enhancement idea

[YuxingW]

Recently I am using robotbackgroundlogger in my test and found below areas can be enhanced:

1. if background loggers are created in several places, they are not sharing the message queue for one thread, so it cannot aggregate all logs for one thread. This can be solved by using Singleton instance of background logger.
2. The BackgroundMessage output is unexpected and not compatible with MainThread output, actually we can use Message in loggerhelper.py directly.
   I made enhancement locally and it works well, would like to create a pull request for review, please see if it is okay.

Pull requests are always welcome. Unfortunately I don't have much time I could spend with this project, so I cannot make promises when it could be reviewed.

I was unable to check in my change to my branch:
c:\github\robotbackgroundlogger>git push --set-upstream origin yuxing_dev
Username for 'https://github.com': YuxingW
Password for 'https://YuxingW@github.com':
remote: Permission to robotframework/robotbackgroundlogger.git denied to YuxingW.

Can you please take a look? Thanks!

It seems you try to push into this repository. You need to create your own fork first. GitHub has good docs related to that. If you are totally new to GitHub, you can start by reading Robot Framework's contribution guidelines. They don't fully apply to this project, but most of the content is valid.

Thanks. I was able to create a pull request with the guideline.
It is a minor change, please help review.

Read this originally in a hurry. Here's what I think about the proposals after reading this again and looking PR #6 :

1. There should be separate issues and PRs about different enhancements.
2. I don't want to introduce singleton pattern here, at least not so that it is used by default and you cannot create individual instances. Adding a separate class method for that could be considered.
3. I don't understand your second problem.
4. As I've already commented, I don't really have time for this project.

Thanks.
For 2, I changed it to a get_instance classic method.
For 3, I attached a snapshot of my problem, the first thread log is printed in console instead of ouput.xml, can be solved by using logger and log_message.
