如何在多个条件下拆分？

Question

使用Ruby，我如何在两种情况下分开 - 有3个或更多空格还是标签字符？我试过这个

2.4.0 :003 > line = "a\tb\tc"
 => "a\tb\tc"
2.4.0 :004 > line.split(/([[:space:]][[:space:]][[:space:]]+|\t)/)
 => ["a", "\t", "b", "\t", "c"]

但正如您所看到的，标签字符本身已包含在我的结果中。结果应该是

["a", "b", "c"]

Answer 1

仅split怎么样？

p "a\tb\tc".split
# ["a", "b", "c"]
p "a\tb\tc\t\tc\t\t\t\t\t\t\tc\ts\ts\tt".split
# ["a", "b", "c", "c", "c", "s", "s", "t"]

虽然当有三个或更多三个空格时，它不会分裂，但这可能会有效：

p "a\tb\tc\t\tc\t\t\   t\t\tc\ts\ts\tt".split(/\s{3,}|\t/)
# => ["a", "b", "c", "c", "t", "c", "s", "s", "t"]

Answer 2

line = "aa bb    cc\tdd"
line.split /\p{Space}{3,}|\t+/
#⇒ ["aa bb", "cc", "dd"]
