[texworks] Scripting read access

[Paul A Norman]

Thanks Stefan, I'll download your latest later and have a go.

I have been using the fileOpen functions to open all sub documents
when using a master document, there's been a script up on your script
Issues page for quite a few months now.

Its sort of useful especially when you need to search through all
documents - they all need to be open before the search starts. Or when
you  just want to position the cursor and open a sub document. (Select
between braces, get selected text, construct full path, open document)

If the user has  allowed scripts to read documents from disk - could
we make these script functions for actually opening Tw documents work
on the same User's check box preference selection? Perhaps
automatically allowing same target and script and sub directories as
for the readFile function itself?

There would be other times when it is very useful to be able to open
Tw document(s) from script for user editing.

Be sad to loose this functionality.

Or if we are pulling this out of Scripting - could we add a Tw File
menu item for Open File at cursor then? And another one for  open all
\include etc documents?

Or allow ALL things of this perceived security issue nature to be
doable if  "use script plugins" is ticked by the User, as after all
the script plugins automatically open the Pandora's box of security
issues wide open any way don't they?

Sort of a Master switch for all these things in a way isn't it?

It would seem counter intuitive that read or write scripts be turned
off, and script plugins be
turned on letting python and Lua then do things that QtScript can then
not do - seems confusing?
