NAME

       vprerex   -   graphical   front-end   and   viewer  for  the  prerex(1)
       prerequisite-chart editor

SYNOPSIS

       vprerex basefile[.tex] [ chartfile[.tex] ]

       vprerex file.pdf

       vprerex

DESCRIPTION

       vprerex (visual prerex) is a GUI front-end and viewer for the prerex(1)
       interactive  editor of prerequisite-chart descriptions in the prerex(5)
       format.  The viewer may be  used  just  as  a  minimalistic  viewer  of
       arbitrary  PDF  files   but  supports editing of charts generated using
       prerex.sty(7) by allowing coordinates  of  course  boxes,  arrows,  and
       background  points  to  be  conveyed back to the prerex(1) command-line
       using the clipboard.

USAGE

       If vprerex is invoked on a PDF file, it simply displays that file.

       If the (first) argument does not have the .pdf suffix, it is assumed to
       be  the  base file for a LaTeX document containing a prerequisite-chart
       description in prerex(5) format, to be edited using  prerex(1).   If  a
       second  argument  is  supplied,  it  is  regarded  as  an included file
       containing the specific chart environment to be edited.

       If no arguments are supplied, a file-opening dialog allows the user the
       specify  the  prerex(1)  base  file to be edited (or the PDF file to be
       viewed); if a separate chartfile is needed, vprerex(1) must be  invoked
       wth two arguments on the command line.

       If  the  mouse  hovers  over a hyperlink in the PDF viewing window, the
       cursor shape will change to  a  pointing  finger  and  a  tooltip  will
       display  the URI.  If the PDF file displayed contains a chart generated
       using  prerex.sty(7)  and  the  background  coordinate  grid  has  been
       enabled,  left-clicking  the mouse on a course box, arrow mid-point, or
       background  point  will  load  the  relevant  coordinates  into  the  X
       clipboard.   The  cursor  shape  changes  to  a  plus-sign  to indicate
       successful capture of the coordinates.  Middle-clicking  the  mouse  at
       the  prerex(1)  command-line  will  then paste those coordinates into a
       command being composed.  If the chart file is regenerated, the  updated
       document will be re-loaded.

DEPENDENCIES

       vprerex  is  based on the Qt-4 library. It calls xterm(1) and prerex(1)
       for the editing window and uses poppler-qt4 for rendering PDF files.
