DESCRIPTION
The ShowTable module provides subroutines to display tabular data, typially from a
database, in nicely formatted columns, in several formats. Its arguments can either be
given in a fixed order, or, as a single, anonymous hash-array.
The output format for any one invocation can be one of four possible styles:
Box A tabular format, with the column titles and the entire table surrounded by a
"box" of ""+"", ""-"", and ""|"" characters. See "ShowBoxTable" for details.
Table A simple tabular format, with columns automatically aligned, with column titles.
See "ShowSimpleTable".
List A list style, where columns of data are listed as a name:value pair, one pair
per line, with rows being one or more column values, separated by an empty line.
See "ShowListTable".
HTML The data is output as an HTML TABLE, suitable for display through a Web-client.
See "ShowHTMLTable". Input can either be plain ASCII text, or text with
embedded HTML elements, depending upon an argument or global parameter.
The subroutines which perform these displays are listed below.
EXPORTED NAMES
This module exports the following subroutines:
ShowDatabases - show list of databases
ShowTables - show list of tables
ShowColumns - show table of column info
ShowTable - show a table of data
ShowRow - show a row from one or more columns
ShowTableValue - show a single column's value
ShowBoxTable - show a table of data in a box
ShowListTable - show a table of data in a list
ShowSimpleTable - show a table of data in a simple table
ShowHTMLTable - show a table of data using HTML
PlainText - convert HTML text into plain text
All of these subroutines, and others, are described in detail in the following sections.
MODULES
ShowTable
Format and display the contents of one or more rows of data.
ShowTable { parameter => value, ... };
ShowTable \@titles, \@types, \@widths, \&row_sub [, \&fmt_sub [, $max_width ] [,
$show_mode ] ];
The ShowTable subroutine displays tabular data aligned in columns, with headers.
ShowTable supports four modes of display: Box, Table, List, and HTML. Each mode is
described separately below.
The arguments to ShowTable may be given in one of two ways: as a hashed-array, or by a
combination of fixed order arguments, and some package-global variable settings. The
hash-array parameters correspond to the fixed arguments and the global-parameter settings.
In the list below, both the hash-array parameter name and the fixed-order argument name is
given as the value. In the case where there is no fixed-order argument for a given
parameter-value pair, then the corresponding global variable name is given.
"titles" => \@titles
A reference to an array of column names, or titles. If a particular column name
is null, then the string "Field_num" is used by default. To have a column have
no title, use the empty string.
"types" => \@types
A reference to an array of types, one for each column. These types are passed
to the fmt_sub for appropriate formatting. Also, if a column type matches the
regexp ""/text|char|string/i"", then the column alignment will be left-
justified, otherwise it will be right-justified.
"widths" => \@widths
A reference to an array of column widths, which may be given as an integer, or
as a string of the form: "width.precision".
"row_sub" => \&row_sub
A reference to a subroutine which successively returns rows of values in an
array. It is called for two purposes, each described separately:
* To fetch successive rows of data:
@row = &$row_sub(0);
When given a null, zero, or empty argument, the next row is returned.
* To initialize or rewind the data traversal.
$rewindable = &$row_sub(1);
When invoked with a non-null argument, the subroutine should rewind its row
pointer to start at the first row of data. If the data which row_sub is
traversing is not rewindable, it must return zero or null. If the data is
rewindable, a non-null, non-zero value should be returned.
The row_sub must expect to be invoked once with a non-null argument, in order to
discover whether or not the data is rewindable. If the data cannot be rewound,
row_sub will thereafter only be called with a zero argument.
Specifically, row_sub subroutine is used in this manner:
$rewindable = &$row_sub(1);
if ($rewindable) {
while ((@row = &$row_sub(0)), $#row >= 0) {
# examine lengths for optimal formatting
}
&$row_sub(1); # rewind
}
while ((@row = &$row_sub(0)), $#row >= 0) {
# format the data
}
The consequence of data that is not rewindable, a reasonably nice table will
still be formatted, but it may contain fairly large amounts of whitespace for
wide columns.
