fix so that CL docstrings (with &key, etc.) handled properly
-------------------- ChangeLog entries follow: --------------------
lisp/ChangeLog addition:
2010-02-23 Ben Wing <ben@xemacs.org>
* autoload.el:
* autoload.el (make-autoload):
* cl-macs.el (cl-function-arglist):
* cl-macs.el (cl-transform-lambda):
Don't add argument list with the tag "Common Lisp lambda list:";
instead add in "standard" form using "arguments:" and omitting the
function name. Add an arg to `cl-function-arglist' to omit the
name and use it in autoload.el instead of just hacking it off.
* help.el:
* help.el (function-arglist):
* help.el (function-documentation-1): New.
Extract out common code to recognize and/or strip the arglist from
documentation into `function-documentation-1'. Use in
`function-arglist' and `function-documentation'. Modify
`function-arglist' so it looks for the `arguments: ' stuff in all
doc strings, not just subrs/autoloads, so that CL functions get
recognized properly. Change the regexp used to match "arguments: "
specs to allow nested parens inside the arg list (happens when you
have a default value specified in a CL arglist).

| 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. | |

| 189 variables, they can be lists of the form (VAR [INITFORM [SVAR]]); when | |
| 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 | |
| 195 -- &key specifies keyword arguments. The format of each argument is | |
| 196 VAR || ( { VAR || (KEYWORD VAR) } [INITFORM [SVAR]]) -- #### document me. | |
| 197 | |
| 198 -- &allow-other-keys means that if other keyword arguments are given that are | |
| 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 | |
| 204 format of `let'/`let*' bindings. | |

| 212 "(defmacro* NAME ARGLIST [DOCSTRING] BODY...): define NAME as a macro. | |
| 213 Like normal `defmacro', except ARGLIST allows full Common Lisp conventions, | |
| 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 This is similar to `let' but it does \"destructuring\", in that it matches | |
| 532 the structure of ARGS to the structure of EXPR and binds corresponding | |
| 533 arguments in ARGS to their values in EXPR. The format of ARGS, and the | |
| 534 way the destructuring works, is exactly like the destructuring that occurs | |
| 535 in `defmacro*'; see that for more information. | |
| 536 | |
| 537 An alternative means of destructuring is using the `loop' macro. `loop' | |
| 538 gives practical examples of destructuring. `defmacro*' describes the | |
| 539 differences between loop and macro-style destructuring. | |
| 540 | |
| 541 You can rewrite a call to (destructuring-bind ARGS EXPR &rest BODY) using | |

| 543 | |
| 544 (loop for ARGS = EXPR | |
| 545 return (progn BODY)) | |

| 777 (defmacro loop (&rest args) | |
| 778 "(loop CLAUSE...): The Common Lisp `loop' macro. | |
| 800 | 779 |
| 780 The loop macro consists of a series of clauses, which do things like | |
| 781 iterate variables, set conditions for exiting the loop, accumulating values | |
| 782 to be returned as the return value of the loop, and executing arbitrary | |
| 2297 | 783 blocks of code. Each clause is processed in turn, and the loop executes its |
| 800 | 784 body repeatedly until an exit condition is hit. |
| 785 | |
| 786 It's important to understand that loop clauses such as `for' and `while', | |
| 787 which look like loop-establishing constructs, don't actually *establish* a | |
| 788 loop\; the looping is established by the `loop' clause itself, which will | |
| 789 repeatedly process its body until told to stop. `while' merely establishes | |
| 790 a condition which, when true, causes the loop to finish, and `for' sets a | |
| 791 variable to different values on each iteration (e.g. successive elements of | |
| 792 a list) and sets an exit condition when there are no more values. This | |
| 793 means, for example, that if two `for' clauses appear, you don't get two | |
| 794 nested loops, but instead two variables that are stepped in parallel, and | |
| 795 two exit conditions, either of which, if triggered, will cause the loop to | |
| 796 end. Similarly for a loop with a `for' and a `while' clause. For example: | |
| 797 | |
| 798 \(loop | |
| 799 for x in list | |
| 800 while x | |
| 801 do ...) | |
| 802 | |
| 803 In each successive iteration, X is set to the next element of the list. If | |
| 804 there are no more elements, or if any element is nil (the `while' clause), | |
| 805 the loop exits. Otherwise, the block of code following `do' is executed.) | |
