29 ;; These are extensions to Emacs Lisp that provide a degree of | |
30 ;; Common Lisp compatibility, beyond what is already built-in | |
31 ;; in Emacs Lisp. | |
32 ;; | |
33 ;; This package was written by Dave Gillespie; it is a complete | |
34 ;; rewrite of Cesar Quiroz's original cl.el package of December 1986. | |
35 ;; | |
36 ;; Bug reports, comments, and suggestions are welcome! | |
37 | |
38 ;; This file contains the portions of the Common Lisp extensions | |
39 ;; package which should be autoloaded, but need only be present | |
40 ;; if the compiler or interpreter is used---this file is not | |
41 ;; necessary for executing compiled code. | |

256 `loop', which does a rather different way of destructuring. Anywhere | |
257 that a simple argument may appear, and (if following a lambda-list | |
258 keyword) a list may not normally appear, an embedded lambda list can be | |
259 substituted. (The format of the embedded lambda list is exactly the | |
260 same as for a top-level list except that &environment is not allowed.) | |
261 When matching this lambda list against a caller-specified argument, that | |
262 argument is treated as a list and normal lambda-list processing occurs, | |
263 just as if the entire operation were happening at top level. | |
264 Furthermore, any lambda list, embedded or top-level, can be dotted at its | |
265 end, and this will cause matching with an appropriate dotted list given | |
266 as an argument. | |
267 | |
268 See `loop' for practical examples of destructuring, but | |
269 keep in mind that `loop' destructuring is somewhat different from macro | |
270 destructuring in that | |
271 | |
272 (a) Macro destructuring has extra features in the various lambda-list | |
273 keywords, allowing for special processing of a list other than just | |
274 simple matching. | |
275 (b) Macro destructuring is strict, in that an error is signalled if the | |
276 actual structure does not match the expected structure. On the | |
277 other hand, loop destructuring is lax -- extra arguments in a list | |
278 are ignored, not enough arguments cause the remaining parameters to | |
279 receive a value of nil, etc. | |

872 | 554 "Bind the arguments in ARGS to EXPR then eval BODY. |
555 This is similar to `let' but it does \"destructuring\", in that it matches | |
556 the structure of ARGS to the structure of EXPR and binds corresponding | |
557 arguments in ARGS to their values in EXPR. The format of ARGS, and the | |
558 way the destructuring works, is exactly like the destructuring that occurs | |
559 in `defmacro*'; see that for more information. | |
560 | |
561 An alternative means of destructuring is using the `loop' macro. `loop' | |
562 gives practical examples of destructuring. `defmacro*' describes the | |
563 differences between loop and macro-style destructuring. | |
564 | |
565 You can rewrite a call to (destructuring-bind ARGS EXPR &rest BODY) using | |
566 `loop', approximately like this: | |
567 | |
568 (loop for ARGS = EXPR | |
569 return (progn BODY)) | |
570 | |
571 I say \"approximately\" because the destructuring works in a somewhat | |
572 different fashion, although for most reasonably simple constructs the | |
573 results will be the same." | |

786 "The Common Lisp `loop' macro. |
800 | 787 |
788 The loop macro consists of a series of clauses, which do things like | |
789 iterate variables, set conditions for exiting the loop, accumulating values | |
790 to be returned as the return value of the loop, and executing arbitrary | |
2297 | 791 blocks of code. Each clause is processed in turn, and the loop executes its |
800 | 792 body repeatedly until an exit condition is hit. |
793 | |
794 It's important to understand that loop clauses such as `for' and `while', | |
795 which look like loop-establishing constructs, don't actually *establish* a | |
796 loop\; the looping is established by the `loop' clause itself, which will | |
797 repeatedly process its body until told to stop. `while' merely establishes | |
798 a condition which, when true, causes the loop to finish, and `for' sets a | |
799 variable to different values on each iteration (e.g. successive elements of | |
800 a list) and sets an exit condition when there are no more values. This | |
801 means, for example, that if two `for' clauses appear, you don't get two | |
802 nested loops, but instead two variables that are stepped in parallel, and | |
803 two exit conditions, either of which, if triggered, will cause the loop to | |
