Posix: use /etc/dub/settings.json if in /usr

[WebFreak001]

Fix #1472

/etc/dub/settings.json overrides /usr/etc/dub/settings.json (as
suggested by the man hier manpage)

[WebFreak001]

another idea would be to have /etc/dub.conf which could be considered better than /etc/dub/settings.json because dub only has a single config file (and probably won't get much more that belongs in /etc)

[Geod24]

Yeah I think /etc/dub.json is better

[PetarKirov]

I think /etc/dub.json is better

I disagree. dub.json sounds just like dub.sdl - package metadata. Here we're talking about (global) configuration of the dub program itself. If people find it strange that dub.conf is a JSON file, then I suggest dub.config.json.

[WebFreak001]

I would suggest dub.conf - maybe it should be a SDL file too though

[WebFreak001]

I asked on the discord and got these preferences by users: (mostly weak preferences)

• /etc/dub/settings.json (Wild, Snarwin, MoonlightSentinel) - Reasons:
  • consistency with the existing ~/.dub/settings.json
  • If dub ever needs an additional file for something, already having a folder make that easier (x2)
  • Wild: I generally think of /etc/*.* of being more system configs, while /etc/*/*.* is more program configs. But ofc there are always outlieers
• /etc/dub.conf (WebFreak) - Reasons:
  • consistency with a lot of other linux package config files

adr doesn't really care but after asking about /etc/dub/settings.json thinks it's good enough for him, it would be easy to find as /etc/dub will find it anyway.

So I would be for putting it in /etc/dub/settings.json as final decision to avoid stretching this bikeshed for longer.

The reasons that most influenced me on this decision: (in this order)

• consistency with existing ~/.dub/settings.json
• /etc/dub.json would be confusing with dub recipe filename, /etc/dub.conf might not be obviously json and /etc/dub.json.conf is not much nicer
• a lot of (modern) linux apps use folders as well, it's convenient for the user to store more than one settings file in there which they can swap out as needed

I do like dub.conf.json/dub.conf.sdl, but yes let's just go with /etc/dub/settings.json.

This does need documenting though.

[WebFreak001]

@rikkimax added changelog entry and made PR to dub-docs (though I doubt that PRs there will be merged any time soon with deployment being broken)

[PetarKirov]

I'm on board with /etc/dub/settings.json as well.

[WebFreak001]

can someone approve the PR so I can merge it?

Moving towards the XDG standard is preferable tho. ~/.dub/settings.json is not XDG compliant. See https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html .

[WebFreak001]

~/.dub/settings.json has already been used and is not touched by this PR, I would suggest talking about that in a separate issue or e.g. plan that for a second version of dub.

I think how I PRd it here is best for how the current structure is.

So if anyone could approve the PR that would be nice.

Right, my bad.

[ljmf00]

I agree with the change, but I'm not part of dub development and I may miss something, although LGTM.

[WebFreak001]

ok seems like I would need someone of the dub team to approve to be able to merge
