PERL教程美食：用味道说话的代码337

PERL（Practical Extraction and Report Language，实用抽取和报告语言）是一种强大的脚本语言，因其灵活性和广泛的库而深受开发者们的喜爱。然而，您是否知道PERL也能用来制作美食呢？

PERL的美味优势

PERL为烹饪爱好者提供了许多优势，包括：* 自动化任务：使用PERL，您可以自动化重复性的烹饪任务，例如食谱转换、库存管理和计划菜单。
* 控制精度： PERL脚本可以精确地计算成分、转换单位，并根据喜好调整食谱。
* 灵活性： PERL代码非常灵活，可以适应不同的烹饪风格和口味偏好。
* 数据处理能力： PERL擅长处理大量数据，这使得它非常适合管理烹饪数据库和跟踪营养信息。

PERL美食库

有许多PERL库专门用于烹饪，包括：* Cookbook-Parser：用于从文本或HTML文件中解析食谱。
* Foodunit：用于转换烹饪单位。
* Recipe-Tools：用于创建、编辑和共享食谱。
* Winecellar：用于管理葡萄酒收藏。

美味的PERL食谱

以下是几个用PERL编写的美味食谱：

烤鸡
```perl
#!/usr/bin/perl
use Cookbook-Parser;
use Foodunit;
my $recipe = Cookbook-Parser->new->parse_file('');
my $chicken_weight = 3.5;
my $oven_temp = 375;
my $roasting_time = Foodunit::convert_time(30, 'minutes', 'hours');
print "Ingredients:";
print "\t1 whole chicken ($chicken_weight lbs)";
print "\t1 tablespoon olive oil";
print "\t1 teaspoon salt";
print "\t1 teaspoon pepper";
print "Instructions:";
print "\tPreheat oven to $oven_temp Fahrenheit.";
print "\tRinse chicken and pat dry.";
print "\tRub chicken with olive oil, salt, and pepper.";
print "\tRoast chicken for $roasting_time, or until cooked through.";
```

巧克力蛋糕
```perl
#!/usr/bin/perl
use Cookbook-Parser;
my $recipe = Cookbook-Parser->new->parse_file('');
my $flour = 2;
my $sugar = 2;
my $cocoa = 1;
my $butter = 1;
my $eggs = 2;
my $vanilla = 1;
print "Ingredients:";
print "\t$flour cups flour";
print "\t$sugar cups sugar";
print "\t$cocoa cups cocoa powder";
print "\t$butter cups butter, softened";
print "\t$eggs eggs";
print "\t$vanilla teaspoon vanilla extract";
print "Instructions:";
print "\tPreheat oven to 350 Fahrenheit.";
print "\tGrease and flour two 9-inch round cake pans.";
print "\tIn a bowl, combine flour, sugar, and cocoa.";
print "\tIn another bowl, cream together butter and vanilla.";
print "\tAdd eggs one at a time, beating well after each.";
print "\tGradually add dry ingredients to wet ingredients, mixing until just combined.";
print "\tPour batter into prepared pans and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.";