"fmtsub" => \&fmt_sub
A reference to a subroutine which formats a value, according to its type, width,
precision, and the current column width. It is invoked either with a fixed list
of arguments, or with a hash-array of parameter and value pairs.
$string = &fmt_sub { I<parameter> => I<value>, ... };
$string = &fmt_sub($value, $type, $max_width, $width, $precision)
If \&fmt_sub is omitted, then a default subroutine, ShowTableValue, will be
used, which will use Perl's standard string formatting rules.
The arguments to \&fmt_sub, either as values passed in a fixed order, or as part
of the parameter value pair, are described in the section on "ShowTableValue
below.
"max_width" => number,
The maximum table width, including the table formatting characters. If not
given, defaults to the global variable $Max_Table_Width;
"show_mode" => 'mode',
The display mode of the output. One of five strings: 'Box', 'Table', 'Simple',
'List', and 'HTML'.
ShowDatabases
Show a list of database names.
ShowDatabases \@dbnames;
ShowDatabases { 'data' => \@dbnames, parameter => value, ...};
ShowDatabases is intended to be used to display a list of database names, under the column
heading of "Databases". It is a special case usage of ShowTable (and can thus be passed
any parameter suitable for ShowTable.
The argument, \@dbnames, is a reference to an array of strings, used as the values of the
single column display.
ShowTables
Show an array of table names.
ShowTables \@tblnames;
ShowTables { 'data' => \@tblnames, parameter => value, ...};
ShowTables is used to display a list of table names, under the column heading of "Tables".
It is a special case usage of ShowTable, and can be passed any "ShowTable" argument
parameter.
ShowColumns
Display a table of column names, types, and attributes.
ShowColumns { parameter => values, ... };
ShowColumns \@columns, \@col_types, \@col_lengths, \@col_attrs;
The ShowColumns subroutine displays a table of column names, types, lengths, and other
attributes in a nicely formatted table. It is a special case usage of ShowTable, and can
be passed any argument suitable for "ShowTable";
The arguments are:
"columns" = \@columns
An array of column names. This provides the value for the first column of the
output.
"col_types" = \@col_types
An array of column types names. This provides the value for the second column.
"col_lengths" = \@col_lengths
An array of maximum lengths for corresponding columns. This provides the value
for the third column of the output.
"col_attrs" = \@col_attrs
An array of column attributes array references (ie: an array of arrays). The
attributes array for the first column are at "$col_attrs-\>[0]". The first
attribute of the second column is "$col_attrs-\>[1][0]".
The columns, types, lengths, and attributes are displayed in a table with the column
headings: "Column", "Type", "Length", and "Attributes". This is a special case usage of
ShowTable, and can be passed additional arguments suitable for "ShowTable".
ShowBoxTable
Show tabular data in a box.
ShowBoxTable { parameter = value, ... };
ShowBoxTable \@titles, \@types, \@widths, \&row_sub [, [ \&fmt_sub ] [, $max_width ] ];
The ShowBoxTable displays tabular data in titled columns using a "box" of ASCII graphics,
looking something like this:
+------------+----------+-----+----------+
| Column1 | Column2 | ... | ColumnN |
+------------+----------+-----+----------+
| Value11 | Value12 | ... | Value 1M |
| Value21 | Value22 | ... | Value 2M |
| Value31 | Value32 | ... | Value 3M |
| ... | ... | ... | ... |
| ValueN1 | ValueN2 | ... | Value NM |
+------------+----------+-----+----------+
The arguments are the same as with "ShowTable". If the @titles array is empty, the header
row is omitted.
ShowSimpleTable
Display a table of data using a simple table format.
ShowSimpleTable \@titles, \@types, \@widths, \&row_sub [, \&fmt_sub];
ShowSimpleTable { parameter => values, ... };
The ShowSimpleTable subroutine formats data into a simple table of aligned columns, in the
following example:
Column1 Column2 Column3
------- ------- -------
Value1 Value2 Value3
Value12 Value22 Value32
Columns are auto-sized by the data's widths, plus two spaces between columns. Values
which are too long for the maximum colulmn width are wrapped within the column.
