.SH NAME
mkfontdir \- create an index of X font files in a directory
.SH SYNOPSIS
.B "mkfontdir"
.RB [ \-n ]
.RB [ \-x
.IR suffix ]
.RB [ \-r ]
.RB [ \-p
.IR prefix ]
.RB [ \-e
.IR encoding-directory-name ]
\|.\|.\|.
.RB [ \-\- ]
.RI [ directory-name
\|.\|.\|. ]
.SH DESCRIPTION
For each directory argument,
.I mkfontdir
reads all of the font files in the
directory searching for properties named "FONT", or (failing that) the name
of the file stripped of its suffix.  These are converted to lower case and
used as font names, and,
along with the name of the font file, are
written out to the file "fonts.dir" in the directory.
The X server and font server use "fonts.dir" to find font files.
.PP
The kinds of font files read by
.I mkfontdir
depend on configuration
parameters, but typically include PCF (suffix ".pcf"), SNF (suffix ".snf")
and BDF (suffix ".bdf").  If a font exists in multiple formats,
.I mkfontdir
will first choose PCF, then SNF and finally BDF.
.PP
The first line of fonts.dir gives the number of fonts in the file.
The remaining lines list the fonts themselves, one per line, in two
fields.  First is the name of the font file, followed by a space and
the name of the font.
.SH "SCALABLE FONTS"
Because scalable font files do not usually include the X font name, the
file "fonts.scale" can be used to name the scalable fonts in the
directory.
The fonts listed in it are copied to fonts.dir by
.IR mkfontdir .
"fonts.scale" has the same format as the "fonts.dir" file, and can be
created with the
.IR mkfontscale (__appmansuffix__)
program.
.SH "FONT NAME ALIASES"
The file "fonts.alias", which can be put in any directory of the font-path, is
used to map new names to existing fonts, and should be edited by hand.  The
format is two white-space separated columns, the
first containing aliases and the second containing font-name patterns.
Lines beginning with "!" are comment lines and are ignored.
.PP
If neither the alias nor the value specifies the size fields of the
font name, this is a scalable alias.  A font name of any size that
matches this alias will be mapped to the same size of the font that
the alias resolves to.
.PP
When a font alias is used, the name it references is searched for in the normal
manner, looking through each font directory in turn.  This means that the
aliases need not mention fonts in the same directory as the alias file.
.PP
To embed white space in either name, simply enclose it in double-quote
marks; to embed double-quote marks (or any other character), precede them
with back-slash:
.PP
.nf
"magic-alias with spaces"	"\\"font name\\" with quotes"
regular-alias			fixed
.fi
.PP
If the string "FILE_NAMES_ALIASES" stands alone on a line, each file-name
in the directory (stripped of its suffix) will be used as an alias for
that font.
.SH ENCODING FILES
The option
.B -e
can be used to specify a directory with encoding files.  Every such
directory is scanned for encoding files, the list of which is then
written to an "encodings.dir" file in every font directory.  The
"encodings.dir" file is used by the server to find encoding
information.
.PP
The "encodings.dir" file has the same format as "fonts.dir".
It maps encoding names (strings of the form
.BI CHARSET_REGISTRY \- CHARSET_ENCODING
) to encoding file names.
.SH OPTIONS
The following options are supported:
.TP
.B \-e
Specify a directory containing encoding files.  The
.B \-e
option may be specified multiple times, and all the specified
directories will be read.  The order of the entries is significant, as
encodings found in earlier directories override those in later ones;
encoding files in the same directory are discriminated by preferring
compressed versions.
.TP
.B \-n
do not scan for fonts, do not write font directory files.  This option
is useful when generating encoding directories only.
.TP
.B \-p
Specify a prefix that is prepended to the encoding file path names
when they are written to the "encodings.dir" file.  The prefix is
prepended as-is.  If a `/' is required between the prefix and the path
names, it must be supplied explicitly as part of the prefix.
.TP
.B \-r
Keep non-absolute encoding directories in their relative form when
writing the "encodings.dir" file.  The default is to convert relative
encoding directories to absolute directories by prepending the current
directory.  The positioning of this options is significant, as this
option only applies to subsequent
.B \-e
options.
.TP
.BI "\-x " suffix
Ignore fonts files of type
.IR suffix .
.TP
.B \-\-
End options.
.SH FILES
.TP 15
.B fonts.dir
List of fonts in the directory and the files they are stored in.
Created by \fImkfontdir\fP.  Read by the X server and font server each
time the font path is set (see xset(__appmansuffix__)).
.TP 15
.B fonts.scale
List of scalable fonts in the directory.  Contents are copied to
fonts.dir by \fImkfontdir\fP.   Can be created with
.IR mkfontscale (__appmansuffix__).
.TP 15
.B fonts.alias
List of font name aliases.
Read by the X server and font server each
time the font path is set (see xset(__appmansuffix__)).
.TP 15
.B encodings.dir
List of known encodings and the files they are stored in.
Created by \fImkfontdir\fP.  Read by the X server and font server each
time a font with an unknown charset is opened.
