[ WAYBAR MODULE *EOL* ] Notifications for Arch Linux package updates

DISCLAIMER: The module is unmaintained, since I've gone systemd-free

Scope/Features:

  • Notifications/Information only (no install shortcuts etc.)

  • Official packages only (I prefer handling the AUR separately)

  • Quick access to information about all available updates (waybar's tooltip is not meant for large amounts of info, imho)

  • Highlight most recent updates (fuzzy searchable)

  • Dynamic icon (5 different states, animated notifications)

  • Modularity (by using temporary files, which can be accessed by additional tools/scripts)

  • Simplicity (just a few lines of code, really)

  • Why?⁽¹⁾

Languages: Shell, Python, CSS

Run the script 'updatenotif.sh' at startup of your graphical environment (or you can use the systemd user service - see "Development" below). It will check for updates every ~30 minutes - you can manually refresh the database any time by right-clicking on the icon.
Please place script files (*.sh, *.py) inside '~/.local/bin/' and don't forget to make the shell scripts (*.sh) executable.
(It may be worth noting that I've appended comments to values that can be modified without breaking the module - given that the syntax is correct)

updatenotif.sh:

#!/bin/bash
#
#[v4.0.5]
#
# This script depends on 'pacman-contrib'

For more info on how to add the module to waybar, please consult:
https://github.com/Alexays/Waybar

# Screenshots (depicted icons differ from those used in the module - see "NOTE" below):

HfF-.png

Animated notifications:
HfFz.png HfFi.png

Tooltip: Total count is followed by the timestamp of the last sync, new updates count is followed by the timestamp of their notification - in case you missed it smile:
HfFr.png
(The update count can either be hidden or shown (new default) on the bar - see "format" examples inside the module)

Menu feature (fuzzel):
Hfhh.png

HfFs.png

NOTE: Since the update of 'ttf-nerd-fonts-symbols' to v3 the codepoints of the original icons used cannot be pasted here on bbs anymore, hence I replaced them with the more generic "(smiley) face" ones. The "package" ones including their old and new codepoints can be found here (search terms: "package", "hexagon").
Inside the module, their order is:
HfFc.png
Placeholders used in the module:
HfFT.png
In case some icons are missing/aren't rendered correctly, you may want to install a 'nerd-font'...

The module has no immediate way of telling whether you issued 'pacman -Syu' (out-of-scope*), so you will have to let it know. This can either be achieved by simply right-clicking the icon, or by doing the update like this (I recommend the former - but, oh well - it's your system tongue):

# pacman -Syu && ~/.local/bin/updbar_rst.sh

*(Personally, I usually do the update while not being logged into a graphical environment, BUT if you must emulate the behavior of similar modules out there, I'll give you an inch: "on-click-middle" is unallocated by default... - please don't ask for a mile tongue)

# Development


Systemd user service:

CAVEATS: can potentially freeze the module if stopped while processing, but can be reset by a right-click.

Usage:
Place 'updatenotif.service' inside '~/.config/systemd/user/' (do not replace "user" with your own user here), replace "username" with your user in the "ExecStart" array, then enable the service:

systemctl --user enable updatenotif.service

Or, if no other instance of 'updatenotif.sh' is running, you can start the service right away:

systemctl --user enable --now updatenotif.service

updatenotif.service (experimental):

[Unit]
Description=Notifications for Arch Linux package updates

[Service]
Type=simple
RemainAfterExit=no
ExecStart=/home/username/.local/bin/updatenotif.sh

[Install]
WantedBy=default.target

For more detailed info, please see: https://wiki.archlinux.org/title/Systemd/User


pclinf.sh (advanced menu, template/incentive - can be envoked from the default menu by pressing 'Enter'):

#!/bin/bash
#
#
cat <<MOS

──────────────────────────────────────────────────────────────────────────────

This script depends on:

'foot' (server)
'fzf'
'w3m'
'wl-clipboard'

If you intend to replace the "default" menu with this script,
then put it inside '~/.local/bin/', and edit the module like so:

───
⁽¹⁾Having an overview of updates and their versions one click away helps me in maintaining a mostly bug-free system, given that I follow the developement of specific applications, check bug reports regularly, as well as do some reading on these forums.
This module is taylored to my own preferences/needs. If you try it and come to find it useful, too, then that's just a bonus and I'm happy to contribute something to the awesome open-source community. Thanks

Re: [ WAYBAR MODULE *EOL* ] Notifications for Arch Linux package updates

You shouldn't need to store an endless string of numbers in the temp file, just one would suffice (which simplifies all the head|tail work):

