[Gnuplot-info] name of current script

[Robbie M. <ro...@ac...>]

Hello all

It would be rather useful if the current filename was
available from within a gnuplot script.

This suggestion was raised in 2008 and 2009
respectively:

  http://groups.google.com/group/comp.graphics.apps.gnuplot/browse_thread/thread/2b34fa67a0365173/8f8c63c891f59aeb?lnk=gst&q=%22current+filename%22#8f8c63c891f59aeb
  http://groups.google.com/group/comp.graphics.apps.gnuplot/browse_thread/thread/781545ccfbaada56/ebffa12161a37fe3?lnk=gst&q=%22get+filename%22#ebffa12161a37fe3

And, AFAIK, has not been resolved.

One approach might be:

assume the file 'myfile.gp' contains the lines:

    myfile = GPVAL_LOAD_FILE
    print "myfile = ", myfile

then entering the command:

    load "myfile.gp"

would display either of the following -- the first
being a simple echo and the second being the canonical
file path:

    myfile = myfile.gp
    myfile = /path/to/myfile.gp

On termination, GPVAL_LOAD_FILE would be unset.

Another approach (probably too late) would have been
to have the 'call' command assign the filename to $0
in line with most other shell positional variable
conventions.

If there is a work-around, that would be good to know.

best wishes
Robbie
