Garbage generator

When your teacher asks you to write a script that randomly mixes grammatical parts of a sentence because you didn’t did your homework is what causes this kind of post.

Actually there were more restrictions. I had to do it in less than 10 minutes, the resulting sentence needed to be understandable despite the possible genre errors and finally, the sentence should be generated in Spanish.

The script is made in Perl. It was easy to build and luckily took me less than 10 minutes to entirely write both the code and the feeders (the files with the words to build the sentence).


use warnings;
use strict;

sub main()
my @articles = open_file($ARGV[0]);
my @subjects = open_file($ARGV[1]);
my @verbs = open_file($ARGV[2]);
my @complements = open_file($ARGV[3]);

my %rules = ( ‘a’ => @articles,
‘s’ => @subjects,
‘v’ => @verbs,
‘c’ => @complements);

my @expr = split(/+/, $ARGV[4]);

for my $token ( @expr )
my $index = int(rand(scalar(@{$rules{$token}})));

my $word = @{$rules{$token}}[$index];
$word =~ s/n+/ /g;
print $word;

print “n”;


sub open_file($)
my $file = shift;

open(FILE, “< $file") || die "Error: $!n"; return ;


The program receives 5 parameters from command line: the articles file, the subjects file, the verbs file, the complements file and the expression which determines how to build the sentences combining the words.


$ perl articles subjects verbs complements “a+s+v+c”


The above call produces mostly nonsense and funny sentences like:

– el edificio duerme todo al pedo
– un alumno estudia como la mierda
– la puerta rie
– las perro habla todo al pedo
– una profesor come cualquier cosa

It was a funny thing to do. I don’t know if the script worth a post in my blog but here it is and I laughed a lot 😀
