conan cache¶
在本地缓存（配方和/或包）中执行文件操作。
conan cache path¶
$ conan cache path -h
usage: conan cache path [-h] [-f FORMAT] [--out-file OUT_FILE] [-v [V]]
[-cc CORE_CONF]
[--folder {export_source,source,build,metadata}]
reference
Show the path to the Conan cache for a given reference.
positional arguments:
reference Recipe reference or Package reference
options:
-h, --help show this help message and exit
-f FORMAT, --format FORMAT
Select the output format: json
--out-file OUT_FILE Write the output of the command to the specified file
instead of stdout.
-v [V] Level of detail of the output. Valid options from less
verbose to more verbose: -vquiet, -verror, -vwarning,
-vnotice, -vstatus, -v or -vverbose, -vv or -vdebug,
-vvv or -vtrace
-cc CORE_CONF, --core-conf CORE_CONF
Define core configuration, overwriting global.conf
values. E.g.: -cc core:non_interactive=True
--folder {export_source,source,build,metadata}
Path to show. The 'build' requires a package
reference. If the argument is not passed, it shows
'exports' path for recipe references and 'package'
folder for package references.
conan cache path 返回给定引用在缓存中的路径。根据引用，它可以返回配方的路径，也可以返回包二进制文件的路径。
假设我们已经在当前缓存中使用以下命令创建了一个包
$ conan new cmake_lib -d name=pkg -d version=0.1
$ conan create .
...
Requirements
pkg/0.1#cdc0d9d0e8f554d3df2388c535137d77 - Cache
Requirements
pkg/0.1#cdc0d9d0e8f554d3df2388c535137d77:2401fa1d188d289bb25c37cfa3317e13e377a351 - Build
现在我们有兴趣获取我们的 pkg/0.1 配方 conanfile.py 导出的路径
$ conan cache path pkg/0.1
<path to conan cache>/p/5cb229164ec1d245/e
$ ls <path to conan cache>/p/5cb229164ec1d245/e
conanfile.py conanmanifest.txt
默认情况下，如果未指定配方修订版本，则表示缓存中的“最新”修订版本。这也可以通过字面量 #latest 显式指定，并且任何配方修订版本都可以显式定义，以下命令与上述命令等效
$ conan cache path pkg/0.1#latest
<path to conan cache>/p/5cb229164ec1d245/e
# The recipe revision might be different in your case.
# Check the "conan create" output to get yours
$ conan cache path pkg/0.1#cdc0d9d0e8f554d3df2388c535137d77
<path to conan cache>/p/5cb229164ec1d245/e
除了配方文件夹之外，还有两个其他文件夹对于使用此配方生成的所有二进制文件都是通用的：“export_source”文件夹和“source”文件夹。两者都可以通过以下命令获取
$ conan cache path pkg/0.1 --folder=export_source
<path to conan cache>/p/5cb229164ec1d245/es
$ ls <path to conan cache>/p/5cb229164ec1d245/es
CMakeLists.txt include/ src/
$ conan cache path pkg/0.1 --folder=source
<path to conan cache>/p/5cb229164ec1d245/s
$ ls <path to conan cache>/p/5cb229164ec1d245/s
CMakeLists.txt include/ src/
在这种情况下，“source”文件夹的内容与“export_source”文件夹的内容相同，因为配方没有实现任何 source() 方法来检索代码或对代码执行任何其他操作，例如应用补丁。
默认情况下，配方修订版本将为 #latest，这与上述规则相同。
请注意，如果包不是从源代码构建的，例如当从服务器检索预编译的二进制文件时，这两个文件夹将不存在。
也可以通过提供 package_id 来获取二进制包的文件夹
# Your package_id might be different, it depends on the platform
# Check the "conan create" output to obtain yours
$ conan cache path pkg/0.1:2401fa1d188d289bb25c37cfa3317e13e377a351
<path to conan cache>/p/1cae77d6250c23b7/p
$ ls <path to conan cache>/p/1cae77d6250c23b7/p
conaninfo.txt conanmanifest.txt include/ lib/
如上所述，默认情况下，它将解析为“最新”配方修订版本和包修订版本。上面的命令等同于显式定义 #latest 或确切的修订版本。以下所有命令都与上面的命令等效
$ conan cache path pkg/0.1#latest:2401fa1d188d289bb25c37cfa3317e13e377a351
<path to conan cache>/p/1cae77d6250c23b7/p
$ conan cache path pkg/0.1#latest:2401fa1d188d289bb25c37cfa3317e13e377a351#latest
<path to conan cache>/p/1cae77d6250c23b7/p
$ conan cache path pkg/0.1#cdc0d9d0e8f554d3df2388c535137d77:2401fa1d188d289bb25c37cfa3317e13e377a351
<path to conan cache>/p/1cae77d6250c23b7/p
可以访问包含所有临时构建产物的“build”文件夹
$ conan cache path pkg/0.1:2401fa1d188d289bb25c37cfa3317e13e377a351 --folder=build
<path to conan cache>/p/1cae77d6250c23b7/b
ls -al <path to conan cache>/p/1cae77d6250c23b7/b
build/ CMakeLists.txt CMakeUserPresets.json conaninfo.txt include/ src/
同样，“build”文件夹仅在包是从源代码构建时才存在。
注意
最佳实践
此
conan cache path命令旨在用于最终检查缓存，但缓存包存储必须被视为只读。请勿修改、更改、移除或添加缓存中的文件。如果您使用此命令来获取工件的路径然后复制它们，请考虑使用
deployer代替。在一般情况下，不鼓励手动从缓存中提取工件。开发人员可以使用
conan list ... --format=compact以紧凑的方式获取完整的引用，可以将其复制并粘贴到conan cache path命令中
conan cache clean¶
$ conan cache clean -h
usage: conan cache clean [-h] [--out-file OUT_FILE] [-v [V]] [-cc CORE_CONF]
[-s] [-b] [-d] [-t] [-bs] [-p PACKAGE_QUERY]
[pattern]
Remove non-critical folders from the cache, like source, build and/or download
(.tgz store) ones.
positional arguments:
pattern Selection pattern for references to clean
options:
-h, --help show this help message and exit
--out-file OUT_FILE Write the output of the command to the specified file
instead of stdout.
-v [V] Level of detail of the output. Valid options from less
verbose to more verbose: -vquiet, -verror, -vwarning,
-vnotice, -vstatus, -v or -vverbose, -vv or -vdebug,
-vvv or -vtrace
-cc CORE_CONF, --core-conf CORE_CONF
Define core configuration, overwriting global.conf
values. E.g.: -cc core:non_interactive=True
-s, --source Clean source folders
-b, --build Clean build folders
-d, --download Clean download and metadata folders
-t, --temp Clean temporary folders
-bs, --backup-sources
Clean backup sources
-p PACKAGE_QUERY, --package-query PACKAGE_QUERY
Remove only the packages matching a specific query,
e.g., os=Windows AND (arch=x86 OR compiler=gcc)
此命令将删除所有临时文件夹，以及 Conan 在执行过程中生成的 source、build 和 download 文件夹。它将为 pattern 中传递的每个匹配引用执行此操作，除非提供了特定标志，在这种情况下，仅删除指定的文件夹。
示例:
移除所有非关键文件
$ conan cache clean "*"
移除所有临时文件
$ conan cache clean "*" --temp
移除
zlib配方的 download 文件夹$ conan cache clean "zlib/*" --download
移除除
zlib配方的 download 文件夹之外的所有内容$ conan cache clean "zlib/*" --source --build --temp
conan cache check-integrity¶
$ conan cache check-integrity -h
usage: conan cache check-integrity [-h] [--out-file OUT_FILE] [-v [V]]
[-cc CORE_CONF] [-p PACKAGE_QUERY]
pattern
Check the integrity of the local cache for the given references
positional arguments:
pattern Selection pattern for references to check integrity
for
options:
-h, --help show this help message and exit
--out-file OUT_FILE Write the output of the command to the specified file
instead of stdout.
-v [V] Level of detail of the output. Valid options from less
verbose to more verbose: -vquiet, -verror, -vwarning,
-vnotice, -vstatus, -v or -vverbose, -vv or -vdebug,
-vvv or -vtrace
-cc CORE_CONF, --core-conf CORE_CONF
Define core configuration, overwriting global.conf
values. E.g.: -cc core:non_interactive=True
-p PACKAGE_QUERY, --package-query PACKAGE_QUERY
Only the packages matching a specific query, e.g.,
os=Windows AND (arch=x86 OR compiler=gcc)
conan cache check-integrity 命令检查本地缓存中 Conan 包的完整性。这意味着如果 conanmanifest.txt 中包含的任何文件丢失或与该文件中声明的校验和不匹配，它将抛出错误。
例如，要验证整个 Conan 本地缓存的完整性，请执行
$ conan cache check-integrity "*"
mypkg/1.0: Integrity checked: ok
mypkg/1.0:454923cd42d0da27b9b1294ebc3e4ecc84020747: Integrity checked: ok
mypkg/1.0:454923cd42d0da27b9b1294ebc3e4ecc84020747: Integrity checked: ok
zlib/1.2.11: Integrity checked: ok
zlib/1.2.11:6fe7fa69f760aee504e0be85c12b2327c716f9e7: Integrity checked: ok
conan cache backup-upload¶
$ conan cache backup-upload -h
usage: conan cache backup-upload [-h] [--out-file OUT_FILE] [-v [V]]
[-cc CORE_CONF]
Upload all the source backups present in the cache

-vvv or -vtrace
-cc CORE_CONF, --core-conf CORE_CONF
Define core configuration, overwriting global.conf
values. E.g.: -cc core:non_interactive=True
conan cache backup-upload 将本地缓存中存在的所有源备份上传到备份服务器（不包括从 core.sources:exclude_urls conf 中列出的排除 URL 获取的备份），无论它们属于哪个包（如果有）。
conan cache save¶
$ conan cache save -h
usage: conan cache save [-h] [-f FORMAT] [--out-file OUT_FILE] [-v [V]]
[-cc CORE_CONF] [-l LIST] [--file FILE]
