[texworks] Mac OS X: request for testing

Hi Stefan,

Thanks for the example file.
I tested the minimal TeX file you sent me. Below are some reports on the issues I observed.

• Before modifying anything, when opening a TeX file containing you example, regardless of whether one has the line


and regardless of whether there is an associated PDF file, one gets a pop up window with the error message I reported.

• Before modifying anything, the menu Scripts —> Text Transforms —> Title Case (or any other choice there) do not react and do nothing.

• After having modified the Preferences according to what you suggested, when Enable QtScript debugger is chosen, a window appears showing the error message:

Sun Mar 6 14:46:42 2016 Uncaught exception at /Users/kavian/Library/TeXworks/scripts/babelLanguage.js:41: ReferenceError: Can't find variable: target

When this window is closed after having closed the source file TeXWorks crashes… But it does not crash when one closes the debugger window before the source file, and doing this the error window 

	Script "Babel language": ReferenceError: Can't find variable: target

is shown again.

• When I uncheck the boxes next to Scripts > Scripting TeXworks > Manage Scripts > Hook Scripts the above mentioned behaviour does not change. By the way, there are two instances of « Babel language » under the item Hooks. Maybe one of them is spurious?

Actually I use rather TeXShop, so the behaviour I am reporting on is in order to help you, and other developpers to nail down the culprits, and moreover these buglets are not really important.

Thanks for your work, and best regrads: OK

Which script is the error in (the filename should be displayed on the left)? Which line is the error in (pointed to by the arrow) and what is the command in that line? In addition, on the right side there should be a panel called "Locals". If you expand "Scope", you should find "TW". If you expand that as well, there should be "target". What's written next to it?

If you have a test file with or without such a command, I can test it for you if you send it to me.
