建议你看看rmxp里的Regexp类与正则表达式（不保证你能看懂）
字符串的split方法的用途是把字符串对象按该方 ...

description的值变成@skill.description里的第0个“乱七八糟”后面的字符串？
比如@skill.description是“1 ...

#split(pattern = $;, [limit]) ⇒ Array

Divides str into substrings based on a delimiter, returning an array of these substrings.

If pattern is a String, then its contents are used as the delimiter when splitting str. If pattern is a single space, str is split on whitespace, with leading whitespace and runs of contiguous whitespace characters ignored.

If pattern is a Regexp, str is divided where the pattern matches. Whenever the pattern matches a zero-length string, str is split into individual characters.

If pattern is omitted, the value of $; is used. If $; is nil (which is the default), str is split on whitespace as if ` ' were specified.

If the limit parameter is omitted, trailing null fields are suppressed. If limit is a positive number, at most that number of fields will be returned (if limit is 1, the entire string is returned as the only entry in an array). If negative, there is no limit to the number of fields returned, and trailing null fields are not suppressed.

" now's  the time".split       #=> ["now's", "the", "time"]
" now's  the time".split(' ') #=> ["now's", "the", "time"]
" now's  the time".split(/ /) #=> ["", "now's", "", "the", "time"]
"1, 2.34,56, 7".split(%r{,\s*}) #=> ["1", "2.34", "56", "7"]
"hello".split(//)             #=> ["h", "e", "l", "l", "o"]
"hello".split(//, 3)          #=> ["h", "e", "llo"]
"hi mom".split(%r{\s*})       #=> ["h", "i", "m", "o", "m"]

"mellow yellow".split("ello") #=> ["m", "w y", "w"]
"1,2,,3,4,,".split(',')       #=> ["1", "2", "", "3", "4"]
"1,2,,3,4,,".split(',', 4)    #=> ["1", "2", "", "3,4,,"]
"1,2,,3,4,,".split(',', -4)    #=> ["1", "2", "", "3", "4", "", ""]

RMXP中并没有String#split的说明，因此RMXP的帮助有很多不全面的地方，毕竟这不是Ruby的API手册。
