Hi, I am creating a OS but the way I would like to do it is have a startup that downloads separate files to build a OS computer instead of one program. I have made the startup program below but it does not write the files.

Spoiler


home = fs.open("home", "w")
login = fs.open("login", "w")
new = fs.open("new", "w")
function getn()
    http.request("http://pastebin.com/raw.php?i=7Ksbviwh")
    requ = true
	    while requ do
		    local event, url, scourceText = os.pullEvent()
		    if event == "http_success" then
			    newf = scourceText.readAll()
			    new.write(newf)
			    print("Downloaded New")
			    getl()
		    else
			    print("Failed To Download New")
			    sleep(2)
			    os.reboot()
		    end
	    end
end
function getl()
    http.request("http://pastebin.com/raw.php?i=cs5C13Hg")
    requ = true
	    while requ do
		    local event, url, scourceText = os.pullEvent()
		    if event == "http_success" then
			    loginf = scourceText.readAll()
			    login.write(loginf)
			    print("Downloaded Login")
			    geth()
		    else
			    print("Failed To Download New")
			    sleep(2)
			    os.reboot()
		    end
	    end
end
function geth()
    http.request("http://pastebin.com/raw.php?i=FUB6hDDB")
    requ = true
	    while requ do
		    local event, url, scourceText = os.pullEvent()
		    if event == "http_success" then
			    homef = scourceText.readAll()
			    home.write(homef)
			    print("Downloaded Home")
			    shell.run("new")
		    else
			    print("Failed To Download Home")
			    sleep(2)
			    os.reboot()
		    end
	    end
end
function is()
    if not fs.isDir("user_stats") then
	    getn()
	    shell.run("new")
    else
	    shell.run("login")
    end
end
is()

Why don't you use the pastebin program ?

Take a look at /rom/programs/http/pastebin ! ;)/>

I don't want the people to have to pastebin multiple programs. I want them to pastebin one and that gets the rest.

You want your program to install files you already posted on pastebin isn't it ?

I think you can try something like that :


shell.run("pastebin", "get", "7Ksbviwh", "new")

It is an example. This will run the pastebin program but from your own program. User only launch the program you wrote in first post.

Here is a basic script that should work:


function download(url, file)
  local content = http.get(url).readAll()
  if not content then
    error("Could not connect to website")
  end
  f = fs.open(file, "w")
  f.write(content)
  f.close()
end

That should work. Wrote it in under a minute.

*cough* forgetting to close the http file handle, and no localized file handle *cough*

you dont need to close the http handle, its not a real file handle
