+% \maketitle
+%
+% \begin{abstract}
+% This is a modified version of the file \texttt{hyphen.cfg} distributed with
+% the \textsf{babel} package, with a supporting Lua module, aimed at adapting
+% \textsf{babel}'s hyphenation patterns loading mechanism to Lua\TeX's dynamic
+% pattern loading capabilities. It makes use of a \texttt{language.dat.lua}
+% file (whose format is described below) that should be present in the
+% distribution, in addition to the regular \texttt{language.dat} file.
+%
+% There is a version of \texttt{etex.src} modified for the same reasons using
+% similar code, which also makes use of the \texttt{luatex-hyphen.lua} and
+% \texttt{language.dat.lua} files described here.
+% \end{abstract}
+%
+% \section{Documentation}
+%
+% Hyphenation patterns should be loaded at runtime with Lua\TeX: if they appear
+% in the format, they will be rehashed when the format is loaded anyway, which
+% makes the format quite long to load (many seconds even on modern machines)
+% and provides for bad user experience. Hence, it is desirable to load as few
+% patterns as possible in the format, and load on-demand the needed patterns
+% at runtime.
+%
+% This package provides a modified version of hyphen.cfg adapted to Lua\TeX,
+% as well as a supporting Lua module. Since a lot of things, especially the
+% catcodes, are not as predictable at runtime than at format creation time, we
+% don't \verb+\input+ the usual pattern files, but rather load the patterns
+% using the Lua interface, using a special plain text version of the pattern
+% files if available.
+%
+% The existence and file name of such a version cannot be guessed, so we need
+% a specific database: the file \texttt{language.dat.lua}. This file should be
+% loadable by Lua and return a table whose keys are the canonical language
+% names as found in \texttt{language.dat}, and the values are Lua tables
+% consisting of:
+% \begin{enumerate}
+% \item A fixed part with two fields:
+% \begin{quote}
+% \verb+loader = <string> name of the TeX loader+\\
+% \verb+synonyms = { <string> alternative name, ...}+
+% \end{quote}
+% Those field's values must be the same as in \texttt{language.dat}. The
+% \verb+loader+ field is currently unused.
+% \item A variable part consisting of either:
+% \begin{itemize}
+% \item For most languages:
+% \begin{quote}
+% \verb+patterns = <string> filename for patterns+\\
+% \verb+hyphenation = <string> filename for exceptions+\\
+% \verb+lefthyphenmin = <number> value for \letfhyphenmin+\\
+% \verb+righthyphenmin = <number> value for \letfhyphenmin+
+% \end{quote}
+% The files given by \verb+patterns+ (resp. \verb+hypenation+) must be
+% plain text files encoded in utf8, with only patterns (resp.
+% exceptions) and not even comments: their content will be used
+% directly without being parsed by \TeX. If one of these keys is
+% missing or is the empty string, it is ignored and no patterns (resp.
+% exceptions) are loaded for this language. The values of
+% \texttt{*hyphenmin} are currently unused.
+% \item Special case are supported by a field \verb+special+. Currently,
+% the following kind of values are recognized:
+% \begin{description}
+% \item[\texttt{'null'}] for languages with no hyphenation patterns
+% nor exceptions. (Note that this is equivalent to both
+% \verb+hyphenation+ and \verb+patterns+ being \verb+nil+ or
+% \verb+''+, but produces a more explicit message in the log.)
+% \item[\texttt{'disabled:<reason>'}] allows to disable specific
+% languages: when the user tries to load this language, an error
+% will be issued, with the \verb+<reason>+.
+% \item[\texttt{'language0'}] only \texttt{english} should use this
+% type of special, to indicate it is normally dumped in the format
+% as \verb+\language0+ (see below).
+% \end{description}
+% Special languages may have \texttt{*hyphenmin} information when it
+% makes sense (mostly \verb+\language0+).
+% \end{itemize}
+% \end{enumerate}
+% Languages that are mentioned in \texttt{language.dat} but not in
+% \texttt{language.dat.lua} will be loaded in the format. So, if the
+% \texttt{language.dat.lua} file is missing or incomplete, languages will just
+% go back to the ``old'' behaviour, resulting in longer startup time, which
+% seems less bad than complete breakage.
