annotate lisp/cl-macs.el @ 4792:95b04754ea8c
Make #'equalp more compatible with CL; add a compiler macro, test & doc it.
lisp/ChangeLog addition:
2009-11-08 Aidan Kehoe <kehoea@parhasard.net>
* cl-extra.el (cl-string-vector-equalp)
(cl-bit-vector-vector-equalp, cl-vector-array-equalp)
(cl-hash-table-contents-equalp): New functions, to implement
equalp treating arrays with identical contents as equivalent, as
specified by Common Lisp.
(equalp): Revise this function to implement array equivalence,
and the hash-table equalp behaviour specified by CL.
* cl-macs.el (equalp): Add a compiler macro for this function,
used when one of the arguments is constant, and as such, its type
is known at compile time.
man/ChangeLog addition:
2009-11-08 Aidan Kehoe <kehoea@parhasard.net>
* lispref/objects.texi (Equality Predicates):
Document #'equalp here, as well as #'equal and #'eq.
tests/ChangeLog addition:
2009-12-31 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test much of the functionality of equalp; add a pointer to Paul
Dietz' ANSI test suite for this function, converted to Emacs
Lisp. Not including the tests themselves in XEmacs because who
owns the copyright on the files is unclear and the GCL people
didn't respond to my queries.

| 30 | |
| 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. | |
| 37 ;; | |
| 38 ;; Bug reports, comments, and suggestions are welcome! | |
| 39 | |
| 40 ;; This file contains the portions of the Common Lisp extensions | |
| 41 ;; package which should be autoloaded, but need only be present | |
| 42 ;; if the compiler or interpreter is used---this file is not | |
| 43 ;; necessary for executing compiled code. | |

| 190 no argument is available for VAR, INITFORM is evaluated (or nil, if | |
| 191 INITFORM is omitted) and stored as VAR's value, and SVAR is bound to t. | |
| 192 If an arguent is available for VAR, and INITFORM is unused, SVAR is | |
| 193 bound to nil. | |
| 194 | |

| 199 not specifically list in the arg list, they are allowed, rather than an | |
| 200 error being signalled. They can be retrieved with an &rest form. | |
| 201 | |
| 202 -- &aux specifies extra bindings, exactly like a `let*' enclosing the body. | |
| 203 The format of each binding is VAR || (VAR [INITFORM]) -- exactly like the | |

| 872 | 214 and BODY is implicitly surrounded by (block NAME ...). |
| 215 | |
| 216 \"Full Common Lisp conventions\" means that: | |
| 217 | |
| 218 -- The lambda-list keywords &optional, &rest, &key, &allow-other-keys, and | |
| 219 &aux are allowed, as in `defun*'. | |
| 220 | |
| 221 -- Three additional lambda-list keywords are allowed: &body, &whole, and | |
| 222 &environment. #### Document me. | |
| 223 | |
| 224 -- The macro arg list syntax allows for \"destructuring\" -- see also | |
| 225 `destructuring-bind', which destructures exactly like `defmacro*', and | |
| 226 `loop', which does a rather different way of destructuring. Anywhere | |
| 227 that a simple argument may appear, and (if following a lambda-list | |
| 228 keyword) a list may not normally appear, an embedded lambda list can be | |
| 229 substituted. (The format of the embedded lambda list is exactly the | |
| 230 same as for a top-level list except that &environment is not allowed.) | |
| 231 When matching this lambda list against a caller-specified argument, that | |
| 232 argument is treated as a list and normal lambda-list processing occurs, | |
| 233 just as if the entire operation were happening at top level. | |
| 234 Furthermore, any lambda list, embedded or top-level, can be dotted at its | |
| 235 end, and this will cause matching with an appropriate dotted list given | |
| 236 as an argument. | |
| 237 | |
| 238 See `loop' for practical examples of destructuring, but | |
| 239 keep in mind that `loop' destructuring is somewhat different from macro | |
| 240 destructuring in that | |
| 241 | |
| 242 (a) Macro destructuring has extra features in the various lambda-list | |
| 243 keywords, allowing for special processing of a list other than just | |
| 244 simple matching. | |
| 245 (b) Macro destructuring is strict, in that an error is signalled if the | |
| 246 actual structure does not match the expected structure. On the | |
| 247 other hand, loop destructuring is lax -- extra arguments in a list | |
| 248 are ignored, not enough arguments cause the remaining parameters to | |
| 249 receive a value of nil, etc. | |

