Description

Terminal::Table provides a simple and also a advance way generate table output in terminals. It support multi line table cell. You can create your own style for your table, and you can colour your table content. Also the module has common style pre-defined.

Usage

link:README.zh.adoc[中文帮助]

== Interface

=== High Level Interface

The simple way to use Terminal::Table is use API below:

These subs want a two-dimension array of string. It uses pre-defined style. Default is Style::Default::ASCII, also you can their low case name such as 'ascii'.

• print-table(@data, @max-widths = [], :$style=Style::Default::ASCII)

Print table to stdout.

• array-to-table(@data, @max-widths = [], :$style=Style::Default::ASCII)

Return an array contain table data;

• create-generator(@data, :$style=Style::Default::ASCII);

Return an generator base on the @data.

==== Pre-defined Style

[source,raku]

enum Style::Default is export << :NONE('none') :ASCII('ascii') :SPACE('space') :DOT('dot') :SINGLE('single') :DOUBLE('double') :ROUND('round') :OTHER('other') # other is use for self-defined-style

;

Example

High Level Interface

[source, raku]

use Terminal::Table;

my @data = [ [ "Language", "Example" ], [ "Chinese", "你吃饭了吗？\n你好！\n你从哪里来？" ], [ "English", "Nice to meet you!\nWhere are you from?" ], [ "Janpanese","ありがとうございます。\nいただきます！"], [ "Korean", "안녕하세요！"], ];

print-table(@data);

It will output:

Low Level Interface

[source, raku]

#!/usr/bin/env raku

use v6; use Terminal::Table::Generator; use Terminal::Table::Style;

my $g = Generator.new( style => Style.new( corner-style => Style::Corner.double(), line-style => Style::Line.double(), content-style => Style::Content.space(), ) );

$g.add-cell('Language'); $g.add-cell('Example'); $g.add-cell('Country'); $g.end-line; $g.add-cell('Chinese'); $g.add-cell("你吃饭了吗？\n你好！\n你从哪里来？"); $g.add-cell('China'); $g.end-line; $g.add-cell('Janpanese'); $g.add-cell(' ありがとうございます。 いただきます！'); $g.add-cell('Janpa'); $g.end-line; $g.add-cell('English'); $g.add-cell('Nice to meet you! Are you ok? Where are you from ?'); $g.add-cell('American、England、Australian .etc'); $g.end-line; $g.add-cell('Korean'); $g.add-cell('안녕하세요！'); $g.add-cell('Korea'); $g.end-line; $g.generator().generate().print();

It will output:

Generator join and colour

Terminal::Table use https://github.com/tadzik/Terminal-ANSIColor[Terminal::ANSIColor] for colour process.

[source, raku]

#!/usr/bin/env raku

use Terminal::Table::Style; use Terminal::Table::Generator;

my $gl = Generator.new( style => Style.new( corner-style => Style::Corner.double(), line-style => Style::Line.double(), content-style=> Style::Content.space(), ) );

for 1 .. 9 -> \x { for 1 .. x -> \y { $gl.add-cell("{y} x {x} = {x * y}"); } $gl.end-line(); }

my $gr = Generator.new( style => Style.new( corner-style => Style::Corner.single(), line-style => Style::Line.dot(), content-style=> Style::Content.space(), ) );

my @data;

for reverse 1 .. 9 -> \x { @data.push([ "{.Int} x {x} = {x * .Int}" for 1 .. x ]); }

$gr.from-array(@data); $gl.join($gr, :replace-style);

my $g = $gl.generator().generate();

$g.colour(0, 0, Color::String.new(color => )); $g.colour(8, $, Color::String.new(color => )) for ^9; $g.colour(9, $, Color::String.new(color => )) for ^9; $g.print(:coloured);

It will output:

Irregular shape

[source, raku]

#!/usr/bin/env raku

use v6; use Terminal::Table;

constant SIZE = 22;

my $g = create-generator([ 'C' xx SIZE, 'C' xx SIZE, 'C' xx SIZE, 'C' xx SIZE, 'C' xx SIZE, 'C' xx SIZE, 'C' xx SIZE, ]);

$g.generate;

my &hide = -> $x, $y { my ($r, $c) = ($g.row-count() * 2, $g.col-count($x) * 2); my ($rx, $ry) = ($x * 2, $y * 2);

my $top = $rx == 0 || $g.is-hidden($rx - 1, $ry + 1);
my $top-left = ($rx == 0 || $ry == 0) || $g.is-hidden($rx - 1, $ry - 1);
my $top-right = ($rx == 0 || $ry + 2 == $c) || $g.is-hidden($rx - 1, $ry + 3);
my $bottom = ($rx + 2 == $r) || $g.is-hidden($rx + 3, $ry + 1);
my $bottom-left = ($rx + 2 == $r || $ry == 0) || $g.is-hidden($rx + 3, $ry - 1);
my $bottom-right = ($rx + 2 == $r || $ry + 2 == $c) || $g.is-hidden($rx + 3, $ry + 3);
my $left = $ry == 0 || $g.is-hidden($rx + 1, $ry - 1);
my $right = ($ry + 2 == $c) || $g.is-hidden($rx + 1, $ry + 3);

if $top && $top-left && $left {
    $g.hide($rx, $ry, :replace-with-space);
}
if $top {
    $g.hide($rx, $ry + 1, :replace-with-space);
}
if $top && $top-right && $right {
    $g.hide($rx, $ry + 2, :replace-with-space);
}
if $left {
    $g.hide($rx + 1, $ry, :replace-with-space);
}
if $right {
    $g.hide($rx + 1, $ry + 2, :replace-with-space);
}
if $left && $bottom-left && $bottom {
    $g.hide($rx + 2, $ry, :replace-with-space);
}
if $bottom {
    $g.hide($rx + 2, $ry + 1, :replace-with-space);
}
if $right && $bottom-right && $bottom {
    $g.hide($rx + 2, $ry + 2, :replace-with-space);
}
$g.hide($rx + 1, $ry + 1, :replace-with-space);

};

&hide(1, 13 + $) for ^8; &hide($, 13) for 2 .. 5; &hide($, 14) for 2 .. 5; &hide(5, 13 + $) for ^8; &hide($, 20) for 3 .. 4; &hide($, 19) for 3 .. 4; &hide(3, 15 + $_) for ^5;

&hide(1, 3 + $) for ^8; &hide($, 3) for 2 .. 5; &hide($, 4) for 2 .. 5; &hide($, 10) for 2 .. 3; &hide($, 9) for 2 .. 3; &hide(3, 4 + $) for ^6; &hide(5, 2 + $_) for ^4;

$g.print;

It will output:
