**FastAPI** is all based on Pydantic.

You will see a lot more of all this in practice in the [Tutorial - User Guide](tutorial/index.md){.internal-link target=_blank}.

以下命令展示了如何使用 zip 下载：

    $ unzip fess-14.17.x.zip
    $ cd fess-14.17.x
    $ ./bin/fess

### Docker

我们在 [ghcr.io](https://github.com/orgs/codelibs/packages) 上提供了 Docker 镜像。我们还在[此存储库](https://github.com/codelibs/docker-fess/tree/master/compose)中提供了 Docker Compose (YAML) 文件。

    // We'd prefer to operate directly on `result` but it doesn't offer insertCodePoint(), only
    // appendCodePoint(). The Punycode algorithm processes code points in increasing code-point
    // order, not in increasing index order.
    val codePoints = mutableListOf<Int>()

    // consume all code points before the last delimiter (if there is one)
    //  and copy them to output, fail on any non-basic code point
