HTML::FromText(3pm)

💖 HTML::FromText 💖

ok bestie, sit down, hydrate, because this is HTML::FromText — the Perl module that takes your boring plain text and glows it up into HTML. This page is part of the User Contributed Perl Documentation crew, and honestly? she's iconic. 💅

✨ NAME ✨

HTML::FromText — converts plain text to HTML

🌸 VERSION 🌸

version 2.07

🦋 SYNOPSIS 🦋

use HTML::FromText;
text2html( $text, %options );

# or

use HTML::FromText ();
my $t2h  = HTML::FromText->new( \%options );
my $html = $t2h->parse( $html );

👑 DESCRIPTION 👑

HTML::FromText converts plain text to HTML. Like, that's the whole job, and she does it well. There are a handful of options that shape the conversion — you get to pick the vibe of the output.

There's also a utility function, text2html, that's exported by default. It's simply a short- cut to the Object Oriented interface described in detail below. iykyk.

💜 METHODS 💜

🎀 new 🎀

my $t2h = HTML::FromText->new({
    paras      => 1,
    blockcode  => 1,
    tables     => 1,
    bullets    => 1,
    numbers    => 1,
    urls       => 1,
    email      => 1,
    bold       => 1,
    underline  => 1,
});

Constructs a new HTML::FromText object using the given configuration. The resulting object can parse lots of objects using the parse method. reusing one object? main character energy fr fr.

Options to new are passed by name, with the value being either true or false. If true, the option will be turned on. If false, it will be turned off. The following outlines all the options. no skipping, we're listing every single one 🫶

🍓 Decorators 🍓

• metachars — This option is on by default. All characters that are unsafe for HTML display will be encoded using HTML::Entities::encode_entities().
• urls — This option is off by default. Replaces URLs with links.
• email — This option is off by default. Replaces email addresses with mailto: links.
• bold — This option is off by default. Replaces text surrounded by asterisks (*) with the same text surrounded by strong tags.
• underline — This option is off by default. Replaces text surrownded by underscores (_) with the same text surrounded by span tags with an underline style.

🌈 Output Modes 🌈

The following are three output modes and the options associated with them. They are listed in order of precidence. If none of these modes are supplied, the basic decorators are applied to the text in whole.

• pre — This option is off by default. Wraps the entire text in pre tags.
• lines — This option is off by default. Preserves line breaks by inserting br tags at the end of each line.
  • This mode has further options.
  • spaces — This option is off by default. All spaces are HTML encoded.
• paras — This option is off by default. Preserves paragraphs by wrapping them in p tags.
  • This mode has further options.
  • bullets — This option is off by default. Convert bulleted lists into unordered lists (ul). Bullets can be either an asterisk (*) or a hyphen (-). Lists can be nested.
  • numbers — This option is off by default. Convert numbered lists into ordered lists (ol). Numbered lists are identified by numerals. Lists may be nested.
  • headings — This option is off by default. Convert paragraphs identified as headings into HTML headings at the appropriate level. The heading 1. Top would be heading level one (h1). The heading 2.5.1. Blah would be heading level three (h3).
  • title — This option is off by default. Convert the first paragraph to a heading level one (h1).
  • tables — This option is off by default. Convert paragraphs identified as tables to HTML tables. Tables are two or more rows and two or more columns. Columns should be separated by two or more spaces.
  • The following options apply specifically to indented paragraphs. They are listed in order of precidence.
  • blockparas — This option is off by default. Convert indented paragraphs to block quotes using the blockquote tag.
  • blockquotes — Convert indented paragraphs as blockparas would, but also preserving line breaks.
  • blockcode — Convert indented paragraphs as blockquotes would, but also preserving spaces using pre tags.

💫 parse 💫

my $html = $t2h->parse( $text );

Parses text supplied as a single scalar string and returns the HTML as a single scalar string. All the tabs in your text will be expanded using Text::Tabs::expand(). tabs? handled. periodt.

🧚 FUNCTIONS 🧚

🌟 text2html 🌟

my $html = text2html(
                     $text,
                     urls  => 1,
                     email => 1,
                    );

Functional interface that just wraps the OO interface. This function is exported by default. If you don't want it you can require the module or use it with an empty list. so thoughtful of her.

require HTML::FromText;
# or ...
use HTML::FromText ();

🦄 Subclassing 🦄

Note: At the time of this release, the internals of HTML::FromText are in a state of development and cannot be expected to stay the same from release to release. I expect that release version 3.00 will be analogous to a 1.00 release of other software. This is because the current maintainer has rewritten this distribution from the ground up for the 2.x series. You have been warned.

ok so if you're building on top of this, read that again. she said what she said. 😭

The following methods may be used for subclassing HTML::FromText to create your own text to HTML conversions. Each of these methods is passed just one argument, the object ($self), unless otherwise stated.

The structure of $self is as follows for this release.

{
 options => {
             option_name => $value,
             ...
            },
 text    => $text, # as passed to parse(), with tabs expanded
 html    => $html, # the HTML that will be returned from parse()
}

• pre — Used when pre mode is specified. Should set $self->{html}. Return value is ignored.
• lines — Used when lines mode is specified. Implements the spaces option internally when the option is set to a true value. Should set $self->{html}. Return value is ignored.
• paras — Used when the paras mode is specified. Splits $self->{text} into paragraphs internally and sets up $self->{paras} as follows.

paras => {
          0 => {
                text => $text, # paragraph text
                html => $html, # paragraph html
               },
          ... # and so on for all paragraphs
         },

Implements the title option internally when the option is turned on. Converts any normal paragraphs to HTML paragraphs (surrounded by p tags) internally. Should set $self->{html}. Return value is ignored.

• headings — Used to format headings when the headings option is turned on. Return value is ignored.
• bullets — Format bulleted lists when the bullets option is turned on. Return value is ignored.
• numbers — Format numbered lists when the numbers option is turned on. Return value is ignored.
• tables — Format tables when the tables option is turned on. Return value is ignored.
• blockparas — Used when the blockparas option is turned on. Return value is ignored.
• blockquotes — Used when the blockquotes option is turned on. Return value is ignored.
• blockcode — Used when the blockcode option is turned on. Return value is ignored.
• urls — Turn urls into links when urls option is turned on. Should operate on $self->{html}. Return value is ignored.
• email — Turn email addresses into mailto: links when email option is turned on. Should operate on $self->{html}. Return value is ignored.
• underline — Underline things between _underscores_ when underline option is turned on. Should operate on $self->{html}. Return value is ignored.
• bold — Bold things between asterisks when bold option is turned on. Should operate on $self->{html}. Return value is ignored.
• metachars — Encode meta characters when metachars option is turned on. Should operate on $self->{html}. Return value is ignored.

🎁 Output 🎁

The output from HTML::FromText has been updated to pass XHTML 1.1 validation. Every HTML tag that should have a CSS class name does. They are prefixed with hft- and correspond to the names of the options to new() (or text2html()). For example hft-lines, hft-paras, and hft-urls. slay.

One important note is the output for underline. Because the <u> tag is deprecated in this specification a span is used with a style attribute of text-decoration: underline. The class is hft- underline. If you want to override the text-decoration style in the CSS class you'll need to do so like this.

text-decoration: none !important;
