Crystal API Client Generator

Hi all,

We’ve just added a Crystal client generator to the openapi-generator project:

Please give it a try by following 3 simple steps below:

  1. Download the Java JAR: oss.sonatype.org/content/repositories/snapshots/org/openapitools/openapi-generator-cli/5.0.1-SNAPSHOT/openapi-generator-cli-5.0.1-20210107.102010-25.jar

  2. Rename the JAR as “openapi-generator-cli.jar”

  3. Execute the following command to run the generator for the Petstore API:

Mac/Linux:

$ java -jar openapi-generator-cli.jar generate -g crystal -i https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml -o /var/tmp/crystal-client/

I’m new to crystal so the output may not look best. Welcome feedback, PRs to further improve it.

I just tried it out, way too ambitiously — I got a little excited and ran it against the Stripe OAS3 definition. :-D Just opened up a PR to fix some of the issues I saw.

When I get a bit more time I’ll look through it some more (I’m stumbling on rebuilding the Maven package at the moment), but I hope that PR helps move it forward.

I’m a little behind the times on generating API clients, but I’ve at least come around to the idea and I’m really excited about this! Thank you so much for working on it!
