% \begin{abstract}
%     The \textsf{bibleref-mouth} package is a \LaTeXe{} library that allows Bible references to be formatted in a consistent way.
%     It is similar to the \textsf{bibleref} package, except that the formatting macros are all purely expandable.
%     That is, they are all implemented in \TeX's mouth.
%     This means that they can be used in any expandable context, such as an argument to the \cs{url} command.
%     To write a reference, the document should use the command \verb|\bibleref|\marg{reference}.

% \section{Introduction}
% 
% Two excellent packages already exist for formatting Bible references:
% \href{http://ctan.org/pkg/bibleref}{\textsf{bibleref}} by Nicola Talbot and
% \href{http://ctan.org/pkg/bibleref-parse}{\textsf{bibleref-parse}} by Sebastian Kuhnert.
% This package draws heavily from the ideas in both of those.
% Those packages should meet any reasonable requirement for formatting a Bible reference, except for one:
% they do not work in an expandable context.
% This limitation occasionally turns into a problem, for example in these situations:
% \begin{itemize}
%     \item A Bible reference gets written within an \cs{edef} command
%     \item A Bible reference is part of a section heading
%     \item A Bible reference is used within a hypertext reference
% \end{itemize}
% The last situation may sound contrived, but it is reasonable that an informal document might wish to link to an online Bible, such as at \href{http://www.biblegateway.com/}{Bible Gateway}.
% This package supports such a linked reference.
% For example, a hypertext reference like the following can be produced by the command below:
% \setbiblestyle{biblegateway.com}%
% \bibleref{Gen 1:27}.
% 
% \begin{verbatim}
%\setbiblestyle{biblegateway.com}
%\bibleref{Gen 1:27}
% \end{verbatim}
% 
% \section{Usage}

% \DescribeMacro{\bibleref}
% For a reasonable default experience, it is sufficient to know only one command.
% The document should create a Bible reference by calling \verb|\bibleref|\marg{reference}.
% The entire reference should be passed as a single argument, even if it contains a range or list of verses.
% 
% Books can be spelled out or abbreviated.
% A list of supported abbreviations is given in Table~\ref{books}.
% Numbered books can be specified with Arabic or Roman numerals, with an optional space separating the number from the book.
% Abbreviations may have an optional trailing period.
% For example, it is equally acceptable to say
% \verb|IISamuel|,
% \verb|IISam.|,
% \verb|IISam|,
% \verb|2Samuel|,
% \verb|2Sam.|,
% \verb|2Sam|,
% \verb|II Samuel|,
% \verb|II Sam.|,
% \verb|II Sam|,
% \verb|2 Samuel|,
% \verb|2 Sam.|, or
% \verb|2 Sam|.
% Regardless of the format used in the \cs{bibleref} command, the reference will be formatted according to the active reference style.
% New custom books and abbreviations can be added, according to the pattern shown in section \ref{booknames}.

% References must contain a book name.
% They may optionally contain a chapter, and if they contain a chapter then they may optionally contain a verse.
% References may be created for a range from one passage to another.
% References may also be created for a list of passages.
% A space should separate the book name from the chapter number.
% (Spaces will actually be ignored by the parser, so it is also allowed to write the book and the chapter with no separation between them).
% The chapter and verse should be separated by a \texttt{:} character, and optionally spaces.
% The begin and end passages of a range should be separated by a \texttt{-} character, and optionally spaces.
% Two passages that are part of a list should be separated by a \texttt{;} character, and optionally spaces.
% If the passages in a range or a list are from the same book, then the book does not need to be specified for the second passage.
% Likewise, if the passages in a range or a list have the same book and chapter, then the chapter does not need to be specified for the second passage.
% However, if two passages are in a list and they have the same book and chapter, then they should be separated by a \texttt{,} character instead of a \texttt{;} character.
% This helps resolve the ambiguity around whether the number following the delimiter represents a chapter or a verse.
% 
% The following examples show most of the different reference types that are supported by the parser.
