Rich.nvim

A rich-cli preview directly in your neovim buffer.

Prerequisites

Neovim 0.5 or higher

Installing

Plug 'ginsburgnm/rich.nvim'

with packer.nvim

use {"ginsburgnm/rich.nvim"}

Configuration

rich_path

Use g:rich_path for vimscript config or vim.g.rich_path for lua config.

If set, this path will be used to execute rich. Otherwise rely on $PATH.

If rich is not on $PATH or rich__path is set and rich is not found the popup will return this error

Example:

let g:rich_path = "~/venv/bin/rich"

vim.g.rich_path = "~/venv/bin/rich"

rich_border

Use g:rich_border for vimscript config or vim.g.rich_border for lua config.

If set, this will change the border of the window. Type :help nvim_open_win for border options.

Example:

let g:rich_border = "rounded"

vim.g.rich_border = "rounded"

rich_width

Use g:rich_width for vimscript config or vim.g.rich_width for lua config.

If set, this will change the width of the window.

Example:

let g:rich_width = 120

vim.g.rich_width = 120

rich_style

Use g:rich_style for vimscript config or vim.g.rich_style for lua config.

If set this will change the theme used by rich (all pygments names should work) default is material

Example:

let g:rich_style = "dracula"

vim.g.rich_style = "dracula"

Usage

:Rich [path-to-md-file]

Pressing q will automatically close the window
No path arg means rich uses current path in vim
:Rich command will work as toggle feature, so calling it will open or close the current preview
you can also pass arbitrary arguments to rich-cli when doing so all arguments must come after the file name or you must not provide a filename

Example to force markdown rendering on current file

:Rich -m

You can also create a mapping getting a preview of the current file

noremap <leader>p :Rich<CR>

For users who want to make rich.nvim buffer fullscreen, there's a native vim keybinding

Ctrl-w + | set window's width max
Ctrl-w + _ set window's height max

Or you can have a fullscreen option by creating a mapping for setting both window's height and width max at once

noremap <C-w>z <C-w>\|<C-w>\_

Screenshots

Pictures are worth a thousand words

Here we see the preview window displaying markdown with the plugin's default border settings

Here we are previewing with border set to "rounded" (I have changed the color of my border by setting highlight for FloatBorder

Similarly we can preview RST in the same manner

As well as CSV files.

And JSON files you will note here that I specified to preview a different file than the one I an currently editing by providing a file path.

I wll not interate through all the possibilities that rich-cli allows us to preview. If rich-cli can preview a file this plugin should be able to show it in a pop-up window.

Credits

This was HEAVILY influenced by glow.nvim to the point where most of the code (and even this readme) is copy paste, then find-rename.

Some of the configs I haven't actually tested but it looked like they were parameters to the neovim buffer windows so it should just work.
