REQUIREMENTS *lazy.nvim-requirements*
- Neovim >= **0.8.0**
INSTALLATION *lazy.nvim-installation*
You can use the following Lua code to bootstrap **lazy.nvim**
2022-12-15 08:07:46 +00:00
>lua
2022-12-14 23:23:54 +00:00
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
vim.fn.system({
"git",
"clone",
"--filter=blob:none",
"--single-branch",
2022-12-16 14:11:06 +00:00
"git@github.com:folke/lazy.nvim.git",
2022-12-14 23:23:54 +00:00
lazypath,
})
end
2022-12-16 14:11:06 +00:00

2022-12-14 20:58:18 +00:00
Next step is to add **lazy.nvim** to the top of your `init.lua`

-- You can use a lua module that contains your plugins.
-- All sub modules of the lua module will also be automatically loaded
-- This is the preferred setup so your plugin specs can be properly cached.

-- add any optional configuration here
2022-12-14 20:55:03 +00:00

STARTUP SEQUENCE *lazy.nvim-startup-sequence*
**lazy.nvim** does **NOT** use Neovim packages and even disables plugin loading
completely (`vim.go.loadplugins = false`). It takes over the complete startup
sequence for more flexibility and better performance.
In practice this means that step 10 of |Neovim Initialization| is done by Lazy.
