%D When loading hyphenation patterns, \TEX\ assign a number to
%D each loaded table, starting with~0. Switching to a specific
%D table is done by assigning the relevant number to the
%D predefined \COUNTER\ \type{\language}. Unfortunately the
%D name of this command suits very well the name of the
%D language switching command we are to define, so let's save
%D this primitive under another name:

\let\normallanguage = \language

%D We keep track of the last loaded patterns by means of a
%D pseudo \COUNTER. This just one of those situations in which
%D we don't want to spent a real one.

\newcounter\loadedlanguage

%D \macros
%D   {currentlanguage}
%D
%D Instead of numbers,we are going to use symbolic names for
%D the languages. The current langage is saved in the macro
%D \type{\currentlanguage}.

\let\currentlanguage = \empty

%D \macros
%D   {installlanguage}
%D
%D Hyphenation patterns can only be loaded when the format file
%D is prepared. The next macro takes care of this loading. A
%D language is specified with
%D
%D \showsetup{\y!installlanguage}
%D
%D When \type{\c!status} equals \type{\v!start}, both patterns
%D and additional hyphenation specifications are loaded. These
%D files are seached for on the system path and are to be
%D named:
%D
%D \starttypen
%D \f!languageprefix-identifier.\f!patternsextension
%D \f!languageprefix-identifier.\f!hyhensextension
%D \stoptypen
%D
%D The \type{\c!spatiering} specifies how the spaces after
%D punctuation has to be handled. English is by tradition more
%D tolerant to inter||sentence spacing than other languages.
%D
%D This macro also defines \type{\identifier} as a shortcut
%D switch to the language. Furthermore the command defined as
%D being language specific, are executed. With
%D \type{\c!default} we can default to another language
%D (patterns) at format generation time. This default language
%D is overruled when the appropriate patterns are loaded (some
%D implementations support run time addition of patterns to a
%D preloaded format).

% ^^ \language[#1] gave unwanted side effect of loading language specifics 

\def\installlanguage%
  {\dodoubleargument\doinstalllanguage}

%D When the second argument is a language identifier, a 
%D synonym is created. This feature is present because we 
%D used dutch mnemonics in the dutch version, but nowadays 
%D conform a standard.  

%D \macros 
%D   {setuplanguage}
%D
%D Quick and dirty, but useful: 
%D
%D \showsetup{\y!setuplanguage}

\def\setuplanguage[#1]%
  {\dodoubleargument\getparameters[\??la#1]}

%D The values \type {\c!leftsentence} and \type
%D {\c!rightsentence} can be (and are) used to implement
%D automatic subsentence boundary glyphs, like in {\fr
%D |<|french guillemots|>|} or {\de |<|german guillemots|>|} or
%D {\nl |<|dutch dashes|>|} like situations. Furthermore \type
%D {\c!leftquotation} and \type {\c!leftquote} come into view
%D \citaat {when we quote} or \citeer {quote} something.

%D \macros
%D  {currentdatespecification}
%D
%D Just to make things easy we can ask for the current date
%D specification by saying:

\def\currentdatespecification%
  {\getvalue{\??la\currentlanguage\c!datum}}

%D This command is not meant for users.

%D Carefull reading of these macros shows that it's legal to
%D say
%D
%D \starttypen
%D \installlanguage [du] [de]
%D \stoptypen

%D \macros
%D   {language,mainlanguage}
%D
%D Switching to another language (actually another hyphenation
%D pattern) is done with:
%D
%D \starttypen
%D \language[identifier]
%D \stoptypen
%D
%D or with \type{\identifier}. Just to be compatible with
%D \PLAIN\ \TEX, we still support the original meaning, so
%D
%D \starttypen
%D \language=1
%D \stoptypen
%D
%D is a valid operation, where the relation between number
%D and language depends on the order in installing languages. 
%D
%D \showsetup{\y!language}
%D \showsetup{\y!mainlanguage}
%D
%D Both commands take a predefined language identifier as
%D argument. We can use \type{\mainlanguage[identifier]} for
%D setting the (indeed) main language. This is the language
%D used for translating labels like {\em figure} and {\em
%D table}. The main language defaults to the current language.
%D
%D We take care of local as well as standardized language
%D switching (fr and fa, de and du, but nl and nl).

%D   {startlanguagespecifics,enablelanguagespecifics}
%D
%D Each language has its own typographic pecularities. Some of
%D those can be influenced by parameters, others are handled by
%D the interface, but as soon as specific commands come into
%D view we need another mechanism. In the macro that activates
%D a language, we call \type{\enablelanguagespecifics}. This
%D macro in return calls for the setup of language specific
%D macros. Such specifics are defined as:
%D
%D \starttypen
%D \startlanguagespecifics[de]
%D   \installcompoundcharacter "a {\"a}
%D   \installcompoundcharacter "e {\"e}
%D   \installcompoundcharacter "s {\SS}
%D \stoplanguagespecifics
%D \stoptypen
%D
%D Instead of \type{[du]} we can pass a comma separated
%D list, like \type{[du,nl]}. Next calls to this macro add the
%D specifics to the current list.
%D
%D Before we actually read the specifics, we first take some
%D precautions that will prevent spurious spaces to creep into
%D the list.

\def\startlanguagespecifics%                % we use double to 
  {\bgroup
   \catcode`\^^I=\@@ignore
   \catcode`\^^M=\@@ignore
   \catcode`\^^L=\@@ignore
   \dodoubleempty\dostartlanguagespecifics} % get rid of spaces

%D The main macro looks quite complicated but actually does
%D nothing special. By embedding \type{\do} we can easily
%D append to the lists and also execute them at will. Just to
%D be sure, we check on spurious spaces.
