how to use -Dapis flag - Githubissues

adamgreenhall commented 2 years ago

Description

I'm trying to figure out how to use the -Dapis flag to filter the api paths being generated, but I can't seem to figure it out. And it's not documented with the other examples in https://github.com/swagger-api/swagger-codegen#selective-generation

Swagger-codegen version

3.0.30

Swagger declaration file content or url

https://petstore.swagger.io/v2/swagger.json

Command line used for generation

I've tried a few different things - none of them seem to work:

java -Dapis="/pet/{petId}/uploadImage" -jar swagger-codegen-cli.jar generate -l go -i https://petstore.swagger.io/v2/swagger.json -o test
java -Dapis="/pet" -jar swagger-codegen-cli.jar generate -l go -i https://petstore.swagger.io/v2/swagger.json -o test

Using the path tag (but capitalized for some reason, lowercase doesn't work) does generate all code for api path methods with that tag: java -Dapis="Pet" -jar swagger-codegen-cli.jar generate -l go -i https://petstore.swagger.io/v2/swagger.json -o test but I'd like to filter to a subset of these methods, if possible.

Suggest a fix/enhancement

Ideally, we could document how to use the -Dapis flag to filter apis.

flag handling code appears to be here:

I got it to work with the tags from the paths attribute. Please try.
