+@RET@ FcChar8 *
+@FUNC@ FcPatternFormat
+@TYPE1@ FcPattern * @ARG1@ pat
+@TYPE2@ const FcChar8 * @ARG2@ format
+@PURPOSE@ Format a pattern into a string according to a format specifier
+@DESC@
+
+Converts given pattern <parameter>pat</parameter> into text described by
+the format specifier <parameter>format</parameter>.
+The return value refers to newly allocated memory which should be freed by the
+caller using free(), or NULL if <parameter>format</parameter> is invalid.
+
+</para><para>
+
+The format is loosely modeled after printf-style format string.
+The format string is composed of zero or more directives: ordinary
+characters (not "%"), which are copied unchanged to the output stream;
+and tags which are interpreted to construct text from the pattern in a
+variety of ways (explained below).
+Special characters can be escaped
+using backslash. C-string style special characters like \n and \r are
+also supported (this is useful when the format string is not a C string
+literal).
+It is advisable to always escape curly braces that
+are meant to be copied to the output as ordinary characters.
+
+</para><para>
+
+Each tag is introduced by the character "%",
+followed by an optional minimum field width,
+followed by tag contents in curly braces ({}).
+If the minimum field width value is provided the tag
+will be expanded and the result padded to achieve the minimum width.
+If the minimum field width is positive, the padding will right-align
+the text. Negative field width will left-align.
+The rest of this section describes various supported tag contents
+and their expansion.
+
+</para><para>
+
+A <firstterm>simple</firstterm> tag
+is one where the content is an identifier. When simple
+tags are expanded, the named identifier will be looked up in
+<parameter>pattern</parameter> and the resulting list of values returned,
+joined together using comma. For example, to print the family name and style of the
+pattern, use the format "%{family} %{style}\n". To extend the family column
+to forty characters use "%-40{family}%{style}\n".
+
+</para><para>
+
+Simple tags expand to list of all values for an element. To only choose
+one of the values, one can index using the syntax "%{elt[idx]}". For example,
+to get the first family name only, use "%{family[0]}".
+
+</para><para>
+
+If a simple tag ends with "=" and the element is found in the pattern, the
+name of the element followed by "=" will be output before the list of values.
+For example, "%{weight=}" may expand to the string "weight=80". Or to the empty
+string if <parameter>pattern</parameter> does not have weight set.
+
+</para><para>
+
+If a simple tag starts with ":" and the element is found in the pattern, ":"
+will be printed first. For example, combining this with the =, the format
+"%{:weight=}" may expand to ":weight=80" or to the empty string
+if <parameter>pattern</parameter> does not have weight set.
+
+</para><para>
+
+If a simple tag contains the string ":-", the rest of the the tag contents
+will be used as a default string. The default string is output if the element
+is not found in the pattern. For example, the format
+"%{:weight=:-123}" may expand to ":weight=80" or to the string
+":weight=123" if <parameter>pattern</parameter> does not have weight set.
+
+</para><para>
+
+A <firstterm>count</firstterm> tag
+is one that starts with the character "#" followed by an element
+name, and expands to the number of values for the element in the pattern.
+For example, "%{#family}" expands to the number of family names
+<parameter>pattern</parameter> has set, which may be zero.
+
+</para><para>
+
+A <firstterm>sub-expression</firstterm> tag
+is one that expands a sub-expression. The tag contents
+are the sub-expression to expand placed inside another set of curly braces.
+Sub-expression tags are useful for aligning an entire sub-expression, or to
+apply converters (explained later) to the entire sub-expression output.
+For example, the format "%40{{%{family} %{style}}}" expands the sub-expression
+to construct the family name followed by the style, then takes the entire
+string and pads it on the left to be at least forty characters.
+
+</para><para>
+
+A <firstterm>filter-out</firstterm> tag
+is one starting with the character "-" followed by a
+comma-separated list of element names, followed by a sub-expression enclosed
+in curly braces. The sub-expression will be expanded but with a pattern that
+has the listed elements removed from it.
+For example, the format "%{-size,pixelsize{sub-expr}}" will expand "sub-expr"
+with <parameter>pattern</parameter> sans the size and pixelsize elements.
+
+</para><para>
+
+A <firstterm>filter-in</firstterm> tag
+is one starting with the character "+" followed by a
+comma-separated list of element names, followed by a sub-expression enclosed
+in curly braces. The sub-expression will be expanded but with a pattern that
+only has the listed elements from the surrounding pattern.
+For example, the format "%{+family,familylang{sub-expr}}" will expand "sub-expr"
+with a sub-pattern consisting only the family and family lang elements of
+<parameter>pattern</parameter>.
+
+</para><para>
+
+A <firstterm>conditional</firstterm> tag
+is one starting with the character "?" followed by a
+comma-separated list of element conditions, followed by two sub-expression
+enclosed in curly braces. An element condition can be an element name,
+in which case it tests whether the element is defined in pattern, or
+the character "!" followed by an element name, in which case the test
+is negated. The conditional passes if all the element conditions pass.
+The tag expands the first sub-expression if the conditional passes, and
+expands the second sub-expression otherwise.
+For example, the format "%{?size,dpi,!pixelsize{pass}{fail}}" will expand
+to "pass" if <parameter>pattern</parameter> has size and dpi elements but
+no pixelsize element, and to "fail" otherwise.
+
+</para><para>
+
+An <firstterm>enumerate</firstterm> tag
+is one starting with the string "[]" followed by a
+comma-separated list of element names, followed by a sub-expression enclosed
+in curly braces. The list of values for the named elements are walked in
+parallel and the sub-expression expanded each time with a pattern just having
+a single value for those elements, starting from the first value and
+continuing as long as any of those elements has a value.
+For example, the format "%{[]family,familylang{%{family} (%{familylang})\n}}"
+will expand the pattern "%{family} (%{familylang})\n" with a pattern
+having only the first value of the family and familylang elements, then expands
+it with the second values, then the third, etc.
+
+</para><para>
+
+As a special case, if an enumerate tag has only one element, and that element
+has only one value in the pattern, and that value is of type FcLangSet, the
+individual languages in the language set are enumerated.
+
+</para><para>
+
+A <firstterm>builtin</firstterm> tag
+is one starting with the character "=" followed by a builtin
+name. The following builtins are defined:
+
+<variablelist>
+
+<varlistentry><term>
+unparse
+</term><listitem><para>
+Expands to the result of calling FcNameUnparse() on the pattern.
+</para></listitem></varlistentry>
+
+<varlistentry><term>
+fcmatch
+</term><listitem><para>
+Expands to the output of the default output format of the fc-match

