Hello,
Carl: I know about that section but i do not know how to make any thing there work for this Do you have an example? Thank you,ƒghttps://www.gnu.org/software/guile/manual/html_node/List_002fString-Conversion.html Carl
This is:
(string->list "abcd")
returning (#\a #\b #\c #\d).
This procedure converts a string into a list of
characters.
You may want a list of single-character strings instead.
Then here you go:
(map string (string->list "abcd"))
Thas gives ("a" "b" "c" "d").
The other one on the same page is for splitting a string
following certain criteria. For example, if you want to split
by spaces, then that would be
(string-split "Hello world!" #\space)
resulting in ("Hello" "world!").
And, if you want symbols,
(map string->symbol (map string (string->list "-3 31 A -6 B -8")))
That said, I don't really understand why you are mixing
numbers and letters in your strings. As David suggested,
it would be more natural to start with a list. And if
you provide context about what you're trying to achieve,
we likely can give more helpful answers.
Best,
