Hi everyone, sorry if that's a dumb question, but how do I reload/reactivate build.boot while in the boot repl?

When changing dependencies, adding tasks, etc

(eval (read-string-all (slurp "build.boot"))) kinda seems to work, but also reports a null pointer exception (asyncronous?); wonder if there's a better way

@mitranim you can do (load-file "build.boot") in the repl

that's clojure.core/load-file

there is also clojure.core/load-string btw

@micha Works, and without exceptions, nice. Thanks!

eval won't do the right thing exactly

why a difference?

I mean load-string literally says "read and evaluate"

Load string handles multiple top level forms

huh now I see the error, was feeding it a list of top-level forms

it evaled them all, then tried to call the result of (set-env! ...) as a function...

load is different from eval, i'm pretty sure

(doseq [form (read-string-all (slurp "build.boot"))] (eval form)) seems to produce a similar result

https://github.com/clojure/clojure/blob/d8aad06ba91827bf7373ac3f3d469817e6331322/src/jvm/clojure/lang/Compiler.java#L7363-L7387

(doesn't return the result of the last form though)

if your file is a namespace eval totally won't do it

like evaling forms to create a new namespace etc

I see

the build.boot case isn't a namespace, so evaling could work

interesting, that looks like it's just reading and evaling

now i am confused

@micha isn't load-file also classpath aware, so it can resolve the namespace stuff

not sure
