% \begin{abstract}
% This package allows to include information about a git-repository into a document. 
% This information can be included like the watermark in this document or by the use of variables. 
% \end{abstract}
%
% \section{Introduction}
% If your LaTeX-document is version-controlled with git, you might encounter situations, where you want to include some information of your git-repository into your LaTeX-document - e.g. to keep track on who gave you feedback on which version of your document. 
% 
% \section{Options}
% \DescribeMacro{gitdir}
% custom git dir (can be relative), (default is ".git/", meaning your LaTeX document is in the top level of your repo)
% 
% \DescribeMacro{watermark}
% watermark with branch + hash on top of page (default: don't use watermark)
% 
% \DescribeMacro{nowatermark}
% same as watermark=false
% 
% \DescribeMacro{novariables}
% disable creation of variables (default: false, hence variables are created)
% 
% 
% \section{Variables}
% Apart from the option to add a watermark at the top of the page that mentions the current commit hash and branch-name, the package also provides variables with the same information for individual use. 
% These variables are:
% \DescribeMacro{\gitdir}
% The directory of the git repository. 
% 
% \DescribeMacro{\gitcommit}
% The hash of the most recent commit of the current branch. 
% 
% \DescribeMacro{\gitbranch}
% The name of the current branch. 
% 
%
% \StopEventually{\PrintChanges}
%
% \section{Implementation}
% 
% \subsection{Required Packages}
% The package relies on five other packages. Three are listed here, the other two are only required if a watermark is created.
%    \begin{macrocode}
\RequirePackage{kvoptions}
\RequirePackage{catchfile}
\RequirePackage{xstring}
%    \end{macrocode}
% 
% \subsection{Options}
% The options are defined.
%    \begin{macrocode}
\DeclareStringOption[.git/]{gitdir}                    % custom git dir (can be relative)
\DeclareBoolOption[false]{watermark}                   % watermark with branch + hash on top of page
\DeclareComplementaryOption{nowatermark}{watermark}
\DeclareBoolOption[false]{novariables}                 % disable creation of variables
\ProcessKeyvalOptions*
%    \end{macrocode}
% 
% 
% \subsection{Getting Git Information}
% Git information is read directly from the files within the specified git-directory.
% 
% \subsubsection{Branch Name} 
% Branch is read from HEAD. 
%    \begin{macrocode}
\def\gitstatus@headpath{\gitstatus@gitdir HEAD}
\IfFileExists{\gitstatus@headpath}{
    \CatchFileDef{\gitstatus@headfull}{\gitstatus@headpath}{}
    \StrGobbleRight{\gitstatus@headfull}{1}[\gitstatus@head]
    \StrBehind[2]{\gitstatus@head}{/}[\gitstatus@branch]
}{
    \def\gitstatus@branch{NOT AVAILABLE}
    \PackageWarning{gitstatus}{Can't find HEAD (maybe check specified gitdir).}
}
%    \end{macrocode}
%
% \subsubsection{Commit Hash}
% Commit-Hash is read from refs/heads/&lt;branch-name&gt;. 
%    \begin{macrocode}
\def\gitstatus@branchpath{\gitstatus@gitdir refs/heads/\gitstatus@branch}
\IfFileExists{\gitstatus@branchpath}{
    \CatchFileDef{\gitstatus@commit}{\gitstatus@branchpath}{}
}{
    \def\gitstatus@commit{NOT AVAILABLE}
    \PackageWarning{gitstatus}{Can't read commit hash (maybe check specified gitdir).}
}
%    \end{macrocode}
% 
% \subsection{Defining Local Variables}
% Make directory, branch and hash available outside of package
%    \begin{macrocode}
\ifgitstatus@novariables
\else
    \def\gitdir{\gitstatus@gitdir}
    \def\gitbranch{\gitstatus@branch}
    \def\gitcommit{\gitstatus@commit}
\fi
%    \end{macrocode}
% 
% \subsection{Creating Watermark}
% Include git information as watermark.
%    \begin{macrocode}
\ifgitstatus@watermark
    \RequirePackage{xcolor}
    \RequirePackage[printwatermark]{xwatermark}
    \newwatermark
        [allpages,color=black!20,angle=0,scale=0.5,align=left,xpos=-2cm,ypos=13cm]
        {On branch: \texttt{\gitstatus@branch}\\ Commit: \texttt{\gitstatus@commit}}
\fi
%    \end{macrocode}
% 
% \PrintIndex
% 
% \Finale
