When installed as a "tool", could the SLF4J annoyance be taken care of automatically?

Clojure describes tools as:

The Clojure CLI supports the idea of running tools, which are programs that don’t use the project classpath, with the -T exec option. Tools are often (but not exclusively) external, defined with their own dependencies.

So could the antq "tool" be changed to automatically have the org.slf4j/slf4j-nop dependency, without affecting the user's projects?

@frou I've been looking for the way to avoid annoying message, but haven't found it yet.

As a "library", I don't want to have org.slf4j/slf4j-nop by default, because it effets user side project.

As a "tool", I want to have org.slf4j/slf4j-nop, but currently I cannot specify which aliases to use when installing as "tool".

• https://github.com/liquidz/antq/blob/e459ce567edb20ecb3d28f6e2a9df48b3e6a4acb/deps.edn#L13-L14
• https://github.com/liquidz/antq/blob/e459ce567edb20ecb3d28f6e2a9df48b3e6a4acb/deps.edn#L26-L27

For "tool", I can create another repository which provides both of antq and slf4j-nop, but I don't want to do this as much as possible because of the extra operational costs.

So If Clojure CLI supports specifying aliases for tool installation, I'd like to deal with it then.

If you have any ideas, PR is very welcomed!

Thank you for the explanation. I suspected that maybe a 2nd repository would be required, and I agree that's too much hassle!

Quoting Alex Miller from https://clojurians.slack.com/archives/C6QH853H8/p1668698984902689:

At the moment, you would need some kind of wrapper for the tool. You could either put that in a separate repo or put it in a subdir and use a git dep with a deps root and a local dep back to the root. I think that should work

You can add :deps/root to point to a subdir of a git dep

Sounds promising.

@p-himik Thanks for your information!

A partial solution.

Create an alias in ~/.clojure/deps.edn:

  :slf4j-nop {:extra-deps {org.slf4j/slf4j-nop {:mvn/version "2.0.16"}}}

Then invoke as:

clj -A:slf4j-nop -Tantq outdated

[hlship]

Or:

clj -Sdeps '{:aliases {:noop {:extra-deps {org.slf4j/slf4j-nop {:mvn/version "2.0.16"}}}}}' -A:noop -Tantq outdated
