You can't -> into an anonymous function like that. But you could use as-> instead.

(-> {:base-url “”}
      (as-> hash-map (assoc hash-map :abs-url (str (:base-url hash-map) “test2”))))

figured out how to make a recursive function that emits a result, it's like a whole new world

most of the examples are like "print the fibonacci sequence". Thanks, I'll just use google.

@notanon interestingly, I just saw this in #clojure - import-vars is exactly what I mean.

@pwalsh if your project is the size of an entire programming language + batteries included standard library, i'd agree, splitting up your ns might be acceptable 😛 😛

honestly though... looking at how clojure.core does it... it's not as if it's very complicated/hacky. up to you 🙂

http://stackoverflow.com/questions/4690758/splitting-a-clojure-namespace-over-multiple-files

you're looking at the unbelievable power of lisp's never ending eval < - > apply loop.

it's up to you how you organize your code. how you feed strings into eval is up to you.

you arent limited by the language (like java with classes)

or dependent on the language to support it (like c# with multi-file classes)

slightly off topic, but i remember watching a presentation from a guy that writes clojure for oil-mining machinery. he just (load ...)'s code from a http url to update the programs in place. just so awesome. and nasa debugging some c++ code on an orbiting satellite via a freakin lisp space repl lol.

@notanon (for [x test] {((wcar* (car/get x)) :username) (wcar* (car/get x))})

I got this ({"admin" {:username "admin", :password "pass", :roles #{:slckfu.handler/admin}}} {"admin2" {:username "admin2", :password "pass", :roles #{:slckfu.handler/admin}}} {"admin" {:username "admin", :password "$2a$10$byP7iTHiHGfrQSf0A/j9ruzFwsEfImweCSaZU45/Zudc2wbauhY/i", :roles #{:slckfu.handler/admin}}})

what I need to get: {"admin" {:username "admin" :password (creds/hash-bcrypt "pass") :roles #{::admin}} "dave" {:username "dave" :password (creds/hash-bcrypt "pass") :roles #{::user}}}

what means () around the result, that is a ... or?

As I see.. that is clojure.lang.LazySeq

I would like to find similar solution like this (into #{} [1 2 3 4]) ==> #{1 2 3 4}

lazy list to map

@sb please always try to format the code. Makes is easier to read

sorry!

@rauh I have the result in lazy seq, that is my problem.

@sb why not (wcar* (apply car/mget test)) and then transform the datastructure from there

But to answer your question: Just do a (into {} (for [...] [key val])

thanks!

Yes, that is really cool: (wcar* (apply car/mget test)) but unfortunately friend use the datastructure what I shared with you. You query result: [{:username "admin", :password "pass", :roles #{:slckfu.handler/admin}} {:username "admin2", :password "pass", :roles #{:slckfu.handler/admin}} {:username "admin", :password "$2a$10$byP7iTHiHGfrQSf0A/j9ruzFwsEfImweCSaZU45/Zudc2wbauhY/i", :roles #{:slckfu.handler/admin}}]

I need to drop plus “user” field before this.. if I understand good the docs

You mean :username keys?

yes

(mapv #(dissoc % :username) res0

Ok, I test it. One moment.

Thanks!!

Works!! 👍👍 Thanks for your help!!

@rauh

Hello, Sorry, I have a new question..

I try to generate jars with that redis connection

but I got error messages.. do you have idea how can I fix it?

I think, that is a wrong embed profile setup.. but I didn’t find a good tutorial about.

(redis/carmine case)

if I add to the dependencies No value supplied for key: [com.taoensso/carmine “2.15.0”] I got this error messages. I tried add value for keys with :env {:redis-host "127.0.0.1" :redis-port 6381}

so if have any idea, welcome 🙂

If I comment this lines ` (def testuser (-> (wcar* (car/keys "admin")))) ;(def users (into {} (for [x testuser] {((wcar* (car/get x)) :username) (wcar* (car/get x))})))` of course everything works fine.. at uberjar flow.. so that is something connection problem.

How do I telll that name is a string with spec . I tried this : (s/def ::frontpage-name(string?))

but then I see a arity error

or is Cursive mistaken ?

@roelof why is string? being called with no arguments there?

I don't know spec, but that looks super weird

the lack of space before the ( makes it look like you are trying to write java

I want to test if the keyword :name can only have a string as contents

but you are giving two arguments to def

one is a namespaced keyword, the other is (string?) which is the function string? called with no args

which is an error

yes, the name of the condition and the condition itself

what I am saying is that condition is an invalid arity error

(string?) is an error

yes, that is why I said earlier

that is also the message that I see also

why are you putting parens around it?

that's what causes the error

but I do not know how to tell spec that the keyword :name must contain a string

@noisesmith thanks, that seems to solve it

@roelof do you understand why I could see it was an error even though I don't know spec? in clojure we don't use parens for grouping (except for a few very rare cases that you can count on one hand) - they are for calling functions

yep, thanks

if I were to redo the clojure syntax (or make my own clojure-like) one of the only changes I would make is not using parens on the left side of case clauses (just to reduce that ambiguity - to never have parens as grouping constructs)

hello all, I´m trying to understand specter, so how to select the keys with false values?

(select [ALL <???>] #{{:RES false} {:TAM true} {:ITA true}})

fabrao: did you try false? ?

oh, you need the nested structure, so it would be more like (comp false? val) wouldn't it...

yes

I did like this

(->>  #{{:RES false} {:TAM true} {:ITA true}}
       (filter #(= true (second (first %))))
       (map #(key (first %))))

It seems to be more easy in specter, but I don´t know how to migrate from this to that

fabrao: maybe (comp false? val first) - that would get the first (only) entry in the map, check if the value is false in the entry

(select [ALL (comp false? val first)] #{{:RES false} {:TAM true} {:ITA true}})

@roelof i think you mean (s/def ::frontpage-name string?)

you dont want to invoke string?, you want to pass the function string? as the second argument to s/def