+%
+% For backward compatibility, Knuth's original patterns for US English are
+% always loaded in the format, as \verb+\language0+.\footnote{It is assumed
+% to be the first entry in \texttt{language.dat}.}
+%
+% The modified version of \texttt{hyphen.cfg} provided here checks for the
+% engine, and should continue to work with any engine without any modified
+% behaviour. However, it is recommended to install it in such a way that the
+% original \verb+hyphen.cfg+ from \textsf{babel} is found first by any engine
+% other than Lua\TeX.

+% \section{Implementation}
+%
+% \subsection{luatex-hyphen.lua}
+%
+% \begin{macrocode}
+%<*lua>
+% \end{macrocode}
+%
+% Start a Lua module, importing only the necessary functions as locals.
+%
+% \begin{macrocode}
+local error, dofile, pairs, ipairs = error, dofile, pairs, ipairs
+local io, texio, lang, kpse = io, texio, lang, kpse
+module('luatexhyphen')
+% \end{macrocode}
+%
+% Two functions for error and information reporting.
+%
+% \begin{macrocode}
+local function wlog(msg, ...)
+ texio.write_nl('log', 'luatex-hyphen: '..msg:format(...))
+end
+local function err(msg, ...)
+ error('luatex-hyphen: '..msg:format(...), 2)
+end
+% \end{macrocode}
+%
+% Load the \texttt{language.dat.lua} file with the Lua version of the
+% language database.
+%
+% \begin{macrocode}
+local dbname = "language.dat.lua"
+local language_dat
+local dbfile = kpse.find_file(dbname)
+if not dbfile then
+ err("file not found: "..dbname)
+else
+ language_dat = dofile(dbfile)
+end
+% \end{macrocode}
+%
+% Look up a language in the database, and return the associated
+% information, as well as the canonical name of the language.
+%
+% \begin{macrocode}
+function lookupname(name)
+ if language_dat[name] then
+ return language_dat[name], name
+ else
+ for canon, data in pairs(language_dat) do
+ for _,syn in ipairs(data.synonyms) do
+ if syn == name then
+ return data, canon
+ end
+ end
+ end
+ end
+end
+% \end{macrocode}
+%
+% Set hyphenation patterns and exceptions for a language given by its name
+% (in the database) and number (value of \verb+\language+). Doesn't return
+% anything, but will call \verb+error()+ if things go wrong.
+%
+% \begin{macrocode}
+function loadlanguage(lname, id)
+ local msg = "loading%s patterns and exceptions for: %s (\\language%d)"
+% \end{macrocode}
+%
+% Lookup the language in the database.
+%
+% \begin{macrocode}
+ local ldata, cname = lookupname(lname)
+ if not ldata then
+ err("no entry in %s for this language: %s", dbname, lname)
+ end
+% \end{macrocode}
+%
+% Handle special languages.
+%
+% \begin{macrocode}
+ if ldata.special then
+ if ldata.special == 'null' then
+ wlog(msg, ' (null)', cname, id)
+ return
+ elseif ldata.special:find('^disabled:') then
+ err("language disabled by %s: %s (%s)", dbname, cname,
+ ldata.special:gsub('^disabled:', ''))
+ elseif ldata.special == 'language0' then
+ err("\\language0 should be dumped in the format")
+ else
+ err("bad entry in %s for language %s")
+ end
+ end
+% \end{macrocode}
+%
+% The generic case: load hyphenation patterns and exceptions from files
+% given by the language code.
+%
+% \begin{macrocode}
+ wlog(msg, '', cname, id)
+ for _, item in ipairs{'hyphenation', 'patterns'} do
+ local file = ldata[item]
+ if file ~= nil and file ~= '' then
+ local file = kpse.find_file(file) or err("file not found: %s", file)
+ local fh = io.open(file, 'r')
+ local data = fh:read('*a') or err("file not readable: %s", f)
+ fh:close()
+ lang[item](lang.new(id), data)
+ end
+ end
