[ WAYBAR MODULE v4.0.3 ] Notifications for Arch Linux package updates

dogknowsnx · 2022-09-07 14:17:51

DISCLAIMER:
This module requires waybar >= 0.9.24 ! (see also upstream issue (fixed): https://github.com/Alexays/Waybar/issues/2631 )

NOTE: If you came here by clicking on the link in my signature and expected to find desktop notifications, please have a look at post #3

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
#
#[v4.0.3]
#
# 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):

Animated notifications:

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 :

(The update count can either be hidden or shown (new default) on the bar - see "format" examples inside the module)

Menu feature (fuzzel):

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:

Placeholders used in the module:

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 ):

# 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 )

# 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:

		"on-click": "footclient -w 1800x1000 ~/.local/bin/pclinf.sh",

Script that checks for updates of this module as well as for the 'RI module' (if you're using this, make sure to bump the version number found at the top of 'updatenotif.sh' (and 'ri.sh' if using 'RI') after you updated in order for this to work - basically do the update according to the changelog...):

#!/bin/sh
#
#
# If you intend to integrate this script in the module,
# name it e.g. 'updatenotif_upd.sh', place it inside 
# '~/.local/bin/' and add:
#
#		"on-click-middle": "~/.local/bin/updatenotif_upd.sh",
#
# to the 'on-click-*' arrays inside the module.
# The method above requires working desktop notifications
# and 'libnotify'.
# Otherwise just run the script from your terminal.

───
⁽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

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

### 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)

@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
Please also make sure to have read the notes at the bottom of post #1 before posting...

Ok i use hyprland i have placed updatenotif.sh in ~/.bin ( which is added to $PATH)

i added the line exec-once = ~/bin/updatenotif.sh & in hyprland.conf

https://github.com/arnavgr/dotfiles/tre … fig/waybar is where i have it setup. If theres anything wrong that im doing please help me

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?

dogknowsnx · 2023-05-02 14:59:39

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,

i dont know what you mean by those brackets, can u elabolarte. btw thank you for helping me

dogknowsnx · 2023-05-02 16:10:02

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?

Edited...
