Arch Linux User Repository

@TrialnError feel free to push your patch to AUR. I added you as a co-maintainer.

IIRC the git variant also needed some adjustment.
Following is a patch to make this PKGBUILD work again.
Several issues come together with the project structure of the 7.5.0 release which makes the normal workaround non-functional. Solution to that: Backport three upstream changes as patches

-  go get -u github.com/mattn/go-sqlite3
-
-  echo "Now getting go-fuse..."
-  go get -u github.com/hanwen/go-fuse/fuse
-
   cd "$srcdir/TMSU-$pkgver"
   make
 }

Edit: Only noticing it now. The provides line should also be removed. And fuse be changed to fuse2

There is a package tmsu-git, use it if this one doesn't work.

Another problem is that latest release (0.7.5) is from 2019 and doesn't seem to build on current Arch. The master branch works though. Here is PKGBUILD that I used:

  cd "$srcdir/TMSU-$pkgver"
  make
}

package() {
  mkdir -p "$pkgdir/usr/bin" \
           "$pkgdir/usr/bin" \
           "$pkgdir/usr/share/man/man1" \

  cd "$srcdir/TMSU-$pkgver"
  make DESTDIR="$pkgdir/" \
  MOUNT_INSTALL_DIR="$pkgdir/usr/bin" \
  install
}

I'll be happy to add you as co-maintainer if you provide a patch.

Is there a reason why the below presented workaround is not added to the PKGBUILD of this repo?

Regarding the missing files for Go modules see the following from Go package guildelines: https://wiki.archlinux.org/title/Go_package_guidelines#Upstream_project_without_go_modules

In short add the mentioned prepare function and remove the go get-commands from build.

go get is no longer supported.

==> Starting build()... Now getting go-sqlite3... go: go.mod file not found in current directory or any parent directory. 'go get' is no longer supported outside a module. To build and install a command, use 'go install' with a version, like 'go install example.com/cmd@latest' For more information, see https://golang.org/doc/go-get-install-deprecation or run 'go help get' or 'go help install'. ==> ERROR: A failure occurred in build(). Aborting... -> error making: tmsu

I don't know much about go build system, could you please bump the issue/PR upstream so they merge that fix? It would be a better solution, but in the end I could just patch it here.

the installation was dying on me with no required module provides package github.com/oniony/TMSU: go.mod file not found in current directory or any parent directory until i ran go env -w GO111MODULE=auto as per https://github.com/oniony/TMSU/issues/224
