Loading changes detected in scratch.u.
I found and typechecked these definitions in scratch.u. If you
do an `add` or `update`, here's how your codebase would
change:
⍟ These new definitions are ok to `add`:
even : Nat -> Boolean
is2even : 'Boolean
odd : Nat -> Boolean
it errors if there isn't a previous run
scratch/main> add.run foo
⚠️
There is no previous evaluation to save. Use `run` to evaluate
something before attempting to save it.
scratch/main> run is2even
true
it errors if the desired result name conflicts with a name in the unison file
scratch/main> add.run is2even
⚠️
Cannot save the last run result into `is2even` because that
name conflicts with a name in the scratch file.
otherwise, the result is successfully persisted
scratch/main> add.run foo.bar.baz
⍟ I've added these definitions:
foo.bar.baz : Boolean
scratch/main> view foo.bar.baz
foo.bar.baz : Boolean
foo.bar.baz = true
It resolves references within the unison file
