Not needed! Bob Faist responded to my email and updated both his git repo and CPAN to WS::MB 0.94, under which those tests that were failing reliably now succeed.

(I didn’t dig too deeply into the diffs, but it looks like the tests were failing because the MB data for the specific “Releases” he was checking against had been altered some time in the past 6 years. I guess maybe if I were MB, I’d have some immutable records in my DB that were intended to be used for people to validate their applications’ functionality against the MB API but, hey, whatever.)

It may make sense for us to collaborate off the list for that, but here’s the short version of things I have pinned in abcde.conf that are Mac OS X-related, rather than personal preference (I think I see the right places make these things the OS-dependent defaults, and I’ll send you patches through the normal channels):

# default abcde curl opts leave out -L, but without it curl doesn’t
# follow redirects, and like 90% of coverartarchive.org is redirects,
# because edge routing

# abcde won't try to use $DISPLAYCMD without $DISPLAY being set to
# *something*, because X11, but we can do native GUI without paying
# any attention to that environment variable
# for checking album art in Preview.app
# to just "reveal" in the Finder rather than open in Preview

I played around with triggering Mac OS X’s “Quick Look” from the command line (what you get on a Mac if you tap “space” on, say, an image file) and you *can* do that, through `qlmanage -p`, but that wasn’t ever really intended as an end-user tool, it spits a bunch of garbage to STDERR, and if you do something horrible like feed it a 0-byte file it’ll crash out silently and hang around in the background indefinitely. So… maybe don’t do that. The one up side is that you can just hit “escape” and close the pop-up, without leaving another GUI app running, and without having to context-switch back to the terminal where you’re running abcde but… eh. Doesn’t really seem worth it to me, especially not as a default.

Sure, will do. I’m going to maybe go through the motions of making at least the MacPorts version of abcde happier by default before writing a bunch of stuff up, since I’d just go change it afterwards. I could certainly toss those couple of abcde.conf items there, though.

Unless I’m totally ignorant of how MoinMoin works, I think you’ve just got the front page there right now. Do you have any theoretical organization structure in mind for OS-specific tips?

I’m going to take a look at that this afternoon. I *think* it’s totally trivial, but I haven’t actually tried yet, so...
