I highly recommend the latest Hobo book:
http://hobocentral.net/manual/books - walks you through and explains most
of what you are asking. It's not Rails 4 or Hobo 2.x yet, but most of the
things still apply. Also, go through the Agility tutorial first, if you
haven't yet.
But yes, you are correct, basically Hobo tries to look for an action page
in the app/views directory first, and then if it does not find that,
pretends it contained an "<#{action name}-page>" call (e.g. for #show, a
"<show-page>" call), then executes that.
So to customize behaviour, you can either put your logic inside the
<show-page> tag itself (somewhere in a tag definition file under
app/views/taglibs), or you can put your logic into
"(app/views/#{controllername}/#{actionname}.dryml" as DRYML custom view.
Either way, can do whatever you want, draw on as much or as little
functionality as you want. If you put "Hello World!" and nothing else into
that .dryml file, then that's what the action will return to the browser.
But usually it contains a call to the respective <#{actionname}-page> tag
(e.g. for a #show action <show-page>, for #edit <edit-page>, for #foobar
<foobar-page>, etc.), just strongly parameterized inside.
