Hello Thomas
Many many thanks for this. I will try to test your
patch this weekend and report back.
with best wishes, Robbie

Hello all
First up, thanks Vinod for your suggestion of a bash
wrapper script.
Please note the following corrections: exho is echo,
the OUT assignment (righthand-side) should be in
backticks (`) not single-quotes ('), --persist should
be -persist.
I reworked the original script and tested it on Linux
plus Gnuplot 4.2 patchlevel 6:
--- src begin / bash --------
#! /bin/bash
# usage message (optional)
case "$1" in
--help|--hel|--he|--h|-help|-hel|-he|-h|"-?")
SCRIPT=$(basename "$0")
echo " usage: $SCRIPT <gnuplot-cmds> create LOADFILE string
and load gnuplot-cmds file"
echo " $SCRIPT --help show this message and exit"
exit 0
;;
"")
SCRIPT=$(basename "$0")
echo "$SCRIPT: gnuplot file name required (try --help for usage)"
exit 2
esac
# active code
ARG1=$(basename "$1") # adapt these next two lines to
your needs
ARG1="$PWD/$ARG1"
echo "LOADFILE = \"$ARG1\"; load '$1'" | gnuplot -persist
----src end -----------------
And tested it with the following gnuplot code:
--- src begin / gnuplot -----
set title "source : " . LOADFILE # 'LOADFILE' is set by invoking
script
plot sin(x)
--- src end -----------------
best wishes
Robbie

Hello all, hi Thomas
I can confirm the patch from Thomas Sefzick (see below)
works for real files but not for 'stdin'. The patch
allows the name of the current script to be recovered
from within that script. I suggest the patch gets
developed a little and transferred to the gnuplot mainline.
Can someone therefore cross-post this message to the
dev list please? TIA.
The patch was tested on Ubuntu 10.04 (64-bit) / Linux
2.6.32-32-generic / gcc 4.4.3 / Intel Core i5-520M.
Here are the build calls:
$ ./configure --without-lua # 11 seconds
$ make # 35 seconds
The test script:
$ cat gpval-load-file.gp
show version
print GPVAL_LOAD_FILE
Some trials:
$ src/gnuplot gpval-load-file.gp

After examining 'misc.c', I should imagine the fix to
this problem would be straightforward.

if there is no load file, then GPVAL_LOAD_FILE is undefined,
i.e. not existing, and this can be tested using the 'exists()'
function:
if (exists("GPVAL_LOAD_FILE")) print GPVAL_LOAD_FILE

Hello Thomas, hello all
I guess I was being a bit cryptic about my suggestion
regarding input that was either redirected from 'stdin'
or piped from another command. In this case,
GPVAL_LOAD_FILE should be assigned "-". Which suggests
that perhaps GPVAL_FILE would be a better name for this
variable, because 'stdin' is a type of file in the sense it
gets file descriptor 0.
Can I recommend this concept gets developed and added
to the mainline codebase. Hint!
thanks
Robbie

Hello Thomas, all
To follow up on my early posting, here is a list of
"GPVAL_[A-Za-z0-9_]*" strings in 4.4.3 codebase. Some
may be commented out or in conditional code -- I did
not check:
GPVAL_
GPVAL_COMPILE_OPTIONS
GPVAL_DATA
GPVAL_DATA_
GPVAL_ERRMSG
GPVAL_ERRNO
GPVAL_LAST_PLOT
GPVAL_LOAD_FILE
GPVAL_MULTIPLOT
GPVAL_NAME_WINDOWID
GPVAL_NaN
GPVAL_OUTPUT
GPVAL_PATCHLEVEL
GPVAL_PI
GPVAL_PLOT
GPVAL_PWD
GPVAL_SPLOT
GPVAL_TERM
GPVAL_TERMINALS
GPVAL_TERMOPTIONS
GPVAL_TERM_
GPVAL_TERM_WINDOWID
GPVAL_TERM_XMAX
GPVAL_TERM_XMIN
GPVAL_TERM_YMAX
GPVAL_TERM_YMIN
GPVAL_VERSION
GPVAL_VIEW_
GPVAL_VIEW_MAP
GPVAL_VIEW_ROT_X
GPVAL_VIEW_ROT_Z
GPVAL_VIEW_SCALE
GPVAL_VIEW_ZSCALE
GPVAL_X2_MAX
GPVAL_X2_MIN
GPVAL_X_MAX
GPVAL_X_MIN
GPVAL_Y2_MAX
GPVAL_Y2_MIN
GPVAL_Y_MAX
GPVAL_Y_MIN
GPVAL_pi
And here is a list of what is available after simply
opening gnuplot:
$ gnuplot
gnuplot> show variables all
<edited and sorted>
GPVAL_COMPILE_OPTIONS = <long list deleted>
GPVAL_ERRMSG = ""
GPVAL_ERRNO = 0
GPVAL_MULTIPLOT = 0
GPVAL_NaN = NaN
GPVAL_OUTPUT = ""
GPVAL_PATCHLEVEL = "3"
GPVAL_PLOT = 0
GPVAL_PWD = "/home/robbie/synk/temp"
GPVAL_SPLOT = 0
GPVAL_TERM = "wxt"
GPVAL_TERMINALS = <long list deleted>
GPVAL_TERMOPTIONS = "0"
GPVAL_VERSION = 4.4
It would seem the suggestion of GPVAL_FILE would sit
quite well with GPVAL_PWD.
best wishes
Robbie
