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 pre-
       rex(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 dis-
       play 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 clip-
       board.  The cursor shape changes to a plus-sign to indicate successful capture of the coordinates.  Middle-clicking the mouse at  the  pre-
       rex(1)  command-line  will then paste those coordinates into a command being composed.  If the chart file is regenerated, the updated docu-
       ment 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.