804 end. Similarly for a loop with a `for' and a `while' clause. For example: | |
805 | |
806 \(loop | |
807 for x in list | |
808 while x | |
809 do ...) | |
810 | |
811 In each successive iteration, X is set to the next element of the list. If | |
812 there are no more elements, or if any element is nil (the `while' clause), | |
813 the loop exits. Otherwise, the block of code following `do' is executed.) | |
814 | |
815 This example also shows that some clauses establish variable bindings -- | |
816 essentially like a `let' binding -- and that following clauses can | |
817 reference these variables. Furthermore, the entire loop is surrounded by a | |
818 block named nil (unless the `named' clause is given), so you can return | |
819 from the loop using the macro `return'. (The other way to exit the loop is | |
820 through the macro `loop-finish'. The difference is that some loop clauses | |
821 establish or accumulate a value to be returned, and `loop-finish' returns | |
822 this. `return', however, can only return an explicitly-specified value. | |
823 NOTE CAREFULLY: There is a loop clause called `return' as well as a | |
824 standard Lisp macro called `return'. Normally they work similarly\; but if | |
825 you give the loop a name with `named', you will need to use the macro | |
826 `return-from'.) | |
827 | |
828 Another extremely useful feature of loops is called \"destructuring\". If, | |

829 in place of VAR, a list (possibly dotted, possibly a tree of arbitrary |
800 | 830 complexity) is given, the value to be assigned is assumed to have a similar |
831 structure to the list given, and variables in the list will be matched up | |
832 with corresponding elements in the structure. For example: | |
833 | |
834 \(loop | |
835 for (x y) in '((foo 1) (bar 2) (baz 3)) | |
836 do (puthash x y some-hash-table)) | |
837 | |
838 will add three elements to a hash table, mapping foo -> 1, bar -> 2, and | |
839 baz -> 3. As other examples, you can conveniently process alists using | |
840 | |
841 \(loop for (x . y) in alist do ...) | |
842 | |
843 and plists using | |
844 | |
845 \(loop for (x y) on plist by #'cddr do ...) | |
846 | |
847 Destructuring is forgiving in that mismatches in the number of elements on | |
848 either size will be handled gracefully, either by ignoring or initializing | |
1123 | 849 to nil. Destructuring is extremely powerful, and is probably the single |
850 most useful feature of `loop'. | |
851 | |
852 Other useful features of loops are iterating over hash-tables, collecting values into lists, and being able to modify lists in-place as you iterate over them. As an example of the first two, | |
853 | |
854 \(loop for x being the hash-key in table using (hash-value y) | |
855 collect (cons x y)) | |
856 | |
857 converts hash-table TABLE to an alist. (What `collect' actually does is | |
858 push its value onto the end of an internal list and establish this list as | |
859 the default return value of the loop. See below for more information.) | |
860 | |
861 An example of in-place modification is | |
862 | |
863 \(setq foo '(1 3 5)) | |
864 \(loop for x in-ref foo do | |
865 (setf x (* x x))) | |
866 | |
867 after which foo will contain '(1 9 25). | |
800 | 868 |
869 If you don't understand how a particular loop clause works, create an | |
870 example and use `macroexpand-sexp' to expand the macro. | |
871 | |
428 | 872 Valid clauses are: |
800 | 873 |
874 \(NOTE: Keywords in lowercase\; slashes separate different possibilities | |
875 for keywords, some of which are synonymous\; brackets indicate optional | |
876 parts of the clause. In all of the clauses with `being', the word `being', | |
877 the words `each' or `the', and the difference between singular and plural | |
878 keywords are all just syntactic sugar. Stylistically, you should write | |
879 either `being each foo' or `being the foos'.) | |
880 | |
881 for VAR from/upfrom/downfrom NUM1 to/upto/downto/above/below NUM2 [by NUMSTEP] | |
882 Step VAR across numbers. `upfrom', `upto', and `below' explicitly | |
883 indicate upward stepping\; `downfrom', `downto', and `above' explicitly | |
884 indicate downward stepping. (If none of these is given, the default is | |
885 upward.) `to', `upto', and `downto' cause stepping to include NUM2 as | |
886 the last iteration, while `above' and `below' stop just before reaching | |
887 NUM2. `by' can be given to indicate a stepping increment other than 1. | |
888 | |
889 for VAR in LIST [by FUNC] | |
890 Step VAR over elements of a LIST. FUNC specifies how to get successive | |
