Return Key

Create a special key for returning the value when parsing

• Proposal Status: wip

• Issue Number: 245

• Proposal Doc: return-key.md

Overview

Blocked by return-hook

Currently when a declarative hook is called with an exec, the entire context is parsed with a special field for returning the appropriate value (return) being used to specify what the result is of that parsing.

This proposal would modify the parsing behaviour so that special keys can be used to indicate whether a variable is returned.

Examples

Normal parsing

foo: bar

return->: return {{foo}}

Macros

foo: bar

return->: return {{foo}}

Then move to using return hook.

foo: bar

tmp:

  ->: return {{foo}}