+
+<varlistentry><term>
+fclist
+</term><listitem><para>
+Expands to the output of the default output format of the fc-list
+command on the pattern, without the final newline.
+</para></listitem></varlistentry>
+
+<varlistentry><term>
+pkgkit
+</term><listitem><para>
+Expands to the list of PackageKit font() tags for the pattern.
+Currently this includes tags for each family name, and each language
+from the pattern, enumerated and sanitized into a set of tags terminated
+by newline. Package management systems can use these tags to tag their
+packages accordingly.
+</para></listitem></varlistentry>
+
+</variablelist>
+
+For example, the format "%{+family,style{%{=unparse}}}\n" will expand
+to an unparsed name containing only the family and style element values
+from <parameter>pattern</parameter>.
+
+</para><para>
+
+The contents of any tag can be followed by a set of zero or more
+<firstterm>converter</firstterm>s. A converter is specified by the
+character "|" followed by the converter name and arguments. The
+following converters are defined:
+
+<variablelist>

+@PURPOSE@ Create patterns from arguments
+@DESC@
+Builds a pattern using a list of objects, types and values. Each
+value to be entered in the pattern is specified with three arguments:
+</para>
+<orderedlist>
+<listitem><para>
+Object name, a string describing the property to be added.
+</para></listitem><listitem><para>
+Object type, one of the FcType enumerated values
+</para></listitem><listitem><para>
+Value, not an FcValue, but the raw type as passed to any of the
+FcPatternAdd<type> functions. Must match the type of the second
+argument.
+</para></listitem>
+</orderedlist>
+<para>
+The argument list is terminated by a null object name, no object type nor
+value need be passed for this. The values are added to `pattern', if
+`pattern' is null, a new pattern is created. In either case, the pattern is
+returned. Example
+</para>
+<programlisting>
+pattern = FcPatternBuild (0, FC_FAMILY, FcTypeString, "Times", (char *) 0);
+</programlisting>
+<para>
+FcPatternVaBuild is used when the arguments are already in the form of a
+varargs value. FcPatternVapBuild is a macro version of FcPatternVaBuild
+which returns its result directly in the <parameter>result</parameter>
+variable.

From an external perspective, configuration of the -library consists of generating a valid XML tree and feeding that to -FcConfigParse. The only other mechanism provided to applications for -changing the running configuration is to add fonts and directories to the -list of application-provided font files. - </para><para> -The intent is to make font configurations relatively static, and shared by -as many applications as possible. It is hoped that this will lead to more -stable font selection when passing names from one application to another. -XML was chosen as a configuration file format because it provides a format -which is easy for external agents to edit while retaining the correct -structure and syntax. - </para><para> -Font configuration is separate from font matching; applications needing to -do their own matching can access the available fonts from the library and -perform private matching. The intent is to permit applications to pick and -choose appropriate functionality from the library instead of forcing them to -choose between this library and a private configuration mechanism. The hope -is that this will ensure that configuration of fonts for all applications -can be centralized in one place. Centralizing font configuration will -simplify and regularize font installation and customization. - </para> - </sect2> - <sect2> - <title>FONT PROPERTIES</title> - <para> -While font patterns may contain essentially any properties, there are some -well known properties with associated types.

+<sect1><title>DESCRIPTION</title>
+ <para>
+Fontconfig is a library designed to provide system-wide font configuration,
+customization and application access.
+ </para>
+</sect1>
+<sect1><title>FUNCTIONAL OVERVIEW</title>
+ <para>
+Fontconfig contains two essential modules, the configuration module which
+builds an internal configuration from XML files and the matching module
+which accepts font patterns and returns the nearest matching font.
+ </para>
+ <sect2><title>FONT CONFIGURATION</title>
+ <para>
+The configuration module consists of the FcConfig datatype, libexpat and
+FcConfigParse which walks over an XML tree and amends a configuration with
+data found within. From an external perspective, configuration of the
+library consists of generating a valid XML tree and feeding that to
+FcConfigParse. The only other mechanism provided to applications for
+changing the running configuration is to add fonts and directories to the
+list of application-provided font files.
+ </para><para>
+The intent is to make font configurations relatively static, and shared by
+as many applications as possible. It is hoped that this will lead to more
+stable font selection when passing names from one application to another.
+XML was chosen as a configuration file format because it provides a format
+which is easy for external agents to edit while retaining the correct
+structure and syntax.
+ </para><para>
+Font configuration is separate from font matching; applications needing to
+do their own matching can access the available fonts from the library and
+perform private matching. The intent is to permit applications to pick and
+choose appropriate functionality from the library instead of forcing them to
+choose between this library and a private configuration mechanism. The hope
+is that this will ensure that configuration of fonts for all applications
+can be centralized in one place. Centralizing font configuration will
+simplify and regularize font installation and customization.
+ </para>
+ </sect2>
+ <sect2>
+ <title>FONT PROPERTIES</title>
+ <para>
+While font patterns may contain essentially any properties, there are some
+well known properties with associated types. Fontconfig uses some of these
+properties for font matching and font completion. Others are provided as a
+convenience for the application's rendering mechanism.
+ </para>

