       showtable - Show data in nicely formatted columns

       showtable [-options] [file]

       Showtable reads an input data stream and displays it in a nicely
       formatted listing, with exact formatting depending upon the options.
       The input stream, file or "STDIN" by default should consist of data
       separated by tabs or the defined separator character (see -d).

       The actual output formatting is peformed by the ShowTable module.

       There are two general sets of options: those which help determine the
       format of the input, and those which determine the format of the

   Options affecting input
		 Set the inter-column break string to "str".  The default is a
		 tab (""\t"").	If -strip is also given, blanks surrounding
		 the break string will also be ignored.

       -dstr	 This is the same as "-break="str.

		 Do not ignore lines of separators, such as dashes, equal
		 signs, or underlines.	If -nodashes is given, and these lines
		 do occur in the stream, they will be treated as normal data.

		 Treat the first NN rows of data as column titles; multiple
		 words in the column titles may wrap vertically. If NN is
		 omitted, it defaults to 1.  No -titles option is the same as

		 Set the input type as type, which can be one of: box, list,
		 table, or simple.  A simple-type table is the same as a
		 table-type, but no wrapping characters are recognized.

       -s(trip)	 Strip blanks from around the column values.

		 Do not strip blanks from the input.  Useful if there is
		 formatted or aligned data within a boxed table.

   Options affecting output
       -t(able)	 Use a table format for output, with wrapping of column values
		 longer than the given or determined column widths.  See
		 ShowTable for more details.

       -si(mple) Use a simple table format, without any wrapping of column
		 values.  See ShowTable for more details.

       -l(ist)	 Use a list style format.  See ShowTable for more details.

       -b(ox)	 Use a "boxed" style table.  See ShowTable for more details.

       -ht(ml)	 Use HTML-formating.  See ShowTable for more details.

		 Define the column names explicitly.  This is useful for
		 naming columns of data from "STDIN", when showtable is being
		 used as a filter.  The first column name, name1, cannot begin
		 with a digit.	This option allows any column titles obtained
		 from the input to be overridden.

		 Do not output any headers on the tables; -titles=0 implies
		 this option.

       -fn1[,n2, ..., nN]
		 Select fields numbered n1, n2, etc., to display.  Each nN is
		 a field index, or a range of indexes in the form: "N"-"M" The
		 default is to show all the fields in each row.	 Fields are
		 numbered from 1.  An example:	to show the first, and three
		 through five fields of the "/etc/passwd" file:

		     showtable -d: -f1,2-5 /etc/passwd

       -fields=fname1[,fname2, ..., fnameN]
		 Select the named fields to display.  The field names must be
		 available, either through the data stream, or by using the
		 -titles option.   The field names given must match the
		 existing field names exactly.

		 Using the file "/etc/passwd" for another example: to show the
		 same first two fields, by name:

		     showtable -d: -titles=Login,UID -fields=Login,UID /etc/passwd

		 Set the maximum table width.  This value is applied to the
		 variable Data::Showtable::Max_Table_Width.  When the total
		 width of all columns to be displayed exceeds this value, all
		 column widths are scaled uniformly.

		 If -width is not given, then for all output but -html, the
		 default value is either ""COLUMNS"", if defined, or 80, if
		 not.  Whith -html mode, there is no default value for -width;
		 in other words, there is no limit to the width.

		 Set individual column widths to the specified values.	Empty
		 column widths imply no maximum width.	If the -width option
		 is also given, then the -cwidth column widths can also be
		 given as fractions or percentages.

		 Example: To set the maximum width of the third column to 20


   HTML-only options (the usage of which implies -html)
		 Do not perform HTML escape sequences on the data; this allows
		 embedded HTML text in the data to be displayed properly with
		 the -html option.

       -attributes='attr1 attr2 ...'
		 Declare the table attributes, which are inserted into the
		 "TABLE" token.	 For example, the option:

		     -attributes='BORDER=0 CELLSPACING=2 CELLPADDING=4'

		 would cause the following HTML:


		 The default table attributes are:


		 Set the HTML formats for the column titles.  The
		 -title_formats (or just -tf) can be given multiple times, for
		 each column, or formats for multiple columns can be given on
		 the same option separated by semi-colons "";"".

