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) 的差异。包含源文件的文件夹可以使用 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 – 该路径是 conanfile.export_sources_folder 的相对路径,除非提供了绝对路径。
patch_file – 应该应用的补丁文件。该路径是相对于 conanfile.source_folder 的,除非提供了绝对路径。
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,这些参数将有助于输出信息
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
条目下与给定conanfile.version
匹配的所有补丁。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
的示例
patches:
- patch_file: "patches/0001-buildflatbuffers-cmake.patch"
- patch_file: "patches/0002-implicit-copy-constructor.patch"
base_path: "subfolder"
patch_type: backport
patch_source: https://github.com/google/flatbuffers/pull/5650
patch_description: Needed to build with modern clang compilers.
不同版本使用不同的补丁
patches:
"1.11.0":
- patch_file: "patches/0001-buildflatbuffers-cmake.patch"
- patch_file: "patches/0002-implicit-copy-constructor.patch"
base_path: "subfolder"
patch_type: backport

"1.12.0":
- patch_file: "patches/0001-buildflatbuffers-cmake.patch"
- patch_string: |

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
则会被忽略,必须由用户直接在 conanfile.py
配方中处理。
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' 条目下与给定 'conanfile.version' 匹配的所有补丁。如果 'conandata.yml' 中未定义版本,它将直接导出 'patches' 关键字下的所有补丁。
未定义版本的 conandata.yml

from conan.tools.files import export_conandata_patches
