I have numerous issues with boot on windows. I had this weird error that I discussed here 2 days ago saying character to be escaped missing with an IllegalArgumentException. The same thing works on an archlinux box but not on the win7 one. So I went ahead and tried to strip the code down in the files which resulted in another set of errors stating boot cannot delete some temp files. I created a minimal example here - https://github.com/xificurC/boot-windows And running boot cljs results in this - https://www.refheap.com/108755 Any tips welcome and @micha let me know if I should file an issue on GH

@xifi: there are known issues with deleting temp files on windows

the problem is that windows won't allow a file to be deleted if any process has an open filehandle to it

unlike unix

and it's common for java programmers to open InputStreams and not close them, because they get closed automatically when they go out of scope and the garbge collector runs their finalization code

who is holding a handle on a just created temp file

clojure does when it compiles a namespace for example

but it's common practice

there is a thing in JIRA about it, linked from the series of issues in the boot github

the only solution would be to find some hack to force GC

but the only hack i know of takes about 500ms

or more

how come I can delete the whole directory manually though

because i guess GC happened before you could type it

well the java process ended by then

windows 10 reportedly doesn't have this process

s/process/problem/

yeah all input streams are closed when the proecss ends of course

so you're saying I won't be able to use boot on win7?

we need a windows Hero

well don't look at me 😄

I'd burn the damn thing

neither alan nor i use windows, so it's difficult

what about docker?

I (have to) use it at work

docker works on windows right?

that's something i'd try if i was stuck with windows

that's what i do when i have to use a mac, too

we have a docker image available you can try

https://hub.docker.com/r/adzerk/boot-clj/

a quick search shows it does, but I never used it so I'd need to dig into it

and http://www.adzerk.com/blog/2015/03/using-docker-to-run-boot-from-anywhere/

apparently it installs a virtualbox VM along with some more stuff

yeah

it gives you a sane minimal unix environment in which to run itself

but you can use the one liner from the blog post to get a boot repl to see if it works

more setup, sigh. Also, I'm running into a dangerous area, we have restrictions on what we can install on our machines here. Although for dev purposes I think I'm fine

yeah i can imagine how terrifying docker is to a windows admin

who knows what incomprehensible things you might do

silly question: if I create an app with this setup and uberjar it will it run on windows?

totally

are the issues related to boot only?

yeah it has to do with how boot manages the working files

boot needs to be able to create files and hard links and move them around as it needs to

but you program doesn't have to do that

oh dear, I have to run a Hardware-Assisted Virtualization Detection Tool

last time I played around with the settings of this notebook I almost nuked it

the tech support was scratching their heads for 30 minutes

since I already have VirtualBox I can just setup my own linux VM and work from there

thanks @micha, I was hoping I wouldn't need to use a VM but oh well

if you can get docker going it's a pretty nice way to go

it feels like a normal application

lightweight

one more recurring question

any timeline on some nice hoplon docs/wiki?

yeah the app is lightweight but the VM itself adds a nice overhead

this weekend i hope to work on the transition to the new organization and reorg the repos

maybe get a new hoplon website up

basically setting things up for everyone to contribute to the wiki and docs as they wish

from there we should see the pace pick up

you're saying everyone, is there a big userbase?

I thought it's gonna be mainly you or Alan that whips out the wiki

yeah there are quite a few people using it in production

I hope they'll be generous regarding documentation

it's flying under the radar, people just use it and don't blog about it

which is i think pretty awesome

work getting done

why is it awesome when the word is not being spread?

or you meant that people use it in prod

yep

i think that makes for a solid base, real-world stuff

all I hear is react here react there

haha yeah

@alandipert said a couple days ago he thinks hoplon is better and will outlive react. Those are strong words

i agree with him

the hoplon philosophy is more like elm-lang than anything else

technically i would say that it's a web components implementation

but imo better than the google concept of web components

and of course immutable yadda dataflow yadda yadda

@micha: by the way I'd suggest changing the README on github for windows. If it's broken I'd rather see a statement like you just did, use docker or a VM. I myself lost a day trying to figure out what's causing the issues

a link to the wiki page is probably the thing there

we have a wiki page for windows

@micha: Been a while since I looked at latest hoplon/boot2 — is there a story around load time for use in hybrid mobile apps?

Probably best answered in the #C08BDAPRA channel….

hey everyone. is anyone using circleci?

i've yet to be able to get dependency caching to work

and it would massively speed up my builds and make me super happy

oh i think i might have figured it out

CircleCI should cache ~/.m2 by default

i just noticed that the cache is saved before the test command is run

so i added a call to boot show -d

in the dependencies section

which i think should fix things

@pleasetrythisathome: you might need to list manually in cache_dirs

will let you know it works, running now

@martinklepsch: Nope, m2 is automatically in cache_dirs
