# Generate OpenAPI definitions
- To generate definition for a specific type or package add "+k8s:openapi-gen=true" tag to the type/package comment lines.
- To exclude a type or a member from a tagged package/type, add "+k8s:openapi-gen=false" tag to the comment lines.
# OpenAPI Extensions
OpenAPI spec can have extensions on types. To define one or more extensions on a type or its member
add `+k8s:openapi-gen=x-kubernetes-$NAME:$VALUE` to the comment lines before type/member. A type/member can
have multiple extensions. The rest of the line in the comment will be used as $VALUE so there is no need to
escape or quote the value string. Extensions can be used to pass more information to client generators or
documentation generators. For example a type might have a friendly name to be displayed in documentation or
being used in a client's fluent interface.
# Custom OpenAPI type definitions
Custom types which otherwise don't map directly to OpenAPI can override their
OpenAPI definition by implementing a function named "OpenAPIDefinition" with
the following signature:
```go
import openapi "k8s.io/kube-openapi/pkg/common"
// ...
type Time struct {
time.Time
}
func (_ Time) OpenAPIDefinition() openapi.OpenAPIDefinition {
return openapi.OpenAPIDefinition{
Schema: spec.Schema{
SchemaProps: spec.SchemaProps{
Type: []string{"string"},
Format: "date-time",
},
},
}
}
```
Alternatively, the type can avoid the "openapi" import by defining the following
methods. The following example produces the same OpenAPI definition as the
example above:
```go
func (_ Time) OpenAPISchemaType() []string { return []string{"string"} }
func (_ Time) OpenAPISchemaFormat() string { return "date-time" }
```

NamesMatch implements APIRule interface.
Go field names must be CamelCase. JSON field names must be camelCase. Other than capitalization of the
initial letter, the two should almost always match. No underscores nor dashes in either.
This rule verifies the convention "Other than capitalization of the initial letter, the two should almost always match."
Examples (also in unit test):
Go name | JSON name | match
podSpec false
PodSpec podSpec true
PodSpec PodSpec false
podSpec podSpec false
PodSpec spec false
Spec podSpec false
JSONSpec jsonSpec true
JSONSpec jsonspec false
HTTPJSONSpec httpJSONSpec true
NOTE: this validator cannot tell two sequential all-capital words from one word, therefore the case below
is also considered matched.
HTTPJSONSpec httpjsonSpec true
NOTE: JSON names in jsonNameBlacklist should skip evaluation

podSpec true
