Greetings -
I’d been merrily downloading videos via extra/youtube until I got a
new MacBook Pro & too hastily upgraded to El Capitan. Among other
inconveniences I’ve had to work around because of SIP, the
``download-video’’
word now produces a permissions error:
———————————-
--- Data stack:
"FfViCWntbDQ"
IN: scratchpad download-video
Unix system call “open” failed:
Permission denied (13)
It was called with the following arguments:
"/Buckminster Fullers Jitterbug.mp4"
1537
438
———————————-
Digging into the code, I see that ``normalize-path’’ aims at the “/’’
mount-point
as the current directory for the Unix ``open’’. But SIP won’t allow
modifying
that location without authentication, so ``download-video’’ fails.
If I wrap the code in a ``with-directory’’ combinator setting an allowable
current directory, I’m back in business:
———————————-
IN: youtube
SYMBOL: my-youtube-prefix
my-youtube-prefix [ "/Users/cwalston/YouTube/videos" ] initialize
: download-video ( video-id -- )
[ my-youtube-prefix get ] dip ! ( -- path video-id )
[ get-video-info
[
video-formats [ "type" of "video/mp4" head? ] find nip
video-download-url
] [
"title" of sanitize ".mp4" append download-to
] bi
] curry with-directory ;
———————————-
It’s actually nicer to be able to set a target download directory, so I
should
thank SIP for goading me out of my laziness. I haven't hunted down all the
spots
where ``normalize-path’’ may choke on the strictures of SIP, but I suspect
this
isn't the last time El Cap will bite working code.
Cheers ~cw
