[Gnuplot-py-users] Test.py suite errors

[Trevor L. <law...@gm...>]

Hello,

I recently obtained Gnuplot.py and it appears to be importable.  However,
when I ran the test.py script, I got
the following error message (I believe from gnuplot):

"
gnuplot> set terminal postscript eps enhanced
gnuplot> set output "gp_test.ps"
gnuplot> plot cos(0.5*x*x) title "cos(0.5*x^2)" with linespoints 2 2
gnuplot> set terminal x11
gnuplot> set output
Testing hardcopy options: mode="default"
Press return to show results...

gnuplot> set terminal postscript default enhanced
gnuplot> set output "gp_test.ps"
gnuplot> plot cos(0.5*x*x) title "cos(0.5*x^2)" with linespoints 2 2
gnuplot> set terminal x11
gnuplot> set output
Testing hardcopy options: enhanced=1
Press return to show results...
         line 714: undefined variable: default
"

Otherwise the tests seemed to work fine (although some did not produce the
visual changes I expected,
I do not know enough about gnuplot to know if there are any issues).  The
command in test.py that results
in the error appears to be line 223.

I would just like to make sure this is not a major issue that would indicate
that gnuplot.py is not functioning correctly
on my machine.

Sorry for the two mailing list posts.  I don't anticipate having to be any
more of a bother.

Mailing lists are for questions, don't worry.

Nothing should fail in the tests, if they do, something is wrong.
Personally I'm running from the SVN version, are you? I did not fully 
understand
this release mail as nothing is on sourceforge.
Anyway, checkout from SVN: http://sourceforge.net/svn/?group_id=17434 
and follow
install instructions. Then run the test.py

[Gnuplot-py-users] Fwd: Test.py suite errors

[Trevor L. <law...@gm...>]

Regarding error described below in reply history.  I followed the svn
instructions (and did essentially what I believe I did before).  The same
error occurred.  So something does appear to fail in the tests (as described
below).  If someone with experience working with the source could let me
know whether or not this test error is serious, I would appreciate it very
much.

Thank you for your time,

Trevor Law

It appears that the error message is emitted by gnuplot when Gnuplot.py
sends it the command "set terminal postscript default enhanced".
Probably the "default" option has been removed.

According to my version of gnuplot's "help set terminal postscript",
"default" is a valid option.  Obviously it must have been valid when the
test suite was written.  But presumably this option has been removed
from gnuplot without the documentation having been updated.

I wouldn't worry about it.  If the rest of the test suite runs OK, then
you shouldn't have any problems (as long as you don't use the "default"
option for hard copies!)

Patches to the test suite and/or Gnuplot.hardcopy() method (which
actually requires changes in termdefs.py) would be welcome.

I dug in a bit and it appears that the 4.1+ behavior is this:

set term post
    sets the term to postscript with whatever values are current

set term post def
    sets the terminal to postscript with default values or
    resets post term values to defaults

set term post enh
    sets the terminal to enhanced postscript

set term post noenh
    sets the terminal to noenhanced postscript

set term post def enh
    throws an 'extraneous argument' warning and does nothing

enhanced/noehanced is not changed by def