ShowHTMLTable
Display a table of data nicely using HTML tables.
ShowHTMLTable { parameter => value, ... };
ShowHTMLTable \@titles, \@types, \@widths, \&row_sub [, \&fmt_sub [, $max_width [,
\%URL_Keys [, $no_escape [, \@title_formats [, \@data_formats [, $table_attrs ] ] ] ] ] ]
];
The ShowHTMLTable displays one or more rows of columns of data using the HTML "\<TABLE\">
feature. In addition to the usual parameter arguments of "ShowTable", the following
parameter arguments are defined:
"url_keys" => \%URL_Keys,
This is a hash array of column names (titles) and corresponding base URLs. The
values of any column names or indexes occuring as keys in the hash array will be
generated as hypertext anchors using the associated printf-like string as the
base URL. Either the column name or the column index (beginning with 1) may be
used as the hash key.
In the string value, these macros can be substituted:
"%K" is replaced with the column name.
"%V" is replaced with the column value;
"%I" is replaced with the column index.
For example, if we define the array:
$base_url = "http://www.$domain/cgi/lookup?col=%K?val=%V";
%url_cols = ('Author' => $base_url,
'Name' => $base_url);
Then, the values in the "Author" column will be generated with the following
HTML text:
<A HREF="http://www.$domain/cgi/lookup?col=Author?val=somevalue>somevalue</A>
and the values in the "Name" column will be generated with the URL:
<A HREF="http://www.$domain/cgi/lookup?col=Name?val=othervalue>othervalue</A>
If this variable is not given, it will default to the global variable
"\%URL_Keys".
"no_escape" => boolean,
Unless $no_escape is set, HTML-escaping is performed on the data values in order
to properly display the special HTML formatting characters : '\<', '\>', and
'&'. If you wish to display data with embedded HTML text, you must set
$no_escape.
Enabling embedded HTML, turns on certain heuristics which enable the user to
more completely define appearance of the table. For instance, any "\<TR\">
tokens found embedded *anywhere* within a row of data will be placed at the
front of the row, within the generated "\<TR\">.
Similarly, a row of data containing the "\<THEAD\"> or "\<TFOOT\"> tokens, and
their closing counterparts, will begin and end, respectively a table header or
footer data.
"title_formats" => \@title_formats,
"tformats" => \@title_formats,
An array of HTML formatting elements for the column titles, one for each column.
Each array element is a list of one or more HTML elements, given as
"\<ELEMENT\"> or plainly, "ELEMENT", and separated by a comma ',', semi-colon
';', or vertical bar '|'. Each given HTML element is prepended to the
corresponding column title, in the order given. The corresponding HTML closing
elements are appended in the opposite order.
For example, if \@title_formats contains the two elements:
[ 'FONT SIZE=+2,BOLD', 'FONT COLOR=red,EM' ]
then the text output for the title of the first column would be:
<FONT SIZE=+2><BOLD>I<column_1_title></BOLD></FONT>
If "title_formats" is omitted, the global variable @Title_Formats is used by
default.
"data_formats" => \@data_formats,
"dformats" => \@data_formats,
Similar to "title_formats", this array provides HTML formatting for the columns
of each row of data. If "data_formats" is omitted or null, then the global
variable \@Data_Formats is used by default.
"table_attrs" => $table_attrs,
This variable defines a string of attributes to be inserted within the
"\<TABLE\"> token. For example, if the user wishes to have no table border:
ShowHTMLTable {
...
table_attrs => 'BORDER=0',
...
};
ShowListTable
Display a table of data using a list format.
ShowListTable { parameter => value, ... };
ShowListTable \@titles, \@types, \@widths, \&row_sub [, \&fmt_sub [, $max_width [,
$wrap_margin ] ] ];
The arguments for ShowListTable are the same as for "ShowTable", except for those
described next.
"max_width" = number,
"wrap_margin" = number,
Lines are truncated, and wrapped when their length exceeds $max_width. Wrapping
is done on a word-basis, unless the resulting right margin exceeds $wrap_margin,
in which case the line is simply truncated at the $max_width limit.
