CONFIG OPTIONS​

These options may be applied as additional-properties (cli) or configOptions (plugins). Refer to configuration docs for more details.

OptionDescriptionValuesDefault
allowUnicodeIdentifiersboolean, toggles whether unicode identifiers are allowed in names or not, default is falsefalse
apiNamespacesub-namespace the api resource classes are nested under, to separate them from same-named models (e.g. "Api" -> Foo::Api::Pet). Set to an empty string to nest the api classes directly under moduleName (e.g. when moduleName already ends with "Api").Api
disallowAdditionalPropertiesIfNotPresentIf false, the 'additionalProperties' implementation (set to true by default) is compliant with the OAS and JSON schema specifications. If true (default), keep the old (incorrect) behaviour that 'additionalProperties' is set to false by default.
false
The 'additionalProperties' implementation is compliant with the OAS and JSON schema specifications.
true
Keep the old (incorrect) behaviour that 'additionalProperties' is set to false by default.
true
ensureUniqueParamsWhether to ensure parameter names are unique in an operation (rename parameters that are not).true
enumUnknownDefaultCaseIf the server adds new enum cases, that are unknown by an old spec/client, the client will fail to parse the network response. With this option enabled, each enum will have a new case, 'unknown_default_open_api', so that when the server sends an enum case that is not known by the client/spec, they can safely fallback to this case.
false
No changes to the enums are made, this is the default option.
true
With this option enabled, each enum will have a new case, 'unknown_default_open_api', so that when the enum case sent by the server is not known by the client/spec, can safely be decoded to this case.
false
hideGenerationTimestampHides the generation timestamp when files are generated.true
legacyDiscriminatorBehaviorSet to false for generators with better support for discriminators. (Python, Java, Go, PowerShell, C# have this enabled by default).
true
The mapping in the discriminator includes descendent schemas that allOf inherit from self and the discriminator mapping schemas in the OAS document.
false
The mapping in the discriminator includes any descendent schemas that allOf inherit from self, any oneOf schemas, any anyOf schemas, any x-discriminator-values, and the discriminator mapping schemas in the OAS document AND Codegen validates that oneOf and anyOf schemas contain the required discriminator and throws an error if the discriminator is missing.
true
moduleNamemodule name (e.g. TwitterClientOpenAPIClient
paramsEncoderparams_encoder setting (e.g. Crest::NestedParamsEncoder, Crest::EnumeratedFlatParamsEncoder, Crest::ZeroEnumeratedFlatParamsEncoderCrest::NestedParamsEncoder
prependFormOrBodyParametersAdd form or body parameters to the beginning of the parameter list.false
