Repeat node value in YAML

pagination:
    limit:
        default: 10
        min: 0
        max: 50
        current: default

The current node should have the same value as the default node? (in this case, 10). Is it possible to do that with YAML?

You can use an anchor for that, which is a token starting with & inserted before the scalar/mapping/sequence you want to "re-use". You "paste" it with an alias which is the same token preceded by a *.

pagination:
    limit:
        default: &def 10
        min: 0
        max: 50
        current: *def

(you can use default instead of def but you don't have to use the same string as the key whose value you put an anchor on)