% \begin{itemize}
%     \item Single book: \verb|\bibleref{Genesis}|
%     \item Single chapter: \verb|\bibleref{Exodus 32}|
%     \item Single verse: \verb|\bibleref{Amos 3:7}|
%     \item Multiple books: \verb|\bibleref{Matt; Mark; Luke; John}|
%     \item Multiple chapters: \verb|\bibleref{Psalms 2; 16; 32; 69; 95; 110}|
%     \item Multiple verses within a chapter: \verb|\bibleref{Matthew 5:13,48}|
%     \item Multiple verses across chapters: \verb|\bibleref{John 7:17; 14:15; 17:3}|
%     \item Multiple different references: \verb|\bibleref{Isa. 9:6; Ezek. 37; Rev.}|
%     \item Range of books: \verb|\bibleref{Genesis - Deuteronomy}|
%     \item Range of chapters: \verb|\bibleref{Mal. 3-4}|
%     \item Range of verses: \verb|\bibleref{Proverbs 3:5-6}|
%     \item Range from a book to a chapter: \verb|\bibleref{1 Chronicles - 2 Chronicles 9}|
%     \item Range in a list within a chapter: \verb|\bibleref{James 1:5-6,17}|
%     \item Range in a list across chapters: \verb|\bibleref{Ezra 7-10; Neh 8}|

% \section{Implementation}
% 
% All the internal macros have a name beginning with \verb|brm@|, which stands for \textsf{bibleref-mouth}, so as to avoid polluting the global namespace.
% 
% It would have been nice if an expandable Bible reference could be created using the existing \textsf{bibleref} package, perhaps by adding \cs{protect} commands.
% Unfortunately, the reality of \TeX{} is more complicated than that.
% The entire package needed to be reimplemented using a functional programming paradigm.
% 
% There are some techniques that need to be used over and over to perform complicated computations in \TeX's mouth.
% All non-expandable primitives must be avoided.
% That means that assignments, (e.g.\ \cs{def}), cannot be used.
% Instead, recursion and currying and the command pattern are relied on extensively.
% In order to read this code, it doesn't hurt to be familiar with a language like \href{http://www.haskell.org/haskellwiki/Haskell}{Haskell}.
% 
% \subsection{Entry Points}
% 
% \begin{macro}{\setbiblestyle}
% The user can set which reference style is in effect with \verb|\setbiblestyle|\marg{stylename}.
% The available styles are defined in Table~\ref{styles}.
% Custom styles can also be added using the command \hyperlink{providebiblestyle}{\cs{providebiblestyle}}.
% This command just stores the style for later use by \cs{bibleref}.
% 
% Note that this command is itself \emph{not} expandable, so it must be called outside of any expandable context.
% If you need to switch between different styles within an expandable context, you should use the \hyperlink{brm@bibleref}{\cs{brm@bibleref}} command.
%    \begin{macrocode}
\newcommand*{\setbiblestyle}[1]{%
    \def\brm@currentstyle{#1}%
}
%    \end{macrocode}
% \end{macro}
% 
% The default style for documents that don't override it is the one that outputs the full name of the books.
%    \begin{macrocode}
\setbiblestyle{fullname}
%    \end{macrocode}
% 
% \begin{macro}{\bibleref}
% This is the main entry point to the library.
% The user can specify any Bible reference, including lists and ranges, as the argument to \verb|\bibleref|\marg{reference}.
% Detailed usage instructions are given in \autoref{bibleref}.
% This command just retrieves the current style and delegates to \cs{brm@bibleref}.
%    \begin{macrocode}
\newcommand*{\bibleref}[1]{%
    \brm@bibleref{\brm@currentstyle}{#1}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@bibleref}
% \hypertarget{brm@bibleref}{}
% The \verb|\brm@bibleref|\marg{stylename}\marg{reference} command checks that the style exists, and then outputs a consistently formatted reference.
