+# Luavlna, version v0.1b, 2018-05-31
+
+# Introduction
+
+`Luavlna` is a small package for plain LuaTeX and LuaLaTeX. In some languages,
+like Czech or Polish, there should be no single letter words at the
+line end, according to the typographical norms. There exists some
+external commands (like `vlna`) or packages (`encxvlna` for encTeX,
+`xevlna` for XeTeX, `impnattypo` for LuaLaTeX).
+
+Other feature of this package is including of non-breakable space after initials,
+like in personal names, after or before academic degrees
+and between numbers and units (SI and others).
+
+The code is modified version of Patrick Gundlach’s answer on
+TeX.sx[^1]. The difference is that it is possible to specify which
+single letters should be taken into account for different
+languages.
+The support for degrees and units was added as well.
+
+# Usage
+
+The usage is simple:
+
+ \input ucode
+ \uselanguage{czech}
+ %% in the case of luacsplain, use instead:
+ %% \chyph
+ %% but language code for Czech is different than in LaTeX or normal
+ %% LuaTeX, so you will need to set single letters with somethinh like:
+ %% \singlechars{5}{AIiVvOoUuSsZzKk}
+ \input luavlna
+ \preventsingledebugon
+ \input luaotfload.sty
+ \font\hello={name:Linux Libertine O:+rlig;+clig;+liga;+tlig} at 12pt
+ \hsize=3in
+ \hello
+ Příliš žluťoučký kůň úpěl ďábelské ódy.
+ Text s krátkými souhláskami a samohláskami i dalšími jevy
+ z nabídky možností (v textu možnými).
+
+ I začátek odstavce je třeba řešit, i když výskyt zalomení není pravděpodobný.
+
+ Co třeba í znaky š diakritikou?
+
+ Různé možnosti [v závorkách <i jiných znacích
+
+ Podpora iniciál a titulů: M. J. Hegel, Ing. Běháková, Ph.D., Ž. Zíbrt.
+
+ Podpora jednotek: 100,5 MN\cdot{}s, 100.5 kJ, 200 µA, $-1$ dag, 12 MiB, 1 m$^3$/s.
+
+ \preventsingledebugoff
+ \bye
+
+
+It is also possible to use the package with lua, just use
+
+ \usepackage{luavlna}
+
+in the preamble.
+
+# Commands
+
+ \singlechars{language name}{letters}
+
+Enable this feature for certain letters in given language.
+
+Default values:
+
+ %% only Czech and Slovak are supported out of the box
+ \singlechars{czech}{AIiVvOoUuSsZzKk}
+ \singlechars{slovak}{AIiVvOoUuSsZzKk}
+
+ \compoundinitials{language name}{compounds}
+
+Declare compound letters for given language. Second argument should be comma
+separated list of compound letters, in exact form in which they can appear.
+
+Default values:
+
+ \compoundinitials{czech}{Ch}
+
+##Turning off language switching
+
+By default, language of the nodes is taken into account. If you want to use
+settings for one language for a whole document, you can use following command:
+
+ \preventsinglelang{language name}
+
+##Turning off processing
+
+If you want to stop processing of the spaces in the document you can use
+command
+
+ \preventsingleoff
+
+To resume processing, use
+
+ \preventsingleon
+
+## Debugging commands
+
+ \preventsingledebugon
+ \preventsingledebugoff
+
+Insert debugging marks on/off. Default off.

+\section{Lua module \texttt{luavlna-langno.lua}}
+
+When we process glyph nodes with Lua\TeX\ callbacks, there are \verb|lang|
+fields available. These are numerical codes of languages, but no information
+about language names easily accesible from Lua side is available.\footnote{%
+ Language names are stored in \TeX macros like \verb|\string\l@langname|, but
+ different formats use different naming of these macros}
+These numbers are format dependent, majority of formats like
+Lua\LaTeX use \verb|language.dat| file provided by \verb|babel|
+for assign numbers to languages, but for example \verb|csplain|
+use its own system.
+
+To allow easy setting of language dependent parameters, \verb|langno| module
+was created. It's purpose is to translate language code to language name and
+the other way. Lua\LaTeX, Lua\TeX\ and CSplain formats are supported at the moment.
+
+\subsection{Recognized languages}
+\subsubsection{Lua\TeX\ and Lua\LaTeX}
+
+File \verb|language.dat| is processed to load language names, aliases and assigned numbers. These language names are the same as supported by \verb|babel| package.
+
+\begin{quotation}
+ \small\noindent
+\begin{luacode*}
+ langno = require "luavlna-langno"
+ function print_format_lang(fmt)
+ local luatex = langno.load_languages(fmt)
+ local t = {}
+ for k, v in pairs(luatex.names) do
+ t[#t+1]=k
+ end
+ table.sort(t)
+ tex.print(table.concat(t,", "))
+ end
+ print_format_lang("luatex")
+\end{luacode*}
+\end{quotation}
+
+\subsubsection{CSplain}
+
+Different method is used. File \verb|hyphen.lan| is included in CSplain, where
+language numbers are assigned to ISO-639-1 or ISO-639-2 language codes.
+These language codes were then normalized to names used vy \verb|babel|, or
+standard English language names.
+