+ </sect2>
+</sect1>
+<sect1><title>Datatypes</title>
+ <para>
+Fontconfig uses abstract data types to hide internal implementation details
+for most data structures. A few structures are exposed where appropriate.
+ </para>
+ <sect2><title>FcChar8, FcChar16, FcChar32, FcBool</title>
+ <para>
+These are primitive data types; the FcChar* types hold precisely the number
+of bits stated (if supported by the C implementation). FcBool holds
+one of two C preprocessor symbols: FcFalse or FcTrue.
+ </para>
+ </sect2>
+ <sect2><title>FcMatrix</title>
+ <para>
+An FcMatrix holds an affine transformation, usually used to reshape glyphs.
+A small set of matrix operations are provided to manipulate these.
+ <programlisting>
+ typedef struct _FcMatrix {
+ double xx, xy, yx, yy;
+ } FcMatrix;
+ </programlisting>
+ </para>
+ </sect2>
+ <sect2><title>FcCharSet</title>
+ <para>
+An FcCharSet is an abstract type that holds the set of encoded Unicode chars
+in a font. Operations to build and compare these sets are provided.
+ </para>
+ </sect2>
+ <sect2><title>FcLangSet</title>
+ <para>
+An FcLangSet is an abstract type that holds the set of languages supported
+by a font. Operations to build and compare these sets are provided. These
+are computed for a font based on orthographic information built into the
+fontconfig library. Fontconfig has orthographies for all of the ISO 639-1
+languages except for MS, NA, PA, PS, QU, RN, RW, SD, SG, SN, SU and ZA. If
+you have orthographic information for any of these languages, please submit
+them.
+ </para>
+ </sect2>
+ <sect2><title>FcLangResult</title>
+ <para>
+An FcLangResult is an enumeration used to return the results of comparing
+two language strings or FcLangSet objects. FcLangEqual means the
+objects match language and territory. FcLangDifferentTerritory means
+the objects match in language but differ in territory.
+FcLangDifferentLang means the objects differ in language.
+ </para>
+ </sect2>
+ <sect2><title>FcType</title>
+ <para>
+Tags the kind of data stored in an FcValue.
+ </para>
+ </sect2>
+ <sect2><title>FcValue</title>
+ <para>
+An FcValue object holds a single value with one of a number of different
+types. The 'type' tag indicates which member is valid.
+ <programlisting>
+ typedef struct _FcValue {
+ FcType type;
+ union {
+ const FcChar8 *s;
+ int i;
+ FcBool b;
+ double d;
+ const FcMatrix *m;
+ const FcCharSet *c;
+ void *f;
+ const FcLangSet *l;
+ } u;
+ } FcValue;
+ </programlisting>
+ <programlisting>
+ FcValue Members
+
+ Type Union member Datatype
+ --------------------------------
+ FcTypeVoid (none) (none)
+ FcTypeInteger i int
+ FcTypeDouble d double
+ FcTypeString s FcChar8 *
+ FcTypeBool b b
+ FcTypeMatrix m FcMatrix *
+ FcTypeCharSet c FcCharSet *
+ FcTypeFTFace f void * (FT_Face)
+ FcTypeLangSet l FcLangSet *
+ </programlisting>
+ </para>
+ </sect2>
+ <sect2><title>FcPattern</title>
+ <para>
+holds a set of names with associated value lists; each name refers to a
+property of a font. FcPatterns are used as inputs to the matching code as
+well as holding information about specific fonts. Each property can hold
+one or more values; conventionally all of the same type, although the
+interface doesn't demand that.
+ </para>
+ </sect2>
+ <sect2><title>FcFontSet</title>
+ <para>
+ <programlisting>
+ typedef struct _FcFontSet {
+ int nfont;
+ int sfont;
+ FcPattern **fonts;
+ } FcFontSet;
+ </programlisting>
+An FcFontSet contains a list of FcPatterns. Internally fontconfig uses this
+data structure to hold sets of fonts. Externally, fontconfig returns the
+results of listing fonts in this format. 'nfont' holds the number of
+patterns in the 'fonts' array; 'sfont' is used to indicate the size of that
+array.
+ </para>
+ </sect2>
+ <sect2><title>FcStrSet, FcStrList</title>
+ <para>
+FcStrSet holds a list of strings that can be appended to and enumerated.
+Its unique characteristic is that the enumeration works even while strings
+are appended during enumeration. FcStrList is used during enumeration to
+safely and correctly walk the list of strings even while that list is edited
+in the middle of enumeration.
+ </para>
+ </sect2>
+ <sect2><title>FcObjectSet</title>
+ <para>
+ <programlisting>
+ typedef struct _FcObjectSet {
+ int nobject;
+ int sobject;
+ const char **objects;
+ } FcObjectSet;
+ </programlisting>
+holds a set of names and is used to specify which fields from fonts are
+placed in the the list of returned patterns when listing fonts.
+ </para>
+ </sect2>
+ <sect2><title>FcObjectType</title>
+ <para>
+ <programlisting>
+ typedef struct _FcObjectType {
+ const char *object;
+ FcType type;
+ } FcObjectType;
+ </programlisting>
+marks the type of a pattern element generated when parsing font names.
+Applications can add new object types so that font names may contain the new
+elements.
+ </para>
+ </sect2>
+ <sect2><title>FcConstant</title>
+ <para>
+ <programlisting>
+ typedef struct _FcConstant {
+ const FcChar8 *name;
+ const char *object;
+ int value;
+ } FcConstant;
+ </programlisting>
+Provides for symbolic constants for new pattern elements. When 'name' is
+seen in a font name, an 'object' element is created with value 'value'.
+ </para>
+ </sect2>
+ <sect2><title>FcBlanks</title>
+ <para>
+holds a list of Unicode chars which are expected to be blank; unexpectedly
+blank chars are assumed to be invalid and are elided from the charset
+associated with the font.
+ </para>
+ </sect2>
+ <sect2><title>FcFileCache</title>
+ <para>
+holds the per-user cache information for use while loading the font
+database. This is built automatically for the current configuration when
+that is loaded. Applications must always pass '0' when one is requested.
+ </para>
+ </sect2>
+ <sect2><title>FcConfig</title>
+ <para>
+holds a complete configuration of the library; there is one default
+configuration, other can be constructed from XML data structures. All
+public entry points that need global data can take an optional FcConfig*
+argument; passing 0 uses the default configuration. FcConfig objects hold two
+sets of fonts, the first contains those specified by the configuration, the
+second set holds those added by the application at run-time. Interfaces
+that need to reference a particular set use one of the FcSetName enumerated
+values.
+ </para>
+ </sect2>
+ <sect2><title>FcSetName</title>
+ <para>
+Specifies one of the two sets of fonts available in a configuration;
+FcSetSystem for those fonts specified in the configuration and
+FcSetApplication which holds fonts provided by the application.
+ </para>
+ </sect2>
+ <sect2><title>FcResult</title>
+ <para>
+Used as a return type for functions manipulating FcPattern objects.
+ <programlisting>
+ FcResult Values
+ Result Code Meaning
+ -----------------------------------------------------------
+ FcResultMatch Object exists with the specified ID
+ FcResultNoMatch Object doesn't exist at all
+ FcResultTypeMismatch Object exists, but the type doesn't match
+ FcResultNoId Object exists, but has fewer values
+ than specified
+ FcResultOutOfMemory malloc failed
+ </programlisting>
+ </para>
+ </sect2>
+ <sect2><title>FcAtomic</title>
+ <para>
+Used for locking access to configuration files. Provides a safe way to update
+configuration files.
+ </para>
+ </sect2>
+ <sect2><title>FcCache</title>
+ <para>
+Holds information about the fonts contained in a single directory. Normal
+applications need not worry about this as caches for font access are
+automatically managed by the library. Applications dealing with cache
+management may want to use some of these objects in their work, however the
+included 'fc-cache' program generally suffices for all of that.
+ </para>
+ </sect2>
+</sect1>
+<sect1><title>FUNCTIONS</title>
+ <para>
+These are grouped by functionality, often using the main data type being
+manipulated.
+ </para>
+ <sect2><title>Initialization</title>
+ <para>
+These functions provide some control over how the library is initialized.
+ </para>
+ &fcinit;
+ </sect2>
+ <sect2><title>FcPattern</title>
+ <para>
+An FcPattern is an opaque type that holds both patterns to match against the
+available fonts, as well as the information about each font.
+ </para>
+ &fcpattern;
+ &fcformat;
+ </sect2>
+ <sect2><title>FcFontSet</title>
+ <para>
+An FcFontSet simply holds a list of patterns; these are used to return the
+results of listing available fonts.
+ </para>
+ &fcfontset;
+ </sect2>
+ <sect2><title>FcObjectSet</title>
+ <para>
+An FcObjectSet holds a list of pattern property names; it is used to

