cli-matic

I've been learning Clojure recently and loving it, but one thing I've found myself missing from my Golang days is how easy it is to build and deploy CLI tools in Golang. 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

I use it extensively for automating tasks, and it's pretty good. Sure, it's not as snappy as a Go executable, but: 1. you get all JVM libraries (eg JDBC) 2. it's very compact to write and maintain 3. you can develop stuff using a REPL, and this is very handy for ill-defined problems. 4. if the result is worth it, I can create a Graal native for it (but I hardly ever use this) I ended up as an author of a thing to minimize the boilerplate involved: https://github.com/l3nz/cli-matic

Clojure 1.10 (actually Spec) does not work with GraalVM - but 1.9 works fine: https://github.com/l3nz/cli-matic/issues/64#issuecomment-485...

I use scripting extensively in Clojure, both on the JVM and on Planck (JS). You have the choice of slower startup times but a ton of libraries to do anything you want, versus short start-up times but less libraries, using the same language. I use https://github.com/l3nz/cli-matic as a wrapper and it works on both.

> I hope that some derivative of perl can rise from the ashes, because I'm too stupid to write actual lisp programs, but perl allows me to emulate what I imagine lisp programmers must feel. Well, there is Clojure. You can script it with `clj` and https://github.com/l3nz/cli-matic, and/or one of the ClojureScript interpreters. It has sane library management, so there is no PITA installing anything. You have JVM libraries, so you have all you need. We find it pretty handy.
