將字符串轉換爲元組，哈希或數組

Question

我有一個字符串：

"(\"Doe, John\",12345)" 

我想這個字符串轉換成一個元組("Doe, John",12345)，散列{"Doe, John" => 12345}或數組["Doe, John",12345]。

我不知道如何將它分成兩個元素"Doe, John"和12345。我想避免使用regex。我不能使用split，因爲我得到["(\"Doe", "John", "12345)"]。

Answer 1

Hash[*s[1..-2].gsub('"', '').reverse.sub(',', '|').reverse.split('|')] 

結果

{"Doe, John"=>"12345"} 

解釋：

s         # (\"Doe, John\",12345) 
s[1..-2]       # remove bracket => \"Doe, John\",12345 
.gsub('"', '')     # remove double quote => Doe, John,12345 
.reverse.sub(',', '|').reverse # make the last , into | => Doe, John|12345 
.split('|')      # split the string to array => ["Doe, John", "12345"] 
Hash[*s]       # make the array into hash => {"Doe, John"=>"12345"} 

Answer 2

你應該使用情況scan尚且如此，split。

"(\"Doe, John\",12345)"[1...-1] 
.scan(/(?<=")[^"]*(?=")|[^,"]+/) 
# => ["Doe, John", "12345"]