+FcFontList.
+ </para>
+ &fcobjectset;
+ </sect2>
+ <sect2><title>FreeType specific functions</title>
+ <para>
+While the fontconfig library doesn't insist that FreeType be used as the
+rasterization mechanism for fonts, it does provide some convenience
+functions.
+ </para>
+ &fcfreetype;
+ </sect2>
+ <sect2><title>FcValue</title>
+ <para>
+FcValue is a structure containing a type tag and a union of all possible
+datatypes. The tag is an enum of type
+<emphasis>FcType</emphasis>
+and is intended to provide a measure of run-time
+typechecking, although that depends on careful programming.
+ </para>
+ &fcvalue;
+ </sect2>
+ <sect2><title>FcCharSet</title>
+ <para>
+An FcCharSet is a boolean array indicating a set of Unicode chars. Those
+associated with a font are marked constant and cannot be edited.
+FcCharSets may be reference counted internally to reduce memory consumption;
+this may be visible to applications as the result of FcCharSetCopy may
+return it's argument, and that CharSet may remain unmodifiable.

+ <para>
+An FcLangSet is a set of language names (each of which include language and

From an external perspective, configuration of the -library consists of generating a valid XML tree and feeding that to -FcConfigParse. The only other mechanism provided to applications for -changing the running configuration is to add fonts and directories to the -list of application-provided font files. - </para><para> -The intent is to make font configurations relatively static, and shared by -as many applications as possible. It is hoped that this will lead to more -stable font selection when passing names from one application to another. -XML was chosen as a configuration file format because it provides a format -which is easy for external agents to edit while retaining the correct -structure and syntax. - </para><para> -Font configuration is separate from font matching; applications needing to -do their own matching can access the available fonts from the library and -perform private matching. The intent is to permit applications to pick and -choose appropriate functionality from the library instead of forcing them to -choose between this library and a private configuration mechanism. The hope -is that this will ensure that configuration of fonts for all applications -can be centralized in one place. Centralizing font configuration will -simplify and regularize font installation and customization. - </para> - </refsect2> - <refsect2> - <title>Font Properties</title> - <para> -While font patterns may contain essentially any properties, there are some -well known properties with associated types. Fontconfig uses some of these -properties for font matching and font completion. Others are provided as a -convenience for the applications' rendering mechanism. - </para> - <programlisting> - Property Type Description - -------------------------------------------------------------- - family String Font family names - familylang String Languages corresponding to each family - style String Font style.

