toggle autostnippets

[SylvanFranklin]

I'm sure this is possible in the with some kind of scripting via the setup function, but it would be nice to have a dedicated method (unless I'm missing it from the docs). I have a bunch of snippets that are single letters that auto trigger, I would like to be able to enable and disable this functionality with a command. I came up with this to disable them:

local ls = require("luasnip")
vim.keymap.set({ "i", "s" }, "<C-c>", function()
    ls.setup({ enable_autosnippets = false })
end, { silent = false })

Which is most of what I want, but toggling them with the same shortcut would be nice. Maybe there is some way to do that in nvim like a state variable, or maybe some kind of query for the status of enable_autostnippets

This seems like a nice addition, and, while I have not yet considered changing settings of a running session (how it interacts with already-expanded snippets, for example), en/disabling autosnippets should not cause any issues as that only means re/unregistering an autocommand :)

I'll look into what other settings can be sensibly changed during a running session, until then (and it may be a while because I don't have much time to spend on luasnip at the moment) you can also assing require("luasnip").expand_auto to an empty function (function() end). (This is a bit better than the setup-variant because it loses other settings you may have in other calls to setup)

Thanks for the advice and your work on this! Good call to use an empty function, I just have a question: how would you go about creating a single command to toggle with this approach? It seems like it would require some kind of state (which maybe is more of a neovim question), or some kind of luasnip status query function.

Oh, for your config, I'd recommend something like

local enable_autosnippets = true
ls.setup({
	enable_autosnippets = enable_autosnippets
})

local expand_autosnippets_orig = ls.expand_auto
local nop = function() end
vim.keymap.set({ "i", "s" }, "<C-c>", function()
	enable_autosnippets = not enable_autosnippets
	if enable_autosnippets then
		ls.expand_auto = expand_autosnippets_orig
	else
		ls.expand_auto = nop
	end
end, { silent = false })

So, store the original function in a variable and then assign it or a function that does nothing based on enable_autosnippets, which tracks whether they are enabled.
