The Docker image to automatically create a representation for Crystal solutions submitted to Exercism.

To create a representation for an arbitrary exercise, do the following:

1. Open a terminal in the project's root
2. Run ./bin/run.sh <exercise-slug> <solution-dir> <output-dir>

Once the representer has finished, its results will be written to <output-dir>/representation.txt and <output-dir>/mapping.json.

This script is provided for testing purposes, as it mimics how representers run in Exercism's production environment.

To create a representation for an using the Docker image, do the following:

1. Open a terminal in the project's root
2. Run ./bin/run-in-docker.sh <exercise-slug> <solution-dir> <output-dir>

Once the representer has finished, its results will be written to <output-dir>/representation.txt and <output-dir>/mapping.json.

To run the tests to verify the behavior of the representer, do the following:

1. Open a terminal in the project's root
2. Run ./bin/run-tests.sh

These are golden tests that compare the representation.txt and mapping.json generated by running the current state of the code against the "known good" tests/<test-name>/representation.txt and tests/<test-name>/mapping.json. All files created during the test run itself are discarded.

When you've made modifications to the code that will result in a new "golden" state, you'll need to generate and commit a new tests/<test-name>/representation.txt and tests/<test-name>/mapping.json file.
