Markdown and LaTeX support

SecondLoop’s Markdown editor and preview support common note-writing syntax plus LaTeX rendering.

Markdown support​

  • Headings, lists, links, quotes, code blocks, inline code
  • Tables and common GitHub-style Markdown constructs
  • Image embedding in markdown preview/export
  • Sanitization to reduce accidental indented-code formatting issues

LaTeX support​

  • Inline formula: $...$
  • Block formula: $$...$$
  • Rendered with math components in app preview and KaTeX-backed export pipeline

If a formula fails to parse, rendering falls back to plain text output instead of hard failure.

Mindmap-style block support​

  • Fenced block with language markmap or mindmap is parsed as a structured map block in preview.

Example:

```markmap
# Project
## Milestone A
## Milestone B
```

Export behavior​

  • Markdown editor supports export actions (such as clipboard/image/PDF flows in supported platforms).
  • PDF export keeps markdown structure and renders LaTeX via bundled KaTeX assets.
