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.
