conan report¶
conan report
命令包含子命令,用于返回有关软件包和库的信息。
$ conan report -h
usage: conan report [-h] [-v [V]] [-cc CORE_CONF] [--out-file OUT_FILE]
{diff} ...
Gets information about the recipe and its sources.
positional arguments:
{diff} sub-command help
diff Get the difference between two recipes with their
sources. It can be used to compare two different
versions of the same recipe, or two different recipe
revisions. Each old/new recipe can be specified by a
path to a conanfile.py and a companion reference, or
by a reference only. If only a reference is specified,
it will be searched in the local cache, or downloaded
from the specified remotes. If no revision is
specified, the latest revision will be used.
options:
-h, --help show this help message and exit
-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
--out-file OUT_FILE Write the output of the command to the specified file
instead of stdout.
conan report diff¶
$ conan report diff -h
usage: conan report diff [-h] [-f FORMAT] [--out-file OUT_FILE] [-v [V]]
[-cc CORE_CONF] [-op OLD_PATH] -or OLD_REFERENCE
[-np NEW_PATH] -nr NEW_REFERENCE [-r REMOTE]
Get the difference between two recipes with their sources. It can be used to
compare two different versions of the same recipe, or two different recipe
revisions. Each old/new recipe can be specified by a path to a conanfile.py
and a companion reference, or by a reference only. If only a reference is
specified, it will be searched in the local cache, or downloaded from the
specified remotes. If no revision is specified, the latest revision will be
used.
options:
-h, --help show this help message and exit
-f FORMAT, --format FORMAT
Select the output format: json, html
--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
-op OLD_PATH, --old-path OLD_PATH
Path to the old recipe if comparing a local recipe is
desired
-or OLD_REFERENCE, --old-reference OLD_REFERENCE
Old reference, e.g. 'mylib/1.0'. If used on its own,
it can contain a revision, which will be resolved to
the latest one if not provided, but it will be ignored
if a path is specified. If used with a path, it will
be used to create the reference for the recipe to be
compared.
-np NEW_PATH, --new-path NEW_PATH
Path to the new recipe if comparing a local recipe is
desired
-nr NEW_REFERENCE, --new-reference NEW_REFERENCE
New reference, e.g. 'mylib/1.0'. If used on its own,
it can contain a revision, which will be resolved to
the latest one if not provided, but it will be ignored
if a path is specified. If used with a path, it will
be used to create the reference for the recipe to be
compared.
-r REMOTE, --remote REMOTE
Look in the specified remote or remotes server
conan report diff
命令获取两个配方之间的差异,并比较它们的源代码。此功能允许您比较同一配方的两个版本,或两个完全不同的配方。每个配方(旧的和新的)可以通过两种方式之一进行识别:提供其 conanfile.py
的路径及其引用,或仅指定引用。
当只给定一个引用时,Conan 将首先在本地缓存中搜索配方;如果未找到,它将尝试从配置的远程下载。如果未明确提供修订版,Conan 将默认使用最新的可用修订版。
示例¶
远程引用与远程引用¶
如果我们想比较 mylib 在 my-remote 远程上可用的 1.0 和 2.0 版本,命令将是
$ conan report diff --old-reference="mylib/1.0" --new-reference="mylib/2.0" -r=my-remote
远程引用与本地引用¶
假设我们正在修改配方或添加新版本,并且我们想将我们的更改与远程上的一个版本进行比较。不在远程上的版本需要配方路径才能进行比较。如果这是我们正在修改的旧版本,并且它在远程中未找到,我们将使用 --old-path
$ conan report diff --old-reference="mylib/1.0" --old-path="path/to/recipe" --new-reference="mylib/2.0"
另一方面,如果我们正在修改的是新版本,那么我们将使用 --new-path
$ conan report diff --old-reference="mylib/1.0" --new-reference="mylib/2.0" --new-path="path/to/recipe"
本地引用与本地引用¶
最后,如果我们要修改两个版本,我们需要提供两个路径。它们可能相同,也可能不同。
$ conan report diff --old-reference="mylib/1.0" --old-path="path/to/recipe" --new-reference="mylib/2.0" --new-path="path/to/recipe"
指定修订版¶
此命令允许您指定要比较的软件包的修订版。默认情况下,它使用最新修订版,但通过提供修订版,您可以精确地指定要比较的软件包。这使得比较两个相同版本但不同修订版的情况成为可能,以检查它们之间的差异。
$ conan report diff --old-reference="mylib/1.0#oldrev" --new-reference="mylib/1.0#newrev"
可用格式化程序¶
文本格式化程序¶
默认情况下,它显示此格式,这是 git diff
在软件包之间提供的格式。
JSON 格式化程序¶
您可以获取 JSON 格式的结果,提供结构化的输出,非常适合其他脚本使用。
$ conan report diff --old-reference="mylib/1.0" --new-reference="mylib/2.0" --format=json
HTML 格式化程序¶
HTML 格式会在单个 HTML 文件中生成一个小型、自包含的静态网页。此页面让您可以方便地可视化配方中的更改以及库源文件中的更改。它包含用于包含和排除关键字的过滤器以及所有已更改文件的快捷方式。
$ conan report diff --old-reference="zlib/1.3" --new-reference="mylib/1.3.1" --format=html > diff.html
