$ conan alias [-h] reference target
Creates and exports an ‘alias package recipe’.
An “alias” package is a symbolic name (reference) for another package (target). When some package depends on an alias, the target one will be retrieved and used instead, so the alias reference, the symbolic name, does not appear in the final dependency graph.
positional arguments: reference Alias reference. e.g.: mylib/1.X@user/channel target Target reference. e.g.: mylib/1.12@user/channel optional arguments: -h, --help show this help message and exit
$ conan alias hello/0.X@user/testing hello/0.1@user/testing
Creates and exports a package recipe for
hello/0.X@user/testing with the following content:
from conans import ConanFile class AliasConanfile(ConanFile): alias = "hello/0.1@user/testing"
Such package recipe acts as a “proxy” for the aliased reference. Users depending on
hello/0.X@user/testing will actually use version
hello/0.1@user/testing. The alias package
reference will not appear in the dependency graph at all. It is useful to define symbolic names, or
behaviors like “always depend on the latest minor”, but defined upstream instead of being defined
The “alias” package should be uploaded to servers in the same way as regular package recipes, in order to enable usage from servers.
From Conan 1.39, a new experimental explicit syntax for requiring alias packages has been
introduced, designed to supersede the current one in Conan 2.0, in the form
``requires = "pkg/(latest)@user/testing".
