467 | FRAME nil means change attributes on all frames. FRAME t means change | |
468 | the default for new frames (this is done automatically each time an | |
469 | attribute is changed on all frames). | |
470 | ||
471 | ARGS must come in pairs ATTRIBUTE VALUE. ATTRIBUTE must be a valid | |
472 | face attribute name. All attributes can be set to `unspecified'; | |
473 | this fact is not further mentioned below. | |
474 | ||
475 | The following attributes are recognized: | |
476 | ||
477 | `:family' | |
478 | ||
479 | VALUE must be a string specifying the font family, e.g. ``courier'', | |
480 | or a fontset alias name. If a font family is specified, wild-cards `*' | |
481 | and `?' are allowed. | |
482 | ||
483 | `:width' | |
484 | ||
485 | VALUE specifies the relative proportionate width of the font to use. | |
486 | It must be one of the symbols `ultra-condensed', `extra-condensed', | |
487 | `condensed', `semi-condensed', `normal', `semi-expanded', `expanded', | |
488 | `extra-expanded', or `ultra-expanded'. | |
489 | ||
490 | `:height' | |
491 | ||
19feb949 MB |
492 | VALUE must be either an integer specifying the height of the font to use |
493 | in 1/10 pt, a floating point number specifying the amount by which to | |
494 | scale any underlying face, or a function, which is called with the old | |
495 | height (from the underlying face), and should return the new height. | |
5f5c8ee5 GM |
496 | |
497 | `:weight' | |
498 | ||
499 | VALUE specifies the weight of the font to use. It must be one of the | |
500 | symbols `ultra-bold', `extra-bold', `bold', `semi-bold', `normal', | |
501 | `semi-light', `light', `extra-light', `ultra-light'. | |
502 | ||
503 | `:slant' | |
504 | ||
505 | VALUE specifies the slant of the font to use. It must be one of the | |
506 | symbols `italic', `oblique', `normal', `reverse-italic', or | |
507 | `reverse-oblique'. | |
508 | ||
509 | `:foreground', `:background' | |
510 | ||
511 | VALUE must be a color name, a string. | |
512 | ||
513 | `:underline' | |
514 | ||
515 | VALUE specifies whether characters in FACE should be underlined. If | |
516 | VALUE is t, underline with foreground color of the face. If VALUE is | |
517 | a string, underline with that color. If VALUE is nil, explicitly | |
518 | don't underline. | |
519 | ||
520 | `:overline' | |
521 | ||
522 | VALUE specifies whether characters in FACE should be overlined. If | |
523 | VALUE is t, overline with foreground color of the face. If VALUE is a | |
524 | string, overline with that color. If VALUE is nil, explicitly don't | |
525 | overline. | |
526 | ||
527 | `:strike-through' | |
528 | ||
529 | VALUE specifies whether characters in FACE should be drawn with a line | |
530 | striking through them. If VALUE is t, use the foreground color of the | |
531 | face. If VALUE is a string, strike-through with that color. If VALUE | |
532 | is nil, explicitly don't strike through. | |
533 | ||
534 | `:box' | |
535 | ||
536 | VALUE specifies whether characters in FACE should have a box drawn | |
537 | around them. If VALUE is nil, explicitly don't draw boxes. If | |
538 | VALUE is t, draw a box with lines of width 1 in the foreground color | |
539 | of the face. If VALUE is a string, the string must be a color name, | |
540 | and the box is drawn in that color with a line width of 1. Otherwise, | |
541 | VALUE must be a property list of the form `(:line-width WIDTH | |
542 | :color COLOR :style STYLE)'. If a keyword/value pair is missing from | |
543 | the property list, a default value will be used for the value, as | |
544 | specified below. WIDTH specifies the width of the lines to draw; it | |
0f937ebd KH |
545 | defaults to 1. If WIDTH is negative, the absolute value is the width |
546 | of the lines, and draw top/bottom lines inside the characters area, | |
547 | not around it. COLOR is the name of the color to draw in, default is | |
5f5c8ee5 GM |
548 | the foreground color of the face for simple boxes, and the background |
549 | color of the face for 3D boxes. STYLE specifies whether a 3D box | |
550 | should be draw. If STYLE is `released-button', draw a box looking | |
551 | like a released 3D button. If STYLE is `pressed-button' draw a box | |
552 | that appears like a pressed button. If STYLE is nil, the default if | |
553 | the property list doesn't contain a style specification, draw a 2D | |
554 | box. | |
555 | ||
556 | `:inverse-video' | |
557 | ||
558 | VALUE specifies whether characters in FACE should be displayed in | |
70d0c3b0 | 559 | inverse video. VALUE must be one of t or nil. |
5f5c8ee5 GM |
560 | |
561 | `:stipple' | |
562 | ||
563 | If VALUE is a string, it must be the name of a file of pixmap data. | |
564 | The directories listed in the `x-bitmap-file-path' variable are | |
565 | searched. Alternatively, VALUE may be a list of the form (WIDTH | |
566 | HEIGHT DATA) where WIDTH and HEIGHT are the size in pixels, and DATA | |
567 | is a string containing the raw bits of the bitmap. VALUE nil means | |
568 | explicitly don't use a stipple pattern. | |
569 | ||
570 | For convenience, attributes `:family', `:width', `:height', `:weight', | |
571 | and `:slant' may also be set in one step from an X font name: | |
572 | ||
573 | `:font' | |
574 | ||
575 | Set font-related face attributes from VALUE. VALUE must be a valid | |
576 | XLFD font name. If it is a font name pattern, the first matching font | |
577 | will be used. | |
578 | ||
579 | For compatibility with Emacs 20, keywords `:bold' and `:italic' can | |
580 | be used to specify that a bold or italic font should be used. VALUE | |
19feb949 MB |
581 | must be t or nil in that case. A value of `unspecified' is not allowed. |
582 | ||
583 | `:inherit' | |
584 | ||
585 | VALUE is the name of a face from which to inherit attributes, or a list | |
586 | of face names. Attributes from inherited faces are merged into the face | |
587 | like an underlying face would be, with higher priority than underlying faces." | |
