how use the love.filesystem

[sky2046]

I recently encountered some difficulties when i create a log file and directory.
why did i call the function[love.filesystem.createDirectory] failed， the following show code.

Code: Select all

logDir = "./log"
logPath = "./log/sad.log"

function love.load()
   loadStatus, errString = initLog()
end

function love.draw()
    if (false == loadStatus) then
        love.graphics.printf("progress load fail:\r\n \t" .. errString, 0, 0, 1024, "left")
    end
    
end

function love.update(dt)

end

function initLog()
    cwd = love.filesystem.getWorkingDirectory()
    if ("/" ~= string.sub(cwd, -1, -1)) then
        cwd = cwd .. "/"
    end
    
    if ("./" == string.sub(logDir, 1, 2)) then
        logDir = cwd .. string.sub(logDir, 3)
    end
  
    if (nil == love.filesystem.getInfo(logDir, "directory")) then
        if (false == love.filesystem.createDirectory(logDir)) then
            return false, "can not create directory[" .. logDir .. " ]"
        end
    end
    
    
    if ("./" == string.sub(logPath, 1, 2)) then
        logPath = cwd .. string.sub(logPath, 3)
    end

    if (nil == love.filesystem.getInfo(logPath, "file")) then
        logFile = love.filesystem.newFile(logPath)
        if (false == logFile:open("r")) then
        	return false, "can not create file[" .. logPath .. " ]"
        end
    end
end

You can only write to the save directory. It is different from the working directory, and the only control you have over it is setting its name (not path/location) through the game's identity. This is all explained here.
