Anaconda XZ包装含量的测定

Question

我目前正在试图找出一个anaconda包名为XZ的内容。

据我理解，这个包为XZ Utils (数据压缩工具)提供了绑定。

我试图找出包中存在的XZ组件，它是只有liblzma库，还是有命令行工具和shell脚本。有人能帮我吗？

非常感谢您抽出时间:)

尝试的方法

我试着从环境的conda-meta文件夹中查看XZ包json文件。我相信conda-meta文件夹保存每个已安装包的元数据。

json文件的内容如下。

}

从“文件”部分，我相信它告诉了包提供了哪些文件。它确实声明它有liblzma库。它还显示了"xz.exe"，我认为它可能是命令行工具，但我不能保证。

动机

就上下文而言，我实际上试图避免使用gpl许可的软件。从文档中，它声明了对xz utils的不同部分应用了不同的许可证。。在进行了一些研究之后，python实际上已经有了一个与liblzma结合的buildin，所以我想知道这个包提供了什么。

Answer 1

我找到了一个与我的问题相对应的XZ conda锻造包装的回购问题。

我在关于开放源码堆栈交换的问题上发布了更多关于这个的文章。

简而言之，包中不存在“grep、diff和view压缩文件的脚本”组件。

然而，对于命令行组件，问题仍然存在。

Answer 2

是的，files:部分列出了将安装到环境中的文件。bin/下的程序是可执行程序，lib/是共享库，include/是针对它编译的头文件。
