Reagent lets ClojureScript developers write React UI in Hiccup syntax, using atoms for reactive state and hot reloading via shadow‑cljs. This blog explains its benefits, shows a counter example, discusses performance trade‑offs, and gives a practical checklist to get started.
Context SWI-Prolog 8.5 introduced use_module/2 with the reload(true) option, which replaces predicate definitions atomically within a single thread. This capability is documented as a mechanism for updating logic without restarting the runtime. Constraint The documentation and ISO/IEC 13211 do not specify behavior when multiple threads concurrently execute p
Emacs server mode lets a single daemon process host multiple emacsclient sessions that share one Lisp image, so reloading an application's source with load-file or eval-buffer updates function definitions for every connected client at once. The refresh, however, is not guaranteed to be complete: advice attached to a function, closures that captured an earlie
State Persistence in Hot-Reloading Reflex allows developers to maintain component state across code changes using the preserve_state flag. While this ensures synchronous state values remain intact when the binary recompiles and the UI re-instantiates, the behavior of asynchronous operations during this transition is less clear. When a reload is triggered whi
Dynamic Logic Updates in Clojure Clojure allows for the modification of application logic without restarting the JVM by utilizing clojure.core/alter-var-root or the reload function to refresh namespace definitions. This capability is often used to decouple logic updates from the application state, typically managed via atoms or agents. Constraints on State a
