Until June 2004 the installation did consist in a zip file which
had to be extracted in the directory of your choice. But with version
0.97b IMaCh we are using a windows installer (Inno setup). Both
executables imach.exe and gnuplot.exe (the grapher
that we are using) have to be on the same directory.
In order to facilitate the use of IMaCh we associated the .imach
extension to two features: editing and running. Thus by right clicking
on a foo.imach file you can either 'edit'the file (default) with
the notepad editor or 'run' it with gnuplot (you need a recent version).
But we discovered that on some computers, people are not allowed
to modify the windows registry and need to have Administrator privileges.
Thus we built two windows installer: a standard setup which will install
the progam (usually in \Program Files\imach and will
modify the registry to associate .imach extension to notepad and imach, and a
second which will not alter the registry. With this second installer you
will be able to install the programs in your home directory and
run it by clicking on the imach.exe icon. But you won't be able
to use the facility of the right clicking.
Old Windows versions are accessible here.
It take a litle more time to get latest version of Gnuplot 4.0 for Mac
OS/X and to compile it on a MaC. The main problem resides in finding
the png library. Gif images are patented now and the replacement is
png, but the development of the png library is growing on its own and
you just have to find on Google where it is hosted now.
Gnuplot can be easily compiled on a MaC, but I don't know yet (July
2004) which is default screen terminal driver for gnuplot. For sure if
X11 is installed on your MaC (it is included on your installation CD
or you can download it from the WEB), the you can do set ter
X11 and plot sin(x) to get a nice sin curve on an X11
window of your Mac.
Let me add that for running IMaCh with all of its features, you don't
need X11; the gnuplot program included in the distribution needs only
to have the png terminal driver to output graphs and these graphs will
be viewed by your browser.
You need X11 only if you want to modify and test the gnuplot code output by
ImaCh, because it might be a more convenient way to view the graphs
directly on the screen than writing images on a file and viewing them
with a browser,
You can download a .pkg.paw file at imach097b.pkg.pax. Stuffit Expander will expand compressed imach097b.pkg directory. Just clicking on the directory will let you install ImaCh in a local directory of your own. Two sub-directories are created bin and html . In the bin subdirectory you will find two executables imach itself and gnuplot.
You need to click on imach and IMaCh will be launched in a terminal window, asking you to enter a parameter file. A parameter file is text file with an extension .imach (but you can use a .txt extension if you want. Among the parameters required, a data file name has to be entered. It can be a relative file name like ../../data/data1.txt. It might also work if you use the Windows backslash "\" syntax.
At the end of the run, and it order for the terminal window not to
disappear, the program prompt for a command like "e" for
edit or "q" for quit. The edit command might not work
on a MaC, or on Unix or even on recent Windows, because the program should know which
browser you are using and becauee the BROWSER environment
doesn't seem to be standard on a Mac and on some other OS too.
The consequence for you is just that you have to use your finder
or browser (there is no more difference now) and click on the
.html (or .htm) file created. The filename of this html
file is the same name as your parameter file, only the extension
.imach is changed to .html.
