mount-point: auto link rewrite

[amitu]

If an app fifthtry.github.io/todos/ is mounted on amitu.com/todos/, and fifthtry.github.io/todos/index.ftd contains a link to fifthtry.github.io/todos/add-todo.ftd, what would it write?

If the fifthtry.github.io/todos/ was the main package, we could have used Direct Links:

-- ftd.text: add todo
link: /add-todo/

But fifthtry.github.io/todos/ is a dependency, so we can write, Dependency Link.

-- ftd.text: add todo
link: /-/fifthtry.github.io/todos/add-todo/

But since we are using mount-point, the URL should be Mount-Point Link:

-- ftd.text: add todo
link: /todos/add-todo/

So which one of this would be actually be present in fifthtry.github.io/todos/index.ftd?

Mount-Point Link is impossible answer here. And Direct Link will 404. So only option is Dependency Link, which will work both when fifthtry.github.io/todos/ is main package or a mounted dependency. But Mount Point Link is the best link from Clean URL perspective.

Auto Link Rewrite

Links can be present at only well known places in a document: a. markdown, b. http processor, c. link attribute and d. object for frontend.

We can find out the current document's context (is it main package or a dependency, and if dependency if it has a mount point associated), and automatically generate the Mount Point Link everywhere.
