what is mdview fr?

MDview is a lightweight desktop app for reading and editing Markdown files, plain text, and simple HTML layouts, built with Go and Vue 3 through the Wails desktop framework. It works as a Windows desktop program you can open by double clicking a Markdown file or dragging one into the window. The app offers three ways of working with a document: a read only preview mode, a visual editing mode where changes save straight back to the source file, and a split view that shows the raw source and the rendered preview side by side with synced scrolling and a draggable divider. While editing, a right click menu lets you quickly insert headings, quotes, task lists, tables, images, code blocks, and Mermaid diagrams, and you can right click a heading to promote or demote it between levels one through six. MDview can open a single file, several files, or an entire folder, with a file tree and a document outline in the sidebar for jumping between sections. Beyond Markdown it also handles plain text, logs, config files, and code files, with support for several Chinese text encodings. If a file changes outside the app, it syncs the update automatically, and it will walk you through resolving a conflict if you have unsaved local edits at the same time. Rendering support includes syntax highlighted code blocks, Mermaid diagrams, images referenced by relative path, and enhanced display for task lists and tables. The app also includes optional AI assisted formatting, letting you connect multiple AI providers and models to reformat Markdown or HTML content, plus a visual HTML designer for adjusting page layout and exporting the result. Themes, fonts, and detailed style settings are configurable, and the interface remembers your chosen theme, mode, and sidebar width between sessions. Building from source requires Go 1.18 or newer, Node.js 16 or newer, and the Wails CLI. The project is licensed under the Apache License 2.0.
