What is the issue affecting?

Annotations

Expected Behaviour

The ability to define multiple return values for a field annotation.

Actual Behaviour

Any non-identifier symbol following a type is treated as a comment or a break.

Reproduction steps

1. Create a field with a comma separated return type.
2. See that anything following the comma is treated as a comment.

Additional Notes

---@class Color
---@field [string] Color,string
Color = {}

,string is highlighted as a comment.

---@class Color
---@field [string] Color, string
Color = {}

, is highlighted as a symbol, string is highlighted as a comment.

An example of fields with multiple return types are the named color lookups in the Tabletop Simulator API:
https://api.tabletopsimulator.com/color/#colorblue

local color, name = Color.Blue
print(color) -- Color: Blue { r = 0.118, g = 0.53, b = 1, a = 1 }
print(name) -- Blue

local color, name = Color.Red
print(color) -- Color: Red { r = 0.856, g = 0.1, b = 0.094, a = 1 }
print(name) -- Red

まず、提供された Lua スニペットを使ってアノテーションパーサーの動作を再現し、@field 宣言の後にあるカンマ区切りの型がどのようにトークン化されるかに注目します。Color,string のような複数の戻り値型がアノテーション型として認識され、残りの部分がコメントとして扱われないことを確認できれば完了です。リポジトリに関連するパーサーテストがある場合は、カバレッジを追加または更新してください。
