1:33 tolstoy: Why would that reloaded.repl thing, when you call "reset-all", when not changing any code, cause a "namespace not found" issue?

1:36 Hm. lein clean fixes it? Weird.

2:00 ilevd: How can I transform enlive node back to html?

2:07 om: ilevd: if memory serves, enlive-html/html

2:12 ilevd: memory doesn't serve well: it's emit*

2:21 ilevd: om: thanks, with (apply str .. ) it seems work

2:21 om: ilevd: I forgot to say it returns a seq

2:22 ilevd: I had to take a look at the a mailbox processor I wrote some time ago

2:29 ilevd: I think it must be a public lib api method

2:56 ashnur: so, I am working with mori data structures which is close enough to what you have to ask here, how would you accomplish this? https://gist.github.com/ashnur/34e241049825d1e66ce5519c20c52689

3:01 TEttinger: hi ashnur

3:02 ashnur: hi :)

3:03 TEttinger: this is uh confusing. I'm not sure why the keys are 1 and 5, and the values "c" and "j"

3:04 maps in clojure and maybe mori are unsorted when made with the {} literal

3:04 I think for maps of less than 8 keys the sort order is "usually predictable", but that is an implementation detail on clojure and may not be true for cljs/mori

3:08 ashnur: keys and values are such because this is example data, the original data is way more confusing with stupid names

3:09 TEttinger: I just don't see the relationship at all

3:09 ashnur: and i want a vector back, so that's ordered just fine

3:09 [{1:"c"}, {5: "j"}] this is a list of hashMaps

3:09 TEttinger: oh there we go

3:09 I see now

3:10 ashnur: yeah, i wasted a night to figure out the relationships, there is actually way more data, it's coming from a Java backend

3:11 TEttinger: it looks up key x in the rec map to get the end result key of 1. in the second half of the data, it looks up key z in rec to get "c"

3:12 in mori, are rec and order equivalent to "rec" and "order", that is, they're strings but you can omit the quotes?

3:13 ashnur: this is javascript and the object (hashMap) keys are always strings everywhere

3:13 so I think yes?

3:14 rec has the data from which the keys and values have to be chosen by the value of they key attribute and the put into objects using the order attribute

3:14 so easy to write down in english :))

3:16 and what's even worse, i simplified this because even the value of the key is actually coming from a list so i have a lookupf function for that

3:16 i love good backend APIs.

3:17 TEttinger: ,(def data [{ "key" "x", "values" [ {"order" 1, "rec" {"x" 1, "y" 2, "z" 3}}, {"order" 2, "rec" {"x" 5, "y" 7, "z" 9}}]},{ "key" "z", "values" [ {"order" 1, "rec" {"x" "a", "y" "b", "z" "c"}}, {"order" 2, "rec" {"x" "h", "y" "i", "z" "j"}}] )

3:17 clojurebot: #<RuntimeException java.lang.RuntimeException: Unmatched delimiter: )>

3:17 TEttinger: gah

3:18 ,(def data [{ "key" "x", "values" [ {"order" 1, "rec" {"x" 1, "y" 2, "z" 3}}, {"order" 2, "rec" {"x" 5, "y" 7, "z" 9}}]},{ "key" "z", "values" [ {"order" 1, "rec" {"x" "a", "y" "b", "z" "c"}}, {"order" 2, "rec" {"x" "h", "y" "i", "z" "j"}}]}] )

3:18 clojurebot: #'sandbox/data

3:19 TEttinger: so that's one problem, there was a missing square bracket I think

3:20 ashnur: yes, thanks for pointing it out

3:21 fixed the example :)

3:21 i need something like parinfer for javascript :D

3:31 TEttinger: ,(def data (atom [{ "key" "x", "values" [ {"order" 1, "rec" {"x" 1, "y" 2, "z" 3}}, {"order" 2, "rec" {"x" 5, "y" 7, "z" 9}}]},{ "key" "z", "values" [ {"order" 1, "rec" {"x" "a", "y" "b", "z" "c"}}, {"order" 2, "rec" {"x" "h", "y" "i", "z" "j"}}]}] ))

3:31 clojurebot: #'sandbox/data

3:33 TEttinger: ,(def data [{ "key" "x", "values" [ {"order" 1, "rec" {"x" 1, "y" 2, "z" 3}}, {"order" 2, "rec" {"x" 5, "y" 7, "z" 9}}]},{ "key" "z", "values" [ {"order" 1, "rec" {"x" "a", "y" "b", "z" "c"}}, {"order" 2, "rec" {"x" "h", "y" "i", "z" "j"}}]}] )

3:33 clojurebot: #'sandbox/data

3:35 ashnur: i have no idea what's happening

3:35 TEttinger: I'm workin some magic

3:46 hooray!

