.SH NAME
.B buildtables
\- build
.B troff
tables on a PostScript printer
.SH SYNOPSIS
\*(mBbuildtables\f1
.OP "" options []
.OP "" "name \(el" []
.SH DESCRIPTION
.B buildtables
builds font width tables or the typesetter description
file on a PostScript printer.
No arguments means build a default set of tables;
usually a superset of the LaserWriter Plus collection.
The following
.I options
are understood:
.TP 1.0i
.OP \-b speed
Transmit data over
.I line
at baud rate
.I speed.
Recognized baud rates are 1200, 2400, 4800, 9600, and 19200.
The default
.I speed
is 9600 baud.
.TP 1.0i
.OP \-l line
Build the tables on the PostScript printer attached to
.I line.
There is no default.
.TP 1.0i
.OP \-t name
Use
.I name
as the template for fonts not in the default set.
Choose
.MW R
for proportionally spaced fonts and
.MW CW
for fixed width fonts.
Try
.MW ZD
(ZapfDingbats) if the font has a non-standard
character set.
The default is
.MR R .
.TP 1.0i
.OP \-C file
Copy
.I file
into each PostScript table program;
.I file
must contain legitimate PostScript.
.TP 1.0i
.OP \-H hostdir
Use
.I hostdir
as the host-resident font directory.
A file in
.I hostdir
that matches the name of the
.B troff
font is assumed to be a host-resident font program and is included
in the PostScript width table program.
There is no default.
.TP 1.0i
.OP \-S file
Use
.I file
as the shell library file.
Overrides the choice made with the
.OP \-T
option.
.TP 1.0i
.OP \-T name
Set the target device to
.I name.
.br
Device
.I name
means
.ft 2
.MI \*(dF/dev name /shell.lib
.ft 1
is the shell library file.
There is no default.
.PP
If
.OP \-l
is omitted output files are the PostScript programs that
build the tables, rather than the tables themselves.
One of
.OP \-T
or
.OP \-S
is required.
If both are given
.OP \-S
wins.
Although
.OP \-H
is the preferred mechanism for including host-resident font files,
.OP \-C
makes sense when only one width table is built.
.PP
The shell library file defines a collection of functions used to
build
.BR troff (1)
tables.
The default set of tables is the list of names returned by the
.MW AllTables
function.
Changes to the default list can be made by updating the
.MW BuiltinTables
function.
.PP
Each
.B buildtables
argument
must be a default table name, or a pair of names enclosed in quotes.
If the argument is a pair, the first name is the
.B troff
font and the second is the full PostScript font name.
Tables are created in the current directory.
Each is assigned a name that matches the
.B troff
table name.
.PP
The PostScript table programs created by
.BR trofftable (1)
are written to files that have
.MW .ps
appended to the
.B troff
table name.
The
.MW .ps
file is deleted after the table is built.
Options not listed above are passed to
.B trofftable.
The PostScript table programs return data to the host computer using
PostScript's
.MW print
operator.
See
.BR hardcopy (1)
if you do not have access to the printer's serial port.
.SH EXAMPLES
.PP
Build the default collection of devpost tables on the printer
connected to
.MW /dev/tty00
(no font name arguments):
.EX
buildtables -l/dev/tty00 -Tpost
.EE
To do the same and to restrict the tables that are built,
Add
.B troff
font names (or
.MR DESC )
to restrict the tables built on the printer connected to
.MR /dev/tty00 :
.EX
buildtables -l/dev/tty00 -Tpost R I B BI DESC S
.EE
Enclose the
.B troff
and PostScript font names in quotes to
build the width table for a font not in the default set
(also on the printer connected to
.MR /dev/tty00 ):
.EX
buildtables -l/dev/tty00 -TLatin1 "GL Garamond-Light"
.EE
A font must be available on the printer when the table is built.
Use
.OP \-H
or
.OP \-C
to include host-resident fonts.
.SH WARNINGS
.PP
A width table will not build properly if the printer cannot access
the PostScript font.
.PP
The
.OP \-TLatin1
option only works on PostScript printers that support the full
.SM ISO
Latin-1 character set.
The error message from older printers will likely indicate a missing
.MW ISOLatin1Encoding
array.
