## Conditional OpenAPI from settings and env vars

You can easily use the same Pydantic settings to configure your generated OpenAPI and the docs UIs.

For example:

{* ../../docs_src/conditional_openapi/tutorial001.py hl[6,11] *}

    # keywords for environment properties, same as directory name
    ; environmentList = list:{}

    # environment dispatch by lasta.env of system property?
    ; isUseLastaEnv = false

    # settings for web applications
    ; appMap = map:{
        ; fess = map:{
            ; path = ..
            ; freeGenList = list:{ env ; config ; label ; message ; mail ; template ; jsp ; doc }

        - 'https://server4-pool2:9000/mnt/disk{1...4}/'

options:
  ftp: # settings for MinIO to act as an ftp server
        address: ':8021'

        address: ':8022'

    // GET /api/admin/labeltype/settings
    // POST /api/admin/labeltype/settings
    @Execute
    public JsonResponse<ApiResult> settings(final SearchBody body) {
        validateApi(body, messages -> {});
