How to restart ES from a script?

meleu

@cyperghost yep, but as you can see here in emulationstation.sh, removing the /tmp/es-restart shouldn't be a user's task.

That emulationstation.sh is the piece of code responsible to manage what happens with the user's choice on ES Quit menu (restart ES, quit ES, restart system, shutdown system).

@meleu thanks so much! Gotta get the kids to daycare, will test out in about 45 minutes.

@meleu I merged your changes and loaded into my pi, the script fails t launch. I noticed a few things:

the menu dialog functions were not present
the script that was on github was not updated to reflect the permission changes per the retropie setup script changes. sudo needs to be added in front of the rm and cp commands now. I hadn't updated because that was the last working script using @cyperghost command.

I took your modifications and merged them with the dialog text and the sudo commands and i still get the same issue. When i go to the start menu, select quit, and then any function i see a flash of script and a restart. This newer code does not seem to change anything.

I have added a second branch, branch v2 to the github repository. github v2 If you and @cyperghost could look at the v2 script and possibly download it and try to run it from the retropie menu that would be great.

Thank you both for your time and help.

@TMNTturtlguy I will only have a chance to look at it tomorrow... But I'll try. Cheers!

@meleu Not a problem! No rush, I appreciate all the help. Thanks

@TMNTturtlguy I think first @meleu should take a look on your script. If there are still issues with it then I build a "restart binary" based on my script but that will analyze processes and kills always the right one ... so there are no future issue okay?

But I think Master meleu finds an easy solution....

TMNTturtlguy

@cyperghost i agree! I appreciate both of your guys help. In the mean time i will keep tinkering with it and the script works fine without the auto restart function. You just have to manually restart, so for the time being I can still accomplish what I want.

@TMNTturtlguy out of curiosity: you need a keyboard to choose an option on your script, right? Or is it able to get input from joystick?

TMNTturtlguy

@meleu the way it is written now it works from joystick/controller. The whole point is that i want to be able to make the ES changes without a keyboard. It works great right now with joystick and ps4 controller, less the restart issues. Thanks

This is curious. I can't see any mention to joy2key in your script. And joy2key is the tool responsible to convert the up/down/left/right on d-pad to up/down/left/right key presses (and A button to <enter>).

Can you confirm that you navigate through your dialog menu using the up/down in your joystick and select an option with the button A?

@meleu
Yes It's working with D-Pad A and B
even this minimal menu works

#!/bin/bash
# Bash Menu Script Example

dialog --clear --backtitle "Backtitle here" --title "Title here" --menu "Choose one of the following options:" 15 40 4 \
1 "Option 1" \
2 "Option 2" \
3 "Option 3"

@meleu @TMNTturtlguy @BuZz Man I'm so ....
pkill -n emulationstatio always kills the newest process that the short version what my script exactly does. With all advantages and disadvantages - but the shortest script ;)

I should more RTFM

Really neat! :-) It seems to be a cool RetroPie feature, because if you launch the script directly from command line you can't use joystick for that.

Maybe we can make a video like this below replacing pumpkin by emulationstation:

@meleu Is this always the same pumpkin? I think a pumpkin always got's seven lives.

I think one is a binary, two or three are scripts, and the others were launched in an infinite loop inside some of those scripts.

What about Schrödinger's pumpkin?

TMNTturtlguy

@meleu @cyperghost I tried to create the restart function as a separate choice from the menu, thus you first pick an option for which config file to load and then choose to restart. I tested with several of the variations of the restart command and each time I get similar results. The script works fine, but after running it, the start/quit menu runs an auto restart, no different than when the restart command is within the actual config change function. I am at a loss, like charlie brown waiting for the great pumpkin to appear :)

@TMNTturtlguy what's the version of your RetroPie-Setup? It must be 4.2.8+

TMNTturtlguy

@meleu I am not at my pi right now, but i updated again about 12 hours ago, so it is the current version as of then.
