Hello folks, is anybody using with-cp? Can you confirm it does not include :source-paths?

summoning @micha ^ 😄

hmm one sec i will verify

yeah it seems like it does not

https://github.com/boot-clj/boot/blob/master/boot/core/src/boot/task/built_in.clj#L350

@micha do you think an option is preferrable so that we don't break the current "jars-in-jars-out" behavior?

hm

what is the use case?

I create cp for working at the repl

and without src is a bit tough 😉

has anyone used mount with boot-reload in cljs? i'm hitting an issue where on reload, mount throws a very cryptic error: Uncaught could not start [#'myapp.ui.core/ui] due to TypeError: Cannot read property 'cljs$core$IFn$_invoke$arity$1' of null

the stack trace in the dev console only points back to the defstate where that var is defined

I think I'm just gonna ditch mount on the frontend; it's not doing much that a simple start, stop and reload set of functions couldn't do

@pandeiro here is an example of the boot project with mount and (reload): https://github.com/tolitius/hubble the error you posted is most likely not related to mount, and comes from the :start function of #'myapp.ui.core/ui

@tolitius Thanks, you're right. I've tracked it down to how I'm trying to unregister re-frame handlers in my :stop function; something I was doing there prevented the :start function's registering of handlers

Btw @tolitius is mount self-host compatible? (And how much work would it be to make it so?)

Question for you guys: Is there a way to define private tasks like private functions? I have a number of tasks that always rely on calling another task but I can’t figure out how to (comp) that task within the task definition. For example, this is what I’m currently doing:

(boot/deftask PRIVATE-reset-and-seed-database!
  [e environment VAL kw "Environment to use #{dev production}"]
  (fn [next-task]
    (fn [fileset]
      (reset-and-seed-database-fn environment)
      (next-task fileset))))

(boot/deftask reset-and-seed-database!
  [e environment VAL kw "Environment to use #{dev production}"]
  (comp
    (wordroot-util/data-readers)
    (PRIVATE-reset-and-seed-database!
      :environment environment)))

(boot/deftask reset-and-seed-database!
  [e environment VAL kw "Environment to use #{dev production}”]
  (comp
    (wordroot-util/data-readers)
    (fn [next-task]
      (fn [fileset]
        (reset-and-seed-database-fn environment)
      (next-task fileset))))

Actually it looks like that latter case is working...

You can try putting the meta ^:private between deftask and name

If I remember correctly they won't show up in the help @chooie

Perfect - thanks @richiardiandrea!

Hi all, if I start embedded jetty server - watch and sass tasks are not working

(deftask build-dev []
  (comp
   (watch)
   (sass)
   (aot :namespace '#{blog})
   (target)))

(deftask server []
  (build-dev)
  (blog/-main))

(defn -main [& args]
  (component/start (system)))

PLease advice, how can I fix this?

server needs to be wrapped in comp

oh well not exactly

you should have a separate task that starts the server

something like this:

(deftask start-server [] (let [d (delay (blog/-main))] (with-pass-thru [_] @d)))

(deftask server [] (comp (build-dev) (server)))

works!

thanks

the problem is that boot has two stages

Can you please advice where I can more info on with-pass-thru? (shall i just google?)

the pipeline construction phase, and then the execution phase

the task constructor can do some work, like setting up resources

but this is only done once and before the tasks are actually executed

other than setting up resources, the constructor also returns a function, which is the actual workhorse of the task

with-pass-thru is just a thin wrapper around returning a fn (and keeping the fileset as it is)

i see...

thanks a lot

this comes up a lot, I'll add a snippet to the wiki

it would be helpful

@richiardiandrea, you mean whether it is .cljc and works in the same way on jvm and js?

@tolitius no I was wondering whether it would run in JavaScript with no JVM, macros are positioned in a slightly different way for it to work: http://blog.fikesfarm.com/posts/2015-06-19-portable-macro-musing.html

I will have a look as well

@richiardiandrea yes, it does work in JavaScript with no JVM. in cljs case, because :advanced compilation mode renames and shuffles all the nss, it works via a "derefable" state: https://github.com/tolitius/mount/blob/master/doc/clojurescript.md#managing-state-in-clojurescript (i.e. you @ a state when you need to use it)

@tolitius that's great, gotta try with lumo then

@richiardiandrea this is exciting 🙂 let me know how it goes

@tolitius wait until I'll bug you with issues 😁

Is there a way to tell boot/cljs to put the "out" directory somewhere else? (like inside of target) -- it's screwing up helm-projectile-ag (which greps ALL FILES INSIDE PROJECT) ,, and unfortunately, "out" directory is inside project so it (1) SLOWS DOWN search and (2) returns USELESS JS

@qqq add it to .gitignore

helm-projectile-ag still hits it

Add it to.agignore

interesting; thanks!