% It gets a list of ranges from \cs{brm@parseall}.
% Then it starts reading the list by creating a cons handler from the partially applied function \cs{brm@formatall}.
% The first argument passed to \cs{brm@formatall} is a style, which is itself a function with the signature \callback\-\marg{beginpassage}\-\marg{endpassage}\-\marg{list}.
% No nil handler needs to be provided, because an empty list would be an error, and would not need to be formatted anyway.
%    \begin{macrocode}
\newcommand*{\brm@bibleref}[2]{%
    \brm@ifnameexists{\brm@style{#1}}{%
        \brm@readlist{\brm@parseall{#2}}{%
            \brm@formatall{\csname\brm@style{#1}\endcsname}%
        }{%
        }%
    }{%
        \brm@error{Unrecognized style: #1}%
    }%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@formatall}
% The formatting of a Bible reference starts with \verb|\brm@formatall|\marg{style}\marg{range}\marg{list}.
% This command gets called from \cs{brm@readlist}, so the last two arguments are the head and tail of a list.
% This command unpacks a range into a begin passage and an end passage, which are passed to the helper \cs{brm@applystyle}.
%    \begin{macrocode}
\newcommand*{\brm@formatall}[3]{%
    \brm@unpackrange{#2}{\brm@applystyle{#1}{#3}}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@applystyle}
% The command \verb|\brm@applystyle|\marg{style}\marg{list}\marg{beginpassage}\-\marg{endpassage} rearranges the arguments into the order that is recognized by the style function.
% It forwards the begin passage and end passage, and it also allows continued extraction from the list by passing the partially applied function \cs{brm@nextrange}.
% The style can finish applying \cs{brm@nextrange} by providing a style delegate and a nil handler.
% The style delegate that gets provided to format subsequent ranges need not be the same style command that is being applied to format the first range.
%    \begin{macrocode}
\newcommand*{\brm@applystyle}[4]{%
    #1{#3}{#4}{\brm@nextrange{#2}}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@nextrange}
% The command \verb|brm@nextrange|\marg{list}\marg{style}\marg{nilhandler} allows styles to read the next range off of a list of references.
% Since the list will already have been given by \cs{brm@applystyle}, the style only needs to provide the style delegate and nil handler.
%    \begin{macrocode}
\newcommand*{\brm@nextrange}[3]{%
    \brm@readlist{#1}{%
        \brm@formatall{#2}%
    }{%
        #3%
    }%
}
%    \end{macrocode}
% \end{macro}
% 
% \subsection{Data Structures}
% 
% A list can be represented as a recursive data structure, as in other functional languages.
% But data structures themselves are difficult to construct in \TeX.
% Some hints can be found in the \href{http://ctan.org/pkg/lazylist}{\textsf{lazylist}} package.
% A data structure can be represented as a macro that accepts a callback.
% When the callback is invoked, all the data structure's fields are passed to it.
% The simplest form of callback is one that returns one field and ignores all the others.
% If that sounded complicated, then the following sample code might help or it might make the confusion worse.
% 
% \begin{macro}{\brm@packpassage}
% One important data structure is the passage.
% It is created by \verb|\brm@packpassage|\marg{book}\marg{chapter}\marg{verse}.
% You may notice that the command signature advertises 4 parameters, but the user only calls it with 3 arguments.
% That's because the fourth argument is a callback that will be supplied later, when it's time to extract the data.
% For now, all this command does with its arguments is passes them to the callback.
%    \begin{macrocode}
\newcommand*{\brm@packpassage}[4]{%
    #4{#1}{#2}{#3}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\thebook}
% The first such callback is \verb|\brm@choosebook|\marg{book}\marg{chapter}\marg{verse}.
% It gets passed the three fields from the passage.
% It returns the book, and ignores the chapter and verse.
% There is also a public command, \verb|\thebook|\marg{passage}, which wraps the operation in a command that has a more familiar syntax.
% These commands work in concert to support use cases like the following:
% \begin{verbatim}
%% Store a passage in \mypassage.
