Showing live stdout from extension (original) (raw)

February 2, 2025, 10:21pm 1

I’m writing a GNOME panel indicator extension. Clicking on the indicator shows a menu where each item is a shell command (e.g. ping localhost), and clicking on an item runs the command.

The commands are run using Gio.Subprocess.new(), creating long-lived processes (i.e. the processes don’t exit immediately).

My question is as follows:

How can I show the process’ stdout/stderr in an updating fashion?
I Imagine a scrollable window popping up, showing the output as it is arrives (resembling a terminal window, except that you can’t input anything into it).

Is there a standard way of implementing this kind of window in GNOME extensions?
Is there an extension which does something similar (graphically speaking)?

I couldn’t find an answer to both of the last questions.

Thank you very much!

https://github.com/anybotics/gnome-shell-ping-monitor-applet might be close enough, but the extension has not been updated for past few years.
