dirac + cljs-repl max call stack exceeded?

[torgeir]

Do feel free to shoot this down if this is not an issue with dirac, rather some of the other dependencies, a combination, or a too complex setup to dig into 😄

In an attempt to see how good of a cljs stack I could come up with, I was trying out dirac in combination with a few other tools along with boot; dirac, boot-cljs-devtools, boot-cljs-repl, boot-cljs, boot-http, boot-reload

This branch holds a repro https://github.com/torgeir/gen-cljs/tree/dirac-start-browser-repl-max-call-stack-exceeded.

What I'm seeing is by running boot dev (after adding (dirac)) to fire everything up, and connecting to it in another terminal window with boot repl -c - it connects nicely

The repl still seems to be working

but the dirac console also complains

Is this a problem? I don't know. The issue I am having with it is that my emacs instance is no longer able to run cider-connect followed by (start-repl) and have a working repl inside emacs to evaluate cljs code on the go.

---

I am running boot with the following ~/.boot/profile.boot in place to have things working inside emacs.

(def v-tools-nrepl "0.2.13")
(def v-cider-nrepl "0.17.0-SNAPSHOT")
(def v-refactor-nrepl "2.4.0-SNAPSHOT")

(deftask cider "CIDER profile"
  []
  (require 'boot.repl)
  (swap! @(resolve 'boot.repl/*default-dependencies*)
         concat `[[org.clojure/tools.nrepl ~v-tools-nrepl]
                  [cider/cider-nrepl ~v-cider-nrepl]
                  [~'refactor-nrepl ~v-refactor-nrepl]
                  ])
  (swap! @(resolve 'boot.repl/*default-middleware*)
         concat '[cider.nrepl/cider-middleware
                  refactor-nrepl.middleware/wrap-refactor
                  ])
  identity)

Without (dirac) in place in the boot dev task, substituting the boot dev mentioned above with boot cider dev and running cider-connect followed by (start-repl) seems to be working nicely and allows me to eval cljs from the emacs instance.

Edit:
With these versions of boot and clojure, on java 9

cat ~/.boot/boot.properties
#http://boot-clj.com
#Fri Jan 26 21:08:58 CET 2018
BOOT_VERSION=2.8.0-SNAPSHOT
BOOT_CLOJURE_VERSION=1.9.0
BOOT_CLOJURE_NAME=org.clojure/clojure

[darwin]

I tried to reproduce it on my macOS 10.13 machine and it works for me.

Used java9, all your files including ~/.boot/profile.boot, but my boot is 2.7.2:

cat ~/.boot/boot.properties
#http://boot-clj.com
#Sat Jan 27 22:38:14 CET 2018
BOOT_CLOJURE_NAME=org.clojure/clojure
BOOT_CLOJURE_VERSION=1.9.0
BOOT_VERSION=2.7.2

Have you tried to remove whole ~/.boot and start from scratch? Yesterday I had quite weird issues with boot until doing that. Details in the #dirac slack channel.

I'm seeing this error too running Clojure 1.9.0 and boot 2.8.1.
