Using with flatpak apps

[ceranco]

Hello, I'm greatly enjoying using jumpapp, but I've recently hit a snag.

I've installed MellowPlayer using flatpak, and when I run jumpapp MelloPlayer when it's running it fails with the following error:

Error: found running process for 'MellowPlayer', but found no window to jump to

I'm not sure what's happening, as the window is open:

Thanks in advance!

Try to launch it with the -f option jumpapp -f MellowPlayer

Hi @Lupccs, thanks for the quick response!

Running jumpapp -f MellowPlayer fails with the following message:

Error: unable to find command 'MellowPlayer'

I think it might be because the only way to start flatpak apps is to run flatpak run <APP_ID>, so MellowPlayer doesn't exist in the PATH.

Either way, turns out that simply running flatpak run com.gitlab.ColinDuquesnoy.MellowPlayer will start a new instance, or focus the existing window if it already exists, so that's good enough for me.

Thanks again!

I think that support for Flatpak apps would be useful -- though perhaps problematic to implement because of how they're launched.

If anyone came here looking for a fix or a workaround (as I did), try this:

1. Create a file somewhere in your <PATH> named after the program you want to launch (no extension).
2. Make the file executable (chmod +x <FILE_NAME>)
3. Add this bit of code to the file:

   nohup flatpak run <APP_ID> </dev/null >/dev/null 2>&1 &

   Breakdown of what this code does:	code	description
   nohup	nohup is a POSIX command to ignore the HUP signal
   flatpak run	command used to launch any Flatpak command from terminal
   <APP_ID>	the application ID which can be retrieved by running flatpak list; the ID will have (at least) three phrases separated by two periods, like com.spotify.Client or com.gitlab.ColinDuquesnoy.MellowPlayer
   </dev/null >/dev/null	redirecting input and output to the null file so it doesn't get written to nohup.out (which is nohup's default behavior)
   2>&1	2>&1 redirects the standard error to the standard output so they appear together and can be jointly redirected to a file. (Writing just 2>1 would redirect the standard error to a file called "1", not to standard output.)
   The final &	launches the application in the background, detached from the terminal
