[jawsscripts] Re: Jamal's script library

Hi Jamal

Thank you for putting these in the script library. I did not look carefully
enough so did not find your delete file function, so wrote my own instead,
together with my own get list of drives function.  but that's OK.  I did not
get to the sound devices one so I will try out the others.  Again, thanks
for a great collection of functions, particularly the string analysis ones
which are extremely useful!

I appreciate the feedback, which is gratifying and encouraging!  I assume
that Brian found a solution to deleting a file via a JAWS script (e.g.,
with the FileDelete function in the Homer script library).  I like a
programming challenge <grin>, so have tried to add functions to the
library that he found missing.  I was able to add to Homer.jss the
function ShellGetDrives, which uses the Windows script host, and the
function BooShellGetSoundDevices, which uses IronCOM:  a COM server that
provides access to the .NET Framework -- available at
http://www.EmpowermentZone.com/comsetup.exe

Below is the ShellGetDrives function, followed by the Boo script that is
called by the BooShellGetSoundDevices function.  As usual, HomerKit is
available as an executable installer at
http://www.EmpowermentZone.com/kitsetup.exe

or as a zip archive (for manual or selective installation) at
the same URL except for a .zip extension,
http://www.EmpowermentZone.com/kitsetup.zip

In my opinion, Boo is currently the best scripting language for the .NET
Framework.  IronCOM installs the latest distribution of this open source
language, including documentation.  In addition, the EdSharp editor,
available at
http://www.EmpowermentZone.com/edsetup.exe

now includes a configuration for the Boo compiler (chosen with the Pick
Compiler command, Control+Shift+F5).  This configuration assumes that
IronCOM has been installed at the default location,
C:\Program Files\IronCOM

Also, a new EdSharp command called Go to Environment, Control+Shift+G, is
set by default to open the Boo interpreter (similar to the Python
interactive environment), where one can test Boo expressions and scripts.

Let me know if you have further questions.

Cheers,
Jamal
