You are puzzled by neovim sessions and are not using them, are you? Start your pos-sessions journey, fear no more!

This plugin is a no-nonsense session manager built on top of fzf-lua (required) that makes managing sessions quick and visually appealing: dynamically browse through your existing sessions, create new ones, update and delete with a statusline component to remind you of where you are. See for yourself:

Install nvim-possession with your favourite plugin manager (fzf-lua is required) and invoke require("nvim-possession").setup({}); in order to avoid conflicts with your own keymaps we do not set any mappings but only expose the interfaces, which means you would need to define them yourself. The suggested quickstart configuration is, for instance

• with lazy.nvim

{
    "gennaro-tedesco/nvim-possession",
    dependencies = {
        "ibhagwan/fzf-lua",
        -- OR
        "nvim-telescope/telescope.nvim",
    },
    config = true,
    init = function()
        local possession = require("nvim-possession")
        vim.keymap.set("n", "<leader>sl", function()
            possession.list()
        end)
        vim.keymap.set("n", "<leader>sn", function()
            possession.new()
        end)
        vim.keymap.set("n", "<leader>su", function()
            possession.update()
        end)
    end,
}

Exposed interfaces

The possession.list() function lists the session via fzf or telescope.nvim. See below on how to set that up.

As shown above the main use of the plugin is to show all existing sessions (say via <leader>sl) and load the selected one upon <CR>. Once a session is loaded a global variable is defined containing the session name (to display in a statusline - see below - or to validate which session is currently active). New sessions can also be created and updated on the fly, and they will show when you next invoke the list.

Default configurations can be found in the config and can be overriden at will by passing them to the setup({}) function: in particular the default location folder for sessions is vim.fn.stdpath("data") .. "/sessions/",. You should not need to change any of the default settings, however if you really want to do so:

require("nvim-possession").setup({
  sessions = {
    sessions_path = "...", -- folder to look for sessions, must be a valid existing path
    sessions_variable = "...", -- defines vim.g[sessions_variable] when a session is loaded
    sessions_icon = "...",
  },

  viewer = "fzf|telescope", -- which plugin you want to use to display the sessions
  dressing = true, -- enable a ui when asking for a new session name
  autoload = false, -- detect and autoload sessions in cwd

  telescope = {
    theme = "get_dropdown", -- the telescope theme you want to use
  },

  fzf_winopts = {
    -- any valid fzf-lua winopts options, for instance
    width = 0.25,
    preview = {
      horizontal = "down:40%",
    },
  },
})

If you want to automagically load sessions defined for the current working directory at startup, specify

require("nvim-possession").setup({
  autoload = true
})

This autoloads sessions when starting neovim without file arguments (i. e. $ nvim ) and in case such sessions explicitly contain a reference to the current working directory (you must have vim.go.ssop+=curdir); this is by design as this plugin intends to be as less invasive as possible.

You can call require("nvim-possession").status() as component in your statusline, for example with lualine you would have

lualine.setup({
  sections = {
    lualine_a = "...",
    lualine_b = "...",
    lualine_c = { { "filename", path = 1 }, { "require'nvim-possession'.status()" } },
  },
})

to display

the component automatically disappears or changes if you delete the current session or switch to another one.
