% \noindent
% This document shows the \LaTeX{} implementation of the
% package \textsf{documentation}.
% This package is intented for all software's writers who
% want to document their source codes by using the comments of the
% programming language.
% The source files are processed with \LaTeX{} in order to generate
% the documentation of them. 
% \end{abstract}

%
% \section{Introduction}
%
% On environments of software developtment is necessary to make
% the documentation of the source code according to its last modification.
% Sometimes, this is not easy, because of \emph{documentation} and
% \emph{source code} are written on different files.
%
% In order to avoid this situation, where a software maker 
% have to write two different files, \LaTeX{} gives the possibility
% to handle an unique file where source code and documentation
% are together. Through the \textsf{documentation} package a software
% maker can write the source code for his application, and inside of its comments,
% he can document it. It's only neccessary to put \LaTeX{} commands
% inside the comments of the source files.
% Source files are then proccesed by \LaTeX{} to get
% a beautiful document (PDF, DVI, PS, ...)
%
% The real advantage of this technique is that \LaTeX{}
% will be present to handle all the documentation.
% If a software maker wants to put a complex formula
% where he explains a difficult algorithm, then he will be able to do it
% in the usual way with \LaTeX{} commands. 
%
% \section{\textsf{Docstrip} modules}
%
% This package has been developed with the typical \LaTeX's
% documentation techniques. \textsf{Docstrip} has been used
% for the preparation of the source code of the package and its documentation.
%
% The following \textsf{docstrip} modules were implemented to generate
% the different files of this project.
%
% \vskip10pt
% \begin{tabular}{ll}
% \textbf{Option}&amp;\textbf{Result}\\
% \hline
% sty &amp; It generates the package's file |*.sty|\\
% drv &amp; It generates the \LaTeX{} documentation's master file |*.drv|\\
% \end{tabular} 
%
% \section{How to use}
%
% \DescribeMacro{\usepackage}
% This package is used in the usual way.
% You should use the |\usepackage| command in the preamble of your
% master's documentation file as follows
% \begin{verbatim}
% \usepackage[&lt;options&gt;]{documentation}
% \end{verbatim}
% The |&lt;options&gt;| are presented in the next section.
%
% \section{Options}
%
% \DescribeMacro{java}
% |java| option is used when JAVA language is used.
% In this programming language the comment's character is |//|
% when one-line's comments are needed. If multi-line's comments
% are needed then |/*| and |*/| are neccessary.
% Then, all the comments inside your JAVA code have to start with |//|,
% or to be enveloped with |/*| and |*/|.
%
% \DescribeMacro{c}
% |c| option is used when C language is used (or any of its variants like
% C++ or C\#). This is the default option.
% This programming language uses the same comment's character as
% JAVA language, then, this option is the same as |java|.
%
% \DescribeMacro{assembler}
% |assembler| option is used when assembler language is used,
% for example, when you are programming microcontrollers.
% In this programming language the comment's character is semicolon (|;|).
% All the comments (line-by-line) inside your assembler
% code have to start with |;|
%
% \section{How it works}
% 
% \begin{enumerate}
%	\item You should create your source code as usual in
%       C, C++, C\#, JAVA or assembler languages
%       (this step is done inside an IDE (Integrated Development
%       Environment\footnote{Typical IDEs are \emph{KDevelop} on Linux systems,
%                            \emph{Eclipse} on Windows systems or
%                            \emph{Microsoft Visual Studio} on Windows systems.
%                            Be careful when you're saving your source files on these IDEs.
%                            You should guarantee that they have the right coding
%                            as ASCII files})).
%       These programming languages use the following comment's characters
%
%       \begin{tabular}{lll}
%       Programming&amp;Comment's&amp;Name of comment's\\
%       language&amp;character&amp;character\\
%       \hline
%       C,C++,C\#,JAVA&amp;\texttt{//} or \texttt{/*} and \texttt{*/}&amp;Double slash or slash with asterisk\\
%       Assembler&amp;\texttt{;}&amp; Semicolon
%       \end{tabular}
%       
% \item Now, you can add the documentation of your source code
%       inside the comments.
%       You can use \LaTeX{} commands as usual.
%       You should think that you are writing a \LaTeX{}
%       document.
%       If you need to use the comment's character inside your source code,
%       then you will be able to use a \LaTeX{} command as
%       is shown in the following table
%
%       \begin{tabular}{lll}
%       Programming language&amp;Character&amp;\LaTeX{} command\\
%       \hline
%       C,C++,C\#,JAVA&amp;\texttt{/}&amp;|\/|\\
%       C,C++,C\#,JAVA&amp;\texttt{*}&amp;|\*|\\
%       Assembler&amp;\texttt{;}&amp; |\;|
%       \end{tabular}
%
% \item Any piece of source code have to be enveloped by
%       |\begin{sourcecode}| and |\end{sourcecode}|.
%       Just before of these two \LaTeX{} commands, you have to
%       put your comment's character \emph{without spaces}.
%       In C or JAVA, you have to use |//| before |\begin{sourcecode}| and |\end{sourcecode}|.
%       For example, if you are writing a C code,
%       then a piece of source code looks like
%       \begin{verbatim}
%       /*
%          This is helloworld.c
%       
%          Comments with \LaTeX{} commands...
%
%       */
%       //\begin{sourcecode}
%       #include&lt;stdio.h&gt; // Header file
%       //\end{sourcecode}
%       //
%       // More comments with \LaTeX{} commands... 
%       //
%       //\begin{sourcecode}
%       void main (void)
%       {
%          printf("Hello world!\n"); // "Hello world" message
%       }
%       //\end{sourcecode}
%       /*
%          More comments with \LaTeX{} commands...
%       */
%       \end{verbatim}
%       In C or JAVA you can use |//| or |/*| and |*/| to add comments,
%       but you have to use |//| before |\begin{sourcecode}| and
%       |\end{sourcecode}|.
%
% \item You can add a master's documentation file (|*.tex|) in your IDE.
%       In the preamble of this file you have to use
%       |\usepackage[&lt;options&gt;]{documentation}|.
%       Now, you can read all your source files of your project with the \LaTeX{} command
%       |\inputsourcecode{&lt;source file&gt;}| where |&lt;source file&gt;|
%       is the path of your source file with its
%       extension\footnote{Extension is needed because of some IDEs
%                          create different files with the same name and
%                          different extensions}.
%
%       For the previous example, this file looks like
%       \begin{verbatim}
%       %
%       % This is dochelloword.tex
%       %
%       \documentclass{article}
%       \usepackage[c]{documentation} % Needed
%       \begin{document}
%       \inputsourcecode{helloworld.c} % input your source code
%       \end{document}
%       \end{verbatim}
%       You can use any \LaTeX{} class (for example,
%       \textsf{article}, \textsf{book}, \textsf{report}, ...)
%       and any number of |\inputsourcecode| commands in order to read
%       any number of source files.
%
% \item Run \LaTeX{} as usual to get the documentation of your
%       source code. In the previous example, run
%       |dochelloword.tex| through \LaTeX.
%       |\inputsourcecode| will read your source files
%       and it will extract the documentation
%       from the comments.

