NoteMD Pro - Selection-Based Processing

Overview

This skill enables processing of selected text portions within files, rather than forcing full-file rewrites. This saves tokens, reduces processing time, and allows targeted AI operations on specific sections.

When to Use

• Partial content generation: Generate content for just a section
• Selective linking: Add links to specific paragraphs
• Targeted translation: Translate selected portions
• Efficient processing: Save tokens by processing only what's needed

Function Call Chain

Process Selection
├── Get selected text from editor
├── Get surrounding context (optional)
├── Process selected content (LLM)
├── Replace or append selected content
└── Update file

Selection Processing Patterns

1. Get Selected Text

// From Obsidian editor
const editor = view.editor;
const selection = editor.getSelection();

// From VS Code
const selection = editor.selection;
const text = editor.document.getText(selection);

2. Process with Context

For better results, include surrounding context:

// Get context before and after selection
const lineNum = editor.getCursor().line;
const beforeLines = editor.getRange({line: 0, ch: 0}, {line: lineNum, ch: 0});
const afterLines = editor.getRange({line: lineNum, ch: 0}, {line: maxLine, ch: 0});
const fullContext = beforeLines + selection + afterLines;

3. Replace Selection

// Replace selected text with processed result
editor.replaceSelection(processedContent);

// Or append after selection
editor.replaceRange('\n\n' + processedContent, {line: lineNum + 1, ch: 0});

Use Cases

Wiki-Link from Selection

// Selected: "Machine learning is a subset of AI"
// Process: Add links to key concepts
// Result: "Machine learning is a subset of [[AI]]"
async function addLinksToSelection(app: App, editor: Editor) {
    const selection = editor.getSelection();
    const prompt = getSystemPrompt('addLinks');
    const result = await callLLM(prompt, selection);
    editor.replaceSelection(result);
}
