nvim-origami 🐦

Features

• Use h at the first non-blank character of a line (or before) to fold. Use l anywhere on a folded line to unfold it.¹ This allows you to ditch zc, zo, and za – you can just use h and l to work with folds. (h still moves left if not at the beginning of a line, and l still moves right when on an unfolded line – this plugin basically "overloads" those keys.)
• Pause folds while searching, restore folds when done with searching. (Normally, folds are opened when you search for some text inside a fold, and stay open afterward.)
• Remember folds across sessions (and as a side effect, also the cursor position).

[!NOTE] This plugin only opens and closes folds. It does not provide a foldmethod. You need to define a foldmethod either yourself or through a folding provider like nvim-ufo for this plugin to work.

Installation

-- lazy.nvim
{
	"chrisgrieser/nvim-origami",
	event = "BufReadPost", -- later or on keypress would prevent saving folds
	opts = {}, -- needed even when using default config
},

-- packer
use {
	"chrisgrieser/nvim-origami",
	config = function () 
		require("origami").setup ({}) -- setup call needed
	end,
}

The .setup() call or lazy's opts is required. Otherwise, the plugin works out of the box without any need for further configuration.

Configuration

-- default settings
require("origami").setup {
	keepFoldsAcrossSessions = true,
	pauseFoldsOnSearch = true,
	setupFoldKeymaps = true,
	hOnlyOpensOnFirstColumn = false,
}

[!TIP] By setting 'startofline' to true, bigger movements move you to the start of the line, which works well with this plugin's h key.

If you use other keys than h and l for vertical movement, set setupFoldKeymaps = false and map the keys yourself:

vim.keymap.set("n", "<Left>", function require("origami").h() end)
vim.keymap.set("n", "<Right>", function require("origami").l() end)

Limitations

Many formatting plugins open all your folds and unfortunately, there is nothing this plugin can do about it. The only two tools that are able to preserve folds are the efm-language-server and conform.nvim.

Other useful folding plugins

• fold-cycle.nvim
• nvim-ufo
