I want to open PDF files with Zathura on Mac. Problem is - Zathura does not have a proper App Bundle. So you cannot go in Finder to a pdf file, navigate to ‘Get Info’ and set pdf files to be opened with Zathura.
Luckily, you can create a custom App Bundle that wraps up a script that does that
But that is not as straightforward as you think it is, you can’t just execute a shell script. What if the file already opened with one of the instances of zathura process? Since Zathura is not a native OSX app, it will create a new process instance every time you open it.
The following script opens a file in Zathura, and if it was already opened, it would only activate the right window.
