Is there a way to run shell commands? about xkeysnail HOT 6 OPEN

I played with runuser, but it's difficult to get environment variables passed through (e.g. I need variables to disable client-side decorations etc). Instead, I've set up udev rules so that xkeysnail can run as the current user, without sudo.

First create a new group to which we allow access to the input stuff, and add this group to your user:

sudo groupadd -f uinput
sudo gpasswd -a $USER uinput

Create new udev rule granting access:

cat <<EOF | sudo tee /etc/udev/rules.d/70-xkeysnail.rules
KERNEL=="uinput", GROUP="uinput", MODE="0660", OPTIONS+="static_node=uinput"
KERNEL=="event[0-9]*", GROUP="uinput", MODE="0660"
EOF

Reboot. xkeysnail should now run OK without sudo. The launch examples I listed above now work fine.

According to the example config, there is a 'launch' command, so you can do something like this:

define_keymap(None, {
    K("print"): launch(["gnome-screenshot", "--interactive"]),
    K("Super-p"): launch(["gnome-screenshot", "--interactive"]),
}, "Global shortcuts")

I had never tried it before, but since I've been wanting to try converting my xbindkeys config to such a launch system, so I gave it a go. It works, but since xkeysnail is run via sudo, the subsequent gnome-screenshot is running as root, which is less than ideal. Does @mooz use the launch capability?

Would runuser work here?

from xkeysnail.

I think runuser would probably work with something like env DISPLAY=:0 /sbin/runuser -l username -c "/path/to/program" would be my guess.

This is going to be useful though as I am thinking about implementing something to help inspect the clipboard before just copying the contents into a terminal without warning or a previewing assuming it is multiline or has carriage returns in it.

Sorry, wrong thread.

I have an issue on my fork exploring how this might be done properly and securely.... it's not super difficult if someone wanted to implement it and test it out... (on top of my fork or even on top of the last xkeysnail 0.4.0). I don't believe any of the new things I've implemented in my fork are necessary.
