How to get number of plugins installed?

[Maritsu]

Like the title says, I'm looking for a way to get the number/amount of currently installed plugins. Does anyone know whether it's possible to do this? If so, how could I achieve this?
Thanks in advance

local function get_table_size(t)
	local count = 0
	for _, __ in pairs(t) do
		count = count + 1
	end
	return count
end

get_table_size(_G.packer_plugins)

is there a way to wait till packer_compiled.lua is loaded?

After require('packer').startup, I think it's loaded.

I was looking at the source code and thought that it might be better to use this function. This way it's not timing dependent.

https://github.com/wbthomason/packer.nvim/blob/1d0cf98a561f7fd654c970c49f917d74fafe1530/lua/packer/plugin_utils.lua#LL101C10-L101C10

what's util in this situation?

util is this one.

util = require 'packer.util'

It's also in the example setup.

In that case, what function should I use to get the plugin count so that it's not "timing dependent"?

(Also, getting the plugin count is done after require("packer").startup() in my case. Hell, it's done right at the end of the config)

local function get_table_size(t)
  local count = 0
  for _, __ in pairs(t) do
    count = count + 1
  end
  return count
end
local opt, start = require('packer.plugin_utils').list_installed_plugins()
local plugin_count = get_table_size(opt) + get_table_size(start)
print(plugin_count)

Using _G.packer_plugins in init.lua was not correct because it is loaded after the init.lua file is loaded.
require('packer.plugin_utils').list_installed_plugins() is a better way to do this.

It finally works, thank you very much!!
