545 | the default for new frames (this is done automatically each time an | |
546 | attribute is changed on all frames). | |
547 | ||
548 | ARGS must come in pairs ATTRIBUTE VALUE. ATTRIBUTE must be a valid | |
549 | face attribute name. All attributes can be set to `unspecified'; | |
550 | this fact is not further mentioned below. | |
551 | ||
552 | The following attributes are recognized: | |
553 | ||
554 | `:family' | |
555 | ||
556 | VALUE must be a string specifying the font family, e.g. ``courier'', | |
557 | or a fontset alias name. If a font family is specified, wild-cards `*' | |
558 | and `?' are allowed. | |
559 | ||
560 | `:width' | |
561 | ||
562 | VALUE specifies the relative proportionate width of the font to use. | |
563 | It must be one of the symbols `ultra-condensed', `extra-condensed', | |
564 | `condensed', `semi-condensed', `normal', `semi-expanded', `expanded', | |
565 | `extra-expanded', or `ultra-expanded'. | |
566 | ||
567 | `:height' | |
568 | ||
19feb949 MB |
569 | VALUE must be either an integer specifying the height of the font to use |
570 | in 1/10 pt, a floating point number specifying the amount by which to | |
571 | scale any underlying face, or a function, which is called with the old | |
572 | height (from the underlying face), and should return the new height. | |
5f5c8ee5 GM |
573 | |
574 | `:weight' | |
575 | ||
576 | VALUE specifies the weight of the font to use. It must be one of the | |
577 | symbols `ultra-bold', `extra-bold', `bold', `semi-bold', `normal', | |
578 | `semi-light', `light', `extra-light', `ultra-light'. | |
579 | ||
580 | `:slant' | |
581 | ||
582 | VALUE specifies the slant of the font to use. It must be one of the | |
583 | symbols `italic', `oblique', `normal', `reverse-italic', or | |
584 | `reverse-oblique'. | |
585 | ||
586 | `:foreground', `:background' | |
587 | ||
588 | VALUE must be a color name, a string. | |
589 | ||
590 | `:underline' | |
591 | ||
592 | VALUE specifies whether characters in FACE should be underlined. If | |
593 | VALUE is t, underline with foreground color of the face. If VALUE is | |
594 | a string, underline with that color. If VALUE is nil, explicitly | |
595 | don't underline. | |
596 | ||
597 | `:overline' | |
598 | ||
599 | VALUE specifies whether characters in FACE should be overlined. If | |
600 | VALUE is t, overline with foreground color of the face. If VALUE is a | |
601 | string, overline with that color. If VALUE is nil, explicitly don't | |
602 | overline. | |
603 | ||
604 | `:strike-through' | |
605 | ||
606 | VALUE specifies whether characters in FACE should be drawn with a line | |
607 | striking through them. If VALUE is t, use the foreground color of the | |
608 | face. If VALUE is a string, strike-through with that color. If VALUE | |
609 | is nil, explicitly don't strike through. | |
610 | ||
611 | `:box' | |
612 | ||
613 | VALUE specifies whether characters in FACE should have a box drawn | |
614 | around them. If VALUE is nil, explicitly don't draw boxes. If | |
615 | VALUE is t, draw a box with lines of width 1 in the foreground color | |
616 | of the face. If VALUE is a string, the string must be a color name, | |
617 | and the box is drawn in that color with a line width of 1. Otherwise, | |
618 | VALUE must be a property list of the form `(:line-width WIDTH | |
619 | :color COLOR :style STYLE)'. If a keyword/value pair is missing from | |
620 | the property list, a default value will be used for the value, as | |
621 | specified below. WIDTH specifies the width of the lines to draw; it | |
0f937ebd KH |
622 | defaults to 1. If WIDTH is negative, the absolute value is the width |
623 | of the lines, and draw top/bottom lines inside the characters area, | |
624 | not around it. COLOR is the name of the color to draw in, default is | |
5f5c8ee5 GM |
625 | the foreground color of the face for simple boxes, and the background |
626 | color of the face for 3D boxes. STYLE specifies whether a 3D box | |
627 | should be draw. If STYLE is `released-button', draw a box looking | |
628 | like a released 3D button. If STYLE is `pressed-button' draw a box | |
629 | that appears like a pressed button. If STYLE is nil, the default if | |
630 | the property list doesn't contain a style specification, draw a 2D | |
631 | box. | |
632 | ||
633 | `:inverse-video' | |
634 | ||
635 | VALUE specifies whether characters in FACE should be displayed in | |
70d0c3b0 | 636 | inverse video. VALUE must be one of t or nil. |
5f5c8ee5 GM |
637 | |
638 | `:stipple' | |
639 | ||
640 | If VALUE is a string, it must be the name of a file of pixmap data. | |
641 | The directories listed in the `x-bitmap-file-path' variable are | |
642 | searched. Alternatively, VALUE may be a list of the form (WIDTH | |
643 | HEIGHT DATA) where WIDTH and HEIGHT are the size in pixels, and DATA | |
644 | is a string containing the raw bits of the bitmap. VALUE nil means | |
645 | explicitly don't use a stipple pattern. | |
646 | ||
647 | For convenience, attributes `:family', `:width', `:height', `:weight', | |
648 | and `:slant' may also be set in one step from an X font name: | |
649 | ||
650 | `:font' | |
651 | ||
652 | Set font-related face attributes from VALUE. VALUE must be a valid | |
653 | XLFD font name. If it is a font name pattern, the first matching font | |
654 | will be used. | |
655 | ||
656 | For compatibility with Emacs 20, keywords `:bold' and `:italic' can | |
657 | be used to specify that a bold or italic font should be used. VALUE | |
19feb949 MB |
658 | must be t or nil in that case. A value of `unspecified' is not allowed. |
659 | ||
660 | `:inherit' | |
661 | ||
662 | VALUE is the name of a face from which to inherit attributes, or a list | |
663 | of face names. Attributes from inherited faces are merged into the face | |
664 | like an underlying face would be, with higher priority than underlying faces." | |
