trying to follow the clojurescript quick start and not getting a repl prompt. Any idea how to debug? Get the "hello world!" and the web page but that's where it stops

it goes into repl if I omit both the --main cljs.main and the --compile hello-world.core parts

@vigilancetech try to add -r at the end of the command without removing compile and main

@richiardiandrea it already has --repl at the end

https://clojurescript.org/guides/quick-start

Oh ok, in that case I would not know what's wrong then..

probably some corrupt file or library. I've reinstalled everything I can think of

other than the whole OS

@vigilancetech there are ways to debug this, try cljs --main cljs.main when the browser pops open you should look at the browser console log for errors

Also I happen to be working on a quick start doc for figwheel.main http://rigsomelight.com/figwheel-main/quick_start.html it may help you get up and running.

the document is in it's very early stages and isn't complete but you should be able to get a working REPL

Can I get om-next to normalise nested lists into its default db format? I currently have a list of persons where each has a list of contact-persons and om-next only normalises the top level person list when loading its app state.

@andreasklein I don't know the answer but there is an active #om channel

@bhauman thank you. I will ask around there. There is also a dead? #om-next channel

yeah I'm not sure of the status at all

of #om-next

question about cljs.main: i’m trying out the ghostwheel tool for the first time and I’m supposed to pass a compiler option to get it to run. is this the right way of doing it? clj --main cljs.main -co "{:ghostwheel true}" --compile tst.core --repl I’ve never passed an arbitrary compiler option to a library like this before

I’m worried I’m doing this wrong because the cljs.main web page uses it by calling directly to java rather than clj

Hi. I’m trying to jack-in clojurescript repl. it seems like it’s all working fine - it says connected at the bottom of the screen but when I try to evaluate anything, it says that I need to jack-in clojurescript repl

@lee.justin.m That's right. :thumbsup: I didn't realize arbitrary compiler parameters could be used like that, but that matches up to what the ghostwheel readme says to to.

Has anyone run across javascript like this:

exports.default = exampleFunction;
module.exports = exports['default'];

Here's an example of the output it generates. (It tried to define ['default']['default'] and then later define ['default'] as that values.)

goog.provide("module$data$prs$dev$timesheet$node_modules$inline_style_prefixer$utils$isObject");
goog.provide("module$inline_style_prefixer$utils$isObject");
var module$data$prs$dev$timesheet$node_modules$inline_style_prefixer$utils$isObject={};
module$data$prs$dev$timesheet$node_modules$inline_style_prefixer$utils$isObject["default"]["default"]=function(value){return value instanceof Object&&!Array.isArray(value)};
Object.defineProperty(module$data$prs$dev$timesheet$node_modules$inline_style_prefixer$utils$isObject["default"],"__esModule",{value:true});
module$data$prs$dev$timesheet$node_modules$inline_style_prefixer$utils$isObject["default"]=module$data$prs$dev$timesheet$node_modules$inline_style_prefixer$utils$isObject["default"]["default"]

Running ClojureScript 1.10.339

@ghopper thanks for confirming (sadly the library still doesn’t work)

those two lines of javascript don’t make sense to me. the first line is how you emulate es6 default exports in es5

the second line just seems wrong.

either way, I don’t understand why the exports object would be undefined

is the source from an npm module?

@lee.justin.m Right, it definitely seemed wrong to me. It is; I've seen it in a lot of npm module dependencies. Interestingly, I just looked up the code for the dep and it's different from what I got from npm: https://github.com/rofrischmann/inline-style-prefixer/blob/master/modules/static/createPrefixer.js vs http://ix.io/1fpl

I guess the latter is the output of babel or something.

@ghopper it might be this https://github.com/webpack/webpack/issues/706#issuecomment-71461351

It looks like there is some disagreement as how to do default exports when there is only one export

I remember @thheller talking about this but I didn’t understand the issue then 🙂

Huh, interesting. I'm only vaguely familiar with the es6 export stuff. So the problem here is that the closure compiler can't consume modules using the .default method?

I'm still not sure where the ['default']['default'] is coming from.

@lee.justin.m ClojureScript doesn’t really care what you pass, and yes that should work

@dnolen thanks. now to figure out why the library doesn’t work for me 🙂

@dnolen Alright, I'll try to find the minimum reproducible.

haven’t people been talking about being able to run gists using clj + cljs.main? i want to make this test case easily reproable without zipping up the deps.edn and source and uploading it to github. this seems like the ideal case where i could just slap it on a gist and then paste a one-liner in the issue

The deps.edn could be on the command line, no?

@ghopper the .default.default comes from Closure rewriting ES6 files that were rewritten by babel to be commonjs

which unfortunately is a won't fix in closure https://github.com/google/closure-compiler/issues/2971

@thheller Why does closure think it's ES6 if it's already been compiled to commonjs?

no, closure thinks its commonjs

Which should be fine, right? Babel already changed it from ES6 to commonjs.

no, closure does not detect the __esModule marker and since commonjs doesn't have a default export it just rewrites it like any other exported property

I'll read that issue and try to understand.

Thanks

leaving you with .default.default

@thheller Alright, so I understand the .default.default thing, I think. However, the generated output should still not throw errors, right? I should be able to manually get the default property and use it?

Is there any workaround for consuming these modules from clojurescript at the moment?

@andreasklein #om is the om.next channel - however I’m too swamped with ClojureScript stuff these days to be all that active anymore - note there are lot of alternatives these days Fulcro etc.

