Does packer support nested lists of plugins?

[danielo515]

Hello, and as always, thanks again for packer.
Today I realized that, under my main list of plugins, I have some nested lists of plugins, and I am not sure if packer is able to pick them? Maybe it is some side effect from a flatten call, or maybe it is an intended design decission? The thing is that I don't get any error, and everything seems to work, but I didn't saw any reference to poviding nested list of plugins.
To put it in concrete terms, this is what I am talking about

use {
  "plugin/x", -- normal plain usage
  { "plugin/y" }, -- plugin defined as a table
  {
    { "plugin/a"}, -- nested  table of plugins defined as tables
    { "plugin/b"},
  }

}

Yes packer does support nested lists of plugins. A plugin spec can either be a string or a table. A string is just a simple plugin with no extra configuration. A table is a spec that has some sort of additional keys assigned (config, opt, ft...). A table spec MUST have the first value as the name as a string. For example this is invalid:

use {
  { config = function() end, "user/repo"  }, -- invalid
}

-- All valid
use {
  "user/repo", -- single
  {
    "user/repo", -- list of singles
    "user/repo",
  },
  { "user/repo" }, -- complex with additional keys
  {
    { "user/repo" }, -- list of complex with additional keys
    { "user/repo" },
    { "user/repo" },
  },
}

This is the same for the requires key's value. Make sure you have the correct number of tables.

That's good to know, thanks. My last question, specifically about the list of complex with additional keys... is the allowed nesting arbitrary? Or just one level of nesting is permitted? In case of more than the allowed nesting is provided, will it error out?

Thank you very much for your quick answer by the way.

There is no restriction on the level of nesting. When nesting you have to make sure that the each nesting level is a list.

Awesome! Thank you so much for the answers.
