;; The distinction is that re-find tries to find _any part_ of the string ;; that matches the pattern, but re-matches only matches if the _entire_ ;; string matches the pattern. (re-matches #"hello" "hello, world") nil (re-matches #"hello.*" "hello, world") "hello, world" (re-matches #"hello, (.*)" "hello, world") ["hello, world" "world"]

; Regex match flags can be embedded in the regex string. So, we can convert the normal case-sensitive matching into case-insensitive matching. (re-matches #"hello" "HELLO") ; case-sensitive nil (re-matches #"(?i)hello" "hello") ; case-insensitive "hello" (re-matches #"(?i)hello" "HELLO") ; case-insensitive "HELLO" (re-matches #"(?i)HELLO" "heLLo") ; case-insensitive "heLLo"
