Caching formatted result from a log call

[jerome-trc]

I'm more than interested in using Quill for my project for the asynchronous formatting, but my application benefits from storing formatted log strings for display in an in-window Dear ImGui panel (not for my benefit, but that of the hypothetical user). Would there be a way to keep doing this - printing to cout, inserting a string to a vector, and writing to a file in one macro/call - using Quill without any hacky system stream intercepts/redirects? I haven't seen any tweak options in Quill.h or TweakMe.h or any mention of such a thing in the wiki.

Hello,

It is possible to implement custom handlers and register them.

Each logger can have multiple handlers attached.
And each handler can also have its own custom format.

If you would like a single LOG_ macro call to do all the 3 things listed above you have 2 options:

1. Implement a custom handler that does all handing inside (file/vector/console).
2. Use the existing console and file handlers and implement a custom handler to append to a vector.

I have pushed an example that is using option 2 here

Keep in mind that the vector in the example above is written by a backend worker thread. If you are having a different thread reading the vector to render it to the gui then you will have to use a mutex on the vector.

Let me know if you have any issues or any other questions

Works excellently. Thanks for the help.
