Add an implementation for #'the, cl-macs.el
lisp/ChangeLog addition:
2010-09-16 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (the): Add a docstring and an implementation for this
macro.
* bytecomp.el (byte-compile-initial-macro-environment): Add #'the
to this, checking byte-compile-delete-errors to decide whether to
make the type assertion. Change the initvalue to use backquote and
preceding commas for the lambda expressions, to allow the latter
to be compiled.

| 31 ;; These are extensions to Emacs Lisp that provide a degree of | |
| 32 ;; Common Lisp compatibility, beyond what is already built-in | |
| 33 ;; in Emacs Lisp. | |
| 34 ;; | |
| 35 ;; This package was written by Dave Gillespie; it is a complete | |
| 36 ;; rewrite of Cesar Quiroz's original cl.el package of December 1986. | |

| 41 ;; package which should be autoloaded, but need only be present | |

250 the expansion of BODY. See the ENVIRONMENT argument to `macroexpand'. |
| 872 | 251 |
| 252 -- The macro arg list syntax allows for \"destructuring\" -- see also | |
| 253 `destructuring-bind', which destructures exactly like `defmacro*', and | |
| 254 `loop', which does a rather different way of destructuring. Anywhere | |
| 255 that a simple argument may appear, and (if following a lambda-list | |
| 256 keyword) a list may not normally appear, an embedded lambda list can be | |
| 257 substituted. (The format of the embedded lambda list is exactly the | |
| 258 same as for a top-level list except that &environment is not allowed.) | |
| 259 When matching this lambda list against a caller-specified argument, that | |
| 260 argument is treated as a list and normal lambda-list processing occurs, | |
| 261 just as if the entire operation were happening at top level. | |
| 262 Furthermore, any lambda list, embedded or top-level, can be dotted at its | |
| 263 end, and this will cause matching with an appropriate dotted list given | |
| 264 as an argument. | |
| 265 | |
| 266 See `loop' for practical examples of destructuring, but | |
| 267 keep in mind that `loop' destructuring is somewhat different from macro | |
| 268 destructuring in that | |
| 269 | |
| 270 (a) Macro destructuring has extra features in the various lambda-list | |
| 271 keywords, allowing for special processing of a list other than just | |
| 272 simple matching. | |
| 273 (b) Macro destructuring is strict, in that an error is signalled if the | |
| 274 actual structure does not match the expected structure. On the | |
| 275 other hand, loop destructuring is lax -- extra arguments in a list | |
| 276 are ignored, not enough arguments cause the remaining parameters to | |
| 277 receive a value of nil, etc. | |

| 553 This is similar to `let' but it does \"destructuring\", in that it matches | |
| 554 the structure of ARGS to the structure of EXPR and binds corresponding | |
| 555 arguments in ARGS to their values in EXPR. The format of ARGS, and the | |
| 556 way the destructuring works, is exactly like the destructuring that occurs | |
| 557 in `defmacro*'; see that for more information. | |
| 558 | |
| 559 An alternative means of destructuring is using the `loop' macro. `loop' | |
| 560 gives practical examples of destructuring. `defmacro*' describes the | |
| 561 differences between loop and macro-style destructuring. | |
| 562 | |
| 563 You can rewrite a call to (destructuring-bind ARGS EXPR &rest BODY) using | |
| 564 `loop', approximately like this: | |
| 565 | |
| 566 (loop for ARGS = EXPR | |
| 567 return (progn BODY)) | |

802 "The Common Lisp `loop' macro. |
| 800 | 803 |
| 804 The loop macro consists of a series of clauses, which do things like | |
| 805 iterate variables, set conditions for exiting the loop, accumulating values | |
