partial.lenses - npm Package Versions

13.1.0

Obsoleted L.iftes and added L.ifElse and L.cond as the replacements for it. The motivation for the change is that formatting tools such as Prettier cannot produce readable layouts for combinators that use such non-trivial argument patterns. In cases where there is just a single predicate, use L.ifElse:

-L.iftes(predicate, consequent, alternative)
+L.ifElse(predicate, consequent, alternative)

In cases where there are multiple predicates, use L.cond:

-L.iftes(predicate1, consequent1,
-        predicate2, consequent2,
-        alternative)
+L.cond([predicate1, consequent1],
+       [predicate2, consequent2],
+       [alternative])

13.0.0

As discussed in issue #131, optics working on arrays, objects, and strings, no longer remove empty values by default. It appears that by default removal, on average, makes optics compositions more complex. In most cases this change means that uses of L.define or L.required with an empty value {}, [], or "", can simply be removed. L.define and L.required now give a warning in case they are used with an empty value and a matching empty value passes through them redundantly. In cases where removal of empty values is desired, one can e.g. compose with L.defaults. In cases where some default value is needed, one can e.g. compose with L.valueOr.

Removed previously obsoleted L.findHint.
