Description

Feature Spec

This is a proposal to change all built-in types to use lowercase instead of PascalCase, so they all have a similar look and feel, and are also distinguishable from user-defined types.

So basically the lowercase versions are just aliases:

  • str
  • num
  • bool
  • duration
  • date
  • json
  • array<T>
  • set<T>
  • map<T>
  • mutarray<T>
  • mutset<T>
  • mutmap<T>

Use Cases

To reduce cognitive load, all types should have a similar look & feel.

As an example, see the spec for Json, which proposes the all built-in types will have a from_json() method.

Contributor guide

Research direction
Research the current type definitions in the Wing compiler (written in TypeScript) to find all places where built in types like 'Str', 'Num', 'Bool', etc. are defined. Then implement lowercase aliases (e.g., 'str', 'num', 'bool') and ensure they work correctly with parsing, type checking, and code generation.
