@lygstate Hi, could you tell me how to reproduce this bug?

When you create your ProcessBar, you can configure width. jus like this: new ProgressBar(' download |:bar| :percent', { complete: '=' , incomplete: ' ' , width: 40 , total: 20 });

[lygstate]

var ProgressBar = require('progress');
var total = 1024;
var progressBar = new ProgressBar(' download |:bar| :percent :etas', { complete: '=' , incomplete: ' ' ,  total: total });
var end = 0;
var progressTimer = setInterval(function() {
  var p = end / total;
  end = end + 8;

  progressBar.update(p);
  if (end == total) {
    progressBar.terminate();
    process.exit(0)
  }
}, 10);

@lygstate Please use this to create your ProgressBar, you can set the width. var progressBar = new ProgressBar(' download |:bar| :percent :etas', { complete: '=' , incomplete: ' ' , total: 1024, width: 40 });

@lygstate

Did @wangyangkobe advice help you?

[Numbers11]

i can confirm this issue for win7 64bit, setting width isn't helping.

[pitaj]

It isn't happening for me with #tick, it may just be a problem with #update. Have you tried #tick?

[lbeschastny]

Probably, it's a problem of some particular TTY.

node-progress redraw its progress bar calling .cursorTo(0) and .clearLine(1) methods from node.js build-in Readline module, which are implemented with terminal escape sequences.

But I'm not absolutely sure that all Windows terminals support escape codes.

[lbeschastny]

It could also be caused by #116, but in this case problem should've been resolved by manually setting width.

[alallier]

I get the same thing in Windows 10, what happens is if the width is set too high or the console's width is too small it will print each tick as a new line. But if the width is set low enough and the console's width is wide enough it will print on one line screen shots below:

Which results in 4 different cases

1 Width 100 and console width wide:

• 

2 Width 500 and console width wide(same as 1):

• 

3 Width 100 and console width small:

• 

4 Width 500 and console width small:

• Same as 3

For some reason prepending the fmt string with \x1b[1G\x1b[2K (which does the same as calling .cursorTo(0) and .clearLine(0) methods from readline) solves the issue. I don't know why using the readline methods don't work but using escape codes work.