| 531 An alternative means of destructuring is using the `loop' macro. `loop' | |
| 532 gives practical examples of destructuring. `defmacro*' describes the | |

| 771 (defmacro loop (&rest args) | |
| 772 "(loop CLAUSE...): The Common Lisp `loop' macro. | |
| 800 | 773 |
| 774 The loop macro consists of a series of clauses, which do things like | |
| 775 iterate variables, set conditions for exiting the loop, accumulating values | |
| 776 to be returned as the return value of the loop, and executing arbitrary | |
| 2297 | 777 blocks of code. Each clause is processed in turn, and the loop executes its |
| 800 | 778 body repeatedly until an exit condition is hit. |
| 779 | |
| 780 It's important to understand that loop clauses such as `for' and `while', | |
| 781 which look like loop-establishing constructs, don't actually *establish* a | |
| 782 loop\; the looping is established by the `loop' clause itself, which will | |
| 783 repeatedly process its body until told to stop. `while' merely establishes | |
| 784 a condition which, when true, causes the loop to finish, and `for' sets a | |
| 785 variable to different values on each iteration (e.g. successive elements of | |
| 786 a list) and sets an exit condition when there are no more values. This | |
| 787 means, for example, that if two `for' clauses appear, you don't get two | |
| 788 nested loops, but instead two variables that are stepped in parallel, and | |
| 789 two exit conditions, either of which, if triggered, will cause the loop to | |
| 790 end. Similarly for a loop with a `for' and a `while' clause. For example: | |
| 791 | |
| 792 \(loop | |
| 793 for x in list | |
| 794 while x | |
| 795 do ...) | |
| 796 | |
| 797 In each successive iteration, X is set to the next element of the list. If | |
| 798 there are no more elements, or if any element is nil (the `while' clause), | |
| 799 the loop exits. Otherwise, the block of code following `do' is executed.) | |
| 800 | |
| 801 This example also shows that some clauses establish variable bindings -- | |
| 802 essentially like a `let' binding -- and that following clauses can | |
| 803 reference these variables. Furthermore, the entire loop is surrounded by a | |
| 804 block named nil (unless the `named' clause is given), so you can return | |
| 805 from the loop using the macro `return'. (The other way to exit the loop is | |
| 806 through the macro `loop-finish'. The difference is that some loop clauses | |
| 807 establish or accumulate a value to be returned, and `loop-finish' returns | |
| 808 this. `return', however, can only return an explicitly-specified value. | |
| 809 NOTE CAREFULLY: There is a loop clause called `return' as well as a | |
| 810 standard Lisp macro called `return'. Normally they work similarly\; but if | |
| 811 you give the loop a name with `named', you will need to use the macro | |
| 812 `return-from'.) | |
| 813 | |
| 814 Another extremely useful feature of loops is called \"destructuring\". If, | |
| 815 in place of VAR, a list (possibly dotted, possibly a tree of arbitary | |
| 816 complexity) is given, the value to be assigned is assumed to have a similar | |
| 817 structure to the list given, and variables in the list will be matched up | |
| 818 with corresponding elements in the structure. For example: | |
| 819 | |
| 820 \(loop | |
| 821 for (x y) in '((foo 1) (bar 2) (baz 3)) | |
| 822 do (puthash x y some-hash-table)) | |
| 823 | |
| 824 will add three elements to a hash table, mapping foo -> 1, bar -> 2, and | |
| 825 baz -> 3. As other examples, you can conveniently process alists using | |
| 826 | |
| 827 \(loop for (x . y) in alist do ...) | |
| 828 | |
| 829 and plists using | |
| 830 | |
| 831 \(loop for (x y) on plist by #'cddr do ...) | |
| 832 | |
| 833 Destructuring is forgiving in that mismatches in the number of elements on | |
| 834 either size will be handled gracefully, either by ignoring or initializing | |
| 1123 | 835 to nil. Destructuring is extremely powerful, and is probably the single |
| 836 most useful feature of `loop'. | |
| 837 | |
| 838 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, | |
| 839 | |
| 840 \(loop for x being the hash-key in table using (hash-value y) | |
| 841 collect (cons x y)) | |
| 842 | |
| 843 converts hash-table TABLE to an alist. (What `collect' actually does is | |
| 844 push its value onto the end of an internal list and establish this list as | |
| 845 the default return value of the loop. See below for more information.) | |
| 846 | |
| 847 An example of in-place modification is | |
| 848 | |
| 849 \(setq foo '(1 3 5)) | |
| 850 \(loop for x in-ref foo do | |
| 851 (setf x (* x x))) | |
| 852 | |
| 853 after which foo will contain '(1 9 25). | |
| 800 | 854 |
| 855 If you don't understand how a particular loop clause works, create an | |
| 856 example and use `macroexpand-sexp' to expand the macro. | |
| 857 | |
| 428 | 858 Valid clauses are: |
| 800 | 859 |
| 860 \(NOTE: Keywords in lowercase\; slashes separate different possibilities | |
| 861 for keywords, some of which are synonymous\; brackets indicate optional | |
| 862 parts of the clause. In all of the clauses with `being', the word `being', | |
| 863 the words `each' or `the', and the difference between singular and plural | |
| 864 keywords are all just syntactic sugar. Stylistically, you should write | |
| 865 either `being each foo' or `being the foos'.) | |
