Sync API with block

[YusukeIwaki]

Simple description about the feature

Provide sync API with block, like playwright-python. (ref: https://playwright.dev/python/docs/navigations#asynchronous-navigation)

page.wait_for_navigation do
  page.click('#submit')
end

Usecase / Motivation

puppeteer-ruby provides async APIs.

await_all(
  page.async_wait_for_navigation,
  page.async_click('#submit'),
)

Async API would be familiar with JS users, but not so useful for Ruby users.
For example, async_click('#submit'), async_press('Enter') is not smart, not intuitive.
with_observing_something { click('#submit') } with_observing_something { press('#submit') } would be more useful for Ruby users, in such cases.
