leftwm on FreeBSD 13

fyrfaras

Hello everybunny :3 ,

Recently I discovered leftwm and I wanted to try it on my FreeBSD machine.
Unfortunately it doesn't seem to work. leftwm-check tells me everything is fine. I'm using the basic_lemonbar theme.
When I start exec dbus-launch leftwm I only see the background image and the only working keybinding is the one for my terminal emulator.
Nothing else seems to work. In the console from where I initiated startx I read the following:

ERRO Cannot open old state: No such file or directory (os error 2)
~/.config/leftwm/themes/current/up: line 31: tac: command not found
sed: 1: "/^\s*$/d": RE error: trailing backslash (\)
thread main panicked at 'failed printing to stdout: Broken pipe (os error 32)', library/std/src/io/stdio.rs:1197:9
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

Does somebody run leftwm successfully or encountered the same problem on FreeBSD?

I'm using FreeBSD 13.0-RELEASE-p4 amd64 with a generic kernel and installed leftwm version 0.2.11 from the binary package repository (latest).

Bunny regards

PS: I hope I address this here correctly. If not many apologies in advance =w="

fyrfaras It's actually telling you exactly what it's wrong,

~/.config/leftwm/themes/current/up: line 31: tac: command not found
sed: 1: "/^\s*$/d": RE error: trailing backslash ()

What shell are you using?
Can you maybe post your up script?

Depending on your shell, this on the default script

sizes=( $(leftwm-state -q -n -t $SCRIPTPATH/sizes.liquid | sed -r '/^\s*$/d') )

might need to be adjusted.

I'm running leftwm-git but, on NetBSD and I have the following up script,

#!/bin/sh

export SCRIPTPATH="$( cd "$(dirname "$0")" ; pwd -P )"

# Down the last running theme
if [ -f "/tmp/leftwm-theme-down" ]; then
    /tmp/leftwm-theme-down
    rm /tmp/leftwm-theme-down
fi
ln -s $SCRIPTPATH/down /tmp/leftwm-theme-down

# Start picom
if [ -x "$(command -v picom)" ]; then
  picom --config $SCRIPTPATH/picom.conf &> /dev/null &
fi

# Define theme.toml
echo "LoadTheme $SCRIPTPATH/theme.toml" > "$XDG_RUNTIME_DIR"/leftwm/commands.pipe

# Set wallpaper
if [ -x "$(command -v feh)" ]; then
  feh --bg-fill $SCRIPTPATH/wall.jpg
fi

# Start lemonbar and pipe leftwm status into it
sizes=$(leftwm-state -q -n -t $SCRIPTPATH/sizes.liquid | sed -r '/^s*$/d')

index=0
for size in ${sizes}
do
   leftwm-state -w $index -t $SCRIPTPATH/template.liquid | lemonbar -f 'Fantasque Sans Mono Nerd Font Complete Mono:style=Regular:pixelsize=10' -g $size -F#C0C5CE -B#BD282828&
   let index=index+1
done

Note: you need lemonbar-xft to be able to use ttf fonts, so don't just copy/paste.

fyrfaras Yeah. As @pin pointed out, tac doesn't exist on FreeBSD, but, it's very easy to make one:

`tac(1)`

#!/bin/sh
#
# tac(1) using tail -r

# remove all flags
#
while :
do	case "$1" in
	--)	shift
		break
		;;
	[-+]*)	shift
		;;
	*)	break
		;;
	esac
done
exec tail -r -- "$@"

Just the last line alone will do, actually.

Bunny apologies for my late reply. As soon as I saw your lovely replies I jumped into action :3c
Thank you very much for your help, pin and rvp ! The wm seems to properly run now.
I can use the keybindings, the lemonbar and I'm quite satisfied so far and happy ^w^

pin What shell are you using?
Can you maybe post your up script?

I switched for leftwm back to bash(1). Before that I was using tcsh(1).
Regarding the up script. I used yours and modified it according to your advice.
I will post it in a separate reply.

rvp Yeah. As @pin pointed out, tac doesn't exist on FreeBSD, but, it's very easy to make one:

I used your provided script to get the demanded tac functionality, thank you :3

fyrfaras I can use the keybindings, the lemonbar and I'm quite satisfied so far and happy ^w

Great!

fyrfaras I switched for leftwm back to bash(1)

No need to do that, just adjust the scripts a bit to fit your shell.

As promised my up script. I guess I will dive into lemonbar(1) to modify it for my needs now ^^

#!/bin/sh

export SCRIPTPATH="$( cd "$(dirname "$0")" ; pwd -P )"

# Down the last running theme
if [ -f "/tmp/leftwm-theme-down" ]; then
    /tmp/leftwm-theme-down
    rm /tmp/leftwm-theme-down
fi
ln -s $SCRIPTPATH/down /tmp/leftwm-theme-down

# Start picom
if [ -x "$(command -v picom)" ]; then
  picom &> /dev/null &
fi

# Define theme.toml
echo "LoadTheme $SCRIPTPATH/theme.toml" > "$XDG_RUNTIME_DIR"/leftwm/commands.pipe

# Set wallpaper
if [ -x "$(command -v feh)" ]; then
  feh --bg-fill $SCRIPTPATH/rom_wallpaper.png
fi

# Start lemonbar and pipe leftwm status into it
sizes=$(leftwm-state -q -n -t $SCRIPTPATH/sizes.liquid | sed -r '/^s*$/d')

index=0
for size in ${sizes}
do
   leftwm-state -w $index -t $SCRIPTPATH/template.liquid | lemonbar -g $size -F#FFFFFFFF -B#AA222222&
   let index=index+1
done
