Further frame-geometry cleanups
-------------------- ChangeLog entries follow: --------------------
man/ChangeLog addition:
2010-03-03 Ben Wing <ben@xemacs.org>
* internals/internals.texi (Intro to Window and Frame Geometry):
* internals/internals.texi (The Paned Area):
* internals/internals.texi (The Displayable Area):
Update to make note of e.g. the fact that the bottom gutter is
actually above the minibuffer.
src/ChangeLog addition:
2010-03-03 Ben Wing <ben@xemacs.org>
* emacs.c:
* emacs.c (assert_equal_failed):
* lisp.h:
* lisp.h (assert_equal):
New fun assert_equal, asserting that two values == each other, and
printing out both values upon failure.
* frame-gtk.c (gtk_initialize_frame_size):
* frame-impl.h:
* frame-impl.h (FRAME_TOP_INTERNAL_BORDER_START):
* frame-impl.h (FRAME_BOTTOM_INTERNAL_BORDER_START):
* frame-impl.h (FRAME_LEFT_INTERNAL_BORDER_START):

* redisplay.c (UPDATE_CACHE_RETURN):
* redisplay.c (pixel_to_glyph_translation):
* toolbar.c (update_frame_toolbars_geometry):
* window.c (Fwindow_pixel_edges):
Get rid of some redundant macros. Consistently use the
FRAME_TOP_*_START, FRAME_RIGHT_*_END, etc. format. Rename
FRAME_*_BORDER_* to FRAME_*_INTERNAL_BORDER_*. Comment out
FRAME_BOTTOM_* for gutters and the paned area due to the
uncertainty over where the paned area actually begins. (Eventually
we should probably move the gutters outside the minibuffer so that
the paned area is contiguous.) Use FRAME_PANED_* more often in the
code to make things clearer.
Update the diagram to show that the bottom gutter is inside the
minibuffer (!) and that there are "junk boxes" when you have left
and/or right gutters (dead boxes that are mistakenly left uncleared,
unlike the corresponding scrollbar dead boxes). Update the text
appropriately to cover the bottom gutter position, etc.
Rewrite gutter-geometry code to use the FRAME_*_GUTTER_* in place of
equivalent expressions referencing other frame elements, to make the
code more portable in case we move around the gutter location.
Cleanup FRAME_*_GUTTER_BOUNDS() in gutter.h.
Add some #### GEOM! comments where I think code is incorrect --
typically, it wasn't fixed up properly when the gutter was added.
Some cosmetic changes.

| 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 | |

| 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. | |

| 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. | |

| 526 This is similar to `let' but it does \"destructuring\", in that it matches | |
| 527 the structure of ARGS to the structure of EXPR and binds corresponding | |
| 528 arguments in ARGS to their values in EXPR. The format of ARGS, and the | |
| 529 way the destructuring works, is exactly like the destructuring that occurs | |
| 530 in `defmacro*'; see that for more information. | |
| 531 | |
| 532 An alternative means of destructuring is using the `loop' macro. `loop' | |
| 533 gives practical examples of destructuring. `defmacro*' describes the | |
| 534 differences between loop and macro-style destructuring. | |
| 535 | |
| 536 You can rewrite a call to (destructuring-bind ARGS EXPR &rest BODY) using | |

| 538 | |
| 539 (loop for ARGS = EXPR | |

| 772 (defmacro loop (&rest args) | |
| 773 "(loop CLAUSE...): The Common Lisp `loop' macro. | |
| 800 | 774 |
| 775 The loop macro consists of a series of clauses, which do things like | |
| 776 iterate variables, set conditions for exiting the loop, accumulating values | |
| 777 to be returned as the return value of the loop, and executing arbitrary | |
| 2297 | 778 blocks of code. Each clause is processed in turn, and the loop executes its |
| 800 | 779 body repeatedly until an exit condition is hit. |
| 780 | |
