annotate lisp/cl-macs.el @ 5574:d4f334808463
Support inlining labels, bytecomp.el.
lisp/ChangeLog addition:
2011-10-02 Aidan Kehoe <kehoea@parhasard.net>
* bytecomp.el (byte-compile-initial-macro-environment):
Add #'declare to this, so it doesn't need to rely on
#'cl-compiling file to determine when we're byte-compiling.
Update #'labels to support declaring labels inline, as Common Lisp
requires.
* bytecomp.el (byte-compile-function-form):
Don't error if FUNCTION is quoting a non-lambda, non-symbol, just
return it.
* cl-extra.el (cl-macroexpand-all):
If a label name has been quoted, expand to the label placeholder
quoted with 'function. This allows the byte compiler to
distinguish between uses of the placeholder as data and uses in
contexts where it should be inlined.
* cl-macs.el:
* cl-macs.el (cl-do-proclaim):
When proclaming something as inline, if it is bound as a label,
don't modify the symbol's plist; instead, treat the first element
of its placeholder constant vector as a place to store compile
information.
* cl-macs.el (declare):
Leave processing declarations while compiling to the
implementation of #'declare in
byte-compile-initial-macro-environment.
tests/ChangeLog addition:
2011-10-02 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
* automated/lisp-tests.el (+):
Test #'labels and inlining.

| 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. | |

251 the expansion of BODY. See the ENVIRONMENT argument to `macroexpand'. |
| 872 | 252 |
| 253 -- The macro arg list syntax allows for \"destructuring\" -- see also | |
| 254 `destructuring-bind', which destructures exactly like `defmacro*', and | |
| 255 `loop', which does a rather different way of destructuring. Anywhere | |
| 256 that a simple argument may appear, and (if following a lambda-list | |
| 257 keyword) a list may not normally appear, an embedded lambda list can be | |
| 258 substituted. (The format of the embedded lambda list is exactly the | |
| 259 same as for a top-level list except that &environment is not allowed.) | |
| 260 When matching this lambda list against a caller-specified argument, that | |
| 261 argument is treated as a list and normal lambda-list processing occurs, | |
| 262 just as if the entire operation were happening at top level. | |
| 263 Furthermore, any lambda list, embedded or top-level, can be dotted at its | |
| 264 end, and this will cause matching with an appropriate dotted list given | |
| 265 as an argument. | |
| 266 | |
| 267 See `loop' for practical examples of destructuring, but | |
| 268 keep in mind that `loop' destructuring is somewhat different from macro | |
| 269 destructuring in that | |
| 270 | |
| 271 (a) Macro destructuring has extra features in the various lambda-list | |
| 272 keywords, allowing for special processing of a list other than just | |
| 273 simple matching. | |
| 274 (b) Macro destructuring is strict, in that an error is signalled if the | |
| 275 actual structure does not match the expected structure. On the | |
| 276 other hand, loop destructuring is lax -- extra arguments in a list | |
| 277 are ignored, not enough arguments cause the remaining parameters to | |
| 278 receive a value of nil, etc. | |

| 565 This is similar to `let' but it does \"destructuring\", in that it matches | |
| 566 the structure of ARGS to the structure of EXPR and binds corresponding | |
| 567 arguments in ARGS to their values in EXPR. The format of ARGS, and the | |
| 568 way the destructuring works, is exactly like the destructuring that occurs | |
| 569 in `defmacro*'; see that for more information. | |
| 570 | |
| 571 An alternative means of destructuring is using the `loop' macro. `loop' | |
| 572 gives practical examples of destructuring. `defmacro*' describes the | |
| 573 differences between loop and macro-style destructuring. | |
| 574 | |
| 575 You can rewrite a call to (destructuring-bind ARGS EXPR &rest BODY) using | |
| 576 `loop', approximately like this: | |
| 577 | |
| 578 (loop for ARGS = EXPR | |
| 579 return (progn BODY)) | |
| 580 | |
| 581 I say \"approximately\" because the destructuring works in a somewhat | |
| 582 different fashion, although for most reasonably simple constructs the | |
| 583 results will be the same." | |

