Tools are all things that can be imported and used in Conan recipes.
This is the current design for Conan 2.0, and these will be the supported tools. Only the tools documented in this section will be available in Conan 2.0.
Some of the features used in this section are still under development, while they are recommended and usable and we will try not to break them in future releases, some breaking changes might still happen if necessary to prepare for the Conan 2.0 release.
Most of the utilities defined in “conan.tools” will require very soon to define both the “host” and “build” profiles. It is very recommended to start defining both profiles immediately to avoid future breaking. Furthermore, some features, like trying to cross-compile might not work at all if the “build” profile is not provided.
The import path is always like:
from conan.tools.cmake import CMakeToolchain, CMakeDeps, CMake
from conan.tools.microsoft import MSBuildToolchain, MSBuildDeps, MSBuild
The main guidelines are:
Imports must be in the form
from conan.tools.xxx import yyy, or
from conan.tools import xxx. Do not use
from conan import toolsnor
from conan.tools.xxx.yyy import zzz.
Everything that recipes can use belong to
from conan.tools. Any other import is private implementation and shouldn’t be used in recipes (except
from conan import ConanFileand
Only documented tools with explicitly documented imports can be used in recipes. Do not use any other import not found in this section of the documentation, even if they are in the
