DESCRIPTION
Fontconfig is a library designed to provide system-wide font configuration, customization
and application access.
FUNCTIONAL OVERVIEW
Fontconfig contains two essential modules, the configuration module which builds an inter‐
nal configuration from XML files and the matching module which accepts font patterns and
returns the nearest matching font.
FONT CONFIGURATION
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 applica‐
tion-provided font files.
The intent is to make font configurations relatively static, and shared by as many appli‐
cations 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.
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 applica‐
tions can be centralized in one place. Centralizing font configuration will simplify and
regularize font installation and customization.
FONT PROPERTIES
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 match‐
ing and font completion. Others are provided as a convenience for the applications' ren‐
dering mechanism.

FONT MATCHING
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.
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.
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 edit‐
ing operations. They are executed in the order they appeared in the configuration. Each
match causes the associated sequence of editing operations to be applied.
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.
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.
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.
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.
The return value contains sufficient information to locate and rasterize the font, includ‐
ing 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.
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.
FONT NAMES
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:
<families>-<point sizes>:<name1>=<values1>:<name2>=<values2>...
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 simultane‐
ously indicate both a name and a value. Here are some examples:
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
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.
DEBUGGING APPLICATIONS
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.
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
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.
LANG TAGS
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. Lan‐
guages 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.
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.
For languages used in multiple territories with radically different character sets, font‐
config includes per-territory orthographies. This includes Azerbaijani, Kurdish, Pashto,
Tigrinya and Chinese.
CONFIGURATION FILE FORMAT
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 cor‐
rect configuration files. As XML files are plain text, they can also be manipulated by the
expert user using a text editor.
The fontconfig document type definition resides in the external entity "fonts.dtd"; this
is normally stored in the default font configuration directory (/etc/fonts). Each configu‐
ration file should contain the following structure:
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
...
</fontconfig>
<FONTCONFIG>
This is the top level element for a font configuration and can contain <dir>, <cachedir>,
<include>, <match> and <alias> elements in any order.
<DIR PREFIX="DEFAULT">
This element contains a directory name which will be scanned for font files to include in
the set of available fonts. If 'prefix' is set to "xdg", the value in the XDG_DATA_HOME
environment variable will be added as the path prefix. please see XDG Base Directory Spec‐
ification for more details.
<CACHEDIR PREFIX="DEFAULT">
This element contains a directory name that is supposed to be stored or read the cache of
font information. If multiple elements are specified in the configuration file, the direc‐
tory that can be accessed first in the list will be used to store the cache files. If it
starts with '~', it refers to a directory in the users home directory. If 'prefix' is set
to "xdg", the value in the XDG_CACHE_HOME environment variable will be added as the path
prefix. please see XDG Base Directory Specification for more details. The default direc‐
tory is ``$XDG_CACHE_HOME/fontconfig'' and it contains the cache files named ``<hash
value>-<architecture>.cache-<version'', where <version> is the font configureation file
version number (currently 3).
<INCLUDE IGNORE_MISSING="NO" PREFIX="DEFAULT">
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 incorpo‐
rated 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. If 'prefix' is set to "xdg", the value in
the XDG_CONFIG_HOME environment variable will be added as the path prefix. please see XDG
Base Directory Specification for more details.
<CONFIG>
This element provides a place to consolidate additional configuration information. <con‐
fig> can contain <blank> and <rescan> elements in any order.
<BLANK>
Fonts often include "broken" glyphs which appear in the encoding but are drawn as blanks
on the screen. Within the <blank> element, place each Unicode characters which is supposed
to be blank in an <int> element. Characters outside of this set which are drawn as blank
will be elided from the set of characters supported by the font.
<RESCAN>
The <rescan> element holds an <int> element which indicates the default interval between
automatic checks for font configuration changes. Fontconfig will validate all of the con‐
figuration files and directories and automatically rebuild the internal datastructures
when this interval passes.
<SELECTFONT>
This element is used to black/white list fonts from being listed or matched against. It
holds acceptfont and rejectfont elements.
<ACCEPTFONT>
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 ele‐
ments include glob and pattern elements which are used to match fonts.
<REJECTFONT>
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 sys‐
tem. Rejectfont elements include glob and pattern elements which are used to match fonts.
<GLOB>
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.
<PATTERN>
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.
<PATELT NAME="PROPERTY">
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.
<MATCH TARGET="PATTERN">
This element holds first a (possibly empty) list of <test> elements and then a (possibly
empty) list of <edit> 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 ele‐
ment 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.
<TEST QUAL="ANY" NAME="PROPERTY" TARGET="DEFAULT" COMPARE="EQ">
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", "more_eq",
"contains" or "not_contains". '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.
'ignore-blanks' takes a boolean value. if 'ignore-blanks' is set "true", any blanks in the
string will be ignored on its comparison. this takes effects only when compare="eq" or
compare="not_eq". 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.
<EDIT NAME="PROPERTY" MODE="ASSIGN" BINDING="WEAK">
This element contains a list of expression elements (any of the value or operator ele‐
ments). The expression elements are evaluated at run-time and modify the property "prop‐
erty". The modification depends on whether "property" was matched by one of the associated
<test> 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:
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
"delete" Delete matching value Delete all values
"delete_all" Delete all values Delete all values
<INT>, <DOUBLE>, <STRING>, <BOOL>
These elements hold a single value of the indicated type. <bool> elements hold either true
or false. An important limitation exists in the parsing of floating point numbers -- font‐
config 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).
<MATRIX>
This element holds four numerical expressions of an affine transformation. At their sim‐
plest these will be four <double> elements but they can also be more involved expressions.
<RANGE>
This element holds the two <int> elements of a range representation.
<CHARSET>
This element holds at least one <int> element of an Unicode code point or more.
<LANGSET>
This element holds at least one <string> element of a RFC-3066-style languages or more.
<NAME>
Holds a property name. Evaluates to the first value from the property of the pattern. If
the 'target' attribute is not present, it will default to 'default', in which case the
property is returned from the font pattern during a target="font" match, and to the pat‐
tern during a target="pattern" match. The attribute can also take the values 'font' or
'pattern' to explicitly choose which pattern to use. It is an error to use a target of
'font' in a match that has target="pattern".
<CONST>
Holds the name of a constant; these are always integers and serve as symbolic names for
common font values:

