BorderStyleRole::Source::ASCIIArt - Get border characters from ASCII art

VERSION

This document describes version 3.0.2 of BorderStyleRole::Source::ASCIIArt (from Perl distribution BorderStyle), released on 2022-02-14.

SYNOPSIS

 package BorderStyle::YourStyle;
 use strict;
 use warnings;
 use utf8;
 use Role::Tiny::With;
 with 'BorderStyleRole::Source::ASCIIArt';

 our $PICTURE = <<'_';
 ┌───────┬───┬───┐'
 │ ..... │ . │ . │'
 │ ..... ├───┼───┤'
 │ ..... │ . │ . │'
 │ ..... ├───┴───┤'
 │ ..... │ ..... │'
 ├───┬───┤ ..... │'
 │ . │ . │ ..... │'
 └───┴───┴───────┘'
 _

 our %BORDER = (
     v => 3,
     summary => 'Summary of your style',
     utf8 => 1,
 );
 1;

DESCRIPTION

To define border characters, you declare $PICTURE package variable in your border style class, using a specific ASCII art as shown in the Synopsis. You then modify the border characters (the lines, not the spaces and the dots) according to your actual style. This is a convenient way to define border styles instead of declaring the characters specifically using a hash. Note that empty border characters are not supported by this role.

For more complex border styles, you define @PICTURES instead, with each element being a hash:

 # this style is single bold line for header rows, single line for data rows.
 our @PICTURES = (
     {
         # imagine every line is a header-row separator line (theoretically, the
         # top and bottom lines won't ever be used as separator though)
         for_header_data_separator => 1,
         picture => <<'_',
 ┍━━━━━━━┯━━━┯━━━┑'
 ╿ ..... ╿ , ╿ . ╿'
 ╿ ..... ┡━━━╇━━━┫'
 ╿ ..... ╿ . ╿ . ╿'
 ╿ ..... ┡━━━┻━━━┫'
 ╿ ..... ╿ ..... ╿'
 ┡━━━┯━━━┩ ..... ╿'
 ╿ . ╿ . ╿ ..... ╿'
 ┗━━━┻━━━┻━━━━━━━┛'
 _
     },
     {
         for_header_row => 1,
         picture => <<'_',
 ┏━━━━━━━┳━━━┳━━━┓'
 ┃ ..... ┃ , ┃ . ┃'
 ┃ ..... ┣━━━╋━━━┫'
 ┃ ..... ┃ . ┃ . ┃'
 ┃ ..... ┣━━━┻━━━┫'
 ┃ ..... ┃ ..... ┃'
 ┣━━━┳━━━┫ ..... ┃'
 ┃ . ┃ . ┃ ..... ┃'
 ┗━━━┻━━━┻━━━━━━━┛'
 _
     },
     {
         picture => <<'_',
 ┌───────┬───┬───┐'
 │ ..... │ . │ . │'
 │ ..... ├───┼───┤'
 │ ..... │ . │ . │'
 │ ..... ├───┴───┤'
 │ ..... │ ..... │'
 ├───┬───┤ ..... │'
 │ . │ . │ ..... │'
 └───┴───┴───────┘'
 _
     },
 );

Internally, some characters from the ASCII art will be taken and put into %CHARS or @MULTI_CHARS and this role's "get_border_char()" will pass to BorderStyleRole::Source::Hash's.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.

When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature.
