What about a bar.clear()?

[stheine]

Hi,

on long-running jobs with a progress bar, I often have the need to print some extra log information in special situations.
as this interferes with the bar, I'd like the ability to completely clean out the bar, then print my log message, and then print the bar again in the next line.
currently, my workaround is:

bar.stop();
process.stdout.write('\x1b[1A \r'); // add enough blanks to clear out the bar
console.log('my log message');
bar.start(total, num);

I would rather hope for

bar.clear();
console.log('my log message');
...
bar.update(num); // this automatically draws the bar again on the next update

Regards
stheine

there are some events available to print your messages, just take a look into the docs

not sure what you're referring to. I find many options to tweak the format of the bar itself, but when I'm logging extra data, that can be multi-line/ JSON.stringify/ colored, so I don't know how I could put that into the bar, that's why I'm rather completely removing the bar, then print my log data, then redraw the bar below my log output.

see #85 #57
but this method is intended for simple logging, not for fancy formatting. and as you might see by reading the previous issues regarding this feature request...it's quite complicated for multibars...

ok, get your point. of course, my workaround only works for the single bar mode - and that's fine for me, as that's all I use here - but you'd also have to cover the multi bar mode (unless you'd only offer that for single bar).
thanks for the pointers.
