# 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。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
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=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
