vprerex - graphical front-end and viewer for the prerex(1)
vprerex basefile[.tex] [ chartfile[.tex] ]
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.
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.
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.
