Is it possible to get flashing progress (percentage)?

[altjz]

First. Many thanks to this great library/tool. It saves a lot of time.
And forgive me the issue template doesn't fit the feature request.

Feature request

Provide flashing progress.

Expected behavior

may be add progress callback here

var Avrgirl = require('avrgirl-arduino');

var avrgirl = new Avrgirl({
  board: 'uno'
});

avrgirl.flash('Blink.cpp.hex', function (error) {
  if (error) {
    console.error(error);
  } else {
    console.info('done.');
  }
}, function(progress) { // progress here
    console.log(progress);
});

Description

I used avrdude to flash the board before.
Avrdude doesn't have the progress, But I can detect the output string with symbol '#' to calculate progress.
The information of debug mode is not enough. Any way to get progress on avrgirl-arduino ?

Current debug mode

found nano on port /dev/cu.usbserial-A50285BI
connected
reset complete.
flashing, please wait...
flash complete.

avrdude done.  Thank you.

Hi @altjz thanks for opening this issue.

Progress reporting is a feature I have wanted to implement for a long time now. After this issue was opened by you I started working on this. I'll set up a milestone and reference this issue soon so you can track progress on this feature. It is a big job to implement for a variety of reasons, but we're getting there slowly 😄

Would you be interested in helping test this feature once it's ready?

Thanks again

[altjz]

Hi @noopkat, thanks for response.
I can't wait to test this feature! Let me know once it's ready! 😃

Hi @noopkat, what is the status of this ? Is there any work that can be contributed?

[noopkat]

@s00500 I'm about halfway through implementing this but I want to prioritize the work on my end to get it done asap. Sorry it has taken so long it's been a lot of work.
