Clojure：我可以用什么正则表达式来检测多行字符串中一行的最后一个字符？

Question

I am trying to match the last character at the end of each line (multi-line text string) in Clojure. Here is a sample text:

"Possible values:

copy: A copy of the source item is made at the new location.
move: An item is moved to a new location.
link: A link is established to the source at the new location.
none: The item may not be dropped."

I tried #"\\n" but that only matches a new line.

Answer 1

Use #"\\n|$" ; \\n to match all newlines except the last one, and $ to match the last one.

user=> (print (clojure.string/replace text #"\n|$" "...\n"))
Possible values:...
...
copy: A copy of the source item is made at the new location....
move: An item is moved to a new location....
link: A link is established to the source at the new location....
none: The item may not be dropped....
