Strange triangle objects in between each block, i am guessing it have something to do with the fonts, i am using DejaVuMonoSpace Nerd Font. Is there somethin gi can do to fix this?

As the patch given in the readme doesn't works I applied this but it too throws this error

dwmblocks.c:57:12: warning: ‘returnStatus’ defined but not used [-Wunused-variable]
   57 | static int returnStatus = 0;
      |   

What should I do?

I noticed that intervals use an int value rather than float; which is potentially limiting to some use cases.

Hi,

I'm using openBSD. I see you've made some commits recently targeting OpenBSD. I'm wondering how I actually make this work?

I seeSIGUSR1 is being used as a base. If I kill -l the SIGUSR1 has a signal value of 30. If I've got a block with an update signal of 10 - I assumed I'd send either kill -40 pidofdwmblocks or pkill -40 dwmblocks - both of these fail with similar to pkill: signalling pid 52624: Invalid argument ? (I've also tried multiple numbers north of 30 to no avail)

How do you send the signal to dwmblocks to "make the magic happen" !

Thanks

Rob

When I run dwmblocks it will run for a minute or two before stopping with an error from zsh: zsh: unknown signal dwmblocks. It seems to add an extra space in the error message before dwmblocks, so I'm not sure if zsh is just parsing something wrong?

I've looked around but I can't seem to find much about this unknown signal error. Any help would be greatly appreciated!

I use Devuan Chimaera, DWM 6.2, and dwmblocks current version.
I have problem with dwmblocks, why mine cant launch automatically with .xinitrc and cool autostart dwm patch?

this is my xinitrc file

exec dwmblocks &
exec dwm

this is my dwm config.h

static const char *const autostart[] = {
"feh", "--bg-fill", "/mnt/430356562D272084/gambarrandom/Evening_on_Karl_Johan_Street.jpg", NULL,
"dwmblocks", NULL,
"mpd", NULL,
"pulseaudio", NULL,
NULL
};

Are there any plans to introduce this feature on master? I'll be more happy to help if some indication of where to start is given.

I was running an old build of dwmblocks where I had my music module (through mpd) as my first module in blocks.h. It looked something like this:

However, when I stopped (not paused) my music, the delimiter right next to it would vanish, looking like this:

I really like this behaviour and recently I updated my build to be current with this repo, since my old build did not support multicharacter delimiter. Everything works fine but when I stop my music module, the delimiter right next to it stays in place unlike the older build:

I've tried looking at dwmblocks.c but am unable to figure out what part of the code is responsible for this behaviour. I know this isn't much of an issue but I'd be glad if you could help me rectify it. Thanks in advance!

In blocks.h, you use some icons that may be missing from the extended source character set and lead to undefined behaviour.

Hi!

As mentioned in blocks.def.h, I'm trying to remove delimiters by using \0, but I seem to get these weird boxes.

I'd appreciate any help.

FreeBSD seems to be using the same signal handling as OpenBSD causing signals not to work.
FreeBSD Signal Man
OpenBSD Signal Man
The dwmblocks.c commit 480590f in pull request #55 fixes the issue by adding an OR FreeBSD to the OpenBSD defined statemens

tried to build using the makefile, it failed in ubuntu (maybe I was missing some libs but I doubt that...)
searching in the internet I came to try : gcc dwmblocks.c -lX11 -o dwmblocks which successfully compiled

hi there, been looking to chekout various dwmblock builds, where can I find your statusbar modules/scripts etc that you are using in your dwmblocks build?

After I did a format reinstall I now have funny symbols next to some emoji. I'm using Luke Smiths build of dwmblocks.

Example:

Hi, thanks for dwmblocks
I am using Luke's build of dwmblocks but added some on my own module but once in a while dwmblocks stops running which I have verified from htop. But the problem is there is no set pattern(ie time) on which this happens. To counter this problem I run

kill -HUP $(pidof -s dwm)

This refreshes dwm and dwmblocks itself but not solves the main problem.

I have a block set to update on signal 1 by sending SIGUSR1, however when I do so, the program closes as if I wanted to kill it. I'm simply running pkill -SIGUSR1 dwmblocks and instead of updating the block, the entire program is permanently killed. How do I fix this? Sorry if it's obvious, I am unfamiliar with signaling.

I'm building a ebuild for my overlay and not having a release cripples stability and patch compatibility.
And another thing, what does dwmblocks depend on (run time and build time)?

Hi there,
I seem to be getting make errors when building dwmblocks after applying dwmblocks-statuscmd-20210402-96cbb45.diff

I have a simple bash script which checks how many updates I have available and prints them with some icons, this is the code for it:

#!/bin/bash

while ! nc -zw1 google.com 443 >/dev/null 2>&1; do
  # holds the script until we have network
  sleep 2
done

# total_updates=$(yay -Qu | wc -l)
pacman_updates=$(checkupdates | wc -l)
aur_updates=$(yay -Qua | wc -l)

[[ "$aur_updates" -lt 0 ]] && aur_updates=0 # if its less than 0 we just set it to 0

# echo "Pacman: $pacman_updates"
# echo "AUR: $aur_updates"

red_bound=20

create_string () {
    count="$1"
    prefix="$2" # prefix is the letter before the symbol

    if [[ $count == 0 ]]; then
        echo "<span color='#0BDA51'>$prefix</span>"
    elif [[ $count -ge $red_bound ]]; then
        echo "<span color='red'>$prefix$count</span>"
    else
        echo "<span color='yellow'>$prefix$count</span>"
    fi
}

pacman_string=$(create_string $pacman_updates)
aur_string=$(create_string $aur_updates "Y")

package_list_path="$(chezmoi source-path)"
yay -Qe | cut -f 1 -d " " > $package_list_path/installed-packages-$HOSTNAME.txt

echo "$pacman_string $aur_string"

