17:08 tbaldrid_: these are reader issues, legal symbols can be anything.
20:10 neilmarcus: hello?
20:10 clojurebot: BUENOS DING DONG DIDDLY DIOS, fRaUline neilmarcus
20:25 ravster: whats the max that java.lang.Integer can go to? I'm trying to use the java.awt.Polygon class to find if a given latitude and longitude is part of a polygon, and I'm not sure by how many decimal places I can move a value (Egs: latitude 44.35745968346 -> 4435745968346 )
20:26 hiredman: ,Interger/MAX_VALUE
20:26 clojurebot: #<CompilerException java.lang.RuntimeException: No such namespace: Interger, compiling:(NO_SOURCE_PATH:0:0)>
20:26 hiredman: ,Integer/MAX_VALUE
20:26 clojurebot: 2147483647
20:26 hiredman: ,Integer/MIN_VALUE
20:26 clojurebot: -2147483648
20:26 hiredman: ,Long/MAX_VALUE
20:26 clojurebot: 9223372036854775807
20:26 hiredman: ,Long/MIN_VALUE
20:26 clojurebot: -9223372036854775808
20:27 ravster: hiredman: oh, I wish I could use longs. But the Polygon class doesn't seem able to consume them.
20:27 hiredman: and thanks for the answer. :)
20:29 * ravster doesn't like arbitrary limits to argument values.
20:29 * ravster *grumble* *grumble*
20:38 noprompt: when using require is it possible to both refer and rename?
20:40 or is it ok to use use in that case?
20:42 oh, there it is.
20:46 bttf: brand new to clj ... just wrote some code in my core.clj, trying to run it in my 'lein repl' ... i do (in-ns 'testing-clj.core) to get into the namespace but it seems not able to see my symbols
20:51 it seems that i'm entering that namespace but completely separate from what i have defined in src/testing_clj/core.clj
20:53 ivan: does it work without (:gen-class)? are you sure you're doing (in-ns 'testing-clj.core) and not (in-ns 'testing_clj.core)?
20:54 `hello` shouldn't even compile because `hi` is defined after it, though I don't know how AOT works with that
20:54 bttf: ivan: thanks for replying, i have since removed (:gen-class) since i am not using it ... when I do lein compile i get no output whatsoever .. i don't even know if lein see's the file
20:55 i mean, i just generated a new project ,wrote the code and did a 'lein compile'
20:55 ivan: you don't need to lein compile before lein repl
20:56 bttf: ok
20:57 and yes i'm sure i am doing (in-ns 'testing-clj.core)
20:58 i've rearranged the functions, same issue
20:58 * ivan tries
21:00 ivan: bttf: I'm probably missing something obvious, it's not working here either
21:01 bttf: ok ... does somehing need to be specified in the project.clj ? id assume that it should be set to go
21:03 ivan: bttf: maybe it's because your directory starts with "test"
21:04 lein might be ignoring those by default
21:04 bttf: weird, let me try
21:04 ivan: make sure you change the (ns too
21:06 bttf: heh, actually you need to (require 'testing-clj.core) first
21:06 (in-ns) does not seem to load things
21:06 dakrone: amalloy_: cool, will look when I can
21:07 bttf: ivan: ahh that works, thank you
21:10 I find it hard to believe this doesn't exist already
21:11 ivan: bttf: you can put :main testing-clj.core in project.clj to load and enter that namespace
21:13 bttf: ah cool thanks
21:14 jhawk28: can anyone give be some suggestions on creating a DSL?
21:14 I want to create a subset of the language that is mainly arithmetic/boolean with some specific functions
21:15 but I need to to be limited since the code is "dynamic" and can potentially be unsafe
21:16 is there a way to remove all functions from the dsl's namespace and only add in the specific ones I want?
21:16 or do I need to just read in the data as ebn and then execute it myself
21:17 ivan: I think I would use edn and a whitelist
21:17 mthvedt: jhawk28: you want to read in untrusted data that's a subset of clojure?
21:17 nightfly: clojail might be useful
21:17 jhawk28: yes, a subset
21:18 bttf: ivan: what about reloading a file in the repl? i'm trying (load-file) but its not cooperatng
21:19 mthvedt: you could walk the tree and throw out anything not on the whitelist
21:19 ivan: bttf: probably (require 'testing-clj.core :reload)
21:19 mthvedt: after reading it in as edn
21:19 ivan: there's also a :reload-all
21:20 also nrepl.el has many conveniences for sending new forms to the repl
21:20 bttf: nice, it works
21:21 ill check out nrepl.el
21:22 there isn't a vim equivalent is there? ;)
21:22 brehaut: mdeboard: cool; pity you have to double handle the group names :/
21:22 mdeboard: Yeah. Either that or uh
21:22 parse the patterns :P
21:22 jhawk28: thanks, I think the edn or the clojail may work
21:22 brehaut: （╯°□°）╯︵ ┻━┻
21:22 mdeboard: brehaut: I'm sure there's a much better way of handling that
21:22 ┬──┬◡ﾉ(° -°ﾉ) chill out bro
21:22 dat emacs macro
21:23 mdeboard: never got to use it in the wild before
21:23 brehaut: ha
21:23 bttf: brehaut: are you flipping tables
21:23 brehaut: yes
21:23 bttf: awesome
21:23 brehaut: regexps bring out the worst in me
21:29 ,(re-pattern (str #"\w" #"\d")) ; mdeboard
21:29 clojurebot: #"\w\d"
21:29 brehaut: mdeboard: that'll save you having to escape all your slashes in your regexps
21:36 mdeboard: brehaut: Oh, didn't think that works, using the regex reader
21:37 as args to str
21:37 brehaut: mdeboard: str takes anything that has a toString method (ie, everything)
21:38 regex patterns happen to have a very useful toString
21:38 its perhaps not immediately obvious though; i learnt the trick from weavejester
21:42 mdeboard: brehaut: Cool, thanks for the pointer
21:56 mikepence: reading the joy of closure
21:56 <3 new stuff
22:05 bttf: anyone good with vim-fireplace in here ?
