[texworks] Sweave with Texworks - Update

If you have a relatively recent development scriptable version of the
Tw editor ...

For various system needs QtScript in TexWorks can run a system call.

In the Tw Editor, goto Menu/  Edit/Preferences/ Scripts  tab,  and
tick everything in the  panel. Ok out

To see all available TwScript commands available to lua, python and
QtScript, run this as a TeXWorks .js script

// TeXworksScript
// Title: Debug
// Description: Starts the Debugger
// Author: Jonathan Kew
// Version: 0.1
// Date: 2010-03-18
// Script-Type: standalone


Then look for TW object and under it "app" and "target"

(Also you can search for Script in the Tw issues list. Ther are
already some worked examples there of some things.)

So QtScript can also obtain the curent filename of the edit document.

So if you want to do it from within TexWorks, on the current file, you
could iterate through the necessary steps reassigning  in script a
relevent filename and run system latex etc commands/ or whatever on
it. Note the need for "cmd /c " as a prefix if under Windows.

You can then get TwWorks to open any generated files or whatever from QtScript.

From:  http://code.google.com/p/texworks/wiki/ScriptingTeXworks#Execute_arbitrary_system_commands

Here is an example for interaction with the edit contents but the
principles are obvious.

"Execute arbitrary system commands:
"Through the application object, scripts have the ability to execute
arbitrary system commands. Here is an example "System Command" script:

var cmd = target.selection;
if (cmd != "") {
  var result = app.system(cmd);
  if (result != null) {

"in a TeXworks document, then select the line ls -l and execute this
script (NB: Windows users will need to use cmd /c dir instead): the
line will be replaced by a directory listing. "
