This implementation is a port of Ned Batchelder’s <a href="http://nedbatchelder.com/code/modules/hyphenate.html">Python version</a>. I have added little to their work. Accordingly, I take little credit.</p><p>I originally put together this module to handle hyphenation for my web-based book <a href="http://practicaltypography.com">Butterick’s Practical Typography</a> (which I made with Racket & Scribble). Though support for CSS-based hyphenation in web browsers is <a href="http://caniuse.com/#search=hyphen">still iffy</a>, soft hyphens work reliably well. But putting them into the text manually is a drag. Thus a module was born.</p><h3>1<tt> </tt><a name="(part._.Installation)"></a>Installation</h3><p><div class="SIntrapara">At the command line:

This is good policy. Perfect hyphenation — that is, hyphenation that represents an exact linguistic syllabification of each word — is superfluous for typesetting. Hyphenation simply seeks to mark possible line-break and page-break locations for whatever layout engine is drawing the text. The ultimate goal is to permit more even text flow. Like horseshoes and hand grenades, close is good enough. And a word wrongly hyphenated is more likely to be noticed by a reader than a word inefficiently hyphenated.</p><p>For this reason, certain words can’t be hyphenated algorithmically, because the correct hyphenation depends on meaning, not merely on spelling. For instance:</p><p><table cellspacing="0" class="RktBlk"><tr><td><p>Example:</p></td></tr><tr><td><blockquote class="SCodeFlow"><table cellspacing="0" class="RktBlk"><tr><td><span class="stt">> </span><span class="RktPn">(</span><span class="RktSym"><a href="index.html#%28def._%28%28lib._hyphenate%2Fmain..rkt%29._hyphenate%29%29" class="RktValLink" data-pltdoc="x">hyphenate</a></span><span class="hspace"> </span><span class="RktVal">"adder"</span><span class="RktPn">)</span></td></tr><tr><td><p><span class="RktRes">"adder"</span></p></td></tr></table></blockquote></td></tr></table></p><p>This is the right result.
