rindolf: is not { my $c=0; sub getNext { $c++ } } a perfectly good way to do a closure on a variable (that should not be seen by anything other than that sub, sort of like that PHP example with the "static" var <http://www.phpsadness.com/sad/18> and I think similar to static vars in C++ and Java) ? |
| rindolf |
ncow: yes, it is. |
| uri |
ncow: you can use state vars in recent perls too |
| ncow |
but I keep thinking there was a way of doing it with outer and inner subs too, or no |
| rindolf |
ncow: thing is in sub outer { my $c = 0 ; .... } the $c is temporary. |
| ncow |
uri: yeah I just saw that in perlfaq7 just before you said that, thanks though :) |
| rindolf |
ncow: which causes weird side-effects with a package-scope inner sub. |
| ncow |
rindolf: but shouldn't the inner sub have a closure over $c though? |
| rindolf |
ncow: it will. |
| rindolf |
ncow: but every time you call outer() you get a different $c. |
| apeiron |
Windows also accepts a sledgehammer to the harddrive. |
| ncow |
rindolf: I'm talking about calling the inner one |
| ncow |
rindolf: could be interesting to call the outter one to re-prime or something (just kind of thinking aloud, I could be completely wrong) |
| ncow |
(please let me know if I am) |
| cj |
Botje: that's not the point. Some systems don't :) |
| rindolf |
apeiron: Windows requiring doing a SOAP request to a .NET service (that is very picky about its scope) to call an OLE component for writing an Excel macro to do that. |
| apeiron |
And for those we have File::Spec. |
| rindolf |
apeiron: it's not as straightforward as in UNIX. |
| ncow |
I think I found a mis-type in perlfaq7 <http://perldoc.perl.org/perlfaq7.html#How-do-I-create-a-static-variable%3f>, under "How do I create a static variable?" |
| ncow |
It says: sub counter { state $count = 1; $counter++ } |
| ncow |
I think that should be $count++ not $counter++ |
| rindolf |
apeiron: http://www.shlomifish.org/humour/fortunes/show.cgi?id=joel-forum-unix-shooting-in-the-foot |
| rindolf |
ncow: yes, it should. |
| rindolf |
ncow: or "$state $counter = 1;". |
| ncow |
rindolf: oh shit, that is so true. I hate ActiveX like the mf-ing plauge |
| ncow |
rindolf: yes, though counter is the sub's name, I think the var was meant to be called $count |
| ncow |
as in the count that the counter counts :) |
| rindolf |
ncow++ |
| rindolf |
ncow: it still exists in my github fork of the perl-doc-cats repo. |
| ncow |
a counter doesn't counter counters unless it is in fact a counter counter :) |
| uri |
ncow: go back to sesame street! |
| ncow |
lol |
| uri |
it seems to be where you learned your perl! |
| uri |
use Big::Bird; |
| ncow |
but does a counter counter count it self as a counter counter? |
| uri |
that is counterproductive thinking |
| ncow |
(or does it just consider itself a cunt and thus only count it self as a cunt counter since it only counts cunts?) |
| ncow |
ok I think I'm done with that one... |
| ncow |
sorry, when ever someone mentions ActiveX it makes me all twichy, and if there is no one around to choke into submition, I tend to write odd things, like a ram memory discharge |
| Khisanth |
a CounterCounterFactoryCounter |
| szr |
ActiveX will do that |
| rindolf |
ncow: heh. |
| rindolf |
ncow++ |
| ncow |
ooooh now we're talking |
| rindolf |
ncow: anyway, how do you want to be credited in the commit log? |
| uri |
rindolf: call him the miscount |
| rindolf |
uri: heh. |
| ncow |
you don't have to do that, but if you really want to, ncow is fine. Necrocow may be me old moniker (and freenode account name) but ncow is what I've been going by for quite a while now |
| rindolf |
uri: Count von Counter |
| ncow |
so I'm the count of miscountistu? |
| rindolf |
ncow: pushed. |
| ncow |
cool |
| ncow |
glad I could help. |
| rindolf |
ncow: you're welcome. |

“One Perl One-Liner, Two Perl One-Liners, Three Perl One-Liners. <Thunder and Lightning> Ha ha ha ha ha ha.” |

-- Count von Counter |
| ncow |
rindolf: haha |
| ncow |
rindolf: god I still remember that from when I was a kid watching PBS |
| rindolf |
ncow: I remember it from the Israeli Sesame Street. |
| ncow |
Israeli? didn't know they had their own version |
| rindolf |
ncow: they call him there "Mar Soffer." - "Mr. Counting" |
| rindolf |
ncow: we actually had two at two different times. |