<OR>, <AND>, <PLUS>, <MINUS>, <TIMES>, <DIVIDE>
These elements perform the specified operation on a list of expression elements. <or> and
<and> are boolean, not bitwise.
<EQ>, <NOT_EQ>, <LESS>, <LESS_EQ>, <MORE>, <MORE_EQ>, <CONTAINS>, <NOT_CONTAINS
These elements compare two values, producing a boolean result.
<NOT>
Inverts the boolean sense of its one expression element
<IF>
This element takes three expression elements; if the value of the first is true, it pro‐
duces the value of the second, otherwise it produces the value of the third.
<ALIAS>
Alias elements provide a shorthand notation for the set of common match operations needed
to substitute one font family for another. They contain a <family> element followed by
optional <prefer>, <accept> and <default> elements. Fonts matching the <family> element
are edited to prepend the list of <prefer>ed families before the matching <family>, append
the <accept>able families after the matching <family> and append the <default> families to
the end of the family list.
<FAMILY>
Holds a single font family name
<PREFER>, <ACCEPT>, <DEFAULT>
These hold a list of <family> elements to be used by the <alias> element.

FILES
fonts.conf contains configuration information for the fontconfig library consisting of
directories to look at for font information as well as instructions on editing program
specified font patterns before attempting to match the available fonts. It is in XML for‐
mat.
conf.d is the conventional name for a directory of additional configuration files managed
by external applications or the local administrator. The filenames starting with decimal
digits are sorted in lexicographic order and used as additional configuration files. All
of these files are in XML format. The master fonts.conf file references this directory in
an <include> directive.
fonts.dtd is a DTD that describes the format of the configuration files.
$XDG_CONFIG_HOME/fontconfig/conf.d and ~/.fonts.conf.d is the conventional name for a per-
user directory of (typically auto-generated) configuration files, although the actual
location is specified in the global fonts.conf file. please note that ~/.fonts.conf.d is
deprecated now. it will not be read by default in the future version.
$XDG_CONFIG_HOME/fontconfig/fonts.conf and ~/.fonts.conf is the conventional location for
per-user font configuration, although the actual location is specified in the global
fonts.conf file. please note that ~/.fonts.conf is deprecated now. it will not be read by
default in the future version.
$XDG_CACHE_HOME/fontconfig/*.cache-* and ~/.fontconfig/*.cache-* is the conventional
repository of font information that isn't found in the per-directory caches. This file is
automatically maintained by fontconfig. please note that ~/.fontconfig/*.cache-* is depre‐
cated now. it will not be read by default in the future version.
ENVIRONMENT VARIABLES
FONTCONFIG_FILE is used to override the default configuration file.
FONTCONFIG_PATH is used to override the default configuration directory.
FC_DEBUG is used to output the detailed debugging messages. see Debugging Applications
section for more details.
FONTCONFIG_USE_MMAP is used to control the use of mmap(2) for the cache files if avail‐
able. this take a boolean value. fontconfig will checks if the cache files are stored on
the filesystem that is safe to use mmap(2). explicitly setting this environment variable
will causes skipping this check and enforce to use or not use mmap(2) anyway.
