    LFS ACCESS USER DOCUMENT FOLDER

    edited March 2020 in General questions
    How are you all doing?
    I have a question please. Is it possible to know the path of the user pictures folder?
    for example: C:\Users\USERNAME\Pictures\
    I would like to use the RenderTarget:save(filename,x,y,width,height) function.
    Do you think lfs can do it?
    Thank you very much for your help.

      that's very handy, thanks for pointing out.
      does one of these refer to the 'root' directory on an android phone? (where usually apps put their own folder to store public stuff related to the app)

      They are only working on QT based exports I am afraid

      would be nice to associate some of them with folders on android as well, if that's possible. or have separate names for android folders, e.g. to root, download, dcim, sdcard root.

      for android you can do it via media plugin. I will post an example later on today.

      using the gmedia plugin you can change the folder you want to save on android.
      You need to modify the java code (don't worry it's easy):
      1- go to gideros installation folder and gmedia plugin:
      C:\Program Files (x86)\Gideros\All Plugins\gmedia\bin\Android\src\com\giderosmobile\android\plugins\media

      2- open GMedia.java (notepad++) and go to line 141

      3- by default the path is: SDCARD/Pictures you can change it!

      4- FOLDER NAME: line 143, you can change "/GIDEROS" folder name to something else (your app name)

      5- FILE NAME: line 144, you can change "img_" + timeStamp + ".png" to something else

      6- SAVE THE JAVA FILE

      7- RE-EXPORT YOUR APP

      It's quick and dirty but it works. You have to do the change for each of your apps you want to save to android.

      an example for the original question:
      function Tile:saveTile()
	-- CURRENT DATE AND TIME
	local myyear = os.date("*t").year
	local mymonth = os.date("*t").month; if mymonth < 10 then mymonth = "0"..mymonth end
	local myday = os.date("*t").day; if myday < 10 then myday = "0"..myday end
	local myhour = os.date("*t").hour; if myhour < 10 then myhour = "0"..myhour end
	local mymin = os.date("*t").min; if mymin < 10 then mymin = "0"..mymin end
	local mysec = os.date("*t").sec; if mysec < 10 then mysec = "0"..mysec end
	local mytime = myyear..mymonth..myday.."_"..myhour..mymin..mysec
	-- save
	if application:getDeviceInfo() == "Android" then
		mediamanager:postPicture("|T|mytile"..g_tilesize..".png")
	else
		local lfs = require "lfs"
		lfs.chdir(application:get("directory","download"))
		local dir = lfs.currentdir().."\\"
		self.mytilert:save(dir.."mytile"..g_tilesize.."_"..mytime..".png")
	end
end

      @MoKaLux as a suggestion, add pcall() to prevent app from crushing if something went wrong. Something like that:
      local TestClass = Core.class(Sprite)
function TestClass:init()
	local gfx = Pixel.new(math.random(0xffffff),1,32,32)
	gfx:setAnchorPoint(.5,.5)
	self:addChild(gfx)
end
-- methodName (string): name of the method that will be safely called
-- ... - arguments for that method
function TestClass:tryCatch(methodName, ...)
	local status, error = pcall(self[methodName], self, ...)
	if not status  then 
		print(error) -- error is a string
		-- if you are using "error" function, you can do something like that:
		-- error({code = 404, message = "Page not found"}) 
		-- print(error.code, error.message) --> "404 Page not found"
	end
end
 
function TestClass:doStuff()
	for k,v in ipairs(nil) do end
end
 
local obj = TestClass.new()
obj:setPosition(application:getLogicalWidth() / 2, application:getLogicalHeight() / 2)
stage:addChild(obj)
 
-- instead of calling "doStuff" method directly, use tryCatch method to safely call
-- code that can possibly crush the app
obj:tryCatch("doStuff") -- main.lua:17: bad argument #1 to 'ipairs' (table expected, got nil)
 
-- just an animation to show that app is still runing
local anim = MovieClip.new{
	{1,60,obj, {scale = {1, 0.7, "outBack"}, rotation = {0, 90, "linear"}}}
}
anim:setGotoAction(60,1)
