20 | !!DESCRIPTION | ||
21 | |||
22 | |||
23 | Defoma stands for Debian Font Manager. It provides automatic | ||
24 | font configuration framework. Please refer the manpage of | ||
25 | defoma-font, defoma-app, or defoma-subst for the detailed | ||
26 | information of each command. This page describes the | ||
27 | introduction of Defoma. | ||
28 | |||
29 | |||
30 | Generally fonts are used by various applications, but | ||
31 | there's no way to configure them properly for each | ||
32 | application, especially for higher level ones like word | ||
33 | processor and illustrator. Defoma is a solution to this | ||
34 | problem. It calls configuration scripts installed by | ||
35 | applications whenever a font is installed/removed to update | ||
36 | the font configuration of applications. | ||
37 | |||
38 | |||
39 | __Defoma-configuration script__ is a perl library that | ||
40 | each application should install as | ||
41 | ''application-name''.defoma under | ||
42 | /usr/share/defoma/scripts and which configures about a font | ||
43 | for the application. Following is the example of the script | ||
44 | named foo.defoma. | ||
45 | |||
46 | |||
47 | @ACCEPT_CATEGORIES = qw(type1 truetype); | ||
48 | package foo; | ||
49 | sub type1 { | ||
50 | my $com = shift; | ||
51 | ... | ||
52 | } | ||
53 | sub truetype { | ||
54 | my $com = shift; | ||
55 | ... | ||
56 | } | ||
57 | 1; | ||
58 | This example represents an application ''foo'' wants to con- figure ''truetype'' and ''type1'' category fonts. Each function whose name is the same as a category is called with com- mand and additional arguments from Defoma. Following is a list of commands. | ||
59 | |||
60 | |||
61 | * register | ||
62 | * unregister | ||
63 | * do-install-real do-install-alias do-install-subst | ||
64 | * do-remove-real do-remove-alias do-remove-subst | ||
65 | * init | ||
66 | * term | ||
67 | * purge | ||
68 | ''do-install-*'' and ''do-remove-*'' commands are called from __Id cache__ so they are never passed unless the script makes use of it. ''init'' and ''term'' are called before/after the regis- tration and unregistration starts/finishes, respectively. | ||
69 | |||
70 | |||
71 | __Id cache__ is another feature of Defoma. The possible | ||
72 | prob- lem of automatic configuration is name space | ||
73 | confliction. Usually applications access fonts through their | ||
74 | logical font names (like XLFDs and !PostScript font names) | ||
75 | rather than the fonts themselves (like font files). Logical | ||
76 | font names, called identifier in Defoma, can easily | ||
77 | confclict especially if aliases are permitted. Through Id | ||
78 | cache mechanism, only one font is actually installed for | ||
79 | each identifier even if several fonts provide the same | ||
80 | identi- fier. | ||
81 | |||
82 | |||
83 | __Id Substitution__ is additional feature to __Id | ||
84 | cache__. It makes a certain font provide a certain id | ||
85 | specified in a rulefile. Rulefile describes | ||
86 | need-to-be-substituted (in other words, required) ids and | ||
87 | their hints, called rule. The rule is used to have more | ||
88 | similar-looking fonts with the same characters substitute | ||
89 | for a required id. This feature can also be used for the | ||
90 | purpose to make corre- spondence of fonts in different | ||
91 | categories. | ||
92 | |||
93 | |||
94 | __Category__ represents a type of fonts. Generally | ||
95 | configura- tion for fonts that belong to the same category | ||
96 | goes the same way, so it benefits the application's | ||
97 | configuration script. | ||
98 | |||
99 | |||
100 | __Hints__ represent essential font information and | ||
101 | typeface information of the font. They consist of some | ||
102 | !HintTypes and their values. They can be specified from | ||
103 | command line options of defoma-font, or through a | ||
104 | __hintfile__. | ||
105 | |||
106 | |||
107 | __Hintfile__ describes one or more fonts and their hints | ||
108 | in a single file. It is supposed to be put under | ||
109 | /etc/defoma/hints as a conffile, so that users can modify | ||
110 | the hints. | ||
111 | Following is the example of hintfile. __defoma-hints__ is | ||
112 | a tool to help generating hints as well as hintfile, so you | ||
113 | do not have to create one from scratch. | ||
114 | |||
115 | |||
116 | category type1 | ||
117 | begin /usr/share/fonts/type1/foo.pfa | ||
118 | !FontName = Helvetica | ||
119 | Charset = ISO8859-1 | ||
120 | Family = Helvetica | ||
121 | Weight = Medium | ||
122 | Shape = Upright !NoSerif | ||
123 | !GeneralFamily = !SansSerif | ||
124 | X-!FontName = -urw-helvetica-medium-r-noraml--0-0-0-0-p-iso8859-1 | ||
125 | end | ||
126 | begin /usr/share/fonts/type1/foob.pfa | ||
127 | !FontName = Helvetica-Bold | ||
128 | Charset = ISO8859-1 | ||

134 | end | ||