| 806 | |
| 807 This example also shows that some clauses establish variable bindings -- | |
| 808 essentially like a `let' binding -- and that following clauses can | |
| 809 reference these variables. Furthermore, the entire loop is surrounded by a | |
| 810 block named nil (unless the `named' clause is given), so you can return | |
| 811 from the loop using the macro `return'. (The other way to exit the loop is | |
| 812 through the macro `loop-finish'. The difference is that some loop clauses | |
| 813 establish or accumulate a value to be returned, and `loop-finish' returns | |
| 814 this. `return', however, can only return an explicitly-specified value. | |
| 815 NOTE CAREFULLY: There is a loop clause called `return' as well as a | |
| 816 standard Lisp macro called `return'. Normally they work similarly\; but if | |
| 817 you give the loop a name with `named', you will need to use the macro | |
| 818 `return-from'.) | |
| 819 | |
| 820 Another extremely useful feature of loops is called \"destructuring\". If, | |
| 821 in place of VAR, a list (possibly dotted, possibly a tree of arbitary | |
| 822 complexity) is given, the value to be assigned is assumed to have a similar | |
| 823 structure to the list given, and variables in the list will be matched up | |
| 824 with corresponding elements in the structure. For example: | |
| 825 | |
| 826 \(loop | |
| 827 for (x y) in '((foo 1) (bar 2) (baz 3)) | |
| 828 do (puthash x y some-hash-table)) | |
| 829 | |
| 830 will add three elements to a hash table, mapping foo -> 1, bar -> 2, and | |
| 831 baz -> 3. As other examples, you can conveniently process alists using | |
| 832 | |
| 833 \(loop for (x . y) in alist do ...) | |
| 834 | |
| 835 and plists using | |
| 836 | |
| 837 \(loop for (x y) on plist by #'cddr do ...) | |
| 838 | |
| 839 Destructuring is forgiving in that mismatches in the number of elements on | |
| 840 either size will be handled gracefully, either by ignoring or initializing | |
| 1123 | 841 to nil. Destructuring is extremely powerful, and is probably the single |
| 842 most useful feature of `loop'. | |
| 843 | |
| 844 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, | |
| 845 | |
| 846 \(loop for x being the hash-key in table using (hash-value y) | |
| 847 collect (cons x y)) | |
| 848 | |
| 849 converts hash-table TABLE to an alist. (What `collect' actually does is | |
| 850 push its value onto the end of an internal list and establish this list as | |
| 851 the default return value of the loop. See below for more information.) | |
| 852 | |
| 853 An example of in-place modification is | |
| 854 | |
| 855 \(setq foo '(1 3 5)) | |
| 856 \(loop for x in-ref foo do | |
| 857 (setf x (* x x))) | |
| 858 | |
| 859 after which foo will contain '(1 9 25). | |
| 800 | 860 |
| 861 If you don't understand how a particular loop clause works, create an | |
| 862 example and use `macroexpand-sexp' to expand the macro. | |
| 863 | |
| 428 | 864 Valid clauses are: |
| 800 | 865 |
| 866 \(NOTE: Keywords in lowercase\; slashes separate different possibilities | |
| 867 for keywords, some of which are synonymous\; brackets indicate optional | |
| 868 parts of the clause. In all of the clauses with `being', the word `being', | |
| 869 the words `each' or `the', and the difference between singular and plural | |
| 870 keywords are all just syntactic sugar. Stylistically, you should write | |
| 871 either `being each foo' or `being the foos'.) | |
| 872 | |
| 873 for VAR from/upfrom/downfrom NUM1 to/upto/downto/above/below NUM2 [by NUMSTEP] | |
| 874 Step VAR across numbers. `upfrom', `upto', and `below' explicitly | |
| 875 indicate upward stepping\; `downfrom', `downto', and `above' explicitly | |
| 876 indicate downward stepping. (If none of these is given, the default is | |
| 877 upward.) `to', `upto', and `downto' cause stepping to include NUM2 as | |
| 878 the last iteration, while `above' and `below' stop just before reaching | |
| 879 NUM2. `by' can be given to indicate a stepping increment other than 1. | |
| 880 | |
| 881 for VAR in LIST [by FUNC] | |
| 882 Step VAR over elements of a LIST. FUNC specifies how to get successive | |
| 883 sublists and defaults to `cdr'. | |
| 884 | |
| 885 for VAR on LIST [by FUNC] | |
| 886 Step VAR over tails of a LIST. FUNC specifies how to get successive | |
| 887 sublists and defaults to `cdr'. | |
| 888 | |
| 889 for VAR in-ref LIST [by FUNC] | |
