自定义您的设置：创建 settings_user.yml¶
请先克隆源代码以重新创建此项目。您可以在 GitHub 的 examples2 存储库中找到它们。
$ git clone https://github.com/conan-io/examples2.git
$ cd examples2/examples/config_files/settings_user
在此示例中，我们将了解如何在不覆盖原始 settings.yml 文件的情况下自定义您的设置。
注意
为了更好地理解此示例，强烈建议您先阅读有关 settings.yml 的参考资料。
找到 settings_user.yml¶
首先，让我们看一下建议的 source/settings_user.yml
settings_user.yml¶
os:
webOS:
sdk_version: [null, "7.0.0", "6.0.1", "6.0.0"]
arch: ["cortexa15t2hf"]
compiler:
gcc:
version: ["13.0-rc"]
如您所见，我们不必重写所有设置，因为它们将与 settings.yml 中已定义的设置合并。
那么，我们通过 settings_user.yml 文件添加了什么呢？
新的操作系统：
webOS及其子设置：sdk_version。可用的新
arch：cortexa15t2hf。新的 gcc 版本：
13.0-rc。
现在，是时候将文件 source/settings_user.yml 复制到您的 [CONAN_HOME]/ 文件夹中了。
$ conan config install sources/settings_user.yml
Copying file settings_user.yml to /Users/myuser/.conan2/.
使用您的新设置¶
复制 settings_user.yml 后，您应该能够将其用于您的配方。将这个简单的配方添加到您的本地文件夹中
conanfile.py¶
from conan import ConanFile
class PkgConan(ConanFile):
name = "pkg"
version = "1.0"
settings = "os", "compiler", "build_type", "arch"
然后，创建几个 Conan 包（不是二进制文件，因为它肯定没有任何源文件）以查看它是否正常工作
使用新的操作系统及其子设置¶

正如您所观察到的，每个命令都创建了一个不同的包。这完全正确，因为我们为每个命令使用了不同的设置。 如果您想查看创建的所有包，可以使用 conan list 命令
