is organizing closurescript namescapes like this idiomatic? https://github.com/madvas/fractalify/blob/081fcc12081e978a3b183f5f5d9ea2d71204225f/src/cljs/fractalify/main/view.cljs#L4-L8

I find [fractalify.components.dialog :as dialog] verbose.

the function we want to use here is fractalify.components.dialog/dialog the naming is too long.

is there a way to reduce it to fractalify.components/dialog but keep the dialog function in its own file?

I cannot reproduce https://github.com/clojure/clojurescript/wiki/Dependencies#bundling-foreign-javascript-code with Clojurescript version 1.7.170. Is it still valid?

@mike: You can use :refer to require specific vars: [fractalify.components.dialog :refer [dialog]]

@mike: well, I'm not sure how idiomatic it is, but I do name things like that - I want to have things in separate namespaces, but don't want to refer to long names, so I use :as to alias the namespace.

It might be slightly verbose, but it's just an import you do once (and your editor/IDE might also be able to do them for you)

so, it's not the same as goog closure namespacing.

@mike: No, see http://clojurescriptmadeeasy.com/blog/when-do-i-use-require-vs-import.html.

thanks.

@jindrichm: yes it works

this is how CLJSJS works which many people depend on

@dnolen: I followed the Quick start and the mentioned documentation of 'Bundling "Foreign" JavaScript Code', but when I launch browser REPL and run (require '[yq]), then it cannot be found: clojure.lang.ExceptionInfo: No such namespace: yq, could not locate yq.cljs, yq.cljc, or Closure namespace "yq" {:tag :cljs/analysis-error}

@jindrichm: I cannot help you with your specific problem

but the wiki is up-to-date and correct on dependencies

nothing has changed in almost a year

@dnolen: Is it correct to provide :foreign-libs to cljs.build.api/build?

@jindrichm: compiler options are always provided in the same way

draw your conclusion from this more general statement

@jindrichm: the exception is trying to give you more information

which is that the dependency could not be found

so my guess is that you do not have the file on the JVM classpath

@jindrichm: also you said “browser REPL"

which doesn’t know anything about cljs.build.api/build

so you will need to duplicate whatever compiler options you are using when constructing the REPL

@dnolen: Do I need to provide the :foreign-libs option to cljs.repl/repl too? (Ah, you just answered that...)

yep

@dnolen: How do I pass compiler options to cljs.repl/repl? (doc cljs.repl/repl) is empty.

@jindrichm: this is implied in the Quick Start

you just pass compiler options as keyword arguments

or use cljs.repl/repl* which takes a compiler options map

Finally, I made it work. Thanks, @dnolen for the help!

np

Do you have to place externs file on the class path (or :source-paths if using cljsbuild)?

If I want to throw a js Error from a macro that needs to be in a .cljc file correct?

I can't seem to evaluate let bindings inside of a #js {} expression... is this expected behaviour?

I get a compiler warning

WARNING: Use of undeclared Var sme.handlers/message at line 16 src/sme/handlers.cljs

(go
  (let [status (<! ch)
        message (case status
                  :up-to-date "Up to date."
                  :updated "Updated.")
        response #js {"message" message}] ;; line 16
    (js/console.log message) ;; line 17
    (.json res response)))

note that I don't get a warning for line 17

and the console.log works just fine there

it would be simpler to alts! on status

@pat: how would you use it here? I'm not quite sure what it does, after reading the docs

My brain is mushy so may be wrong, but i think core async has idioma for doing case like stuff

Dirac is shaping up nicely, see the “Scope” panel: https://dl.dropboxusercontent.com/u/559047/dirac-source-panel-enhancements.png https://github.com/binaryage/dirac#features

un-mangled variable names? Neat ❤️

right now, it is just extracting a nice prefix and adding an index number, but for eval’ing cljs in the context of debugger I want to have some nice solution, so that you can mention variable names you see in the scope panel and they would reference real generated names

I think there will be clash with active repl namespace anyways, while in debugger, local names have to be referenced as js/name from cljs

@darwin: dirac looks great 👍
