How could I split commas excepts it's in double quotes

s1 ='a,b,c,"x,y,z" '
m1 = s1.split(',') 

"x,y,z" should not be splitted by comma

The expected result should be [‘a’,’b’,’c’,”x,y,z”], total size is 4

How could I do that in Ruby

    Use the csv module:

    irb(main):001:0> require 'csv'
    => true
    irb(main):002:0> CSV.parse_line('a,b,c,"x,y,z"')
    => ["a", "b", "c", "x,y,z"]

    Try this:

    s1 ='a,b,c,"x,y,z" '
    quotes = s1.match(/".+"/)

    Could it be? Is it possible? Do I finally have a chance to use Ruby’s bordering-on-bizarre flip-flop operator?

    Let’s try:

    str ='a,b,c,"x,y,z",d,e,"1,2,3",f '
    u = ''  
    str.split(?,).each_with_object([]) do |s,a|
      t = s.strip
      if (t[0]==?") .. (t[-1]==?")
        u = '' if t[0]==?"
        u << t
        if t[-1]==?"
          a << u
          u << ?,
        a << t
      #=> ["a", "b", "c", "\"x,y,z\"", "d", "e", "\"1,2,3\"", "f"]
