This will set up the Grain runtime, standard library, and CLI.

If running tests is your kind of thing, run

yarn compiler:test

Other Commands

yarn stdlib:build

To build the runtime:

yarn runtime:build

To link the CLI:

yarn cli:link

To reset your compiler build:

echo "print('Hello world')" > hello.gr
grain hello.gr

Alternatively, you can invoke the compiler directly:
