(bldmsg FORMAT:string, [ARGS:any]): string expr
Printf to string. This can be used as a very convenient way of obtaining the
printed representation of an object for further analysis. In many cases it is
also a very convenient way of constructing a needed string. An error will
occur on overflow. Overflow occurs when the length of the result exceeds
the value of maxtokensize.
(flatsize U:any): integer expr
Character length of prin1 S-expression.
(flatsize2 U:any): integer expr
Prin2 version of flatsize.
(explode U:any): id-list expr
Explode takes the constituent characters of an S-expression and forms a
list of single character ids. It is implemented via the function channelprin1,
with a list rather than a file or terminal as destination. Returned is a list of
interned characters representing the characters required to print the value of
U.
(explode2 U:atom-vector): id-list expr
Prin2 version of explode.
(compress U:id-list): atom-vector expr
U is a list of single character identifiers which is built into a PSL entity and
returned. Recognized are numbers, strings, and identifiers with the escape
character prefixing special characters. The formats of these items appear
in the ”Primitive Data Types” Section, Section 2.1.2. Identifiers are not
interned on the id-hash-table. Function pointers may not be compressed. If
an entity cannot be parsed out of U or characters are left over after parsing
an error occurs:
(implode U:id-list): atom expr
Compress with ids interned.
