21.4.4 List/String conversion

When processing strings, it is often convenient to first convert them into a list representation by using the procedure string->list, work with the resulting list, and then convert it back into a string. These procedures are useful for similar tasks.

string->list str Scheme Procedure
scm_string_to_list (str) C Function
Return a newly allocated list of the characters that make up the given string str. string->list and list->string are inverses as far as equal? is concerned.

string-split str chr Scheme Procedure
scm_string_split (str, chr) C Function
Split the string str into the a list of the substrings delimited by appearances of the character chr. Note that an empty substring between separator characters will result in an empty string in the result list.
(string-split "root:x:0:0:root:/root:/bin/bash" #\:)
("root" "x" "0" "0" "root" "/root" "/bin/bash")

(string-split "::" #\:)
("" "" "")

(string-split "" #\:)
