When you publish a post or update an already published post, this plugin will format the post’s content to certain typographic rules:
<ol>
<li>
All hyphens between two words (surrounded by spaces) will be transformed to m-dashes with the non-breaking spaces ahead of them.
</li>
<li>
All hyphens between digits (without spaces) will be transformed to n-dashes. But it tries to preserve phone numbers.
</li>
<li>
All spaces following these words will be replaced with the non-breaking spaces:
<ul>
<li>at</li>
<li>or </li>
<li>and</li>
<li>the</li>
<li>a</li>
<li>an</li>
<li>in</li>
<li>on</li>
<li>of</li>
<li>for</li>
<li>to</li>
<li>as</li>
<li>i</li>
<li>or</li>
<li>my</li>
</ul>
</li>
<li>
Double and more spaces are replaced with the single ones.
</li>
<li>
All misplaced spaces near dots, colons, semicolons, exclamation marks and question marks are fixed, where possible.
</li>
<li>
Composed words with hyphens in them (e.g. easy-to-use) will be wrapped in <code></code> tags.
</li>
<li>
<code><pre></pre></code> tag and its contents are preserved.
</li>
</ol>
<h4>Problems:</h4>
<ol>
<li>
The plugin will not mess with the HTML tags or other mark-up tags delimited with < and >. It will mess with the Javascript code and such constructions as:
<pre><code> [code]
 bla bla bla
 [/code]
</code></pre>
Though, since version 6, the mess is minimized for [code] and [video] tags.
</li>
<li>
The n-dash thing will mess up with the phone numbers that have only one hyphen in them. They will be confused with the value ranges.
</li>
</ol>

Zalomení is a WordPress plugin that automatically applies Czech typographic rules to post content, titles, comments, and widgets. It replaces ordinary spaces with non-breaking spaces wherever Czech typography forbids a line break, so editors don’t have to type them by hand.
Although Czech is the default, the plugin is structured around editable lists of prepositions, conjunctions, and abbreviations — so it can be adapted to Slovak (and other closely related languages) simply by adjusting those lists in the settings.
<h4>Maintainer</h4>
Zalomení is actively maintained by <a href="https://kybernaut.cz" rel="nofollow ugc">Karolína Vyskočilová</a> (WordPress.org username: <code>vyskoczilova</code>), an independent WordPress developer based in Czechia. She took the plugin over in 2026 after three years without updates, ran a full security audit, and now ships regular releases. The plugin was originally created by Honza Skýpala, whose work is gratefully acknowledged.
<h4>What the plugin handles</h4>
<ul>
<li>Prepositions — single-letter prepositions like k, s, v, z must not appear at the end of a line.</li>
<li>Conjunctions — single-letter conjunctions like a, i, o, u.</li>
<li>Abbreviations — common Czech abbreviations (e.g. např., tj., tzv.).</li>
<li>Numbers and units — prevents breaks between a number and its unit (e.g. 5 kg, 10 Kč).</li>
<li>Number formatting — keeps formatted numbers together (e.g. phone numbers like 800 123 456).</li>
<li>Ordinal numbers — prevents breaks after ordinals, especially in dates (e.g. 1. ledna).</li>
<li>Scales and ratios — keeps expressions like 1 : 50 000 on one line.</li>
<li>Custom terms — user-defined multi-word terms that should never be broken across lines.</li>
</ul>
All options are configurable under Settings → Reading. The plugin exposes a <code>zalomeni_filtry</code> filter so developers can add or remove the WordPress hooks Zalomení applies to.
