render-markdown.nvim is a Neovim plugin that transforms raw markdown syntax into a visually formatted layout directly inside the editor. It acts as a component visualizer and syntax highlighter, replacing standard markdown elements with custom symbols, icons, and formatted blocks to improve document readability.
The plugin provides a toggle between rendered visual layouts and raw text views, allowing users to switch based on their current needs. It also applies markdown styling to injected content sections found within non-markdown file types.
The system covers the visualization of various document elements, including tables rendered as grids, stylized callouts, checkboxes, and code blocks with configurable borders. It manages document hierarchy through heading styling, indentation guides, and vertical markers.
To maintain performance in large files, the renderer limits visual updates to the currently visible viewport.
