disable autoload of not 'used' plugins

[fedoranvar]

Good day to you!

I have constraint in neovim config,that gives me abillity to choose between minimal and full configs.

I have all plugins installed (cloned) in packer directory.

When i try to load minimal config, even if i do not use some plugins - they still autoloaded (VimL).

Question: is it possible to not autoload not use'd plugins? (Maybe some argument in use {}?

Thank you!

Hi! This is due to how native packages work in Neovim - start packages are sourced by default, and unfortunately cannot (easily) be skipped. However, packer already has a feature that sounds perfect for your use case - use the cond keyword to specify that each of your extra plugins should only load if vim.g.is_extra is true. That would look something like:

use {
  'somebody/someplugin',
  cond = 'vim.g.is_extra'
}

Yes, that did what i need, but i've encountered another thing:

i've templated each module like:

/module_name/[init.lua, config.lua, keymaps.lua]

and in init.lua i require config.lua and keymaps.lua and in requiring i'm using ...

require("packer").use({
    "tpope/vim-dadbod",
    "kristijanhusak/vim-dadbod-ui",
    config = function()
        require(... .. ".config")
        require(... .. ".keymaps")
    end,
    cond = "vim.g.is_extra",
})

How i can pass variable from outer scope to config function?

Thank you!

Sorry, but I'm not sure I understand what you're after here - you want to replace the ... with some module name, but automatically?

[fedoranvar]

in short, yes

---

using ... allows me to template plugins configuration.

So if i'm adding new plugin to my neovim config i've to cp -r template folder and edit init.lua config.lua keymaps.lua

for example, we have structure:

vim-daddbod/init.lua
vim-dadbod/config.lua
vim-dadbod/keymaps.lua

if i'll require('vim-dadbod') then print(...) in init.lua will print 'vim-dadbod'

so ... returns path by which file was required.

---

returning to previous post,

require(... .. ".config")
require(... .. ".keymaps")

works great by itself, so at the end its

require("vim-dadbod.config")
require("vim-dadbod.keymaps")

, but when i put it into config function of use, it returns:

is it possible to get that functionality in config function of use?

Thank you!

UPD.

I've come up with solution:

require("packer").use({
    cond="vim.env.NEOVIM_EXTRA",
    config = ""
        .. "require(\"" .. ... .. ".config\")"
        .. "require(\"" .. ... .. ".keymaps\")"
})

but i have question: by reading docs i assumed that cond and config are dedicated to one plugin, so i can't relate one config and cond to multiple plugins at once? e.g.

require("packer").use({
    "nvim-telescope/telescope.nvim",
    "nvim-telescope/telescope-symbols.nvim",
    "nvim-telescope/telescope-fzf-writer.nvim",
    "nvim-telescope/telescope-hop.nvim",
    {
        "nvim-telescope/telescope-fzf-native.nvim",
        run = "make",
    },
    requires = {
        "nvim-lua/popup.nvim",
        "nvim-lua/plenary.nvim",
    },
    cond="vim.env.NEOVIM_EXTRA",
    config = ""
        .. "require(" .. ... .. "\".config\")"
        .. "require(" .. ... .. "\".keymaps\")"
})

So my only option is to apply config and cond to each plugin-entry?

Sorry, I'm still quite confused about how this works in terms of basic Lua. You're saying that evaluating ... (which I only know as the vararg expression) in a non-function context gets you the directory path name, somehow? Would you mind linking me to docs for this?

As for reusing cond and config values, I should be merging #647 soon which will allow this.

not docs, but i used this link: https://stackoverflow.com/questions/9145432/load-lua-files-by-relative-path
