"WSH" is an acronym for "Windows Script Host" (or "Windows Scripting Host").
ActiveState references [L3 ]
"The Microsoft® Windows® Script Host (WSH) is a language-independent scripting host for 32-bit Microsoft Windows operating system platforms. Microsoft provides both Visual Basic® Script and JavaScript scripting engines with WSH. Microsoft anticipates that other software companies will provide ActiveX® scripting engines for other languages, such as Perl, TCL, REXX, and Python."
[... much else ...]
Visual Basic and ECMAScript [L6 ] are canonical WSH languages.
Among opportunities WSH affords: keystroke automation through usual Windows application menus.
See also Active Script, COM.
So, what are the Tcl scripting engines that connect WSH with Tcl?
escargo 6 Dec 2006 - Added [Category Testing] because automation of Windows events can be used for testing applications.
MG May 10 2011 - Has anyone ever used WSH from Tcl? I'd like to add the ability for people to write scripts/plugins for an app using WSH to make other languages available, but am not entirely sure where to start. Anyone have any examples or pointers they could share?