3:46 ,(let [atm (atom {})] (doseq [{:strs [key values]} data] (doseq [{:strs [order rec]} values] (swap! atm assoc-in [order](rec key)))) @atm)

3:46 clojurebot: {1 "c", 2 "j"}

3:46 TEttinger: it doesn't quite work yet

3:46 ashnur: holy shit that's longer than expected

3:47 at least 3-4 things i never used

3:47 from that list

3:58 amalloy: why on earth would you use an atom for that

3:58 it's just a reduce over the thing you're currently holding in the atom

3:59 TEttinger: ,(let [atm (atom [])] (doseq [{:strs [key values]} data] (doseq [{:strs [order rec]} values] (swap! atm update-in [(dec order)] #(vec (concat % [(rec key)]))))) (mapv #(apply hash-map %) @atm))

3:59 clojurebot: [{1 "c"} {5 "j"}]

3:59 TEttinger: I'm kinda brain-blocked right now

3:59 I'm currently helping 3 different people, two of them in a java channel

4:02 amalloy, is it just a reduce though? his data seems to call for updating different parts of the returned value based on the value of the order key

4:02 I guess anything CAN be a reduce

4:03 amalloy: you turn the doseq into a nested (for), producing a list of operations to perform

4:03 and then you reduce over those, doing the swaps as pure functions on the accumulator

4:04 or really it looks like it's so simple you don't even need to reduce, you can just (into {} (for ...))

4:04 TEttinger: the underlying algorithm isn't what I'd call simple

4:04 it might work

4:04 try it

4:04 amalloy: you're really talking about this snippet? (let [atm (atom {})] (doseq [{:strs [key values]} data] (doseq [{:strs [order rec]} values] (swap! atm assoc-in [order](rec key)))) @atm)

4:05 TEttinger: the data that it needs to output is weird

4:05 amalloy: (into {} (for [{:strs [key values]} data, {:strs [order rec]} values] [order (rec key)]))

4:05 i don't see how that's weird at all

4:05 TEttinger: nope

4:06 not correct

4:06 ,(into {} (for [{:strs [key values]} data, {:strs [order rec]} values] [order (rec key)]))

4:06 clojurebot: {1 "c", 2 "j"}

4:06 TEttinger: he needs the keys to be 1 and 5, looked up in the "x" key for the first map

4:06 [{1 "c"} {5 "j"}] is the desired output

4:07 amalloy: i took the first version you wrote, which as you say doesn't work yte

4:07 TEttinger: yeah, I posted a working one

4:07 ,(let [atm (atom [])] (doseq [{:strs [key values]} data] (doseq [{:strs [order rec]} values] (swap! atm update-in [(dec order)] #(vec (concat % [(rec key)]))))) (mapv #(apply hash-map %) @atm))

4:07 clojurebot: [{1 "c"} {5 "j"}]

4:07 amalloy: and wrote something equivalent without a doseq or an atom

4:09 it would probably be a good exercise for you to perform the same transformation i did on your unfinished solution

4:09 there's nothing weird or special about the requirements, and it transforms into a reduce/for perfectly well

4:10 TEttinger: it just seems kinda... imperious to not even address ashnur who asked the question and only critique the solution. I mean it could be better, and I'll do the improvement when I have time

4:13 amalloy: it was unnecessarily rude of me to lead with "why on earth would you do that"

4:15 but i'm not especially interested in the 0th-order thing of answering every specific question in #clojure myself. i actually answered a *very* similar question earlier tonight, which you can see if you look through the logs for bmuk's question

4:15 rather, i want to improve the answers given by the channel whether i'm here or not, which means code reviews of answers that could be better

4:16 in particular from regulars who i would expect to be recommending functional solutions

4:16 TEttinger: I was kinda thrown off by the initial figuring out the data

4:16 this is what I started with: https://gist.github.com/ashnur/34e241049825d1e66ce5519c20c52689

4:17 amalloy: yeah, figuring out someone's crazy input format and how they intend it to be related ot their output is not easy