| 781 It's important to understand that loop clauses such as `for' and `while', | |
| 782 which look like loop-establishing constructs, don't actually *establish* a | |
| 783 loop\; the looping is established by the `loop' clause itself, which will | |
| 784 repeatedly process its body until told to stop. `while' merely establishes | |
| 785 a condition which, when true, causes the loop to finish, and `for' sets a | |
| 786 variable to different values on each iteration (e.g. successive elements of | |
| 787 a list) and sets an exit condition when there are no more values. This | |
| 788 means, for example, that if two `for' clauses appear, you don't get two | |
| 789 nested loops, but instead two variables that are stepped in parallel, and | |
| 790 two exit conditions, either of which, if triggered, will cause the loop to | |
| 791 end. Similarly for a loop with a `for' and a `while' clause. For example: | |
| 792 | |
| 793 \(loop | |
| 794 for x in list | |
| 795 while x | |
| 796 do ...) | |
| 797 | |
| 798 In each successive iteration, X is set to the next element of the list. If | |
| 799 there are no more elements, or if any element is nil (the `while' clause), | |
| 800 the loop exits. Otherwise, the block of code following `do' is executed.) | |
| 801 | |
| 802 This example also shows that some clauses establish variable bindings -- | |
| 803 essentially like a `let' binding -- and that following clauses can | |
| 804 reference these variables. Furthermore, the entire loop is surrounded by a | |
| 805 block named nil (unless the `named' clause is given), so you can return | |
| 806 from the loop using the macro `return'. (The other way to exit the loop is | |
| 807 through the macro `loop-finish'. The difference is that some loop clauses | |
| 808 establish or accumulate a value to be returned, and `loop-finish' returns | |
| 809 this. `return', however, can only return an explicitly-specified value. | |
| 810 NOTE CAREFULLY: There is a loop clause called `return' as well as a | |
| 811 standard Lisp macro called `return'. Normally they work similarly\; but if | |
| 812 you give the loop a name with `named', you will need to use the macro | |
| 813 `return-from'.) | |
| 814 | |
| 815 Another extremely useful feature of loops is called \"destructuring\". If, | |
| 816 in place of VAR, a list (possibly dotted, possibly a tree of arbitary | |
| 817 complexity) is given, the value to be assigned is assumed to have a similar | |
| 818 structure to the list given, and variables in the list will be matched up | |
| 819 with corresponding elements in the structure. For example: | |
| 820 | |
| 821 \(loop | |
| 822 for (x y) in '((foo 1) (bar 2) (baz 3)) | |
| 823 do (puthash x y some-hash-table)) | |
| 824 | |
| 825 will add three elements to a hash table, mapping foo -> 1, bar -> 2, and | |
| 826 baz -> 3. As other examples, you can conveniently process alists using | |
| 827 | |
| 828 \(loop for (x . y) in alist do ...) | |
| 829 | |
| 830 and plists using | |
| 831 | |
| 832 \(loop for (x y) on plist by #'cddr do ...) | |
| 833 | |
| 834 Destructuring is forgiving in that mismatches in the number of elements on | |
| 835 either size will be handled gracefully, either by ignoring or initializing | |
| 1123 | 836 to nil. Destructuring is extremely powerful, and is probably the single |
| 837 most useful feature of `loop'. | |
| 838 | |
| 839 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, | |
| 840 | |
| 841 \(loop for x being the hash-key in table using (hash-value y) | |
| 842 collect (cons x y)) | |
| 843 | |
| 844 converts hash-table TABLE to an alist. (What `collect' actually does is | |
