I’m having some problems with working out why I have a lazy seq

(defn map-rewrites [rewrite-rules] (doall (map (fn [[k v]] (doall (str ".addRewriteRule(\"" k "\", \"" v "\")"))) (doall (seq rewrite-rules)))))
(defn map-matches [match-rules] (doall (map (fn [[k v]] (doall (str ".addMatchRule(\"" k "\", \"" v "\")"))) (doall (seq match-rules)))))
(defn map-remapping [{:keys [match rewrite]}] (doall (str "remapping(remappingBuilder.reset()\n" (doall (map-matches match)) (doall (map-rewrites rewrite)) ");")))
(doall (map println (map map-remapping remappings)))

[{:match {:api_key "doubleclick", :google_error nil}, :rewrite {:partner_user_id nil, :id_space "d”}}]

remapping(remappingBuilder.reset()
[email protected]@4da99836);

@dexter: I don't think doall actually converts things from a lazy-seq

user=> (type (doall (lazy-seq [1 2 3])))
clojure.lang.LazySeq

However, it should be printing out all of the relevant lines

I'd get rid of all doalls but the last one (map println)

its definitely not printing anything out

I’ve discovered why I think though

the map-matches and map-rewrites functions both actually return lists of strings

if I switch map to mapcat it gets fractionally further, materialising all the strings as a huge list of single chars

but then as soon as I try to concat them into a string it goes back to being lazy

Can you post the code with the doalls removed?

sure

Also, instead of mapcat, try

(flatten (map f col))

(defn map-rewrites [rewrite-rules] (map (fn [[k v]] (str ".addRewriteRule(\"" k "\", \"" v "\")")) (seq rewrite-rules)))
(defn map-matches [match-rules] (map (fn [[k v]] (str ".addMatchRule(\"" k "\", \"" v "\")")) (seq match-rules)))
(defn map-remapping [{:keys [match rewrite]}] (str "remapping(remappingBuilder.reset()\n" (map-matches match) (map-rewrites rewrite) ");"))
(map println (map map-remapping remappings))

Do you have example remappings?

[{:match {:api_key "doubleclick", :google_error nil}, :rewrite {:partner_user_id nil, :id_space "d"}}]

Oh, right, missed those. Thanks

so I think doing (apply str (map-matches match)) instead of just (map-matches match) solves it

so that str is operating on 4 strings instead of two lists of strings and two strings

Nice, glad to hear it

ty for the help

ah, if you are doing any sort of side-effecty thing, put it inside a doseq

so instead of (doall (map println (map my-fn my-coll)))

do (doseq [coll (map my-fn my-coll)] (priintln coll))

it is not recommended to do a println inside a map

or any type of IO.

Hmm, @roberto If true, someone should update the docs

https://clojuredocs.org/clojure.core/doall

yeah, but he had (doall (map println (map my-fn my-coll)))

if he wanted to print the entire coll: (doall (println (map my-fn my-coll)))

instead of that extra map

Ah, got it

the side effect fn is println

map shouldn’t have any side effects

Oh, nevermind, I don't get it

If you look at the documentation, it suggests that println is the most common use of doall

yes

ah, I jus saw the example, that has never worked for me

All of the examples are (doall (map println col))

ran into bugs with that

Does anyone know more about OAuth in Clojure? I am generally an oauth failure as I still can't handle it. Even Clojure doesn't make it better. After trying around with clj-oauth and oauth-clj I am feeling even more stupid... How do I get this http://apidev.bricklink.com/redmine/projects/bricklink-api/wiki/Authorization to work with Clojure? I probably need the explanation in a format fitting for a ten-year-old 😥

Oh. It's OAuth v1.0 and I don't have any signing URIs ...

what are you using as your provider?

I’ve been able to use oauth with both Heroku and Google as my providers.

if you are using Google, this is a very convenient library https://github.com/Mayvenn/friend-google-openid

I'll look into it, thanks

I’d like to use immuconf which defines some reader tags here

https://github.com/levand/immuconf/blob/master/src/data_readers.clj

when I experiment from the repl, I’m getting a java.lang.RuntimeException: No reader function for tag immuconf/override

Hm.. It seems that doesn't solve my problem. It's 'just' about the Auth header. What I am doing is programming against bricklink's API. I don't think I have a provider there

do I have to move that data_readers.clj file out of immuconf and put it inside my project’s src dir?

figured out I can do this so that it works in the repl

I wonder why the repl doesn’t seem to recognize the data-readers.clj that’s inside the immuconf jar? Oh well, moving on!
