Launching things in parallel is usually done using this pattern: https://github.com/nextjournal/clerk/blob/f7644767ae6fbcb4b05a432ea7b554fbe9e0464c/bb.edn#L101-L103

very handy! it's the primary thing i'm doing between targets

thanks for the link

can i get an honest objective-as-possible opinion if it is a good idea to migrate away from Make? It's either gonna be stay on Make, move to bb task runner, or just https://github.com/casey/just

i know you're biased, but give it a shot 😉

Well, I wrote babashka tasks as the Clojure answer to Make :)

You get all the expressivity of Clojure , so you don't even have to use the features of the task runner, but can just write a couple of functions and call those from the task runner

what about comparing this to just? it looks spot on to this kind of thing. only disadvantage is that it's on rust. not a really important reason since i'm only using it and not developing anything

I would say read the documentation at https://book.babashka.org/#tasks or watch my talk on it and then make your own judgements

Make and Just are fine, but I like Clojure

👍

thanks

(i've read that before coming here, was still contemplating)

Of course there's other people in this channel too, so I'll let them reply here for less biased opinions ;)

My 2c: yes, you can even use Make for that, but Compose has a couple of features that you won't get easily with just bb + Docker: health checks, dependent services, networking that actually semi-works on macOS. Nothing is stopping you to use bb tasks to call Compose, but you might find yourself reinventing half of what it does (speaking from my experience, I tried to do exactly that some time ago)

@U3RGL6XNF bb only supports a preselection of Java classes and can't run any other Java classes - so it's more limited than Clojure JVM

Ahhh that explains it. Thanks.

I see that here now: https://book.babashka.org/#differences-with-clojure

Hi 🙂 What's your motivation for using bb? Faster startup? Something else? Lots (all? most?) of babashka's nicities (babashka fs, babashka tasks, babashka cli) can be used from JVM Clojure. For example, it's possible to use babashka/cli for CLI argument parsing in a JVM application. bb tasks can easily dispatch to JVM Clojure functions, utilizing babashka/cli to turn bb mytask :message hello into (com.myns/myfunc {:message "hello"})

@U3X7174KS Hi! And thanks for asking. Actually, I had just written a tiny script to do a simple data task for work and since my team doesn’t use Clojure I was trying to sneak it in and make it very easy to run. I’m so inexperienced with actually making Clojure usable ’cause I never get to use it for work so I wasn’t sure what to do. I was hoping to just be able to allow them to run a single command without doing much install and without modifying the code to use a main function.

So basically I have a directory with a deps.edn and then a script src/main.clj . main.clj loads a csv from disk and then processes it. I just want to make it runnable in the easiest possible way.

I guess I may just be able to use clj -X src/main.clj

In that case, clj -X seems like a good option :) It's also possible to have a single clojure file that uses dependencies. Here's an example: https://stackoverflow.com/a/52433251

@U0E2268BY Check out https://github.com/grzm/awyeah-api which is a re-make of cognitect aws-api for bb

ah nice!

or should I say ….
