Require all files in a directory

[Psyk]

How would I require all files in a directory?

Entities - Folder
entity.lua
potion.lua

Would I be right if I did this?

Code: Select all

function includeAllEnts() 
     local directory = "entities"
     local entities = love.filesystem.enumerate(directory)
     
     for i, e in ipairs(entities) do 
      require(e)
     end
end

Untested, but I'd say:

Code: Select all

function includeAllEnts() 
     local directory = "entities"
     local entities = love.filesystem.enumerate(directory)
     
     for i, e in ipairs(entities) do 
      require(directory .. "." .. e)
     end
end

      require(directory .. "." .. e)
     end
end

I get the lua error attempt to call field 'enumerate' a nil value.

Hey there, enumerate() was renamed to love.filesystem.getDirectoryItems().

Maybe this will help you too:

Thanks for letting me know that the enumerate function was renamed!

I thought of something else that works the same and gets the job done. Thanks for your help!

Working Code:

Code: Select all

require "love.filesystem"

function includeAllEnts()
	local dir = "entities"
	local entities = love.filesystem.getDirectoryItems(dir)

	for k, ents in ipairs(entities) do
		trim = string.gsub(ents, ".lua", "")
		require(trim)
	end
end

[undef]

Shouldn't it rather be:

require(dir .. "/" .. trim) in this code:

Code: Select all

function requireDirectory( dir )
   dir = dir or ""
   local entities = love.filesystem.getDirectoryItems(dir)

   for k, ents in ipairs(entities) do
      trim = string.gsub( ents, ".lua", "")
      require(dir .. "/" .. trim)
   end
end

Otherwise this should only require all files in the root directory, if I'm not mistaken.
I also think passing the directory as a parameter is convenient.

You don't need to require love.filesystem as well, all love modules are loaded unless deactivated in the config file.