| 806 to be returned as the return value of the loop, and executing arbitrary | |
| 2297 | 807 blocks of code. Each clause is processed in turn, and the loop executes its |
| 800 | 808 body repeatedly until an exit condition is hit. |
| 809 | |
| 810 It's important to understand that loop clauses such as `for' and `while', | |
| 811 which look like loop-establishing constructs, don't actually *establish* a | |
| 812 loop\; the looping is established by the `loop' clause itself, which will | |
| 813 repeatedly process its body until told to stop. `while' merely establishes | |
| 814 a condition which, when true, causes the loop to finish, and `for' sets a | |
| 815 variable to different values on each iteration (e.g. successive elements of | |
| 816 a list) and sets an exit condition when there are no more values. This | |
| 817 means, for example, that if two `for' clauses appear, you don't get two | |
| 818 nested loops, but instead two variables that are stepped in parallel, and | |
| 819 two exit conditions, either of which, if triggered, will cause the loop to | |
| 820 end. Similarly for a loop with a `for' and a `while' clause. For example: | |
| 821 | |
| 822 \(loop | |
| 823 for x in list | |
| 824 while x | |
| 825 do ...) | |
| 826 | |
| 827 In each successive iteration, X is set to the next element of the list. If | |
| 828 there are no more elements, or if any element is nil (the `while' clause), | |
| 829 the loop exits. Otherwise, the block of code following `do' is executed.) | |
| 830 | |
| 831 This example also shows that some clauses establish variable bindings -- | |
| 832 essentially like a `let' binding -- and that following clauses can | |
| 833 reference these variables. Furthermore, the entire loop is surrounded by a | |
| 834 block named nil (unless the `named' clause is given), so you can return | |
| 835 from the loop using the macro `return'. (The other way to exit the loop is | |
| 836 through the macro `loop-finish'. The difference is that some loop clauses | |
| 837 establish or accumulate a value to be returned, and `loop-finish' returns | |
| 838 this. `return', however, can only return an explicitly-specified value. | |
| 839 NOTE CAREFULLY: There is a loop clause called `return' as well as a | |
| 840 standard Lisp macro called `return'. Normally they work similarly\; but if | |
| 841 you give the loop a name with `named', you will need to use the macro | |
| 842 `return-from'.) | |
| 843 | |
| 844 Another extremely useful feature of loops is called \"destructuring\". If, | |
| 845 in place of VAR, a list (possibly dotted, possibly a tree of arbitary | |
| 846 complexity) is given, the value to be assigned is assumed to have a similar | |
| 847 structure to the list given, and variables in the list will be matched up | |
| 848 with corresponding elements in the structure. For example: | |
| 849 | |
| 850 \(loop | |
| 851 for (x y) in '((foo 1) (bar 2) (baz 3)) | |
| 852 do (puthash x y some-hash-table)) | |
| 853 | |
| 854 will add three elements to a hash table, mapping foo -> 1, bar -> 2, and | |
| 855 baz -> 3. As other examples, you can conveniently process alists using | |
| 856 | |
| 857 \(loop for (x . y) in alist do ...) | |
| 858 | |
| 859 and plists using | |
| 860 | |
| 861 \(loop for (x y) on plist by #'cddr do ...) | |
| 862 | |
| 863 Destructuring is forgiving in that mismatches in the number of elements on | |
| 864 either size will be handled gracefully, either by ignoring or initializing | |
| 1123 | 865 to nil. Destructuring is extremely powerful, and is probably the single |
| 866 most useful feature of `loop'. | |
| 867 | |
| 868 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, | |
| 869 | |
| 870 \(loop for x being the hash-key in table using (hash-value y) | |
| 871 collect (cons x y)) | |