%\def\mypassage{\brm@packpassage{Jeremiah}{16}{16}}
%% Later, extract the book from \mypassage into \mybook.
%\def\mybook{\thebook{\mypassage}}
% \end{verbatim}
%    \begin{macrocode}
\newcommand*{\thebook}[1]{%
    #1{\brm@choosebook}%
}
\newcommand*{\brm@choosebook}[3]{%
    #1%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\thechapter}
% The \verb|\thechapter|\marg{passage} command is a similar command for extracting a chapter.
% The callback is \cs{brm@choosechapter}.
% It ignores the first and third fields, and returns the second field, which is the chapter.
%    \begin{macrocode}
\newcommand*{\thechapter}[1]{%
    #1{\brm@choosechapter}%
}
\newcommand*{\brm@choosechapter}[3]{%
    #2%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\theverse}
% Likewise, \verb|\theverse|\marg{passage} extracts a verse.
% The callback \cs{brm@chooseverse} returns the third field and ignores the others.
%    \begin{macrocode}
\newcommand*{\theverse}[1]{%
    #1{\brm@chooseverse}%
}
\newcommand*{\brm@chooseverse}[3]{%
    #3%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@packrange}
% Another data structure is the range.
% It has a begin passage and and end passage.
% A range is created by calling \verb|\brm@packrange|\-\marg{beginpassage}\-\marg{endpassage}.
%    \begin{macrocode}
\newcommand*{\brm@packrange}[3]{%
    #3{#1}{#2}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@unpackrange}
% The corresponding command to extract the fields is \verb|\brm@unpackrange|\marg{range}\marg{callback}.
% This doesn't follow exactly the same pattern as the passage helpers.
% Instead of having separate commands to extract the two fields, there is a single function that extracts both fields at the same time.
% Clients should pass in a callback with the signature \callback\-\marg{beginpassage}\-\marg{endpassage}.
%    \begin{macrocode}
\newcommand*{\brm@unpackrange}[2]{%
    #1{#2}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@packseparators}
% Another data structure is for separators.
% This structure stores the delimiter characters that will be output between books and chapters, and between chapters and verses, in Bible references.
%    \begin{macrocode}
\newcommand*{\brm@packseparators}[3]{%
    #3{#1}{#2}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\bookchapterseparator}
% To extract the first field of the separators structure, use \verb|\bookchapterseparator|\marg{separators}.
% Instead of defining a custom callback, it was sufficient to use the existing \cs{@firstoftwo} command, which already does exactly what we want.
% It returns the first field and ignores the second field.
%    \begin{macrocode}
\newcommand*{\bookchapterseparator}[1]{%
    #1{\@firstoftwo}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\chapterverseseparator}
% To extract the second field of the separators structure, use \verb|\chapterverseseparator|\marg{separators}.
%    \begin{macrocode}
\newcommand*{\chapterverseseparator}[1]{%
    #1{\@secondoftwo}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@nillist}
% Now we arrive at the package's only recursive data structure, which is for storing lists.
% The definition mirrors lists in the lamba calculus.
% This mechanism was suggested by the \textsf{lazylist} package.
% Each list node is a data structure that is either a nil or a node.
% A nil means an empty list.
% It is represented as a function that ignores its first argument and expands its second argument.
%    \begin{macrocode}
\newcommand*{\brm@nillist}{%
    \@secondoftwo%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@conslist}
% Every non-empty list node contains fields for the list head and the list tail.
% The list head is the current first item in the list.
% The list tail is its own list, and it contains all the items except the head.
% If the head is the only element in the list, then the tail is nil.
% A list node is represented as a function that calls its first argument and ignores its second argument.
% The first argument must be a callback with the signature \callback\marg{head}\marg{tail}.
