It is a follow-up for discussion in pacman-dev

One thing that can be improved in Arch project is how out-of-date packages are discovered. Currently it is done by users who go to find the package and then click "Flag Package Out-of-Date" link. Why to bother users? Why not to let some bot to visit websites and check for new versions?

There are examples of package managers that have such functionality - macports Their Portfiles can have information about how to find released files (using regexp). Then periodically (e.g. daily) a bot visits webpages, parses html and checks if new files are present.
This task depends upon

In theory the bot can use "source" field of PKGBUILD. e.g. source looks like


It can extract the archive url$pkgname/$pkgname-$pkgver.src.tar.gz

and then try to probe newer $pkgver. e.g. current $pkgver is XX.YY.ZZ so it can try XX.YY.ZZ+1, XX.YY+1.0, XX+1.0.0 it should cover most project upgrades. There are some cases when version is not numeric one e.g. includes -alpha, -beta -rc, or some other versioning.

Hi, I have a script that checks versions. It is almost done and I'll send one to arch-general in a few days.

Hi, Dan.

Do you need any help with the task? I implemented the pkglivecheck script and I can share experience and thought with you.

I think to implement this task we need 3 things:

1) A ./ script in makepkg or some other standard package. The script will be run by TU to find out-of-date packages. It is similar to my *.rb script but should be probably rewritten as it seems that shell is the standard language for tools in Arch.

2) By default livecheck script should use the algorithm described above. But there are a plenty of packages that do not follow the release version numbering. See for more info. We need to add some a special field/function to such PKGBUILD that will describe how to find current released version. Something like

livecheck() {
curl -s | grep -Po "The current released version is less-(\d+)" | grep -Po "\d+"

it will parse home page for 'less' project and extract current version. If it does not match version in PKGBUILD then some warning is printed.

3) Write a cron job that will run ./ periodically and marks packages out-of-date on archweb.

What do you think?

Repology, and nvchecker and urlwatch are all options for OOD notifications.
