[SOLVED] Context-menu items for running AppImages with Firejail

[Mintymandy34]

Hello.
Newbie here.
I primarily use softwares from the Mint's Software Manager.
But sometimes I need to use latest versions of some graphical applications which aren't available over the repo.
I've used Flatpaks and AppImages for this purpose.
I like AppImages more, but I know it lacks the sandboxing feature.

So, I'm intending to run AppImages within Firejail, don't know if it's a good idea, please correct me on that.
I've successfully run AppImages from within the terminal by using the firejail command but wish to do so with the help of GUI, using context menu.

I've written this small firejail.nemo_action file and put it in ~/.local/share/nemo/actions.

Code: Select all

[Nemo Action]

Name=Open in Firejail

Comment=Open "%f" in Firejail with the default profile

Icon-Name=firetools

Exec=firejail --appimage %F

Selection =appimage

Extensions=appimage;

This feels like it works. Please correct me on that too.
But, I wish to have other options in along with that item like in a tree structure.

Example;

Code: Select all

Open in Firejail > with default profile
                 > in private mode
                 > with custom configuration

Can this be implemented here, in Nemo.
The commands are available, I need a way to implement these in a tree structure with the context menu.

Please help.


SOLUTION:

Create a file named firejail.nemo_action

Code: Select all

[Nemo Action]
Name=Open in Firejail
Comment=Open "%f" in Firejail
Icon-Name=firetools
Exec=<open_with_firejail.sh %F>
Selection=s
Extensions=appimage;
Dependencies=firejail;zenity;
EscapeSpaces=true

Create a bash file named open_with_firejail.sh

Code: Select all

#!/bin/bash
#Define Choice
CHOICE=$(zenity --forms --width 200 --title "Open with Firejail" --text "Open with Firejail options" --add-combo "Choose option." --combo-values "1. Default|2. Private|3. Offline")
case $CHOICE in
    "1. Default")
         firejail --appimage "$1";;
    "2. Private")
         firejail --appimage --private "$1";;
    "3. Offline")
         firejail --appimage --net=none "$1";;
     *)
	 firejail --appimage "$1";;
esac
exit

Copy both these files to ~/.local/share/nemo/actions and restart Nemo.

Hi,

Your action looks pretty much OK - there is one syntax error and a few fields I think you should have. I don't use firejail so not sure of it's options/arguments.

In nemo navigate to ~/.local/share/nemo/actions and click on more info in the info bar to get a commented action template.

The Selection needs to be one of {s}ingle, {m}ultiple, any, notnone, none (background click), or
# a number representing how many files must be selected to display.

You might want to make firejail a dependency, and use an EscapeSpaces line in case %F includes any spaces.

Make sure the icon name is valid or the action won't show. I normally get an action up and running and tested with no Icon-name entry initially then add the Icon-Name as the last step.

Code: Select all

[Nemo Action]
Name=Open in Firejail
Comment=Open "%f" in Firejail with the default profile
Icon-Name=firetools
Exec=firejail --appimage %F
Selection=s
Extensions=appimage;
Dependencies=firejail;
EscapeSpaces=true

As to whether you can make a nested menu entry I don't think the nemo action framework supports that other than having three main menu entries.

The way i would go is have the action call a script and use zenity in the script to pop a custom GTK dialog.....

Example of a zenity dialog...

Code: Select all

zenity --forms --width 200 --title "Open with Firejail" --text "Open with Firejail options" --add-combo "Choose option." --combo-values "1. Default|2. Private|3. Custom Config"

With the combo box open


The script will need to be executable and can live in the actions folder with the action.

So your action and it's associated script might look something like this. Note $1 in the script is the %F passed to the script by the action.

Code: Select all

[Nemo Action]
Name=Open in Firejail
Comment=Open "%f" in Firejail with choice of profile
Icon-Name=firetools
Exec=<open_with_firejail.sh %F>
Selection=s
Extensions=appimage;
Dependencies=firejail; zenity;
EscapeSpaces=true

Code: Select all

#!/bin/bash
#Define Choice
CHOICE=$(zenity --forms --width 200 --title "Open with Firejail" --text "Open with Firejail options" --add-combo "Choose option." --combo-values "1. Default|2. Private|3. Custom Config")
case $CHOICE in
    "1. Default")
         firejail --whatever-the-options-are "$1";;
    "2. Private")
         firejail --whatever-the-options-are "$1";;
    "3. Custom Config")
         firejail --whatever-the-options-are "$1";;
esac
exit

Thanks, will try this and ask you if I've any doubts.
Thanks for the help.
