This is a small shell modi script for rofi for presenting keybinding hints. It is intended for use with the i3 window manager but it's also able to display keybindings from any suitably formatted config file.

The program functions by scanning and parsing comments in a specific format (use by regolith remontoire tool and described directly below), then displaying them in rofi.

This script utilizes the concept of a category to group items, action to denote the human description, and keybinding to define the specific keys corresponding to the action. The format is designed to be both easily parsable by program but also readable in it's native form by people:

## <category> // <action> // <keybinding> ## <reserved for user notes>

Text within <category>, <action>, and <keybinding> must not contain the sequences ##, //, or line feeds.

Examples:

...
## Navigate // Relative Window // <Super> ↑ ↓ ← → ##
bindsym $mod+Left focus left
...
## Launch // Application // <Super> Space ## some extra notes that are ignored by Remontoire but maybe of interest to those reading the config file.
bindsym $mod+space exec $i3-wm.program.launcher.app

Any line that doesn't contain the structure listed here will be ignored.

You need:

• rofi >= 1.6.0
• xmlstarlet package (use to escape input for pango markup).
• i3-msg binary from i3 in order to launch the command associated to the shortcut.

Update the CACHE_FILE and CONFIG variable to your need or set and export them before calling the rofi command.

Launch the script with:

rofi -modi shortcut:~/full/path/to/shortcut.sh -show shortcut

You may add the following bindsym in you i3 config file:

# For french keyboard
## System // Shortcut help //  ? ##
bindsym $mod+shift+comma exec rofi -modi shortcut:~/.config/rofi/scripts/shortcut.sh -show shortcut

Selecting a shortcut launch the associated command via i3-msg.
