LuaTeX; widows; orphans; LuaTeX; vdova; sirotek
Balíček lua-widow-control pro LuaTeX/LuaLaTeX/ConTeXt/OpTeX odstraňuje vdovy a sirotky bez dalšího zásahu uživatele. Využívá přitom sílu LuaTeXu a přitom nenatahuje žádné vertikální mezery a ani nezkracuje stránky nebo sloupce. Namísto toho balíček automaticky prodlužuje některý z odstavců na té stránce nebo sloupci, kde by se vdova nebo sirotek vyskytli.
Pro použití balíčku postačí většině uživatelů LaTeXu uvést v preambuli dokumentu \usepackage{lua-widow-control}. Žádné další změny v dokumentu nejsou zapotřebí.
The lua-widow-control package, for plain LuaTeX/LuaLaTeX/ConTeXt/OpTeX, removes widows and orphans without any user intervention. Using the power of LuaTeX, it does so without stretching any vertical glue or shortening any pages or columns. Instead, lua-widow-control automatically lengthens a paragraph on a page or column where a widow or orphan would otherwise occur.
To use the lua-widow-control package, all that most LaTeX users need do is place \usepackage{lua-widow-control} in their preamble. No further changes are required.