4:18 TEttinger: and that's the cleaned up version too... apparently the server-side code outputs even nastier results

4:24 ashnur: yeah, the Java backend guy just dumps json on me from Hibernate

4:24 and this is some virtual tables stored in pgsql. tables stored in tables :D

4:25 and thanks for the help TEttinger

4:26 TEttinger: I'd take a look at what amalloy had for an improvement that should both perform better and scale more cleanly to more complex data

4:26 ashnur: i will do that too, i am asking these questions because the way clojure handles data seems really down to earth and want to practice it

4:27 need to leanr it eventually :)

4:31 alexelcu: @tobyirc @dysfun @jjmalina Hello, I'm a Scala developer and I like Clojure as well and trying to learn more. There's lots to learn from Scala though, things that you won't learn from Clojure and the reverse is also true and neither of them is a dead-end. Scala follows idioms and design patterns that are more common in the very static languages from the ML family / Haskell / Idris, etc. For example Scala developers are very much into modeling of types and

4:36 TEttinger: ah!

4:36 ashnur:

4:36 ,(mapv #(apply hash-map (reverse %)) (reduce (fn [coll [k v]] (update-in coll [k] conj v)) [] (for [{:strs [key values]} data, {:strs [order rec]} values] [(dec order) (rec key)])))

4:36 clojurebot: [{1 "c"} {5 "j"}]

4:37 TEttinger: thanks amalloy, for a firm slap back to functional programming :)

4:37 amalloy: haha, you're welcome. sorry for not doing it as politely as i could

4:38 TEttinger: nah I should be used to your superior technical skills seeming like superiority sometimes

4:39 I'm trying to remember if you work at a place I know of

4:40 facebook, groupon, what is now IBM as clients, nice

4:41 heh, and gfredericks works at or with Groupon, I wonder if there's a connection there

5:24 sobel: amalloy: i'm so with you on trying to be able to answer every question. i was a regular helper on #postgresql for years and it did more for rounding out my knowledge than pretty much anything else i did

7:16 gizmo385: So in the application that I'm working with, I'm trying to update a global state value. I've tried both atoms and dynamic variables, but no matter what I do, I can't seem to get the value to update until after the entire execution thread terminates?

7:16 For example, if I run my functions in the REPL and check the values of the atom/global AFTER the function finishes in the REPL, then the value is what I expect

7:16 But If I try to check the value mid-execution, it never changes. What gives?

7:17 gxx3: is clojure as interactive as CL with slime?

7:17 gizmo385: Any ideas on how to properly structure this so that it updates the variables immediately after calling set!, swap!, or whatever function I need to call to update the var

7:22 I've also tried it with refs and that isn't working either?

7:27 Kneiva: gizmo385: can you show some code?

7:28 kwladyka: gizmo385 i wrote article in that topic a few days ago clojure.wladyka.eu - maybe it will help you.

7:30 gizmo385: Yeah, let me put it in in a pastebin

7:34 ridcully: gizmo385: i ask, because we had this yesterday and misery loves company: are you actually realizing the result when you modify your atom? if your manipulation happens in something lazy it might not happen until you print it in the repl e.g.

7:35 gizmo385: @Kneiva @kwladyka @ridcully Here is the code that describes the state with a use example on the bottom: http://pastebin.com/96HmXui1

7:36 If I actually call the function I have at the bottom of the paste in the REPL, the value on :failure comes out to false even if raise-error! gets called

7:36 But, if I check the value of the error (by calling error?) in the REPL after the described function /finishes/ then the value is true

7:36 So I would think that something is happening lazily, but I can't figure out what? And I can't find any documentation on how to force the state change

7:37 @Kneiva @kwladyka @ridcully Here is the paste again incase all the disconnections threw it out of the screen: http://pastebin.com/96HmXui1

7:44 kwladyka: gizmo385 i don't have too much time now but try :failure @error-occured?

7:46 eventually you don't call raise-error! before that

7:46 gizmo385: @kwladyka Just retried it, no dice

7:46 kwladyka: just use println in this function to see when it is run

7:46 gizmo385: But in a let, the forms bind in order. Could it not be evaluating the call to (parse ...) until I at it in the map?

7:47 Because I know that raise-error! is getting called at some point since the print statement in raise-error! runs

7:47 I tried the @error-occured to no avail :/

7:50 Got it. The function call isn't getting run. If I print the parse-result and then check the value, it runs

7:50 err it gets the right value

7:52 I feel like there should be a macro or function that I can use that forces non-laziness?

