Hello,
I think that the following attempt could be a quick and dirty solution.
The trick is to launch the command in the background and to redirect the
output in a text file, whose length is checked every dt seconds, which
allows to print the new content during the command execution. The
command stops when there is no change after 2 seconds (can be ajusted
below):
function cmd(cmdstr)
tmpfile=fullfile(TMPDIR,"out.txt");
host("start /B "+cmdstr +" > "+tmpfile)
s=0;
ns=0;
dt=1;
fd=mopen(tmpfile,"rb");
while %t
info=fileinfo(tmpfile)
if info(1) > s
ns = 0;
str = mgetstr(info(1)-s,fd)
mprintf("%s",str);
s=info(1)
elseif ns < 2
sleep(dt,"s")
ns = ns+1;
else
break
end
end
mclose(fd);
mdelete(tmpfile);
endfunction
--> cmd("ping www.google.fr")

Hi,
I need to run external (win32) terminal program inside scilab. I've tried
scilab functions like: host(), dos(), unix in different variants (unix_w, etc).
The problem is that all of them are not showing output of the program during
execution. Unfortunatelly I need to show info from win32 terminal program
during execution (showing it after execution is too late).
In Octave there is function system(), which shows outputs during program is
run. Both standard input and ouputs are passed to Octave Command Window, (i.e.
program is really waiting for pressing a key)
system("pause");
Press any key to continue . . .
Is there any possibility to achieve something similar in Scilab? At least if
interaction not possible, is it possible to show standard output before called
program is ended?
Kind regards,
Jan