| 845 push its value onto the end of an internal list and establish this list as | |
| 846 the default return value of the loop. See below for more information.) | |
| 847 | |
| 848 An example of in-place modification is | |
| 849 | |
| 850 \(setq foo '(1 3 5)) | |
| 851 \(loop for x in-ref foo do | |
| 852 (setf x (* x x))) | |
| 853 | |
| 854 after which foo will contain '(1 9 25). | |
| 800 | 855 |
| 856 If you don't understand how a particular loop clause works, create an | |
| 857 example and use `macroexpand-sexp' to expand the macro. | |
| 858 | |
| 428 | 859 Valid clauses are: |
| 800 | 860 |
| 861 \(NOTE: Keywords in lowercase\; slashes separate different possibilities | |
| 862 for keywords, some of which are synonymous\; brackets indicate optional | |
| 863 parts of the clause. In all of the clauses with `being', the word `being', | |
| 864 the words `each' or `the', and the difference between singular and plural | |
| 865 keywords are all just syntactic sugar. Stylistically, you should write | |
| 866 either `being each foo' or `being the foos'.) | |
| 867 | |
| 868 for VAR from/upfrom/downfrom NUM1 to/upto/downto/above/below NUM2 [by NUMSTEP] | |
| 869 Step VAR across numbers. `upfrom', `upto', and `below' explicitly | |
| 870 indicate upward stepping\; `downfrom', `downto', and `above' explicitly | |
| 871 indicate downward stepping. (If none of these is given, the default is | |
| 872 upward.) `to', `upto', and `downto' cause stepping to include NUM2 as | |
| 873 the last iteration, while `above' and `below' stop just before reaching | |
| 874 NUM2. `by' can be given to indicate a stepping increment other than 1. | |
| 875 | |
| 876 for VAR in LIST [by FUNC] | |
| 877 Step VAR over elements of a LIST. FUNC specifies how to get successive | |
| 878 sublists and defaults to `cdr'. | |
| 879 | |
| 880 for VAR on LIST [by FUNC] | |
| 881 Step VAR over tails of a LIST. FUNC specifies how to get successive | |
| 882 sublists and defaults to `cdr'. | |
| 883 | |
| 884 for VAR in-ref LIST [by FUNC] | |
| 885 Step VAR over elements of a LIST, like `for ... in', except the VAR is | |
| 886 bound using `symbol-macrolet' instead of `let'. In essence, VAR is set | |
| 887 to a \"reference\" to the list element instead of the element itself\; | |
| 888 this us, you can destructively modify the list using `setf' on VAR, and | |
| 889 any changes to the list will \"magically\" reflect themselves in | |
| 890 subsequent uses of VAR. | |
| 891 | |
| 892 for VAR = INIT [then EXPR] | |
| 893 Set VAR on each iteration of the loop. If only INIT is given, use it | |
| 894 on each iteration. Otherwise, use INIT on the first iteration and EXPR | |
| 895 on subsequent ones. | |
| 896 | |
| 897 for VAR across/across-ref ARRAY | |
| 898 Step VAR across a sequence other than a list (string, vector, bit | |
| 899 vector). If `across-ref' is given, VAR is bound using | |
| 900 `symbol-macrolet' instead of `let' -- see above. | |
| 901 | |
| 902 for VAR being each/the element/elements in/of/in-ref/of-ref SEQUENCE [using (index INDEX-VAR)] | |
| 903 Step VAR across any sequence. A variable can be specified with a | |
| 904 `using' phrase to receive the index, starting at 0. If `in-ref' or | |
| 905 `of-ref' is given, VAR is bound using `symbol-macrolet' instead of | |
| 906 `let' -- see above. | |
| 907 | |
| 908 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
| 909 | |
| 910 for VAR being each/the hash-key/hash-keys/hash-value/hash-values in/of HASH-TABLE [using (hash-value/hash-key OTHER-VAR)] | |
| 911 Map VAR over a hash table. The various keywords are synonymous except | |
| 912 those that distinguish between keys and values. The `using' phrase is | |
