[ClojureScript] Re: Classpath bug re Clojure 1.10.1.645 when using Figwheel.Main

[Alan Thompson]

P.S.  There seems to be no *`clojure --version`* flag.  Should this be
added to the command line tool?

[ClojureScript] Classpath bug re Clojure 1.10.1.645 when using Figwheel.Main

[Alan Thompson]

Hi.  Just helped a colleague debug a vexing problem on a CLJS project using
Figwheel.Main.

If we do *`brew install clojure/tools/clojure`*, it works:

~/work/tmp810/xanadu > clj --help
Version: *1.10.1.561*

Usage: clojure [dep-opt*] [--] [init-opt*] [main-opt] [arg*]
   clj [dep-opt*] [--] [init-opt*] [main-opt] [arg*]

The clojure script is a runner for Clojure. clj is a wrapper
for interactive repl use. These scripts ultimately construct and



Note that local ./resources etc are at the beginning of the classpath

[ClojureScript] Figwheel.Main error trying to open cljs reload socket

[Alan Thompson]

Using figwheel-main, I am getting a strange error:

Figwheel: trying to open cljs reload socket
socket.cljs:71
WebSocket connection to 'ws://localhost:3449/figwheel-ws' failed:
Error in connection establishment: net::ERR_CONNECTION_REFUSED


As the error message implies, hot reloading doesn't work w/o the socket.
Any clues on what could be causing this?

Re: [ClojureScript] figwheel-main vs headless chrome testing

[Alan Thompson]

Hi - Here is a template project that I've developed to showcase CLJS
testing and JS interop & testing.  Just clone this repo:

https://github.com/cloojure/cljs-template.git



and follow the README to set up cljs tests (`lein test` for CLJ will work
out of the box).

It is based on the original figwheel (plans to upgrade to figwheel-main are
in the works).

[ClojureScript] Figwheel build failure for CLJS 1.10.516: Error: Cannot find module '@cljs-oss/module-deps'

[Alan Thompson]

Hi - I have a re-frame app that works fine for CLJS 1.10.439, but fails in
compile for CLJS 1.10.516.  Any suggestions?

Here is the working and failing build output for `lein figwheel`:

Re: [ClojureScript] Clojurescript testing

This setup includes the ability to use/test native JS libs in 3 different
ways, which required a bit of a struggle (i.e. trial & error) to get the
syntax right.  Here are the native JavaScript files in ~/resources:

Re: [ClojureScript] Clojurescript testing

[Alan Thompson]

I have a nice setup for CLJS testing using the `doo` test framework.  It
can run tests either at the command line using `phantomjs` or in the
browser (eg Chrome).  It has source and test dirs segregrated into `clj`,
`cljc`, and `cljs` subdirs so you can get macros and dual-use code working
correctly.  You can see it here:

https://github.com/cloojure/cljs-template

A sample run:


~/expr/cljs-template > lein clean ; time lein doo phantom test once

;; ==
;; Testing with Phantom:

doorunner - beginning
doorunner - end

Testing tst.flintstones.dino
test once - enter
globalObject:   #js {:a 1, :b 2, :c 3}
(-> % .-b (+ 5) => 7
(js/makeDino) => #js {:desc blue dino-dog, :says #object[Function]}
dino.desc =>  blue dino-dog
dino.says(5) =>  Ruff-Ruff-Ruff-Ruff-Ruff!
:keep-words ("am" "having" "today")
:re-seq ("am" "having" "today")
test once - leave

Testing tst.flintstones.wilma
test each - enter
test each - leave
test each - enter
wilmaPhony/stats:#js {:lipstick red, :height 5.5}
wilma => #js {:desc patient housewife, :says #object[Function]}
test each - leave

Testing tst.flintstones.pebbles

[ClojureScript] Re: Plumatic Schema error in CLJS

[Alan Thompson]

I wrote up more details of this error on StackOverflow:

https://stackoverflow.com/questions/53149344/what-causes-error-no-protocol-method-xxx-yyy-defined-for-type-undefined-in-clo


These errors are particularly insidious since the error message is so
vague, and there was no reference to the offending file & line. In face, in
this case it was caused by a chain of references across 4 files:

tst.tupelo.core -> tupelo.core -> tupelo.impl -> tupelo.schema

[ClojureScript] Re: Plumatic Schema error in CLJS

[Alan Thompson]

