I'd actually suggest to do so. Just had to reinstall my OS and had to mod the PKGBUILD again because of checksum failure.

OK, I just updated my version, but I'm also vaguely tempted to just "claim" that this is a "VCS"-like package because the pkgbuild now basically works for all versions (except for moving pkgver to a pkgver() function, and changing the hashsum to SKIP)...

Yup that works for me. I actually just saw that I forgot to escape my dots. Assuming that the way they version their products stays the same (e.g. the don't start putting dashes and stuff). However I expect my grep search to be quicker, and also it requires no extra call to tail :P

Looking at it again, I guess the following would be even simpler:

_dlurl="https://www.snapgene.com/local/targets/viewer_download.php?os=linux_rpm&majorRelease=latest&minorRelease=latest"
source=("$(curl --silent --head --location "$_dlurl" | grep -Po 'Location: \K.*rpm' | tail -n1 )")
pkgver="$(grep -Po '\d(\d|\.)+\d' <<< "$source" | tail -n1)"

Can you confirm it works for you?

I guess curl changed its output format?

Probably, I don't use it often enough to notice.

Also I think the old pkgver grep was more robust, as it would allow version numbers such as x.y.zz? (4.3.11 did exist)

Mine should allow for that as well. Even filenames such as "snapgene_viewer_stable_26.5.5846_linux.rpm" should be fine. The hash is more of a inconvenience imo.

It's just changing a few commands for setting the variables:

_filename=$(curl --silent --head --location "$_dlurl" | grep -Po 'Location: https://.*\K(snapgene_viewer_.*_linux.rpm)' | tail -n1)
pkgver="$(grep -Po '\d+.\d+.\d+' <<< "$_filename")"                              
source=("$_filename::$_dlurl")                                                   
sha512sums=('bf1f3e2c144e42e40484bc9d7c14440421634a34b39dbcd7f6a4cbdc084decae8f9bdb6ec807f6cffa46842088065bbcb224d13a8baaad3fbd963d2b6e9cbecd')

I guess shasum will change on each patch though, so that might need to be readjusted from time to time.

feel free to post a patch here or link a gist.

@jfaccioni @mollitz @anntzer I managed to make a running PKGBUILD, is there some way to make a PR so that it can be incorporated into AUR?

Build still fails due to incorrect sha512sum. Manually fixing the sha512sum by editing PKGBUILD results in a successful build, but the program does not launch.
