feat: folder notes integration

[piotrnajda3000]

Addresses #98

Note

This is vibecoded to make it work. Is it efficient? Does it make architectural sense? Not sure. However, it can serve as a starting point for anyone interested, as it's at least an MVP/POC, since it works for my need of adding an icon to a Folder Note.

Tip

If you want to use this now, feel free to go to my fork at https://github.com/piotrnajda3000/iconic/tree/folder-notes-integration, build the project, and copy main.js, manifest and styles.css into .obsidian/plugins/iconic.

Example

Rulebook:

With setting on for a Folder Note:

With setting off:

Changes Made (AI Generated)

1. IconicPlugin.ts - Added a new setting integrateFolderNotes (boolean, default false) to the IconicSettings interface and DEFAULT_SETTINGS.

2. Strings.ts - Added UI strings for the new setting:
   • integrateFolderNotes.name: "Folder Notes integration"
   • integrateFolderNotes.desc: "Apply file rules to folders when the matched file is that folder's Folder Note."

3. IconicSettingTab.ts - Added a toggle control in the "Sidebars & tabs" section to enable/disable the Folder Notes integration.

4. FileIconManager.ts - Implemented the core integration logic:
   • Added a folderNoteCache Map to cache folder → folder-note path mappings
   • Added clearFolderNoteCache() method to reset the cache
   • Added getFolderNotePath() helper method that:
   • Checks for detached folder notes first using Folder Notes plugin's excludeFolders settings
   • Computes attached folder note paths based on Folder Notes' folderNoteName, storageLocation, and folderNoteType settings
   • Falls back to supportedFileTypes if primary type not found
   • Modified refreshIcons() to clear the cache on each refresh
   • Modified refreshChildIcons() to:
   • For folders: check for a folder-note file ruling if no folder rule exists and integration is enabled
   • Apply the color-only folder-note rules by showing a colored default folder icon
   • Proper precedence: Folder rule > Folder-note rule > Manual folder icon

Hi! I won't be using this particular solution in the plugin, since I don't use AI-generated code in my projects for maintenance reasons. I'll leave this PR open in the meantime though, since other people might find it useful. ✨
