@ag no, there is no merging, the second require should overwrite the first

hey @rcanepa: when you make an uberjar, you are making something that does not use lein. So you'll need some other mechanism for configuration. One option is a command line parameter interface (https://github.com/clojure/tools.cli); another is environment variables or system properties (https://github.com/weavejester/environ), or perhaps either of those to specify the location of an edn configuration file (https://clojure.github.io/clojure/clojure.edn-api.html).

@firstclassfunc: Mark Derricutt is a good person to talk to about that

.oO(That’s a very small world. I was about to comment earlier today how #C0FCN8L1Y needs @talios. I should ping him to join.)

@danielcompton: Huh, you’re in Auckland too, eh? Nice. (I used to live in Auckland, and I know Mark IRL.)

Is @talios not on here? I’ll have to bend his ear about that.

When trying that in the REPL :

(require 'clojure.inspector)

(clojure.inspector/inspect-tree '(1 (a b) 2 (c d) 3 (e f )))

Ah nevermind they were hidden

@lmergen: Another possibility from earlier:

user=> (map (partial zipmap [:key :value]) {:name "Joe Awesome" :email ""})
({:key :name, :value "Joe Awesome"} {:key :email, :value "”})

ah that looks like a very clever solution

but it's just a little bit less intuitive what it does, i htink

otoh, zipmap is probably the best operation for this

what's a way I can make certain data structures print differently ? I'm sharing results with our team and it would be nice if things like vectors of keywords were printed as simple strings like xyz not [:x :y :x]

(sorry [:x :y :z]!)

I can't do by type, it needs to be by structure...maybe prismatic schema has something ?

maybe: apply str (map name [:x :y :z]))

?

returns "xyz" in this case

(parens missing, so:)

(apply str (map name [:x :y :z]))

@mmeix: ok, thanks but I was hoping for a more general solution

ah, ok

maybe with vector?and keyword?and so on?

i think Schema coercions/bijections & Fipp are the way to go

Can anyone tell me why lein test tries to run tests in the user namespace?

And lein test my.test-namespace fails with class not found, even though it is in the test/ dir

I have a user.clj inside a /dev folder, with the following leiningen config: :profiles {:dev {:source-paths ["dev"] :dependencies [[org.clojure/tools.namespace "0.2.11"]]}})

good afternoon people. Quick question: is it legal to (require ‘[some.long.namespace :as long.namespace]) ?

@jonahbenton: Thanks!… I will check those options.

IOW using dots in namespace aliases: yep! or oh no!?

@joost-diepenmaat yep yep!

@joost-diepenmaat: totally!

oh cool

that will make some code here a little bit nicer

@joost-diepenmaat: https://stuartsierra.com/2015/05/10/clojure-namespace-aliases is a good reading IMO, and it recommends using them

thanks @nberger for that link.

np

Can anyone point me to an open source project using the reloaded workflow with a route to deploy to production and run tests through leiningen? Having trouble working out how to make everything work.

@danielstockton: clojars uses the reloaded workflow, is deployed to production and has tests that run with lein test, so you could take a look there: https://github.com/clojars/clojars-web

Perfect example, thanks

Does lein need tests to be organized like test/proj/test and proj.test.namespace (two test directories)?

I generated this structure with lein new, but that's the only difference I can see.

lein test should use the :test profile right, so shouldn't pick up my :dev profile config like :init-ns user

Is it possible for codox to generate output from a deftype? Specifically, I have functions implementing a protocol inside the deftype and while it is valid clojure to add a doc string to each function, codox doesn't seem to pick it up. I don't think it makes sense to document only the protocol itself because the implementation details are where you actually want specific docs.

to be clear, I don't mean on the type definition, just the protocol implementation

@danielstockton: Glancing through https://github.com/technomancy/leiningen/blob/master/doc/PROFILES.md, I think that lein test merges in the test profile -- presumably into the dev profile. You should be able to disable the dev profile explicitly by lein with-profile -dev test.

Unfortunately it still tries to run the user namespace 😞

hi guys, does anyone use clojure with protocol buffer ? is this the right lib to use https://github.com/flatland/clojure-protobuf . I find it's a bit oudated

Is lein caching something somewhere, should I try clearing some files? I had init-ns set up globally to user before but it's now under the :dev profile.

You're sure you had this setting only in your project.clj and not in ~/.lein/profiles.clj?

Yep

xposting from #C077KDE3A: I'm having a db issue with a recent version of Luminus (I think), where trying to operate on a database is giving me this: 'IllegalArgumentException db-spec mount.core.DerefableState@6dc3d84b is missing a required parameter clojure.java.jdbc/get-connection (jdbc.clj:292)'

you are passing a derefable state to something that needs a connection or a connection spec

likely you forgot to deref the derefable state

the line number and fill will be somewhere in the stacktrace

@danielstockton: Clojure itself, not Leiningen, loads the user.clj file on startup.

This cannot be disabled.

what is the easiest way to rename an entire project? (files/dirs/namespaces/etc.) Possible?

I've had some success using this https://github.com/clojure/tools.namespace/blob/master/src/main/clojure/clojure/tools/namespace/move.clj#L86

I feel like I should also point out, that there are many orthogonal names used for clojure projects, so for example you can change the the maven coordinates (group-id, artifact-id) without touching namespaces at all

@hiredman: checking it out now... thanks...

that's interesting... I usually use sed

clojure allows more than is generally used in practice, what is generally used in practice has a regular structure that tools can exploit for this sort of thing, but having something that handles all valid clojure files is more complicated

@dm3 all good suggestions, sed might be easier for now, I'll give it a go

Ok guys gonna ask this here, Has anyone used Leiningan templates and tried to copy binary files like images?

Never mind.. Figured out you create a raw resource such as ' (def raw (raw-resourcer "brocade”))'

What seems like a better design, a huge namespace with a single deftype that wraps a Java object, and implements many protocols, vs. a few separate namespaces that are all passing in the same Java object? Alternatively, I suppose I could also use extend or extend-type depending on what I do. I've already split things up into some nice protocols and switching between the two is pretty much seamless. I don't think people will call this from Java that much, but it's a possibility (but i don't want to bother with gen-class).

I should mention that the code is fairly performance sensitive
