Listing Save Files (Solved)

So, I'm working on making save files for my game. You choose singleplayer from the main menu, and the menu table gets repopulated with a list of existing save files, which will be .lua files that will overwrite the default player values. I have the following code:

Code: Select all

local filesTable = love.filesystem.enumerate("")
for i,v in ipairs(filesTable) do
	if love.filesystem.isFile(v) then
		table.insert(self.mainmenu, v)
	end
end

This works just fine, except that it also lists the contents of the root directory in the .love file (as it's supposed to, according to the documentation). Short of making a bunch of and not conditions, is there an easy way to not list the contents of my .love file?

Nope.

If we're thinking of the same thing,

Code: Select all

default={"main.lua","conf.lua","image.png"}
function checkIsDefault(f)
	for _,v in pairs(default) do
		if v==f then
			return true
		end
	end
	return false
end
local filesTable = love.filesystem.enumerate("")
for i,v in ipairs(filesTable) do
	if love.filesystem.isFile(v) and not checkIsDefault(v) then
		table.insert(self.mainmenu, v)
	end
end

I propose a simpler solution:

Code: Select all

local filesTable = love.filesystem.enumerate("")
for i,v in ipairs(filesTable) do
    if  v:find(".sav") ~= nil and love.filesystem.isFile(v) then
        table.insert(self.mainmenu, v)
   end
end

Assuming save-files have the extension '.sav'

Or, even better, putting all save games in a dedicated subfolder. (You know, like "saves/".)

Don't be ridiculous.

I vote for this solution!

I tried before posting, but received the following results:

Code: Select all

local filesTable = love.filesystem.enumerate("saves/")
for i,v in ipairs(filesTable) do
	if love.filesystem.isFile(v) then
		table.insert(self.mainmenu, v)
	end
end

Returns nothing.

Code: Select all

local filesTable = love.filesystem.enumerate("saves")
for i,v in ipairs(filesTable) do
	if love.filesystem.isFile(v) then
		table.insert(self.mainmenu, v)
	end
end

Returns nothing.

Code: Select all

local filesTable = love.filesystem.enumerate("/saves")
for i,v in ipairs(filesTable) do
	if love.filesystem.isFile(v) then
		table.insert(self.mainmenu, v)
	end
end

Returns nothing.

Code: Select all

local filesTable = love.filesystem.enumerate("/saves/")
for i,v in ipairs(filesTable) do
	if love.filesystem.isFile(v) then
		table.insert(self.mainmenu, v)
	end
end

Returns nothing.

Code: Select all

love.filesystem.setIdentity("kurosuke/saves")
local filesTable = love.filesystem.enumerate("")
for i,v in ipairs(filesTable) do
	if love.filesystem.isFile(v) then
		table.insert(self.mainmenu, v)
	end
end

Returns everything in the root directory (of the save folder and .love file) as well as the saves directory.

Code: Select all

love.filesystem.setIdentity("/saves")
local filesTable = love.filesystem.enumerate("")
for i,v in ipairs(filesTable) do
	if love.filesystem.isFile(v) then
		table.insert(self.mainmenu, v)
	end
end

Returns the root but not the saves directory.

Anyone care to explain what I'm doing wrong, because I don't see it. The old "bash-head-on-keyboard" strategy of coding is letting me down. (and yes, I am sure that the folder and files are there and named correctly... the returns-too-much result confirms that.)

I would like to use a save folder, because I'm already storing some configuration settings in the root of the save area, but with the above code refusing to cooperate...

Code: Select all

love.filesystem.setIdentity("kurosuke/")
local filesTable = love.filesystem.enumerate("saves")
for i,v in ipairs(filesTable) do
   if love.filesystem.isFile(v) then
      table.insert(self.mainmenu, v)
   end
end

(and of course, make sure you have something in the saves folder before testing)

Still no dice. Just replicated the results on another machine too, so I doubt it's my desktop...