| 913 optional and allows both key and value to be bound. | |
| 914 | |
| 915 for VAR being each/the symbol/present-symbol/external-symbol/symbols/present-symbols/external-symbols in/of OBARRAY | |
| 916 Map VAR over the symbols in an obarray. All symbol keywords are | |
| 917 currently synonymous. | |
| 918 | |
| 919 for VAR being each/the extent/extents [in/of BUFFER-OR-STRING] [from POS] [to POS] | |
| 920 Map VAR over the extents in a buffer or string, defaulting to the | |
| 921 current buffer, the beginning and the end, respectively. | |
| 922 | |
| 923 for VAR being each/the interval/intervals [in/of BUFFER-OR-STRING] [property PROPERTY] [from POS] [to POS] | |
| 924 Map VAR over the intervals without property change in a buffer or | |
| 925 string, defaulting to the current buffer, the beginning and the end, | |
| 926 respectively. If PROPERTY is given, iteration occurs using | |
| 927 `next-single-property-change'\; otherwise, using | |
| 928 `next-property-change'. | |
| 929 | |
| 930 for VAR being each/the window/windows [in/of FRAME] | |
| 931 Step VAR over the windows in FRAME, defaulting to the selected frame. | |
| 932 | |
| 933 for VAR being each/the frame/frames | |
| 934 Step VAR over all frames. | |
| 935 | |
| 936 for VAR being each/the buffer/buffers [by FUNC] | |
| 937 Step VAR over all buffers. This is actually equivalent to | |
| 938 `for VAR in (buffer-list) [by FUNC]'. | |
| 939 | |
| 940 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)] | |
| 941 Map VAR over the entries in a keymap. Keyword `key-seq' causes | |
| 942 recursive mapping over prefix keymaps occurring in the keymap, with VAR | |
| 943 getting the built-up sequence (a vector). Otherwise, mapping does not | |
| 944 occur recursively. `key-code' and `key-seq' refer to what is bound | |
| 945 (second argument of `define-key'), and `key-binding' what it's bound to | |
| 946 (third argument of `define-key'). | |
| 947 | |
| 948 as VAR ... | |
| 949 `as' is a synonym for `for'. | |
| 950 | |
| 951 and VAR ... | |
| 952 `and' clauses have the same syntax as `for' clauses except that the | |
| 953 variables in the clause are bound in parallel with a preceding | |
| 954 `and'/`for' clause instead of in series. | |
| 955 | |
| 956 with VAR = INIT | |
| 957 Set VAR to INIT once, before doing any iterations. | |
| 958 | |
| 959 repeat NUM | |
| 960 Exit the loop if more than NUM iterations have occurred. | |
| 961 | |
| 962 while COND | |
| 963 Exit the loop if COND isn't true. | |
| 964 | |
| 965 until COND | |
| 966 Exit the loop if COND is true. | |
| 967 | |
| 968 collect EXPR [into VAR] | |
| 969 Push EXPR onto the end of a list of values -- stored either in VAR or a | |
| 970 temporary variable that will be returned as the return value of the | |
| 971 loop if it terminates through an exit condition or a call to | |
| 972 `loop-finish'. | |
| 973 | |
| 974 append EXPR [into VAR] | |
| 975 Append EXPR (a list) onto the end of a list of values, like `collect'. | |
| 976 | |
| 977 nconc EXPR [into VAR] | |
| 978 Nconc EXPR (a list) onto the end of a list of values, like `collect'. | |
| 979 | |
| 980 concat EXPR [into VAR] | |
| 981 Concatenate EXPR (a string) onto the end of a string of values, like | |
| 982 `collect'. | |
| 983 | |
| 984 vconcat EXPR [into VAR] | |
| 985 Concatenate EXPR (a vector) onto the end of a vector of values, like | |
| 986 `collect'. | |
| 987 | |
| 988 bvconcat EXPR [into VAR] | |
| 989 Concatenate EXPR (a bit vector) onto the end of a bit vector of values, | |
| 990 like `collect'. | |
| 991 | |
| 992 sum EXPR [into VAR] | |
| 993 Add EXPR to a value, like `collect'. | |
| 994 | |
