| 66 | |
| 67 A face cache element caches the results of instantiating the | |
| 68 properties of a face in a particular window. (Instantiation can | |
| 69 take a long time so this is very important.) Each window contains | |
| 70 an array of face cache elements (called the "face cache"), one for | |
| 71 each face that has been seen in the window so far. | |
| 72 | |
| 73 Some tricky stuff is done to make sure the face cache does not | |
| 74 become inconsistent: | |
| 75 | |
| 76 1) Switching buffers in a window clears the face cache for that | |
| 77 window, because this can change the way any property is | |
| 78 instantiated in the window. | |
| 79 2) Setting a face property causes that face to be marked as | |
| 80 dirty. This causes various stuff to happen to make sure | |
| 81 the appropriate face cache elements are invalidated. | |
| 82 (#### Actually this doesn't work quite right, and errs | |
| 83 too much on the side of invalidating unnecessary stuff.) | |
| 84 | |
| 85 There are also face cache elements for "merged faces", which are the | |
| 86 result of merging all the faces that overlap a particular buffer | |
| 87 position. The merging is always done in the context of a particular | |
| 88 domain (specifically, a window), and the face cache element is | |
| 89 specific to a particular window. (Face cache elements are contained | |
| 90 in an array that is attached to each struct_window.) The reason that | |
| 91 the merging takes place in the context of a particular window has | |
| 92 to do with the way the merging works: | |
| 93 | |
| 94 1) All extents overlying the buffer position are sorted by descending | |
| 95 priority. | |
| 96 2) The property of a particular merged face comes from the highest- | |
| 97 priority face that specifies a value for that particular property. | |
| 98 3) The way to determine whether a face specifies a value for a | |
| 99 particular property is to instantiate that face's property in | |
| 100 the window in question with the no-fallback option set, to | |
| 101 see if we got anything. | |
| 102 | |
| 103 For Mule, things get a bit trickier because there can be multiple | |
| 104 fonts per face/window combination -- the charset is an argument | |
| 105 to specifier-instance. | |
| 106 | |
| 107 We have two possible data structure representations: | |
| 108 | |
| 109 1) Keep the original "one font per face cache element" representation | |
| 110 and use a different face cache element for each charset. | |
| 111 2) Allow multiple fonts to be in a single face cache element. | |
| 112 | |
| 113 I've chosen to use (2) -- the data structure gets more complicated | |
| 114 but the algorithms for maintaining face cache elements end up | |
| 115 simpler. | |

| 428 | 126 /* There are two kinds of cachels; those created from a single face |
| 127 and those created by merging more than one face. In the former | |
| 128 case, the FACE element specifies the face used. In the latter | |
| 129 case, the MERGED_FACES_STATIC and MERGED_FACES elements specify | |
| 130 the faces used for merging by giving the indices of the | |
| 131 corresponding single-face cachels. | |
| 132 | |
| 133 Formerly we didn't bother to keep track of the faces used for | |
| 442 | 134 merging. We do now because we need to do so because there is no |
| 428 | 135 other way to properly handle multiple charsets for Mule in the |
| 136 presence of display tables short of always computing the values | |
| 137 for all charsets, which is very expensive. Instead, we use a | |
| 138 lazy scheme where we only compute the font for a particular charset | |
| 139 when it is needed. (The exception is the font for the ASCII charset. | |
| 140 We always compute it, just like the other attributes, because | |
| 141 many places in the C code refer to the font of the ASCII charset | |
| 142 and expect it to always be there.) | |
| 143 | |
| 144 We store the first four faces in a static array, and use a | |
| 145 Dynarr for the rest. This has the advantage that the space used | |
| 146 is small but the Dynarr will almost never be created, so we | |
| 147 won't spend much time in malloc()/free(). | |
