the experimental Lua module loader to speed up the start up process
If `true`, this will enable the experimental Lua module loader which:
- overrides loadfile
- adds the lua loader using the byte-compilation cache
- adds the libs loader
- removes the default Neovim loader
This is disabled by default. Before setting this option, please
take a look at the [{option}`official documentation`](https://neovim.io/doc/user/lua.html#vim.loader.enable()).

description = ''
Disables the default runtime paths that are set by Neovim
when it starts up. This is useful when you want to have
full control over the runtime paths that are set by Neovim.
::: {.note}
To avoid leaking imperative user configuration into your
configuration, this is enabled by default. If you wish
to load configuration from user configuration directories
(e.g. {file}`$HOME/.config/nvim`, {file}`$HOME/.config/nvim/after`
and {file}`$HOME/.local/share/nvim/site`) you may set this
option to true.

Additional runtime paths that will be appended to the
active runtimepath of the Neovim. This can be used to
add additional lookup paths for configs, plugins, spell
languages and other things you would generally place in
your {file}`$HOME/.config/nvim`.
This is meant as a declarative alternative to throwing
files into {file}`~/.config/nvim` and having the Neovim
wrapper pick them up. For more details on
`vim.o.runtimepath`, and what paths to use; please see
[the official documentation](https://neovim.io/doc/user/options.html#'runtimepath')

description = ''
Additional lua files that will be sourced by Neovim.
Takes both absolute and relative paths, all of which
will be called via the `luafile` command in Neovim.
See [lua-commands](https://neovim.io/doc/user/lua.html#lua-commands)
on the Neovim documentation for more details.
::: {.warning}
All paths passed to this option must be valid. If Neovim cannot
resolve the path you are attempting to sourcee, then your configuration
will error, and Neovim will not start. Please ensure that all paths
are correct before using this option.

An attribute set containing global variable values
for storing vim variables as early as possible. If
populated, this soption will set vim variables in the
built configRC as the first item.
E.g. {foo = "bar"} will set `g:foo` to "bar" where
the type of `bar` in the resulting vimscript will be
infered from the type of the value in the `{name = value}`
pair.

Verbatim lua code that will be inserted **before**

You do not want to override this option with mkForce
It is used internally to set certain options as early
