conan profile detect

.. autocommand::
    :command: conan profile detect -h

Warning

The output of conan profile detect is not stable. It can change at any time in future Conan releases to adapt to latest tools, latest versions, or other changes in the environment. See :ref:`the Conan stability<stability>` section for more information.

You can create a new auto-detected profile for your configuration using:

$ conan profile detect
Found apple-clang 14.0
apple-clang>=13, using the major as version
Detected profile:
[settings]
arch=x86_64
build_type=Release
compiler=apple-clang
compiler.cppstd=gnu17
compiler.libcxx=libc++
compiler.version=14
os=Macos

WARN: This profile is a guess of your environment, please check it.
WARN: Defaulted to cppstd='gnu17' for apple-clang.
WARN: The output of this command is not guaranteed to be stable and can change in future Conan versions.
WARN: Use your own profile files for stability.
Saving detected profile to /Users/barbarians/.conan2/profiles/default

Be aware that if the profile already exists you have to use --force to overwrite it. Otherwise it will fail

$ conan profile detect
ERROR: Profile '/Users/carlosz/.conan2/profiles/default' already exists
$ conan profile detect --force
Found apple-clang 14.0
...
Saving detected profile to /Users/carlosz/.conan2/profiles/default

Note

Best practices It is not recommended to use conan profile detect in production. To guarantee reproducibility, it is recommended to define your own profiles, store them in a git repo or in a zip in a server, and distribute it to your team and CI machines with conan config install, together with other configuration like custom settings, custom remotes definition, etc.

conan profile list

.. autocommand::
    :command: conan profile list -h

$ conan profile list
Profiles found in the cache:
default
ios_base
ios_simulator
clang_15

conan profile path

.. autocommand::
    :command: conan

Use to get the profile location in your [CONAN_HOME] folder:

$ conan profile path default
/Users/barbarians/.conan2/profiles/default

conan profile show

.. autocommand::
    :command: conan profile show -h

Use :command:`conan profile show` to compute the resulting build and host profiles from the command line arguments. For example, combining different options and settings with the default profile or with any other profile using the pr:b or pr:h arguments:

$ conan profile show -s:h build_type=Debug -o:h shared=False
Host profile:
[settings]
arch=x86_64
build_type=Debug
compiler=apple-clang
compiler.cppstd=gnu17
compiler.libcxx=libc++
compiler.version=14
os=Macos
[options]
shared=False
[conf]


Build profile:
[settings]
arch=x86_64
build_type=Release
compiler=apple-clang
compiler.cppstd=gnu17
compiler.libcxx=libc++
compiler.version=14
os=Macos
[conf]

It's also useful to show the result of the evaluation of :ref:`jinja2 templates in the profiles<reference_config_files_profiles_rendering>`. For example, a profile like this:

[settings]
os = {{ {"Darwin": "Macos"}.get(platform.system(), platform.system()) }}

Check the evaluated profile:

$ conan profile show -pr:h=myprofile
Host profile:
[settings]
os=Macos
[conf]
...

The command can also output a json with the results:

$ conan profile show --format=json
