Clojurians Log v2

@viebel hey

I've eliminated all ^:const metadata temporarily

but now the repl pretty much freezes when I tried to load my ns 😕

Freezes forever?

it seems so

😢

I've been waiting for minutes in both a chrome and an edge tab

Nothing printed in the console?

only 404 GET requests

after the initial klipse related stuff

Try to add verbose=1 url param

also, the timing on those requests is strange:

Can u send me the url for your code in klipse repl?

this just in:

this is my url: http://app.klipse.tech/?external-libs=[https://raw.githubusercontent.com/moxaj/mikron/master/src/cljc]&verbose=1

If you press ctr-s you will get a url that contains your source code

(the error you got is ok. No clojure. Spec but cljs.spec The compiler tries clojure.spec and then cljs.spec)

meh, cannot copy from the alert

this is all I enter: (ns mikron.codox (:require [clojure.core]))

oh

mikron.core

i'll edit

I think it is also on the console

And also you can do ctrl-r

http://app.klipse.tech/?cljs_in=(ns%20mikron.codox%20(%3Arequire%20%5Bmikron.core%5D))&external-libs=%5Bhttps%3A%2F%2Fraw.githubusercontent.com%2Fmoxaj%2Fmikron%2Fmaster%2Fsrc%2Fcljc%5D&verbose=1

Thx

wait, still requires clojure.core

edited my link

There is an infinite loop

Loading mikron.compile-util macros namespace

Any idea why?

I think that this is the problem

(ns mikron.compile-util
  "Compile time utility functions."
  #?(:cljs (:require-macros [mikron.compile-util])))

oh well, didn't know that fails on self hosted 😮

In self-host cljs, reader conditionals always branch to :cljs

I think regular cljs will use that branch as well

No

because when you require-macros in regular cljs, it will branch to :clj

but the require-macros is inside the reader conditional

when the reader selects the branch, I don't think it cares what's inside of it

You’re right

What I meant is a bit different

but still YOU are right, since apparently this does not work in self hosted

1. (require mikron.compile-util) => loads the code with :cljs branch

2. in the :cljs branch there is a (:require-macros [mikron.compile-util])

3. (:require-macros [mikron.compile-util]) => loads the code with :clj branch in regular clojure and :cljs branch in self-host

makes sense?

yeah, it seems like a circular dep, but it works in regular cljs

because require-macros in regular cljs takes the :clj branch

I guess that makes an entry for your list of differences

between regular and self hosted

You’re welcome to add it

🙂

I think that the simples solution is to use a namespace with a slighly different name for the macros

something like mikron.compile-util.macros

and put it in a .clj file with no reader conditionals

This is the trick that is done in cljs.spec and cljs.core.async I think

And also this might help: https://github.com/cgrand/macrovich

(Actually there is a word about it in the wiki page: https://github.com/viebel/klipse/wiki/How-to-make-a-clojure-library-self-host-compatible#reader-conditionals

But I agree with you that should be more emphasized

Feel free to edit the wiki page to make it 100% clear

updated the page, take a look

Thx

I would even say explicitely that it will cause an infinite loop

alright

also, another option would be to use :require-macros and ditch this trick

what do u mean?

if I remove the self-`require-macros` and use require-macros explicitly in the dependent namespaces, it would work

that sounds like a good idea

I already have a few separate -macro namespaces, but that's only for the case when I'd like to use a macro in the same namespace (which I cannot do)

@viebel let me ask, does klipse use lumo < 1.1 or clojurescript < 1.9.456 for the compilation?

klipse uses lumo 1.1.0 for generating the analysis cache

at least this is how it is supposed to be

but maybe a couple of namespaces have not been properly recompiled

when I upgraded lumo

Why are u asking this question?

just had a discussion in the cljs channel

turns out the self-require trick works after all

but it failed for me with lumo < 1.1

so now i'll load my project in lumo, and if it works, then you are probably using outdated deps

if it doesn't work, then I screwed up somewhere else 😄

I cannot wait...

But I have to go to sleep now

Feel free to write all your discoveries in this channel

alright, I hope i'm not bothering you too much

I’ll read them - with pleasure - when I wake up

Not at all @moxaj

I’m really happy that you don’t give up on the way to make your (cool) lib self-host compatible

When you’ll be done you will be very happy

@viebel it works!

Hey @moxaj

I’ve deployed a fix to clojure.spec just now

Please make sure you get klipse version 6.6.2
