=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)metric>

Value of B<--*-families> can be overriden when document 
or GUI is requesting metric compatible font as defined
    in /etc/fonts/conf.d/30-metric-aliases.conf,
e. g. request to Times New Roman will get Liberation Serif
even if other family is explicitely prefered by B<--serif-families>
option. (hint, that's because binding="same" in that fontconfig)

You can change this default behaviour with B<--nometric>, but be careful
with that. Metric compatibility means that every glyph, say 'A', has 
the same width and height in both fonts, so document should have same 
line wraps for example.

=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.

=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).
