%% USAGE: 
%
% \vpagelineref{<label>} expands to 
%
% a) \ref{<label>} 
%    -- if on same page as \linelabel{<label>}
% 
% b) \LineWithPage{<label>} -- otherwise. 
% 
% \LineWithPage{<label>} expands -- by default -- to 
% 
%   \pageref{<label>}.\ref{<label>}
% 
% This can be customized by editing 
% 
%   \renewcommand*{\LineWithPage}[1]{\pageref{#1}.\ref{#1}} 
% 
% in your document preamble, after vplref.sty has been loaded 
% (which may have happened through lineno.sty with option 
% `addpageno'). 

%% IMPLEMENTATION: 

\NeedsTeXFormat{LaTeX2e}[1994/12/01] %% \Declare...* 
\ProvidesPackage{vplref}[\filedate\space v\fileversion] 

\AtBeginDocument{\RequirePackage{lineno,varioref}} 

%% Anderer Ansatz: GPNo (\FirstOnPage) 

\DeclareRobustCommand*\vpagelineref[1]{{% 
%   \def\reftextcurrent{\lineref{#1}}%% First vpageref arg. 
  \let\reftextfaraway\LineWithPage 
  \def\reftextafter{\reftextfaraway{#1}}% 
  \let\reftextbefore\reftextafter 
  \let\reftextfaceafter\reftextafter 
  \let\reftextfacebefore\reftextafter 
%% <- Looks somewhat stupid, but varioref.sty has its merits 
%%    as compared with the mechanism in ednotes.sty. 
  \vpageref[\ref{#1}][]{#1}%% The robust alternative. 
%% Here and with \LineWithPage, \lineref seems more appropriate 
%% than \ref, but it produces errors when labels have not been 
%% defined. This seems to be an incompatibility with lineno.sty. 
}} 

%% Customizable format for different page: 
\newcommand*\LineWithPage[1]{\pageref{#1}.\ref{#1}}