| 890 Step VAR over elements of a LIST, like `for ... in', except the VAR is | |
| 891 bound using `symbol-macrolet' instead of `let'. In essence, VAR is set | |
| 892 to a \"reference\" to the list element instead of the element itself\; | |
| 893 this us, you can destructively modify the list using `setf' on VAR, and | |
| 894 any changes to the list will \"magically\" reflect themselves in | |
| 895 subsequent uses of VAR. | |
| 896 | |
| 897 for VAR = INIT [then EXPR] | |
| 898 Set VAR on each iteration of the loop. If only INIT is given, use it | |
| 899 on each iteration. Otherwise, use INIT on the first iteration and EXPR | |
| 900 on subsequent ones. | |
| 901 | |
| 902 for VAR across/across-ref ARRAY | |
| 903 Step VAR across a sequence other than a list (string, vector, bit | |
| 904 vector). If `across-ref' is given, VAR is bound using | |
| 905 `symbol-macrolet' instead of `let' -- see above. | |
| 906 | |
| 907 for VAR being each/the element/elements in/of/in-ref/of-ref SEQUENCE [using (index INDEX-VAR)] | |
| 908 Step VAR across any sequence. A variable can be specified with a | |
| 909 `using' phrase to receive the index, starting at 0. If `in-ref' or | |
| 910 `of-ref' is given, VAR is bound using `symbol-macrolet' instead of | |
| 911 `let' -- see above. | |
| 912 | |
| 913 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
| 914 | |
| 915 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
| 916 Map VAR over a hash table. The various keywords are synonymous except | |
| 917 those that distinguish between keys and values. The `using' phrase is | |
| 918 optional and allows both key and value to be bound. | |
| 919 | |
| 920 for VAR being each/the symbol/present-symbol/external-symbol/symbols/present-symbols/external-symbols in/of OBARRAY | |
| 921 Map VAR over the symbols in an obarray. All symbol keywords are | |
| 922 currently synonymous. | |
| 923 | |
| 924 for VAR being each/the extent/extents [in/of BUFFER-OR-STRING] [from POS] [to POS] | |
| 925 Map VAR over the extents in a buffer or string, defaulting to the | |
| 926 current buffer, the beginning and the end, respectively. | |
| 927 | |
| 928 for VAR being each/the interval/intervals [in/of BUFFER-OR-STRING] [property PROPERTY] [from POS] [to POS] | |
| 929 Map VAR over the intervals without property change in a buffer or | |
| 930 string, defaulting to the current buffer, the beginning and the end, | |
| 931 respectively. If PROPERTY is given, iteration occurs using | |
| 932 `next-single-property-change'\; otherwise, using | |
| 933 `next-property-change'. | |
| 934 | |
| 935 for VAR being each/the window/windows [in/of FRAME] | |
| 936 Step VAR over the windows in FRAME, defaulting to the selected frame. | |
| 937 | |
| 938 for VAR being each/the frame/frames | |
| 939 Step VAR over all frames. | |
| 940 | |
| 941 for VAR being each/the buffer/buffers [by FUNC] | |
| 942 Step VAR over all buffers. This is actually equivalent to | |
| 943 `for VAR in (buffer-list) [by FUNC]'. | |
| 944 | |
| 945 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)] | |
| 946 Map VAR over the entries in a keymap. Keyword `key-seq' causes | |
| 947 recursive mapping over prefix keymaps occurring in the keymap, with VAR | |
| 948 getting the built-up sequence (a vector). Otherwise, mapping does not | |
| 949 occur recursively. `key-code' and `key-seq' refer to what is bound | |
| 950 (second argument of `define-key'), and `key-binding' what it's bound to | |
| 951 (third argument of `define-key'). | |
| 952 | |
| 953 as VAR ... | |
| 954 `as' is a synonym for `for'. | |
| 955 | |
| 956 and VAR ... | |
| 957 `and' clauses have the same syntax as `for' clauses except that the | |
| 958 variables in the clause are bound in parallel with a preceding | |
| 959 `and'/`for' clause instead of in series. | |
| 960 | |
| 961 with VAR = INIT | |
| 962 Set VAR to INIT once, before doing any iterations. | |
| 963 | |
| 964 repeat NUM | |
| 965 Exit the loop if more than NUM iterations have occurred. | |
| 966 | |
| 967 while COND | |
| 968 Exit the loop if COND isn't true. | |
| 969 | |
| 970 until COND | |
| 971 Exit the loop if COND is true. | |
| 972 | |
| 973 collect EXPR [into VAR] | |
| 974 Push EXPR onto the end of a list of values -- stored either in VAR or a | |
| 975 temporary variable that will be returned as the return value of the | |
| 976 loop if it terminates through an exit condition or a call to | |
| 977 `loop-finish'. | |
