Read active tab command-line args from file when reappearing

[colorfulfool]

Hi,

This one's a bit esoteric, so I understand if you don't want to merge it.

I have multiple icons that trigger better-control and, in continuation of my first PR, would be cool if it would reappear with the corresponding tab open rather than whichever was open last time:

---

There's no way to pass an argument with SIGUSR1, so instead I'm writing to a file in /tmp and have better-control read it when reappearing:

#!/usr/bin/env bash

PID=`pidof better-control`
if [ -n "$PID" ]; then
  mkdir -p /tmp/better-control
  echo $@ > /tmp/better-control/tab.txt
  kill -SIGUSR1 $PID
else
  better-control $@
fi

The script then accepts the same arguments as better-control itself:

toggle-better-control -w

I had to extract the tab argument logic because it's used in two places now, hope src/utils/tab_name.py is the right place for it.

you can open specfic tabs with the cmdline

Yes, but then I have to relaunch better-control every time, which takes about a second on my laptop. Maybe everyone else uses only top-of-the-line computers where PyGTK loads instantly, but I don't, and I'm contributing in case it's useful.

This PR reuses your command-line params logic, by the way.

im a bit short on time with some other stuff so this might take few days as i cant test it out or review for bugs

@colorfulfool so as i run the script the window just crashes without any error messages...even tho the terminal session doesnt crash the window just disappears..any idea why this might be happening?

[colorfulfool]

@quantumvoid0 You mean just the window disappears? Well, it's supposed to disappear. And reappear on the next run of the script, and so on:

output.mp4

If you mean that the program exits -- you're running the script against this version, right? Because the last released version exits upon receiving SIGUSR1.

oh well i'll test it out today (been a bit busy this month , so sorry for the late replies)

[FelipeFMA]

@quantumvoid0 have you tested it?

[quantumvoid0]

sadly i still havent , i havent gotten around to finding the time to work on BC for a while