#!/bin/sh

UPD=/tmp/updates

cur=$(checkupdates | wc -l)
read prev 2>/dev/null <$UPD

[ $cur -le ${prev:-0} ] && exit
echo $cur >| $UPD

notify-send -t 10000 \
	--icon=/usr/share/icons/Papirus-Dark/48x48/apps/mx-updater.svg \
	"Updates:" "$cur"

Re: [ WAYBAR MODULE *EOL* ] Notifications for Arch Linux package updates

### Desktop notifications ###

This script is not actively maintained, but I'm happy to address possible issues,
it *should* also still work with 'chckpds.sh' (menu script) from post #1...

updatenotif.sh:

#!/bin/bash
#
#
### Description:
#
# Run this script at startup of your graphical
# environment. It will check for updates every
# 30 minutes.
#
### Dependencies:
#
# 'libnotify'
# 'pacman-contrib'
# 'fnott' (or a notification daemon of your choice),
# please also see: "https://wiki.archlinux.org/title/Desktop_notifications"
# 'fuzzel' (optional, menu feature)
# 'papirus-icon-theme' (optional)

Re: [ WAYBAR MODULE *EOL* ] Notifications for Arch Linux package updates

@dogknowsnx this didnt work for me. When i try to run chckpds.sh i get:

cat: /tmp/upd_versions: No such file or directory
./chckpds.sh: line 8: /tmp/upd_versions: No such file or directory

do i have to create these directories or should they be present by default?

If 'updatenotif.sh' is properly launched at startup of your graphical environment, both files will be created "by default" - '/tmp/upd_versions' won't be created unless there is a network connection - the script will retry fetching updates every 5 minutes.

Which DE/Window Manager are you running and how do you start 'updatenotif.sh'?

EDIT: If it's only 'chckpds.sh' that fails for you, there's a chance that you're running an older version of 'updatenotif.sh' and you would have updated partially - which is not supported on Arch tongue
Please also make sure to have read the notes at the bottom of post #1 before posting...

Well, there are already a couple of problems. First, you are stating two paths ('~/bin' and '~/.bin'), which one is in your $PATH? And second, for convenience (and to prevent issues like you're describing) I picked '~/.local/bin/' as the location where additional scripts will be looked for - $PATH is irrelevant in this use case. If you want to use $PATH, you can grep -n the code above for '~/.local/bin/' and remove that part and only leave the script's name in place (untested on my part and possibly error-prone, but *should* work). Or you can simply place the scripts inside '~/.local/bin/' and your issue *should* be solved...

EDIT: Third, looking over the scripts in your .dotfiles I can tell you that you're running a partial update - please replace the scripts by the ones from post #1.

EDIT#2: You may want to also check your waybar config, since there appear to be a few too many open brackets...

1) im sorry i accidentally wrote ~/.bin i meant ~/bin (~/bin has been added to $PATH using   PATH="$HOME/bin:$PATH")
2) does adding scripts to ~/.local/bin automatically adds the scripts to $PATH, if so that solves a lot of my problems
3)i see what you mean, i usually just add }, instead of } and then }, because it works. i will fix it and see if things change

2) No, you would have to export it e.g. in your shell's rc file

export PATH=$PATH:$HOME/.local/bin/

but that's a different issue.

I'd suggest you try the whole thing as is (and as is intended) without editions/customizations first and see if it's working for you. Then It'll be easier to troubleshoot (for me, but also for you).

OK so here's what i changed:

1) created .~/.local/bin and added all three scripts (updbar.sh, chckpds.sh, updatenotif.sh)
2) changed config module in waybar. changed hyprland.conf to exec ~/.local/bin/updatenotif.sh
3) restarted hyprland

the module does not show on my waybar but:

1) chckpds.sh opens fuzzel and shows updates
2) htop shows ./updatenotif.sh running
3) updbar.sh appends {"class":"new-updates","percentage": 100,"tooltip":"Updates: 12\n\n(on click: view updates)\n(right-click: refresh db)"}

2 things i wanted to clarify:

1) im using waybar-hypland-git package from aur(to display workspaces)
2) i have symlinked waybar from my git repo to ~/.config does that affect anything?

Re: [ WAYBAR MODULE *EOL* ] Notifications for Arch Linux package updates

As to the last two points: i honestly have no idea and currently won't be able to test this.

What does waybar report, if you start it from your terminal (wild guess: you are still using the wrong path(s) in your waybar config...)?

EDIT: Ok, I saw you've changed it to '~/.local/bin/' - what about those brackets, then? And did you try with a local config file for waybar?

Anyway,

Re: [ WAYBAR MODULE *EOL* ] Notifications for Arch Linux package updates

Please try this: copy the module from post #1 and add it on top of your other modules in your config - also did you try starting waybar from the terminal to see what it reports?
