Re: Dmenu Hacking Thread

I found out that you can use baloo without kde. I wrote a simple python script that pipes baloo matches into dmenu.  To use it, first run the following commands:

balooctl enable
balooctl start

"balooctl start" needs to be run on login, so put it in your .xinitrc, or whatever. The script uses xyne's mimeo (an alternative to xdg-open) as it seems to open files faster than standard xdg-open, but you can replace this if you want. Name it whatever you want, e.g. mysearch. If you give it search terms as an argument it will use those, otherwise it will prompt you.

Re: Dmenu Hacking Thread

Any help combining 2 dmenu scripts into one?

I have a simple google search dmenu script that I call with a keybinding

#!/bin/bash
DMENU='dmenu -l 12 -x 200 -y 30 -w 600 -nb '#4E4E4E' -nf '#eeeeee' -sb '#5E656B' -fn Inconsolata-12'

GS=`echo | $DMENU $*`
firefox -new-tab http://www.google.co.uk/search?q="$GS"

My main Dmenu script is called with another keybinding but I would like to combine them into one script but I am too stupid to know how.
How would I add the above simple code into the more full featured version below that does the normal Dmenu stuff plus also reads an alias file so I can run alias commands.
I would like to be able to type a comma , then a search term to do the google search part, but if I don't type a comma it behaves like
the regular Dmenu.
My Main Dmenu script is:

#!/bin/bash
cachedir=${XDG_CACHE_HOME:-"$HOME/.cache"}
if [ -d "$cachedir" ]; then
	cache=$cachedir/dmenu_run
else
	cache=$HOME/.dmenu_cache # if no xdg dir, fall back to dotfile in ~
fi

if [ -f ~/.dmenu_alias ]; then
	aliases=( ~/.dmenu_alias )
elif [ -f ~/.zsh_aliases ]; then
	aliases=( ~/.zsh_aliases )
else
	touch ~/.dmenu_alias
fi

if [ ~/.bash_functions ]; then
	functions=( ~/.bash_functions )
elif [ ~/.zsh_functions ]; then
	functions=( ~/.zsh_functions )
else
	touch ~/.bash_functions
fi

source $aliases

cmd=`(
	IFS=:
 if stest -dqr -n "$cache" $PATH || stest -fqr -n "$cache" "$aliases" || stest -fqr -n "$cache" "$functions"; then
          (
            stest -flx $PATH
	    	alias | awk -F '[ =]' '{print $2}'
	    	compgen -A function
          ) | sort -u | tee "$cache" | dmenu -l 14 -x 200 -y 30 -w 650 -nb '#4E4E4E' -nf '#eeeeee' -sb '#55C43B' -fn -misc-fixed-*-*-*-*-20-200-*-*-*-*-*-* "$@"
	else
		dmenu -l 14 -x 200 -y 30 -w 650 -nb '#4E4E4E' -nf '#eeeeee' -sb '#55C43B' -fn -misc-fixed-*-*-*-*-20-200-*-*-*-*-*-* "$@" < "$cache"
	fi
)`

if [ -f ~/.bash_alias ] || [ -f ~/.zsh_aliases ]; then
	if [ ! -z "$(grep '^alias' $aliases|cut -d'=' -f1|grep $cmd)" ] || [ -z $(which $cmd) ]; then
		echo -e "source $aliases \n $cmd" | bash -O expand_aliases &
	else
		exec $cmd &
	fi
fi

Re: Dmenu Hacking Thread

ok will try that as it's probably the simplest, at the moment I am just using dmenu to choose between the google seach dmenu script or the general script as I havent found out how to combine them

choice="
gg '/home/dka/bin/dmenu-gs'
nn '/home/dka/bin/dmenu-aliases-multi'
"
result=$(echo "$choice" | dmenu -fn "-misc-fixed-*-*-*-*-20-200-*-*-*-*-*-*" -nb "#000000" -nf "#e0e0e0" -sb "#000000" -sf "#4abcd4")
cmd=$(echo "$result" | cut -d' ' -f2-)
[ -n "$cmd" ] && eval setsid setsid "$cmd"

Yes the alias idea works fine, I just typ ,gg  in my general dmenu
then I get another box that opens to type in my search term.

Re: Dmenu Hacking Thread

A wrapper for pass, the simple password manager.

