed to lines, and the progress output never writes a newline, so perhaps you're thinking that there's no output on stdout. Try actually checking the size of out.txt itself, and if you open it, you may find the progress information there.

my out.txt is empty, not sure why... But it seems to work well if I use it with ngPost. Except I've still those 3 lines in stderr that are flagged as errors and thus displayed in red in ngPost GUI Could write all that in stdout too plz?

[animetosho]

my out.txt is empty, not sure why...

How are you checking that? Does du -b out.txt say the size is 0 bytes?

Except I've still those 3 lines in stderr that are flagged as errors

Use the -q flag.

[mbruel]

~/Downloads/testNgPost$ du -b out.txt 
2184    out.txt

but if I edit the file I don't see anything.... Is it cause you're using \r to rewrite on the same line ?

Use the -q flag.

Cool that's perfect! (using --progress stdout -q) I thought the -q would force --progress none and thus I wouldn't get any progress indication. That's what I understood from your description

       --progress            Progress indicator display, which can be either:
                                 none: disable progress output
                                 stderr: output a progress indicator to stderr
                                 stdout: output a progress indicator to stdout
                             Default is `stderr`, or `none` if `--quiet` is
                             specified.
  -q,  --quiet               Suppress information output. Errors will still be
                             displayed

It uses magic terminal sequences to clear the line. Terminal editors may have a bit of an issue dealing with them, though most good text editors shouldn't have any problems.

If you have a wording suggestion, I can consider it.

hum maybe adding something on the --quiet option.

-q,  --quiet               Suppress information output. Errors will still be
                             displayed. (Progress will still output if --progress is specified other than none)

Okay thanks, I've tweaked the text a little.
