Describe the question

I would love to know how to turn a shell command with a pipe into the arguments of the Lua function Command.

I can create some easy plugins by using the default plugins as template and adapting the argument of the Command function, but I only know how to do this for a simple shell command and its arguments.

As soon as I want to turn a shell command with a pipe into a plugin, I am stuck and I could not find the answer by myself.

For example, I would like to bind the following to a kbd:

fd -d 1 | fzf

to jump to a dir/file in CWD non recursively, but the pipe blocks me.

Thank you very much for your help and your time (and for yazi: it is so cool 🙂 )

Anything else?

I'm still learning, so someone else might be able to give you better feedback. But for the use case you described, I would write something like this:

local function fail(s, ...)
	ya.notify { title = "my_plugin_name", content = string.format(s, ...), timeout = 5, level = "error" }
end

local function entry(_)
	local _permit = ya.hide()
	local cmd_args = "fd -d 1 | fzf"

	local child, err = Command("sh")
		:args({ "-c", cmd_args })
		:stdin(Command.INHERIT)
		:stdout(Command.PIPED)
		:stderr(Command.PIPED)
		:spawn()

	if not child then
		return fail("Spawn command failed with error code %s.", err)
	end

	local output, err = child:wait_with_output()
	if not output then
		return fail("Cannot read command output, error code %s", err)
	elseif not output.status.success and output.status.code ~= 130 then
		return fail("Spawn command exited with error code %s", output.status.code)
	end

	local target = output.stdout:gsub("\n$", "")

	if target ~= "" then
		local is_dir = target:sub(-1) == "/"
		ya.manager_emit(is_dir and "cd" or "reveal", { target })
	end
end

return { entry = entry }

Please note that local is_dir = target:sub(-1) == "/" is a somewhat hacky way to determine whether the target is a directory.

Ah cool! Thank you very much lpnh! I truly appreciate your time.

Good idea to pass the piped commands as arguments to sh -c. I hadn't thought of that.

I will give this a try.

This works beautifully!!! Thank you again! ❤️
