Node:SRFI-13 Predicates, Next:SRFI-13 Constructors, Previous:Loading SRFI-13, Up:SRFI-13
In addition to the primitives string?
and string-null?
,
which are already in the Guile core, the string predicates
string-any
and string-every
are defined by SRFI-13.
string-any pred s [start end] | Scheme Procedure |
Check if the predicate pred is true for any character in
the string s, proceeding from left (index start) to
right (index end). If string-any returns true,
the returned true value is the one produced by the first
successful application of pred.
|
string-every pred s [start end] | Scheme Procedure |
Check if the predicate pred is true for every character
in the string s, proceeding from left (index start)
to right (index end). If string-every returns
true, the returned true value is the one produced by the final
application of pred to the last character of s.