| 866 | |
| 867 for VAR from/upfrom/downfrom NUM1 to/upto/downto/above/below NUM2 [by NUMSTEP] | |
| 868 Step VAR across numbers. `upfrom', `upto', and `below' explicitly | |
| 869 indicate upward stepping\; `downfrom', `downto', and `above' explicitly | |
| 870 indicate downward stepping. (If none of these is given, the default is | |
| 871 upward.) `to', `upto', and `downto' cause stepping to include NUM2 as | |
| 872 the last iteration, while `above' and `below' stop just before reaching | |
| 873 NUM2. `by' can be given to indicate a stepping increment other than 1. | |
| 874 | |
| 875 for VAR in LIST [by FUNC] | |
| 876 Step VAR over elements of a LIST. FUNC specifies how to get successive | |
| 877 sublists and defaults to `cdr'. | |
| 878 | |
| 879 for VAR on LIST [by FUNC] | |
| 880 Step VAR over tails of a LIST. FUNC specifies how to get successive | |
| 881 sublists and defaults to `cdr'. | |
| 882 | |
| 883 for VAR in-ref LIST [by FUNC] | |
| 884 Step VAR over elements of a LIST, like `for ... in', except the VAR is | |
| 885 bound using `symbol-macrolet' instead of `let'. In essence, VAR is set | |
| 886 to a \"reference\" to the list element instead of the element itself\; | |
| 887 this us, you can destructively modify the list using `setf' on VAR, and | |
| 888 any changes to the list will \"magically\" reflect themselves in | |
| 889 subsequent uses of VAR. | |
| 890 | |
| 891 for VAR = INIT [then EXPR] | |
| 892 Set VAR on each iteration of the loop. If only INIT is given, use it | |
| 893 on each iteration. Otherwise, use INIT on the first iteration and EXPR | |
| 894 on subsequent ones. | |
| 895 | |
| 896 for VAR across/across-ref ARRAY | |
| 897 Step VAR across a sequence other than a list (string, vector, bit | |
| 898 vector). If `across-ref' is given, VAR is bound using | |
| 899 `symbol-macrolet' instead of `let' -- see above. | |
| 900 | |
| 901 for VAR being each/the element/elements in/of/in-ref/of-ref SEQUENCE [using (index INDEX-VAR)] | |
| 902 Step VAR across any sequence. A variable can be specified with a | |
| 903 `using' phrase to receive the index, starting at 0. If `in-ref' or | |
| 904 `of-ref' is given, VAR is bound using `symbol-macrolet' instead of | |
| 905 `let' -- see above. | |
| 906 | |
| 907 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
| 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 Map VAR over a hash table. The various keywords are synonymous except | |
| 911 those that distinguish between keys and values. The `using' phrase is | |
| 912 optional and allows both key and value to be bound. | |
| 913 | |
| 914 for VAR being each/the symbol/present-symbol/external-symbol/symbols/present-symbols/external-symbols in/of OBARRAY | |
| 915 Map VAR over the symbols in an obarray. All symbol keywords are | |
| 916 currently synonymous. | |
| 917 | |
| 918 for VAR being each/the extent/extents [in/of BUFFER-OR-STRING] [from POS] [to POS] | |
| 919 Map VAR over the extents in a buffer or string, defaulting to the | |
| 920 current buffer, the beginning and the end, respectively. | |
| 921 | |
| 922 for VAR being each/the interval/intervals [in/of BUFFER-OR-STRING] [property PROPERTY] [from POS] [to POS] | |
| 923 Map VAR over the intervals without property change in a buffer or | |
| 924 string, defaulting to the current buffer, the beginning and the end, | |
| 925 respectively. If PROPERTY is given, iteration occurs using | |
| 926 `next-single-property-change'\; otherwise, using | |
| 927 `next-property-change'. | |
| 928 | |
| 929 for VAR being each/the window/windows [in/of FRAME] | |
| 930 Step VAR over the windows in FRAME, defaulting to the selected frame. | |
| 931 | |
| 932 for VAR being each/the frame/frames | |
| 933 Step VAR over all frames. | |
| 934 | |
| 935 for VAR being each/the buffer/buffers [by FUNC] | |
| 936 Step VAR over all buffers. This is actually equivalent to | |
| 937 `for VAR in (buffer-list) [by FUNC]'. | |
| 938 | |
| 939 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)] | |
| 940 Map VAR over the entries in a keymap. Keyword `key-seq' causes | |
| 941 recursive mapping over prefix keymaps occurring in the keymap, with VAR | |
| 942 getting the built-up sequence (a vector). Otherwise, mapping does not | |
| 943 occur recursively. `key-code' and `key-seq' refer to what is bound | |
| 944 (second argument of `define-key'), and `key-binding' what it's bound to | |
| 945 (third argument of `define-key'). | |
| 946 | |
| 947 as VAR ... | |
| 948 `as' is a synonym for `for'. | |
| 949 | |
| 950 and VAR ... | |
| 951 `and' clauses have the same syntax as `for' clauses except that the | |
| 952 variables in the clause are bound in parallel with a preceding | |
| 953 `and'/`for' clause instead of in series. | |
| 954 | |
| 955 with VAR = INIT | |
| 956 Set VAR to INIT once, before doing any iterations. | |
| 957 | |
| 958 repeat NUM | |
| 959 Exit the loop if more than NUM iterations have occurred. | |
| 960 | |
| 961 while COND | |
| 962 Exit the loop if COND isn't true. | |
| 963 | |
| 964 until COND | |
| 965 Exit the loop if COND is true. | |
| 966 | |
| 967 collect EXPR [into VAR] | |
| 968 Push EXPR onto the end of a list of values -- stored either in VAR or a | |
| 969 temporary variable that will be returned as the return value of the | |
| 970 loop if it terminates through an exit condition or a call to | |
| 971 `loop-finish'. | |
| 972 | |

