Developing Babashka

To work on Babashka itself make sure Git submodules are checked out.

$ git clone https://github.com/borkdude/babashka --recursive

To update later on:

$ git submodule update --recursive

You need Leiningen, and for building binaries you need GraalVM.

REPL

lein repl will get you a standard REPL/nREPL connection. To work on tests use lein with-profiles +test repl.

Adding classes

Add necessary classes to babashka/impl/classes.clj. For every addition, write a unit test, so it's clear why it is added and removing it will break the tests. Try to reduce the size of the binary by only adding the necessary parts of a class in :instance-check, :constructors, :methods, :fields or :custom.

The reflection.json file that is needed for GraalVM compilation is generated with:

lein with-profiles +reflection run

Test

Test on the JVM (for development):

script/test

Test the native version:

BABASHKA_TEST_ENV=native script/test

Build

To build this project, set $GRAALVM_HOME to the GraalVM distribution directory.

Then run:

script/compile

Binary size

Keep notes here about how adding libraries and classes to Babashka affects the binary size.
