Custom Menus

Walker is just a frontend that interacts with a backend, Elephant: https://github.com/abenz1267/elephant Elephant allows you to create custom menus via its menu provider. Running elephant generatedoc will generate markdown output of every installed provider and it's configuration options. It also includes examples for custom menus. \

Static Menus Examples

name = "other"
name_pretty = "Other"
icon = "applications-other"

[[entries]]
text = "Color Picker"
keywords = ["color", "picker", "hypr"]
actions = { "cp_use" = "sleep 0.5 && wl-copy $(hyprpicker)" }
icon = "color-picker"

[[entries]]
icon = "zoom-in"
text = "Zoom Toggle"
actions = { "zoom_use" = "hyprctl -q keyword cursor:zoom_factor $(hyprctl getoption cursor:zoom_factor -j | jq '(.float) | if . > 1 then 1 else 1.5 end')" }

[[entries]]
text = "Volume"
async = "echo $(wpctl get-volume @DEFAULT_AUDIO_SINK@)"
icon = "audio-volume-high"

[entries.actions]
"volume_raise" = "wpctl set-volume @DEFAULT_AUDIO_SINK@ 0.1+"
"volume_lower" = "wpctl set-volume @DEFAULT_AUDIO_SINK@ 0.1-"
"volume_mute" = "wpctl set-volume @DEFAULT_AUDIO_SINK@ 0"
"volume_unmute" = "wpctl set-volume @DEFAULT_AUDIO_SINK@ 1"
"volume_set" = "wpctl set-volume @DEFAULT_AUDIO_SINK@ %VALUE%"

[[entries]]
keywords = ["disk", "drive", "space"]
text = "Disk"
actions = { "disk_copy" = "wl-copy '%VALUE%'" }
async = """echo $(df -h / | tail -1 | awk '{print "Used: " $3 " - Available: " $4 " - Total: " $2}')"""
icon = "drive-harddisk"

[[entries]]
text = "Mic"
async = "echo $(wpctl get-volume @DEFAULT_AUDIO_SOURCE@"
icon = "audio-input-microphone"
actions = { "mic_set" = "wpctl set-volume @DEFAULT_AUDIO_SOURCE@ %VALUE%" }

[[entries]]
text = "System"
async = """echo $(echo "Memory: $(free -h | awk '/^Mem:/ {printf "%s/%s", $3, $2}') | CPU: $(top -bn1 | grep 'Cpu(s)' | awk '{printf "%.1f%%", 100 - $8}')")"""
icon = "computer"

[[entries]]
text = "Today"
keywords = ["date", "today", "calendar"]
async = """echo $(date "+%H:%M - %d.%m. %A - KW %V")"""
icon = "clock"
actions = { "open_cal" = "xdg-open https://calendar.google.com" }

[[entries]]
text = "uuctl"
keywords = ["uuctl"]
icon = "applications-system"
submenu = "dmenu:uuctl"

... and here is a more simple one!

name = "bookmarks"
name_pretty = "Bookmarks"
icon = "bookmark"
action = "xdg-open %VALUE%"

[[entries]]
text = "Walker"
value = "https://github.com/abenz1267/walker"

[[entries]]
text = "Elephant"
value = "https://github.com/abenz1267/elephant"

Dynamic Menu Example

By default, the Lua script will be called on every empty query. If you don't want this behaviour, but instead want to cache the query once, you can set Cache=true in the menu's config.

Name = "luatest"
NamePretty = "Lua Test"
Icon = "applications-other"
Cache = true
Action = "notify-send %VALUE%"
HideFromProviderlist = false
Description = "lua test menu"
SearchName = true

function GetEntries()
    local entries = {}
    local wallpaper_dir = "/home/andrej/Documents/ArchInstall/wallpapers"

    local handle = io.popen("find '" ..
        wallpaper_dir ..
        "' -maxdepth 1 -type f -name '*.jpg' -o -name '*.jpeg' -o -name '*.png' -o -name '*.gif' -o -name '*.bmp' -o -name '*.webp' 2>/dev/null")
    if handle then
        for line in handle:lines() do
            local filename = line:match("([^/]+)$")
            if filename then
                table.insert(entries, {
                    Text = filename,
                    Subtext = "wallpaper",
                    Value = line,
                    Actions = {
                        up = "notify-send up",
                        down = "notify-send down",
                    },
                    -- Preview = line,
                    -- PreviewType = "file",
                    -- Icon = line
                })
            end
        end
        handle:close()
    end

    return entries
end

You can call Lua functions as actions as well:

Actions = {
    test = "lua:Test",
}

function Test(value, args)
    os.execute("notify-send '" .. value .. "'")
    os.execute("notify-send '" .. args .. "'")
end
