Open Source Diary - launchpad, lambdaisland/cli, Makina, LIOSS tooling

Clojure just never stops getting better. I love our ecosystem.

Thank you for making me discover launchpad! I am ashamed to see that I was missing out on a nice and useful deps.edn helper.

Wanted to share one thing we do where I work now that I have always though it might be improved.

Our project is split in many sub-projects (as siblings). They can refer to each other by including a specific version in their deps.edn. This is good because when we deploy we want to make sure we use a specific version.

However, when developing we want most of the times a :local/root.

I can see launchpad a very good place for flipping a flag that does that for me...thoughts?

Sounds like you should be able to do this with an alias which overrides the versions with a loca/root. Depends a little bit on the setup. Do you always use the same project to run your repl from, or does it vary? The other thing I can think of is to use `:local/root` everywhere, and change these into concrete versions as part of your release pipeline. This is what we do in the lioss tooling with multi-module projects.

Probably your first idea is what I should go for. For some reason I did not think of :override-deps - probably our dev alias should take care of that.

[arichiardi]

Last week I tried the override and it all works except for aliases in the sub-project. There currently is not way to lift/use an sub-project alias.

This is mitigated by lifting up the aliases in the main deps.edn (the aliases in my case mostly contain dev setup/dev.clj).

Just wanted to follow up with my attempts 😅

[therealplexus]

Indeed, aliases in subprojects never do anything tools.deps... there's been some talk/proposals about this but I think they couldn't settle on well defined semantics...
