How to set "open.edit" to "l" key

[RicardoRien]

In my old config I was able to open folders and file just with the key "l", instead or . It was to this:

nvim_tree.setup {
  mappings = {
    custom_only = false,
    list = {
      { key = { "l", "<CR>", "o" }, cb = tree_cb "edit" }
    },
  },
}

But It doesn't work with:

vim.keymap.set('n', 'l',  api.node.open.edit,                    opts('Open'))

I'm using that same open mapping:

Please post your full nvim_tree.setup and your on_attach.

Don't forget to link your on_attach e.g.

nvim_tree.setup {
  on_attach = your_on_attach,

@alex-courtis this is my config but still appearing a message everytime I init Neovim

local status_ok, nvim_tree = pcall(require, "nvim-tree")
if not status_ok then
  return
end

local config_status_ok, nvim_tree_config = pcall(require, "nvim-tree.config")
if not config_status_ok then
  return

I'm not seeing your on_attach function. It looks like it might be nil, hence your view.mappings are being read.

Please see https://github.com/nvim-tree/nvim-tree.lua/wiki/Migrating-To-on_attach

Thanks a lot, this works for me:

local function my_on_attach(bufnr)
  local api = require "nvim-tree.api"

  local function opts(desc)
    return { desc = "nvim-tree: " .. desc, buffer = bufnr, noremap = true, silent = true, nowait = true }
  end

  -- default mappings
  api.config.mappings.default_on_attach(bufnr)

  -- custom mappings
  vim.keymap.set('n', '<C-t>', api.tree.change_root_to_parent,        opts('Up'))
  vim.keymap.set('n', '?',     api.tree.toggle_help,                  opts('Help'))
  vim.keymap.set('n', 'l',     api.node.open.edit,                    opts('Open'))
end
