annotate src/glyphs.c @ 4539:061e030e3270
Fix some bugs in load-history construction, built-in symbol file names.
lib-src/ChangeLog addition:
2008-12-27 Aidan Kehoe <kehoea@parhasard.net>
* make-docfile.c (main): Allow more than one -d argument, followed
by a directory to change to.
(put_filename): Don't strip directory information; with previous
change, allows retrieval of Lisp function and variable origin
files from #'built-in-symbol-file relative to lisp-directory.
(scan_lisp_file): Don't add an extraneous newline after the file
name, put_filename has added the newline already.
lisp/ChangeLog addition:
2008-12-27 Aidan Kehoe <kehoea@parhasard.net>
* loadup.el (load-history):
Add the contents of current-load-list to load-history before
clearing it. Move the variable declarations earlier in the file to
a format understood by make-docfile.c.
* custom.el (custom-declare-variable): Add the variable's symbol
to the current file's load history entry correctly, don't use a
cons. Eliminate a comment that we don't need to worry about, we
don't need to check the `initialized' C variable in Lisp.
* bytecomp.el (byte-compile-output-file-form):
Merge Andreas Schwab's pre-GPLv3 GNU change of 19970831 here;
treat #'custom-declare-variable correctly, generating the
docstrings in a format understood by make-docfile.c.
* loadhist.el (symbol-file): Correct behaviour for checking
autoloaded macros and functions when supplied with a TYPE
argument. Accept fully-qualified paths from
#'built-in-symbol-file; if a path is not fully-qualified, return
it relative to lisp-directory if the filename corresponds to a
Lisp file, and relative to (concat source-directory "/src/")
otherwise.
* make-docfile.el (preloaded-file-list):
Rationalise some let bindings a little. Use the "-d" argument to
make-docfile.c to supply Lisp paths relative to lisp-directory,
not absolutely. Add in loadup.el explicitly to the list of files
to be processed by make-docfile.c--it doesn't make sense to add it
to preloaded-file-list, since that is used for purposes of
byte-compilation too.
src/ChangeLog addition:
2008-12-27 Aidan Kehoe <kehoea@parhasard.net>
* doc.c (Fbuilt_in_symbol_file):
Return a subr's filename immediately if we've found it. Check for
compiled function and compiled macro docstrings in DOC too, and
return them if they exist.
The branch of the if statement focused on functions may have
executed, but we may still want to check variable bindings; an
else clause isn't appropriate.

