is there a way to compile the entire project? I keep having to go to each namespace and compile individually.

no, there’s not

the idea is that people rarely work with all namespaces

and if you compile just the stuff you need

@roberto but there are tools that eagerly load your entire project as a side effect. Clj-refactor is one of them.

there’s also good old lein check

we have an app we make a jar out of and deploy. i’d like to be able to connect to an nrepl service we have in this app and enjoy the full CIDER experience. however, cider is a lein plugin. we don’t use lein to run this app. how would i include the cider nrepl middleware in the jar?

nevermind. rtfm!

Indeed, it's in the manual. 😉

thanks, will look into clj-refactor. So the issue I’m having, is that when I open a project (normally a web app), and want to start it up via the repl, it fails because it says it can’t find various namespaces. I then have to go and compile each namespace individually. But once the server is up and running, I can just compile the stuff I need and it will be hot loaded.

you might want to look into reloaded repl workflow and components. https://github.com/stuartsierra/component

so you would start the repl. run reset which loads all your nses and starts up you webserver (and possible other related compnents of your system)

I am using component

ah do you? sorry

that is exactly what I’m doing

i may be misunderstanding then

so, I start my day, boot up my laptop. Open emacs, open a web app.

cider jack in, go to my repl.clj and run reset

and boom, it fails to find some namespaces

I have to go to each namespace, and compile

then run reset, and it works

and now I can compile functions on the fly

does it run tools.namespace/refresh your reset impl?

hmmm, no only tools.namespaces/set-init!

set-init! is not part of tools.namespace

I’m using reloaded.repl

https://github.com/weavejester/reloaded.repl

ah, I might need to refer reset

indeed. it sounds like nothing runs refresh in your setup

I was under the impression that reset would do that

you should also see a list of reloaded namespaces in your repl most likely if refresh was run during reset

depends on the reset impl i guess...

hmm, well it seems to do so https://github.com/weavejester/reloaded.repl/blob/master/src/reloaded/repl.clj#L53

indeed it does. but you said you needed to require reladed.repl’s reset?! so what kind of reset did you run before requiring it?

yeah, I was requiring reset. I wasn’t requiring refresh

ah, working now Rebooting emacs for good measure

this is my repl, btw:

(ns repl
  (:require [reloaded.repl :refer [system reset stop]]
            [clojure.tools.namespace.repl :refer [refresh]]
            [qfx-export.core :as q]
            [environ.core :refer [env]]))

(def config {:client-id         (env :client-id)
             :client-secret     (env :client-secret)
             :oauth-domain      (env :oauth-domain)
             :oauth-callback    (env :oauth-callback)
             :oauth-url         (env :oauth-url)
             :oauth-profile-url (env :oauth-profile-url)
             :oauth-token-url   (env :oauth-token-url)
             :port              (env :port)})

(reloaded.repl/set-init! #(q/create-system config))

if this is reloaded.repl’s reset that should do the trick. you shouldn’t need to require refresh...

yeah, but it isn’t doing the trick

what it should do, and what it is actually doing don’t align.

can you show your project.clj? what is your source-paths and/or your dev-source-paths and where does the file live for your repl namespace?

and this is the repl.clj for this project:

(ns repl
  (:require [reloaded.repl :refer [system reset stop]]
            [clojure.tools.namespace.repl :refer [refresh]]
            [zoom-recordings.server.core :as s]
            [immuconf.config :as immuconf]))

(let [home-dir (System/getProperty "user.home")]
  (reloaded.repl/set-init! #(s/create-system (immuconf/load "resources/config.edn" 
                                                            (str home-dir "/.private/zoom-recordings/config.edn")))))

repl.clj lives under a dev dir that is a sibling of the src dir.

Example of calling (refresh :after 'reloaded.repl/resume) directly:

:reloading (zoom-recordings.server.db.setup zoom-recordings.server.s3 zoom-recordings.server.db.recordings zoom-recordings.server.routes.core zoom-recordings.server.core zoom-recordings.server.db.db-test-component repl zoom-recordings.server.db.fixtures zoom-recordings.server.db.setup-tests zoom-recordings.server.db.recordings-test)
:error-while-loading zoom-recordings.server.db.setup
#error {
 :cause "No namespace: zoom-recordings.server.db.core"
 :via
 [{:type clojure.lang.Compiler$CompilerException
   :message "java.lang.Exception: No namespace: zoom-recordings.server.db.core, compiling:(zoom_recordings/server/db/setup.clj:1:1)"
   :at [clojure.lang.Compiler load "Compiler.java" 7239]}
  {:type java.lang.Exception
   :message "No namespace: zoom-recordings.server.db.core"
   :at [clojure.core$refer doInvoke "core.clj" 4080]}]
 :trace

but it is there, and I have to go and manually compile that namespace

upgrading to 0.2.1 of reloaded.repl. I just noticed I was using 0.2.0

so I think (not 100% sure) there are two problems here: - your dev source-path points to ”dev” and according what you said your repl.clj is under "src/dev” - but more importantly repl.clj won’t get loaded automatically, user.clj would because: > You probably know that the Clojure REPL starts by default in the user namespace. In addition, if there is a file named user.clj at the root of the Java classpath, Clojure will load that file automatically when it starts.

no, it is under dev

dev is not under src

misunderstood you then

it could be the second point then

hmmm

the reason i placed it under a dev dir outside the main code, is because I don’t want it in production.

that is the good approach

so, I should just replicated the namespace inside dev ?

will try that

you should have an user.clj under dev not repl.clj i think

because user.clj would be autoloaded (see the quote above)

ah

your problem may be that your repl.clj is not autoloaded

hmmmm, changing to user.clj doesn’t work either. But I think you are right. My repl.clj or user.clj isn’t being loaded.

I’m probably placing user.clj in the wrong location

whoohooo

I got it to work after reading through clojure.tools.namespace

so, I had :main defined in my dev lein profile.

which was triggering AOT

When in doubt, it's AOT.

sorry for bothering you guys. I should have read the docs more carefully. The docs for tools that abstract tools.namespace assume we know this.

btw, @stuartsierra thank you for the Readme in tools.namespace

You're welcome! Glad to hear it was helpful.

uh, nice 👍

Hey all. I updated Cider (accidentally) to 0.10.0-SNAPSHOT. It wants an cider/cider-nrepl 0.10.0-SNAPSHOT, which I also installed, and nrepl 0.12.0 or later. I have this installed, and Leiningen sees it, but when I open a Cider repl, it still sees the old version. Can anyone help?
