Editing Syllabification (section)

=== In TeX ===
Ports of the TeX hyphenation algorithm are available as libraries for several programming languages, including [[Haskell (programming language)|Haskell]], [[JavaScript]], [[Perl]], [[PostScript]], [[Python (programming language)|Python]], [[Ruby (programming language)|Ruby]], [[C Sharp (programming language)|C#]], and TeX can be made to show hyphens in the log by the command <code>\showhyphens</code>.

In [[LaTeX]], hyphenation correction can be added by users by using:

<pre>\hyphenation{words}</pre>

The <code>\hyphenation</code> command declares allowed hyphenation points in which words is a list of words, separated by spaces, in which each hyphenation point is indicated by a <code>-</code> character. For example,

<pre>\hyphenation{fortran er-go-no-mic}</pre>

declares that in the current job "fortran" should not be hyphenated and that if "ergonomic" must be hyphenated, it will be at one of the indicated points.<ref>{{cite web |url= http://noodle.med.yale.edu/latex/latex2e-html/ltx-244.html |title= \hyphenation |work= Hypertext Help with LaTeX |publisher= Yale Image Processing and Analysis Group |first1=Sheldon |last1=Green |date=5 Jun 1995 |url-status=live |archive-url=https://web.archive.org/web/20231127043725/http://noodle.med.yale.edu/latex/latex2e-html/ltx-244.html |archive-date= Nov 27, 2023 }}</ref>

However, there are several limits. For example, the stock <code>\hyphenation</code> command accepts only [[ASCII]] letters by default and so it cannot be used to correct hyphenation for words with non-ASCII characters (like ''ä'', ''é'', ''ç''), which are very common in many  languages. Simple workarounds exist, however.<ref>{{cite web |url= https://texfaq.org/FAQ-hyphenaccents |title=Accented words aren't hyphenated |work=TeX FAQ |url-status=live |archive-url=https://web.archive.org/web/20231128190033/https://texfaq.org/FAQ-hyphenaccents |archive-date= Nov 28, 2023 }}</ref><ref>{{cite web |url= https://texfaq.org/FAQ-hyphen |title=How does hyphenation work in TeX? |work=TeX FAQ |url-status=live |archive-url= https://web.archive.org/web/20231127043729/https://texfaq.org/FAQ-hyphen |archive-date= Nov 27, 2023 }}</ref>
