Hi,
What's the current official position on how to create
temporary files for use during a unittest. I found
https://github.com/dlang/phobos/pull/5788
but it seems to be languishing in the "we have discussed all
the issues that no-one will ever have a problem with" phase.
What to do between now and when there is an LDC release that
has the result of
the merge?
You could use libc's tmpfile with std.stdio.File until a D
alternative pops up.
http://en.cppreference.com/w/c/io/tmpfile
I've had no idea C++'s got this in the standard library lol a
while ago I ended up doing this (on Windows):
/// Creates a uniquely named, zero-byte temporary file on disk
and returns the full path of that file.
/// Returns: the full path of the temp file.
string tempFilename()
{
import core.sys.windows.windows : GetTempFileNameW, MAX_PATH;
import std.file : tempDir;
import core.stdc.wchar_ : wcslen;
import std.windows.syserror : wenforce;
import std.conv : text, wtext;
wchar[] path = new wchar[MAX_PATH+1];
string dir = tempDir;
wenforce(GetTempFileNameW(dir.wtext.ptr, // temp path
("tmp"w).ptr, // dir
prefix
0, // id generated
internally
path.ptr // path
buffer
),
"GetTempFileName()");
return path[0 .. wcslen(path.ptr)].text;
}
It's windows-only and call GetTempFileNameW actually so just a
function wrapper to work with D. There's a way to MAX_PATH but I
didn't care to implement at time...
