我发现自己经常使用这种模式，我想知道内置库中是否有某些东西可以在不添加所有这些控制流语句的情况下执行此操作。我所拥有的是：
input = <<TEXT
/us/programming/sports:model.channel.tnt.name
/us/programming/sports:model.channel.spice.name
/us/programming/sports:model.classificationwebgenre.us-entertainment.programming_link_text
/international-sports/package:model.language.international-sports.name
/brazilian/programming/sports:model.package.hbo-extra.description
TEXT
def self.create_hash(text)
output = {}
text.each_line("\n") do |line|
split_lines = line.split(":")
if output.has_key?(split_lines.first)
output[split_lines.first] << split_lines[1][0..-2]
else
output[split_lines.first] = [split_lines[1][0..-2]]
end
end
output
end
结尾
也是这样的输出：
{
"/us/programming/sports" => ["model.channel.tnt.name", "model.channel.spice.name", "model.classificationwebgenre.us-entertainment.programming_link_text"],
"/international-sports/package" => ["model.language.international-sports.name"],
"/brazilian/programming/sports" => ["model.package.hbo-extra.description"]
}
我只是在用这种方式使事情变得过于复杂吗？有没有惯用的方法用红宝石来写这个？提前致谢。
不确定是否更快，但是更干净
def self.create_hash(text)
output = {}
text.each_line("\n") do |line|
split_lines = line.split(":")
output[split_lines.first] ||= []
output[split_lines.first] << split_lines[1][0..-2]
end
output
end
