I feel there must be a way to do this... given func( foo => 1, bar => 2 ); how to write my ( $foo, $bar ) = .... inside the function? |
| LeoNerd |
My current attempt is my ( $foo, $bar ) = @{{@_}}{qw( foo bar )}; which is messy as sin |
| icke |
LeoNerd: what's the problem? readability? |
| LeoNerd |
Yah |
| dazjorz |
LeoNerd: I'd change specs to be func({ foo => 1, bar => 2}) |
| dazjorz |
then my ($foo, $bar) = ($_[0]{foo}, $_[0]{bar}); |

Leonerd: If you insist on doing it on one line, that's about as good as it gets. But why not use a temporary hash ? Should be just as fast and as readable |
| LeoNerd |
Hrm.. :/ Then it's only marginally nicer as my ( $foo, $bar ) = @{$_[0]}{qw( foo bar )}; |
| LeoNerd |
my %args = @_; my ( $foo, $bar ) = @args{qw( foo bar )}; ya... that works |
| mst |
LeoNerd: my ($foo, $bar) = do { my %a = @_; @a{qw(foo bar)} }; |
| ton |
if you combine it with a delete you can then check if %args is empty and catch typos or unexpected arguments.... |
| LeoNerd |
Oooh.. a do block |
| vincent |
or use padwalker |
| LeoNerd |
Oh, args won't be empty... this is a wrapper function that pulls a few named args off and sends the rest to a nested inner function |
| LeoNerd |
Now.. I want to call a function "foreach" but that breaks things... suggestions? |
| icke |
a method could be named 'foreach' |
| LeoNerd |
Ya.. but this is a plain function |
| icke |
tough |
| LeoNerd |
I suppose "iterate" is about as best as I'll get |
| icke |
for_each |
| ton |
LeoNerd: forall ? |
| LeoNerd |
I'll think on it overnight maybe.. I guess it's home time now |

forevery? |
| rindolf |
<LeoNerd> one_for $all and $all for @one; - heh |
| rindolf |
$one for @all and @all for @one |
| rindolf |
$one for @all and @all for @$one |
| rindolf |
$one for @all and @all for $one |
| rindolf |
Works too. |
| LeoNerd |
Hrm.. it does? |
| LeoNerd |
deparse: $one for @all and @all for $one |
| buubot |
LeoNerd: Error: syntax error at (eval 107195) line 1, near "@all for " |

You can't use two postmod fors in a single statement |
