isMacintosh boolean in a macro?

[Bill Mohler]

I've just come across the mismatch in path punctuation in macros
between Mac and Windows:  "/" vs "\\" to demarcate directory levels
when I record a save command in the recorder.

I found an isMacintosh boolean in some of the ij. code.  But I didn't
find an obvious command in the macro language command list that would
let my macro detect the platform it's running on.

Is there an easy way to detect the OS from in a macro, so I can
substitute in the correct punctuation?  I assume that ImageJ is aware
of its environment, but how do I ask it?

Thanks,
Bill

Yes, search for "os" in this page:
http://rsbweb.nih.gov/ij/developer/macro/functions.html

you will find this:

getInfo(key)
Returns the Java property associated with the specified key
(e.g., "java.version", "os.name", "user.home", "user.dir", etc.). Returns an
empty string if there is no value associated with the key. See also:
getList("java.properties"). Requires 1.38m.

which is what you want, I think.
I hope it helps
Cheers

G.

Thanks.
I  had  tried  this, and was lost in all the hits on macrOS.

Use the File.separator() function to get the file path separator,  
which is "/" on Macs and Linux and "\\" on Windows. Note that the  
getDirectory() macro function returns a file path that ends with a  
path separator.

Use

    if (getInfo("os.name")=="Mac OS X")
       print("This is a Mac")

or

    if (call("ij.IJ.isMacintosh")=="true")
       print("This is a Mac")

to test to see if you are running on a Macintosh.