%    \begin{macrocode}
\newcommand*{\brm@conslist}[2]{%
    \brm@conslist@choose{#1}{#2}%
}
\newcommand*{\brm@conslist@choose}[4]{%
    #3{#1}{#2}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@readlist}
% Reading a list is done with the command \verb|\brm@readlist|\marg{list}\marg{conshandler}\marg{nilhandler}.
% If the list is empty, then the \meta{nilhandler} will be called without any arguments.
% If the list is non-empty, then the \meta{conshandler} will be called.
% It should have the signature \callback\marg{head}\marg{tail}.
%    \begin{macrocode}
\newcommand*{\brm@readlist}[3]{%
    #1{#2}{#3}%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@recordrange}
% A list of references is kept using the list structure.
% Each element is one of the range structures.
% The list is constructed with \verb|\brm@recordrange|\-\marg{beginbook}\marg{beginchapter}\marg{beginverse}\-\marg{endbook}\marg{endchapter}\marg{endverse}\-\marg{tail}.
% The tail passed to this command should be a list that contains all subsequent ranges, or nil if there are no more ranges.
%    \begin{macrocode}
\newcommand*{\brm@recordrange}[7]{%
    \brm@conslist{%
        \brm@packrange{%
        	\brm@packpassage{#1}{#2}{#3}%
        }{%
        	\brm@packpassage{#4}{#5}{#6}%
        }%
    }{%
        #7%
    }%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@recordpassage}
% A single passage can be added to the list as a range that has a regular begin passage and empty fields for the end passage.
% It is done with the command \verb|\brm@recordpassage|\marg{book}\marg{chapter}\marg{verse}\marg{tail}.
%    \begin{macrocode}
\newcommand*{\brm@recordpassage}[4]{%
    \brm@recordrange{#1}{#2}{#3}{}{}{}{#4}%
}
%    \end{macrocode}
% \end{macro}
% 
% \subsection{Parsing}
% 
% \subsubsection{Reference Parsing}
% 
% \begin{macro}{\brm@parseall}
% Parsing starts with the command \verb|\brm@parseall|\marg{remainingtext}.
% It checks whether the reference begins with a valid book.
% It finds the longest string at the beginning of the input that is a valid book, consuming both letters and numbers that are part of the book name.
% If it finds a match, then parsing continues with the \cs{brm@checkchapter} command.
% 
% Throughout this section, \texttt{1 Cor 15:20-22,40-42;16} will be used as a sample reference.
% The reference will be shown with a vertical bar, or cursor, at the point where the parsing has advanced.
% When this command is called, the cursor will be at: \texttt{\cursor1 Cor 15:20-1 Cor 15:22,40-42;16}.

}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@checkchapter}
% After the book has been parsed, \verb|\brm@checkchapter|\marg{book}\marg{remainingtext} is called.
% 
% A valid reference may contain only a book name, in which case there is no remaining text.
% 
% The remaining text could also contain a chapter, which this command will check for.
% The last alternative is that there is a delimiter separating this reference from more references.
% 
% When this command is called, the cursor will be at: \texttt{1 Cor \cursor15:20-1 Cor 15:22,40-42;16}.

% 
% \begin{macro}{\brm@parsebook}
% The \verb|\brm@parsebook|\marg{text}\marg{successhandler}\marg{failurehandler} command parses a book name.
% A book is known to exist if the definition \cs{brm@bookalias@\meta{book}} exists.
% This command will find the longest string of the source that is a valid book name.
% In other words, it will check to see whether the whole string is a valid book name, and then it will try to match the whole string minus the last character, and so on recursively.
% Eventually it will either find a valid book or it will exhaust every possibility and fail.
% If it finds a valid book then it will call the success handler, which is expected to have the signature \callback\-\marg{book}\-\marg{remainingtext}.
% If it doesn't find a valid book it will call the failure handler with no arguments.
% 
% This command depends on \cs{brm@headstr}, which consumes all spaces in its input.
% That means that spaces in the text will be ignored.
% For example, if the text contains \texttt{Song of Songs}, then it will only match a book alias \texttt{SongofSongs}.
