This is a port of wp-Typography for Kirby CMS. Based on the PHP_Typography class, this plugin enhances the typography of you kirby-powered website. Think of it a more advanced alternative to the built-in SmartyPants parser.

Current version: 1.0.0-beta1

Table of Contents

1 Key Features

  • Hyphenation: Hyphenate text, very handy for justified text or languages with very long words, but also for English. Supports a large number of languages and offers fine-grained control over hyphenation.
  • Smart Replacements: Includes Smart quotes (i.e. „Curly Quotes“, «Guillemets», »Chevrons« or German „Gänsefüßchen“) and smart ordinal suffixes.
  • CSS Hooks: Add <span class="[…]"> tags around characters like ampersands, CAPITALIZED WORDS etc.
  • Hanging Punctuation: Add the twinkle of the print-era to your site.
  • Wraps URLs: Prevents long URLs from overflowing their container element on small screens.
  • Smart Math: Converts mathematical symbols into their correct counterpart. E.g. (2x6)/3=4 becomes (2×6)÷3=4.
  • Caching: Processing text like this plugin does is a very performance-hungry task. So the results are always cached, even if Kirby’s cache option is turned off. Cache will automatically be updated, if you change your content or update the plugin. It also comes with a Dashboard Widget, so you can flush the cache from your panel.

… and basically every other feature of wp-Typography :-)

2 Download and Installation

2.1 Requirements

  • PHP 5.4.0+ with multibyte extension (mbstring)
  • Kirby 2.3.0+ (not compatible with Kirby 3)

2.2 Kirby CLI

If you’re using the Kirby CLI, you need to cd to the root directory of your Kirby installation and run the following command:

kirby plugin:install fabianmichael/kirby-typography

This will download and copy Kirby-Typography into site/plugins/typography.

2.3 Git Submodule

To install this plugin as a git submodule, execute the following command from the root of your kirby project:

$ git submodule add site/plugins/typography

2.4 Copy and Paste

  1. Download the contents of this repository as ZIP-file.
  2. Rename the extracted folder to typography and copy it into the site/plugins/ directory in your Kirby project.

3 Usage

The plugin is enabled by default and replaces the SmartyPants parser of your Kirby installation. That means, typographic enhancements are applied to Kirbytext by default.

I tried to setup sane defaults, but you might have different requirements for your site. You can change any of the plugin’s settings in your config.php file.

3.1 CSS and JavaScript Setup

CSS: Not all features of the plugin need extra CSS rules, but for stuff like hanging punctuation, and character styling to work properly, it is recommended or even necessary to add the plugin’s CSS file to your site. Add <?= css('assets/plugins/typography/css/typography.css') ?> to your template or – even better – copy the rules to your own stylesheet. Note, that some features like hanging punctuation should be tuned in accordance to the font you have chosen.

JavaScript: Hyphenation works by inserting invisible so-called »shy hyphens« (&shy;) into works, telling the browser where a word may be hyphenated. Unfortunately, these invisible characters stay in the text, when it is copied from your site. To keep copied text easily editable, it is recommended (though not mandatory) to also include the supplied JavaScript file to your code. Just add <?= js('assets/plugins/typography/js/dist/copyfix.min.js') ?> into to your template.

4 Configuration

You can find a description of all available configuration options below. Customization works just like with any other configuration of Kirby. Your can read more about configuration in the Kirby docs. The default settings of this plugin were chosen for United States (US) English.

4.1 Localization for Multilingual Sites

If your Kirby installation is configured for multiple languages, you might want to use different settings for every language. In this case, you can define a common baseline of settings – shared by all languages – in your config file. Use the language files in site/languages/ to define localized versions of your settings. Note, that in the language files, settings need to be configured with l::set(), because those localizations are treated as language variables:

# site/config/config.php
c::set('typography.class.ampersand', 'ch-amp'); // CSS classes are most likely shared across languages
# site/languages/fr.php
l::set('typography.quotes.primary', 'doubleGuillemetsFrench'); // Quote styles are language-specific …
l::set('typography.quotes.secondary', 'doubleCurled');
l::set('typography.hyphenation.language', 'fr'); // … and so are hyphenation rules

# site/languages/de.php
l::set('typography.quotes.primary', 'doubleLow9Reversed');
l::set('typography.quotes.secondary', 'singleLow9Reversed');
l::set('typography.hyphenation.language', 'de');

At the end of this document, you can find a list of recommended settings for different languages, you can use as a starting point for your own configuration.

4.3 Smart Quotes

Option Default value Description
typography.quotes true Transform straight quotes [ ' " ] to typographically correct characters.
typography.quotes.primary 'doubleCurled' Primary quotes style.
typography.quotes.secondary 'singleCurled' Secondary quotes style (for nested quotations).

Available Styles for Smart Quotes:

'doubleGuillemetsReversed' »foo«
'singleGuillemets' ‹foo›
'singleGuillemetsReversed' ›foo‹
'cornerBrackets' 「foo」
'whiteCornerBracket' 『foo』

