Getting close to the 1.0 release of the metadata library.
If there are no major problems with this release candidate, that is.

Thanks, fixed. Along with extracting more metadata from .torrents
and handling flacs with id3 tags better.

In short, no (to both).
In earlier messages I asked for a gem too, and it turns out this is hard to do
because of a python script that's included. And as far as windows, I think a
lot of this relies on shelling out, which windows... doesn't have. So you
might look for another solution (or go to \*nix).

If there's a way to install bin/chardet as-is, now gem adds
"#!/usr/bin/ruby"-boilerplate (which doesn't quite work for a
python script.) ...Though, I could always turn it into a ruby script
that executes a bit of python. So, yeah, it is possible. I'll build one.
> will this run on windows?
In theory. At least the Ruby parts (i.e. wma, flac, mp3, torrents.)
No idea if you can get the external programs and libs installed and
running, sounds unlikely. But hey, feel free to prove me wrong 🙂

Oh, and, if there are any other filetypes that could do with more
metadata, feel free to request. Especially if some other program
shows it. And still more especially if the other program is a
cmdline app with a debian package 😉

Or, one could make a VMWare image or somesuch and use it as a
metadata appliance. Anyone know how that might work best?

Or perhaps build the external programs with cygwin?
(I think most cygwin programs only depend on cygwin1.dll which is
about 1.2 meg on my system.)

interesting, i didn't know that. So what is the minimum set of files needed to run cygwin? i'm asking since i haven't used one for a long long time now..
kind regards -botp

It depends. (lol, pun not intended, but my next sentence was going to involve
depend.exe)
Er... using depends.exe [1] one can view a tree of dependencies for a .exe or
.dll file (among other object formats.)
A number of cygwin-compiled binaries only depend on cygwin1.dll. (Not
counting windows modules like kernel32.dll.)
To verify this, I was successfully able to copy just cygwin1.dll and
cygwin/bin/ftp.exe into a subdirectory elsewhere, and change the shell
execution path to simply ".", and the program worked.
Other binaries, like cygwin/bin/ls.exe, required a couple extra .dll's
(in this case for handling character set encodings) like cygintl-3.dll and
cygiconv-2.dll
A more complex program like cygwin/bin/wget.exe still had minimal
and reasonable dependencies: character set handling and crypto
libraries:
cygwin1.dll, cygintl-3.dll, cygiconv-2.dll, cygcrypto-0.9.8.dll, cygssl-0.9.8.dll
So it appears the cygwin folks have done a nice job at avoiding
dependency bloat.
