Redmine Markdown Preview & Converter

About

> Detailed Description:

This extension brings a modern Markdown editing experience to legacy Redmine environments that still rely on Textile formatting — no server changes required.


> What it does:

Side-by-side preview — a persistent split panel next to Redmine editors (issues, wiki, news, messages) renders Markdown or Textile in real time with GitHub-style formatting.

Syntax selector — switch between Markdown and Textile mode with a single click.

One-click conversion — convert Markdown → Textile or Textile → Markdown. A Restore button lets you undo the conversion instantly.

Auto-detection — empty editors default to Markdown. Existing content is analyzed with a Textile-first / Markdown-assisted heuristic. Large pastes trigger re-detection automatically.

Scroll synchronization — editor and preview scroll positions stay roughly synchronized.

Syntax highlighting — code blocks are highlighted automatically.

100% local — all preview and conversion logic runs inside your browser. No data is ever sent to an external service.
Supported Redmine pages:

Issues (notes and descriptions), Wiki, News, Messages/Forums.
