Using lc within declaration 2

[1DMF]

Hello peeps,

Like usual i'm trying to cut corners and define a whole load of stuff on one line, only I get the following error...

Can't declare lc in "my"

So is there a way to use the following code correctly?
without using 2 lines of code - i know but hey i'm bored and thought I'd ask!

my ($fn,lc($ext)) = split(/./, $img);

Can't declare lc in "my"

I think perl thinks that you think that you want to redefine the lowercase function, hence borkage ;-)

--Paul

my ($fn,$ext);
($fn,lc($ext)) = split(/./, $img);

should work

but that's using 2 lines of code so doesn't meet my criteria and there was a typo in the code, forgot to escape the period!

my($fn,$ext) = split(/[b]\[/b]./, $img);

I know, this was just one of those stupid questions , when i got an error tying to be smart! I ended up going for

my ($fn,$ext) = split(/\./, $img);
lc($ext);

Your use of lc there won't do anything. It doesn't affect the variable passed to it, just returns a lowercased version of it, so you have to assign it somewhere:

$ext = lc $ext;

doh - but i'm suprised ishnid, a man of your calibre not able to give me the 1 liner I wanted

About as contrived a one-liner I can think of:

my ( $fn, $ext ) = map /\./ ? substr( $_, 0, -1 ) : lc, split /(?<=\.)/, $img;

Seriously, though. Do it in two lines ;-)

I knew you had it in you

and you're right like hell am I using that, talk about making your PERL code difficult to read!