| 872 | |
| 873 converts hash-table TABLE to an alist. (What `collect' actually does is | |
| 874 push its value onto the end of an internal list and establish this list as | |
| 875 the default return value of the loop. See below for more information.) | |
| 876 | |
| 877 An example of in-place modification is | |
| 878 | |
| 879 \(setq foo '(1 3 5)) | |
| 880 \(loop for x in-ref foo do | |
| 881 (setf x (* x x))) | |
| 882 | |
| 883 after which foo will contain '(1 9 25). | |
| 800 | 884 |
| 885 If you don't understand how a particular loop clause works, create an | |
| 886 example and use `macroexpand-sexp' to expand the macro. | |
| 887 | |
| 428 | 888 Valid clauses are: |
| 800 | 889 |
| 890 \(NOTE: Keywords in lowercase\; slashes separate different possibilities | |
| 891 for keywords, some of which are synonymous\; brackets indicate optional | |
| 892 parts of the clause. In all of the clauses with `being', the word `being', | |
| 893 the words `each' or `the', and the difference between singular and plural | |
| 894 keywords are all just syntactic sugar. Stylistically, you should write | |
| 895 either `being each foo' or `being the foos'.) | |
| 896 | |
| 897 for VAR from/upfrom/downfrom NUM1 to/upto/downto/above/below NUM2 [by NUMSTEP] | |
| 898 Step VAR across numbers. `upfrom', `upto', and `below' explicitly | |
| 899 indicate upward stepping\; `downfrom', `downto', and `above' explicitly | |
| 900 indicate downward stepping. (If none of these is given, the default is | |
| 901 upward.) `to', `upto', and `downto' cause stepping to include NUM2 as | |
| 902 the last iteration, while `above' and `below' stop just before reaching | |
| 903 NUM2. `by' can be given to indicate a stepping increment other than 1. | |
| 904 | |
| 905 for VAR in LIST [by FUNC] | |
| 906 Step VAR over elements of a LIST. FUNC specifies how to get successive | |
| 907 sublists and defaults to `cdr'. | |
| 908 | |
| 909 for VAR on LIST [by FUNC] | |
| 910 Step VAR over tails of a LIST. FUNC specifies how to get successive | |
| 911 sublists and defaults to `cdr'. | |
| 912 | |
| 913 for VAR in-ref LIST [by FUNC] | |
| 914 Step VAR over elements of a LIST, like `for ... in', except the VAR is | |
| 915 bound using `symbol-macrolet' instead of `let'. In essence, VAR is set | |
| 916 to a \"reference\" to the list element instead of the element itself\; | |
| 917 this us, you can destructively modify the list using `setf' on VAR, and | |
| 918 any changes to the list will \"magically\" reflect themselves in | |
| 919 subsequent uses of VAR. | |
| 920 | |
| 921 for VAR = INIT [then EXPR] | |
| 922 Set VAR on each iteration of the loop. If only INIT is given, use it | |
| 923 on each iteration. Otherwise, use INIT on the first iteration and EXPR | |
| 924 on subsequent ones. | |
| 925 | |
| 926 for VAR across/across-ref ARRAY | |
| 927 Step VAR across a sequence other than a list (string, vector, bit | |
| 928 vector). If `across-ref' is given, VAR is bound using | |
| 929 `symbol-macrolet' instead of `let' -- see above. | |
| 930 | |
| 931 for VAR being each/the element/elements in/of/in-ref/of-ref SEQUENCE [using (index INDEX-VAR)] | |
| 932 Step VAR across any sequence. A variable can be specified with a | |
| 933 `using' phrase to receive the index, starting at 0. If `in-ref' or | |
| 934 `of-ref' is given, VAR is bound using `symbol-macrolet' instead of | |
| 935 `let' -- see above. | |
| 936 | |
| 937 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
| 938 | |
| 939 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
| 940 Map VAR over a hash table. The various keywords are synonymous except | |
| 941 those that distinguish between keys and values. The `using' phrase is | |
| 942 optional and allows both key and value to be bound. | |
