Available since LÖVE 0.9.0
It has been renamed from love.filesystem.enumerate.


Returns a table with the names of files and subdirectories in the specified path. The table is not sorted in any way; the order is undefined.

If the path passed to the function exists in the game and the save directory, it will list the files and directories from both places.

Function

Synopsis

files = love.filesystem.getDirectoryItems( dir )

Arguments

string dir

Returns

table files
A sequence with the names of all files and subdirectories as strings.

Function

Available since LÖVE 0.9.1 and removed in LÖVE 0.10.0
This variant is not supported in earlier or later versions.

Synopsis

files = love.filesystem.getDirectoryItems( dir, callback )

Arguments

string dir

A sequence with the names of all files and subdirectories as strings.

Examples

Simple Example

local dir = ""
--assuming that our path is full of lovely files (it should at least contain main.lua in this case)
local files = love.filesystem.getDirectoryItems(dir)
for k, file in ipairs(files) do
	print(k .. ". " .. file) --outputs something like "1. main.lua"
end

Recursively find and display all files and folders in a folder and its subfolders.

function love.load()
	filesString = recursiveEnumerate("", "")
end

-- This function will return a string filetree of all files
-- in the folder and files in all subfolders
function recursiveEnumerate(folder, fileTree)
	local filesTable = love.filesystem.getDirectoryItems(folder)
	for i,v in ipairs(filesTable) do
		local file = folder.."/"..v
		local info = love.filesystem.getInfo(file)
		if info then
			if info.type == "file" then
				fileTree = fileTree.."\n"..file
			elseif info.type == "directory" then
				fileTree = fileTree.."\n"..file.." (DIR)"
				fileTree = recursiveEnumerate(file, fileTree)
			end
		end
	end
	return fileTree
end
	
function love.draw()
	love.graphics.print(filesString, 0, 0)
