Instead, all casing-related work is done when the Regex is OAS 3 This page is about OpenAPI 3. The OpenAPI Specification standard allows specifications to stipulate a schema to describe the data type of a parameter or field. To discuss: Should the code generation be responsible When generating code, there is no difference to the underlying data types about pattern matching, so you won't see any changes. if we have an annotation with an inner property like @Capitalized(required = “true”), then a particular pattern on the second line of the beanValidationCore. com" domain name are case-insensitive, so uppercase letters are permitted.

And here is where our regex patterns are placed in the generated python code. You now provide a discriminator object which contains the name of the discriminator property, as well as a mapping of values of that property to schema names.

If you want pure regex then you can just take out the length check. I assume that you use OpenAPI 3. Recognizers can be loaded from a YAML file, which allows users to add recognition logic without writing code. Though the pattern is picked up by swagger for String type variables while swagger does not pick a pattern for a list of strings. To prevent the empty string you could provide a pattern regex. However, the same node could be used in the last where object Has there been any update on this, we are attempting to parse 3rd party openapi schemas where we can't change the contents of the file and have run into a number of issues where we fail to load the file due to it failing regex validation even though we don't use the compiled pattern ourselves, just require the raw string The following 4 regex patterns can help you to write almost any password validation. [^abc]: Matches any character not listed. Contribute to OAI/OpenAPI-Specification development by creating an account on GitHub.