| 1010 whether a condition is true \"always\" (all iterations of the loop). | |

| 1038 `never', `thereis', or `return'. | |

| 1044 Specify the value to be returned when the loop exits. (Unlike `return', | |
| 1045 this doesn't cause the loop to immediately exit\; it will exit whenever | |
| 1046 it normally would have.) This takes precedence over a return value | |
| 1047 specified with `collect' and friends or `always' and friends. | |
| 1048 | |

| 2013 "(defsetf NAME FUNC): define a `setf' method. | |
| 2014 This macro is an easy-to-use substitute for `define-setf-method' that works | |
| 2015 well for simple place forms. In the simple `defsetf' form, `setf's of | |
| 2016 the form (setf (NAME ARGS...) VAL) are transformed to function or macro | |
| 2017 calls of the form (FUNC ARGS... VAL). Example: (defsetf aref aset). | |
| 2018 Alternate form: (defsetf NAME ARGLIST (STORE) BODY...). | |
| 2019 Here, the above `setf' call is expanded by binding the argument forms ARGS | |
| 2020 according to ARGLIST, binding the value form VAL to STORE, then executing | |
| 2021 BODY, which must return a Lisp form that does the necessary `setf' operation. | |
| 2022 Actually, ARGLIST and STORE may be bound to temporary variables which are | |
| 2023 introduced automatically to preserve proper execution order of the arguments. | |
| 2024 Example: (defsetf nth (n x) (v) (list 'setcar (list 'nthcdr n x) v))." | |

3123 "Define a compiler-only macro. |
| 428 | 3124 This is like `defmacro', but macro expansion occurs only if the call to |
| 3125 FUNC is compiled (i.e., not interpreted). Compiler macros should be used | |
| 3126 for optimizing the way calls to FUNC are compiled; the form returned by | |
| 3127 BODY should do the same thing as a call to the normal function called | |
| 3128 FUNC, though possibly more efficiently. Note that, like regular macros, | |
| 3129 compiler macros are expanded repeatedly until no further expansions are | |
| 3130 possible. Unlike regular macros, BODY can decide to \"punt\" and leave the | |
