# What situations do we want to build docs in?
# All of these work independently and can be removed / commented out
# if you don't want oranda/mdbook running in that situation
on:
  # Check that a PR didn't break docs!
  #
  # Note that the "Deploy to Github Pages" step won't run in this mode,
  # so this won't have any side-effects. But it will tell you if a PR
  # completely broke oranda/mdbook. Sadly we don't provide previews (yet)!

  # Whenever something gets pushed to main, update the docs!
  # This is great for getting docs changes live without cutting a full release.
  #
  # Note that if you're using cargo-dist, this will "race" the Release workflow
  # that actually builds the Github Release that oranda tries to read (and
  # this will almost certainly complete first). As a result you will publish
  # docs for the latest commit but the oranda landing page won't know about
  # the latest release. The workflow_run trigger below will properly wait for
  # cargo-dist, and so this half-published state will only last for ~10 minutes.
  #
  # If you only want docs to update with releases, disable this, or change it to
  # a "release" branch. You can, of course, also manually trigger a workflow run
  # when you want the docs to update.

    branches:

  # Whenever a workflow called "Release" completes, update the docs!
  #
  # If you're using cargo-dist, this is recommended, as it will ensure that
  # oranda always sees the latest release right when it's available. Note
  # however that Github's UI is wonky when you use workflow_run, and won't
  # show this workflow as part of any commit. You have to go to the "actions"
  # tab for your repo to see this one running (the gh-pages deploy will also
  # only show up there).
