Hey All. I'm trying to figure out how to use environ and boot together. I whipped up a repo that demonstrates what I expected to work with a test that fails. Could I get some help to make the test pass please? Cheers

Here's the repo: https://github.com/cddr/boot-env-test

cddr: boot-test runs your tests in a pod

that could be the issue

Hm ok, so how do other folks specify different environment variables for different profiles? Or is that just a railsism that I haven't gotten over yet.

@micha: i had a go at a change log file: https://github.com/boot-clj/boot/pull/261/files

@micha: only included stuff since 2.1.2 for now... let me know if you want something like this, how to improve etc

regarding the links — doesn’t github figure this out itself usually?

or is that just in issues?

yeah, looks like it's only in issues/PRs/commits and other select places

@ragge: linking to the changelog from the README is probably a good idea

@martinklepsch: yeah, I agree

hm. seems you really need to make proper links 😕

@martinklepsch: would be good to hear if a changelog file is the way to go at all

I think it’s great.

Readme is pretty full with stuff anyways.

also thought about a division similar to clojure, separating new features, enhancements and bugfixes... but seemed overkill for now

distinction was not obvious too

yeah, I was wondering if it might make sense to split between changes in boot and it’s built-in tasks

yeah, that too

Changelog file is the way I think

punted on the whole thing and left it to the mind of the reader

but at the same time anything going forward is good. we don’t need to overdo it for a first version

@ragge: did micha add you to the boot org?

I use github releases for some projects but I think it's easier to just use a file

@martinklepsch: i don't think so, he asked about my id

@ragge: I think he asked with the intention to add you

@ragge added you

@martinklepsch: ok, cheers... was wondering if he reported me as a bot or something when nothing happened 😉

@martinklepsch: Added link to changes in readme. Train journey soon over, online again tomorrow...

@ragge: sweet

later then!

@ragge: thanks for the changelog! i’m pushing 2.2.0 today

I am trying to package Chart.js using boot-cljsjs, however, I am getting this error:

clojure.lang.ExceptionInfo: java.lang.AssertionError: Assert failed: No .ext.js file(s) found! (first externs)

@kenny: do you have a file at resources/cljsjs/chart/common/chart.ext.js?

@kenny: the packaging tasks complains because there is no externs file or it can’t find it

@martinklepsch: Why do I need to include that if it downloading it from GitHub?

@kenny: do you know what externs are and what they’re needed for?

https://github.com/cljsjs/packages/wiki

@martinklepsch: Ah. That makes sense. Thank you!

@kenny: great 👍 let me know if you have more questions

@martinklepsch: Do you know how you would declare a constructor for a subtype (e.g Foo(a).Bar(b))?

Foo = function (a) {};
Foo.Bar = function(b) {};

@kenny: not sure myself but I think the firebase externs have something like that and are well-done

maybe that helps

Will check it out. Thanks!

The reason for this seems to be passing :as-jars true to the uber task 😕

trying to figure out how to change the server port with tenzing: https://github.com/martinklepsch/tenzing , I followed code down to a serve deftask in boot-http, but don't know where to go from there: https://github.com/pandeiro/boot-http/blob/master/src/pandeiro/boot_http.clj#L33 What am I missing?

@gtrak: you can set task options using task-options!, e.g. (task-options! serve {:port 23423})

wooot, thanks!

somehow this was non-obvious

It’s in the README, although a bit further down: https://github.com/boot-clj/boot#configure-task-options

ahh, is there also a way to grab it from a boot.properties property?

got the repl running though, awesome, that was pretty easy.

gtrak: boot.properties is only meant to specify things that must be read before loading boot/clojure. so no

@gtrak: is there a reason you don’t want to put the task-options! call into build.boot?

no, that's fine, just trying to figure out the mental model

i've just worked with boot for small scripts, this is my first foray into the more complex stuff

@alandipert: thanks for taking time for a release! just noticed my link to the change log in README.md is broken because incorrect case. happy for me to commit a fix to master? @martinklepsch added me to organization

:thumbsup:

that would be awesome

done-diddly-doo

excellent!

https://github.com/boot-clj/boot/issues/264 — @ragge / @micha any quick ideas?