| 1555 Image-instance objects encapsulate the way a particular image (pixmap, | |
| 1556 etc.) is displayed on a particular device. In most circumstances, you | |
| 1557 do not need to directly create image instances; use a glyph instead. | |
| 1558 However, it may occasionally be useful to explicitly create image | |
| 1559 instances, if you want more control over the instantiation process. | |
| 1560 | |
| 1561 DATA is an image instantiator, which describes the image; see | |
| 442 | 1562 `make-image-specifier' for a description of the allowed values. |
| 428 | 1563 |
| 1564 DEST-TYPES should be a list of allowed image instance types that can | |
| 1565 be generated. The recognized image instance types are | |
| 1566 | |
| 2959 | 1567 `nothing' |
| 428 | 1568 Nothing is displayed. |
| 2959 | 1569 `text' |
| 428 | 1570 Displayed as text. The foreground and background colors and the |
| 1571 font of the text are specified independent of the pixmap. Typically | |
| 1572 these attributes will come from the face of the surrounding text, | |
| 1573 unless a face is specified for the glyph in which the image appears. | |
| 2959 | 1574 `mono-pixmap' |
| 428 | 1575 Displayed as a mono pixmap (a pixmap with only two colors where the |
| 1576 foreground and background can be specified independent of the pixmap; | |
| 1577 typically the pixmap assumes the foreground and background colors of | |
| 1578 the text around it, unless a face is specified for the glyph in which | |
| 1579 the image appears). | |
| 2959 | 1580 `color-pixmap' |
| 428 | 1581 Displayed as a color pixmap. |
| 2959 | 1582 `pointer' |
| 428 | 1583 Used as the mouse pointer for a window. |
| 2959 | 1584 `subwindow' |
| 428 | 1585 A child window that is treated as an image. This allows (e.g.) |
| 1586 another program to be responsible for drawing into the window. | |
| 2959 | 1587 `widget' |
| 428 | 1588 A child window that contains a window-system widget, e.g. a push |
| 442 | 1589 button, text field, or slider. |
| 1590 | |
| 1591 The DEST-TYPES list is unordered. If multiple destination types are | |
| 1592 possible for a given instantiator, the "most natural" type for the | |
| 1593 instantiator's format is chosen. (For XBM, the most natural types are | |
| 1594 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For | |
| 1595 the other normal image formats, the most natural types are | |
| 1596 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For | |
| 1597 the string and formatted-string formats, the most natural types are | |
| 1598 `text', followed by `mono-pixmap' (not currently implemented), | |
| 1599 followed by `color-pixmap' (not currently implemented). For MS | |
| 1600 Windows resources, the most natural type for pointer resources is | |
| 1601 `pointer', and for the others it's `color-pixmap'. The other formats | |
| 1602 can only be instantiated as one type. (If you want to control more | |
| 1603 specifically the order of the types into which an image is | |
| 1604 instantiated, just call `make-image-instance' repeatedly until it | |
| 1605 succeeds, passing less and less preferred destination types each | |
| 1606 time.) | |
| 1607 | |
| 1608 See `make-image-specifier' for a description of the different image | |
| 1609 instantiator formats. | |
| 428 | 1610 |
| 1611 If DEST-TYPES is omitted, all possible types are allowed. | |
| 1612 | |
| 442 | 1613 DOMAIN specifies the domain to which the image instance will be attached. |
| 1614 This domain is termed the \"governing domain\". The type of the governing | |
| 1615 domain depends on the image instantiator format. (Although, more correctly, | |
| 1616 it should probably depend on the image instance type.) For example, pixmap | |
| 1617 image instances are specific to a device, but widget image instances are | |
| 1618 specific to a particular XEmacs window because in order to display such a | |
| 1619 widget when two windows onto the same buffer want to display the widget, | |
| 1620 two separate underlying widgets must be created. (That's because a widget | |
| 1621 is actually a child window-system window, and all window-system windows have | |
| 1622 a unique existence on the screen.) This means that the governing domain for | |
| 1623 a pixmap image instance will be some device (most likely, the only existing | |
| 1624 device), whereas the governing domain for a widget image instance will be | |
| 1625 some XEmacs window. | |
| 1626 | |
| 1627 If you specify an overly general DOMAIN (e.g. a frame when a window was | |
| 1628 wanted), an error is signaled. If you specify an overly specific DOMAIN | |
| 1629 \(e.g. a window when a device was wanted), the corresponding general domain | |
| 1630 is fetched and used instead. For `make-image-instance', it makes no | |
| 1631 difference whether you specify an overly specific domain or the properly | |
| 1632 general domain derived from it. However, it does matter when creating an | |
| 1633 image instance by instantiating a specifier or glyph (e.g. with | |
| 1634 `glyph-image-instance'), because the more specific domain causes spec lookup | |
| 1635 to start there and proceed to more general domains. (It would also matter | |
| 1636 when creating an image instance with an instantiator format of `inherit', | |
| 1637 but we currently disallow this. #### We should fix this.) | |
| 1638 | |
| 1639 If omitted, DOMAIN defaults to the selected window. | |
| 1640 | |
| 444 | 1641 NOERROR controls what happens when the image cannot be generated. |
| 428 | 1642 If nil, an error message is generated. If t, no messages are |
| 1643 generated and this function returns nil. If anything else, a warning | |
| 440 | 1644 message is generated and this function returns nil. |

| 5534 display tables that apply (obtained by calling `specifier-instance' on | |
| 5535 `current-display-table' and any overriding display tables specified in | |
| 5536 currently active faces). The first entry found that matches the | |
| 5537 character determines how the character is displayed. If there is no | |
| 5538 matching entry, the default display method is used. (Non-control | |
| 5539 characters are displayed as themselves and control characters are | |
| 5540 displayed according to the buffer-local variable `ctl-arrow'. Control | |
| 5541 characters are further affected by `control-arrow-glyph' and | |
| 5542 `octal-escape-glyph'.) | |
| 5543 | |
| 5544 Each instantiator in this specifier and the display-table specifiers | |
| 5545 in faces is a display table or a list of such tables. If a list, each | |
| 5546 table will be searched in turn for an entry matching a particular | |
| 5547 character. Each display table is one of | |
| 5548 | |
| 5549 -- a vector, specifying values for characters starting at 0 | |
| 5550 -- a char table, either of type `char' or `generic' | |
| 5551 -- a range table | |
| 5552 | |
| 5553 Each entry in a display table should be one of | |
| 5554 | |
| 5555 -- nil (this entry is ignored and the search continues) | |
| 5556 -- a character (use this character; if it happens to be the same as | |

| 5558 redisplay attempts to display this character directly; | |
| 5559 #### At some point recursive display-table lookup will be | |

| 5561 -- a string (display each character in the string directly; | |

| 5564 -- a glyph (display the glyph; | |
