Each run saves the pending repo, AUR and kernel updates to $XDG_STATE_HOME/update-notify/pending, independent of the threshold, so a status bar can show them and drop the ones installed since.

# update-notify
|
|
|
|
Desktop notifications for pending updates on Arch Linux.
|
|
|
|
update-notify runs on a systemd user timer and checks:
|
|
|
|
- **Repo updates**, using `checkupdates` from pacman-contrib.
|
|
- **AUR updates** for packages in a local aurutils repository (`aur repo -u`).
|
|
- **Custom kernel rebuilds**: when a stock kernel (e.g. `linux-lts`) has a newer version than your custom build of it (e.g. `linux-lts-custom`).
|
|
|
|
It sends one notification, and only when its content changes since the last one:
|
|
|
|
- Update counts are shown once the total number of updates reaches a threshold (default 30). Reminders for `git-monitor` and pending firmware updates (`fwupdmgr`) are added when those tools are installed.
|
|
- Kernel rebuild reminders are always shown, even below the threshold.
|
|
|
|
## Requirements
|
|
|
|
- `pacman-contrib`
|
|
- `libnotify` and a running notification daemon
|
|
|
|
Optional:
|
|
|
|
- `aurutils`: check AUR packages in the local repository
|
|
- `fwupd`: check for firmware updates
|
|
- `git-monitor`: remind to check git packages
|
|
|
|
## Installation
|
|
|
|
Build and install the package with the included PKGBUILD:
|
|
|
|
```
|
|
makepkg -si
|
|
```
|
|
|
|
Or, with aurutils, build it into your local repository with `aur build` and install it with pacman.
|
|
|
|
Then enable the timer:
|
|
|
|
```
|
|
systemctl --user enable --now update-notify.timer
|
|
```
|
|
|
|
The timer runs 5 minutes after boot, then every 6 hours.
|
|
|
|
## Usage
|
|
|
|
```
|
|
update-notify [threshold]
|
|
```
|
|
|
|
`threshold` is the minimum number of updates (repo + AUR) before update counts are shown. It overrides the `THRESHOLD` setting below.
|
|
|
|
## Configuration
|
|
|
|
Settings are read from `$XDG_CONFIG_HOME/update-notify/config` (default `~/.config/update-notify/config`), a bash file that is sourced by the script. All settings are optional:
|
|
|
|
- `THRESHOLD`: minimum number of updates before update counts are shown (default 30).
|
|
- `AUR_REPO`: name of the local aurutils repository (default `aur-local`).
|
|
- `KERNELS`: maps each stock kernel package to its custom build (default: `linux`, `linux-lts` and `linux-zen` to `<name>-custom`). Kernels where either package isn't installed are skipped. Set `KERNELS=()` to disable the kernel check.
|
|
|
|
A commented sample config is installed with the package. To start from it:
|
|
|
|
```
|
|
mkdir -p ~/.config/update-notify
|
|
cp /usr/share/doc/update-notify/config.example ~/.config/update-notify/config
|
|
```
|
|
|
|
Kernel versions are compared without `pkgrel`, so a stock packaging-only update doesn't trigger a rebuild reminder. A custom build already in the local repository but not installed yet counts as up to date.
|
|
|
|
The content of the last notification is stored in `$XDG_STATE_HOME/update-notify` (default `~/.local/state/update-notify`). Delete it to get the current notification again.
|
|
|
|
## Status bars
|
|
|
|
Each run also writes the pending updates to `$XDG_STATE_HOME/update-notify/pending`, whether or not the threshold is reached, for status bars such as xmobar to read:
|
|
|
|
```
|
|
threshold 30
|
|
repo <pkg> <newver>
|
|
aur <pkg> <newver>
|
|
kernel <custom-pkg> <stock-ver>
|
|
```
|
|
|
|
The file reflects the last run. To keep a bar current after an upgrade, drop entries whose installed version (`pacman -Q`) is no longer older than `newver`, or, for `kernel` lines, whose custom build has caught up with `stock-ver` (ignoring `pkgrel`). This only reads local data, so it's cheap to run often.
