description = "A Clojure babushka for the grey areas of Bash";
longDescription = ''
The main idea behind babashka is to leverage Clojure in places where you
would be using bash otherwise.
As one user described it:
I’m quite at home in Bash most of the time, but there’s a substantial
grey area of things that are too complicated to be simple in bash, but
too simple to be worth writing a clj/s script for. Babashka really
seems to hit the sweet spot for those cases.
Goals:
- Low latency Clojure scripting alternative to JVM Clojure.
- Easy installation: grab the self-contained binary and run. No JVM needed.
- Familiarity and portability:
- Scripts should be compatible with JVM Clojure as much as possible
- Scripts should be platform-independent as much as possible. Babashka
offers support for linux, macOS and Windows.
- Allow interop with commonly used classes like java.io.File and System
- Multi-threading support (pmap, future, core.async)
- Batteries included (tools.cli, cheshire, ...)
- Library support via popular tools like the clojure CLI
