Allow custom progressbar consumers

[alexpeelman]

Hi, I extended this incredible useful tool a bit to allow any kind of consumer to print the progress bar. I need this to write the progress to an SLF4J log.

Hi Alex, thanks for this! Compatibility with SLF4J is of utmost importance -- I haven't got time to do it myself. Could you shed some light on how this extension would make it work with SLF4J, so that I could gain a better understanding of the underlying issue? You can paste a snippet here, or you could add a test that depends on SLF4J.

[alexpeelman]

Yes, you are completely right. I added a new DelegatingProgressBarConsumer and changed one of the tests so that it uses a SLF4J logger to print the progress bar.

The idea is that for each progress bar update the state is printed to the logger, without the carriage return.This logs the progress over time.

As an example

Thanks a lot @alexpeelman -- I'll review this when I got some time (hopefully this weekend).

[alexpeelman]

Hi just a small check if you are planning to review this any time soon ? No pressure just asking for an update here :)

[ctongfei]

Hooray! I merged this after some modifications to your code. See documentation at https://tongfei.me/progressbar/loggers/. Thanks @alexpeelman !

[alexpeelman]

Awesome ! Nice idea to introduce the renderer 👍
