[TxMt] Re: LaTeX bundle wont stop opening TeXShop

[Angelo Varlotta]

Hi René,
I was holding back before replying this time so that I could try more
thoroughly your bundle. So far, the compiled version of
refresh_viewer.scpt seems to be playing nicely. I haven't found any
issues, TeXShop doesn't open after successive LaTeX compiles. I've
installed your bundle according to your instructions in the previous
email, and I made sure that the default LaTeX version is unselected, no
other versions of LaTeX are present and that your bundle is cloned from
Github in the Avian directory. So far, things are looking good with this
LaTeX bundle!

Cheers,
Angelo

I believe this “silent” launching is the behaviour that I encountered when describing the growing and shrinking of my Dock when `texmate`  called (the uncompiled script) `refresh_viewer.scpt`.

This could be because either the compiled version is much faster, or as pointed out by the Stack Overflow article mentioned by Jim [3], that compiled version of AppleScripts do not open Applications if they do not need to.

Could you please try to remove all LaTeX bundles and then clone the one from GitHub (again). After that, if the problem continues, please try to open `refresh_viewer.scpt` inside `Support/bin` with “Script Editor”. If that works, then it seems something overwrites the bundles content. If it does not, then I guess I have to come up with better solution to fix the command.

If I remove “TeXShop”, open “Skim” and then run the `refresh_viewer.scpt Skim some.pdf`, where `refresh_viewer` is the uncompiled AppleScript I get no error.