7:53 MJB47: (doc doall)

7:53 clojurebot: "([coll] [n coll]); When lazy sequences are produced via functions that have side effects, any effects other than those needed to produce the first element in the seq do not occur until the seq is consumed. doall can be used to force any effects. Walks through the successive nexts of the seq, retains the head and returns it, thus causing the entire seq to reside in memory at one time."

7:58 gizmo385: @MJB47 That certainly help :)

7:58 Thanks a bunch everyone :D

8:44 mpenet: gxx3: yes, cider is an equivalent of slime for clojure

8:46 gxx3: clojure-mode actually used slime internally in the past, until it was replaced by something more customizable/upgradable for clojure. So you'll find a ton of keybinding/features inherited from slime for instance

9:45 asdf12z_: do a lot of people use speclj ? bdd test framework or the built in for clojure ?

9:45 can't seem to mark a test pending in clojure.test

10:28 Guest35203: Anyone have any recommendations on schedulers? I'm looking at using Chime or Quartzite

10:54 seangrove: Hey all, struggling with an error, "java.lang.IllegalArgumentException: Cannot open <nil> as a Reader., compiling"

11:38 justin_smith: Guest32455: I've had good luck with just using the ScheduledThreadPoolExecutor which comes with the jvm https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ScheduledThreadPoolExecutor.html

11:39 Russell-: Oh yes, there is. http://stackoverflow.com/questions/10957257/clojure-debugging-println-line-number-and-file-name

11:41 justin_smith: asdf12z_: I am pretty sure clojure.test has no concept of "pending", in fact I have no idea what a "pending test" would be

11:42 Glenjamin: a test title with either no implementation, or one that's known to not be working

11:43 often a TODO as a testcase, that doesn't fail the build

11:54 gigasquid: https://gist.github.com/Medeah/2bc6e92b86ae7e8abc14

11:55 justin_smith: (inc gigasquid)

11:55 nice

12:12 russellw: I'm confused about the macro in the accepted answer in http://stackoverflow.com/questions/10957257/clojure-debugging-println-line-number-and-file-name - in particular about printing the name versus value of the argument

12:12 ~(pr-str x) prints the name of the argument but ~x prints the value. How can that be?

12:12 clojurebot: Excuse me?

12:12 russellw: I would have expected either both to print the name or both to print the value

12:16 justin_smith: russellw: I bet macroexpand would help

12:18 ,(defmacro thing-and-string [x] `(list ~(pr-str x) ~x))

12:18 clojurebot: #'sandbox/thing-and-string

12:19 justin_smith: ,(macroexpand-1 '(thing-and-string +))

12:19 clojurebot: (clojure.core/list "+" +)

12:19 justin_smith: russellw: at the time of expansion, + is just a symbol, so emitting the string emits the string of that symbol. The value emitted by the macro is then evaluated when it is run.

12:21 russellw: justin_smith, oh! That makes sense, thanks

12:22 justin_smith: russellw: a big a-ha moment for me about macros is that you could just return a list of symbols, and that would be the code that gets compiled

12:22 ,(defmacro demo [] (list 'println "hello" "world"))

12:22 clojurebot: #'sandbox/demo

12:22 justin_smith: ,(demo)

12:22 clojurebot: hello world\n

12:23 justin_smith: when we use helpful things like ` we can forget that is all they are doing sometimes

12:23 russellw: Yeah, I guess with practice you get used to keeping the two levels of indirection straight

12:26 Glenjamin: ,(defmacro lemme-see [x] (list 'list (name x) x))) ; attempt to get the same effect without `

12:26 clojurebot: #'sandbox/lemme-see

12:26 Glenjamin: ,(macroexpand '(lemme-see +))

12:26 clojurebot: (list "+" +)

12:27 justin_smith: Glenjamin: nice

12:28 ,(defmacro another-thing [x] (list 'list (name x) (type x) x)))

12:28 clojurebot: #'sandbox/another-thing

12:28 justin_smith: ,(another-thing +)

12:28 clojurebot: ("+" clojure.lang.Symbol #object[clojure.core$_PLUS_ 0x2ae38b7a "clojure.core$_PLUS_@2ae38b7a"])

12:30 Glenjamin: ,(lemme-see +)

12:30 clojurebot: #error {\n :cause "Unable to resolve symbol: lemme-see in this context"\n :via\n [{:type clojure.lang.Compiler$CompilerException\n :message "java.lang.RuntimeException: Unable to resolve symbol: lemme-see in this context, compiling:(NO_SOURCE_PATH:0:0)"\n :at [clojure.lang.Compiler analyze "Compiler.java" 6688]}\n {:type java.lang.RuntimeException\n :message "Unable to resolve symbol: lemme...

