正则表达式。

# => ["a", "b", "c", "d"]

word.scan(/\w+/)
# => ["Now", "is", "the", "time", "for", "all", "good", "people"]

You can use a combination of the splitmethod and the Regexp.unionmethod like so:
您可以像这样使用split方法和Regexp.union方法的组合：
delimiters = [',', ' ', "'"]
word.split(Regexp.union(delimiters))
# => ["Now", "is", "the", "time", "for", "all", "good", "people"]
You can even use regex patters in the delimiters.
您甚至可以在分隔符中使用正则表达式模式。
delimiters = [',', /\s/, "'"]
word.split(Regexp.union(delimiters))
# => ["Now", "is", "the", "time", "for", "all", "good", "people"]
This solution has the advantage of allowing totally dynamic delimiters or any length.
该解决方案的优点是允许完全动态的定界符或任何长度。