		 Each fmtN can itself be multiple HTML items, separated by
		 commas.  Each HTML element can be given either as an HTML
		 token (eg: ""\<BOLD\">"), or as a plain name (eg: ""BOLD"").

		 For example, here is a title format specification for three
		 columns, where the first column title should be bold italic,
		 the second italic, and the third italic in a smaller font:

			 -tf='BOLD,I;I;<FONT SIZE=-2>,I'

		 The same as -title_formats but applies to the column data.

		 Define a mapping from column names, or indexes, to URLs to be
		 inserted as <A HREF's> around the values for the named
		 columns.  Each colN is a column name or index, and each urlN
		 is a string representing the URL to be inserted for the given

		 The URL text may contain these substitution strings:

		 %K - will be substituted with the current column name (or

		 %V - will be substituted with the current column value.

		 Multiple -url options may be given, if desired, rather than
		 creating one long argument for a single -url.	For example:

		     showtable	 -d: -f1,6 -titles=Login,Homedir \
				 -url='Login=mailto:%V' \
				 -url='HomeDir=file:%V' \

   Other options
       -help	 Display some help to the user and quit.

   Boxed Input
       If the input type is box, then vertical and horizontal box characters
       are removed from the input stream, and blanks surrounding the vertical
       box characters are removed.  The vertical box characters (column
       separaters) are ""|"" or "":"".	The The horizontal box characters are
       ""+"" and ""-"".

       Morever, data wrapped within a column is recognized and parsed as one
       column value, by recognizing the presence of a wrapping prefix or
       wrapping suffix character.  Currently, the wrapping prefix character is
       "<", and the wrapping suffix character is ">".

       An example of data wrapped within a column is given here.  The table
       below has just two logical rows of data; with both rows having data
       wrapped into multiple physical rows.

	       |  Col 1	 |  Col 2  |  Col 3  |
	       | This is>| Another>| Row 1,3>|
	       |< a cont>|< value. |<is also>|
	       |<inued	>|	   |<long.   |
	       |<value.	 |	   |	     |
	       |This is >| Item2-2 | Item2-3 |

   List Format
       When using the -list or -input=list options, either, or both, the input
       and output may be in a "list" format, which is implemented using the
       following syntax:

	       r1c1_name: r1c1_value
	       r1c2_name: r1c2_value
	       r1cN_name: r1cN_value

	       r2c1_name: r2c1_value
	       r2c2_name: r2c2_value
			: r2c2_value_continued
	       r2cN_name: r2cN_value

	       rMc1_name: rMc1_value
	       rMc2_name: rMc2_value
	       rMcN_name: rMcN_value

       Each row of data consists of one or more columns, and ends with a blank

       Each column consists of a column name, followed by a colon ":",
       followed by an optional, single space or tab, followed by the column
       value, on the same line.

       Continuation lines of the previous column value consist of one or more
       space or tab characters, a colon ":", one optional, single space or
       tab, followed by the continuation value.	 In the example above, The
       second column value of the second row was continued.

   HTML Input with HTML Output
       When using -html on data already containing HTML-formatted text, the
       -noescape option should be used.	 By default, all input text is assumed
       not to be HTML-formatted, and is escaped allowing embedded "<", ">"
       characters, if any, to be displayed correctly.

       Data::ShowTable module
		 Performs the actual output formatting.

       Alan K. Stebbens

       ·    Currently, the box formatting characters are not configurable: '+'
	    for the corners; '-' and '|' for the tops and sides, respectively.
	    In an ideal world, these things would be configurable.

       ·    The continuation prefix and suffix characters, '<' and '>',
	    respectively, are also not configurable:

       ·    When reading table input, any data ending with ">" will be
	    considered to be continued by the next row of data.	 To avoid
	    this, use -input=simple.

       ·    When selecting noncontiguous fields (ie: -f1,4>) without field
	    names, the default field names will be consecutively numbered from
	    1, which is counter-intuitive to the original selection.  To avoid
	    this, name the fields using the -title=...	option.
