launcher setting ignored in preferences.txt

In GitLab by @hamoid on Aug 12, 2021, 09:08

Description

Executing "Open Sketch Folder" on Arch Linux with i3wm and fish does not open the folder. I used to work around this by specifying a custom launcher setting. This worked in Processing 3.4, but not in later versions.

This affects very few people I guess (maybe 1?) but it would be nice if the launcher setting was enforced if present, as an override. The related lines are found here:

https://github.com/processing/processing4/blob/master/app/src/processing/app/platform/LinuxPlatform.java#L118

Expected Behavior

I can use Open Sketch Folder

Current Behavior

I can't use Open Sketch Folder. It opens a terminal window with text being printed forever in a loop.

Steps to Reproduce

Press Ctrl+K

Your Environment

• Processing version: 4.0b
• Operating System and OS version: up to date Arch Linux
• Other information: using i3 window manager

Possible Causes / Solutions

I think a solution might be to tweak the order of the if statements: if a launcher is specified, use it, otherwise, try use the default approaches. But I don't know how messy touching any of that might be.

Start in app/src/processing/app/platform/LinuxPlatform.java around line 118 and inspect how the launcher preference is selected for “Open Sketch Folder.” Reproduce the issue on Arch Linux with i3wm and fish using Ctrl+K, then verify that a configured launcher is honored and the folder opens without the terminal loop.