#!/usr/bin/env sh

# Default environment variables - see man pass (1):
[ -n "$PASSWORD_STORE_DIR" ] || export PASSWORD_STORE_DIR="$HOME/.password-store"
[ -n "$PASSWORD_STORE_CLIP_TIME" ] || export PASSWORD_STORE_CLIP_TIME=45

cd "$PASSWORD_STORE_DIR"
passname="$(find * -type f | sed 's/\.gpg$//g' | dmenu "$@")"
[ -n "$passname" ] || exit 1
pass show -c "$passname" >/dev/null
notify-send \
	'Unix pass' \
	"$passname\n(will clear in $PASSWORD_STORE_CLIP_TIME seconds)"

EDIT (fix default $PASSWORD_STORE_DIR - it doesn't like the tilde)

Thanks! I didn't know of this. `pacman -Ql pass` doesn't list those files, though. The vim snippet is pretty useful.

Yes, my recollection is you need the aur package.

Re: Dmenu Hacking Thread

There are already several dmenu-based file managers, but here's
another one anyway... (I had fun writing it, I hope can be useful to
some people). See "fmenu --help" for details.

I invoke it as "fmenu -f -c -d" via a keyboard shortcut.

Maybe I'll try implementing favorites and/or bookmarks someday (yes, I
got somewhat carried away).

#!/bin/bash

# Defaults. {{{
showflags=false
showcurrent=false
replacehome="~"
maxcurrent=35
dmenuopt="-b -i -fn Monospace-12:normal"
file=$(pwd)
# }}}

# Help. {{{
if [[ "$@" =~ "--help" ]]; then
cat << EOF
USAGE:
  fmenu [OPTIONS]... [PATH]
  Launch fmenu in PATH, present working dir otherwise.

  If a non-dir is selected, it is opened with the default application
  if it is a file, otherwise it is executed, so e.g. entering "xterm"
  after navigating to some dir open the terminal in that dir.

  If the value entered begins with "*" followed by one or more letters,
  it is interpreted as a flag selector, turning on/off the following
  options:
    d   Sort directories before files.
    a   Show all files (including dotfiles).
    t   Sort by modification time.
    r   Reverse sort.
    s   Sort by size.
    x   Sort by extension.
  For instance "*sr" sorts by increasing size if those options where unset.

OPTIONS:
  --help     Show this message.
  -f         Show ls flags in the prompt.
  -c         Show current dir in the prompt.
  -h=STRING  Replace \$HOME at the beginning of the current dir in the prompt with STRING.
             Default is "~". If STRING is empty, nothing is done.
  -m=NUM     Max length of the prompt. If it is larger, the head is truncated.
             Default is 35.
  -o=STRING  Passes STRING as options to dmenu; default is "$dmenuopt".
  -d, -a, -t, -r, -s, -x
             Turns on the associated *-flag, see USAGE above.

since pass was already mentioned. I also created one. using rofi though, so at least the header menu and the exit codes wont work with standard dmenu.

Cool. You can lose some processes by just relying on awk, if you are so inclined...

custom=$(cat $HOME/.config/rofi-surfraw/searchengines | awk -F ' - ' '{ print $1 }')

Could be felineless:

custom=$(awk -F ' - ' '{ print $1 }' $HOME/.config/rofi-surfraw/searchengines)

Also,

list=$(sr -elvi | awk '{ print "?"$1 }' | tail -n +2)

can be awkified:

sr -elvi | awk '{if (NR!=1) print "?"$1 }'

Similarly grep and awk is redundant, just use awk's pattern matching.

Re: Dmenu Hacking Thread

This is for unmounting devices mounted by udevil and devmon
(Just don't label your devices "[ALL]" )

With dmenurc I pass dmenu flags only, not the entire dmenu string, so I think you can replace it easily if you use rofi.

Attention: it doesn't work if your labels contains spaces.

#!/usr/bin/env bash

conf="$XDG_CONFIG_HOME/dmenu/dmenurc"
[[ -r $conf ]] && . "$conf"

# where drives are mounted by udevil/devmon
media_mounts="/media/$USER"

drive=$((awk -v mounts="$media_mounts/" '$0 ~ mounts { gsub(mounts,"",$2); print $2 }' /etc/mtab; printf "[ALL]") | dmenu "${dmenuopt[@]}" -p Unmount "$@")
case "$drive" in
    "")
        exit
        ;;
    "[ALL]")
        awk -v mounts="$media_mounts/" '$0 ~ mounts { system("udevil unmount " $2) }' /etc/mtab
        still_mounted=$(awk -v mounts="$media_mounts/" '$0 ~ mounts { gsub(mounts,"",$2); print $2 }' /etc/mtab)
        if [ -z "$still_mounted" ]; then
            notify-send Unmounted "Every shares and removable drives"
        else
            notify-send -u critical Error "There are still mounted devices: $still_mounted"
        fi
        ;;
    *)
        udevil unmount "$media_mounts/$drive"
        if [ $? -eq 0 ]; then
            notify-send Unmounted "$drive"
        elif [ $? -eq 1 ]; then
            notify-send -u critical Error "$drive is busy"
        else
            notify-send -u critical Error "Something's very wrong! ;)"

thanks @masque, I like it.
It's work well with rofi.