% 
% The real work is done by the \cs{brm@parsebook@accumulate} helper, so this method just delegates to it.
% It makes sure the text is fully-expanded before beginning.
% It passes an empty string as the accumulated text, because at the start of the process nothing has accumulated yet.

% \begin{macro}{\brm@parsebook@accumulate}
% The recursive workhorse for parsing books is \verb|\brm@parsebook@accumulate|\-\marg{remainingtext}\marg{accumulatedtext}\-\marg{successhandler}\marg{unwindhandler}.
% The unwind handler is called with no arguments if the parsing fails.
% 
% This command uses \cs{brm@headstr} to pull the first token off of the remaining text string.
% It then adds that character to the end of the accumulated text.
% The new string is a potential book alias that has not been tested yet.
% So in that way, character by character, it is able to try every possible book name.
% 
% A complication is that it encounters each possible book name starting with the shortest, but it actually wants to give precedence to the longest book names.
% So when it finds a possible book name, it doesn't actually test it yet to see whether it is valid.
% Instead it simply makes a recursive call to try the next longer possible book name.
% It passes in an unwind handler, which will only be called if all the longer book names fail.
% It is only within the unwind handler that tests whether the string is valid.
% If the string is valid, then the success handler is called, and parsing stops.
% If the string is invalid, then the caller's unwind handler will be invoked.
% In that way it will continue to unwind all the recursive calls, testing each successively shorter string at each level.
% 
% This code uses the \cs{romannumeral} trick to make sure that the text strings are always fully expanded, because otherwise the \cs{brm@tailstr} command would have to be re-evaluated many times on the same input.
% With the full expansions in place, this algorithm completes in linear time.
% Without them, it would be polynomial time.

% \label{booknames}
%
% All the same books and book names that are supported by the \textsf{bibleref} package are supported here too.
% Each book is given a full name, an abbreviation, and an alternative abbrevation.
% Users can define more names or abbreviations if they wish.
% Examples of how to extend the collection of supported books are shown in the \textsf{bibleref-lds} package.
% 
% \begin{macro}{\brm@foreachbook@full}
% There are several different use cases for full book names.
% There are also several varieties of each full name.
% For example, the book number could be formatted with either Arabic or Roman numerals.
% To provide the greatest amount of flexibility, callback gets invoked for each formatted full name.
% This command has the signature \verb|\brm@foreachbook@full|\-\marg{callback}\-\marg{space}\-\marg{bookof}\-\marg{gospelof}\-\marg{epistleto}\marg{epistletothe}\marg{epistleof}\-\marg{booknumberstyle}\marg{epistlenumberstyle}.
% The callback argument is expected to have the signature \callback\-\marg{book}\marg{bookname}.
% The callback can do whatever it wants with the names, such as creating a permanant book alias.
% The two number style arguments are expected to be functions with the signature \callback\marg{number}.

% \subsubsection{Default Styles}
% \label{defaultstyles}
% 
% All the styles that are supported by the \textsf{bibleref} package are supported here too.
% Each one is made to delegate to the \cs{standardbiblestyle} helper.
% The parameters to that helper determine the punctuation and spacing that will be used in the formatted output.
% The helper's signature is \verb|\standardbiblestyle|\-\marg{bookstyle}\-\marg{bkchsep}\marg{chvsep}\-\marg{bksep}\marg{chsep}\marg{vsep}\-\marg{rangesep}\-\marg{chapterstyle}\marg{versestyle}\-\marg{beginpassage}\-\marg{endpassage}\-\marg{list}.
% The \cs{providebiblestyle} command creates an environment in which three parameters are defined, for the begin passage, the end passage, and the passage list.
% 
% New styles can be defined by creating new definitions like the ones here, except with different punctuation or spacing.
% Examples of how to define custom styles are found in the \textsf{bibleref-lds} package.

% \subsection{Text Style}
% 
% The style that outputs a textual description of the reference is more complicated than the others.