% and to define the macros |\/| and |\*| to print
% |/| and |*| inside the text of the source files.
% 
%    \begin{macrocode}

% \begin{macro}{assembler}
%
% |assembler| option calls all the necessary code which is needed to make

% comment's characters |;| for all kind of comments.
%
% This option gives |true| value to |\ifDOC@assemblerlang| and
% |false| to others.
% Inside this option, |\DOC@changeccofcommentchar| and

%
%    \begin{macrocode}
\ExecuteOptions{c}\ProcessOptions\relax
%    \end{macrocode}
%
% \subsection{The source code}
%
% \begin{environment}{sourcecode}
%
% |\begin{sourcecode}| and |\end{sourcecode}| is the way
% as an user gives the source code for his application.
% All source code has to be enveloped with this environment
% in order to write it |verbatim|.
% The real difference with respect to |verbatim| is that
% |sourcecode| recognizes the comment's character of the
% programming language.
% This environment permits to write the comment's character
% inside without any special \LaTeX{} command (like |\/|, |\*| or |\;|).
% The only restriction is that you have to use the comment's
% character of your programming language just before
% |\begin{sourcecode}| and |\end{sourcecode}|
% \emph{without spaces} between them.
% |sourcecode| uses the internal macros
% |\@verbatim|, |\frenchspacing|, |\@vobeyspaces|, |\if@newlist|,
% |\leavevmode| and |\endtrivlist|.
% See |ltmiscen.dtx| for more details.
% 
%    \begin{macrocode}
\def\sourcecode{\DOC@changeccofcommentchar{12}%
                \@verbatim \frenchspacing\@vobeyspaces \DOC@sourcecode}%
\def\endsourcecode{\if@newlist \leavevmode\fi\endtrivlist}%
%    \end{macrocode}
% \end{environment}
%
% \begin{macro}{\DOC@sourcecode}
%
% |\DOC@sourcecode| recognizes the beginning and the end of
% the real source code by using the comment's character of your
% programming language. Then, this macro depends on the language.
% This macro begins changing some |\catcode|s of some characters
% because it's needed to say to \LaTeX{} where is
% the end of the source code. This is done inside a group
% because it's needed to keep local all changes.
%
%    \begin{macrocode}
\begingroup
  \catcode`|=0   \catcode`[= 1
  \catcode`]=2   \catcode`\{=12
  \catcode`\}=12 \catcode`\\=12
  |catcode`/=12  |catcode`;=12
%    \end{macrocode}
%
% Now, |\DOC@sourcecode| is defined according to the language.
% It's needed to say to \LaTeX{} that source code
% will finish with the comment's character of the
% programming language which is followed by |\end{sourcecode}|
% \emph{without spaces}.
% At the end, the group is closed.
% 
%    \begin{macrocode}
  |ifDOC@javalang
    |gdef|DOC@sourcecode#1//\end{sourcecode}[#1|end[sourcecode]]%
  |fi
  |ifDOC@Clang
    |gdef|DOC@sourcecode#1//\end{sourcecode}[#1|end[sourcecode]]%
  |fi
  |ifDOC@assemblerlang
    |gdef|DOC@sourcecode#1;\end{sourcecode}[#1|end[sourcecode]]%
  |fi
|endgroup
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\inputsourcecode}
%
% This is the way as an user |\input|s his source code.
% This command uses the classical |\input| \LaTeX{} command.
% It begins with the definition of |\DOC@path| as the path of the source file.
% |\DOC@path| is necessary because of UNIX systems use |/|
% as a delimiter on its directory tree (for example |/usr/share/local/|),
% and JAVA and C use the same character as comment's character.
% Everything is done inside a group.
%
%    \begin{macrocode}
\def\inputsourcecode#1{%
\begingroup
  \def\DOC@path{#1}%
%    \end{macrocode}
%
% Now, it's time to define the right command secuence if
% an user wants to print the comment's character inside
% the documentation, also,
% it's changed the |\catcode| of the comment's character which
% is treated as an space (catcode 10).
% 
%    \begin{macrocode}
  \DOC@definecsofcommentchar
  \DOC@changeccofcommentchar{10}%
%    \end{macrocode}
%
% At the end, the source file is red.
% Notice that |\inputsourcecode| keeps all changes local.
% Then, your source file doesn't affect any other part of
% your \LaTeX{} document. 
% 
%    \begin{macrocode}
