As a geriatric user of sway, I don't always remember the keystrokes in the more esoteric corners of my configuration. I find that my script sway-menu helps with the bulk of the uncommon key bindings. But when I drop into a 'mode' (eg "move" mode) I don't always remember all the clever things I programed into it. nwg-wrapper to the rescue - it can display a HUD (Heads-Up-Display) of the keybindings of the mode until I exit it.
Obviously, nwg-wrapper must be installed. Your config file also needs to be changed as described in the help file.
Here's the help:
Usage: sway-mode [-c,--config config-file] [-C,--css css-file] mode
Puts sway into mode 'mode' and displays some help by extracting a
section from the config file.
Options:
-c,--config config_file location of your config file (/home/bhepple/.config/sway/config)
-C,--css css_file location of your css file (/home/bhepple/.config/nwg-wrapper/mode-help.css)
Requires nwg-wrapper https://github.com/nwg-piotr/nwg-wrapper
Assumes modes are defined in the config file like this:
mode "foobar" {
...
}
To use this, reassign the bindkey command for the mode like this:
bindsym $mod+s exec sway-mode "swap"
and in the mode definition, change the mode ending keys to
# back to default mode
bindsym q exec pkill nwg-wrapper; mode "default"
bindsym Return exec pkill nwg-wrapper; mode "default"
bindsym Escape exec pkill nwg-wrapper; mode "default"
Here's a sample CSS file:
window {
font-family: "Monospace";
color: rgba (255, 255, 255, 1.0);
background-color: rgba (255, 255, 255, 0.1);
}
#box-inner {
background-color: rgba (23, 53, 63, 0.7);
border-radius: 5px;
border-style: dotted;
border-width: 1px;
border-color: rgba (156, 142, 122, 0.7);
padding: 10px;
}
