hey, can we get a gitignore on .nrepl-history?

not sure what repo that should go against

how do you mean?

a file called .nrepl-history is showing up in git as unstaged

looks like something that should be ignored

you can make a .gitignore file in your project directory

yeah i can

.nrepl-*

i’m suggesting that one is shipped with the project

which project?

the one that gets auto generated

ah yeah

in fact there is one

`/.boot/ /.nrepl-port /.repl-history /.lein-* /target /classes /checkouts `

/.boot/
/.nrepl-port
/.repl-history
/.lein-*
/target
/classes
/checkouts

and it doesn’t contain .nrepl-history

it's the lein-hoplon repo i think

ok, so, say i write a little re-usable component element thing with hoplon in a hl file

what might be a good way to test it?

there is a library, cljs.test that you can use

it's part of the cljs core distribution

you don't need any extra dependencies for it

ah cool, i’ll have a look

thanks

@micha: hey, i’m noobing out with your heroku deployment example

i haven't looked at that in a while

oh ok

is there a different heroku example?

i’m just wondering what :main-class is supposed to be

i don't really remember what i did with heroku, it was pretty long time ago

i think there is a boot build pack for heroku now

oh sure

let me google what that means 😛

so, originally i ran

lein new hoplon-castra my-project-name

but i did not get a project.clj file

is that right?

that sounds correct

you should have a build.boot file though

i do

but heroku rejects my pushes because of the missing project.clj file

that's what the buildpacks are for

the boot one uses boot instead of leiningen

so it doesn't complain if you don't have a project.clj

but maybe you can make a bogus one just to shut heroku up and let you compute

i think it's just trying to be helpful

and it doesn't really need it

is this what you’re talking about?

https://github.com/upworthy/heroku-buildpack-boot

yes, i think so

hmm, ok

taking a step back

i run boot prod

i don’t get any .jar

is that right?

hmm, getting further along

the buildpack did something...

any idea what

desc="No web processes running

means for heroku?

nm, think i found it

Error: Could not find or load main class clojure.main

now

man...

i sort of got it working with

(serve …) (hoplon) (reload) (cljs) (wait)

but (cljs :optimizations :advanced) seemed to freak out the free dyno on heroku because of memory

trying to get it working with a war file

anyone know what Set the 'serve' callback function to SYM. means for boot web?

@alandipert: i have a suggestion for https://github.com/hoplon/hoplon/wiki/Get-Started

actually show how to get something deployed somewhere

"A deftask form that creates a prod task. We would use this to compile the project for deployment."

that has not really helped me so far

it would be great to show a basic deployment to a free service like heroku for the demo app

hi

can anyone tell me what i’m supposed to set serve as in boot web in the hoplon/castra template to get a war file working?

ok, a different question...

if i do

(serve …)
(hoplon)
(cljs)
(wait)

i get a page

if i do

(hoplon)
(cljs)

in one boot task

and

(serve …)
(wait)

in a different one just afterwards

i get a response from the server, but it’s a WSOD

what’s going on there?

@thedavidmeister: are you serving from filesystem or classpath?

(serve :dir "./target" :port 3000 :handler 'my-app.handler/app)

is what i’m trying

so i guess the filesystem?

not sure how to tell

@martinklepsch: ^^

@thedavidmeister: it’s generally easier in my experience to just serve from classpath, I think that would be just (serve :port ….)

so drop the :dir?

@martinklepsch: the problem is i get this

Oct 25 07:07:37 estimate-work app/web.1:  Compiling ClojureScript... 
Oct 25 07:07:37 estimate-work app/web.1:  Adding :require adzerk.boot-reload to index.html.cljs.edn... 
Oct 25 07:07:37 estimate-work app/web.1:  • index.html.js

Oct 25 07:07:40 estimate-work heroku/web.1:  Error R14 (Memory quota exceeded) 

I assume it’s the compiling using all that memory

and that a minimum hoplon/castra setup does not consume over 500mb

so I’m trying to get all the compiling done either when I push to heroku or on my local

and then just serve from heroku

Are you setting appropriate JVM options so that used memory does not surpass heroku’s limits?

i assume not

i just did this:

web: boot heroku-serve -p $PORT

(deftask heroku-serve
  [p port PORT int "The port to serve on"]
  (comp
    (serve :port port :handler 'my-app.handler/app)
    (hoplon)
    (reload)
    (cljs :optimizations :whitespace)
    (wait)
  )
)

in the procfile and build.boot respectively

how would I set JVM options?

via environment variables

check the boot wiki for details

https://github.com/boot-clj/boot/wiki/Configuring-Boot

and https://github.com/boot-clj/boot/wiki/JVM-Options

ah cool

heroku sends jvm options doesn’t it?

@martinklepsch: regardless, i only get the errors when i try to serve, not during the build

@martinklepsch: is there a reason why i need to compile after serving to see my work?

@martinklepsch: if i already generated a target folder, why can’t I just run (serve) (wait)?

if you serve from the filesystem you can do that

right, and that’s what dir does?

@thedavidmeister: all tasks have built in documentation you can view with boot task -h, e.g. boot serve -h

yeah, i’ve read it all like 10x

it’s a bit cryptic and terse for me

oh ok. so :dir is how you can specify a directory to serve from like target/

yeah

let me try one more time, now that you’ve said it

(deftask make-thing
  []
  (comp
    (hoplon)
    (cljs)
  )
)

(deftask serve-thing
  []
  (comp
    (serve :dir "target/" :port 3000 :handler 'my-app.handler/app)
    (wait)
  )
)

then

$ boot make-thing; boot serve-thing

i see

2015-10-26 01:30:24.064:INFO:oejs.Server:jetty-7.6.13.v20130916
2015-10-26 01:30:24.120:INFO:oejs.AbstractConnector:Started [email protected]:3000
<< started Jetty on http://localhost:3000 >>

in terminal

but when i go there in chrome, i just get a WSOD

oh… I see now. you can’t use :handler and :dir at the same time

o

if you specify a handler that handler has to take care of serving static resources.

rightio

so this looks better

no more WSOD

but

my random number updating does not work

so something in castra is nqr

@martinklepsch: is :handler able to do things that :dir cannot?

oh yay, :dir is working on heroku too

but no castra love on heroku or local 😞

@martinklepsch: well, thanks for helping. I have to get some sleep, it’s 2am here

@thedavidmeister: castra works via ring handlers so you’ll need to use :handlers and not :dir if you want to use castra

@martinklepsch: ah, ok. good to know.

@martinklepsch: so basically i just have to figure out the memory thing

@martinklepsch: if i figure out how to make a war file, will that allow castra to work without me needing to compile things on a dyno?

I’m sorry I got no clue about that

np

well, thanks again for helping

i guess i’ll try again tomorrow

@thedavidmeister: good point about deploying... maybe deploying a war to heroku is better, and then doing the cljs compile locally

Hey guys. What’s the intent of the HLisp section of the documentation? Is the intention to list all the supported HTML tags? Is it intended to teach users the general pattern of HLisp usage as in (tag :attr attr-value :attr2 attr-value2 children) ? Perhaps I could help flesh this out.

levitanong: maybe the html2cljs task from boot-hoplon belongs to that topic too, since that's the one which can convert html 2 hlisp

but i think you should write whatever you feel appropriate and afterwards we can move it around

@onetom: Okay, I’ll give it a shot.

Thanks for the advice!
