483
|

484 By "truename" we mean an XLFD-form name which contains no wildcards, yet
|
|
|
485 which resolves to *exactly* the same font as the one which we already have
|
|
|
486 the (probably wildcarded) name and `XFontStruct' of.
|
|
|
487
|
|
|
488 One might think that the first font returned by XListFonts would be the one
|
|
|
489 that XOpenFont would pick. Apparently this is the case on some servers,
|
|
|
490 but not on others. It would seem not to be specified.
|
|
|
491
|
|
|
492 The MIT R5 server sometimes appears to be picking the lexicographically
|
|
|
493 smallest font which matches the name (thus picking "adobe" fonts before
|
|
|
494 "bitstream" fonts even if the bitstream fonts are earlier in the path, and
|
|
|
495 also picking 100dpi adobe fonts over 75dpi adobe fonts even though the
|
|
|
496 75dpi are in the path earlier) but sometimes appears to be doing something
|
|
442
|
497 else entirely (for example, removing the bitstream fonts from the path will
|
|
428
|
498 cause the 75dpi adobe fonts to be used instead of the 100dpi, even though
|
|
|
499 their relative positions in the path (and their names!) have not changed).
|
|
|
500
|
|
|
501 The documentation for XSetFontPath() seems to indicate that the order of
|
|
442
|
502 entries in the font path means something, but it's pretty noncommittal about
|
|
428
|
503 it, and the spirit of the law is apparently not being obeyed...
|
|
|
504
|
|
|
505 All the fonts I've seen have a property named `FONT' which contains the
|
|
|
506 truename of the font. However, there are two problems with using this: the
|
|
|
507 first is that the X Protocol Document is quite explicit that all properties
|
|
|
508 are optional, so we can't depend on it being there. The second is that
|
|
|
509 it's conceivable that this alleged truename isn't actually accessible as a
|
|
|
510 font, due to some difference of opinion between the font designers and
|
|
|
511 whoever installed the font on the system.
|
|
|
512
|
|
|
513 So, our first attempt is to look for a FONT property, and then verify that
|
|
|
514 the name there is a valid name by running XListFonts on it. There's still
|
|
|
515 the potential that this could be true but we could still be being lied to,
|
|
|
516 but that seems pretty remote.
|
|
|
517
|
|
|
518 Late breaking news: I've gotten reports that SunOS 4.1.3U1
|
|
|
519 with OpenWound 3.0 has a font whose truename is really
|
|
|
520 "-Adobe-Courier-Medium-R-Normal--12-120-75-75-M-70-ISO8859-1"
|
|
|
521 but whose FONT property contains "Courier".
|
|
|
522
|
|
|
523 So we disbelieve the FONT property unless it begins with a dash and
|
|
|
524 is more than 30 characters long. X Windows: The defacto substandard.
|
|
|
525 X Windows: Complex nonsolutions to simple nonproblems. X Windows:
|
|
|
526 Live the nightmare.
|
|
|
527
|
|
|
528 If the FONT property doesn't exist, then we try and construct an XLFD name
|
|
|
529 out of the other font properties (FOUNDRY, FAMILY_NAME, WEIGHT_NAME, etc).
|
|
|
530 This is necessary at least for some versions of OpenWound. But who knows
|
|
|
531 what the future will bring.
|
|
|
532
|
|
|
533 If that doesn't work, then we use XListFonts and either take the first font
|
|
|
534 (which I think is the most sensible thing) or we find the lexicographically
|
|
|
535 least, depending on whether the preprocessor constant `XOPENFONT_SORTS' is
|
|
|
536 defined. This sucks because the two behaviors are a property of the server
|
|
|
537 being used, not the architecture on which emacs has been compiled. Also,
|
|
|
538 as I described above, sorting isn't ALWAYS what the server does. Really it
|
|
|
539 does something seemingly random. There is no reliable way to win if the
|
|
|
540 FONT property isn't present.
|
|
|
541
|
|
|
542 Another possibility which I haven't bothered to implement would be to map
|
|
|
543 over all of the matching fonts and find the first one that has the same
|
|
|
544 character metrics as the font we already have loaded. Even if this didn't
|
|
|
545 return exactly the same font, it would at least return one whose characters
|
|
|
546 were the same sizes, which would probably be good enough.
|
|
|
547
|
|
|
548 More late-breaking news: on RS/6000 AIX 3.2.4, the expression
|
|
|
549 XLoadQueryFont (dpy, "-*-Fixed-Medium-R-*-*-*-130-75-75-*-*-ISO8859-1")
|
|
|
550 actually returns the font
|
|
|
551 -Misc-Fixed-Medium-R-Normal--13-120-75-75-C-80-ISO8859-1
|
|
|
552 which is crazy, because that font doesn't even match that pattern! It is
|
|
|
553 also not included in the output produced by `xlsfonts' with that pattern.
|
|
|
554
|
|
|
555 So this is yet another example of XListFonts() and XOpenFont() using
|
|
|
556 completely different algorithms. This, however, is a goofier example of
|
|
|
557 this bug, because in this case, it's not just the search order that is
|
|
|
558 different -- the sets don't even intersect.
|
|
|
559
|
|
|
560 If anyone has any better ideas how to do this, or any insights on what it is
|
|
|
561 that the various servers are actually doing, please let me know! -- jwz. */
