swagger-codegen:tldr:f110b

The swagger-codegen command is used to generate a client or server code from a Swagger/OpenAPI specification file.

The langs parameter in the command is used to retrieve the list of available language templates that can be used with swagger-codegen. It lists all the supported programming languages for code generation.

When you execute the swagger-codegen langs command, it will display a list of programming languages that are supported by the Swagger Codegen tool. This helps you identify which languages you can use to generate code based on your requirements.

For example, executing the swagger-codegen langs command might return a list like:

Available languages/Generators:
[ ada
, ada-server
, ruby
, swift
, swift3
, tizencli
, tizen
, ..
]

This output indicates that you can use ada, ruby, swift, tizencli, etc., as options for the -l parameter when generating code using swagger-codegen for the specified language.