@bhauman it says "Uncaught SyntaxError: Invalid or unexpected token" at main.js:1 which is: "#!/usr/bin/env node"

@vigilancetech I'll need some more context as that doesn't give me much

main.js shouldn't have #!/usr/bin/env node at all

@vigilancetech what command are you using?

cljs --main cljs.main?

clj --main cljs.main

cljs isn't found

so have you created a deps.edn file and specified clojurescript as a dependency?

yes

{:deps {org.clojure/clojurescript {:mvn/version "1.10.339"}}}

oh OK I understand what you are saying now

#!/usr/bin/env node
if(typeof Math.imul == "undefined" || (Math.imul(0xffffffff,5) == 0)) {
    Math.imul = function (a, b) {
        var ah  = (a >>> 16) & 0xffff;
        var al = a & 0xffff;
        var bh  = (b >>> 16) & 0xffff;
        var bl = b & 0xffff;
        // the shift by 0 fixes the sign on the high part
        // the final |0 converts the unsigned value into a signed value
        return ((al * bl) + (((ah * bl + al * bh) << 16) >>> 0)|0);
    }
}

var path = require("path");
try {
    require("source-map-support").install();
} catch(err) {
}
require(path.join(path.resolve("."),"out","goog","bootstrap","nodejs.js"));
require(path.join(path.resolve("."),"out","cljs_deps.js"));
goog.global.CLOSURE_UNCOMPILED_DEFINES = {"cljs.core._STAR_target_STAR_":"nodejs"};
goog.require("hello_world.core");
goog.require("cljs.nodejscli");

OK you will need to delete your out directory

same error

and delete main.js

and then run clj -m cljs.main

ah, no more error 🙂 Now to see if it will fire up a repl

yes cleaning main.js and the out directory while you are trying different commands is important

still waiting on a repl

@vigilancetech the above command should start a REPL

I added a -r to the end

you don't need -r to get a REPL

in this case

but yes if you are compiling hello-world.core you would need -r as well

clj by itself gives me one. clj -m cljs.main doesn't. It gives me the parking page and just hangs

let's figure that out

it sounds like a caching issue

try it again and and open the browser console to find the error

no error

shift reload

no change

I did the compile hello_world and printed that to the term, but no repl

what command did you use?

clj -m cljs.main -c hello_world.core -r

and what printed to the terminal?

"hello world"?

Hello world!

2x cuz of the reload

but no REPL?

nope

where did it print? in the console or the terminal?

term

that means a repl connection was made

do you not see a cljs.user=> in the terminal?

no

enter in the terminal just gives blank lines

try this

enter "1"

and hit enter

nothing

the 1 echoed when I typed it, but nothing came back

What OS and shell are you using?

bash and the latest sabayon

and what browser?

had to look up sabayon, man one of these days they are simply going to run out of names for linux distros

chromium

lol, yeah, well, its been around for while. Well know to gentooists

I used gentoo way way back when it started

I was on it for a long time, but I got tired of compiling. Sabayon gives you the best of both

understandable, OK let's try something different

but I want to move to guixSD cuz I'm sick of collisions/corruption like's most likely causing this

yeah, it sounds like its connected

We could quickly try a different tack, and try figwheel.main

it has better feedback mechanisms to help track down problems

put it in the deps.edn?

just use that as your deps.edn file

perhaps in a different fresh directory

let's just try to get a REPL

by running clojure -m figwheel.main

I think it doesn't like my hostname. My /etc/hostname only has this machine's name and not the domain. Exception in thread "Thread-1" java.net.UnknownHostException: scuttle: scuttle: Name or service not known

still no repl

@vigilancetech well that sucks

I have systemd. IIRC that handles it somehow

obviously *mis*handling in this case 🙂

probably quickest way to get this is to reboot, brb

I think that is a bug on my end

if you get it again you should see figwheel.main.cljc line 933 in the stacktrace

the error message is gone but still no repl (using the same code)

with figwheel.main?

I deleted my bhauman folder out of .m2/repository and re-ran the command

what output do you get?

does it look like a REPL is trying to start

Exception in thread "main" java.io.FileNotFoundException: Could not locate figwheel/main__init.class or figwheel/main.clj on classpath.

drops back to the $ prompt

OK delete your .cpcache

in your current directory

since you deleted stuff from the repo

your .cpcache is preventing the deps from being refetched

I think I just fixed the java.net.UnknownHostException

IT WORKED!!! Thanks! BTW, I really liked your "Developing ClojureScript With Figwheel" 2015 speech. You should try some open-mic nite stand-up comedy 😄

will I get that version by just deleting your stuff in the .m2?

not yet 🙂

I'll release a snapshot soon

I'm glad its working

so basically my main problem was cuz my host(s) weren't set up properly (and maybe your code wasn't handling it elegantly)?

yeah I just pushed a commit

https://github.com/bhauman/figwheel-main

and you can also learn more about figwheel-main there

👍 Thanks again! I have a big deadline monday eve. This will help A LOT!

and there is a #figwheel-main channel

jesus!

good luck

thx! Looking forward to using this

yeah in the helper app that pops up it tells you how to create a "build"

well I wish you luck!

can I compose anync use-fixtures? the ones with :before and :after. Can they be compose-fixtures-ed?

oh, I am reading "NOTE: Incompatible with map fixtures." in the doc
