Bounding index designators of string1
Bounding index designators of string2
A keyword
The functions
unicode-string-greaterp
and
unicode-string-lessp
compare the designated substrings of
string1
and
string2
, similarly to
cl:string-greaterp
and
cl:string-greaterp
but ignoring case using Unicode rules specified by
style
. The values of
start1
and
start2
default to 0, while the values of
end1
and
end2
default to
nil
.
The value of
mismatch-index
is the index where the strings mismatch (as an offset from the beginning of
string1
) if
substring1
is greater (or for
unicode-string-lessp
, less) than
substring2
, or
nil
otherwise.
The current implementation only supports one style of comparison:
Compares each character of the string using Unicode's simple lowercase folding rules.