% It needs to be defined here in its own section.
% 
% \emph{This style depends on commands that are not expandable, so this style is unique in that it may not be used in an expandable context.}
% It would be possible to implement this style in an expandable manner, by providing replacements for the \textsf{fmtcount} package's \cs{numberstringnum} and \cs{Ordinalstringnum} commands.
% The effort required would be large, however, and this style is less likely to be needed in an expandable context anyway.
% 
% \begin{macro}{\brm@number@stomach@text}
% This special number format spells out the number using its English word.
% \emph{This command relies on \cs{numberstringnum}, which is not expandable.}
%    \begin{macrocode}
\newcommand*{\brm@number@stomach@text}[1]{\numberstringnum{#1}}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@number@stomach@ordspace}
% This special number format spells out the number using its English ordinal word.
% This is useful for book numbers, such as \texttt{First}.
% \emph{This command relies on \cs{Ordinalstringnum}, which is not expandable.}
%    \begin{macrocode}
\newcommand*{\brm@number@stomach@ordspace}[1]{\Ordinalstringnum{#1}~}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@number@stomach@chapter}
% This special number format prefixes the text with the label ``chapter.''
% It delegates to \cs{brm@number@stomach@text}.
% \emph{This command relies on \cs{numberstringnum}, which is not expandable.}
%    \begin{macrocode}
\newcommand*{\brm@number@stomach@chapter}[1]{chapter\ %
    \brm@number@stomach@text{#1}}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@number@stomach@verse}
% This special number format prefixes the text with the label ``verse.''
% It delegates to \cs{brm@number@stomach@text}.
% \emph{This command relies on \cs{numberstringnum}, which is not expandable.}
%    \begin{macrocode}
\newcommand*{\brm@number@stomach@verse}[1]{verse\ %
    \brm@number@stomach@text{#1}}
%    \end{macrocode}
% \end{macro}
% 
% The style of book names spells out all the titles and uses English text instead of numerals.
%    \begin{macrocode}
\brm@foreachbook@full{\providebiblebook{text}}%
    {\ }%
    {Book of }{Gospel according to St.~}%
    {Epistle to }{Epistle to the }{Epistle of }%
    {\brm@number@stomach@ordspace}%
    {\brm@number@stomach@ordspace}
%    \end{macrocode}
% 
% The style of references spells out all the conjunctions and numbers.
%    \begin{macrocode}
\providebiblestyle{text}{\standardbiblestyle{text}%
    {,\ }{\ }{,\ and\ }{,\ and\ }{,\ and\ }{\ to\ }%
    {\brm@number@stomach@chapter}{\brm@number@stomach@verse}%
    {#1}{#2}{#3}}
%    \end{macrocode}
% 
% \subsection{Bible Gateway Style}
% 
% Since the parsing commands are all expandable, it is possible to parse a reference within a \cs{url} command.
% Then, the formatted output can be made to look like a valid URL rather than a human-readable style.
% So creating a link to a Bible reference uses all the same implementation machinery as the non-linked styles.
% The URL could be made to point to a variety of targets.
% This section illustrates how to create a link to \href{http://www.biblegateway.com/}{Bible Gateway}.
% The user may add other styles to link to any other sites.
% 
% First, the book names are defined.
% Bible Gateway uses the full names of the books and Arabic numerals.
% The ASCII version of the space character must be used, because a non-breaking space would not URL-encode to a space character correctly.
%    \begin{macrocode}
\brm@foreachbook@full{\providebiblebook{biblegateway.com}}%
    {\ }{}{}{}{}{}%
    {\brm@number@arabicspaceascii}{\brm@number@arabicspaceascii}
%    \end{macrocode}
% 
% \begin{macro}{\providebiblegatewayurl}
% The Bible Gateway site publishes \href{http://www.biblegateway.com/versions/}{many versions of the Bible}, (e.g. \href{http://www.biblegateway.com/versions/New-International-Version-NIV-Bible/}{NIV}).
