conan inspect¶
Warning
This feature is experimental and subject to breaking changes. See the Conan stability section for more information.
$ conan inspect -h
WARN: Downgrading cache from Conan 2.8.1 to 2.5.0
usage: conan inspect [-h] [-v [V]] [-cc CORE_CONF] [-f FORMAT]
[-r REMOTE | -nr] [-l LOCKFILE] [--lockfile-partial]
path
Inspect a conanfile.py to return its public fields.
positional arguments:
path Path to a folder containing a recipe (conanfile.py)
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
-f FORMAT, --format FORMAT
Select the output format: json
-r REMOTE, --remote REMOTE
Remote names. Accepts wildcards ('*' means all the
remotes available)
-nr, --no-remote Do not use remote, resolve exclusively in the cache
-l LOCKFILE, --lockfile LOCKFILE
Path to a lockfile. Use --lockfile="" to avoid
automatic use of existing 'conan.lock' file
--lockfile-partial Do not raise an error if some dependency is not found
in lockfile
The conan inspect command shows the public attributes of any recipe (conanfile.py) as follows:
$ conan inspect .

conan inspect
evaluates recipe methods such as set_name()
and set_version()
,
and is capable of resolving python_requires
dependencies (which can be locked with the --lockfile
argument),
so its base methods will also be properly executed.
Note
The --remote
argument is used only for fetching remote python_requires
in cases where they are needed,
not to inspect recipes from a remote. Use conan graph info for such cases.
The conan inspect ... --format=json returns a JSON output format in stdout
(which can be redirected to a file) with the following structure:
$ conan inspect . --format=json

does not list any requirements listed in the requirements()
method,
only those present in the requires
attribute will be shown.
