.SH NAME
boxes \- text mode box and comment drawing filter
.SH SYNOPSIS
.B boxes
[-hlrv] [\-a\ format] [\-d\ design] [\-f\ file] [\-i\ indent] [\-k\ bool]
[\-p\ pad] [\-s\ size] [\-t\ tabs] [infile [outfile]]
.SH DESCRIPTION
.I boxes
is a text filter which can draw any kind of ASCII art box around its input
text. A box can also be removed, even if it has been badly damaged by
editing of the text inside. Since boxes may be open on any side,
.I boxes
can also be used to create regional comments in any programming language.
With the help of an editor macro/mapping, damaged boxes can easily be
repaired. New box designs of all sorts can easily be added and shared by
appending to a free format configuration file.
.br
.I boxes
was intended to be used with the
.I vim(1)
text editor, but can be tied to any text editor which supports filters, as
well as from the command line as a standalone tool.

.SH OPTIONS
Options offered by
.I boxes
are the following:
.TP 0.6i
.B -a \fIstring\fP
Alignment/positioning of text inside box. This option takes a format string
argument which is read from left to right. The format string may not
contain whitespace and must consist of one or more of the following
components:
.br

.B h\fPx
- horizontal alignment of the input text block inside a potentially larger
box. Possible values for
.I x
are
.B l
(ell, for left alignment),
.B c
(center), or
.B r
(right). This does not affect the justification of text lines within the
input text block (use the
.B j
argument instead).
.br
.B v\fPx
- vertical alignment of the input text block inside a potentially larger
box. Possible values for
.I x
are
.B t
(for top alignment),
.B c
(center), or
.B b
(bottom).
.br
.B j\fPx
- justification of lines within the input text block. Possible values for
.I x
are
.B l
(ell, for left justification),
.B c
(center), or
.B r
(right). This does not affect the alignment of the input text block itself
within the box. Use the
.B h
and
.B v
arguments for input text block positioning.
.br

Short hand notations (can be combined with the above arguments):
.br
.B l
- (ell) short for
.B h\fPl\fBv\fPc\fBj\fPl
.br
.B c
- short for
.B h\fPc\fBv\fPc\fBj\fPc
.br
.B r
- short for
.B h\fPr\fBv\fPc\fBj\fPr
.br

The factory default setting for
.B -a
is
.B h\fPl\fBv\fPt.

use.

valid
.I boxes
config file, containing new and exciting designs!

.B -i \fIstring\fP
Indentation mode. Possible arguments are "text" (indent text inside of
box), "box" (indent box, not text inside of box), or "none" (throw away
indentation). Arguments may be abbreviated. The default is to indent the
box, but not the text.

.TP 0.6i
.B -k \fIbool\fP
Kill leading/trailing blank lines on removal. The value of
.I bool
can be specified as on, yes, true, 1, or t, all meaning yes, or off, no,
false, 0, or f, which mean no. This is case-insensitive. This option only
takes effect in connection with
.B -r\fP.
If set to yes, leading and trailing blank lines will be removed from the
output. If set to no, the entire content of the former box is returned.
The default is no, if both the top and the bottom part of the box are open,
as is the case with most regional comments. If the box's design defines a
top part or a bottom part, the default is yes.

.B -l
(ell) List designs. Produces a listing of all available box designs in the
config file, along with a sample box and information about it's creator.
Also checks syntax of the entire config file. If used in connection with
.B -d\fP,
displays detailed information about the specified design.

.TP 0.6i
.B -p \fIstring\fP
Padding. Specify padding in spaces around the input text block for all
sides of the box. The argument string may not contain whitespace and must
consist of a combination of the following characters, each followed by a
number indicating the padding in spaces:
.br
.B a
- (all) give padding for all sides at once
.br
.B h
- (horiz) give padding for both horizontal sides
.br
.B v
- (vertical) give padding for both vertical sides
.br
.B b
- (bottom) give padding for bottom (south) side
.br
.B l
- (left) give padding for left (west) side
.br
.B t
- (top) give padding for top (north) side
.br
.B r
- (right) give padding for right (east) side
.br
Example:
.B -p a\fP4\fBt\fP2
would define the padding to be 4 characters on all sides, except for the
top of the box, where the input text block will be only 2 lines away from
the box.
.br
By default, unless specified otherwise in the config file, no padding is
used.

.B -r
Remove box. Removes an existing box instead of drawing it. Which design to
use is detected automatically. In order to save time or in case the
detection does not decide correctly, combine with
.B -d
to specify the design. The default is to draw a new box.

.TP 0.6i
.B -s \fIwidth\fBx\fPheight\fP
Box size. If a single number is given as argument, this defaults to the box
width. 'x', followed by a single number specifies the box height. Giving
both the box width and height is left as an exercise to the reader. :-)
The actual box size may vary depending on the individual shape sizes.
By default, the smallest possible box is created around the text.

.TP 0.6i
.B -t \fIuint\fP
Distance between tab stops. It is important that this value is set correctly,
or tabulator characters will upset your input text. The correct value for
.B -t
depends on the settings used for the text you are processing. Usually, a
value of 8 should be okay. The factory default for
.B -t
is 8.

.\" =======================================================================
.SH CONFIGURATION FILES
.I Boxes
will use the configuration file specified on the command line (using
.B -f\fP).
If no config file is specified on the command line,
.I boxes
will check for the BOXES environment variable, which may contain a filename
to use. If BOXES is not set,
.I boxes
will try to read $HOME/.boxes and use it as a config file. Failing that,
.I boxes
will try to read the system-wide config file (see FILES).
.PP
The syntax of
.I boxes
config files is described on the Web page (see below). They are quite
self-explanatory, though.

Although it is doing great in most cases, imho the design autodetector
needs some more work.
