I have a question:

What exactly does that bit of obfu do?

Hi,

Brilliant idea, thanks!

apt-sary-mksary

This fails here with the following message:

— snip —
head -100 | egrep -B100 ‘^FILE +LOCATION’ > header.txt
rake aborted!
Command failed with status (): [head -100 | egrep -B100 ‘^FILE
+LOCATION’…]
— snip —

Could you update apt-sary-mksary to skip generating a contents sary when
there are no contents files? I’ve written my own patch (don’t actually
do
anything in the rule if `cat’ ends up being nil) but it looks fairly
ugly to me.

Something like obfuscator generator?

Hi,

Please try this patch.

that’s about what I did myself, and it works fine. So as it seems you
wouldn’t do it differently, I suggest you include it in the next
release.

I’m still overjoyed by the speedup, by the way. Thanks again, I guess.
:wink:

(By the way, I just tried downloading and saryfying the contents
database.
Takes its sweet time, doesn’t it?)

As suggested, it generates obfuscated code that outputs a given string,
formatted to make it suitable for e-mail signatures. I’m way too lazy to
write my obfuscated signatures myself. :wink:
