22 /* New face implementation by Gerd Moellmann <gerd@gnu.org>. */
26 When using Emacs with X, the display style of characters can be
27 changed by defining `faces'. Each face can specify the following
32 2. Relative proportionate width, aka character set width or set
33 width (swidth), e.g. `semi-compressed'.
35 3. Font height in 1/10pt.
37 4. Font weight, e.g. `bold'.
39 5. Font slant, e.g. `italic'.
45 8. Whether or not characters should be underlined, and in what color.
47 9. Whether or not characters should be displayed in inverse video.
49 10. A background stipple, a bitmap.
51 11. Whether or not characters should be overlined, and in what color.
53 12. Whether or not characters should be strike-through, and in what
56 13. Whether or not a box should be drawn around characters, the box
57 type, and, for simple boxes, in what color.
59 14. Font pattern, or nil. This is a special attribute.
60 When this attribute is specified, the face uses a font opened by
61 that pattern as is. In addition, all the other font-related
62 attributes (1st thru 5th) are generated from the opened font name.
63 On the other hand, if one of the other font-related attributes are
64 specified, this attribute is set to nil. In that case, the face
65 doesn't inherit this attribute from the `default' face, and uses a
66 font determined by the other attributes (those may be inherited
67 from the `default' face).
69 15. A face name or list of face names from which to inherit attributes.
71 16. A specified average font width, which is invisible from Lisp,
72 and is used to ensure that a font specified on the command line,
73 for example, can be matched exactly.
77 Faces are frame-local by nature because Emacs allows to define the
78 same named face (face names are symbols) differently for different
79 frames. Each frame has an alist of face definitions for all named
80 faces. The value of a named face in such an alist is a Lisp vector
81 with the symbol `face' in slot 0, and a slot for each of the face
82 attributes mentioned above.
84 There is also a global face alist `Vface_new_frame_defaults'. Face
85 definitions from this list are used to initialize faces of newly
88 A face doesn't have to specify all attributes. Those not specified
89 have a value of `unspecified'. Faces specifying all attributes but
90 the 14th are called `fully-specified'.
95 The display style of a given character in the text is determined by
96 combining several faces. This process is called `face merging'.
97 Any aspect of the display style that isn't specified by overlays or
98 text properties is taken from the `default' face. Since it is made
99 sure that the default face is always fully-specified, face merging
100 always results in a fully-specified face.
105 After all face attributes for a character have been determined by
106 merging faces of that character, that face is `realized'. The
107 realization process maps face attributes to what is physically
108 available on the system where Emacs runs. The result is a
109 `realized face' in form of a struct face which is stored in the
110 face cache of the frame on which it was realized.
112 Face realization is done in the context of the character to display
113 because different fonts may be used for different characters. In
114 other words, for characters that have different font
115 specifications, different realized faces are needed to display
118 Font specification is done by fontsets. See the comment in
119 fontset.c for the details. In the current implementation, all ASCII
120 characters share the same font in a fontset.
122 Faces are at first realized for ASCII characters, and, at that
123 time, assigned a specific realized fontset. Hereafter, we call
124 such a face as `ASCII face'. When a face for a multibyte character
125 is realized, it inherits (thus shares) a fontset of an ASCII face
126 that has the same attributes other than font-related ones.
128 Thus, all realized faces have a realized fontset.
133 Unibyte text (i.e. raw 8-bit characters) is displayed with the same
134 font as ASCII characters. That is because it is expected that
135 unibyte text users specify a font that is suitable both for ASCII
136 and raw 8-bit characters.
141 Font selection tries to find the best available matching font for a
142 given (character, face) combination.
144 If the face specifies a fontset name, that fontset determines a
145 pattern for fonts of the given character. If the face specifies a
146 font name or the other font-related attributes, a fontset is
147 realized from the default fontset. In that case, that
148 specification determines a pattern for ASCII characters and the
149 default fontset determines a pattern for multibyte characters.
151 Available fonts on the system on which Emacs runs are then matched
152 against the font pattern. The result of font selection is the best
153 match for the given face attributes in this font list.
155 Font selection can be influenced by the user.
157 1. The user can specify the relative importance he gives the face
158 attributes width, height, weight, and slant by setting
159 face-font-selection-order (faces.el) to a list of face attribute
160 names. The default is '(:width :height :weight :slant), and means
161 that font selection first tries to find a good match for the font
162 width specified by a face, then---within fonts with that
163 width---tries to find a best match for the specified font height,
166 2. Setting face-font-family-alternatives allows the user to
167 specify alternative font families to try if a family specified by a
170 3. Setting face-font-registry-alternatives allows the user to
171 specify all alternative font registries to try for a face
172 specifying a registry.
174 4. Setting face-ignored-fonts allows the user to ignore specific
178 Character composition.
180 Usually, the realization process is already finished when Emacs
181 actually reflects the desired glyph matrix on the screen. However,
182 on displaying a composition (sequence of characters to be composed
183 on the screen), a suitable font for the components of the
184 composition is selected and realized while drawing them on the
185 screen, i.e. the realization process is delayed but in principle
189 Initialization of basic faces.
191 The faces `default', `modeline' are considered `basic faces'.
192 When redisplay happens the first time for a newly created frame,
193 basic faces are realized for CHARSET_ASCII. Frame parameters are
194 used to fill in unspecified attributes of the default face. */
