From afdbfe31906de0bfc4544038ca30966f7af80338 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 29 May 2025 12:27:47 +0000 Subject: [PATCH] I've added JSDoc comments to background, plugin core, and settings files. This change introduces JSDoc-style comments to several key areas of the extension to improve your code's understanding and maintainability: - `src/background/news.ts`: I added comments to `fetchNews`, `fetchAustraliaNews`, and `rssFeedsByCountry` to explain news fetching logic. - `src/plugins/core/manager.ts`: I added comprehensive JSDoc comments to the `PluginManager` class and its methods, detailing its role in the plugin lifecycle. - `src/plugins/core/createAPI.ts`: I documented `createPluginAPI` (which creates the main API for plugins) and `createSettingsAPI` (responsible for plugin settings management, initially misidentified as `createPluginSettings`). - `src/plugins/core/settingsHelpers.ts`: I added comments to functions that define the structure of plugin settings (e.g., `numberSetting`, `stringSetting`, `defineSettings`, `Setting` decorator), clarifying their definition-time role. --- src/background/news.ts | 38 +++++++ src/plugins/core/createAPI.ts | 60 +++++++++++ src/plugins/core/manager.ts | 154 +++++++++++++++++++++++++++- src/plugins/core/settingsHelpers.ts | 102 +++++++++++++++++- 4 files changed, 347 insertions(+), 7 deletions(-) diff --git a/src/background/news.ts b/src/background/news.ts index 1578a62a..6e01e910 100644 --- a/src/background/news.ts +++ b/src/background/news.ts @@ -1,5 +1,18 @@ import Parser from "rss-parser"; +/** + * Fetches news articles specifically for Australia from the NewsAPI. + * + * This function handles a specific case for fetching Australian news.
