Hi,
inspired by Paul Isambert's very nice article in the last MAPS(1) and also in
tugboat 31:3 (2) I'd like to post a LaTeX/LuaTeX example. It shows all the
hyphenation points of a text. It's also wikified at
http://wiki.luatex.org/index.php/Show_the_hyphenation_points
Please correct any errors at the wiki page, thanks!
Thanks for the document, Patrick.
How could be the hyphenation points marked in red?
I guess that red hyphenation points would be easier to be noticed.
Thanks for your help,
Pablo
