boxes - text mode box and comment drawing filter SYNOPSIS
boxes [-hlrv] [-a format] [-d design] [-f file] [-i indent] [-k bool] [-p pad] [-s size] [-t tabs] [infile [outfile]] DESCRIPTION
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, boxes can also be used to create regional comments in any pro- gramming 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. boxes was intended to be used with the 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. 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 align- ment), 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. -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. -p string Padding. Specify padding in spaces around the input text block for all sides of the box. The argument string may not contain white- space 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. 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. -t uint 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 -t depends on the settings used for the text you are processing. Usually, a value of 8 should be okay. The factory default for -t is 8. -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 Web page (see below). They are quite self-explanatory, though. AVAILABILITY
boxes is available from its World Wide Web home page at The Web page also features a number of exam- ples illustrating this manual page as well as more in-depth documentation. Check out the vim(1) home page at! AUTHOR
