conan.tools.files 补丁

conan.tools.files.patch()

patch(conanfile, base_path=None, patch_file=None, patch_string=None, strip=0, fuzz=False, **kwargs)

在 conanfile.source_folder 目录中应用来自文件 (patch_file) 或字符串 (patch_string) 的 diff。包含源代码的文件夹可以通过 layout(self) 方法中的 self.folders 属性进行自定义。

参数：

• conanfile – 当前配方，始终传递 'self'

• base_path – 除非提供绝对路径，否则路径相对于 conanfile.export_sources_folder。

• patch_file – 应该应用的补丁文件。除非提供绝对路径，否则路径相对于 conanfile.source_folder。

• patch_string – 应该应用的补丁字符串。

• strip – 要从路径中剥离的文件夹数量。

• fuzz – 是否应该接受模糊补丁。

• kwargs – 可以添加的额外参数，并将有助于输出信息

用法

from conan.tools.files import patch

def build(self):
    for it in self.conan_data.get("patches", {}).get(self.version, []):
        patch(self, **it)

conan.tools.files.apply_conandata_patches()

apply_conandata_patches(conanfile)

应用存储在 conanfile.conan_data 中的补丁（从 conandata.yml 文件读取）。它将应用 patches 条目下所有与给定 conanfile.version 匹配的补丁。如果 conandata.yml 中未定义版本，它将直接应用 patches 关键字下的所有补丁。

键条目将作为 kwargs 传递给 patch 函数。

用法

from conan.tools.files import apply_conandata_patches

def build(self):
    apply_conandata_patches(self)

conandata.yml 示例

  base_path: "subfolder"
  patch_type: backport
  patch_source: https://github.com/google/flatbuffers/pull/5650

对于每个补丁，必须提供 patch_file、patch_string 或 patch_user 字段。前两个由 apply_conandata_patches() 自动应用，而 patch_user 被忽略，必须由用户在 conanfile.py 配方中直接处理。

conan.tools.files.export_conandata_patches()

export_conandata_patches(conanfile)

导出存储在 'conanfile.conan_data' 中的补丁（从 'conandata.yml' 文件读取）。它将导出 'patches' 条目下所有与给定 'conanfile.version' 匹配的补丁。如果 'conandata.yml' 中未定义版本，它将导出 'patches' 关键字下所有补丁。

conandata.yml 示例，未定义版本

from conan.tools.files import export_conandata_patches
def export_sources(self):
    export_conandata_patches(self)
