#hoplon

Hi, I'm trying to use boot-hoplon task in new boot to compile hoplon, but it seems it works bit differently than previous hoplon task - it doesnt touch cljs files, it is only focusing on hoplon. Will this change ? or it will be responsibility of programmer to composer cljs task and hoplon ?

voytech: hello there! and welcome!

Hi !

voytech: yes, the user will compose them

but we'll have a pre-rolled solution too, a task that has them composed already

that you can use if your requirements are relatively standard

but you can still decompose them yourself if you have requirements that are not supported by the pre-roll solution

does that make sense?

more flexible

michaniskin: I've one more question, because I have problems today with compiling hoplon - resulted html was almost empty no body at all, only script with following src index.html.js ? it is normal behaviour or am I missing something...

voytech: that sounds normal - there won’t be any actual HTML source unless you prerender. normally hoplon will generate the dom on load as it evaluates your hlisp

Hello, just noticed that hoplon 6 / boot 2 is the default branch now on github.

Congrats!!

but that is great! ul_ has been doing incredible work

it blows my mind that he ported it to boot2 as a matter of trying it

wow

good work ul_

we are entering an amazing era, for sure

i'm excited

i have a toy project that uses 4 compilers in sequence, continuously

wat?

antlr, javac, clojure, kawa scheme, all in a build pipeline

wow

i type and it all compilse and runs

err, “boot antlr -p simplisp -v javac watch yeti run -m simplisp.Main -a "(+ 1 2)””

so the parser compiles first and then yeti compiles continuously

but yeah the effort put into shaving all the frontend yaks definitely seems to pay for backend/server things; basically any polyglot scenario is amazing in boot

haha what is that i don't even

yeti?

an obscure ML dialect for the jvm written by a reclusive swedish genius

ooh

might have to bring that to the next functional programming night here in Brighton

danielneal: https://github.com/alandipert/boot-yeti

is ul_ around? or michaniskin? I have a question...

danielneal: there has been a bunch of discussion about this recently, https://botbot.me/freenode/hoplon/search/?q=inc... /cc raywillig martinklepsch ^^

aha thanks will have a read through

danielneal: you are completely right about moving vendor to cljsjs. what about contrib is better to ask michaniskin or alandipert, it is completely voluntary decision — to add contrib dir into repo or deploy contrib libs in arbitrary repos & namespaces

i kind of like the idea of a hoplon-sanctioned contrib repo, if only because the shape of a contrib API surface would be guided by hoplon design idioms. we could keep things in one place that will work nicely in a hoplon app. e.g. cell-aware

is there a cljson implementation directly in javascript?

onetom__: cognitect's transit

it's the same thing, they implemented it in hand optimized JS

im just wondering if i could start "rotting" our previous node api server from inside and hook it up to castra servers

we might be ready to switch from cljson to transit anyway

another option is david nolen’s mori, a build of the cljs runtime you can drive from JS

why switch? transit is more compact?

or because it's better supported?

the big difference is non-cljs, non-clj interop went into the design

so they have ruby, erlang, etc transit libs

we only care about clj/s because that’s all you need :-)

for new applications...

but to rejuvenate applications, the transition period has to be supported... :/

alandipert - yeah having rubber stamped contrib in one place would be good for discovering what is possible and consistency

onetom: https://github.com/tailrecursion/mori is a fork of mori i did last year that includes javelin

onetom: you could modify it a little more to include cljson if you wanted

alandipert: thx

the primary downside to that over transit is you incur cljs runtime overhead (which you wouldn’t with transit)

onetom__: https://github.com/tailrecursion/mori/commit/c2... has the details

i was thinking about swapping out old nodejs backend code which talked to the database with new castra backend code which talks to datomic

castra should be able to support transit btw

there is a multimethod that lets you swap out cljson with anything else

maybe it’s time for transit to be the default?

yeah i haven't used it either yet

does it support everything cljson does now?

sure, everything is possible. i actually tried to modify that multimethod and it worked.

my question really was just trying to avoid duplicate effort

i use transit as packer with sente

seems to be working fine

alandipert: >60 ppl on chan )))

:)

wow maybe 2015 will see a HopConf?

I'm there!

@ul_ @alandipert i'm just starting out on using boot2... i'm getting an error: No such var: core/add-meta something to do with boot-cljs?

any ideas ?

danielneal: boot -u? sounds like you’re on an older boot

i was already asked to give a talk about hoplon at https://generalassemb.ly

or may be you have meta in your page

ooh

in hoplon6 you should use html-mets

html-meta

thanks @alandipert... boot -u seems to be doing some magic

danielneal: add-meta is a neat function in recent boot, tasks can add metadata to files in the fileset. for instance a compiler might put error messages in some file as metadata on the file with the problems

@onetom___ that' cool - do you know when that would be? would love to come

@onetom____ there's some magic stuff you can do with hoplon + reveal ;)

hasnt been fixed yet

danielneal: r u in hk?

brighton

, uk

aha - i thought the talk would be in london ;) didn't realize you were in hk!

yeah, i live on lamma island. very nice combo. the metropolis is just half hour ferry ride away

on the island we have nice beaches; i was just invited to this year's 1st hungarian dragon boat exercise tomorrow morning, so good nite for now

wow, have fun!

@ul_ just a question - trying to get hoplon.io working for starters, i'm getting Could not find artifact org.clojure:clojurescript:jar:0.0.0

do i have to specify a clojurescript version somewhere?

hmm... let me try by my own, i didn't after ltest changes by michaniskin

oh wait, my bad - i'd upgraded the cljsjs dependency

trying to fix a different problem

the only thing is it needs hoplon 0.1.0 is not found - only snapshot dependency is there

yes, thank you for pointing, fixed deps in repo

boot-cljs should work 2814-0

2814-1 is broken is clojurescript not explicitely specified

we should move all of this to stabilized/clojurescript i think

i'm going to add :exclusions to boot today

so you can :exclude org.clojure/clojurescript

michaniskin: how do you think, what will be good example to attach to vfsm lib?

not huge, but explanatory and, may be, involving watching cells

may be some ui depending on possibly failing network request?
