Automatically update sha256sums

[smartshogu]

Hello Martin Dvorak,

here is an idea for an enhancement. If you download hstr directly from github and try to build it you get a validation error:

==> Validating source files with sha256sums... hstr-1.27.tar.gz ... FAILED ==> ERROR: One or more files did not pass the validity check!

Although editing PKGBUILD is not a big deal it does not work for everyone. So it would be nice to have the the sha256sums=(xxx) in PKGBUILD automatically updated after every commit.

Thanks for your work.

@smartshogu Thank you! I was not aware of that.

• stuck on inability to install Pacman's makepkg on Ubuntu

mg() {
        if [ ! -f ./PKGBUILD ]; then
                echo "No PKGBUILD in `pwd`"
                return 1
        fi

        local sums
        # calculate new md5sums
        sums=$(makepkg -g)
        # replace them in-place
        sed -i "s/^md5sums=.*/%NEWSUMS%/;/'[a-z0-9]\{32\}'/d;s/%NEWSUMS%/$sums/" PKGBUILD
        echo "PKGBUILD updated"
}
