Enable customization of backtrace start/end banners

[dandee]

I'd like to set my own backtrace start/end banners or silence them completely. So instead of seeing this for example:

[2020-07-16 22:31:16.718] [info] ****************** Backtrace Start ******************
[2020-07-16 22:31:16.719] [info] Some log
[2020-07-16 22:31:16.721] [info] ****************** Backtrace End ********************
[2020-07-16 22:31:16.723] [info] App is doing well

I'd like to see this:

[2020-07-16 22:31:16.719] [info] Some log
[2020-07-16 22:31:16.723] [info] App is doing well

or this:

[2020-07-16 22:31:16.718] [info] Hello world!
[2020-07-16 22:31:16.719] [info] Some log
[2020-07-16 22:31:16.721] [info] and after the intermission now this:
[2020-07-16 22:31:16.723] [info] App is doing well

Is it okay to keep the banners in a text file? You can edit the file whenever you want to change the banners. Or are you looking for some other way?

[dandee]

The thing is that I've got a custom log sink that implements a custom GUI control. Due to its nature GUI controls are initialized much later that the application startup but I'd like to keep all logs presented in that GUI Log Control. Now: if there are backtraces present then the banners wouldn't bother me much (still, I'd like to customize them) BUT when there are no backtraces the banners are still present in the output making it a bit ugly (and possibly confusing for customers):

As for storing banners in a text file: I'd avoid that because that file would become an application resource, triggering all resource related issues (macOS bundle, embedded systems, etc.)

Interesting to know that someone is actually using the backtrace feature. I am planning to remove it in v2.x due to lack of interest..

That should be fine but I just wanted to avoid recompilation everytime we change banners.

I think it'd be a step back in offered functionality. Not everything is a direct console application. You can have embedded system with sink configured to output through serial link which could mean that you'd lose traces emitted before client console connects to that link, etc.

@dandee I think the ring buffer sink would be a good alternative to achieve this.

Fair enough! Thanks!