| 978 | |
| 979 append EXPR [into VAR] | |
| 980 Append EXPR (a list) onto the end of a list of values, like `collect'. | |
| 981 | |
| 982 nconc EXPR [into VAR] | |
| 983 Nconc EXPR (a list) onto the end of a list of values, like `collect'. | |
| 984 | |
| 985 concat EXPR [into VAR] | |
| 986 Concatenate EXPR (a string) onto the end of a string of values, like | |
| 987 `collect'. | |
| 988 | |
| 989 vconcat EXPR [into VAR] | |
| 990 Concatenate EXPR (a vector) onto the end of a vector of values, like | |
| 991 `collect'. | |
| 992 | |
| 993 bvconcat EXPR [into VAR] | |
| 994 Concatenate EXPR (a bit vector) onto the end of a bit vector of values, | |
| 995 like `collect'. | |
| 996 | |
| 997 sum EXPR [into VAR] | |
| 998 Add EXPR to a value, like `collect'. | |
| 999 | |
| 1000 count EXPR [into VAR] | |
| 1001 If EXPR is true, increment a value by 1, like `collect'. | |
| 1002 | |
| 1003 maximize EXPR [into VAR] | |
| 1004 IF EXPR is greater than a value, replace the value with EXPR, like | |
| 1005 `collect'. | |
| 1006 | |
| 1007 minimize EXPR [into VAR] | |
| 1008 IF EXPR is less than a value, replace the value with EXPR, like | |
| 1009 `collect'. | |
| 1010 | |
| 1011 always COND | |
| 1012 If COND is true, continue the loop and set the loop return value (the | |
| 1013 same value that's manipulated by `collect' and friends and is returned | |
| 1014 by a normal loop exit or an exit using `loop-finish') to t\; otherwise, | |
| 1015 exit the loop and return nil. The effect is to determine and return | |
| 1016 whether a condition is true \"always\" (all iterations of the loop). | |
| 1017 | |
| 1018 never COND | |
| 1019 If COND is false, continue the loop and set the loop return value (like | |
| 1020 `always') to t\; otherwise, exit the loop and return nil. The effect | |
| 1021 is to determine and return whether a condition is \"never\" true (all | |
| 1022 iterations of the loop). | |
| 1023 | |
| 1024 thereis COND | |
| 1025 If COND is true, exit the loop and return COND. | |
| 1026 | |
| 1027 if/when COND CLAUSE [and CLAUSE]... else CLAUSE [and CLAUSE...] | |
| 1028 If COND is true, execute the directly following clause(s)\; otherwise, | |
| 1029 execute the clauses following `else'. | |
| 1030 | |
| 1031 unless COND CLAUSE [and CLAUSE]... else CLAUSE [and CLAUSE...] | |
| 1032 If COND is false, execute the directly following clause(s)\; otherwise, execute the clauses following `else'. | |
| 1033 | |
| 1034 do EXPRS... | |
| 1035 Execute the expressions (any Lisp forms). | |
| 1036 | |
| 1037 initially EXPRS... | |
| 1038 Execute EXPR once, before doing any iterations, and after values have | |
| 1039 been set using `with'. | |
| 1040 | |
| 1041 finally EXPRS... | |
| 1042 Execute EXPR once, directly before the loop terminates. This will not | |
| 1043 be executed if the loop terminates prematurely as a result of `always', | |
| 1044 `never', `thereis', or `return'. | |
| 1045 | |
| 1046 return EXPR | |
| 1047 Exit from the loop and return EXPR. | |
| 1048 | |
| 1049 finally return EXPR | |
| 1050 Specify the value to be returned when the loop exits. (Unlike `return', | |
| 1051 this doesn't cause the loop to immediately exit\; it will exit whenever | |
| 1052 it normally would have.) This takes precedence over a return value | |
| 1053 specified with `collect' and friends or `always' and friends. | |
| 1054 | |
| 1055 named NAME | |
| 1056 Specify the name for block surrounding the loop, in place of nil. | |
| 1057 (See `block'.) | |

| 2019 "(defsetf NAME FUNC): define a `setf' method. | |
| 2020 This macro is an easy-to-use substitute for `define-setf-method' that works | |
| 2021 well for simple place forms. In the simple `defsetf' form, `setf's of | |
| 2022 the form (setf (NAME ARGS...) VAL) are transformed to function or macro | |
| 2023 calls of the form (FUNC ARGS... VAL). Example: (defsetf aref aset). | |
| 2024 Alternate form: (defsetf NAME ARGLIST (STORE) BODY...). | |
| 2025 Here, the above `setf' call is expanded by binding the argument forms ARGS | |
| 2026 according to ARGLIST, binding the value form VAL to STORE, then executing | |
| 2027 BODY, which must return a Lisp form that does the necessary `setf' operation. | |
| 2028 Actually, ARGLIST and STORE may be bound to temporary variables which are | |
| 2029 introduced automatically to preserve proper execution order of the arguments. | |
| 2030 Example: (defsetf nth (n x) (v) (list 'setcar (list 'nthcdr n x) v))." | |
