alt Hacker NewsI spent a long time caring about JVM startup time and CLI suitability (and wrote nailgun [0] over 20 years ago and jsap [1] shortly after specifically because of it), so it's pretty wild to see how far things have come. Modern JVM startup speed and GraalVM native-image have eliminated most of the old excuses. jlink+jpackage help a lot with distribution, and JBang takes it to another level. I've used JBang before but still learned some new tricks from this post. Honestly, it feels like what JNLP/WebStart should have evolved into.
I'm not convinced that requiring users to already have JBang installed is the best adoption strategy. But a native package that pulls in JBang if needed and drops a shim launcher/desktop shortcut seems like a natural approach and maybe a fun project.
On the TUI side, java could really use something as approachable and pretty as go's Charmbracelet [2]. Once developers regularly see compelling java TUIs in the wild, it'll change their perception.
The tooling is here, or at least really close. At this point, it's mostly outdated opinions holding java back in the terminal.
