Breaks rails generate. Rails 7 compat?

[pboling]

I am using service_actor-rails which provides an actor generator, and when I try to use it, while having this slim-rails gem installed, it blows up inside slim-rails. It appears to be incompatible with Rails v7?

rails generate actor do_something

slim-rails is compatible with Rails 7. In your case it looks like you are using a very old version of slim: gems/slim-0.6.1/lib/slim/rails.rb , 0.6.1 , please make sure you're using the most recent versions of both slim-rails and slim gems.

[pboling]

For both I did bundle add slim and bundle add slim-rails, and these were the versions I got. I am on Rails 7.0.4 and Ruby 3.1.3. I don't understand why it would give me an old version. Looking into it.

slim-rails  0.1.2    3.5.1    ~> 0.1.2   default

SO strange.

OK, I removed the constraints that were added by bundle add, and did a generic bundle update, and got the following:

...
Installing temple 0.8.2 (was 0.9.1)
...
Fetching slim 4.1.0 (was 0.6.1)
Installing slim 4.1.0 (was 0.6.1)
Fetching slim-rails 3.5.1 (was 0.1.2)
Installing slim-rails 3.5.1 (was 0.1.2)
Bundle updated!

I think the version of temple in my Gemfile.lock that was pre-existing had already eclipsed the older version that slim requires, and so it installed a version of slim so old that it predated the specific version requirement on temple. An oddity of higher specificity. 😆

Are there plans to loosen the temple restriction, or is it necessary?

s.add_runtime_dependency('temple', ['>= 0.7.6', '!= 0.9.0'])

[pboling]

It is also strange that != 0.9.0 disallowed 0.9.1... Is that expected behavior from bundler? My impression has been that != was to skip specific versions within an interval of otherwise compatible versions... which would mean it should accept 0.9.1...

[pboling]

Or maybe the latest master hasn't been released. When I add a discrete temple to my Gemfile:

gem 'temple', '~> 0.9.1'

I get:

Bundler could not find compatible versions for gem "temple":
  In Gemfile:
    temple (~> 0.9.1)

    slim (~> 4.1) was resolved to 4.1.0, which depends on
      temple (>= 0.7.6, < 0.9)

If that's true then the latest release from 2020-05-08 is unusable for a specific scenario of Bundler + temple. It looks like the change to support temple v0.9.1 was made on 2022-10-25, so perhaps a new release is forthcoming?

But... that's not even this repo...

For now I'm pointing my Gemfile to git for slim. 👯
