So what you wrote above is probably working but the new new cider does it differently

And uses the cljs-repl task

interesting, sounds like I should just try stuff and report errors I get into

https://github.com/clojure-emacs/cider/blob/master/doc/up_and_running.md#browser-connected-clojurescript-repl-in-boot-project @qqq

If you find problems yes, report it on cider and I will have a look OK?

@richiardiandrea : will do, thanks!

hello I think I have an error to report in boot-system with the aleph component. it sometimes give an error when it tries to stop

java.util.concurrent.RejectedExecutionException: event executor terminated
                     clojure.lang.ExceptionInfo: Error in component :web in system com.stuartsierra.component.SystemMap calling #'com.stuartsierra.component/stop

everytime I have to kill the jvm 😭

can I add a JAR that’s in my filesystem to the classpath?

@anmonteiro you can use this:

boot.user=> (doc boot.pod/add-classpath)
-------------------------
boot.pod/add-classpath
([jar-or-dir classloader] [jar-or-dir])
  A corollary to the (deprecated) `add-classpath` in clojure.core. This implementation
   requires a java.io.File or String path to a jar file or directory, and will attempt
   to add that path to the right classloader (with the search rooted at the current
   thread's context classloader).

@micha 👌 thanks so much

👍 any time 🙂

when using eamcs+boot, do I want to use cider + cider-nrepl 0.15.0-snapshot or 0.14.0 ?

You shouldn’t need to set it yourself

IIRC cider now injects the right dependencies for you automatically

I know it works for my boot projects

I'm launching boot separately, not via jack-in

but it works now with 0.15.0-SNAPSHOT, so it's all good

ah got it

let's move back to emacs and resolve the orgmode / clj file issue 🙂

I’ve got an substantial annoyance in my cider/boot workflow (boot 2.6.0, [samestep/boot-refresh "0.1.0" :scope “test”]) 1. start boot repl in terminal via boot repl 2. launch a refresh task there (boot-refresh) via (boot (watch) (refresh)) 3. connect to repl from cider so far so good, everything works as expected until I save a file which produces a compile time error: 4. make a change that breaks compilation, save 5. observe irrelevant stack trace in terminal where boot is running

It is possible to get a relevant exception with cider (by evaling the last saved buffer), but it’s a pain

I'm using boot/cljs . I don't want the js files ot get sent ot "./out" -- I want them sent to "../build/out" (where "." = dir where build.boot resides) I'm looking at (doc cljs) but don't see the option. How do I tell the compiler to put the output at "../build/out" instead ?

@qqq have you tried passing it to :compiler-options {:output-dir ...} ?

how do I lookup the documentation for :compiler-options ?

I was unaware of the :output-dir option

boot-cljs probably only exposes the more common compiler options

https://github.com/clojure/clojurescript/wiki/Compiler-Options#output-dir

with boot-cljs you can not set output-dir

> NOTE that the CLJS compiler's :output-to and :output-dir options will be overridden by the cljs task. These options are determined by the name and location of a .cljs.edn. By default the cljs task will automatically create a main.cljs.edn file in the root of the fileset, which will result in a main.js in the root of the output directory.

https://github.com/boot-clj/boot-cljs/wiki/Usage

In our dev task when I change a server side .clj file, our ClojureScript gets reloaded which triggers an http request and this evaluates the touched .clj file. How do I get cljs to reload only when a client side file has been touched?

I think the reload task is what this triggers

Probably I should use: only-by-re

Hmm, that conjes vector of path regexes

I think you're on the right track. Worst case, you could make your own watch task and use fileset diff stuff directly

I want to make this for out big cljs app too. The clj doesn't need refresh because we're using wrap-reload ring middleware

Yes, we do it like that as well.

But I don’t want it to be evaluated on save by this loop 🙂

Yeah. I think only-by-re is handy when there is some cljs you don't want to recompile

I used it recently to not reload web workers

I suspect it would be more of a watch task thing

When I run boot I get an error. It says it's downloading boot.jar and then it fails with unknownhostexception: http://github.com. I configured our corporate proxy with BOOT_JVM_OPTIONS, but it seems to be ignoring it.

Any ideas?

is the proxy used for DNS queries?

@pupeno can you paste your options please?

I made some progress. Boot on Windows ignores environment variables and boot.properties, but boot.l4j.ini works.

Now, apparently, my proxy has an invalid SSL cert :(

ah yeah, that might be a setting you need to do with the jvm configuration?

on linux there is a way to add CAs to the JVM's key store thinger

@qqq what I do is to append a sift task at the end of the pipeline

Filtering away .out or renaming it

Where does boot store libraries that it downloads for your project?

Is it just in ~/.boot/cache

that would be in your local maven repo

it's at ~/.m2/ by default

ah awesome

@richiardiandrea : sift definitely would work; however, I already have a (target) so I just hijacked that to put it elsewhere

any suggestion what to debug when I see an exception for Multiple jar entries match: .*/pom.xml after trying to boot push an uberjar?

nvm. figured it out!

should I not be boot pushing an uberjar? pipe breaks during transfer

@uwo had the same problem and I solved by specifying :project. It maybe happens because of the many pom.xml in the uberjarring, but @micha might know more
