@kenny Not possible, default options are handled inside Cljs compiler, there is no API to get them

Reposting my earlier question: What do boot users use as a substitute for the lein-ring plugin?

@kumarshantanu https://github.com/boot-clj/boot-war-example is one example

@kumarshantanu boot-http, boot-serve come to mind, there are more options…

Thanks, @alandipert @martinklepsch

does anybody have an example of how to use --filter with boot-test?

In deftask dev (in boot-war-example) I am trying to (require '[foo.bar :as bar]) (bar/baz) but it errors out saying No such namespace: bar

What’s a better way to require a namespace and call a fn in it?

Fixed it by putting the require outside of the task

You could use resolve instead

When this PR is merged (https://github.com/boot-clj/boot/pull/597), the new call task could help as well

(clandestine advocacy for my PR alert)

@pesterhazy wow, thanks! I was looking for a boot alternative to lein run too

which this PR seems to be addressing

correct 🙂

I’m trying to debug a stack trace in boot dev run

Can anybody share a pointer on how to debug this?

I’m using boot 2.7.1

@kumarshantanu try boot -b to print the generated script to see line numbers

@pesterhazy Thanks, line number 19 is as follows: (clojure.core/let [boot?__1744__auto__ true] (clojure.core/if-not boot?__1744__auto__ (clojure.core/when-let [main__1745__auto__ (clojure.core/resolve (quote boot.user/-main))] (main__1745__auto__)) (boot.core/boot "boot.task.built-in/help")))

looks like boot.user/-main does not exist?

@kumarshantanu ^^

@pesterhazy I have no reference to any boot.user/-main in my build.boot file

it's hard to help without seeing the boot file

@pesterhazy I’ve pasted my build.boot file here: https://pastebin.com/09Hc2i9v

@pesterhazy Sorry to bother you, I found the issue was handler-init returning nil, which was one of the args to comp.

no problem, it's a bit tricky to build.boot

I have a question about the set-env! function. Are all the keys present on ? In particular I have seen :init-ns mentioned in build.boot files in other projects and am wondering what it does.

The boot run task is not a built-in for boot. shows that the namespace is not optional. If that argument is not present a java.lang.NullPointerException results. When this boot task failed there is little information to guide the search (in this case I stumbled upon the root cause).