774 "The Common Lisp `loop' macro. |
| 800 | 775 |
| 776 The loop macro consists of a series of clauses, which do things like | |
| 777 iterate variables, set conditions for exiting the loop, accumulating values | |
| 778 to be returned as the return value of the loop, and executing arbitrary | |
| 2297 | 779 blocks of code. Each clause is processed in turn, and the loop executes its |
| 800 | 780 body repeatedly until an exit condition is hit. |
| 781 | |
| 782 It's important to understand that loop clauses such as `for' and `while', | |
| 783 which look like loop-establishing constructs, don't actually *establish* a | |
| 784 loop\; the looping is established by the `loop' clause itself, which will | |
| 785 repeatedly process its body until told to stop. `while' merely establishes | |
| 786 a condition which, when true, causes the loop to finish, and `for' sets a | |
| 787 variable to different values on each iteration (e.g. successive elements of | |
| 788 a list) and sets an exit condition when there are no more values. This | |
| 789 means, for example, that if two `for' clauses appear, you don't get two | |
| 790 nested loops, but instead two variables that are stepped in parallel, and | |
| 791 two exit conditions, either of which, if triggered, will cause the loop to | |
| 792 end. Similarly for a loop with a `for' and a `while' clause. For example: | |
| 793 | |
| 794 \(loop | |
| 795 for x in list | |
| 796 while x | |
| 797 do ...) | |
| 798 | |
| 799 In each successive iteration, X is set to the next element of the list. If | |
| 800 there are no more elements, or if any element is nil (the `while' clause), | |
| 801 the loop exits. Otherwise, the block of code following `do' is executed.) | |
| 802 | |
| 803 This example also shows that some clauses establish variable bindings -- | |
| 804 essentially like a `let' binding -- and that following clauses can | |
| 805 reference these variables. Furthermore, the entire loop is surrounded by a | |
| 806 block named nil (unless the `named' clause is given), so you can return | |
| 807 from the loop using the macro `return'. (The other way to exit the loop is | |
| 808 through the macro `loop-finish'. The difference is that some loop clauses | |
| 809 establish or accumulate a value to be returned, and `loop-finish' returns | |
| 810 this. `return', however, can only return an explicitly-specified value. | |
| 811 NOTE CAREFULLY: There is a loop clause called `return' as well as a | |
| 812 standard Lisp macro called `return'. Normally they work similarly\; but if | |
| 813 you give the loop a name with `named', you will need to use the macro | |
| 814 `return-from'.) | |
| 815 | |
| 816 Another extremely useful feature of loops is called \"destructuring\". If, | |

