YAML Anchors and References

This is a post to help me remind how YAML Anchors and References work.


In YAML you can make an Anchor:

- first_name: &me Robert

Now the Anchor me contains Robert. To refer to it, do something like this:

- first_name: &me Robert
  give_name: *me

The value for given_name has been set to Robert.

You can also anchor to a whole list item:

  - person: &me
    name: Robert
    family_name: de Bock

No you may refer to the me anchor:

  - person: *me

Now Robert has access.

Good to prevent dry.
