Thanks, Alex! That helps a lot. Is my understanding of how uberjars with aot complication work otherwise correct? I.e. apart from the dynamically loaded
One thing I particularly care about is compile-time precomputation. My app uses source JSON data (that I don't control) that's pretty big, but the stuff it produces from that data is pretty small. In ClojureScript, I did this by just using macros, since ClojureScript conveniently guarantees those will be evaluated on the JVM and compile time. So, for example, when I was using ClojureScript to write a GreaseMonkey script/WebExtension (where there are good reasons to keep everything in a single file) and i wanted to include e.g. some literal CSS in the source, I'd just use a macro. Does a similar trick work with Clojure and AOT compilation + uberjar, or should I use a resource as an intermediate? I'm fine with it loading e.g. instant18.clj (although it'd certainly be neater if I didn't have to :))) thanks in advance, lvh On Mon, Apr 3, 2017 at 9:24 AM, Alex Miller <a...@puredanger.com> wrote: > core_instant18.clj is conditionally loaded if you are using >= Java 1.8 to > extend the Inst protocol to java.time.Instant (which didn't exist in prior > JDKs).
