There are about 3 years of newer commits since 1.1.0, and one of the major changes is that it adds support of scala 3 syntax which is not yet in a tagged release and would be good to have. Also seeing the last commit is from the end of last year, I sense that upstream may becoming a bit dormant for the time being, which is why I prefer to package the latest snapshot instead of waiting for a stable release. > Also, do you use this package? > Not on a regular basis, but I do use it a bit once in a while as I try to learn a bit of new programming languages every few months. >>>> * Override clean rules in d/rules to fix building.

Oh yes it's generated using Cask following upstream practice. I just include it as a patch as we don't use Cask for Debian packaging. > Either make the changelog and patch description consistent with what > is actually happening, or change the implementation so that something > is actually generated (there are multiple approaches here).

Though arguably in this case the scala-mode-pkg.el file needs to be generated/patched which requires I use Cask locally, so it's more or less the same effort. And then I just realized: why not just host the scala-mode-pkg.el file and substitute the version so that we don't need to update it manually on each update?

Well I didn't choose it (if I did I'd use 1.1.0 :) This is the version specified in scala-mode.el[2]. > Did you verify that elpa package version is consistent with the > upstream version of the Debian package in bin:elpa-scala-mode that is > consumed by users (the binary package)? > I tried install it from stable.melpa.org and yeah it's being installed as scala-mode-0.23 even if it's registered as version 1.1.0 there[3]. So it's consistent in a sense :P Anyway, I have just made a pull request to update this upstream[4] so hopefully the versioning will be sane. >>>> * Modernize d/watch using special substitute strings. >>> >>> Ok, but why? >>> >> >> I believe this provides a more robust way of detecting tags and should >> be an encouraged practices.

On a related topic, I used to change the section from "lisp" to "editors" following lintian suggestions, but it seems you and Sean are not very keen on this. I'll try to start a thread on the mailing list for suggestions. >>>> * Use xz compression in d/gbp.conf. >>> >>> Why is this useful when it has been the default since gbp 0.9.15? >>> >> >> I'm pretty sure that if I don't add this "git deborig" will create the >> tarball using gzip instead. > > Really?

Yes, I meant "gbp" in this context. I think adding the options makes it consistent with "git deborig", otherwise we may get "more than one orig tarball is available" error (".tar.gz" from "gbp buildpackage" and ".tar.xz" from "git deborig"). > Meanwhile, compression type isn't the problem: > > gbp:info: Tarballs 'scala-mode-el_1.1.0+git20221025.5d7cf21.orig.tar.gz' > not found at '/home/sten/devel/tarballs/' > gbp:error: v1.1.0+git20221025.5d7cf21 is not a valid treeish > This is because I didn't push the tag to the repo yet.

For the aspect of the consistency with upstream release tarball, I'm trying to understand how to make this work. I believe "gbp import-orig --uscan" should grab the upstream release tarball which follows your suggestion. However IIUC the repository is configure using the dgit-maint-merge workflow that uses upstream branch to target upstream repo and hence uses the tagged version to generate upstream tarball, which I believe is incompatible with "gbp import-orig --uscan" approach which directly import the release tarball without the git history. I wonder whether there is a way for "git deborig" or "gbp buildpackage" to grab upstream tarball automatically? I'm guessing not, so someone has to do it manually, but please let me know if there is a way. > Regards, > Nicholas > [1] https://salsa.debian.org/emacsen-team/scala-mode-el/-/commit/fcb6d233254a2551957a71e37610b6cdd73824c4 [2] https://github.com/hvesalai/emacs-scala-mode/blob/master/scala-mode.el#L7 [3] https://stable.melpa.org/#/scala-mode [4] https://github.com/hvesalai/emacs-scala-mode/pull/183 [5] https://salsa.debian.org/emacsen-team/scala-mode-el/-/commit/7a7947b25fa9a2e9352927b15444443b19e40f72 -- Xiyue Deng
