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
