39.11.4 List/String Conversion

The procedure string->list is extended by SRFI-13, that is why it is included in (srfi srfi-13). The other procedures are new. The Guile core already contains the procedure list->string for converting a list of characters into a string (see List/String Conversion).

— Scheme Procedure: string->list str [start [end]]

Convert the string str into a list of characters.

— Scheme Procedure: reverse-list->string chrs

An efficient implementation of (compose string->list reverse):

          (reverse-list->string '(#\a #\B #\c)) ⇒ "cBa"
— Scheme Procedure: string-join ls [delimiter [grammar]]

Append the string in the string list ls, using the string delim as a delimiter between the elements of ls. grammar is a symbol which specifies how the delimiter is placed between the strings, and defaults to the symbol infix.

infix
Insert the separator between list elements. An empty string will produce an empty list.
string-infix
Like infix, but will raise an error if given the empty list.
suffix
Insert the separator after every list element.
prefix
Insert the separator before each list element.
