Detect current`tinytheme`/modified `tpar` settings

[katrinabrock]

Hi,

I'm writing a package with plotting functionality based on tinyplot. I would like to set a custom default theme. So..if the user has not set any tinyplot theme, and they run my plotting function, my theme will be used. However, I would like to set it up such that if the user has configured a theme themselves (or set tpar in some other way), I don't trample it. Is there a way to achieve this with exported functions?

It looks like is.null(tinyplot:::get_environment_variable(".tpar_hooks")) will tell me if a theme is set or not so at least for the theme case, I could check this and apply my theme only if a theme is not already set.

I'm also seeing that tinyplot:::init_tpar sets the default tpar so maybe I could extract them in some way and then compare to current tpar to see if the user has changed anything away from the default?

Is there a recommended way to achieve this?

Naturally, as soon as I posted this I found a solution, at least for the theme case: tinyplot::tpar("tinytheme")

Still curious whether this is the recommended approach and if there is a way to detect which, if any, tpar have been user defined.
