How to configure the public folder?

[nono]

Description

I'd like to use a custom public folder and I don't see a good way to do that. As a work-around, I have recoded Kemal.run, but it looks very hackish.

Steps to Reproduce

Kemal.run do |config|
  config.public_folder = "./web"
end

Expected behavior: Kemal serves static files from the web directory

Actual behavior: Kemal serves static files from the public directory

Reproduces how often: always

Additional Information

config.setup is called before yield config in Kemal.run, which means that changing the config in the block has no effect on how the config setup its handlers.

You can

Kemal.config.public_folder = "./web"
Kemal.run
