ES does not recognize an environment variable

[rombanks]

Hello fellows,

On my Win 7 system, I've redefined the HOME environment variable as C:\Users\bnks (by default, it's C:\Documents and Settings\Users\bnks).

I'd like to save an FM file to C:\Users\bnks\Checkout\Test\, so in my extendscript, I've defined the following variable:

var docLib = "~\\Checkout\\Test\\";

where the tilde (~) should be parsed by extendscript as the HOME environment variable (according to Chapter 3, “File System Access” in the JavaScript Tools Guide).

Unfortunately, the tilde is ignored when I try to save the file:

...

var dname = docLib + rName + ".fm";

doc.Save(dname, saveParams, returnParams);

...

Any idea why this happens?

Thank you!!!

The tilde doesn't work for me either (FM11), but you can get the value of an environment variables with $.getenv():

var docLib = $.getenv("HOME") + "\\Checkout\\Test\\";

Hi JoH,

Thank you for your response and for the suggestion! It does work. I wonder why tilde doesn't.

BTW, why is the $ sign used before the getenv(" ") function?

Thanks!

Hi rombanks

BTW, why is the $ sign used before the getenv(" ") function?

have a look at:

Chapter 8, page 216, “Dollar ($) object” in the JavaScript Tools Guide
