has anyone boot-ized the luminus project yet? looking for a good full stack template similar to Tenzing

To save me going and figuring out the answer: does TravisCI support Boot?

(I mean "out of the box" like it does for Leiningen)

Not that I know of

I guess you could install boot.sh as the install step of TravisCI?

Anyone here update a cljsjs package?

What is an .inc.js file for?

https://github.com/clojure/clojurescript/wiki/Dependencies#cljsjs

@currentoor: I think inc and min.inc.js are the library code itself

ext.js are google clojure compiler externs

i see

thanks

np, hope that helps

The extensions are a convention used in cljsjs packages. They are used by deps-cljs task when packaging cljsjs libs.

Hello. I'm relatively new to boot and am just trying to create a (pure clojure - no cljs) project that uses 'watch' and recompiles when I change a file in my source-paths.

I have these tasks: (deftask bundle [] (comp (speak) (aot) (pom) (uber) (jar))) (deftask dev [] (comp (watch) (repl) (bundle)))

When I change a file, I get Could not locate james/imbibe__init.class or james/imbibe.clj on classpath. (after i edit imbibe.clj)

Killing boot and executing 'boot dev' once again takes forever to restart (building the uber?). What is the best way to do this?

Thanks...

@inhortte: i would avoid aot as much as possible

clojure isn't really designed for it

so you will see confusing errors

So I should just get rid of (aot)? (I'm still learning boot and possibly don't even know what aot actually does...)

aot compiles clojure namespaces to .class files

the only time you need that is when you make an uberjar and need to have a main class

I have removed (aot) from the 'bundle' task and now I get the following error: Error: Could not find or load main class james.core when running java -cp target/project.jar james.core http://localhost:3554/new-index.html

right so you will need aot there, but to avoid problems you can make a minimal shim

like this

How do I execute the program?

suppose your program entry point is james.core/-main

what you can do is craeate a new namespace, james.main

with the following contents

(ns james.main
  (:gen-class))
  
(defn -main [& args]
  (require 'james.core)
  (apply (resolve 'james.core/-main) args))

then you do this in your build.boot:

(task-options!
  aot {:namespace #{'james.main}}
  jar {:main 'james.main})

ok...

that will restrict the aot (ahead-of-time) compilation to that one namespace

(thank you very much, by the way)

I'm about to try it...

then you can do boot aot uber jar target

and you will have an uberjar in target/project.jar

then you can do java -jar target/project.jar

Need I remove (:gen-class) from james.core?

yes

ok.

you don't need the pom task either

since you're building an appliction and not a library that will be deployed to maven

all right.

if you want to end up with just the jar file in the target dir you can do this, too

boot aot uber jar sift --include '\.jar$' target

> java -cp target/project.jar james.main http://localhost:3554/new-index.html Exception in thread "main" java.io.FileNotFoundException: Could not locate james/core__init.class or james/core.clj on classpath.

do java -jar target/project.jar

not java -cp

hm actually that isn't the problem

the problem is that your clj source files are in :source-paths probably

yeah.. i just tried java -jar.

they should be in :resource-paths

oh?

so they will be included in the jar

what is the purpose of :source-paths?

that's the difference between :source-paths and :resource-paths

both are on the build classpath, but :sourec-paths isn't included in packaging, like the target dir or jar files etc

more info about that here: https://github.com/boot-clj/boot/wiki/Filesets#roles-of-files

Ok... I'll consult the page for that.

And with sift...

in the boot file, (comp (speak) (aot) (uber) (jar) (sift :include #"\.jar$") (target))

... um... no.

you can do (doc sift) in the repl

to see the kwargs it accepts and what type the options expect

for example you will see for the :include option

:include       #{regex}     The set of regexes that paths must match.

that means it's expecting a set of regexes

so you want (sift :include #{#"\.jar$"})

perfect. again... thanks.

also you can see api docs online here, if that is easier for you

https://github.com/boot-clj/boot/blob/master/doc/boot.task.built-in.md

all the public api namespaces are here https://github.com/boot-clj/boot/tree/master/doc

I put it in task-options! in the task definition.

yeah task-options! simply replaces the var with a curried version

the watch is working, as well.

changing aot compiled namespaces without restarting the jvm is problematic

so using the minimal shim means you don't have to change that

loading clj namespaces is fine because the classes it generates are basically anonymous

the created jar is fine for production, as well, or do you suggest other means?

when you recompile a clojure namespace you'er not overwriting any existing classes

yeah that's what i do in production as well

Off topic - Just wondering with a nickname like 'micha', are you in the slavic world somewhere?

Anyhow. It's working fantastically. Thanks for your help.

that's my name

i'm in the usa but i'm named after my grandfather who was from belarus

@inhortte: if you get a moment and want to update the wiki with a note about aot and watch that would be most appreciated, but no pressure

the boot wiki?

yep

it's sort of a collection of tips and tricks in addition to the normal documentation

Anybody know how boot-http is supposed to work with webjars?

Where in the wiki would it be appropriate to put?

i keep forgetting to monitor stack overflow, which would probably be the most googlable way to make these little tricks available

@inhortte: wherever you think it belongs will be fine, i'm sure

Ok, @micha, I shall look over it later this evening.

thanks @inhortte

no problem.

@micha: Let me know what you think and if I should add / subtract / obliterate anything: https://github.com/boot-clj/boot/wiki/Watch-and-Code-Reloading

@inhortte: very nice!

perhaps rename the article to be something related to working around limitations of the watch task and aot combination?

like the shim is to allow you to avoid aot compilation of namespaces you'll be changing

i imagine a lot of people run into this tricky situation

@inhortte: awesome!

Gracias @richiardiandrea

@micha I changed a few things... https://github.com/boot-clj/boot/wiki/Circumnavigating-Watch-and-AOT-Compilation-Limitations

Not that anyone will care but I switched FW/1 (a lightweight MVC framework) over to Boot, including making its template a Boot-specific one. It was a Leiningen template before.

Partly because we’re starting to use FW/1 at work. We’ve been using the CFML version of FW/1 for years. We’re just, finally, starting to write end-to-end Clojure web apps and therefore using the Clojure version of FW/1!

But that isn't clojurey! Framework?!

@seancorfield: I'm interested to see how that framework plays out.

I think #C0702A7SB is interesting. But I'm a juxter, so I'm biased 😛

@dominicm: Yeah, one of the things I want to do with FW/1 is make it a bit more idiomatic at some point. Right now it’s Ring + Selmer + convention-based routing so I want to make that part a separate library and then turn the rest into something more like Ring Middleware.
