The property hyphens controls whether hyphenation
is allowed to create opportunities to wrap within a line of text: the value
none instructs never to hyphenate, while manual tells
Prince to only hyphenate when there are characters inside the word that explicitly
suggest hyphenation opportunities, such as e.g. "soft hyphens" (represented either
by the Unicode character U+00AD or the HTML entity ­).
With the value auto, words may be broken at appropriate hyphenation
points as determined automatically by the language-appropriate hyphenation resources,
or by hyphenation characters in a word. The default value is manual -
to enable automatic hyphenation in a body of text, the value auto has
to be declared.
The character shown at the end of a line when the word is hyphenated can be
specified with the prince-hyphenate-character
property.
Fine-tuning of hyphenation can be done with the
prince-hyphenate-after and
prince-hyphenate-before properties to determine
the minimum number of letters in a word that may be moved to the next line or
that may be left at the end of a line when the word is hyphenated.
The prince-hyphenate-lines property is used to
determine the maximum number of consecutive lines that may end with a hyphenated
word.
Prince uses the hyphenation patterns from the CTAN archive - the full archive is
accessible here.
The default hyphenation patterns can be found in the installed hyph.css file,
located in the default style sheets location (see Installation Layout).
Hyphenation patterns for the following languages are provided:
| da | Danish |
| de | German |
| en-US | English |
| es | Spanish |
| fi | Finnish |
| fr | French |
| is | Icelandic |
| it | Italian |
| lt | Lithuanian |
| pl | Polish |
| pt | Portuguese |
| ru | Russian |
| sl | Slovenian |
| sv | Swedish |
A special case is Thai hyphenation, supported thanks to the LibThai package.
To add hyphenation patterns for other languages, download them from the
CTAN
archive. Save the files for the chosen language without the .txt
extension, and link to the pattern file (with the .pat extension) with
the prince-hyphenate-patterns CSS property. Prince determines
which language to use for hyphenation with the help of the :lang() CSS
selector, which in turn checks the lang or xml:lang attributes
of the document:
:lang(en-GB) {
prince-hyphenate-patterns: url("hyph-en-gb.pat");
}<span lang="en-GB">supercalifragilisticexpialidocious</span>
