Is it possible to update the book.toml config in a preprocessor?

Hey team,

I'm working on a preprocessor where I'd like to update the book.toml in a preprocessor (compiling JS entry files) so that I can add additional properties to an HTML template that's not known ahead of time.

Is it possible to update a the book.toml from the PreprocessorContext?

It is not possible. There are other requests to be able to add additional files via a preprocessor (such as #1222), it might be good to add a comment there with your use case if you just need to add additional files.

Thanks for the comment, @ehuss

Not sure how to add an additional file to the index.html template without being able to modify the PreprocessorContext object.
