The locations in gnuplot.ijs are individually coded for 3 OS configurations:
NB. set EXE as path to gnuplot binary NB. set JSDIR as path to gnuplot javascript scripts NB. hardwired OS assumptions that may need tweaking 3 : 0'' select. UNAME case. 'Win' do. EXE =: (jpath'~home/gnuplot/binary/gnuplot.exe')rplc'/';'\' JSDIR=: '~home/gnuplot/binary/share/gnuplot/4.4/js/' case. 'Linux' do. EXE =: '/usr/bin/gnuplot' JSDIR=: '~root/usr/share/gnuplot/gnuplot/4.4/js/' case. 'Darwin' do. EXE =: '/usr/local/bin/gnuplot' JSDIR=: '~root/usr/local/share/gnuplot/4.4/js/' case. do. assert. 0['unknown UNAME' end. To me, it is a matter of personal taste if one decides to modify their system to match what the script expects or to modify gnuplot.ijs to match what is currently on your system. There are several reasons I felt it is at least worth knowing about the path options in gnuplot.ijs. One reason is that the install directory for gnuplot can be a personal choice and does not seem to be as standardized as some packages. Another reason is that the path names include a version-specific element (/4.4/) that is likely to change depending on which version of gnuplot one decides to install. It is true that if you choose to update gnuplot.ijs, you will have to continue to manage that change when updates are made. On 2/17/2012 0:41, bill lam wrote: > I'm curious.
