ANSI Common Lisp  10 Symbols 10.2 Dictionary of Symbols
| 10.2.5 make-symbol |
Function |
- Syntax:
-
make-symbol
name
 new-symbol
- Arguments and Values:
-
name - a string.
new-symbol - a fresh, uninterned symbol.
- Description:
-
make-symbol creates and returns a fresh, uninterned
symbol whose name is the given name.
The new-symbol is neither bound nor fbound
and has a null property list.
It is implementation-dependent whether the string
that becomes the new-symbol's name is the given
name or a copy of it. Once a string
has been given as the name argument to
make-symbol, the consequences are undefined if a
subsequent attempt is made to alter that string.
- Examples:
-
(setq temp-string "temp") "temp"
(setq temp-symbol (make-symbol temp-string)) #:|temp|
(symbol-name temp-symbol) "temp"
(eq (symbol-name temp-symbol) temp-string) implementation-dependent
(find-symbol "temp") NIL, NIL
(eq (make-symbol temp-string) (make-symbol temp-string)) false
- Exceptional Situations:
-
Should signal an error of type type-error if name is not a string.
- See Also:
-
copy-symbol
- Notes:
-
No attempt is made by make-symbol to convert the case
of the name to uppercase. The only case conversion which ever
occurs for symbols is done by the Lisp reader.
The program interface to symbol creation retains case,
and the program interface to interning symbols is case-sensitive.
- Allegro CL Implementation Details:
-
None.
