Autocompletion functions

[Datron]

Preamble

Today, all functions in superposition are only validation functions that have the signature:

function validate(name, value) -> bool

which helps a user validate their dimensions and default configs with external systems to further ensure safety of configs.

Problem

Users similarly have been asking for a feature that helps them fill the field in a form for dimensions/default configs with suggestions from an external system. We can start the implementation with dimensions.

Solution

Introduce a concept called function type that has 2 values:

• VALIDATION
• AUTOCOMPLETE

All existing functions will be marked as validation functions, and when a user creates a new function - they have the option to pick between these two options.

The signature of the AUTOCOMPLETE function is:

function autocomplete(name) -> [string]

The code is executed in a similar way for both function types with only the invocation changes.

DB changes

Create an enum to represent function types

CREATE TYPE function_types AS ENUM (
'VALIDATION',
'AUTOCOMPLETE'
);

then alter the functions table to add the column function type

ALTER TABLE functions ADD COLUMN function_type FUNCTION_TYPES NOT NULL;

UPDATE functions SET function_type = 'VALIDATION';

@Datron User might need multiple values to fetch the applicable values
