JBang, a Java file to rule them all? 💍
summary
Demo shows JBang (installed via SDKMAN/brew/curl, version JBang 0.137) turning a ten‑line HelloWorld into a runnable script by building an executable jar on demand and supporting shebang install so the file runs like a normal command. Adds Maven-style deps (demo uses LangChain4j and Logback), file packing for logback.xml, installs aliases, and pulls scripts/catalogs from GitHub. Notes JDK 11 single‑file limits (improved by JDK 25), installs scripts globally and the demos all run; GraalVM native build is possible but not favored for readable scripts.
