Toggling settings like showImplicitArguments

[TimWSpence]

Apologies if this is just my inexperience with neovim but is there a way to dynamically toggle metals config like showImplicitArguments and showInferredType? I did this quite frequently via the emacs plugin so I believe it is theoretically possible but have no idea how that functionality is exposed

Hey @TimWSpence, yup, we have a toggle_setting function in the Lua API that you can use for this. You can see some notes about it here:

nvim-metals/doc/metals.txt

Lines 1027 to 1040 in 1b90531

	*toggle_setting()*
	toggle_setting({setting})
	Use to toggle a boolean setting in |metals-settings|.
	If the setting is not set, you'll be toggling it on.
	Parameters:
	{setting} (string) the name of the setting that
	you'd like to toggle.
	Example usage: >
	lua require("metals").toggle_setting("showImplicitArguments")
	<

Aha! I thought it probably existed somewhere. You're a legend ❤️ Is that documented somewhere? I'm very happy to attempt to raise a PR if not - feels like very useful functionality for most people

Ah, well I mean what I linked is the documentation ha. Everything for nvim-metals should be contained in there. So exploring :h nvim-metals will give you all sorts of info.

You can tell I'm new to nvim... 😅 Although I should have guessed that from the file path. Anyway, thanks so much for your help!
