NAME

Test::Stream::Table - Format a header and rows into a table

DEPRECATED

This distribution is deprecated in favor of Test2, Test2::Suite, and Test2::Workflow.

See Test::Stream::Manual::ToTest2 for a conversion guide.

DESCRIPTION

This is used by some failing tests to provide diagnostics about what has gone wrong. This module is able to generic format rows of data into tables.

SYNOPSIS

use Test::Stream::Table qw/table/;

my @table = table(
    max_width => 80,
    collapse => 1, # Do not show empty columns
    header => [ 'name', 'age', 'hair color' ],
    rows => [
        [ 'Fred Flinstone',  2000000, 'black' ],
        [ 'Wilma Flinstone', 1999995, 'red' ],
        ...,
    ],
);

# The @table array contains each line of the table, no newlines added.
say $_ for @table;

This prints a table like this:

+-----------------+---------+------------+
| name            | age     | hair color |
+-----------------+---------+------------+
| Fred Flinstone  | 2000000 | black      |
| Wilma Flinstone | 1999995 | red        |
| ...             | ...     | ...        |
+-----------------+---------+------------+

EXPORTS

@rows = table(...)

The function returns a list of lines, lines do not have the newline \n character appended.

Options:

header => [ ... ]

If you want a header specify it here. This takes an arrayref with each columns heading.

rows => [ [...], [...], ... ]

This should be an arrayref containing an arrayref per row.

collapse => $bool

Use this if you want ot hide empty columns, that is any column that has no data in any row. Having a header for the column will not effect collapse.

max_width => $num

Set the maximum width of the table, the table may not be this big, but it will be no bigger. If none is specified it will attempt to fidn the width of your terminal and use that, otherwise it falls back to 80.

sanitize => $bool

This will sanitize all the data in the table such that newlines, control characters, and all whitespace except for ASCII 20 ' ' are replaced with escape sequences. This prevents newlines, tabs, and similar whitespace from disrupting the table.

mark_tail => $bool

This will replace the last whitespace character of any trailing whitespace with its escape sequence. This makes it easier to notice trailing whitespace when comparing values.

NOTE ON UNICODE/WIDE CHARATERS

Some unicode characters, such as 婧 (U+5A67) are wider than others. These will render just fine if you use utf8; as necessary, and Unicode::GCString is installed, however if the module is not installed there will be anomolies in the table:

+-----+-----+---+
| a   | b   | c |
+-----+-----+---+
| 婧 | x   | y |
| x   | y   | z |
| x   | 婧 | z |
+-----+-----+---+
