#287 make script file name available to script code

[Daniel Dan K.]

Hello all,

I heavily rely on scripts to display data.

My setup is that I have "01.txt" as data file and "01 plot.gp" as script file, etc.

My question: is there a command / way to refer to the name of the script inside the script (the equivalent of bash's $0)? My goal is to derive the name of the data file from the name of the script file in order to plot it.

Thanks.
Daniel

Have you tried looking at variable ARG0?

test.gp:

show variables ARG

print "Script name is " . ARG0

This script produces output like

    Variables beginning with ARG:
    ARGC = 0
    ARG0 = "test.gp"
    ARGV = <0 element array>
    ARG1 = ""
    ARG2 = ""
    ARG3 = ""
    ARG4 = ""
    ARG5 = ""
    ARG6 = ""
    ARG7 = ""
    ARG8 = ""
    ARG9 = ""

Script name is test.gp

My environment is gnuplot 5.4.8 installed via Macports on MacOS.

Thanks a lot. That's helpful.

If anybody is interested: this is my way to extract the script name from ARG0:

start=1; while(1) { pos=strstrt(ARG0[start:], '\') ; if(pos==0) {break;}; start=start+pos; }; scriptname=ARG0[start:]

print "script name='".scriptname."'"

works on Windows.
