package
.
nil
if no such package exists or is known.
See the function symbol-package.
find-package
consult this mapping in order
to find a package from its name.
Operators such as do-all-symbols
, find-all-symbols
,
and list-all-packages
operate only on packages that exist
in the package registry.
psetq
, let
, or do
;
that is, first evaluating all of the forms that produce values,
and only then assigning or binding the variables (or places).
Note that this does not imply traditional computational “parallelism”
since the forms that produce values are evaluated sequentially.
See sequential.
"~3,'0D"
, the number 3
and the character
#\0
are parameters to the ~D
format directive.”
(eql
object)
.
(eql
form)
.
pathname
, which is a structured representation
of the name of a file. A pathname has six components:
a “host,”
a “device,”
a “directory,”
a “name,”
a “type,” and
a “version.”
*print-pprint-dispatch*
and hence can control how objects are printed when
*print-pretty*
is true.
See Section 22.2.1.4 (Pretty Print Dispatch Tables).
*print-pretty*
is true,
and that uses layout techniques (e.g., indentation) that
tend to highlight the structure of the object in a way that
makes it easier for human readers to parse visually.
See the variable *print-pprint-dispatch* and Section 22.2 (The Lisp Pretty Printer).
pprint-logical-block
as a link between the output stream
and the logical block.
nil
if there are no values.
“The primary value returned by truncate
is an
integer quotient, truncated toward zero.”
*print-escape*
and *print-readably*
.
If the value of either *print-readably*
or *print-escape*
is true,
then printer escaping is “enabled”;
otherwise (if the values of both *print-readably*
and *print-escape*
are false),
then printer escaping is “disabled”.
