DO-EXTERNAL-SYMBOLS | Macro |
Package:LISP
Syntax: (do-external-symbols (var [package [result-form]]) {decl}* {tag | statement}*) Executes STATEMENTs once for each external symbol in the PACKAGE (which defaults to the current package), with VAR bound to the current symbol. Then evaluates RESULT-FORM (which defaults to NIL) and returns the value(s). |
DO* | Special Form |
Package:LISP
Syntax: (do* ({(var [init [step]])}*) (endtest {result}*) {decl}* {tag | statement}*) Just like DO, but performs variable bindings and assignments in serial, just like LET* and SETQ do. |
DO-ALL-SYMBOLS | Macro |
Package:LISP
Syntax: (do-all-symbols (var [result-form]) {decl}* {tag | statement}*) Executes STATEMENTs once for each symbol in each package, with VAR bound to the current symbol. Then evaluates RESULT-FORM (which defaults to NIL) and returns the value(s). |
YES-OR-NO-P (&optional (format-string nil) &rest args) | Function |
Package:LISP
Asks the user a question whose answer is either 'YES' or 'NO'. If FORMAT- STRING is non-NIL, then FRESH-LINE operation is performed, a message is printed as if FORMAT-STRING and ARGs were given to FORMAT, and then a prompt "(Yes or No)" is printed. Otherwise, no prompt will appear. |
MAPHASH #'hash-table | Function |
Package:LISP
For each entry in HASH-TABLE, calls FUNCTION on the key and value of the entry; returns NIL. |
MAPCAR (fun list &rest more-lists) | Function |
Package:LISP
Applies FUN to successive cars of LISTs and returns the results as a list. |
DOLIST | Special Form |
Package:LISP
Syntax: (dolist (var listform [result]) {decl}* {tag | statement}*) Executes STATEMENTs, with VAR bound to each member of the list value of LISTFORM. Then returns the value(s) of RESULT (which defaults to NIL). |
EQ (x y) | Function |
Package:LISP
Returns T if X and Y are the same identical object; NIL otherwise. |
EQUALP (x y) | Function |
Package:LISP
Returns T if X and Y are EQUAL, if they are characters and satisfy CHAR-EQUAL, if they are numbers and have the same numerical value, or if they have components that are all EQUALP. Returns NIL otherwise. |
EQUAL (x y) | Function |
Package:LISP
Returns T if X and Y are EQL or if they are of the same type and corresponding components are EQUAL. Returns NIL otherwise. Strings and bit-vectors are EQUAL if they are the same length and have identical components. Other arrays must be EQ to be EQUAL. |
DO-SYMBOLS | Macro |
Package:LISP
Syntax: (do-symbols (var [package [result-form]]) {decl}* {tag | statement}*) Executes STATEMENTs once for each symbol in the PACKAGE (which defaults to the current package), with VAR bound to the current symbol. Then evaluates RESULT-FORM (which defaults to NIL) and returns the value(s). |
LOOP | Special Form |
Package:LISP
Syntax: (loop {form}*) Executes FORMs repeatedly until exited by a THROW or RETURN. The FORMs are surrounded by an implicit NIL block. |
