a modular library to create portable shell scripts that run everywhere.

coral is meant to solve the script portability problem the hard way: by writing reusable code and testing it.

There is no compilation or build step. Once you download it, you're good to go:

./entrypoint.sh help

Run all tests locally against the default shell:

./entrypoint.sh tap

Run a single test. For example, the pseudoarray implementation:

sh entrypoint.sh tap 'test/_idiom/005-Arr.sh'

Run all tests inside an ephemeral docker container against all shells:

make docker-matrix
