Add OpenAPI/Swagger JSON output subcommand

[mschwager]

E.g. https://swagger.io/specification/

It'd be helpful to have a subcommand that can turn Semgrep JSON results into an OpenAPI/Swagger JSON spec. This spec file could then be used in DAST scanners or other tools that ingest this format. This would be a convenient way to analyze code, and turn this analysis into something widely used by other tools.

had this same exact idea to feed into DAST yeah, maybe a good cli prompt interface or some extra flags, to tell the server/host url, base path etc...
