How can I trigger compilation by changing a file that is not a sourcefile? (it’s a css file I include for lambdaislands ornament, which is included in the :flush stage triggered by a hook in shadow-cljs.edn)

not supported as I strongly recommend not doing anything like this in build hooks

oh

how is that css file relevant to the build?

That css contains color-variables that are included in the file that is built with ornament

ah I guess something like this https://github.com/lambdaisland/ornament#shadow-cljs-build-hook-example?

well yeah, thats a prime example of why I strongly discourage using build hooks for this

you constrain yourself to only being able to generate CSS by running a shadow-cljs build

thats kind of the point

ornament picks up styles I’ve defined in cljs and builds the css

It’s fantastic to work with

hmm ok. I guess what you can do is what this macro does https://clojureverse.org/t/using-none-code-resources-in-cljs-builds/3745

https://github.com/thheller/shadow-cljs/blob/master/src/main/shadow/resource.clj#L49

in a build hook this would be (assoc-in build-state [:compiler-env :cljs.analyzer/namespaces your.ns :shadow.resource/resource-refs "some/path.css"] last-mod)

but it needs to be on the classpath for this to work

so I guess "resources/public/styles.css" becomes "public/styles.css"

ok, I’ll do some research, thanks for the pointers

(need to do this before compilation though, flush is too later)

or I guess in the :compiler-finish stage would do it

hmm yeah this is not the best idea

I think the best option is to handle it outside

I think I solved it (for my use-case) by adding the file to the classpath and using a simple (inline …) in one of the sources

just touch a-source-file.cljs to trigger a recompilation after editing the css

sure that works too

The thing is, this is just for my convenience, saving the css triggers the recompilation and I dont have to go back and forth saving a cljs file to rebuild the css. Now it works just as I wanted, super!

hmm yeah I guess this needs to stay a build hook since it looks at a runtime atom
