vim-glance

UPDATE: The glance-vim now supports Asciidoc and POD file types. You can preview these file types within the vim editor by typing :Glance in a buffer that houses these specific file types.

The plugin offers a customization mechanism for rendering documents using markdown-it plugins. If you desire to use emojis within your markdown, you can simply append markdown-it-emoji plugin URL to the g:glance#plugins as shown below:

let g:glance#markdown_plugins = ['https://esm.sh/markdown-it-emoji']

The above plugin is loaded dynamically within Deno, consequently rendering the buffer content with markdown-it. The rendered content is subsequently dispatched as an HTML document to your browser.

Glance Vim offers various handy features:

• Monitoring cursor movement within Vim.
• Adding a custom preamble to the beginning of your HTML output.
• Facilitating content synchronization between the buffer and the browser.
• Operating in offline mode where Deno caches the markdown-it plugins.

Begin crafting your documents with your own flavored markdown.