OK, I found the cause of the error.  In a dependent namespace, I had
defined some schemas:

(ns tupelo.schema
  "Prismatic Schema type definitions"
  (:require [schema.core :as s])
  #?(:clj (:import [java.util HashSet] ))
  #?(:clj (:gen-class)))

(def Set
  "Either a Clojure hash-set or a java.util.HashSet"
  (s/either #{s/Any}
*#?(:clj* java.util.HashSet*)*))  ; <= *This was missing the
#?(:clj ...)*   and caused the error

[ClojureScript] Plumatic Schema error in CLJS

[Alan Thompson]

Copied from the Clojure mailing list


I am seeing the following errors in CLJS, but not in CLJ:

ERROR in (dotest-line-695) (schema/core.js:33:64)
expected: (clojure.core/= (t/thru 9) (t/glue-rows data))
  actual: #object[Error Error: No protocol method Schema.spec defined for
type undefined: ]


The errors disappear if I remove Plumatic Schema elements of the function
definition:

; this one produces the error in clojurescript (clojure runs fine)
(s/defn glue-rows  :- tsk/List
  [coll-2d :- tsk/List]
...

; this one works fine in both clojure and clojurescript
(s/defn glue-rows  :- tsk/List
  [coll-2d :- tsk/List]
...


Any clues as to the cause of this behavior?
Alan

Hi - Just learned about the Martian project this week.  It sounds exactly
like what you need.  I'm looking forward to using it in future projects.

I have tested that it works on Java 10 now using Figwheel 0.5.16.My

Re: [ClojureScript] Re: Figwheel and Java 9 compatibility

[Alan Thompson]

I just tried it with Java 10.  I get the same error as for Java 9, and it
has the same fix:

  :jvm-opts ["-Xmx1g" "--add-modules" "java.xml.bind"])


This is with

  :dependencies [[org.clojure/clojure "1.9.0"]
 [org.clojure/clojurescript "1.10.238"] ]
  :plugins [[lein-cljsbuild "1.1.7" :exclusions [[org.clojure/clojure]]]
[lein-figwheel "0.5.15"] ]


So one of those dependencies is still not cool with java 9/10.

Clojure itself works fine on Java 10 (just tested).

The stacktrace mentiones both http-kit and
figwheel-sidecar/figwheel-server not sure who the culprit is (or
clojurescript 1.10.238 ?)

Re: [ClojureScript] Re: Figwheel and Java 9 compatibility

That looks good.  Can you verify it matches what is in `project.clj`?
Also, try `lein --version` or type `lein repl` to verify the same stuff is
found.

Can you verify versions for Java, Clojure, & ClojureScript?

[ClojureScript] GMail code formatter

[Alan Thompson]

Just discovered a cool Chrome extension so that you can get proper syntax
highlighting when pasting code into your email.  It turns plain-old code
into something nice to read:

*Plain:*

(defn truthy?
  "Returns true if arg is logical true (neither nil nor false); otherwise
returns false."
  [arg]
  (if arg true false) )
(s/fdef truthy?
  :args ::s/any
  :ret boolean?)

*Nice:*


(defn truthy?
  "Returns true if arg is logical true (neither nil nor false); otherwise
returns false."
  [arg]
  (if arg true false) )
(s/fdef truthy?
  :args ::s/any
  :ret boolean?)


Find it in the Google Chrome web store:

[ClojureScript] Omission on ClojureScript Quick-Start on GH

[Alan Thompson]

Hi - Anybody here familiar with the CLJS QuickStart on github?   I think
I've found an omission.  At the part about adding foo:

(defn foo [a b]
  (+ a b))


it is missing the ":reload" in the (require ...).  The missing ":reload"
results in this at the repl:

cljs.user=> (require '[hello-world.core :as hello] )
nil
cljs.user=> (hello/foo 2 3)
TypeError: Cannot read property 'call' of undefined
(NO_SOURCE_FILE)


The ":reload" is present in the 2nd part for


(defn foo [a b]
  (* a b)) ;; CHANGED


I think we need a small update to the README.  Should I submit a PR?
