rotop's Issues

Don't use `top` to get process status

Issue

Current implementation runs top command and parses the result
It may not work on environments other than Linux
Also, running top consumes CPU

Idea

Use psutil to get process status

rotop does not work on tmux with `init_extended_color() returned ERR` error

Thank you for the tool, it is very useful!!

But unfortunately rotop failed in some of my environment with the following message:

$ rotop
rotop version 0.1.4 by iwatake2222
Traceback (most recent call last):
  File "/home/minoda/.local/bin/rotop", line 8, in <module>
    sys.exit(main())
  File "/home/minoda/.local/lib/python3.10/site-packages/rotop/rotop.py", line 82, in main

    curses.init_color(0, 0, 0, 0)
_curses.error: init_extended_color() returned ERR

After doing some quick research, it seems that the tmux is the cause here.

$ echo $TERM
tmux-256color

This is not critical since l can use this tool by exiting the tmux first and then executing it anyway, but since I was not sure how to fix it, would be glad if anyone could solve this issue. Thanks!

Feature request: Option to only show ROS node processes

First, thanks a lot for programming this helpful tool. I was looking for a small tool like this since some time, as it is very annoying to find out how much CPU load one node generates.
I think it would be great if there was an option like "--only-ros" which then only shows processes belonging to ROS nodes (and no other processes that are running, e.g. Firefox). I guess most people are actually just interested in these node processes and the long list of other processes makes the GUI less clear.
