Oh, you know me: I avoid AOT and gen-class at all costs _if I don’t have to use them_ 😊

On Jun 21, 2019, at 2:35 PM, Sean Corfield <s...@corfield.org<mailto:s...@corfield.org>> wrote: The approach I’ve taken around :gen-class has been to ensure that the namespace offering the Java class via :gen-class has no static dependencies at all – instead it requires/resolves any other namespaces/symbols it needs at run time. That way AOT creates the .class you need but doesn’t spread to anything else. This is even easier in Clojure 1.10 with the addition of requiring-resolve (which is also thread safe, unlike regular require right now). But yeah, as Alex indicated, you need to be careful if you have an AOT’d entry point and downstream code is not AOT’d. Just one more “here be dragons” aspect of AOT, IMO.

When you go with Option #2, you do not have to AOT everything, but AOT is transitive. So as you AOT the gen class, all code it requires and all code they in turn require will also be AOT. You can post-process the AOT when jaring, and only include the gen-class .class files in the Jar and not the dependencies, but that's more work. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
