Thanks for the idea. I’ll look for HOME first followed by USERPROFILE
before failing with a better message than that :slight_smile:

%HOME% is not reliably set. Some OSes will make it a combination of
%HOMEDRIVE%%HOMEPATH%, but many don’t (it’s not set on my Vista x64 box,
for example).

A much more reliable environment variable seems to be %USERPROFILE%.

(See full trace by running task with --trace)

Taking a look at the rakefile,

SPEC_HOME = ENV[‘HOME’].gsub(‘\’, ‘/’) + ‘/dev’

So the problem is that I don’t have a HOME variable set. Am I unusual
in this respect? Do most people have this set on their Windows machines
by default?

I would bet that some of the specs themselves assume that HOME is
defined as well.

I have already hacked a couple of them to make them look for the HOME
then USERPROFILE. That’s a relic of the spec’s being developed mostly on
*nix.

Peter Bacon D.:

How conventional in the Ruby World in general is it to expect the HOME
variable to exist?
Wouldn’t it be easier to have a check at the start of the RakeFile and
spec_runner.rb that creates the HOME variable (from USERPROFILE, etc)
if it is nil? Then you don’t need to go and hack the specs themselves.

In the new world, we’ll likely have to modify the mspec spec runner and
contribute the changes back to the mspec project. specrunner.rb and
friends are effectively deprecated today.

Thanks,
-John

Or add the HOME logic to irvars.bat

That only works for IronRuby but not for running the Rakefile under
CRuby.

It seems like it should be a separate environmental thing though. I
would
have the rakefile itself define HOME based on USERPROFILE if it doesn’t
exist then. I’d rather not see something like that put into the specs
themselves.

Yep that was my point. Do the same thing in the spec_runner.rb or
whatever
file replaces it in the New World.

Actually, a better place in either case is spec_helper.rb. That way it
doesn’t depend on the runner, and once we are able to run files
directly, they will get the var too.
