Plugin to improve viewing Markdown files in Neovim
Screenshot | Video |
---|---|
- Contained: runs entirely inside Neovim with no external windows
- Configurable: all components, padding, icons, and colors can be modified
- File type agnostic: can render
markdown
injected into any file- Automatically runs on lazy load file types defined in
lazy.nvim
ft
- Automatically runs on lazy load file types defined in
- Injections: can directly manipulate treesitter to add logical
markdown
sections - Modal rendering: changes between
rendered
andraw
view based on mode - Anti-conceal: hides virtual text added by this plugin on cursor line
- Window options: changes option values between
rendered
andraw
view - Large files: only renders visible range, can be entirely disabled based on size
- Custom rendering: provides extension point where user can add anything
- Renders the following
markdown
components out of the box:- Headings: icon, color, border, padding 1, width
- Code blocks: background, language icon 1 2, border, padding 1, width
- Code inline: background
- Horizontal breaks: icon, color, width
- List bullets: icon, color, padding 1
- Checkboxes: icon, color, user defined states 1
- Block quotes: icon, color, line breaks 1
- Callouts: icon, color, user defined values, Github & Obsidian defaults
- Tables: border, color, alignment indicator, auto align cells 1
- Links 1: icon, color, user defined destinations
LaTeX
blocks 3: renders formulas- Org indent mode 1: per level padding

We use the following definitions when discussing indexing into lists:
- Cycle: Indexed
mod
the length. Example:{ 1, 2, 3 }
@ 4 = 1. - Clamp: Indexed normally but larger values use the last value in the list.
Example:
{ 1, 2, 3 }
@ 4 = 3.

Note
vimwiki overrides the filetype
of
markdown
files, as such there are additional setup steps.
- Add
vimwiki
to thefile_types
configuration of this plugin
require('render-markdown').setup({
file_types = { 'markdown', 'vimwiki' },
})
- Register
markdown
as the parser forvimwiki
files
vim.treesitter.language.register('markdown', 'vimwiki')
Note
obsidian.nvim provides UI functionality
that is enabled by default. While there may be a way to have the 2 work together,
for the foreseeable future only one of these plugins should be used for the UI.
If you choose this plugin disable the obsidian.nvim
UI with:
require('obsidian').setup({
ui = { enable = false },
})
You can also do something more custom like lazy loading this plugin via a command
and adding logic to the config method to disable obsidian.nvim
as suggested in
#116,
though things like this can break at any time given the reliance on internal logic:
return {
'MeanderingProgrammer/render-markdown.nvim',
cmd = { 'RenderMarkdown' },
dependencies = { 'nvim-treesitter/nvim-treesitter', 'echasnovski/mini.nvim' },
config = function()
require('obsidian').get_client().opts.ui.enable = false
vim.api.nvim_buf_clear_namespace(0, vim.api.nvim_get_namespaces()['ObsidianUI'], 0, -1)
require('render-markdown').setup({})
end,
}
Note
Images are only supported so far as this plugin will not interfere with others
like image.nvim, however nothing is done
natively by this plugin.
It is recommended to enable the only_render_image_at_cursor
option.

related plugins and how they co-exist
I enjoy working on these projects and will continue to do so with the time I can find. Any support is appreciated including starring the repo and reporting issues. Money is also nice: Donate via Stripe.