| 995 count EXPR [into VAR] | |
| 996 If EXPR is true, increment a value by 1, like `collect'. | |
| 997 | |
| 998 maximize EXPR [into VAR] | |
| 999 IF EXPR is greater than a value, replace the value with EXPR, like | |
| 1000 `collect'. | |
| 1001 | |
| 1002 minimize EXPR [into VAR] | |
| 1003 IF EXPR is less than a value, replace the value with EXPR, like | |
| 1004 `collect'. | |
| 1005 | |
| 1006 always COND | |
| 1007 If COND is true, continue the loop and set the loop return value (the | |
| 1008 same value that's manipulated by `collect' and friends and is returned | |
| 1009 by a normal loop exit or an exit using `loop-finish') to t\; otherwise, | |
| 1010 exit the loop and return nil. The effect is to determine and return | |
| 1011 whether a condition is true \"always\" (all iterations of the loop). | |
| 1012 | |
| 1013 never COND | |
| 1014 If COND is false, continue the loop and set the loop return value (like | |
| 1015 `always') to t\; otherwise, exit the loop and return nil. The effect | |
| 1016 is to determine and return whether a condition is \"never\" true (all | |
| 1017 iterations of the loop). | |
| 1018 | |
| 1019 thereis COND | |
| 1020 If COND is true, exit the loop and return COND. | |
| 1021 | |
| 1022 if/when COND CLAUSE [and CLAUSE]... else CLAUSE [and CLAUSE...] | |
| 1023 If COND is true, execute the directly following clause(s)\; otherwise, | |
| 1024 execute the clauses following `else'. | |
| 1025 | |
| 1026 unless COND CLAUSE [and CLAUSE]... else CLAUSE [and CLAUSE...] | |
| 1027 If COND is false, execute the directly following clause(s)\; otherwise, execute the clauses following `else'. | |
| 1028 | |
| 1029 do EXPRS... | |
| 1030 Execute the expressions (any Lisp forms). | |
| 1031 | |
| 1032 initially EXPRS... | |
| 1033 Execute EXPR once, before doing any iterations, and after values have | |
| 1034 been set using `with'. | |
| 1035 | |
| 1036 finally EXPRS... | |
| 1037 Execute EXPR once, directly before the loop terminates. This will not | |
| 1038 be executed if the loop terminates prematurely as a result of `always', | |
| 1039 `never', `thereis', or `return'. | |
| 1040 | |
| 1041 return EXPR | |
| 1042 Exit from the loop and return EXPR. | |
| 1043 | |
| 1044 finally return EXPR | |
| 1045 Specify the value to be returned when the loop exits. (Unlike `return', | |
| 1046 this doesn't cause the loop to immediately exit\; it will exit whenever | |
| 1047 it normally would have.) This takes precedence over a return value | |
| 1048 specified with `collect' and friends or `always' and friends. | |
| 1049 | |
| 1050 named NAME | |
| 1051 Specify the name for block surrounding the loop, in place of nil. | |
| 1052 (See `block'.) | |

| 2014 "(defsetf NAME FUNC): define a `setf' method. | |
| 2015 This macro is an easy-to-use substitute for `define-setf-method' that works | |
| 2016 well for simple place forms. In the simple `defsetf' form, `setf's of | |
| 2017 the form (setf (NAME ARGS...) VAL) are transformed to function or macro | |
| 2018 calls of the form (FUNC ARGS... VAL). Example: (defsetf aref aset). | |
| 2019 Alternate form: (defsetf NAME ARGLIST (STORE) BODY...). | |
| 2020 Here, the above `setf' call is expanded by binding the argument forms ARGS | |
| 2021 according to ARGLIST, binding the value form VAL to STORE, then executing | |
| 2022 BODY, which must return a Lisp form that does the necessary `setf' operation. | |
| 2023 Actually, ARGLIST and STORE may be bound to temporary variables which are | |
| 2024 introduced automatically to preserve proper execution order of the arguments. | |
| 2025 Example: (defsetf nth (n x) (v) (list 'setcar (list 'nthcdr n x) v))." | |
