🚀 Usage

Here's how to use the KOReader Highlights Importer:

1. Connect your KOReader device to your computer and ensure it's mounted. You should see it as a removable drive or volume.
2. Open your Obsidian vault.
3. Trigger the Import Process: You can import highlights in two ways:
   • Using the Command Palette: Press Ctrl/Cmd + P, type "Import KOReader Highlights", and select the command.
   • Using the button in the plugin settings: Click the "Import KOReader Highlights" button in the plugin settings.
4. (Optional) Scan for Highlights First: If you want to see which files will be processed before importing, you can use the "Scan KOReader Highlights" command. This will generate a list of found .sdr directories in a note named "KOReader SDR Files.md".

🎨 Templating System

Customize your notes by creating your own templates in the folder specified in the settings (default: KOReader/templates).

• Conditional Logic: Only show a section if a variable exists. For example, to only show the note section if a note exists: {{#note}}> [!NOTE] {{note}}\n{{/note}}.
• Automatic Note Formatting: The plugin automatically prefixes each line of a {{note}} with > for blockquote formatting if you don't do it yourself.
• Variables: Use the following variables in your templates.

Variable	Description
{{highlight}}	The highlighted text, with styling (<mark>, <u>, etc.) applied.
{{note}}	The text of the note associated with the highlight.
{{notes}}	An array of all notes in a merged highlight group.
{{pageno}}	The page number where the highlight appears.
{{chapter}}	The name of the chapter containing the highlight.
{{date}}	The date the highlight was made (formatted like "Jan 1, 2024").
{{isFirstInChapter}}	A boolean (true/false) you can use for conditional logic.

Troubleshooting

• Error Messages: If you encounter issues, open the Obsidian Developer Console (Ctrl/Cmd + Shift + I on Windows/Linux, Cmd + Option + I on macOS) and check for error messages related to the plugin.
• Mount Point: Double-check that you've entered the correct mount point for your KOReader device in the plugin settings.
• Permissions: Ensure that Obsidian has the necessary permissions to access the mounted KOReader device and your specified highlights folder.

Development

• Install Dependencies with pnpm: pnpm install
• Building: Use pnpm run build to compile the plugin.
• Testing: The plugin uses Obsidian's API for file operations and plugin lifecycle management.
