Auto-save for specific file

[xypnox]

I recently upgraded to the new version and setup the config as:

Is there a way to have utils.in(fn.getbufvar(buf, "&filetype"), {'md', 'tex', 'org', 'txt'}) as in:

local autosave = require("auto-save")

autosave.setup({
    enabled = true,
    execution_message = "AutoSave: saved at " .. vim.fn.strftime("%H:%M:%S"),
    events = {"InsertLeave", "TextChanged"},
    -- function that determines whether to save the current buffer or not
	-- return true: if buffer is ok to be saved
	-- return false: if it's not ok to be saved
	condition = function(buf)
		local fn = vim.fn
		local utils = require("auto-save.utils.data")
		if
			fn.getbufvar(buf, "&modifiable") == 1 and
            utils.in(fn.getbufvar(buf, "&filetype"), {'md', 'tex', 'org', 'txt'}) then
			return true -- met condition(s), can save
		end
		return false -- can't save
	end,
    write_all_buffers = false,
    debounce_delay = 135
})

Where I only want to save for 'md' 'tex' etc.

I am not well versed in lua and thus am having difficulty with checking whether the buf type is in the provided list of allowed filetypes.

AFAIK there's no built in way in Lua to check if element exists in a table. While there's no explicit in method in utils either you can use the set_of method there to do exactly that:

	condition = function(buf)
		local fn = vim.fn
		local utils = require("auto-save.utils.data")
		if
			fn.getbufvar(buf, "&modifiable") == 1
			and utils.set_of({'md', 'tex', 'org', 'txt'})[fn.getbufvar(buf, "&filetype")]
		then
			return true -- met condition(s), can save
		end
		return false -- can't save
	end,

You can check what set_of and not_in do here: https://github.com/Pocco81/auto-save.nvim/blob/main/lua/auto-save/utils/data.lua

So basically if one would add in method there it would look like this:

function M.in(var, arr)
	return M.set_of(arr)[var]
end

My file types are the full names for some reason, so I had to do like so (plus I wanted to NOT save instead):

and not utils.set_of({'md', 'markdown'})[fn.getbufvar(buf, "&filetype")]
