Hi,

== Abstract

Sary makes `apt-cache search' and `apt-file search’ MUCH FASTER.  
Using apt-sary is very easy!  
Only replace `apt-' with `apt-sary-'.

It is available at  
[http://www.rubyist.net/~rubikitch/computer/apt-sary/index.en.html](http://www.rubyist.net/~rubikitch/computer/apt-sary/index.en.html)

== What’s new

=== [2005/12/21] 0.1 released  
Initial release

== Install  
Please execute the following commands.

apt-get install rake sary apt apt-file  
ruby -ropen-uri -e  
‘URI(“[http://www.rubyist.net/~rubikitch/archive/apt-sary-0.1.tar.gz](http://www.rubyist.net/~rubikitch/archive/apt-sary-0.1.tar.gz)”).read.display’

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.  
😉

(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. 😉