817 in place of VAR, a list (possibly dotted, possibly a tree of arbitrary |
| 800 | 818 complexity) is given, the value to be assigned is assumed to have a similar |
| 819 structure to the list given, and variables in the list will be matched up | |
| 820 with corresponding elements in the structure. For example: | |
| 821 | |
| 822 \(loop | |
| 823 for (x y) in '((foo 1) (bar 2) (baz 3)) | |
| 824 do (puthash x y some-hash-table)) | |
| 825 | |
| 826 will add three elements to a hash table, mapping foo -> 1, bar -> 2, and | |
| 827 baz -> 3. As other examples, you can conveniently process alists using | |
| 828 | |
| 829 \(loop for (x . y) in alist do ...) | |
| 830 | |
| 831 and plists using | |
| 832 | |
| 833 \(loop for (x y) on plist by #'cddr do ...) | |
| 834 | |
| 835 Destructuring is forgiving in that mismatches in the number of elements on | |
| 836 either size will be handled gracefully, either by ignoring or initializing | |
| 1123 | 837 to nil. Destructuring is extremely powerful, and is probably the single |
| 838 most useful feature of `loop'. | |
| 839 | |
| 840 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, | |
| 841 | |
| 842 \(loop for x being the hash-key in table using (hash-value y) | |
| 843 collect (cons x y)) | |
| 844 | |
| 845 converts hash-table TABLE to an alist. (What `collect' actually does is | |
| 846 push its value onto the end of an internal list and establish this list as | |
| 847 the default return value of the loop. See below for more information.) | |
| 848 | |
| 849 An example of in-place modification is | |
| 850 | |
| 851 \(setq foo '(1 3 5)) | |
| 852 \(loop for x in-ref foo do | |
| 853 (setf x (* x x))) | |
| 854 | |
| 855 after which foo will contain '(1 9 25). | |
| 800 | 856 |
| 857 If you don't understand how a particular loop clause works, create an | |
| 858 example and use `macroexpand-sexp' to expand the macro. | |
| 859 | |
| 428 | 860 Valid clauses are: |
| 800 | 861 |
| 862 \(NOTE: Keywords in lowercase\; slashes separate different possibilities | |
| 863 for keywords, some of which are synonymous\; brackets indicate optional | |
| 864 parts of the clause. In all of the clauses with `being', the word `being', | |
| 865 the words `each' or `the', and the difference between singular and plural | |
| 866 keywords are all just syntactic sugar. Stylistically, you should write | |
| 867 either `being each foo' or `being the foos'.) | |
| 868 | |
| 869 for VAR from/upfrom/downfrom NUM1 to/upto/downto/above/below NUM2 [by NUMSTEP] | |
| 870 Step VAR across numbers. `upfrom', `upto', and `below' explicitly | |
| 871 indicate upward stepping\; `downfrom', `downto', and `above' explicitly | |
| 872 indicate downward stepping. (If none of these is given, the default is | |
| 873 upward.) `to', `upto', and `downto' cause stepping to include NUM2 as | |
| 874 the last iteration, while `above' and `below' stop just before reaching | |
| 875 NUM2. `by' can be given to indicate a stepping increment other than 1. | |
| 876 | |
| 877 for VAR in LIST [by FUNC] | |
| 878 Step VAR over elements of a LIST. FUNC specifies how to get successive | |
| 879 sublists and defaults to `cdr'. | |
| 880 | |
| 881 for VAR on LIST [by FUNC] | |
| 882 Step VAR over tails of a LIST. FUNC specifies how to get successive | |
| 883 sublists and defaults to `cdr'. | |
| 884 | |
| 885 for VAR in-ref LIST [by FUNC] | |
| 886 Step VAR over elements of a LIST, like `for ... in', except the VAR is | |
| 887 bound using `symbol-macrolet' instead of `let'. In essence, VAR is set | |
| 888 to a \"reference\" to the list element instead of the element itself\; | |
| 889 this us, you can destructively modify the list using `setf' on VAR, and | |
| 890 any changes to the list will \"magically\" reflect themselves in | |
| 891 subsequent uses of VAR. | |
| 892 | |
| 893 for VAR = INIT [then EXPR] | |
| 894 Set VAR on each iteration of the loop. If only INIT is given, use it | |
| 895 on each iteration. Otherwise, use INIT on the first iteration and EXPR | |
| 896 on subsequent ones. | |
| 897 | |
| 898 for VAR across/across-ref ARRAY | |
| 899 Step VAR across a sequence other than a list (string, vector, bit | |
| 900 vector). If `across-ref' is given, VAR is bound using | |
| 901 `symbol-macrolet' instead of `let' -- see above. | |
| 902 | |
| 903 for VAR being each/the element/elements in/of/in-ref/of-ref SEQUENCE [using (index INDEX-VAR)] | |
| 904 Step VAR across any sequence. A variable can be specified with a | |
| 905 `using' phrase to receive the index, starting at 0. If `in-ref' or | |
| 906 `of-ref' is given, VAR is bound using `symbol-macrolet' instead of | |
| 907 `let' -- see above. | |
| 908 | |
| 909 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
| 910 | |
| 911 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
| 912 Map VAR over a hash table. The various keywords are synonymous except | |
| 913 those that distinguish between keys and values. The `using' phrase is | |
| 914 optional and allows both key and value to be bound. | |
| 915 | |
| 916 for VAR being each/the symbol/present-symbol/external-symbol/symbols/present-symbols/external-symbols in/of OBARRAY | |
| 917 Map VAR over the symbols in an obarray. All symbol keywords are | |
| 918 currently synonymous. | |
| 919 | |
| 920 for VAR being each/the extent/extents [in/of BUFFER-OR-STRING] [from POS] [to POS] | |
| 921 Map VAR over the extents in a buffer or string, defaulting to the | |
| 922 current buffer, the beginning and the end, respectively. | |
| 923 | |
| 924 for VAR being each/the interval/intervals [in/of BUFFER-OR-STRING] [property PROPERTY] [from POS] [to POS] | |
| 925 Map VAR over the intervals without property change in a buffer or | |
| 926 string, defaulting to the current buffer, the beginning and the end, | |
| 927 respectively. If PROPERTY is given, iteration occurs using | |
| 928 `next-single-property-change'\; otherwise, using | |
| 929 `next-property-change'. | |
| 930 | |
| 931 for VAR being each/the window/windows [in/of FRAME] | |
| 932 Step VAR over the windows in FRAME, defaulting to the selected frame. | |
| 933 | |
| 934 for VAR being each/the frame/frames | |
| 935 Step VAR over all frames. | |
| 936 | |
| 937 for VAR being each/the buffer/buffers [by FUNC] | |
| 938 Step VAR over all buffers. This is actually equivalent to | |
| 939 `for VAR in (buffer-list) [by FUNC]'. | |
| 940 | |
| 941 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)] | |
| 942 Map VAR over the entries in a keymap. Keyword `key-seq' causes | |
| 943 recursive mapping over prefix keymaps occurring in the keymap, with VAR | |
| 944 getting the built-up sequence (a vector). Otherwise, mapping does not | |
| 945 occur recursively. `key-code' and `key-seq' refer to what is bound | |
| 946 (second argument of `define-key'), and `key-binding' what it's bound to | |
| 947 (third argument of `define-key'). | |
| 948 | |
| 949 as VAR ... | |
| 950 `as' is a synonym for `for'. | |
| 951 | |
| 952 and VAR ... | |
| 953 `and' clauses have the same syntax as `for' clauses except that the | |
| 954 variables in the clause are bound in parallel with a preceding | |
| 955 `and'/`for' clause instead of in series. | |
| 956 | |
| 957 with VAR = INIT | |
| 958 Set VAR to INIT once, before doing any iterations. | |
| 959 | |
| 960 repeat NUM | |
| 961 Exit the loop if more than NUM iterations have occurred. | |
| 962 | |
| 963 while COND | |
| 964 Exit the loop if COND isn't true. | |
| 965 | |
| 966 until COND | |
| 967 Exit the loop if COND is true. | |
| 968 | |
| 969 collect EXPR [into VAR] | |
| 970 Push EXPR onto the end of a list of values -- stored either in VAR or a | |
| 971 temporary variable that will be returned as the return value of the | |
| 972 loop if it terminates through an exit condition or a call to | |
| 973 `loop-finish'. | |
| 974 | |
| 975 append EXPR [into VAR] | |
| 976 Append EXPR (a list) onto the end of a list of values, like `collect'. | |

