in thread Programs that write programs

<snark>

$ perl -e'' No code specified for -e.

</snark> :)

Update: Hm, seems to work fine with a file:

$ perl -w /tmp/empty.pl

Update 2: Nevermind, moritz is a clever boy, and laziness (leaving out whitespace) is not always a virtue.

Update 3: I think I prefer the symmetry and perl purity of: echo -n | perl | perl | perl | echo -n

Good Day,

    Ah, but if it outputs nothing, how can you then run that nothing? In other words, outputting nothing, is the same as not outputting anything. Surely that's a no-program. Hrm... I wonder if it's considered a element in the set of all possible quines or not.

[ambrus]: ah, it's one of thos
[Eily]: what, there's a difference between proof of concept and production?
[LanX]: 20 years ago traders were complaining about the latency of the trading system...
[ambrus]: I'm currently in the process of rewriting my proof of concept programs. They sort of developped organically as I was experimenting, so now I've got an ugly mess of multiple programs and one-liners held together by nothing. I'll have to rewrite them to som
[ambrus]: ething that's both cleanly organized and mostly automated.
