=head1 NAME
fonts-config - configures installed X11 fonts.
=head1 SYNOPSIS
fonts-config [B<OPTION>]...
=head1 OPTIONS
=over 4
=item B<--force-hintstyle> string
By default, "hintstyle" is chosen depending on value of autohint for given font.
Apart from exceptions (e. g. IPA fonts for example): for fonts, with good
instructions*) "hintfull" used and for other fonts "hintslight" is used. You can
enforce hintstyle here. Possible values are "none", "hintnone", "hintslight",
"hintmedium" and "hintfull". This option can be overriden by --force-bw* options,
where "hintfull" is always used.
*) see /usr/share/doc/packages/fonts-config/infinality/good-hinted-tt-fonts.list
for reference
=item B<--force-autohint>
By default, FreeType's autohinter is used for fonts, which have no or not good
native hinting instructions. You can enforce to use autohinter even for
fonts with good instructions*) with this option. hintstyle="hintslight" is used then,
when --force-hintstyle do not everrides it.
*) see /usr/share/doc/packages/fonts-config/infinality/good-hinted-tt-fonts.list
for fonts with good hinting instructions
=item B<--force-bw>
FreeType is instructed to use antialias (font smoothing) in rendering by default.
You can override this settings with this option, which means that fonts will not
bee smoothed but contranst with background will be high, which can suit
one's eyes. Liberation Sans family is then automatically prefered over DejaVu Sans.
Force using bitmap strikes from the font. Hintstlyle is forced to "hintfull"
(this even overrides --force-hintstyle option).
This can produce bitmap quality rendering for good instructed fonts.
=item B<--force-bw-monospace>
This option has lower impact than --force-bw. Sets black and white rendering only
for good hinted monospaced fonts (e. g. Liberation Mono). "hintfull" hintstyle is
used.
=item B<--lcd-filter> string
Defines lcd filter to be used. If not overriden by this option, "lcdnone" is used.
Possible values are "lcdnone", "lcddefault", "lcdlight" and "lcdlegacy".
=item B<--rgba> string
Defines lcd subpixel arrangement and orientation for your monitor. Default value
is "none". Possible values are "none", "rgb", "vrgb", "bgr", "vbgr", "unknown".
=item B<--(no)ebitmaps>
Use (or don't use) embedded bitmaps from font.
=item B<--ebitmapslang> string
Limit use of embedded bitmaps to specified in string separated by colons.
=item B<--sans-families> string
Given colon-separated list of prefered sans families, they will be
prefered over system preference list of sans families*).
*) see /etc/fonts/conf.d/60-family-prefer.conf for details
=item B<--mono-families> string
Given colon-separated list of prefered monospace families, they will be
prefered over system preference list of monospace families*).
*) see /etc/fonts/conf.d/60-family-prefer.conf for details
=item B<--serif-families> string
Given colon-separated list of prefered serif families, they will be
prefered over system preference list of serif families*).
*) see /etc/fonts/conf.d/60-family-prefer.conf for details
=item B<--(no)forcefpl>
Value of B<--*-families> can be overriden, when document or GUI is
requesting some particular font. This is very often intended.
With B<--forcefpl>, it is possible to override all such requests with
fonts listed in family preference lists (FPLs).
=item B<--(no)ttcap>
Generate (or don't generate) TTCap entries. TTCap entries can be used
with the xtt module and with recent versions of the freetype module.
=item B<--(no)java>
Generate (or don't generate) font setup for Java.
=item B<-u>, B<--user>
run fontconfig setup for user. it reads ~/.config/fontconfig/fonts-config,
which is user analogy of /etc/sysconfig/fonts-config.
=item B<-U>, B<--remove-user-setting>
remove user setting created by by B<--user>.
=item B<-f>, B<--force>
Force the update of all generated files even if it appears to be
unnecessary according to the time stamps.
=item B<-q>, B<--quiet>
Work silently, unless an error occurs.
=item B<-v>, B<--verbose>
Print some progress messages to standard output.
=item B<-d>, B<--debug>
Print a lot of debugging messages to standard output.
=item B<--version>
Display version and exit.
=item B<-h>, B<--help>
Display a short help message and exit.
=item B<-i>, B<--info>
Lists important involved input and output files to fonts-config script.
=back
=head1 DESCRIPTION
Configures installed X11 fonts. Basically it does the following
things:
=over 4
=item B<creates fonts.scale and fonts.dir files>
fonts-config currently assumes all fonts installed in /usr/share/fonts
tree.
For each subdirectory, the time stamps of the directory, the
B<fonts.scale> file, the B<fonts.dir> file and an extra time stamp
file B<.fonts-config-timestamp> are checked. If not all the time
stamps are equal or any of these files is missing, the B<fonts.scale>
and B<fonts.dir> files will be updated as follows:
First, B<fonts.scale> file is created by calling B<mkfontscale>.
Then, the entries found in the B<fonts.scale> file are merged with
the entries from all B<fonts.scale.*> files.
B<fonts.scale.*> files may be supplied by rpm-packages or manually
added by the user to override or amend the entries created
automatically by B<mkfontscale>. Entries in a B<fonts.scale.*> file
have higher priority than entries automatically created by
B<mkfontscale>. All entries generated automatically by B<mkfontscale>
for a certain font file are discarded if any B<fonts.scale.*> file
contains an entry for the same font file.
After the final list of entries has been written back to
B<fonts.scale>, B<mkfontdir> is called.
Finally, the time stamps of the directory, B<fonts.scale>,
B<fonts.dir>, and B<.fonts-config-timestamp> are set to the time when
B<fonts-config> started.
=item B<generate rendering options>
Generates /etc/fonts/conf.d/10-rendering-options.conf according to
rendering options or its bound sysconfig variables. See
--force-hintstyle, --force-autohint, --force-bw, --force-bw-monospace,
--lcdfilter, --rgba, --ebitmaps, --ebitmapslang options.
=item B<call fc-cache>
creates cache files for fonts to use with client side font rendering
via fontconfig/libXft, for details see L<fc-cache(1)>.
B<fonts.cache-2> cache files are generated in B</var/cache/fontconfig>
for all directories which are configured in B</etc/fonts/fonts.conf>
and all their subdirectories.
=back
Usually B<fonts-config> is called automatically when package containing
font is installed, upgraded or removed. But you can also execute
B<fonts-config> directly, which is mainly useful to debug it (use
--debug flag).
=head1 FILES
=over 4
=item B</etc/sysconfig/fonts-config>
Default values for some command line options of fonts-config are read
from this file if it exists. The options currently supported in
this file are:
=item FORCE_HINSTYLE
can be set to "none", "hintfull", "hintmedium" , "hintslight" or "hintnone" and
is bound to B<--force-hintstyle> option.
=item FORCE_AUTOHINT