The closest matching -font is selected. This ensures that a font will always be returned, but -doesn't ensure that it is anything like the requested pattern. - </para><para> -Font matching starts with an application constructed pattern. The desired -attributes of the resulting font are collected together in a pattern. Each -property of the pattern can contain one or more values; these are listed in -priority order; matches earlier in the list are considered "closer" than -matches later in the list. - </para><para> -The initial pattern is modified by applying the list of editing instructions -specific to patterns found in the configuration; each consists of a match -predicate and a set of editing operations. They are executed in the order -they appeared in the configuration. Each match causes the associated -sequence of editing operations to be applied. - </para><para> -After the pattern has been edited, a sequence of default substitutions are -performed to canonicalize the set of available properties; this avoids the -need for the lower layers to constantly provide default values for various -font properties during rendering. - </para><para> -The canonical font pattern is finally matched against all available fonts. -The distance from the pattern to the font is measured for each of several -properties: foundry, charset, family, lang, spacing, pixelsize, style, -slant, weight, antialias, rasterizer and outline. This list is in priority -order -- results of comparing earlier elements of this list weigh more -heavily than later elements. - </para><para> -There is one special case to this rule; family names are split into two -bindings; strong and weak. Strong family names are given greater precedence -in the match than lang elements while weak family names are given lower -precedence than lang elements. This permits the document language to drive -font selection when any document specified font is unavailable. - </para><para> -The pattern representing that font is augmented to include any properties -found in the pattern but not found in the font itself; this permits the -application to pass rendering instructions or any other data through the -matching system. Finally, the list of editing instructions specific to -fonts found in the configuration are applied to the pattern. This modified -pattern is returned to the application. - </para><para> -The return value contains sufficient information to locate and rasterize the -font, including the file name, pixel size and other rendering data. As -none of the information involved pertains to the FreeType library, -applications are free to use any rasterization engine or even to take -the identified font file and access it directly. - </para><para> -The match/edit sequences in the configuration are performed in two passes -because there are essentially two different operations necessary -- the -first is to modify how fonts are selected; aliasing families and adding -suitable defaults. The second is to modify how the selected fonts are -rasterized. Those must apply to the selected font, not the original pattern -as false matches will often occur. - </para> - </refsect2> - <refsect2><title>Font Names</title> - <para> -Fontconfig provides a textual representation for patterns that the library -can both accept and generate. The representation is in three parts, first a -list of family names, second a list of point sizes and finally a list of -additional properties: - </para> - <programlisting> - <families>-<point sizes>:<name1>=<values1>:<name2>=<values2>... - </programlisting> - <para> -Values in a list are separated with commas. The name needn't include either -families or point sizes; they can be elided. In addition, there are -symbolic constants that simultaneously indicate both a name and a value. -Here are some examples: - </para> - <programlisting> - Name Meaning - ---------------------------------------------------------- - Times-12 12 point Times Roman - Times-12:bold 12 point Times Bold - Courier:italic Courier Italic in the default size - Monospace:matrix=1 .1 0 1 The users preferred monospace font - with artificial obliquing - </programlisting> - <para> -The '\', '-', ':' and ',' characters in family names must be preceded by a -'\' character to avoid having them misinterpreted. Similarly, values -containing '\', '=', '_', ':' and ',' must also have them preceded by a -'\' character. The '\' characters are stripped out of the family name and -values as the font name is read. - </para> - </refsect2> -</refsect1> -<refsect1><title>Debugging Applications</title> - <para> -To help diagnose font and applications problems, fontconfig is built with a -large amount of internal debugging left enabled. It is controlled by means -of the FC_DEBUG environment variable. The value of this variable is -interpreted as a number, and each bit within that value controls different -debugging messages. - </para> - <programlisting> - Name Value Meaning - --------------------------------------------------------- - MATCH 1 Brief information about font matching - MATCHV 2 Extensive font matching information - EDIT 4 Monitor match/test/edit execution - FONTSET 8 Track loading of font information at startup - CACHE 16 Watch cache files being written - CACHEV 32 Extensive cache file writing information - PARSE 64 (no longer in use) - SCAN 128 Watch font files being scanned to build caches - SCANV 256 Verbose font file scanning information - MEMORY 512 Monitor fontconfig memory usage - CONFIG 1024 Monitor which config files are loaded - LANGSET 2048 Dump char sets used to construct lang values - OBJTYPES 4096 Display message when value typechecks fail - </programlisting> - <para> -Add the value of the desired debug levels together and assign that (in -base 10) to the FC_DEBUG environment variable before running the -application. Output from these statements is sent to stdout. - </para> -</refsect1> -<refsect1><title>Lang Tags</title> - <para> -Each font in the database contains a list of languages it supports. This is -computed by comparing the Unicode coverage of the font with the orthography -of each language. Languages are tagged using an RFC-3066 compatible naming -and occur in two parts -- the ISO 639 language tag followed a hyphen and then -by the ISO 3166 country code. The hyphen and country code may be elided. - </para><para> -Fontconfig has orthographies for several languages built into the library. -No provision has been made for adding new ones aside from rebuilding the -library. It currently supports 122 of the 139 languages named in ISO 639-1, -141 of the languages with two-letter codes from ISO 639-2 and another 30 -languages with only three-letter codes. Languages with both two and three -letter codes are provided with only the two letter code. - </para><para> -For languages used in multiple territories with radically different -character sets, fontconfig includes per-territory orthographies. This -includes Azerbaijani, Kurdish, Pashto, Tigrinya and Chinese. - </para> -</refsect1> -<refsect1><title>Configuration File Format</title> - <para> -Configuration files for fontconfig are stored in XML format; this -format makes external configuration tools easier to write and ensures that -they will generate syntactically correct configuration files. As XML -files are plain text, they can also be manipulated by the expert user using -a text editor. - </para><para> -The fontconfig document type definition resides in the external entity -"fonts.dtd"; this is normally stored in the default font configuration -directory (&confdir;).

If it starts with '~', it refers to a file in the users -home directory. This file is used to hold information about fonts that -isn't present in the per-directory cache files. It is automatically -maintained by the fontconfig library. The default for this file -is ``~/.fonts.cache-<literal><version></literal>'', where <literal><version></literal> is the font configuration -file version number (currently 2). - </para></refsect2> - <refsect2><title><literal><include ignore_missing="no"></literal></title><para> -This element contains the name of an additional configuration file or -directory. If a directory, every file within that directory starting with an -ASCII digit (U+0030 - U+0039) and ending with the string ``.conf'' will be processed in sorted order.

It holds acceptfont and rejectfont elements. - </para></refsect2> - <refsect2><title><literal><acceptfont></literal></title><para> -Fonts matched by an acceptfont element are "whitelisted"; such fonts are -explicitly included in the set of fonts used to resolve list and match -requests; including them in this list protects them from being "blacklisted" -by a rejectfont element. Acceptfont elements include glob and pattern -elements which are used to match fonts. - </para></refsect2> - <refsect2><title><literal><rejectfont></literal></title><para> -Fonts matched by an rejectfont element are "blacklisted"; such fonts are -excluded from the set of fonts used to resolve list and match requests as if -they didn't exist in the system. Rejectfont elements include glob and -pattern elements which are used to match fonts. - </para></refsect2> - <refsect2><title><literal><glob></literal></title><para> -Glob elements hold shell-style filename matching patterns (including ? and -*) which match fonts based on their complete pathnames. This can be used to -exclude a set of directories (/usr/share/fonts/uglyfont*), or particular -font file types (*.pcf.gz), but the latter mechanism relies rather heavily -on filenaming conventions which can't be relied upon. Note that globs -only apply to directories, not to individual fonts. - </para></refsect2> - <refsect2><title><literal><pattern></literal></title><para> -Pattern elements perform list-style matching on incoming fonts; that is, -they hold a list of elements and associated values. If all of those -elements have a matching value, then the pattern matches the font. This can -be used to select fonts based on attributes of the font (scalable, bold, -etc), which is a more reliable mechanism than using file extensions. -Pattern elements include patelt elements. - </para></refsect2> - <refsect2><title><literal><patelt name="property"></literal></title><para> -Patelt elements hold a single pattern element and list of values. They must -have a 'name' attribute which indicates the pattern element name.