| 994 Add EXPR to a value, like `collect'. | |
| 995 | |
| 996 count EXPR [into VAR] | |
| 997 If EXPR is true, increment a value by 1, like `collect'. | |
| 998 | |
| 999 maximize EXPR [into VAR] | |

| 2060 "(defsetf NAME FUNC): define a `setf' method. | |
| 2061 This macro is an easy-to-use substitute for `define-setf-method' that works | |
| 2062 well for simple place forms. In the simple `defsetf' form, `setf's of | |
| 2063 the form (setf (NAME ARGS...) VAL) are transformed to function or macro | |
| 2064 calls of the form (FUNC ARGS... VAL). Example: (defsetf aref aset). | |
| 2065 Alternate form: (defsetf NAME ARGLIST (STORE) BODY...). | |
| 2066 Here, the above `setf' call is expanded by binding the argument forms ARGS | |
| 2067 according to ARGLIST, binding the value form VAL to STORE, then executing | |
| 2068 BODY, which must return a Lisp form that does the necessary `setf' operation. | |
| 2069 Actually, ARGLIST and STORE may be bound to temporary variables which are | |
| 2070 introduced automatically to preserve proper execution order of the arguments. | |
| 2071 Example: (defsetf nth (n x) (v) (list 'setcar (list 'nthcdr n x) v))." | |

3177 "Define a compiler-only macro. |
| 428 | 3178 This is like `defmacro', but macro expansion occurs only if the call to |
| 3179 FUNC is compiled (i.e., not interpreted). Compiler macros should be used | |
| 3180 for optimizing the way calls to FUNC are compiled; the form returned by | |
| 3181 BODY should do the same thing as a call to the normal function called | |
| 3182 FUNC, though possibly more efficiently. Note that, like regular macros, | |
| 3183 compiler macros are expanded repeatedly until no further expansions are | |
| 3184 possible. Unlike regular macros, BODY can decide to \"punt\" and leave the | |
| 3185 original function call alone by declaring an initial `&whole foo' parameter | |
