Hi folks,
I've posted a new gist for
spotlight.factor<https://gist.github.com/cwalston/7425403>w/ filename
& Factor formatting.
I think I dealt with most of Alex's red-lines, & I shed the string
constants.
The whole thing is much shorter. The included examples work on my machine.
The file can be USE:d from the listener if you give it a folder in your
'work'.
After a long divagation, looks like I've wound up back where John & Alex
suggested I start, 3 weeks ago. Well, like I was warned in the Boy Scouts,
when you wander lost in the woods, you tend to go 'round in circles.
Just couldn't see how to get on from there without a compass (or native
guides),
& I did learn a lot along the way. Still needs some improvement (maybe bug
fixes, too).
In particular, I'd like to memoize an API call to
MDSchemaCopyAllAttributes(),
but I'm better at Chinese than C. Pointers on alien-invoke, or what else to
use?
Thanks,
CW Alston