Patterns which match all of the -tests are subjected to all the edits. If 'target' is set to "font" instead -of the default "pattern", then this element applies to the font name -resulting from a match rather than a font pattern to be matched. If 'target' -is set to "scan", then this element applies when the font is scanned to -build the fontconfig database. - </para></refsect2> - <refsect2><title><literal><test qual="any" name="property" target="default" compare="eq"></literal></title><para> -This element contains a single value which is compared with the target -('pattern', 'font', 'scan' or 'default') property "property" (substitute any of the property names seen -above). 'compare' can be one of "eq", "not_eq", "less", "less_eq", "more", or -"more_eq". 'qual' may either be the default, "any", in which case the match -succeeds if any value associated with the property matches the test value, or -"all", in which case all of the values associated with the property must -match the test value. When used in a <match target="font"> element, -the target= attribute in the <test> element selects between matching -the original pattern or the font. "default" selects whichever target the -outer <match> element has selected. - </para></refsect2> - <refsect2><title><literal><edit name="property" mode="assign" binding="weak"></literal></title><para> -This element contains a list of expression elements (any of the value or -operator elements). The expression elements are evaluated at run-time and -modify the property "property". The modification depends on whether -"property" was matched by one of the associated <literal><test></literal> elements, if so, the -modification may affect the first matched value. Any values inserted into -the property are given the indicated binding ("strong", "weak" or "same") -with "same" binding using the value from the matched pattern element. -'mode' is one of: - <programlisting> - Mode With Match Without Match - --------------------------------------------------------------------- - "assign" Replace matching value Replace all values - "assign_replace" Replace all values Replace all values - "prepend" Insert before matching Insert at head of list - "prepend_first" Insert at head of list Insert at head of list - "append" Append after matching Append at end of list - "append_last" Append at end of list Append at end of list - </programlisting> - </para></refsect2> - <refsect2><title><literal><int></literal>, <literal><double></literal>, <literal><string></literal>, <literal><bool></literal></title><para> -These elements hold a single value of the indicated type. <literal><bool></literal> -elements hold either true or false.

+ <para>
+Fontconfig is a library designed to provide system-wide font configuration,
+customization and application access.
+ </para>
+</refsect1>
+<refsect1><title>Functional Overview</title>
+ <para>
+Fontconfig contains two essential modules, the configuration module which
+builds an internal configuration from XML files and the matching module
+which accepts font patterns and returns the nearest matching font.
+ </para>
+ <refsect2><title>Font Configuration</title>
+ <para>
+The configuration module consists of the FcConfig datatype, libexpat and
+FcConfigParse which walks over an XML tree and amends a configuration with
+data found within. From an external perspective, configuration of the
+library consists of generating a valid XML tree and feeding that to
+FcConfigParse. The only other mechanism provided to applications for
+changing the running configuration is to add fonts and directories to the
+list of application-provided font files.
+ </para><para>
+The intent is to make font configurations relatively static, and shared by
+as many applications as possible. It is hoped that this will lead to more
+stable font selection when passing names from one application to another.
+XML was chosen as a configuration file format because it provides a format
+which is easy for external agents to edit while retaining the correct
+structure and syntax.
+ </para><para>
+Font configuration is separate from font matching; applications needing to
+do their own matching can access the available fonts from the library and
+perform private matching. The intent is to permit applications to pick and
+choose appropriate functionality from the library instead of forcing them to
+choose between this library and a private configuration mechanism. The hope
+is that this will ensure that configuration of fonts for all applications
+can be centralized in one place. Centralizing font configuration will
+simplify and regularize font installation and customization.
+ </para>
+ </refsect2>
+ <refsect2>
+ <title>Font Properties</title>
+ <para>
+While font patterns may contain essentially any properties, there are some
+well known properties with associated types. Fontconfig uses some of these
+properties for font matching and font completion. Others are provided as a
+convenience for the applications' rendering mechanism.
+ </para>