% A user that wishes to have their preferred version embedded in the URL should use \verb|\providebiblegatewayurl|\-\marg{urlstylename}\-\marg{version}.
%    \begin{macrocode}
\newcommand*{\providebiblegatewayurl}[2]{%
    \providebiblestyle{#1}{%
        \brm@biblegatewayurl@style{#2}{##1}{##2}{##3}%
    }%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@biblegatewayurl@style}
% The Bible Gateway URL is constructed by the style \verb|\brm@biblegatewayurl@style|\-\marg{version}\-\marg{beginpassage}\-\marg{endpassage}\-\marg{list}.
% Note that ampersands in the address are represented as \verb|\&| instead of \verb|&|, so it will still work in contexts where the ampersand is an active character.
% It uses the standard Bible style by calling \cs{brm@standard@filtered}, and it is allowed to specify a filter.
% The filter is \cs{brm@biblegatewayurl@filter}, which alters the standard format to meet the Bible Gateway requirements.
%    \begin{macrocode}
\newcommand*{\brm@biblegatewayurl@style}[4]{%
    http://www.biblegateway.com/passage/?search=%
    \brm@standard@filtered%
        {\brm@packseparators{ }{:}}%
        {\brm@packpassage{; }{; }{,}}%
        {\brm@packpassage{-}{-}{-}}%
        {\brm@packpassage%
            {\thebookname{biblegateway.com}}%
            {\brm@formatchapter{\brm@number@arabic}}%
            {\brm@formatverse{\brm@number@arabic}}}%
        {\brm@biblegatewayurl@filter{-}}%
        {#2}{#3}{#4}%
    \&version=#1%
}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\brm@biblegatewayurl@filter}
% A filter for standard formats is \verb|\brm@biblegatewayurl@filter|\-\marg{rangesep}\-\marg{lastpassage}\marg{passage}\-\marg{infixseparators}\-\marg{prefixes}\-\marg{formatters}\-\marg{delegate}.
% It makes sure that each new passage in a list contains the book name, not just the chapter or verse.
% This is because Bible Gateway sometimes behaves unexpectedly if a number is specified without a book name, and it is ambiguous whether the number represents a chapter or a verse.
% Ranges, (as opposed to lists), behave normally and are not altered.
%    \begin{macrocode}
\newcommand*{\brm@biblegatewayurl@filter}[7]{%
    \brm@ifsamestr{\theverse{#5}}{#1}{%
        % Show ranges like normal.
        #7{#2}{#3}{#4}{#5}{#6}%
    }{%
        % List the book explicitly for each list element.
        #7{\brm@packpassage{}{}{}}{#3}{#4}{#5}{#6}%
    }%
}
%    \end{macrocode}
% \end{macro}
% 
% A URL style that creates links for Bible Gateway references is defined.
% Users may define other styles for different versions of the Bible at Bible Gateway.
%    \begin{macrocode}
\providebiblegatewayurl{biblegateway.com-url}{NIV}
%    \end{macrocode}
% 
% \begin{macro}{\providebiblegatewaystyle}
% Different users might wish to define links for a variety of styles.
% For example, a user might wish to have either full text or abbreviated text being linked.
% To provide this flexibility, there is the \verb|\providebiblegatewaystyle|\-\marg{stylename}\-\marg{urlstylename}\marg{textstylename} command.
% The user first gives the name for this new style, and then gives the name of the existing style that will be used to format the link, and then finally the name of the existing style that will be used to format the linked text.
%    \begin{macrocode}
\newcommand*{\providebiblegatewaystyle}[3]{%
    \providebiblestyle{#1}{%
        \href{%
            \brm@delegatestyle{#2}{##1}{##2}{##3}%
        }{%

        }%
    }%
}
%    \end{macrocode}
% \end{macro}
% 
% A style is defined that uses a link style for the Bible Gatway NIV version and full names for the linked text.
% Users may define other styles for different link formats or different linked text formats.
