Hi Marinersk

I've managed to solve this now using awk instead. I know its not perl but for those interested here is how I did it.

#!/usr/gnu/bin/gawk -f BEGIN { OFS=FS="," } { com="xchop -d, group.csv " $1 while ((com |getline res) > 0) { if (split(res,arr) > 1) print $2,arr[2] } close(com) }
xchop is a C written function that acts as sort of a binary chop for strings.

Thanks Jim

[ambrus]: Also, I was wrong, apparently you have to support both periodic and one-shot timers in an AnyEvent backend
[Corion]: ambrus: That looks deceptively simple, but maybe that's simply all that's needed. Which would be great! I hope I get to test it tomorrow, thanks!!
[choroba]: Hm, unrelated question.
[ambrus]: I added a timer implementation to ambrus's scratchpad as well, again the whole thing is completely untested and probably has more bugs than lines
[choroba]: Anyone using anything to validate json contents of a REST service?
[moritz]: choroba in python I use jsonschema
[moritz]: I'm sure there's a Perl implementation of it too
[choroba]: it seems Kelp and similar help you a lot with dispatching, but how to do something similar with contents?