+ <refsect2>
+ <title>Font Matching</title>
+ <para>
+Fontconfig performs matching by measuring the distance from a provided
+pattern to all of the available fonts in the system. The closest matching
+font is selected. This ensures that a font will always be returned, but
+doesn't ensure that it is anything like the requested pattern.
+ </para><para>
+Font matching starts with an application constructed pattern. The desired
+attributes of the resulting font are collected together in a pattern. Each
+property of the pattern can contain one or more values; these are listed in
+priority order; matches earlier in the list are considered "closer" than
+matches later in the list.
+ </para><para>
+The initial pattern is modified by applying the list of editing instructions
+specific to patterns found in the configuration; each consists of a match
+predicate and a set of editing operations. They are executed in the order
+they appeared in the configuration. Each match causes the associated
+sequence of editing operations to be applied.
+ </para><para>
+After the pattern has been edited, a sequence of default substitutions are
+performed to canonicalize the set of available properties; this avoids the
+need for the lower layers to constantly provide default values for various
+font properties during rendering.
+ </para><para>
+The canonical font pattern is finally matched against all available fonts.
+The distance from the pattern to the font is measured for each of several
+properties: foundry, charset, family, lang, spacing, pixelsize, style,
+slant, weight, antialias, rasterizer and outline. This list is in priority
+order -- results of comparing earlier elements of this list weigh more
+heavily than later elements.
+ </para><para>
+There is one special case to this rule; family names are split into two
+bindings; strong and weak. Strong family names are given greater precedence
+in the match than lang elements while weak family names are given lower
+precedence than lang elements. This permits the document language to drive
+font selection when any document specified font is unavailable.
+ </para><para>
+The pattern representing that font is augmented to include any properties
+found in the pattern but not found in the font itself; this permits the
+application to pass rendering instructions or any other data through the
+matching system. Finally, the list of editing instructions specific to
+fonts found in the configuration are applied to the pattern. This modified
+pattern is returned to the application.
+ </para><para>
+The return value contains sufficient information to locate and rasterize the
+font, including the file name, pixel size and other rendering data. As
+none of the information involved pertains to the FreeType library,
+applications are free to use any rasterization engine or even to take
+the identified font file and access it directly.
+ </para><para>
+The match/edit sequences in the configuration are performed in two passes
+because there are essentially two different operations necessary -- the
+first is to modify how fonts are selected; aliasing families and adding
+suitable defaults. The second is to modify how the selected fonts are
+rasterized. Those must apply to the selected font, not the original pattern
+as false matches will often occur.
+ </para>
+ </refsect2>
+ <refsect2><title>Font Names</title>
+ <para>
+Fontconfig provides a textual representation for patterns that the library
+can both accept and generate. The representation is in three parts, first a
+list of family names, second a list of point sizes and finally a list of
+additional properties:
+ </para>
+ <programlisting>
+ <families>-<point sizes>:<name1>=<values1>:<name2>=<values2>...
+ </programlisting>
+ <para>
+Values in a list are separated with commas. The name needn't include either
+families or point sizes; they can be elided. In addition, there are
+symbolic constants that simultaneously indicate both a name and a value.
+Here are some examples:
+ </para>
+ <programlisting>
+ Name Meaning
+ ----------------------------------------------------------
+ Times-12 12 point Times Roman
+ Times-12:bold 12 point Times Bold
+ Courier:italic Courier Italic in the default size
+ Monospace:matrix=1 .1 0 1 The users preferred monospace font
+ with artificial obliquing
+ </programlisting>
+ <para>
+The '\', '-', ':' and ',' characters in family names must be preceded by a
+'\' character to avoid having them misinterpreted. Similarly, values
+containing '\', '=', '_', ':' and ',' must also have them preceded by a
+'\' character. The '\' characters are stripped out of the family name and
+values as the font name is read.
+ </para>
+ </refsect2>
+</refsect1>
+<refsect1><title>Debugging Applications</title>
+ <para>
+To help diagnose font and applications problems, fontconfig is built with a
+large amount of internal debugging left enabled. It is controlled by means
+of the FC_DEBUG environment variable. The value of this variable is
+interpreted as a number, and each bit within that value controls different
+debugging messages.
+ </para>
+ <programlisting>
+ Name Value Meaning
+ ---------------------------------------------------------
+ MATCH 1 Brief information about font matching
+ MATCHV 2 Extensive font matching information
+ EDIT 4 Monitor match/test/edit execution
+ FONTSET 8 Track loading of font information at startup
+ CACHE 16 Watch cache files being written
+ CACHEV 32 Extensive cache file writing information
+ PARSE 64 (no longer in use)
+ SCAN 128 Watch font files being scanned to build caches
+ SCANV 256 Verbose font file scanning information
+ MEMORY 512 Monitor fontconfig memory usage
+ CONFIG 1024 Monitor which config files are loaded
+ LANGSET 2048 Dump char sets used to construct lang values
+ OBJTYPES 4096 Display message when value typechecks fail
+ </programlisting>
+ <para>
+Add the value of the desired debug levels together and assign that (in
+base 10) to the FC_DEBUG environment variable before running the
+application. Output from these statements is sent to stdout.
+ </para>
+</refsect1>
+<refsect1><title>Lang Tags</title>
+ <para>
+Each font in the database contains a list of languages it supports. This is
+computed by comparing the Unicode coverage of the font with the orthography
+of each language. Languages are tagged using an RFC-3066 compatible naming
+and occur in two parts -- the ISO 639 language tag followed a hyphen and then
+by the ISO 3166 country code. The hyphen and country code may be elided.
+ </para><para>
+Fontconfig has orthographies for several languages built into the library.
+No provision has been made for adding new ones aside from rebuilding the
+library. It currently supports 122 of the 139 languages named in ISO 639-1,
+141 of the languages with two-letter codes from ISO 639-2 and another 30
+languages with only three-letter codes. Languages with both two and three
+letter codes are provided with only the two letter code.
+ </para><para>
+For languages used in multiple territories with radically different
+character sets, fontconfig includes per-territory orthographies. This
+includes Azerbaijani, Kurdish, Pashto, Tigrinya and Chinese.
+ </para>
+</refsect1>
+<refsect1><title>Configuration File Format</title>
+ <para>
+Configuration files for fontconfig are stored in XML format; this
+format makes external configuration tools easier to write and ensures that
+they will generate syntactically correct configuration files. As XML
+files are plain text, they can also be manipulated by the expert user using
+a text editor.
+ </para><para>
+The fontconfig document type definition resides in the external entity
+"fonts.dtd"; this is normally stored in the default font configuration
+directory (&confdir;). Each configuration file should contain the
+following structure:
+ <programlisting>
+ <?xml version="1.0"?>
+ <!DOCTYPE fontconfig SYSTEM "fonts.dtd">
+ <fontconfig>
+ ...
+ </fontconfig>
+ </programlisting>
+ </para>
+<refsect2><title><literal><fontconfig></literal></title><para>
+This is the top level element for a font configuration and can contain
