Any reason why running -main from the repl would behave differently than running from the jar given that the project’s :main is that -main’s namespace?

@puhrez: Different compilation settings? Different settings in dev profile than in uberjar profile? Different application configuration used?

hmmm

There are a lot of possibilities, it is hard to guess whats going on without specific errors or whatever is going wrong for you

ya i know rather general, but from there we can drill down!

its like, my -main maps over a set of messages publishing each to a notification service (AWS SNS), but it doesn’t seem like it’s mapping at all during jar execution

i put a println in there and nada

ya i don’t have any different profiles in my project.clj or my profiles.clj that would affect compilation

Hm, my project.clj and main clj file look like these:

hmm the only different i’ve found between this project adn others is that :aot :all

i will lookinto that omit-source tho

Hm, I dont think the :omit-source is important here, just left it in there for completeness. Good luck

😢

Do you build an uberjar or just a jar file?

uberjar

hmm, also just noticed that i didn’t get a compilation error despite only of my dependencies not being the project.clj...

did you run a lein cleanalready?

yup

and i don’t have auto clean on

so it would’ve done that before uberjarring

Hm, strange

yup

hmm i found the issue

have a println form after my map seems to skip over the map...

is this a thing or am i just doing stupid stuff?

(let [my-set (get-set input)]
(println "doing blah to" (count my-set) "things")
(map blah my-set)  (println "Done"))

(sorry for the shitty formatting) but basically with that last println the map was being skipped over

@puhrez: map is lazy and will not evaluate until you force it to in some or the other way

ahhhhh

that’s why it works when i put a call to count before the final println

Also REPL calls evaluate map IIRC

well im really glad it was something fundamental like that pshh

I often fell into this trap too 😄

@sveri: thank u very much for ur help

No problem, you'r welcome

What is the best way to get started with Clojure?

It depends: I’d say that Living Clojure (http://shop.oreilly.com/product/0636920034292.do) is a really good book for beginners.

https://notamonadtutorial.com/how-to-earn-your-clojure-white-belt-7e7db68a71e5 was incredibly helpful for me

I also found quite interesting the interactive implementation of Game of Life in Clojure: https://github.com/kolman/GoL-Clojure - definitely not a tutorial but it’s really cool to see Clojure in action

Any practical tutorial ?

@abhishekamralkar: did you look at http://www.braveclojure.com/?

Yes I am reading it

@abhishekamralkar: https://github.com/functional-koans/clojure-koans this is useful for practice

Oh okay. I think there’s a book called “Clojure Applied” or something like that. It’s not aimed at complete beginners I guess

Okay Thanks!

Also I was thinking to start with small project in Clojure so that I can use it scratch my head thinking like Clojurian.

oh!

the wonderland katas are great for that

This is Great!

ya and super fun!

Cool. Thanks for sharing.

have any of you used meteor with clojurescript?
