Hack 24. Find Recipes

Let the Google API transform those random
ingredients in your fridge into a wonderful dinner .

Google can help you find news, catalogs,
discussions, web pages, and so much moreand it can also help
you figure out what to have for dinner tonight!

This hack uses the Google API to help you transform those random
ingredients in your fridge into a wonderful dinner. Well, you do have
to do some of the work. But it all starts with this hack.

2.6.1. The Code

This hack comes with a built-in form that calls the query and the
recipe type, so there's no need to set up a separate
form:

#!/usr/local/bin/perl
# goocook.cgi
# Finding recipes with google.
# goocook.cgi is called as a CGI with form input.
# Your Google API developer's key
my $google_key='insert key here';
# Location of the GoogleSearch WSDL file.
my $google_wdsl = "./GoogleSearch.wsdl";
use SOAP::Lite;
use CGI qw/:standard/;
my %recipe_types = (
"General" => "site:allrecipes.com | site:cooking.com | site:
epicurious.com | site:recipesource.com",
"Vegetarian/Vegan" => "site:fatfree.com | inurl:veganmania | inurl:
vegetarianrecipe | inurl:veggiefiles",
"Wordwide Cuisine" => "site:Britannia.org | inurl:thegutsygourmet |
inurl:simpleinternet | inurl:soupsong"
);
print
header( ),
start_html("GooCook"),
h1("GooCook"),
start_form(-method=>'GET'),
'Ingredients: ', textfield(-name=>'ingredients'),
br( ),
'Recipe Type: ', popup_menu(-name=>'recipe_type',
-values=>[keys %recipe_types], -default=>'General'),
br( ),
submit(-name=>'submit', -value=>"Get Cookin'!"),
submit(-name=>'reset', -value=>"Start Over"),
end_form( ), p( );
if (param('ingredients')) {
my $google_search = SOAP::Lite->service("file:$google_wdsl");
my $results = $google_search ->
doGoogleSearch(
$google_key,
param('ingredients') . " " . $recipe_types{param('recipe_type')},
0, 10, "false", ", "false", ", "latin1", "latin1"
);
@{$results->{'resultElements'}} or print "None";
foreach (@{$results->{'resultElements'}}) {
print p(
b($_->{title}||'no title'), br( ),
a({href= br( ),
i($_->{snippet}||'no snippet')
);
}
}
print end_html( );

Save the code as a CGI script ["How to Run the
Scripts" in the Preface] named
goocook.cgi in your web site's
cgi-bin directory.

2.6.2. Running the Hack

This hack runs as a CGI script, producing a dynamic web page
alongside the rest of the pages in your web site. Since just where
you place and how you run CGI scripts varies from server to server
and ISP to ISP, you're best left to ask your
administrator or provider for help.

Once the script is in place, call it by pointing your Web browser at
goocook.cgi, fill in the ingredients you have on
hand, select a recipe type, and hit the "Get
Cookin'!" button.

2.6.3. Hacking the Hack

Of course, the most obvious way to hack this hack is to add new
recipe options to it. That involves first finding new recipe sites,
and then adding them to the hack.

Adding new recipe sites entails finding the domains that you want to
search. Use the cooking section of the Google Directory to find
recipes, starting here: http://directory.google.com/Top/Home/Cooking/Recipe_Collections/.

Next, find what you want and build it into a query supplement like
the one in the form, surrounded by parentheses with each item
separated by a |. Remember, using the site: syntax
means that you'll be searching for an entire domain,
so if you find a great recipe site at http://www.geocities.com/reallygreat/food/recipes/,
don't use the site: syntax to
search it; use the inurl: search instead
(inurl:geocities.com/reallygreat/food/recipes).
Just remember that an addition like this counts heavily against your
10-word query limit.

Let's look at an example. The cookbook section of
the Google Directory has a seafood section with several sites.
Let's pull out five sites and turn them into a
constraint on our query:

(site:simplyseafood.com | site:baycooking.com | site:coastangler.com | site:
welovefish.com | site:sea-ex.com) Next, test the query constraints live in Google by adding a query (in
this case, salmon) and running it as a search:

salmon (site:simplyseafood.com | site:baycooking.com | site:coastangler.com
| site:welovefish.com | site:sea-ex.com) Run a few different queries with a few different query words
(salmon, scallops, whatever)
and make sure that you're getting a decent number of
results. Once you're confident that you have a good
selection of recipes, you'll need to add this new
option to the hack:

my %recipe_types = (
"General" => "site:allrecipes.com | site:cooking.com | site:
epicurious.com | site:recipesource.com",
"Vegetarian/Vegan" => "site:fatfree.com | inurl:veganmania | inurl:
vegetarianrecipe | inurl:veggiefiles",
"Wordwide Cuisine" => "site:Britannia.org | inurl:thegutsygourmet |
inurl:simpleinternet | inurl:soupsong"
);

Simply add the name you want to call the option (a
=>) and the search string. Make sure you add it
before the closing parenthesis and semicolon. Your code should look
something like the code shown next.

my %recipe_types = (
"General" => "site:allrecipes.com | site:cooking.com | site:
epicurious.com | site:recipesource.com",
"Vegetarian/Vegan" => "site:fatfree.com | inurl:veganmania | inurl:
vegetarianrecipe | inurl:veggiefiles",
"Wordwide Cuisine" => "site:Britannia.org | inurl:thegutsygourmet |
inurl:simpleinternet | inurl:soupsong"
" Seafood" => "site:simplyseafood.com | site:baycooking.com | site :

coastangler.com | site:welovefish.com | site:sea-ex.com "
);

You can add as many search sets to the hack as you want. You may want
to add Chinese Cooking, Desserts, Soups, Salads, or any number of
other options. Tara Calishain and Judy Hourihan