+<literal><dir></literal>, <literal><cache></literal>, <literal><include></literal>, <literal><match></literal> and <literal><alias></literal> elements in any order.
+ </para></refsect2>
+ <refsect2><title><literal><dir></literal></title><para>
+This element contains a directory name which will be scanned for font files
+to include in the set of available fonts.
+ </para></refsect2>
+ <refsect2><title><literal><cache></literal></title><para>
+This element contains a file name for the per-user cache of font
+information. If it starts with '~', it refers to a file in the users
+home directory. This file is used to hold information about fonts that
+isn't present in the per-directory cache files. It is automatically
+maintained by the fontconfig library. The default for this file
+is ``~/.fonts.cache-<literal><version></literal>'', where <literal><version></literal> is the font configuration
+file version number (currently 2).
+ </para></refsect2>
+ <refsect2><title><literal><include ignore_missing="no"></literal></title><para>
+This element contains the name of an additional configuration file or
+directory. If a directory, every file within that directory starting with an
+ASCII digit (U+0030 - U+0039) and ending with the string ``.conf'' will be processed in sorted order. When
+the XML datatype is traversed by FcConfigParse, the contents of the file(s)
+will also be incorporated into the configuration by passing the filename(s) to
+FcConfigLoadAndParse. If 'ignore_missing' is set to "yes" instead of the
+default "no", a missing file or directory will elicit no warning message from
+the library.
+ </para></refsect2>
+ <refsect2><title><literal><config></literal></title><para>
+This element provides a place to consolidate additional configuration
+information. <literal><config></literal> can contain <literal><blank></literal> and <literal><rescan></literal> elements in any
+order.
+ </para></refsect2>
+ <refsect2><title><literal><blank></literal></title><para>
+Fonts often include "broken" glyphs which appear in the encoding but are
+drawn as blanks on the screen. Within the <literal><blank></literal> element, place each
+Unicode characters which is supposed to be blank in an <literal><int></literal> element.
+Characters outside of this set which are drawn as blank will be elided from
+the set of characters supported by the font.
+ </para></refsect2>
+ <refsect2><title><literal><rescan></literal></title><para>
+The <literal><rescan></literal> element holds an <literal><int></literal> element which indicates the default
+interval between automatic checks for font configuration changes.
+Fontconfig will validate all of the configuration files and directories and
+automatically rebuild the internal datastructures when this interval passes.
+ </para></refsect2>
+ <refsect2><title><literal><selectfont></literal></title><para>
+This element is used to black/white list fonts from being listed or matched
+against. It holds acceptfont and rejectfont elements.
+ </para></refsect2>
+ <refsect2><title><literal><acceptfont></literal></title><para>
+Fonts matched by an acceptfont element are "whitelisted"; such fonts are
+explicitly included in the set of fonts used to resolve list and match
+requests; including them in this list protects them from being "blacklisted"
+by a rejectfont element. Acceptfont elements include glob and pattern
+elements which are used to match fonts.
+ </para></refsect2>
+ <refsect2><title><literal><rejectfont></literal></title><para>
+Fonts matched by an rejectfont element are "blacklisted"; such fonts are
+excluded from the set of fonts used to resolve list and match requests as if
+they didn't exist in the system. Rejectfont elements include glob and
+pattern elements which are used to match fonts.
+ </para></refsect2>
+ <refsect2><title><literal><glob></literal></title><para>
+Glob elements hold shell-style filename matching patterns (including ? and
+*) which match fonts based on their complete pathnames. This can be used to
+exclude a set of directories (/usr/share/fonts/uglyfont*), or particular
+font file types (*.pcf.gz), but the latter mechanism relies rather heavily
+on filenaming conventions which can't be relied upon. Note that globs
+only apply to directories, not to individual fonts.
+ </para></refsect2>
+ <refsect2><title><literal><pattern></literal></title><para>
+Pattern elements perform list-style matching on incoming fonts; that is,
+they hold a list of elements and associated values. If all of those
+elements have a matching value, then the pattern matches the font. This can
+be used to select fonts based on attributes of the font (scalable, bold,
+etc), which is a more reliable mechanism than using file extensions.
+Pattern elements include patelt elements.
+ </para></refsect2>
+ <refsect2><title><literal><patelt name="property"></literal></title><para>
+Patelt elements hold a single pattern element and list of values. They must
+have a 'name' attribute which indicates the pattern element name. Patelt
+elements include int, double, string, matrix, bool, charset and const
+elements.
+ </para></refsect2>
+ <refsect2><title><literal><match target="pattern"></literal></title><para>
+This element holds first a (possibly empty) list of <literal><test></literal> elements and then
+a (possibly empty) list of <literal><edit></literal> elements. Patterns which match all of the
+tests are subjected to all the edits. If 'target' is set to "font" instead
+of the default "pattern", then this element applies to the font name
+resulting from a match rather than a font pattern to be matched. If 'target'
+is set to "scan", then this element applies when the font is scanned to
+build the fontconfig database.
+ </para></refsect2>
+ <refsect2><title><literal><test qual="any" name="property" target="default" compare="eq"></literal></title><para>
+This element contains a single value which is compared with the target
+('pattern', 'font', 'scan' or 'default') property "property" (substitute any of the property names seen
+above). 'compare' can be one of "eq", "not_eq", "less", "less_eq", "more", or
+"more_eq". 'qual' may either be the default, "any", in which case the match
+succeeds if any value associated with the property matches the test value, or
+"all", in which case all of the values associated with the property must
+match the test value. When used in a <match target="font"> element,
+the target= attribute in the <test> element selects between matching
+the original pattern or the font. "default" selects whichever target the
+outer <match> element has selected.
+ </para></refsect2>
+ <refsect2><title><literal><edit name="property" mode="assign" binding="weak"></literal></title><para>
+This element contains a list of expression elements (any of the value or
+operator elements). The expression elements are evaluated at run-time and
+modify the property "property". The modification depends on whether
+"property" was matched by one of the associated <literal><test></literal> elements, if so, the
+modification may affect the first matched value. Any values inserted into
+the property are given the indicated binding ("strong", "weak" or "same")
+with "same" binding using the value from the matched pattern element.
+'mode' is one of:
+ <programlisting>

+ "assign" Replace matching value Replace all values
+ "assign_replace" Replace all values Replace all values
+ "prepend" Insert before matching Insert at head of list

+ </programlisting>
+ </para></refsect2>
+ <refsect2><title><literal><int></literal>, <literal><double></literal>, <literal><string></literal>, <literal><bool></literal></title><para>
+These elements hold a single value of the indicated type. <literal><bool></literal>
+elements hold either true or false. An important limitation exists in
+the parsing of floating point numbers -- fontconfig requires that
+the mantissa start with a digit, not a decimal point, so insert a leading
+zero for purely fractional values (e.g. use 0.5 instead of .5 and -0.5
+instead of -.5).
+ </para></refsect2>
