That's a bad assumption, you should always clean up after yourself.

OK, I had overlooked the fact that cleanup is important to you, which
makes sense for security and to save disk space early.
TempFile, TempDir don't do the cleanup, but the OS will sooner or later.
Here is my new suggestion for a file
<http://www.programming-idioms.org/idiom/138/create-temp-file/1751/go>
and for a dir
<http://www.programming-idioms.org/idiom/139/create-temp-directory/1757/go>
:
tmpfile, err := ioutil.TempFile("", "")
checkerr(err)
defer os.Remove(tmpfile.Name())
dir, err := ioutil.TempDir("", "")
checkerr(err)
defer os.RemoveAll(dir)

That's my current code, I just wanted to double check that it's
the proper one (ie that the cleanup actually happens), since some
of my temp files can be fairly large.

I suggest you don't bother with cleanup. It should work on
any OS.

I have a tool that generates some HTML and launches a web
browser to display it. For this to work, I need to save
the HTML some place and I also need to handle the file
afterwards. The app itself doesn't persist - it generates
the content and exits. There are thus two issues I'm
struggling with:
1. What is the best place for this? Do I create a folder
in usr.HomeDir()/.appname/ and place HTML files there? Or
do I just create tempfiles in os.TempDir? Does it make a
difference?
2. How do I clean up? As I said, the app does not persist
(so I can't defer os.Remove), so either I scan the folder
in question (before my HTML generation) and remove all
files older than, say, a day. Or is that done for me by
the operating system if I use os.TempDir?
I thought I'd just use os.TempDir and let the OS handle
it, but I'm not 100% sure the OS does clean this up on its
own. (This will be used on Windows and Macs, maybe Linux.)
Any insight on any of these would be greatly appreciated.
Thanks!