| 943 | |
| 944 for VAR being each/the symbol/present-symbol/external-symbol/symbols/present-symbols/external-symbols in/of OBARRAY | |
| 945 Map VAR over the symbols in an obarray. All symbol keywords are | |
| 946 currently synonymous. | |
| 947 | |
| 948 for VAR being each/the extent/extents [in/of BUFFER-OR-STRING] [from POS] [to POS] | |
| 949 Map VAR over the extents in a buffer or string, defaulting to the | |
| 950 current buffer, the beginning and the end, respectively. | |
| 951 | |
| 952 for VAR being each/the interval/intervals [in/of BUFFER-OR-STRING] [property PROPERTY] [from POS] [to POS] | |
| 953 Map VAR over the intervals without property change in a buffer or | |
| 954 string, defaulting to the current buffer, the beginning and the end, | |
| 955 respectively. If PROPERTY is given, iteration occurs using | |
| 956 `next-single-property-change'\; otherwise, using | |
| 957 `next-property-change'. | |
| 958 | |
| 959 for VAR being each/the window/windows [in/of FRAME] | |
| 960 Step VAR over the windows in FRAME, defaulting to the selected frame. | |
| 961 | |
| 962 for VAR being each/the frame/frames | |
| 963 Step VAR over all frames. | |
| 964 | |
| 965 for VAR being each/the buffer/buffers [by FUNC] | |
| 966 Step VAR over all buffers. This is actually equivalent to | |
| 967 `for VAR in (buffer-list) [by FUNC]'. | |
| 968 | |
| 969 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)] | |
| 970 Map VAR over the entries in a keymap. Keyword `key-seq' causes | |
| 971 recursive mapping over prefix keymaps occurring in the keymap, with VAR | |
| 972 getting the built-up sequence (a vector). Otherwise, mapping does not | |
| 973 occur recursively. `key-code' and `key-seq' refer to what is bound | |
| 974 (second argument of `define-key'), and `key-binding' what it's bound to | |
| 975 (third argument of `define-key'). | |
| 976 | |
| 977 as VAR ... | |
| 978 `as' is a synonym for `for'. | |
| 979 | |
| 980 and VAR ... | |
| 981 `and' clauses have the same syntax as `for' clauses except that the | |
| 982 variables in the clause are bound in parallel with a preceding | |
| 983 `and'/`for' clause instead of in series. | |
| 984 | |
| 985 with VAR = INIT | |
| 986 Set VAR to INIT once, before doing any iterations. | |
| 987 | |
| 988 repeat NUM | |
| 989 Exit the loop if more than NUM iterations have occurred. | |
| 990 | |
| 991 while COND | |
| 992 Exit the loop if COND isn't true. | |
| 993 | |
| 994 until COND | |
| 995 Exit the loop if COND is true. | |
| 996 | |
| 997 collect EXPR [into VAR] | |
| 998 Push EXPR onto the end of a list of values -- stored either in VAR or a | |
| 999 temporary variable that will be returned as the return value of the | |
| 1000 loop if it terminates through an exit condition or a call to | |
| 1001 `loop-finish'. | |
| 1002 | |
| 1003 append EXPR [into VAR] | |
| 1004 Append EXPR (a list) onto the end of a list of values, like `collect'. | |
| 1005 | |
| 1006 nconc EXPR [into VAR] | |
| 1007 Nconc EXPR (a list) onto the end of a list of values, like `collect'. | |
| 1008 | |
| 1009 concat EXPR [into VAR] | |
| 1010 Concatenate EXPR (a string) onto the end of a string of values, like | |
| 1011 `collect'. | |
| 1012 | |
| 1013 vconcat EXPR [into VAR] | |
| 1014 Concatenate EXPR (a vector) onto the end of a vector of values, like | |
| 1015 `collect'. | |
| 1016 | |
| 1017 bvconcat EXPR [into VAR] | |
| 1018 Concatenate EXPR (a bit vector) onto the end of a bit vector of values, | |
| 1019 like `collect'. | |
| 1020 | |
| 1021 sum EXPR [into VAR] | |
| 1022 Add EXPR to a value, like `collect'. | |
| 1023 | |
| 1024 count EXPR [into VAR] | |
| 1025 If EXPR is true, increment a value by 1, like `collect'. | |
| 1026 | |
| 1027 maximize EXPR [into VAR] | |