12:30 clojurebot: ("+" #object[clojure.core$_PLUS_ 0x6295c0bb "clojure.core$_PLUS_@6295c0bb"])

12:31 Glenjamin: ah, earlier i got a read-eval error, but i think that was because of a `~x

12:31 ,`~x

12:31 clojurebot: #error {\n :cause "Unable to resolve symbol: x in this context"\n :via\n [{:type clojure.lang.Compiler$CompilerException\n :message "java.lang.RuntimeException: Unable to resolve symbol: x in this context, compiling:(NO_SOURCE_PATH:0:0)"\n :at [clojure.lang.Compiler analyze "Compiler.java" 6688]}\n {:type java.lang.RuntimeException\n :message "Unable to resolve symbol: x in this context"\n ...

12:54 WorldsEndless: I need to do some XML templating. Anyone done this? Recommendations for libraries or approaches?

12:55 justin_smith: WorldsEndless: hiccup works decently for xml templating (though it doesn't specifically target it, it generates it OK if you use the tags right)

12:55 if you want to programmatically modify the structure clojure.data.xml is nicer though

12:56 WorldsEndless: Okay; clojure.data.xml was what I was looking at

12:56 I don't need to modify the structure but just fill in data values

12:57 justin_smith: yeah, I would use hiccup for that personally

13:01 WorldsEndless: What woudl you read the template with? Hickory?

13:02 justin_smith: WorldsEndless: typically with hiccup the template is inside some templating function, not in a dedicated templating file

13:03 WorldsEndless: I have not tried hickory

13:03 gmcramm: WorldsEndless: Do you already have an xml template that you're trying to modify, or are you creating new ones?

13:03 WorldsEndless: I have an XML template used for Apache FOP

13:03 I need to fill in values

13:04 justin_smith: oh, that's different, I misunderstood

13:04 gmcramm: Ah. IMO hickory might be a better bet then

13:04 You could also look at enlive

13:04 WorldsEndless: I like enlive, but hadn't thought of using it on xml

13:06 gmcramm: It should work just fine with xml. At least, I don't see why it wouldn't.

13:17 WorldsEndless: Oh. Enlive actually has an xml-resource function. Nice!

14:34 sdegutis: Are there any other "escape-html" functions besides in Hiccup?

14:44 Is there a function in clojure.core like this? (fn [f x] (if (f x) x))

14:44 some-> comes to mind but it's not quite right since it returns (f x) if it's non-nil, rather than x itself

14:47 Good afternoon.

14:59 amalloy: sdegutis: incredibly that function exists, not in clojure itself, but rather in every clojure library ever written

15:05 sdegutis: amalloy: yeah that's what I thought

15:05 amalloy: what do you call it?

15:18 tolstoy: When?

15:33 sobel: that's coalesce

15:33 popular sql function

16:46 ben_vulpes: how do i use (.. class method method get-first-thinger) in interopland?

16:47 i want to call .get(0) basically

16:50 Glenjamin: ben_vulpes: most use of .. can be replaced with ->> which imo is a bit clearer (as it's more common)

16:51 amalloy: not ->>, but ->

16:51 and *all* uses

16:51 Glenjamin: ack, yes

16:51 cortexman: tf

16:51 Glenjamin: ,(-> (ArrayList. [(ArrayList. [1])] (.get 0) (.get 0))

16:52 damn, missed a paren

16:52 cortexman: anyone else us a cider clojurescript repl?

