Description

Goals

• Users should be able to create new functions that take persisted enum types as their input or output types

Technical details

• Depends on T391918: [Front-end/Default view]: Allow easy creation and edition of valid and wellformed lightweight enum types
• Depends on T391915: [PHP/DB]: Audit and fix the way lightweight enum types are registered in the secondary tables to make them searchable
• Function Editor uses the component TypeSelector.vue for input and output type selection
• TypeSelector currently allows direct selection of:
  • objects of type Z4
  • generic types (functions that return a type Z4, such as typed list/Z881, typed pair/Z882 or typed map/Z883
    • the generic type lightweight enum type/Z884 should not be selectable
• TypeSelector currently doesn't allow selection of:
  • persisted generic types (e.g. a lightweight enum/Z6884 already persisted)
    • persisted lightweight enum types should be searchable and selectable

Example User Flow

Step 1: Create a Function that takes "Enumeration of grammatical gender"

Prerequisite: The persisted lightweight enum type "Enumeration of grammatical gender" should be created as described in T391918: [Front-end/Default view]: Allow easy creation and edition of valid and wellformed lightweight enum types

1. Go to the Function Editor to create a new function: https://www.wikifunctions.org/wiki/Special:CreateObject?zid=Z8
2. Set a name for your function
3. For the "Input 1", in the "Type" field, search for "enum"

Expected outcome:

• "Typed enum of Wikidata references" should not appear in the lookup options
• "Enumeration of grammatical gender" should appear in the lookup options
• Choosing "Enumeration of grammatical gender/Z23772" will create a function with an input type set to Z23772

---

Step 2: Publish the Function

1. Set a valid output (e.g. String)
2. Click "Publish"

Expected outcome:

• The function should be successfully persisted
• The user should be redirected to the function page
• The input type should be "Enumeration of grammatical gender"