Warning with labels who contains a space character.
In my mtab the space is encode '\040'

Re: Dmenu Hacking Thread

Simple application menu that pops up on cursor openbox style. Requires xdotool, xdpyinfo, xdg-open and dmenu patched for height, x, y and preferrably mouse. It also uses as run dialog slightly modified version of dmenu_recent which has been posted earler on this thread. All of my menus source .dmenurc for theming options, and try to copy it from /usr/share/dmenu/dmenurc if it does not exist. Some menuitems also use custom scripts (terminal is wrapper for urxvt), but they can be easily modified and more can be added.

The difference between reality and fiction is that fiction has to make sense.

Re: Dmenu Hacking Thread

thanks @masque, I like it.
It's work well with rofi.

Warning with labels who contains a space character.
In my mtab the space is encode '\040'

I noticed that...
I ain't expert with awk syntax. Do you know how could I fix it?

Re: Dmenu Hacking Thread

I have made a near fully functional irc client out of dmenu, sh, a window manager and ii (The actual irc handler). It can send messages to servers and channels (+nicks, aka pm's), read recent messages, read persistent messages, dump log files, auto complete nicks at the start of messages to a channel, copy a message's contents to xsel, get notifications of new messages (Doesn't pop up, but a keybind shows you where new messages are), auto-connect to servers, leave channels, and "paste" messages from xsel. The only thing I can think it can't do is leave servers, but I couldn't find ii functionality for that. Here is the actual dmenuirc.sh:

#!/bin/sh

templog=~/.dmenuirc/tempirc
fulllog=~/.dmenuirc/logs

}

bindsym $mod+p mode "irc"
}

bindsym $mod+p mode "irc"

Basically kills all old instances, cleans dirs, then launches autorun everytime the wm is reloaded. In the autoii.sh, just run seperate instances of ii for each server like "ii -s irc.freenode.net -n aftix &". In theory you should be able to auto identify with the nickserv or auto join channels in autoii, but ii doesn't instantly create the files required so you'd need a wait command.
The "fix" is for one slight issue - Sometimes, seemingly at random, you're notification for a channel/server will be stuck on but there won't be new messages. Use the fix to fix this and read through the persistent messages to check for any lost ones.

Re: Dmenu Hacking Thread

I added experimental gtk support to my "HUD dmenu":
https://github.com/tetzank/qmenu_hud

As i don't use many gtk applications, it would be nice if someone else could give it a try. You need to install the unity-gtk-module for gtk support: https://aur.archlinux.org/packages/unit … alone-bzr/

Re: Dmenu Hacking Thread

On the suckless mailing list this problem was solved in a VERY nice way!

This script depends on lsw, which is also a suckless project and available in the AUR.

#!/bin/bash

declare -i active_id
declare -i win_id

winlist=$(xprop -root _NET_CLIENT_LIST|cut -d "#" -f 2|tr "," " ")
count=$(echo $winlist|wc -w)
active_id=$(xprop -root _NET_ACTIVE_WINDOW|awk -F' ' '{ print $NF }')
foo=$(for i in $winlist; do
        win_id="${i}"
        if [ $win_id -eq $active_id ]; then
                focustag="*"
        else
                focustag=" "
        fi
          
        win_class=$(xprop -id ${win_id} WM_CLASS | cut -d'"' -f2)
        win_title=$(xprop -id ${win_id} WM_NAME | cut -d'=' -f2-)
        printf  "%10.10s${focustag}| %60.60s | 0x%7.7x\n" "${win_class}" "${win_title}" "${win_id}"
done |sort| dmenu -i -l $count)


if [ $? -eq 0 ]; then
        xdotool windowactivate $(echo $foo | awk -F'|' '{ print $NF }')
fi

Works for firefox and libreoffice as well. Perfect! (Slowly but surely it's getting hard to find a not already used shortcut for all those fine dmenu tools!)

Cannot figure out where is the dependency on lsw (it seems to run OK without lsw installed).

Re: Dmenu Hacking Thread

I have a question to dmenu users. On my machine transitions between menus occur not instantly: on pressing Enter, the new menu appears in about 0.3-0.5 seconds after the old menu disappears, which looks like constant flashing or flickering during menu navigating. Is such delay between menu transitions normal? Could it be reduced somehow?