@martinklepsch: are you making a war file?

it looks like you're making a regular uberjar there

@micha: no, jar. see https://github.com/martinklepsch/minimal-uberjar-case/blob/master/build.boot

ok yeah

so the :as-jars option is mostly useful for war files

oh

in a war file you can put jar files inside the war under WEB-INF/lib/ and the servlet container will add them to the class path

so you don't need to fully explode the dependencies to add them to the classpath as you do with uberjar

yeah makes sense

alan was working on a classloader solution that could produce an oberjar that used jars inside the uberjar

i think he was using it for spark or hadoop

should I add some (war-only) things to the task docstrings/option docs?

@martinklepsch: perhaps some mention, but it's not specific to WAR files really

that's just the use case that i have for it

the uber task doesn't do anything WAR specific or anything

I catched something that it’s faster because it doesn’t do the exploding and thought I could just use it, running straight into an open knife 😛

had to step out for a bit, working on release again

yeah some kind of note would be good there

@martinklepsch: ^^

Cool, will try to come up with something

Error while extracting /Users/martin/.m2/repository/org/apache/tomcat/tomcat-juli/7.0.27/tomcat-juli-7.0.27.jar:META-INF/LICENSE: java.io.FileNotFoundException: /Users/martin/.boot/cache/tmp/Users/martin/projects/gridacus/solglas/nkq/dvwsf6/META-INF/LICENSE (Is a directory)

@martinklepsch: https://github.com/adzerk-oss/boot-ubermain is the experiment i did

getting plenty of these when not doing :as-jars true — is the right way around that to exclude them by adding some thing like #\"(?i)^META-INF/LICENSE$\” to excludes?

@martinklepsch: the thing it doesn’t do is provide a working boot runtime environment (nothing in boot.pod works if program launched via ubermain)

@martinklepsch: the plan in a future release is to open up some of the java setup methods in boot.App so that the boot runtime can be initialized by containers other than just the boot.sh cli

I like the usage notes

@martinklepsch: we should be handling that case i think, where you have both a file and a directory with the same path in a jar

lol why would someone do that, i have no idea

@micha: I get that printed like a lot of times — all caused by one jar having a LICENSE directory?

yeah i think so

an interesting situation to be sure

this is the problem with non-namespaced things in JARs, basically

the uber task should handle this by preferring the directory i think

and ignoring the file

@micha “When using as-jars you need a special classloader like a servlet container that picks up the packaged jars and places them on the classpath” — sounds right?

awesome, yes

so like jetty or tomcat for example

I have no clue if I got the lingo right 😛

when you load your app it dumps it to disk

like when you deploy to tomcat for example

it unzips the war file and dumps the contents to a working directory

and it starts a new classloader with the dumped jars and directories on the classpath

it runs your servlet in that classloader context

does that make sense?

that sounds understandable

@micha: thanks for the explanation

@micha: i commented on https://github.com/boot-clj/boot/pull/239 what do you think?

@alandipert: looks great yes

ok pushing 2.2.0 🚬

📡 🍑

making an uberjar without :as-jars is amazingly slow 😵

hopefully it’s faster on CI

are you making a cli thing?

@alandipert: no. big server thing. will move to starting from boot soon but would like to get it working with plain uberjar first for now

a web app? i’m just curious if boot-ubermain is an option for you to try

certainly is an option

gave up at:

i think you just need to supply the -m option to give it an entrypoint

like boot ubermain -m my.ns/-main

oh. does just the namespace not work?

now that explains why it’s called main-var not main

https://twitter.com/adzerktech/status/628683332193251328

@alandipert: trying ubermain again.