16:52 Glenjamin: ,(-> (ArrayList. [(ArrayList. [1])]) (.get 0) (.get 0))

16:52 amalloy: Glenjamin: or just (-> [[1]] (.get 0) (.get 0))

16:52 cortexman: i've noticed that when there are a lot of keyed reagent objects on the page it just times out a lot

16:52 Glenjamin: oh right, i forget vectors have methods

16:53 also, clojurebot appears to be absent :(

16:55 amalloy: Glenjamin: importantly, they implement List

16:55 which is why (ArrayList. [1]) also works

16:55 Glenjamin: yeah, i was thinking in java mode

16:56 presumably (nth (ArrayList. [1]) 0) also works

16:56 amalloy: yes

16:58 Glenjamin: oh, huh - nth also works on regex match objects

16:59 alexei___: For "public BoxUser.Info getInfo(String... fields)" is there anything special about calling this kind of methods? (.getInfo box-user) says "No matching field found"

17:00 ben_vulpes: thanks Glenjamin, amalloy

17:00 ridcully: iirc you need to pass an empty String[]

17:01 it's ok to call getInfo() in java, but not in clojure

17:01 Glenjamin: hrm, i thought it was documented on the java iterop page, but yeah - Type... is actually sugar for an array parameter

17:02 alexei___: Ok, thanks: ^BoxUser$Info user-info (.getInfo (BoxUser/getCurrentUser api) (into-array String []))

17:02 seems to work

17:06 edaq: Hey thought I would mention a new site

17:06 neuro-linguistic-programming.angelfire.com

17:06 it is an interesting topic

17:18 russellw: I noticed that when I run a CPU intensive clojure program, even when I haven't done anything to multithread it, Windows task manager says it's using two, three or even four CPU threads - a pleasant surprise! Is this because the garbage collector is running in separate threads?

17:25 arkh: russellw: depends on your code but garbage collection, future, send and send-off for agents, core async, etc. use their own threads or thread pools

17:25 russellw: Right, I wasn't even using any of the other things, though I was doing a lot of memory allocation

17:26 Glenjamin: when I did something similar, I found that GC was using the other cores

17:26 russellw: This is good, it means you can get at least some benefit from multiple CPU cores without having done any multithreading in your code

17:26 {blake}: OK, given a list where some of the keys are case-insensitive duplicates, provide a consisten way to turn those keys into case-insensitive uniques. Like '(:abra :cadabra :Abra :ABRA) could become '(:abra :cadabra :Abra1 :ABRA4).

17:26 Glenjamin: you might want to look into reducers/fold if you do want to parallelise the computation itself

17:27 {blake}: (I'm counting upper-case letters to give the unique number after the keyword. In case the list isn't always in the same order.)

17:27 russellw: Glenjamin, thanks, I'll keep that in mind

17:27 {blake}: (And the list is created from keys in a map.)

17:28 Glenjamin: {blake}: some sort of loop where you keep a counter and a set of lowercased keys-so-far

17:29 {blake}: Glenjamin: Yeah, that's what I started with. But it's getting uglier than I like. I was thinking of building a map like {:Abra :Abra1, :ABRA :ABRA4...}

17:29 Glenjamin: what is the real goal, this sounds like a bit of a weird thing to want to do

17:30 {blake}: Converting Mongo to SQL. Everything was going so well, until I discovered I had a map with keys like "401k" and "401K". :/

17:30 Glenjamin: and SQL is case sensitive?

17:30 erm, insensitive

17:31 {blake}: Glenjamin: Yes. INsensitive.

17:31 russellw: {blake}, I think the job will become easier if you drop the requirement to preserve case

17:32 {blake}: russellw: There isn't really a requirement to preserve case.

17:32 russellw: {blake}, good, then a map like the one you have in mind, converting the keys to lowercase first, should do the job

17:33 kenrestivo: if i were to while but needed the results of the test, i.e. to log it, what should i use?

17:33 Glenjamin: why does a single entity have keys for 401k and 401K ?

17:34 kenrestivo: i.e. (let-while [foo (some-test)] (log foo))

17:34 russellw: Converting the keys to lowercase after lookup, that is. And I suppose any time a system allows a degree of freedom, bad data will creep in

17:34 Though it might be worth investigating whether those keys should actually be considered distinct

17:34 {blake}: Yeah, this is a...well, this mongo database has been through a lot.

17:34 Some of the results are serialized with nippy. And some are not.

17:35 The date formats change throughout.

17:36 kenrestivo: ah (while (when-let [d (some-test)] (log d) true)) seems to work

17:36 {blake}: By which I mean, sometimes they're dates, sometimes they're strings.

17:37 ridcully: philosophical

17:48 will_sm: Created a webapp using figwheel for some school thing

17:48 My server should be able to handle 200+ people refreshing every 10 seconds right?

17:48 3kb of data each time

17:50 russellw: will_sm, that's not a terribly heavy load so I would think it shouldn't be a problem. (Caveat, I've never heard of figwheel before)

17:50 ridcully: will_sm: you are running figwheel as your primary server? are you asking because you see some problem?