And when I use it with xsetroot everything works as expected, the Font Awesome characters get printed as expected. However when I call this script from dwmblocks nothing gets printed at all and the title of my current window gets printed instead:

I have fresh installed Arch Linux on my laptop yesterday and installed DWM for the WM. I also added some patches to it, which includes,

Problem

I have a simple bash script myscript.sh:

#!/usr/bin/bash

clicked="none"

case $BUTTON in
    1) notify-send hello; clicked="left";;
    3) notify-send goodbye; clicked="right";;
esac

printf $clicked

and I have this in dwmblocks/blocks.h:

//Modify this file to change what commands output to your statusbar, and recompile using the make command.
static const Block blocks[] = {
	/*Icon*/	/*Command*/		/*Update Interval*/	/*Update Signal*/
    { "my script: ", "myscript.sh", 0, 12},
};

//sets delimeter between status commands. NULL character ('\0') means no delimeter.
static char delim[] = " | ";
static unsigned int delimLen = 5;

and this in dwm/config.h:

static const Button buttons[] = {
//  ...
	{ ClkStatusText,        0,              Button1,        sigdwmblocks,   {.i = 1} },
	{ ClkStatusText,        0,              Button2,        sigdwmblocks,   {.i = 2} },
	{ ClkStatusText,        0,              Button3,        sigdwmblocks,   {.i = 3} },
// ...

What I would like to happen is for the block to display "my script: none" at first, and every time I left-click it I would like it to display "my script: left", and "my script: right" every time I right-click it.

The current behavior is that when I left-click the block, notify-send works and I get a notification saying "hello", and when I right-click it I get a notification saying "goodbye", but the $clicked variable stays the same for some reason, it doesn't change even though I update it's value after calling notify-send.

What am I missing?

Hi, I was wondering if you could help me run this on OpenBSD. In Suckless programs, you can go into config.mk and uncomment the line that it tells you will make it build on OpenBSD. But I'm not sure about here.

Can you help?

This would probably be considered more of a feature request than an "issue": I think having some way to implement "conditional" icons would be useful—for example, a different battery icon based on levels or different volume indicated based on muted/unmuted. I tried implementing this in the scripts I used themselves and tried to opt for no icon (""), and that seems to work fine, but implementing it directly into this program could be nice.

When I was using i3blocks, I was able to enter either while true; do [command]; sleep 0.1 to update a command every 0.1 seconds. Now I've read that you can use signals to tell it when to update since the program does not support floating numbers. What is the signal that I need to use for it to update? I think it was 10 when I used Linux but since I am on OpenBSD I think that it's different. However, the ones I have tried (23 and 32) do not seem to work.

I have this script that shows the SSID and signal bars of the wifi network that I'm connect to.

#!/bin/sh
SSID=$(nmcli device wifi list | grep "*" | awk '{print $3}')
BARS=$(nmcli device wifi list | grep "*" | awk '{print $9}')

echo $SSID $BARS

When I run it in my terminal (st) it shows this

I've seen it display the files in my home directory too which is weird

patching dwm with statuscmd and also using the dwmblocks patch provided in the README.md here doesn't work and i can't tell why.
however using the one in the Status monitor patches section works? should i open a pull request to change it or is it just me?

I changed from bash to zsh and my dwmblocks is not loading scripts anymore.
In zsh i can execute any scrips from .local/bin/

Hello there

So I have been using dwmblocks for a while on my desktop (running void) and have had no problem with it. last night I tried my build on my laptop (running manjaro) and it was working fine until I added a battery block, at first i assumed it had to do with my battery scripts, but that was not the case, as if I disable any of the six blocks I have, dwmblocks works fine, If i re-enable the disabled one, I get the following message

fish: “dwmblocks” terminated by signal SIGSEGV (Address boundary error)

My blocks.h file

//Modify this file to change what commands output to your statusbar, and recompile using the make command.

	{"",      "volume",				0,		 10},

	{"",      "clock",				60,		  0},

  {"",      "battery",			10,		  0},

	{"",     "internet",			60,		  0},
};

//sets delimeter between status commands. NULL character ('\0') means no delimeter.

please let me know if you need further details. thanks in advance.

clicks are working on the first two leftmost modules but after that they are not working on next modules and there's more to it. when i click on any of those modules the command of left block is called. to help you visualize, let's say i have these modules on my bar:

tags________ window title______________________________diskspace | volume | memusage | cpuusage | cputemp | date.

now, only the diskspace and volume modules work when i click on them. when i click on say, memusage or anything to the right of it, the script of volume is run with the corresponding $BUTTON variable set.
is this an issue on your side? or? my dwm patch and dwmblocks patches are correct afaik and i've spent the past 6 hours trying to find what's causing the issue, but it's all in vain. if you doubt whether i did my patches correct you can check it out at my dwm repo or dwmblocks repo. thanks!

EDIT1: i even tried luke's dwm and dwmblocks build, it's still the same so i don't think it's an issue w my build

When I run sudo make clean install I get this error:

rm -f *.o *.gch dwmblocks
cc `pkg-config --cflags x11` `pkg-config --libs x11` dwmblocks.c -o dwmblocks

I am running ubuntu 18.04 and have libx11-dev installed. Are there any other packages I need or is this broken?

Hi just wondering how I would go about this? Thanks

so since by your previous comment i realize you don't even realize how dwmblocks is actually popular, I wanted to share to you a patch made for your dwmblocks & statuscmd patch modified to be used with dwmblocks to have fully clickable modules in dwmblocks

dwmblocks + dmw statuscmd signal patch

this allows full clickability and compatibility with i3blocks modules ;)
