If the value is
base-char
then:
(make-string 3)
returns a
simple-base-string
. If the value is
lw:simple-char
then the same form returns a
lw:simple-text-string
.
If the value of
lw:*default-character-element-type*
is
base-char
, then
(coerce
sequence
'simple-string)
attempts to construct a
simple-base-string
. This will signal an error if any element of
sequence
is not a
base-char
.
If the value of
lw:*default-character-element-type*
is
simple-char
, then
(coerce
sequence
'simple-string)
attempts to construct a
simple-text-string
. This will signal an error if any element of
sequence
is not a
simple-char
.
Other string constructors also take their default from
lw:*default-character-element-type*
. For instance, the string reader will always construct a string of type determined by this variable, unless it sees a character of a larger type, in which case a suitable string is constructed. Also
with-output-to-string
and
make-string-output-stream
will construct a stream with element type determined by this variable and generate a string of the same element type.