The $max_width variable defaults to $Max_List_Width. The $wrap_margin defaults
to $List_Wrap_Margin.
In List mode, columns (called "fields" in List mode) are displayed wth a field name and
value pair per line, with records being one or more fields . In other words, the output
of a table would look something like this:
Field1_1: Value1_1
Field1_2: Value1_2
Field1_3: Value1_3
...
Field1-N: Value1_M
<empty line>
Field2_1: Value2_1
Field2_2: Value2_2
Field2_3: Value2_3
...
Field2_N: Value2_N
...
FieldM_1: ValueM_1
FieldM_2: ValueM_2
...
FieldM_N: ValueM_N
<empty line>
<empty line>
Characteristics of List mode:
o two empty lines indicate the end of data.
o An empty field (column) may be omitted, or may have a label, but no data.
o A long line can be continue by a null field (column):
Field2: blah blah blah
: blah blah blah
o On a continuation, the null field is an arbitrary number of leading white space,
a colon ':', a single blank or tab, followed by the continued text.
o Embedded newlines are indicated by the escape mechanism "\n". Similarly,
embedded tabs are indicated with "\t", returns with "\r".
o If the @titles array is empty, the field names ""Field_"NN" are used instead.
ShowRow
Fetch rows successively from one or more columns of data.
ShowRow $rewindflag, \$index, $col_array_1 [, $col_array_2, ...;]
The ShowRow subroutine returns a row of data from one or more columns of data. It is
designed to be used as a callback routine, within the ShowTable routine. It can be used
to select elements from one or more array reference arguments.
If passed two or more array references as arguments, elements of the arrays selected by
$index are returned as the "row" of data.
If a single array argument is passed, and each element of the array is itself an array,
the subarray is returned as the "row" of data.
If the $rewindflag flag is set, then the $index pointer is reset to zero, and "true" is
returned (a scalar 1). This indicates that the data is rewindable to the ShowTable
routines.
When the $rewindflag is not set, then the current row of data, as determined by $index is
returned, and $index will have been incremented.
An actual invocation (from ShowColumns) is:
ShowTable \@titles, \@types, \@lengths,
sub { &ShowRow( $_[0], \$current_row, $col_names, $col_types,
$col_lengths, \@col_attrs); };
In the example above, after each invocation, the $current_row argument will have been
incremented.
ShowTableValue
Prepare and return a formatted representation of a value. A value argument, using its
corresponding type, effective width, and precision is formatted into a field of a given
maximum width.
$fmt = ShowTableValue $value, $type, $max_width, $width, $precision, $showmode;
"width" => $width
$width The width of the current value. If omittied, $max_width is assumed.
"precision" => $precision
$precision
The number of decimal digits; zero is assumed if omittied.
"value" => $value
$value The value to be formatted.
$type The type name of the value; eg: "char", "varchar", "int", etc.
"maxwidth" => $max_width
$max_width
The maximum width of any value in the current value's column. If $width is zero
or null, $max_width is used by default. $max_width is also used as a minimum
width, in case $width is a smaller value.
$width The default width of the value, obtained from the width specification of the
column in which this value occurs.
$precision
The precision specification, if any, from the column width specification.
$showmode The mode of the output: one of "table", "list", "box", or "html". Currently,
only the "html" mode is significant: it is used to avoid using HTML tokens as
part of the formatted text and length calculations.
PlainText
$plaintext = &PlainText($htmltext);
&PlainText
This function removes any HTML formatting sequences from the input argument, or from $_ if
no argument is given. The resulting plain text is returned as the result.
VARIABLES
The following variables may be set by the user to affect the display (with the defaults
enclosed in square brackets [..]):
$Show_Mode [Box]
This is the default display mode when using ShowTable. The environment
variable, $ENV{'SHOW_MODE'}, is used when this variable is null or the empty
string. The possible values for this variable are: "Box", "List", "Table", and
"HTML". Case is insignificant.
