548 | the default for new frames (this is done automatically each time an | |
549 | attribute is changed on all frames). | |
550 | ||
551 | ARGS must come in pairs ATTRIBUTE VALUE. ATTRIBUTE must be a valid | |
552 | face attribute name. All attributes can be set to `unspecified'; | |
553 | this fact is not further mentioned below. | |
554 | ||
555 | The following attributes are recognized: | |
556 | ||
557 | `:family' | |
558 | ||
559 | VALUE must be a string specifying the font family, e.g. ``courier'', | |
560 | or a fontset alias name. If a font family is specified, wild-cards `*' | |
561 | and `?' are allowed. | |
562 | ||
563 | `:width' | |
564 | ||
565 | VALUE specifies the relative proportionate width of the font to use. | |
566 | It must be one of the symbols `ultra-condensed', `extra-condensed', | |
567 | `condensed', `semi-condensed', `normal', `semi-expanded', `expanded', | |
568 | `extra-expanded', or `ultra-expanded'. | |
569 | ||
570 | `:height' | |
571 | ||
19feb949 MB |
572 | VALUE must be either an integer specifying the height of the font to use |
573 | in 1/10 pt, a floating point number specifying the amount by which to | |
574 | scale any underlying face, or a function, which is called with the old | |
575 | height (from the underlying face), and should return the new height. | |
5f5c8ee5 GM |
576 | |
577 | `:weight' | |
578 | ||
579 | VALUE specifies the weight of the font to use. It must be one of the | |
580 | symbols `ultra-bold', `extra-bold', `bold', `semi-bold', `normal', | |
581 | `semi-light', `light', `extra-light', `ultra-light'. | |
582 | ||
583 | `:slant' | |
584 | ||
585 | VALUE specifies the slant of the font to use. It must be one of the | |
586 | symbols `italic', `oblique', `normal', `reverse-italic', or | |
587 | `reverse-oblique'. | |
588 | ||
589 | `:foreground', `:background' | |
590 | ||
591 | VALUE must be a color name, a string. | |
592 | ||
593 | `:underline' | |
594 | ||
595 | VALUE specifies whether characters in FACE should be underlined. If | |
596 | VALUE is t, underline with foreground color of the face. If VALUE is | |
597 | a string, underline with that color. If VALUE is nil, explicitly | |
598 | don't underline. | |
599 | ||
600 | `:overline' | |
601 | ||
602 | VALUE specifies whether characters in FACE should be overlined. If | |
603 | VALUE is t, overline with foreground color of the face. If VALUE is a | |
604 | string, overline with that color. If VALUE is nil, explicitly don't | |
605 | overline. | |
606 | ||
607 | `:strike-through' | |
608 | ||
609 | VALUE specifies whether characters in FACE should be drawn with a line | |
610 | striking through them. If VALUE is t, use the foreground color of the | |
611 | face. If VALUE is a string, strike-through with that color. If VALUE | |
612 | is nil, explicitly don't strike through. | |
613 | ||
614 | `:box' | |
615 | ||
616 | VALUE specifies whether characters in FACE should have a box drawn | |
617 | around them. If VALUE is nil, explicitly don't draw boxes. If | |
618 | VALUE is t, draw a box with lines of width 1 in the foreground color | |
619 | of the face. If VALUE is a string, the string must be a color name, | |
620 | and the box is drawn in that color with a line width of 1. Otherwise, | |
621 | VALUE must be a property list of the form `(:line-width WIDTH | |
622 | :color COLOR :style STYLE)'. If a keyword/value pair is missing from | |
623 | the property list, a default value will be used for the value, as | |
624 | specified below. WIDTH specifies the width of the lines to draw; it | |
0f937ebd KH |
625 | defaults to 1. If WIDTH is negative, the absolute value is the width |
626 | of the lines, and draw top/bottom lines inside the characters area, | |
627 | not around it. COLOR is the name of the color to draw in, default is | |
5f5c8ee5 GM |
628 | the foreground color of the face for simple boxes, and the background |
629 | color of the face for 3D boxes. STYLE specifies whether a 3D box | |
630 | should be draw. If STYLE is `released-button', draw a box looking | |
631 | like a released 3D button. If STYLE is `pressed-button' draw a box | |
632 | that appears like a pressed button. If STYLE is nil, the default if | |
633 | the property list doesn't contain a style specification, draw a 2D | |
634 | box. | |
635 | ||
636 | `:inverse-video' | |
637 | ||
638 | VALUE specifies whether characters in FACE should be displayed in | |
70d0c3b0 | 639 | inverse video. VALUE must be one of t or nil. |
5f5c8ee5 GM |
640 | |
641 | `:stipple' | |
642 | ||
643 | If VALUE is a string, it must be the name of a file of pixmap data. | |
644 | The directories listed in the `x-bitmap-file-path' variable are | |
645 | searched. Alternatively, VALUE may be a list of the form (WIDTH | |
646 | HEIGHT DATA) where WIDTH and HEIGHT are the size in pixels, and DATA | |
647 | is a string containing the raw bits of the bitmap. VALUE nil means | |
648 | explicitly don't use a stipple pattern. | |
649 | ||
650 | For convenience, attributes `:family', `:width', `:height', `:weight', | |
651 | and `:slant' may also be set in one step from an X font name: | |
652 | ||
653 | `:font' | |
654 | ||
655 | Set font-related face attributes from VALUE. VALUE must be a valid | |
656 | XLFD font name. If it is a font name pattern, the first matching font | |
657 | will be used. | |
658 | ||
659 | For compatibility with Emacs 20, keywords `:bold' and `:italic' can | |
660 | be used to specify that a bold or italic font should be used. VALUE | |
19feb949 MB |
661 | must be t or nil in that case. A value of `unspecified' is not allowed. |
662 | ||
663 | `:inherit' | |
664 | ||
665 | VALUE is the name of a face from which to inherit attributes, or a list | |
666 | of face names. Attributes from inherited faces are merged into the face | |
667 | like an underlying face would be, with higher priority than underlying faces." | |
