feature: Toggle command

[ionztorm]

Did you check the documentation?

• I have read all the docs

Is your feature request related to a problem? Please describe.

No problems, just a convenience. This is great by the way - I keep all my work in cloud storage so that I can access between devices without having to work with git when switching device. None of the existing solutions are able to detect changes to my files using this method, but your solution does work.

Describe the solution you'd like

It would be great if there was a command like :LivePreview toggle which turns it on if it's off, and turns it off if it's on so that we can bind it to a single key map.

Describe alternatives you've considered

The alternative is 2 key maps to start and stop.

Note, I have attempted to simulate this with my custom util table as follows:

M.live_preview_status = false

M.toggle_live_preview = function()
	if M.live_preview_status then
		vim.cmd("LivePreview close")
		M.live_preview_status = false
		print("LivePreview stopped")
	else
		vim.cmd("execute 'LivePreview start'")
		M.live_preview_status = true
		print("LivePreview started")
	end
end

However it doesn't load the browser immediately using this method. Instead it requires me to hit enter and then change window and then it loads the browser

update:

This works, but I have no idea how to code this in such a way that I could help you out with a PR

M.live_preview_status = false

M.toggle_live_preview = function()
	if M.live_preview_status then
		vim.cmd("LivePreview close")
		M.live_preview_status = false
		print("LivePreview stopped")
	else

		local filepath = vim.api.nvim_buf_get_name(0)

		if filepath == "" or filepath == nil then
			print("Error: No file detected for LivePreview.")
			return
		end

		local escaped_filepath = vim.fn.fnameescape(filepath)

		vim.api.nvim_feedkeys(":LivePreview start " .. escaped_filepath .. "\n", "n", false)

		vim.defer_fn(function()
			vim.cmd("redraw!")
		end, 100)

		M.live_preview_status = true
		print("LivePreview started for: " .. filepath)
	end
end

I just add a function require('livepreview').is_running() that you can use for it.

However, I'm not sure the use case of such toggle feature. live-preview.nvim would automatically close an existing server before starting a new one (possibly this should be documented)

[ionztorm]

Ahh if it does that automatically then no need thanks though!

So let me close this for now
