Micro plugin with fzf and fasd

I am trying to mod. this script (see at bottom)

to use this command fasd -flt | tail -n 25 | grep -Ev '\.(tiff|jpg|jpeg|png|gif|pxm|mp3|mp4|aac)$' | fzf --tac

Instead of just straight fzf

I use fasd to list recently opened files/documents/code etc (media is excluded) via fzf and open them in micro.

I want to access this while in micro.

The commands in this script are will be the same except prefixed by an 'r'. so rfv = recent file / split vertical.

I hope this make sense.

I have tried changing the command in line 9, but a error flashes up and its far to quick to read.

VERSION = "1.0.0"

local micro = import("micro")
local shell = import("micro/shell")
local config = import("micro/config")
local buffer = import("micro/buffer")

function fzf(bp, opt)
	local output, err = shell.RunInteractiveShell("fzf", false, true)
	if err ~= nil then
	    micro.InfoBar():Error(err)
	else
	    fzfOpen(output, bp, opt)
	end
end

function fzf_find(bp, args, opt)
	local strings = import("strings")
	local cmd = "grep --line-buffered -rnwi "

	local pattern = ""

	for i = 1, #args do
		pattern = args[i] .. " "
	end

	cmd = cmd .. pattern .. " * | fzf"
	
	local output, err = shell.RunInteractiveShell(cmd, false, true)
	-- local run, err = shell.RunBackgroundShell(cmd)
	-- local output = run()
	
	if err ~= nil then
	    micro.InfoBar():Error("could not execute fzf command: ", err)
	    return
   	end

	-- output = strings.Split(output, "\n")
	-- micro:TermMessage("\nOutput\n", output)
	
	local input = strings.Split(output, ":")

	if #input < 2 then
	    micro.InfoBar():Error("bad input format: ", input)
	    return
   	end
   	
	fzfOpenLine(input[1], bp, 2, input[2])
	micro.InfoBar():Message(input[1] .. " @ " .. input[2])
end

function fzfOpen(output, bp, opt)
    local strings = import("strings") 
    local strconv = import("strconv") 
    file = strings.TrimSpace(output)

	if file ~= "" then
		local buf, err = buffer.NewBufferFromFile(file)

		if err ~= nil then
			micro.InfoBar():Error(err)
		end

		if opt == 0 then
			bp:OpenBuffer(buf)
		elseif opt == 1 then
			bp:HSplitBuf(buf)
		elseif opt == 2 then
			bp:VSplitBuf(buf)
		end
	end
end

function fzfOpenLine(output, bp, opt, line)
    local strings = import("strings") 
    local strconv = import("strconv") 
    file = strings.TrimSpace(output)

	if file ~= "" then
		local buf, err = buffer.NewBufferFromFile(file)

		if err ~= nil then
			micro.InfoBar():Error(err)
		end

		local new_bp

		if opt == 0 then
			new_bp = bp:OpenBuffer(buf)
		elseif opt == 1 then
			new_bp = bp:HSplitBuf(buf)
		elseif opt == 2 then
			new_bp =bp:VSplitBuf(buf)
		end

		new_bp.Cursor.Y = tonumber(line)-1
		new_bp.Cursor:Relocate()
	end
end

function init()
    config.MakeCommand("f", function(bp, args)
		fzf(bp, 0)
    end, config.NoComplete)

    config.MakeCommand("fh", function(bp, args)
		fzf(bp, 1)
    end, config.NoComplete)

    config.MakeCommand("fv", function(bp, args)
		fzf(bp, 2)
    end, config.NoComplete)

    config.MakeCommand("ff", function(bp, args)
		fzf_find(bp, args, 2)
    end, config.NoComplete)

    config.AddRuntimeFile("fzf", config.RTHelp, "help/fzf.md")
end

Getting this to work would make it, in my eyes, the perfect (user friendly) cli editor

Start from the embedded Lua plugin script, especially the fzf command in line 9, and reproduce the reported error while running the fasd pipeline. Done means the recent-file command works inside micro, excludes the listed media extensions, and supports the requested r-prefixed commands for opening files and splits.
