1. How do I install this? Is it a clojar or a separate binary?
2. How do I use it? You reference bbb once in the README but then use bb in examples farther down.
Both of these may be ID10T errors where I missed a link to additional documentation…
I’ll update the docs to make that a little clearer :)
With GraalVM it's finally possible to compile Clojure apps into static binaries that give your users a deploy and startup experience similar to Go's, but I found GraalVM very difficult to configure and use, and was often frustrated because not all JVM code is compatible with GraalVM. Worse still, because native-images take a while to build you often don't find out that your working JVM Clojure code won't work as a native-image until it's too late.
BabashkaBins/bbb is my attempt to fix this: it lets you easily run the same codebase under babashka or JVM Clojure, and will automate compiling your project to a static binary for you using GraalVM's native-image. It also takes care of collecting some tweaks that make it easy to use the cli-magic [2] library under babashka, which means you can easily make complex CLI tools with nested subcommands a la git or docker, with all the bells and whistles.
Since babashka is itself compiled under GraalVM, this arrangement provides a other few nice benefits: 1) babashka starts quickly, so you can test your CLI from an actual command line without waiting for the JVM to spin up each time. 2) babashka's codebase contains a treasure trove of GraalVM related tweaks and fixes that using bbb lets you take advantage of in your own CLIs for free, and 3) it functions as a quick sanity check since babashka itself is compiled under GraalVM. If you find yourself doing something that's not GraalVM compatible at least you'll know early!
