In +documents with figures, section headings, and equations, TeX can stretch the +vertical glue between items in order to prevent widows and orphans, but many +documents have no figures or headings. TeX can also shorten the page by +1 line, but this will give each page a different length which can make +a document look uneven. The typical solution is to strategically insert +@samp{\\looseness=1}, but this requires manual editing every time that the +document is edited. Lua-widow-control is essentially an automation of the +@code{\\looseness} method: it uses Lua callbacks to find stretchy paragraphs, +then it lengthens them to remove widows and orphans. Lua-widow-control is +compatible with all LuaTeX and LuaMetaTeX-based formats.") + ;; Use either license. + (license (list license:mpl2.0 license:cc-by-sa4.0)))) + (define-public texlive-babel-czech (package (name "texlive-babel-czech") |
