# 4.6.处理用户输入

如果 Port 在构建、配置或安装时需要用户输入，请在 **Makefile** 中设置 `IS_INTERACTIVE`。这将允许“过夜构建”跳过这些步骤。如果用户在环境中设置了变量 `BATCH`（如果用户同时设置了变量 `INTERACTIVE`，那么*只有*那些需要交互的 Ports 会被构建）。这将节省那些持续构建 Ports 的机器上的大量时间（见下文）。

如果问题有合理的默认答案，建议在 `PACKAGE_BUILDING` 被设置时使用它来关闭交互式脚本。这将允许我们为 CDROM 和 FTP 构建软件包。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/porters-handbook/di-4-zhang-fu-za-de-port/4.6.-chu-li-yong-hu-shu-ru.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