4.4 Smart Character Replacements

Option Default value Description
typography.dashes true Transform minus-hyphens [ - -- ] to contextually appropriate dashes, minus signs, and hyphens [ – — − ‐ ]. 'em' Sets the style of smart dashes. Alternative value: 'em'.1
typography.dashes.spacing true Force thin spaces between em & en dashes and adjoining words.
typography.diacritics false Force diacritics where appropriate (i.e. creme brulee becomes crème brûlée).
typography.diacritics.language en-US Language for diacritic replacements. Language definitions will purposefully not process words that have alternate meaning without diacritics like resume & résumé, divorce & divorcé, and expose & exposé. Currently available options are only 'en-US' and 'de-DE'.
typography.diacritics.custom [] Custom diacritic word replacements: Takes an associative array with the searches as keys and the replacements as values. Note, that this is case-sensitive.
typography.ellipses true Transform three periods [ ... ] to ellipses [ … ].
typography.marks true Transform registration marks [ (c) (r) (tm) (sm) (p) ] to proper characters [ © ® ™ ℠ ℗ ].
typography.ordinal.suffix true Transform ordinal suffixes [ 1st ] to pretty ordinals [ 1st ].
typography.math true Transforms math symbols [ (2x6)/3=4 ] to correct symbols [ (2×6)÷3=4 ].
typography.fractions true Transform fractions [ 1/2 ] to pretty fractions [ 12 ].
typography.exponents true Transform exponents [ 3^2 ] to pretty exponents [ 32 ].

1) In the US, the em dash — with no or very little spacing — is used for parenthetical expressions, while internationally, the en dash – with spaces – is more prevalent.

2) Some fonts support smart fractions via an OpenType feature called “frac”, but is has to be enabled manually by declaring the font-feature-settings property in CSS. As of 2016, this is not supported by all major browsers. If you need this to work in everywhere, you should not rely on the OpenType feature and leave this setting turned on. The only exception where you really should disable this feature are monospaced fonts, because using smaller digits will break the fixed-width grid, your letters are sitting on. Details on browser support for the frac feature can be found at The State of Web Type and Can I use.

4.5 Smart Spacing

Option Default value Description
typography.wordspacing.singlecharacter true Enable forcing single character words to next line with the insertion of &nbsp; (no-break space).
typography.fraction.spacing true Inserts a no-break space into fractions to prevent wrapping [ 5 12 ].
typography.punctuation.spacing.french false Enable extra whitespace before certain punctuation marks, as is the French custom.
typography.units.spacing true Keep values and units together [ 12 cm ].
typography.units.custom [] Additional units to match (Kirby-Typography already recognizes a with a large amount of different units).
typography.dewidow true Prevent widows.
typography.dewidow.maxlength 5 Only protect widows with x or fewer letters.
typography.dewidow.maxpull 5 Pull at most x letters from the previous line to keep the widow company.
typography.wrap.hardhyphens true Enable wrapping after hard hyphens. Adds zero-width spaces after hard hyphens (like in “zero-width”).
typography.wrap.url true Enable wrapping of long URLs. Adds zero-width spaces throughout the URL. true Enable wrapping of long emails. Adds zero-width spaces throughout the email.
typography.wrap.url.minafter 5 Keep at least the last x characters of a URL together. ['local', 'onion', 'exit', 'tor', 'test', 'example'] The parser looks for domains in your content, based on a list of all valid Top-Level-Domains (updated and cached automatically once a week). Use this option to define additional domains, the parser should look for. true Remove superfluous whitespace from your content. false Enable to use true no-break narrow space (U+202F) instead of regular no-break space (&nbsp;). Disabled by default, because this glyph is missing in most fonts. Make sure, that your

4.6 Character Styling and Hanging Punctuation

The following options add <span> tags around certain parts of your content to create CSS hooks, allowing you to style specific parts of your text.

Option Default value Description false Wrap ampersands [ & ] with a <span> tag. true Wrap words in ALL CAPS with a <span> tag. false Wrap numbers with a <span> tag. false Enable hanging punctuation. Also see the included stylesheet to see how this works. true Wrap initial quotes with a <span> tag.

typography.hyphenation.exceptions [] Exception List (array): Mark allowed hyphenations with "-" (e.g. typo-graphy).

3) Hyphenation rules are available for the following languages: af, hy, eu, bg, ca, zh-Latn, hr, cs, da, nl, en-GB, en-US, et, fi, fr, gl, ka, de, de-1901, grc, el-Mono, el-Poly, hu, is, id, ia, ga, it, la, la-classic, lv, lt, mn-Cyrl, no, pl, pt, ro, ru, sa, sr-Cyrl, sh-Cyrl, sh-Latn, sk, sl, es, sv, th, tr, tk, uk, cy

4.8 CSS Classes

Some of the options above add <span> tags around single characters or sequences of characters, so you hook into their presentation via good ol’ CSS. If you don’t like the rather long class names I have chosen as default, feel free to change ’em to whatever you like by settings the options below:

typography.class.pull.double 'pull--doubleQuote'
typography.class.ordinal.suffix 'char--ordinalSuffix'

5 Recommended Settings for Different Languages

The following recommendations are based on common typographic conventions of those languages. That does not mean, that you have to stick to them, but their make a good starting point for your own settings. Is your language missing in this list? Feel free to create an issue or pull request and I will add settings for your language to the list.

Important: If your site is multilingual, you need to define those settings in site/languages/[language code].php, using l::set() instead of c::set, if you want to use different settings per language.

French (France):

  'typography.punctuation.spacing.french' => true,
  ''               => 'em', // cadratin ('en' for demi-cadratin)
  'typography.quotes.primary'             => 'doubleGuillemetsFrench',
  'typography.quotes.secondary'           => 'doubleCurled',
  'typography.hyphenation.language'       => 'fr',

German (Germany):

  ''         => 'en',
  'typography.quotes.primary'       => 'doubleLow9Reversed',
  'typography.quotes.secondary'     => 'singleLow9Reversed',
  'typography.hyphenation.language' => 'de',

Note: In books, sometimes Chevrons [ »foo« ] are used as quotation marks instead. Use doubleGuillemetsReversed and singleGuillemetsReversed if you prefer that style.