891 sublists and defaults to `cdr'. | |
892 | |
893 for VAR on LIST [by FUNC] | |
894 Step VAR over tails of a LIST. FUNC specifies how to get successive | |
895 sublists and defaults to `cdr'. | |
896 | |
897 for VAR in-ref LIST [by FUNC] | |
898 Step VAR over elements of a LIST, like `for ... in', except the VAR is | |
899 bound using `symbol-macrolet' instead of `let'. In essence, VAR is set | |
900 to a \"reference\" to the list element instead of the element itself\; | |
901 this us, you can destructively modify the list using `setf' on VAR, and | |
902 any changes to the list will \"magically\" reflect themselves in | |
903 subsequent uses of VAR. | |
904 | |
905 for VAR = INIT [then EXPR] | |
906 Set VAR on each iteration of the loop. If only INIT is given, use it | |
907 on each iteration. Otherwise, use INIT on the first iteration and EXPR | |
908 on subsequent ones. | |
909 | |
910 for VAR across/across-ref ARRAY | |
911 Step VAR across a sequence other than a list (string, vector, bit | |
912 vector). If `across-ref' is given, VAR is bound using | |
913 `symbol-macrolet' instead of `let' -- see above. | |
914 | |
915 for VAR being each/the element/elements in/of/in-ref/of-ref SEQUENCE [using (index INDEX-VAR)] | |
916 Step VAR across any sequence. A variable can be specified with a | |
917 `using' phrase to receive the index, starting at 0. If `in-ref' or | |
918 `of-ref' is given, VAR is bound using `symbol-macrolet' instead of | |
919 `let' -- see above. | |
920 | |
921 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
922 | |
923 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
924 Map VAR over a hash table. The various keywords are synonymous except | |
925 those that distinguish between keys and values. The `using' phrase is | |
926 optional and allows both key and value to be bound. | |
927 | |
928 for VAR being each/the symbol/present-symbol/external-symbol/symbols/present-symbols/external-symbols in/of OBARRAY | |
929 Map VAR over the symbols in an obarray. All symbol keywords are | |
930 currently synonymous. | |
931 | |
932 for VAR being each/the extent/extents [in/of BUFFER-OR-STRING] [from POS] [to POS] | |
933 Map VAR over the extents in a buffer or string, defaulting to the | |
934 current buffer, the beginning and the end, respectively. | |
935 | |
936 for VAR being each/the interval/intervals [in/of BUFFER-OR-STRING] [property PROPERTY] [from POS] [to POS] | |
937 Map VAR over the intervals without property change in a buffer or | |
938 string, defaulting to the current buffer, the beginning and the end, | |
939 respectively. If PROPERTY is given, iteration occurs using | |
940 `next-single-property-change'\; otherwise, using | |
941 `next-property-change'. | |
942 | |
943 for VAR being each/the window/windows [in/of FRAME] | |
944 Step VAR over the windows in FRAME, defaulting to the selected frame. | |
945 | |
946 for VAR being each/the frame/frames | |
947 Step VAR over all frames. | |
948 | |
949 for VAR being each/the buffer/buffers [by FUNC] | |
950 Step VAR over all buffers. This is actually equivalent to | |
951 `for VAR in (buffer-list) [by FUNC]'. | |
952 | |
953 for VAR being each/the key-code/key-codes/key-seq/key-seqs/key-binding/key-bindings in KEYMAP [using (key-code/key-codes/key-seq/key-seqs/key-binding/key-bindings OTHER-VAR)] | |
954 Map VAR over the entries in a keymap. Keyword `key-seq' causes | |
955 recursive mapping over prefix keymaps occurring in the keymap, with VAR | |
956 getting the built-up sequence (a vector). Otherwise, mapping does not | |
957 occur recursively. `key-code' and `key-seq' refer to what is bound | |
958 (second argument of `define-key'), and `key-binding' what it's bound to | |
959 (third argument of `define-key'). | |
960 | |
961 as VAR ... | |
962 `as' is a synonym for `for'. | |
963 | |
964 and VAR ... | |
965 `and' clauses have the same syntax as `for' clauses except that the | |
966 variables in the clause are bound in parallel with a preceding | |
967 `and'/`for' clause instead of in series. | |
968 | |
969 with VAR = INIT | |
970 Set VAR to INIT once, before doing any iterations. | |
971 | |
972 repeat NUM | |
973 Exit the loop if more than NUM iterations have occurred. | |
974 | |
975 while COND | |
976 Exit the loop if COND isn't true. | |
977 | |
978 until COND | |
979 Exit the loop if COND is true. | |
980 | |
981 collect EXPR [into VAR] | |
982 Push EXPR onto the end of a list of values -- stored either in VAR or a | |
