# Perl has shitty stuff
|
|
|
|
Perl functions fucking sucks
|
|

|
|
sub pile_of_crap
|
|
{
|
|
my $x = shift; # $x is 3 if pile\_of\_crap(3)
|
|
# do something with $x
|
|
}
|
|
~~~
|
|
Why can't it be normal?

sub pile_of_crap(my $x)

# do shit with $x;

### $ @ % &
|
|
|
|
Those symbols (altough they aren't confusing) are useless: for example
|
|
|
|
remember this:
|
|
|
|
* $: Scalars, numbers or strings (or references)
|
|
* @: Arrays
|
|
* %: Hashes, associative arrays
|
|
|
|
~~~
|
|
my @array = qw(hello this is an array);
|
|
|
|
# How would you print the first element? print @array[0]? haha!
|
|
|
|
print $array[0]; # prints hello
|
|
~~~
|
|
|
|
That's right! you converted from an array to a scalar (it makes sense
|
|
though, but it's VERY confusing)
|
|
|
|
same thing with hashes:
|
|
|
|
~~~
|
|
my %hash = qw(qorg asshole lain cute_hacker);
|
|
|
|
print $hash{qorg} # prints asshole
|
|
~~~
|
|
|
|
Again, that's right! you converted a motherfucking associative array
|
|
into a fucking scalar (again, makes a lot of sense when you think
|
|
about it, you're getting only a string, but it can be VERY confusing)
|
|
|
|
### There is more than one way to do it
|
|
|
|
And that's based tbh
|
|
|
|
Before, i defined an array and a hash using qw, because its a lot
|
|
easier than do this:
|
|
|
|
~~~
|
|
my @array = ('hello','this','is','an','array');
|
|
~~~
|
|
|
|
That's the most common way to define an array. But you can also
|
|
fucking do:
|
|
|
|
~~~
|
|
my @array;
|
|
$array[0] = "hello";
|
|
$array[1] = "this";
|
|
$array[2] = "is";
|
|
$array[3] = "an";
|
|
$array[4] = "array";
|
|
$array[1312312312] = "wtf"; # from 5 to 1312312312, contents are NULL.
|
|
~~~
|
|
|
|
### use strict
|
|
|
|
really? it should be enabled by default. it shold be ```use
|
|
unstrict``` instead
|

visiting code you wrote some weeks ago will make you cry.

# But it is, still, the greatest programming language the world has ever known.
