Great, I'll give it a go then :)
The type of progress output I'm handling is that of a fixed-width bar that
fills up with a certain character (e.g. '*' or '#"). Just like BitBake's own
output.
Moreover I want to generalize it to support multiple weighted stages, e.g.:
STAGE 1: message
[######################]
STAGE 2: message 2
[############ ]
To the progress handler, a stage generally looks like:
[ ]
[# ]
[## ]
[### ]
… etc.
Will also try to handle the case of an embedded spinner, e.g.: | / - \ -
Thanks again for the encouragement :)
Chris

I see no problem in adding it; I am curious about your custom handler as well
