{
    "The-Plottwist/nvim-session-manager",
    branch = "stable"
}

Defaults:

defaults = {
    events = {"VimPreLeave"},

    --For more info: help sessionoptions
    save_options = { "blank", "buffers", "curdir", "help", "skiprtp", "tabpages", "winsize", "winpos" },

    session_dir = vim.fn.stdpath("state") .. path_seperator .. "sessions",
	
    default_session = "last_session"
}

Notes

-To modify: require("session-manager").setup({events = {}, ...})

-Does not load any sessions by default

-Adds an ungrouped UIEnter event seperate from User events to refresh buffers when a session is loaded before UI (Gives error on empty tabpages, please close empty tabs).

Example Usage:

--enable the plugin
require("session-manager").setup()

--check if a file argument is given at vim start
vim.cmd("let g:ARGC = argc()")

--load last_session if no file argument is given
if vim.g.ARGC == 0 then
    require("session-manager").load()
end

-No need to assign to a variable like manager = require(...) as lua stores all require calls as table values where described in the section 8.1 of Programming in Lua: "[...]it keeps a table with the names of all loaded files. If a required file is already in the table, require simply returns." (Not recommended outside of configuration files)
