how to call neo-tree actions from lua?

[Kamilcuk]

Hi, I would want to add some custom action to execute while neo-tree buffer is active. Not a mapping, rather for example to create a file when a menu item in the right mouse click menu is selected.

The mappins = { has many actions. How do I call these actions to do from a lua function to do in the context currently selected under the cursor inside neo-tree window?

For example in nvimtree I can do local api = require "nvim-tree.api" local node = api.tree.get_node_under_cursor api.fs.create(node()). How to do that in neo-tree?

There is execute https://github.com/nvim-neo-tree/neo-tree.nvim/blob/main/lua/neo-tree/command/init.lua#L46 but it only hides or shows, and it's for when neo-tree is not in focus. Neo-tree will be in focus.

There are commands https://github.com/nvim-neo-tree/neo-tree.nvim/blob/main/lua/neo-tree/sources/common/commands.lua#L107 , but how do I get the current state?

Thank you.

I think this works:

local manager = require "neo-tree.sources.manager"
local function call(cb)
  local state = manager.get_state_for_window()
  assert(state)
  return require("neo-tree.sources." .. state.name .. ".commands")[cb](state)
end

call("add_directory")

I believe you could simplify this to:

local manager = require "neo-tree.sources.manager"
local state = manager.get_state_for_window()
assert(state)
state.commands.add_directory(state)

i plan to add types for the neotree state soon to make the stuff available in state easier to discover, i've just had a busy week so haven't gotten around to it yet.

I tried both examples, but neither gave me expected behaviour,
for instance I have:

      {
        "<leader>r",
        function()
          require("neo-tree.command").execute({ toggle = true, dir = vim.uv.cwd(), reveal = true })
          local state = require("neo-tree.sources.manager").get_state_for_window()
          require("neo-tree.sources." .. state.name .. ".commands")["preview"](state)
          -- vim.defer_fn(function()
          --   local state = require("neo-tree.sources.manager").get_state_for_window()
          --   assert(state)
          --   state.commands.preview(state)
          -- end, 1000)
        end,
        desc = "Explorer NeoTree (Root Dir)",
        remap = true,
      },

but it fails.

1.         local state = require("neo-tree.sources.manager").get_state_for_window()
        require("neo-tree.sources." .. state.name .. ".commands")["toggle_preview"](state)
   

and
local state = require("neo-tree.sources.manager").get_state_for_window()
assert(state)
state.commands.preview(state)
have different behaviour, first works from second attemt, but display the preview in the main window,
second freezes preview on the first element.

2. on the first call preview command gives an error like it doesn't have a config

Im looking for a way to make a preview on constantly, did anyone solve it?

calling the same code form actions works well, e.g.:

          ["<esc>"] = {
            function(state)
              require("neo-tree.sources." .. state.name .. ".commands")["revert_preview"](state)
              require("neo-tree.sources." .. state.name .. ".commands")["cancel"](state)
            end,
            desc = "close preview and floating tree window",
          },
