Re: [Gnuplot-info] epslatex outputs into different directories sometimes

[Thomas S. <t.s...@fz...>]

i wouldn't call it a bug, it's a feature...
it's documented ('help set terminal pslatex': the section about 'auxfile')

what happens is:
'set output "foo.tex"' opens the file 'foo.tex' in the current directory
and creates a filehandle which is used for writing into it.

you change the directory ('cd ..')

'plot' produces the output file, which is 'subdir/foo.tex', because
the filehandle was already existing before you changed the directory.

'foo.tex' (which in reality is 'subdir/foo.tex') is then closed and the
output file for writing the eps code is opened using
'EPSLATEX_reopen_output()'
in 'pslatex.trm' simply by cutting off the extension from 'foo.tex',
so the output file is now 'foo.eps'.
and it is opened in the actual directory because gnuplot doesn't
care for directories (why should it?) as long as you don't specify
one (like in your 2nd example).

so, 'cd' doesn't have an effect on an already specified output file,
but it does have an effect an the auxiliary output file which is
produced after the main output file is written.

you shouldn't change directories between 'set output' and 'plot'
commands.
