NAME


boxes - text mode box and comment drawing filter

SYNOPSIS


boxes [-hlmrv] [-a format] [-d design] [-f file] [-i indent] [-k bool] [-p pad] [-s size]
[-t tabopts] [infile [outfile]]

DESCRIPTION


Boxes is a text filter which can draw any kind of box around its input text. Box design
choices range from simple boxes to complex ASCII art. A box can also be removed and
repaired, even if it has been badly damaged by editing of the text inside. Since boxes may
be open on any side, boxes can also be used to create regional comments in any programming
language. New box designs of all sorts can easily be added and shared by appending to a
free format configuration file.
boxes was originally intended to be used with the vim(1) text editor, but it can be tied
to any text editor which supports filters, as well as called from the command line as a
standalone tool.

OPTIONS


Options offered by boxes are the following:

-a string
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:

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

Short hand notations (can be combined with the above arguments):
l (ell) - short for hlvcjl
c - short for hcvcjc
r - short for hrvcjr

The factory default setting for -a is hlvt.

-c string
Command line design definition for simple cases. The argument of this option is the
definition for the "west" (W) shape. The defined shape must consist of exactly one
line, i.e. no multi-line shapes are allowed. The -c option is intended as a shortcut
for those cases where simple regional comments are to be created, which only need a
certain character or sequence of characters to be placed in front of every line. In
such cases, it is much more convenient to simply specify -c than to do a complete
design definition in one's config file, where the only shape defined is the west
shape.
This option implies a -d and does not access the config file. -c may of course be
used in conjunction with any of the other options. By default, -c is not specified.

-d string
Design selection. The one argument of this option is the name of the design to use.

-f string
Use alternate config file. The one argument of this option is the name of a valid
boxes config file, containing new and exciting designs!

-h Print usage information.

-i string
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.

-k bool
Kill leading/trailing blank lines on removal. The value of 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 -r. 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.

-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 -d, displays detailed
information about the specified design.

-m Mend box. This removes a (potentially broken) box as with -r, and redraws it
afterwards. The mended box is drawn according to the options given. This may be
important to know when it comes to restoring padding, identation, etc. for the
mended box. Implies -k false.

-p string
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:
a - (all) give padding for all sides at once
h - (horiz) give padding for both horizontal sides
v - (vertical) give padding for both vertical sides
b - (bottom) give padding for bottom (south) side
l - (left) give padding for left (west) side
t - (top) give padding for top (north) side
r - (right) give padding for right (east) side
Example: -p a4t2 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.
By default, unless specified otherwise in the config file, no padding is used.

-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 -d to specify the design. The default is to draw a
new box.

-s widthxheight
Box size. This option specifies the desired box size in units of columns (for width)
and lines (for height). If only a single number is given as argument, this number
specifies the desired box width. A single number prefixed by 'x' specifies only the
box height. The actual resulting box size may vary depending on the individual
shape sizes of the chosen design. Also, other command line options may influence the
box size (such as -p).
By default, the smallest possible box is created around the text.

-t string
Tab handling. This option controls how tab characters in the input text are handled.
The option string must always begin with a uint number indicating the distance
between tab stops. It is important that this value be set correctly, or tabulator
characters will upset your input text. The correct tab distance value depends on
the settings used for the text you are processing. A common value is 8.
Immediately following the tab distance, an optional character can be appended,
telling boxes how to treat the leading tabs. The following options are available:
e - expand tabs into spaces
k - keep tabs as close to what they were as possible
u - unexpand tabs. This makes boxes turn as many spaces as possible into tabs.

In order to maintain backwards compatibility, the -t string can be just a number. In
that case, e is assumed for tab handling, which removes all tabs and replaces them
with spaces. The factory default for the -t option is simply 8, which is just such a
case.
For example, you could specify -t 4u in order to have your leading tabs unexpanded.
In the box content, tabs are always converted into spaces. The tab distance in this
example is 4.

-v Print out current version number.

CONFIGURATION FILES


Boxes will use the configuration file specified on the command line (using -f). If no
config file is specified on the command line, boxes will check for the BOXES environment
variable, which may contain a filename to use. If BOXES is not set, boxes will try to read
$HOME/.boxes and use it as a config file. Failing that, boxes will try to read the
system-wide config file (see FILES).

The syntax of boxes config files is described on the website (see below). They are quite
self-explanatory, though.

AVAILABILITY

also features a number of examples illustrating this manual page as well as more in-depth
documentation.
