wongon	To get the last index of an array @a, it's $#a.  If I've got a scalar, $ar, that is a reference to an array @a, how do I get the last index through $ar?  What is the syntax?

ScHAmPi	well I'm not gonna bother, it makes no sense, and I can only study this perl stuff tonight
ScHAmPi	tomorrow I gotta start studying my theoretic part

spectre^	I'm invoking a perl script from another perl script via system(), and, in the invoked script I'm using exit 1; to return a 1 to the invoking script, but I keep getting a 255 in $? >> 8, when I expect a 1
spectre^	I think I'm doing something wrong
spectre^	What can I do to get the exit status to return  a 1?
PerlJam	spectre^: perldoc -f system  # it tells you in the docs
PerlJam	oh.  /me should have read up a few lines.
PerlJam	spectre^: show your code somewhere.
spectre^	I think that exit must return 255 to the shell on error, as indicated by 1
spectre^	I guess?
icke	looks like it was killed
spectre^	http://pastebin.com/m1e803053
buubot	spectre^:  The 19 line paste m1e803053 has been copied to http://erxz.com/pb/22638  .
spectre^	Nice bot
spectre^	I think that's enough to show you what I'm doing
spectre^	printf("NOTICE gsum returned: %d\n", $?>>8); always shows the value as 255
icke	does it even execute? check $? for -1 before
spectre^	While I can certainly work with that if it's behaving as intended

Action: GumbyPAN CPAN Upload: Text-vCard-2.05 by LLAP
spectre^	Yeah
spectre^	I get the error
icke	what error?
spectre^	The printed error from the calleee
spectre^	I didnt bother checking for -1 because I saw the error
spectre^	Make sense?
DrForr	spectre^: $? may have been set before your operation ran.
icke	hmm? it isn't $!
PerlJam	spectre^: you need to check for -1 to see if it failed to execute, and check $? & 127 to see if it died, and if neither of those things are true, then you can use $?>>8 to find the exit value.
spectre^	As I was saying ... I can work with the return being 255 if that's what's supposed to be happening, but I dont understand why and I dont want to proceed until I do
spectre^	print ("Invalid begin date specified: " . $options{'b'});
icke	it's supposed to always contain the exit value (as described)
spectre^	I see that printed
spectre^	er
go|dfish	eval [ 1 - 1.2, 15 - 15.2 ]
spectre^	$? reports the exit status from the last system() command
spectre^	http://perldoc.perl.org/perlvar.html#$CHILD_ERROR
buubot	go|dfish: ["-0.2","-0.199999999999999"]
spectre^	PerlJam: I'll check
go|dfish	why does that return 2 different results ^^ ?
PerlJam	go|dfish: floating point representation error.
DrForr	go|dfish: Because 1/5 can't be exactly represented in binary. In the first case you just get lucky.
PerlJam	go|dfish: either use fixed point (if you can) or always be sure to specify the precision of your floating point numbers on output
PerlJam	go|dfish: (unless you want more precision than the floating point error, you'll be fine)
spectre^	http://pastebin.com/m27595d
buubot	spectre^:  The 25 line paste m27595d has been copied to http://erxz.com/pb/22640  .
spectre^	Still getting a 255
go|dfish	PerlJam: ah
spectre^	With those checks in
go|dfish	DrForr, PerlJam, thanks!
spectre^	And neither of the if statements were true
PerlJam	spectre^: you always see "NOTICE gcum returned 255" just before it dies?
PerlJam	er, s/gcum/gsum/ even
PerlJam	(*NOT* a freudian slip  :)
spectre^	Yes, sir
spectre^	I do
spectre^	WAIT
LeoNerd	A freudian slip is when you say one thing but mean your mother
spectre^	Let me make sure tehre's not an END defined
spectre^	In the callee
spectre^	That changes my exit status
spectre^	Nope
spectre^	That's not it
PerlJam	spectre^: have you tried changing "exit(1)" to "exit(42)" or something?
spectre^	I'll try it
icke	spectre^: take the literal code from perldoc -f system to interpret $?. works for me
spectre^	I see what's wrong
PerlJam	It's that exit(255) that you forgot about?
PerlJam	:)
spectre^	Someone else is working on the callee and installed their version of it to /usr/local
spectre^	Fucker
spectre^	His version uses die()
spectre^	No
spectre^	:)
spectre^	die() returns 255
spectre^	And his version uses die()
spectre^	When I changed it to exit(69) and there was no effect I knew something was wrong :P
spectre^	Awesome thanks for the help
spectre^	Now I need help beating that guy down

shadowpaste0	"paull" at 119.10.140.36 pasted "Help! Why this snippet is not working, @_ is a count of traffic in octets passed in. It's bitching about $custtraffic not being defined and returns 0" (20 lines) at http://scsys.co.uk:8002/37956
paull	Thanks in advance for any help with my above paste
DrForr	paull: Maybe you're not aware that @_ is a list, not a variable.
paull	I'm only squirting in one value... Would I use $_ instead then?
Khisanth	Number::Bytes::Human
Khisanth	@_ < 1000000000 compares the number of args passed in
Khisanth	if you passed in only one value then @_ == 1
DrForr	sub FormatTraffic { my $count = shift; ... }
paull	Ahhh OK
paull	I'll give that a go.. Thanks so much!
paull	DrForr: happy to help further? Still returns 0!
DrForr	Well, kind of hard to tell what's going on without seeing sample input.
DrForr	And the rewritten version.
paull	OK
paull	I'll plug away at it

bennymack	anyone have experience embedding functions into SQLite? I have a list of zip codes in a csv file and I'd like to be able to get a list of other zipcodes in a N mile radius with one round-trip..
Khisanth	this is probably a very silly use of it :)
bennymack	I'm having a look at SQLite::VirtualTable now. Looks promising
bennymack	there's something like over 500 results for SQLite on CPAN thouhg
Khisanth	my $my_nick = '...'; my $me; @users = gather { for(@users) { if($_->{nick} eq $my_nick) { $me = $_ } else { take $_ } }
Khisanth	bennymack: do you need a virtual table or do you need a function? because DBD::SQLite has a sqlite_create_function method
bennymack	Khisanth: well, I thought the sqlite_create_function stuff happened on the DBI side of things?
waltman	bennymack: I've given a talk at a few yapcs on writing sqlite functions :)
bennymack	i've been to those talks ;)
waltman	yay!
waltman	my impression is that there's not really a "round trip", since you're making library calls
waltman	I think you can only return a scalar from a function, so I'm not sure how you could return a list.  Maybe as a comma-separated string?
bennymack	well, I need to fetch the zip in question, calculate a x and y min and max and select zips that fall within that range.
bennymack	I have code to do all that. but i'd prefer to just be able to send the zip and distance and get back a list of zip codes.
icke	that's an n-mile square, not radius
bennymack	icke: yes, thanks ;0
waltman	I don't see any way to have an sqlite function return more than one column, let alone multiple rows
waltman	I think the best you could do is return a string like "90210,90211,31459" and then have the caller split it
Thuryn	what?
Thuryn	waltman, are you new/
Thuryn	return() *always* returns a list
Thuryn	return('foo', 'bar', 'baz');
Thuryn	returning a single value is just a special case
awnstudio	un huh