22:07 TimMc: Almost certainly. If you have a question, ask and find out!
22:10 joegallo: that was the question, he was just checkin' ;)
22:11 bttf: well, i'm moving my cursor to a namespace and trying 'gf' .. it's complaining about several things, the first one is that its unable to resolve a symbol that i've not implemented yet (this is the test)
22:11 and when i try :Eval ( ... ), whatever i try it gives me the same complaint of unable to resolve symbol
22:12 tpope: is your file requirable?
22:15 bttf: tpope: my apologies, the hopping stops here
22:16 in the repl i can require the file no problem
22:16 is there a fireplace command for require
22:17 tpope: there is, :Require
22:17 it also implicitly requires the current namespace if it's your first time evaluating code in it
22:18 which I assumed was what was failing, albeit with a pecular sounding error
22:18 can you refheap the error?
22:18 use :messages to see it again
22:19 bttf: i don't see the 'unable to resolve symbol' errors in messages
22:19 but i do see the others, dealing with 'Error detected while processing function <SNR>36_GF..fireplace#findfile..<SNR>36_eval'
22:20 tpope: what are you pressing gf on?
22:23 is that your alterego? same error right down to the example
22:24 oh, because it's from the tutorial, herp derp
22:24 bttf: nope and yes, the tut
22:25 tpope: bttf: to be clear, you can require the *test* file, correct?
22:26 bttf: (clojure.core/require 'command-line-args.core-test :reload)
22:26 CompilerException java.lang.RuntimeException: Unable to resolve symbol: parse-args in this context, compiling:(command_line_args/c
22:26 tpope: well, that's the root of the problem
22:26 the error is messier than it should be
22:27 bttf: messier or misleading?
22:27 tpope: it says couldn't require command-line-args.core-test plain is day
22:28 it's just surrounded by 5 lines of vim garbage
22:28 bttf: oh i see
22:29 but when I require the test, i only get the error i pasted just above
22:29 unless the other erros are hidden away somewhere
22:29 tpope: well it's one level of abstraction up. requiring the file tells you what went wrong. doing something that implicitly requires the file tells you the file couldn't be required
22:30 I just reproduced it. there's another error that happens at the top that tells you exactly what you're looking for
22:30 mthvedt: is there a macro that's like memoize, but for an inline chunk of code
22:31 to execute it exactly once
22:34 amalloy: mthvedt: delay
22:35 tpope: bttf: I just cleaned up the error on gf and ]d. let me know if you find others
22:35 bttf: alright, ill give it a try
22:36 mthvedt: amalloy: delay returns an object that can be derefed, i want to skip that intermediate step
22:36 amalloy: mthvedt: in that case, all code always, is executed exactly once :P
22:37 mthvedt: it would have made this one thing i'm writing more readable… but never mind
22:41 bttf: tpope: looks good so far
22:42 but cpR isn't doing anything for me.
22:42 and i've deleted my function definition from the code and the test isn't giving me the unresolved symbol error that it should, i believe
22:43 tpope: well it only requires once
22:43 after that it's up to you to reload
22:44 bttf: and cpr reloads, no ?
22:46 cpR should reload-all, but i don't see it happening. if i do cpr on each file, i dont see any errors
22:46 tpope: cemerick made me take away cpR :(
22:47 bttf: ooh
22:47 tpope: you can :Require! to reload-all
22:47 * bttf throws shoe at cemerick
22:47 bttf: ok
22:47 still no dice
22:49 tpope: well try :Eval (require ... :reload-all)
22:49 that's all :Require! is doing
22:50 bttf: i did :Eval (require 'command-line-args.core) :reload-all
22:50 then I did, :Eval (clojure.test/run-tests)
22:51 and im seeing errors from when my function existed
22:51 tpope: re-requiring a file doesn't delete the old namespace first
22:52 you can ns-unmap, or just restart your repl
22:52 bttf: interesting
22:52 but if i make changes to my source, shouldnt it automatically update namespace?
22:53 maybe im missing something here
22:53 tpope: ignoring your use of "automatically", it doesn't remove anything
22:54 if you defined a function, it's not automagically undefined just because you deleted it from the file
22:56 bttf: heh
22:56 i guess if the behavior of the function is changed that will be reflected when reloaded
22:57 but if its flat-out deleted? shouldn't that somehow be reflected the same way?
22:57 i guess the repl isn't made to work like that
23:08 thx for the help tpope
23:09 tpope: ta
23:44 dr_choc: Anyone here mess around with clojurescript? Specifically the browser repl?
23:46 brehaut: ~anyone
23:46 clojurebot: Just a heads up, you're more likely to get some help if you ask the question you really want the answer to, instead of "does anyone ..."
23:46 brehaut: (inc amalloy)
23:46 lazybot: ⇒ 49
23:52 dr_choc: Has anyone found the cljs browser repl to be finicky? I'm using the lein-cljsbuild plugin and running lein trampoline cljsbuild repl-listen to get a repl, but sometimes it works and sometimes it just hangs as if the browser never connected, but I can see in the network tab (chrome) that it does connect. Any ideas?
