annotate lisp/cl-macs.el @ 5658:289cf21be887
Don't augment ENVIRONMENT when that's not indicated, #'macroexpand.
This reflects better understanding on my part of the &environment macro
keyword, and I've expanded the Lisp manual and docstrings to reflect that.
lisp/ChangeLog addition:
2012-05-06 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (block): Comment on why we can't use &environment
here.
* cl-macs.el (defmacro*): Document &environment in more detail.
* cl-macs.el (macrolet): Use &environment, instead of referencing
byte-compile-macro-environment directly.
* cl-macs.el (symbol-macrolet): Ditto.
* cl-macs.el (lexical-let): Ditto.
* cl-macs.el (labels): Ditto.
man/ChangeLog addition:
2012-05-06 Aidan Kehoe <kehoea@parhasard.net>
* lispref/macros.texi (Expansion):
Cross-reference to documentation of #'cl-prettyexpand, #'defmacro*
when talking about #'macroexpand.
tests/ChangeLog addition:
2012-05-06 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Use &environment appropriately in #'macrolet, instead of relying
on #'macroexpand to guess what we mean.

237 argument to `macroexpand'. |
| 872 | 238 |
| 239 -- The macro arg list syntax allows for \"destructuring\" -- see also | |
| 240 `destructuring-bind', which destructures exactly like `defmacro*', and | |
| 241 `loop', which does a rather different way of destructuring. Anywhere | |
| 242 that a simple argument may appear, and (if following a lambda-list | |
| 243 keyword) a list may not normally appear, an embedded lambda list can be | |
| 244 substituted. (The format of the embedded lambda list is exactly the | |
| 245 same as for a top-level list except that &environment is not allowed.) | |
| 246 When matching this lambda list against a caller-specified argument, that | |
| 247 argument is treated as a list and normal lambda-list processing occurs, | |
| 248 just as if the entire operation were happening at top level. | |
| 249 Furthermore, any lambda list, embedded or top-level, can be dotted at its | |
| 250 end, and this will cause matching with an appropriate dotted list given | |
| 251 as an argument. | |
| 252 | |
| 253 See `loop' for practical examples of destructuring, but | |
| 254 keep in mind that `loop' destructuring is somewhat different from macro | |
| 255 destructuring in that | |
| 256 | |
| 257 (a) Macro destructuring has extra features in the various lambda-list | |
| 258 keywords, allowing for special processing of a list other than just | |
| 259 simple matching. | |
| 260 (b) Macro destructuring is strict, in that an error is signalled if the | |
| 261 actual structure does not match the expected structure. On the | |
| 262 other hand, loop destructuring is lax -- extra arguments in a list | |
| 263 are ignored, not enough arguments cause the remaining parameters to | |
| 264 receive a value of nil, etc. | |

| 872 | 552 "Bind the arguments in ARGS to EXPR then eval BODY. |
| 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)) | |
| 568 | |
| 569 I say \"approximately\" because the destructuring works in a somewhat | |
| 570 different fashion, although for most reasonably simple constructs the | |
| 571 results will be the same." | |

758 "The Common Lisp `loop' macro. |
| 800 | 759 |
| 760 The loop macro consists of a series of clauses, which do things like | |
| 761 iterate variables, set conditions for exiting the loop, accumulating values | |
| 762 to be returned as the return value of the loop, and executing arbitrary | |
| 2297 | 763 blocks of code. Each clause is processed in turn, and the loop executes its |
| 800 | 764 body repeatedly until an exit condition is hit. |
| 765 | |
| 766 It's important to understand that loop clauses such as `for' and `while', | |
| 767 which look like loop-establishing constructs, don't actually *establish* a | |
| 768 loop\; the looping is established by the `loop' clause itself, which will | |
| 769 repeatedly process its body until told to stop. `while' merely establishes | |
| 770 a condition which, when true, causes the loop to finish, and `for' sets a | |
| 771 variable to different values on each iteration (e.g. successive elements of | |
| 772 a list) and sets an exit condition when there are no more values. This | |
| 773 means, for example, that if two `for' clauses appear, you don't get two | |
| 774 nested loops, but instead two variables that are stepped in parallel, and | |
| 775 two exit conditions, either of which, if triggered, will cause the loop to | |
| 776 end. Similarly for a loop with a `for' and a `while' clause. For example: | |
| 777 | |
| 778 \(loop | |
| 779 for x in list | |
| 780 while x | |
| 781 do ...) | |
| 782 | |
| 783 In each successive iteration, X is set to the next element of the list. If | |
| 784 there are no more elements, or if any element is nil (the `while' clause), | |
| 785 the loop exits. Otherwise, the block of code following `do' is executed.) | |
| 786 | |
| 787 This example also shows that some clauses establish variable bindings -- | |
| 788 essentially like a `let' binding -- and that following clauses can | |
| 789 reference these variables. Furthermore, the entire loop is surrounded by a | |
| 790 block named nil (unless the `named' clause is given), so you can return | |
| 791 from the loop using the macro `return'. (The other way to exit the loop is | |
| 792 through the macro `loop-finish'. The difference is that some loop clauses | |
| 793 establish or accumulate a value to be returned, and `loop-finish' returns | |
| 794 this. `return', however, can only return an explicitly-specified value. | |
| 795 NOTE CAREFULLY: There is a loop clause called `return' as well as a | |
| 796 standard Lisp macro called `return'. Normally they work similarly\; but if | |
| 797 you give the loop a name with `named', you will need to use the macro | |
| 798 `return-from'.) | |
| 799 | |
| 800 Another extremely useful feature of loops is called \"destructuring\". If, | |

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

| 1957 (defmacro defsetf (func arg1 &rest args) | |
| 1958 "(defsetf NAME FUNC): define a `setf' method. | |
| 1959 This macro is an easy-to-use substitute for `define-setf-method' that works | |
| 1960 well for simple place forms. In the simple `defsetf' form, `setf's of | |
| 1961 the form (setf (NAME ARGS...) VAL) are transformed to function or macro | |
| 1962 calls of the form (FUNC ARGS... VAL). Example: (defsetf aref aset). | |
| 1963 Alternate form: (defsetf NAME ARGLIST (STORE) BODY...). | |
| 1964 Here, the above `setf' call is expanded by binding the argument forms ARGS | |
| 1965 according to ARGLIST, binding the value form VAL to STORE, then executing | |
| 1966 BODY, which must return a Lisp form that does the necessary `setf' operation. | |
| 1967 Actually, ARGLIST and STORE may be bound to temporary variables which are | |
| 1968 introduced automatically to preserve proper execution order of the arguments. | |
| 1969 Example: (defsetf nth (n x) (v) (list 'setcar (list 'nthcdr n x) v))." | |