$List_Wrap_Margin [2]
This variable's value determines how large a margin to keep before wrarpping a
long value's display in a column. This value is only used in "List" mode.
$Max_List_Width [80]
This variable, used in "List" mode, is used to determine how long an output line
may be before wrapping it. The environment variable, $ENV{'COLUMNS'}, is used
to define this value when it is null.
$Max_Table_Width ['']
This variable, when set, causes all tables to have their columns scaled such
that their total combined width does not exceed this value. When this variable
is not set, which is the default case, there is no maximum table width, and no
scaling will be done.
$No_Escape ['']
If set, allows embedded HTML text to be included in the data displayed in an
HTML-formatted table. By default, the HTML formatting characters ("<", ">", and
"&") occuring in values are escaped.
%URL_Keys In HTML mode, this variable is used to recognize which columns are to be
displayed with a corresponding hypertext anchor. See "ShowHTMLTable" for more
details.
@HTML_Elements
An array of HTML elements (as of HTML 3.0) used to recognize and strip for width
calculations.
$HTML_Elements
A regular expression string formed from the elements of @HTML_Elements.
INTERNAL SUBROUTINES
get_params
my $args = &get_params \@argv, \%params, \@arglist;
Given the @argv originally passed to the calling sub, and the hash of named parameters as
%params, and the array of parameter names in the order expected for a pass-by-value
invocation, set the values of each of the variables named in @vars.
If the only element of the @argv is a hash array, then set the variables to the values of
their corresponding parameters used as keys to the hash array. If the parameter is not a
key of the %params hash, and is not a key in the global hash %ShowTableParams, then an
error is noted.
When @argv has multiple elements, or is not a hash array, set each variable, in the order
given within @arglist, to the values from the @argv, setting the variables named by each
value in %params.
Variables may given either by name or by reference.
The result is a HASH array reference, either corresponding directly to the HASH array
passed as the single argument, or one created by associating the resulting variable values
to the parameter names associated with the variable names.
html_formats
($prefixes,$suffixes) = html_formats \@html_formats;
The html_format function takes an array reference of HTML formatting elements
\@html_formats, and builds two arrays of strings: the first: $prefixes, is an array of
prefixes containing the corresponding HTML formatting elements from \@html_formats, and
the second, $suffixes, containing the appropriate HTML closing elements, in the opposite
order.
The result is designed to be used as prefixes and suffixes for the corresponding titles
and column values.
The array \@html_formats contains lists of HTML formatting elements, one for each column
(either title or data). Each array element is a list of one or more HTML elements, either
given in HTML syntax, or as a "plain" name (ie: given as "\<ELEMENT\"> or plainly,
"ELEMENT"). Multiple elements are separated by a comma ','.
The resulting array of $prefixes contains the corresponding opening elements, in the order
given, with the proper HTML element syntax. The resulting array of $suffixes contains the
closing elements, in the opposite order given, with the proper HTML element syntax.
For example, if \@html_formats contains the two elements:
[ 'FONT SIZE=+2,BOLD', 'FONT COLOR=red,EM' ]
then the resulting two arrays will be returned as:
[ [ '<FONT SIZE=+2><BOLD>', '<FONT COLOR=red><EM>' ],
[ '</FONT></BOLD>', '</FONT></EM>' ] ]
calc_widths
($num_cols, $widths, $precision, $max_widths) = &calc_widths( $widthspec, $titles,
$rewindable, $row_sub, $fmt_sub, $types, $showmode, $max_width);
DESCRIPTION
calc_widths is a generalized subroutine used by all the ShowTable variant subroutines to
setup internal variables prior to formatting for display. Calc_widths handles the column
width and precision analysis, including scanning the data (if rewindable) for appropriate
default values.
The number of columns in the data is returned, as well as three arrays: the declared
column widths, the column precision values, and the maximum column widths.
RETURN VALUES
$num_cols is the number of columns in the data. If the data is not rewindable, this is
computed as the maximum of the number of elements in the $widthspec array and
the number of elements in the $titles array. When the data is rewindable, this
is the maximum of the number of columns of each row of data.
