Shitty version of rofi/dmenu using your favourite terminal, bash, and fzf. The rationale behind this being I already have a fuzzy finder and a terminal installed, so we should just glue them together. This is being dogfooded everyday by me.

install

Requires fzf and bash.

$ mkdir ~/.config/slouch/
$ touch ~/.config/slouch/hooks
$ chmod +x ~/.config/slouch/hooks

For window switching, requires xwininfo and xprop.

run

$ slouch run               # runs executables in $PATH
$ slouch drun              # runs desktop entries
$ slouch window            # switch to windows
$ slouch filter            # xdg-open files
$ cat $(ls | slouch pipe)  # fzf with a gui

config

You can override parts of slouch using a bash script in ~/.config/slouch/hooks. This 'config file' is just sourced by slouch. For instance, by default slouch assumes that you are using herbstluftwm. This means that if you have a different window manager then focusing windows won't work. To override this you can add this to your slouch config file:

__slouch_focus() {
    bspc node "$1" -f          # bspwm
    i3-msg "[id=\"$1\"] focus" # i3
    xdotool windowfocus "$1"   # should across multiple wms, but needs xdotool
}

Usually you'd want to override __slouch_term and __slouch_drun as well. By default slouch assumes that you're using st. So if you use urxvt then you might do:

__slouch_term() {
    urxvt -title slouch -geometry 80x20+570+300 -e $0 "$@"
}

__slouch_drun() {
    if [ "$1" ]; then
        __slouch_pdetach urxvt -e "$2"
    else
        __slouch_pdetach "$2"
    fi
}

To configure fzf-specific stuff you can override __slouch_fzf. E.g. if you want to add previews for files:

__slouch_fzf() {
    if [ "$1" = 'filter' ]; then
        shift
        fzf --preview='cat {} || tree {}' "$@"
    else
        shift
        fzf "$@"
    fi
}

To make slouch look better you might have to fiddle with your window manager. For instance on herbstluftwm you can add this to your autostart:

hc rule title='slouch' focus=on pseudotile=on

available hooks

Name	Description	Arguments
__slouch_focus	focus the given window	$1 = X window id
__slouch_pdetach	run and detach the given program from the shell	$@ = command to be ran
__slouch_term	run a terminal which runs the slouch script with a given argument	$@ = command to be ran
__slouch_fzf	run fzf	$1 = mode (window/drun/run/filter/...), $2,$3,... = additional arguments. If slouch pipe is invoked, then the mode is either pipe or some other text, which depends on slouch pipe <mode>
__slouch_window_ids	get a tab separated list of window IDs and window names	none
__slouch_drun	run a freedesktop entry	$1 = whether command should be ran in a terminal (empty = no), $2 = command to be executed
