Steps To Reproduce

init.lua

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",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable",
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)
require("lazy").setup({
  spec = {
    {
      "folke/which-key.nvim",
      url = "https://gitee.com/sunn4github/which-key.nvim.git",
      opts = {},
    },
    {
      "folke/which-key.nvim",
      opts = {},
    },
  },
  install = {
    missing = true,
  },
})

lazy.nvim clone the folke/which-key.nvim from https://github.com/folke/which-key.nvim.git

tbh I would expect that as a user

I know the order of spec is important to lazy.nvim, but I think some option shouldn't be overwritten, etc url. Because the same plugin spec may locate in different files.

If Not necessary, I would close this issue.

[max397574]

I'd exactly expect url to be one of the ones that get overwritten

[sunn4room]

There is no problem that overwrite the url, but a real value shouldn't be overwritten by nil.

Anyway, good work about lazy.nvim, this is a great package manager.

real value shouldn't be overwritten by nil

As said before: I'd expect that to be the behavior

lazy.nvim/lua/lazy/core/plugin.lua

Line 536 in 9658486

Config.spec:parse({ vim.deepcopy(Config.options.spec), { "folke/lazy.nvim" } })

this line force the 'folke/lazy.nvim' clone from 'https://github.com/folke/lazy.nvim'. But in China, it is difficult to access github.

I expect:

  Config.spec:parse({ { "folke/lazy.nvim" }, vim.deepcopy(Config.options.spec) })

THEN I can use my own mirror url to clone 'lazy.nvim'.