I've updated the boot nix package (that I'm probably the sole user of but whetever 👯): https://github.com/NixOS/nixpkgs/pull/9118

@ragge: actually just chatted with another nix user and discovered that you maintain that package!

the world is crazy small 😄

especially the nix world

@ragge there’s going to be a nix conf in Berlin in November: http://conf.nixos.org/

@martinklepsch: yeah, saw that... i'd love to see nix get a bit more attention

@martinklepsch: clojure people should like it

@martinklepsch: are you using nix/nixos?

I’m on mac but I’m considering trying it out before I do a clean install (not that this would be necessary)

@alandipert: could it be that the ubermain doesn’t terminate when there’s an exception while calling the var I gave as main-var?

@martinklepsch: possible, but i would expect it to terminate - the java code doesn’t catch any exceptions, so i’d expect them to bubble up

i will test myself

trying again, maybe it was just my computer being slow at printing a prompt

when my main function throws an exception, i see java.lang.reflect.InvocationTargetException

(and jvm exit status is 1)

Nothing happening until I ^C

java.util.concurrent.ExecutionException: java.lang.NoSuchMethodError: boot.App.getClojureName()Ljava/lang/String;

This is the error I should get when using an outdated boot.sh with newer library jars right?

@martinklepsch: i'm currently getting the same error but i thought i had updated boot.sh... currently investigating

@ragge I also updated. I can do boot repl outside of directories that have a boot.properties file

@ragge what tasks are you running?

@martinklepsch: yep, same here

@martinklepsch: trying just boot and boot repl so far

i also have a custom task that uses make-pod and that fails at https://github.com/boot-clj/boot/blob/master/boot/pod/src/boot/pod.clj#L458

yeah, repl works for me on dirs with boot.properties and without so that does not seem to be the factor

stacktrace also comes from make-pod here

@alandipert: ping

hey, yeah something is up

i think i might have uploaded the wrong boot.sh

what are your boot.sh md5s please?

e0b3ef41bffbedb918e7057a54e1e2ee

e0b3ef41bffbedb918e7057a54e1e2ee

@alandipert: I built from master like half an hour ago and had that exception before I updated the boot executable so yeah

sounds as if that could be the cause

however, I can run (boot.pod/make-pod) in boot repl

ok weird the one i built is ebe693b4f2283487d8ef6134e2e16485

and the one on github is definitely e0b3ef41bffbedb918e7057a54e1e2ee

so either i chose the wrong one or the upload borked somehow

err, (boot.pod/make-pod {}) fails with java.lang.NoSuchMethodError: boot.App.getClojureName()Ljava/lang/String;

wrong arity

i think i uploaded the wrong boot.sh 😦

d514cd596b38f5f005488b0e240f75eb — that’s what I get when building from master

can you please try with that one and lemme know if works? if does, suspicion confirmed

@martinklepsch: our md5s likely differ because you compiled with java 8, we compile with javac 7 for releases

@alandipert: gotcha

has been said a million times but CircleCI’s ssh access is just great.

@alandipert: i get the same md5 for the boot.sh you just uploaded

to slack that is

e0b3ef41bffbedb918e7057a54e1e2ee

same

ok, i updated the release page with a new boot.sh

should be the correct one - please try

sorry for all this! thanks for the help fixing

let’s just pretend that this never happened and that release binaries are immutable

works for me

drumroll

yay

works!

sweet!

immutable-ish

now:

lol — wanted to paste some champagne gif and found this: http://media.giphy.com/media/v65N3d8y7Dj9e/giphy.gif

LOL

i like how he holds it up at the end anyway

@alandipert: https://github.com/boot-clj/boot/issues/266 — uploaded new exe as well?

commented without reading the thing 😏

@martinklepsch: yeah i’m confident that exe is new also

👍

@martinklepsch: https://twitter.com/adzerktech/status/628700813943271424

haha

perfect