$widths is the column widths array ref, without the precision specs (if any). Each
column's width value is determined by the original $widthspec value and/or the
maximum length of the formatted data for the column.
$precision
is the precision component (if any) of the original $widthspec array ref. If
there was no original precision component from the $widthspec, and the data is
rewindable, then the data is examined to determine the maximum default
precision.
$max_widths
is the ref to the array of maximum widths for the given columns.
ARGUMENTS
$widthspec
A reference to an array of column width (or length) values, each given as an
integer, real number, or a string value of "width.precision". If a value is
zero or null, the length of the corresponding formatted data (if rewindable) and
column title length are used to determine a reasonable default.
If a column's width portion is a positive, non-zero number, then the column will
be this wide, regardless of the values lengths of the data in the column.
If the column's width portion is given as a negative number, then the positive
value is used as a minimum column width, with no limit on the maximum column
width. In other words, the column will be at least width characters wide.
If the data is not rewindable, and a column's width value is null or zero, then
the length of the column title is used. This may cause severe wrapping of data
in the column, if the column data lengths are much greater than the column title
widths.
$titles The array ref to the column titles; used to determine the minimum acceptable
width, as well as the default number of columns. If the $titles array is empty,
then the $widthspec array is used to determine the default number of columns.
$rewindable
A flag indicating whether or not the data being formatted is rewindable. If
this is true, a pass over the data will be done in order to calculate the
maximum lengths of the actual formatted data, using $fmt_sub (below), rather
than just rely on the declared column lengths. This allows for optimal column
width adjustments (ie: the actual column widths may be less than the declared
column widths).
If it is not desired to have the column widths dynamically adjusted, then set
the $rewindable argument to 0, even if the data is rewindable.
$row_sub The code reference to the subroutine which returns the data; invoked only if
$rewindable is non-null.
$fmt_sub The subroutine used to determine the length of the data when formatted; if this
is omitted or null, the length of the data is used by default. The $fmt_sub is
used only when the data is rewindable.
$types An array reference to the types of each of the value columns; used only when
$fmt_sub is invoked.
$showmode A string indicating the mode of the eventual display; one of four strings:
""box"", ""table"", ""list"", and ""html"". Used to adjust widths for
formatting requirements.
$max_width
The maximum width of the table being formatted. If set, and the total sum of
the individual columns exceeds this value, the column widths are scaled down
uniformly. If not set (null), no column width scaling is done.
putcell
$wrapped = &putcell( \@cells, $c, $cell_width, \@prefix, \@suffix, $wrap_flag );
Output the contents of an array cell at $cell[$c], causing text longer than $cell_width to
be saved for output on subsequent calls. Prefixing the output of each cell's value is a
string from the two-element array @prefix. Suffixing each cell's value is a string from
the two-element array @suffix. The first element of either array is selected when
$wrap_flag is zero or null, or when there is no more text in the current to be output.
The second element is selected when $wrap_flag is non-zero, and when there is more text in
the current cell to be output.
In the case of text longer than $cell_width, a non-zero value is returned.
Cells with undefined data are not output, nor are the prefix or suffix strings.
center
Center a string within a given width.
$field = center $string, $width;
max
Compute the maximum value from a list of values.
$max = &max( @values );
min
Compute the minum value from a list of values.
$min = &min( @values );
max_length
Compute the maximum length of a set of strings in an array reference.
$maxlength = &max_length( \@array_ref );
htmltext
Translate regular text for output into an HTML document. This means certain characters,
such as "&", ">", and "<" must be escaped.
$output = &htmltext( $input [, $allflag ] );
If $allflag is non-zero, then all characters are escaped. Normally, only the four HTML
syntactic break characters are escaped.
out
Print text followed by a newline.
out $fmt [, @text ];
put
Print text (without a trailing newline).
out $fmt [, @text ];

BUGS
o Embedded HTML is how the user can insert formatting overrides. However, the
HTML formatting techniques have not been given much consideration -- feel free
to provide constructive feedback.
