In perl, what is the difference between $DB::single = 1 and 2? -

-

what difference between putting $db::single=1 , $db::single=2 in code? both seem have identical effect of halting execution @ statement following assignment when 'c' on perl debugger command line.

perldebug says value of 1 equivalent having pressed 's' next statement, , 2 same 'n', difference make how got statement?

from perldebug:

if set $db::single 2, it's equivalent having typed n command (which executes on subroutine calls), whereas value of 1 means s command (which enters subroutine calls).

that know already.

from user point of view, i'm pretty sure there no difference. base on examination of actual db.pm source code.

let's follow logically. may want refer source code. i've simplified of code remove unnecessary detail should able idea descriptions.

when executing code in debugger, there (at least) 2 important variables, running , single. combination of these decides whether code run:

running  single  description -------  ------  -----------    0       ?     not running    1       0     running flat-out    1       1     single stepping, execute function    1       2     single stepping, execute on function

the db() function executed every single line, , contains following snippet stop running if single has been set (it executes current line regardless):

if ($db::single) {     $db::single = 0;     $running = 0; }

that's why, if set variable in perl code, break (by break, mean "stop running code", not "damage somehow") debugger @ next line.

when running 0, db() function enters little loop:

# sit in event loop until sets $running {     $c->idle;          # call client event loop; must not block } until $running;

in other words, waits on user command sets running 1. can done 1 of following 3 functions:

sub next {     $db::single = 2;     $running = 1; }  sub step {     $db::single = 1;     $running = 1; }  sub cont {     $db::single = 0;     $running = 1; }

you can see these 3 commands set different combination of single , running used while executing next perl line (see earlier table see these combinations mean).

the ability use either 1 or 2 in perl code direct result of fact you're using sneaky clever trick break execution perl code itself, setting variable set debugger command.

that's why it's not value matters fact you're forcing debugger particular state.

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