983 temporary variable that will be returned as the return value of the | |
984 loop if it terminates through an exit condition or a call to | |
985 `loop-finish'. | |
986 | |
987 append EXPR [into VAR] | |
988 Append EXPR (a list) onto the end of a list of values, like `collect'. | |
989 | |
990 nconc EXPR [into VAR] | |
991 Nconc EXPR (a list) onto the end of a list of values, like `collect'. | |
992 | |
993 concat EXPR [into VAR] | |
994 Concatenate EXPR (a string) onto the end of a string of values, like | |
995 `collect'. | |
996 | |
997 vconcat EXPR [into VAR] | |
998 Concatenate EXPR (a vector) onto the end of a vector of values, like | |
999 `collect'. | |
1000 | |
1001 bvconcat EXPR [into VAR] | |
1002 Concatenate EXPR (a bit vector) onto the end of a bit vector of values, | |
1003 like `collect'. | |
1004 | |
1005 sum EXPR [into VAR] | |
1006 Add EXPR to a value, like `collect'. | |
1007 | |
1008 count EXPR [into VAR] | |
1009 If EXPR is true, increment a value by 1, like `collect'. | |
1010 | |
1011 maximize EXPR [into VAR] | |
1012 IF EXPR is greater than a value, replace the value with EXPR, like | |
1013 `collect'. | |
1014 | |
1015 minimize EXPR [into VAR] | |
1016 IF EXPR is less than a value, replace the value with EXPR, like | |
1017 `collect'. | |
1018 | |
1019 always COND | |
1020 If COND is true, continue the loop and set the loop return value (the | |
1021 same value that's manipulated by `collect' and friends and is returned | |
1022 by a normal loop exit or an exit using `loop-finish') to t\; otherwise, | |
1023 exit the loop and return nil. The effect is to determine and return | |
1024 whether a condition is true \"always\" (all iterations of the loop). | |
1025 | |
1026 never COND | |
1027 If COND is false, continue the loop and set the loop return value (like | |
1028 `always') to t\; otherwise, exit the loop and return nil. The effect | |
1029 is to determine and return whether a condition is \"never\" true (all | |
1030 iterations of the loop). | |
1031 | |
1032 thereis COND | |
1033 If COND is true, exit the loop and return COND. | |
1034 | |
1035 if/when COND CLAUSE [and CLAUSE]... else CLAUSE [and CLAUSE...] | |
1036 If COND is true, execute the directly following clause(s)\; otherwise, | |
1037 execute the clauses following `else'. | |
1038 | |
1039 unless COND CLAUSE [and CLAUSE]... else CLAUSE [and CLAUSE...] | |
1040 If COND is false, execute the directly following clause(s)\; otherwise, execute the clauses following `else'. | |
1041 | |
1042 do EXPRS... | |
1043 Execute the expressions (any Lisp forms). | |
1044 | |
1045 initially EXPRS... | |
1046 Execute EXPR once, before doing any iterations, and after values have | |
1047 been set using `with'. | |
1048 | |
1049 finally EXPRS... | |
1050 Execute EXPR once, directly before the loop terminates. This will not | |
1051 be executed if the loop terminates prematurely as a result of `always', | |
1052 `never', `thereis', or `return'. | |
1053 | |
1054 return EXPR | |
1055 Exit from the loop and return EXPR. | |
1056 | |
1057 finally return EXPR | |
1058 Specify the value to be returned when the loop exits. (Unlike `return', | |
1059 this doesn't cause the loop to immediately exit\; it will exit whenever | |
1060 it normally would have.) This takes precedence over a return value | |
1061 specified with `collect' and friends or `always' and friends. | |
1062 | |
1063 named NAME | |
1064 Specify the name for block surrounding the loop, in place of nil. | |
1065 (See `block'.) | |

2040 (defmacro defsetf (func arg1 &rest args) | |
2041 "(defsetf NAME FUNC): define a `setf' method. | |
2042 This macro is an easy-to-use substitute for `define-setf-method' that works | |
2043 well for simple place forms. In the simple `defsetf' form, `setf's of | |
2044 the form (setf (NAME ARGS...) VAL) are transformed to function or macro | |
2045 calls of the form (FUNC ARGS... VAL). Example: (defsetf aref aset). | |
2046 Alternate form: (defsetf NAME ARGLIST (STORE) BODY...). | |
2047 Here, the above `setf' call is expanded by binding the argument forms ARGS | |
2048 according to ARGLIST, binding the value form VAL to STORE, then executing | |
2049 BODY, which must return a Lisp form that does the necessary `setf' operation. | |
2050 Actually, ARGLIST and STORE may be bound to temporary variables which are | |
2051 introduced automatically to preserve proper execution order of the arguments. | |
2052 Example: (defsetf nth (n x) (v) (list 'setcar (list 'nthcdr n x) v))." | |