| 1028 IF EXPR is greater than a value, replace the value with EXPR, like | |
| 1029 `collect'. | |
| 1030 | |
| 1031 minimize EXPR [into VAR] | |
| 1032 IF EXPR is less than a value, replace the value with EXPR, like | |
| 1033 `collect'. | |
| 1034 | |
| 1035 always COND | |
| 1036 If COND is true, continue the loop and set the loop return value (the | |
| 1037 same value that's manipulated by `collect' and friends and is returned | |
| 1038 by a normal loop exit or an exit using `loop-finish') to t\; otherwise, | |
| 1039 exit the loop and return nil. The effect is to determine and return | |
| 1040 whether a condition is true \"always\" (all iterations of the loop). | |
| 1041 | |
| 1042 never COND | |
| 1043 If COND is false, continue the loop and set the loop return value (like | |
| 1044 `always') to t\; otherwise, exit the loop and return nil. The effect | |
| 1045 is to determine and return whether a condition is \"never\" true (all | |
| 1046 iterations of the loop). | |
| 1047 | |
| 1048 thereis COND | |
| 1049 If COND is true, exit the loop and return COND. | |
| 1050 | |
| 1051 if/when COND CLAUSE [and CLAUSE]... else CLAUSE [and CLAUSE...] | |
| 1052 If COND is true, execute the directly following clause(s)\; otherwise, | |
| 1053 execute the clauses following `else'. | |
| 1054 | |
| 1055 unless COND CLAUSE [and CLAUSE]... else CLAUSE [and CLAUSE...] | |
| 1056 If COND is false, execute the directly following clause(s)\; otherwise, execute the clauses following `else'. | |
| 1057 | |
| 1058 do EXPRS... | |
| 1059 Execute the expressions (any Lisp forms). | |
| 1060 | |
| 1061 initially EXPRS... | |
| 1062 Execute EXPR once, before doing any iterations, and after values have | |
| 1063 been set using `with'. | |
| 1064 | |
| 1065 finally EXPRS... | |
| 1066 Execute EXPR once, directly before the loop terminates. This will not | |
| 1067 be executed if the loop terminates prematurely as a result of `always', | |
| 1068 `never', `thereis', or `return'. | |
| 1069 | |
| 1070 return EXPR | |
| 1071 Exit from the loop and return EXPR. | |
| 1072 | |
| 1073 finally return EXPR | |
| 1074 Specify the value to be returned when the loop exits. (Unlike `return', | |
| 1075 this doesn't cause the loop to immediately exit\; it will exit whenever | |
| 1076 it normally would have.) This takes precedence over a return value | |
| 1077 specified with `collect' and friends or `always' and friends. | |
| 1078 | |
| 1079 named NAME | |
| 1080 Specify the name for block surrounding the loop, in place of nil. | |
| 1081 (See `block'.) | |

| 2056 return a list of five elements: a temporary-variables list, a value-forms | |
| 2057 list, a store-variables list (of length one), a store-form, and an access- | |

| 2068 (defmacro defsetf (func arg1 &rest args) | |
| 2069 "(defsetf NAME FUNC): define a `setf' method. | |
| 2070 This macro is an easy-to-use substitute for `define-setf-method' that works | |
| 2071 well for simple place forms. In the simple `defsetf' form, `setf's of | |
| 2072 the form (setf (NAME ARGS...) VAL) are transformed to function or macro | |
| 2073 calls of the form (FUNC ARGS... VAL). Example: (defsetf aref aset). | |
| 2074 Alternate form: (defsetf NAME ARGLIST (STORE) BODY...). | |
| 2075 Here, the above `setf' call is expanded by binding the argument forms ARGS | |
| 2076 according to ARGLIST, binding the value form VAL to STORE, then executing | |
| 2077 BODY, which must return a Lisp form that does the necessary `setf' operation. | |
| 2078 Actually, ARGLIST and STORE may be bound to temporary variables which are | |
| 2079 introduced automatically to preserve proper execution order of the arguments. | |
| 2080 Example: (defsetf nth (n x) (v) (list 'setcar (list 'nthcdr n x) v))." | |