17:51 will_sm: russellw, figwheel is used to get automatic reloading of clojurescript code. The server jetty I think

17:51 russellw: I'm assuming you're asking because it's not actually keeping up with the load

17:51 will_sm: no problem, I have things working on my end, and I've never done anything that is not tiny scale

17:51 russellw: Oh, well that's good then

17:52 will_sm: so clojure is easy to scale in general right?

17:52 russellw: I'm not yet in a position to say for definite, but thus far my impressions of it are good

17:53 The JVM is the world's best heavy duty runtime, and clojure seems to make good use of it

17:53 Just don't use instaparse for non-tiny files :)

17:53 ridcully: figwheel is a productivity drug

17:54 Glenjamin: did you get a parser working russellw ?

17:54 russellw: Glenjamin, the author got back to me, said it was really only intended for files on the tens of kilobytes scale, so I'll probably just write the parsers by hand

17:55 will_sm: figwheel + reagent has been a great experience

17:55 making a ring handler, not so much, but as expected from being an web noob

17:56 Glenjamin: did you look at https://github.com/ericnormand/squarepeg at all?

17:57 russellw: no, trying one parser generator was fun, trying two in succession would be not so much fun to my way of thinking. It's not like writing recursive descent parsers by hand is all that difficult after all :)

17:58 Glenjamin: my favourite approach is to have the state parameter be the function

17:58 russellw: How do you mean?

18:00 Glenjamin: here's a JS example: https://github.com/creationix/mine/blob/master/mine.js#L130

18:01 russellw: ah! That is elegant

18:02 I usually just interface the tokeniser and parser by having a global/module scope variable for the current token. in clojure, that would be done with the tokeniser executing (def tok ...) to set the current token, right?

18:03 Glenjamin: i'd write it as a loop recur I think

18:03 or maybe closure over an atom, wouldn't use a global

18:04 russellw: Also iirc the Java standard library has a line number reader that keeps track of the current line number in the input for you, which I can use

18:04 Not that keeping track of the current line number is difficult, but it's one of those chores that it's all the nicer to have done for you

18:04 {blake}: Got an old clojure web app, which hasn't been deployed in a while. When I try to run it via "java -jar", I get "Could not find or load main class myapp.handler.main." Which, yeah, it's not called "main" so I can see why it wouldn't be found. What I don't know is why it's looking for it "all of a sudden".

18:05 russellw: {blake}, maybe it was previously run with some script or something that pointed it at the right thing?

18:06 {blake}: russellw: So, I could pass it a parameter to point to the right thing, maybe?

18:06 russellw: {blake}, I would think so

18:06 amalloy: ,clojure.lang.LineNumberingPushbackReader

18:07 well, rip clojurebot. that exists, anyway

18:08 russellw: amalloy, ah, sweet, thanks!

18:09 cortexman: can you capture the output of pprint in a variable? it accepts a writer option

18:09 oh, with-out-str looks promising :)

19:02 Kingmob: Anybody have time for a namespace/file/loading question? Does anyone know of a way to force loading of files? I have multimethods whose definitions are in multiple files, but nothing directly "require"s them, so the files aren't being loaded, it seems.

19:04 amalloy: you force files to be loaded by requiring them

19:04 there is no "i need this file to be loaded but i don't want to load it explicitly" mechanism

19:05 Kingmob: I'd originally assumed all files added to a project/jar were loaded, not lazy-loaded.

19:06 ..and was hoping that defining a defmethod in other files would get picked up, since nothing *other* than the defmethod is necessary elsewhere

19:07 Is there a good way to say "require every file in this directory/namepsace"?

19:08 amalloy: no

19:09 {blake}: ,(def r {:abra 1 :cadabra 2 :Abra 3 :ABRA 4})

19:10 Kingmob: ok, thx

20:30 sdegutis: Oh man. Guys.

20:30 justin_smith: ping

21:32 asdf12z_: whenever i write a let binding, often times i want to say... (let [term (if encode (url-encode term) term)] is there an easier way to say that? like update term if x is true only? instead of a if else

21:43 justin_smith: sdegutis keeps logging off, I just got my room at the hotel where clojure/west is happening

21:46 iovechildren: my gf doesnt know but i fuck her 2 autistic 16 year old girls is that bad ?
