View Source mix deps (Mix v1.12.0-rc.1)
Lists all dependencies and their status.
Dependencies must be specified in the mix.exs
file in one of
the following formats:
{app, requirement}
{app, opts}
{app, requirement, opts}
Where:
- app is an atom
- requirement is a
Version
requirement or a regular expression - opts is a keyword list of options
For example:
{:plug, ">= 0.4.0"}
{:gettext, git: "https://github.com/elixir-lang/gettext.git", tag: "0.1"}
{:local_dependency, path: "path/to/local_dependency"}
By default, dependencies are fetched using the Hex package manager:
{:plug, ">= 0.4.0"}
By specifying such dependencies, Mix will automatically install Hex (if it wasn't previously installed) and download a package suitable to your project. Note Hex expects the dependency requirement to always be given and it will warn otherwise.
Mix also supports Git and path dependencies:
{:foobar, git: "https://github.com/elixir-lang/foobar.git", tag: "0.1"}
{:foobar, path: "path/to/foobar"}
And also in umbrella dependencies:
{:my_app, in_umbrella: true}
Path and in umbrella dependencies are automatically recompiled by
the parent project whenever they change. While fetchable dependencies,
like the ones using :git
, are recompiled only when fetched/updated.
The dependencies' versions are expected to be formatted according to
Semantic Versioning and the requirements must be specified as defined
in the Version
module.
Options
Below we provide a more detailed look into the available options.
Dependency definition options
:app
- when set tofalse
, does not read the app file for this dependency. By default, the app file is read:env
- the environment (as an atom) to run the dependency on; defaults to:prod
:compile
- a command (string) to compile the dependency; defaults to amix
,rebar
ormake
command:optional
- marks the dependency as optional. In such cases, the current project will always include the optional dependency but any other project that depends on the current project won't be forced to use the optional dependency. However, if the other project includes the optional dependency on its own, the requirements and options specified here will also be applied. Optional dependencies will not be started by the application.:only
- the dependency is made available only in the given environments, useful when declaring dev- or test-only dependencies; by default the dependency will be available in all environments. The value of this option can either be a single environment (like:dev
) or a list of environments (like[:dev, :test]
):targets
- the dependency is made available only for the given targets. By default the dependency will be available in all environments. The value of this option can either be a single target (like:host
) or a list of environments (like[:host, :rpi3]
):override
- if set totrue
the dependency will override any other definitions of itself by other dependencies:manager
- Mix can also compile Rebar, Rebar3 and makefile projects and can fetch sub dependencies of Rebar and Rebar3 projects. Mix will try to infer the type of project but it can be overridden with this option by setting it to:mix
,:rebar3
,:rebar
or:make
. In case there are conflicting definitions, the first manager in the list above will be picked up. For example, if a dependency is found with:rebar3
and:rebar
managers in different part of the trees,:rebar3
will be automatically picked. You can find the manager by runningmix deps
and override it by setting the:override
option in a top-level project.:runtime
- whether the dependency is part of runtime applications. If the:applications
key is not provided indef application
in yourmix.exs
file, Mix will automatically include all dependencies as a runtime application, except ifruntime: false
is given. Defaults to true.:system_env
- an enumerable of key-value tuples of binaries to be set as environment variables when loading or compiling the dependency
Git options (:git
)
:git
- the Git repository URI:github
- a shortcut for specifying Git repos from GitHub, uses:git
:ref
- the reference to checkout (may be a branch, a commit SHA or a tag):branch
- the Git branch to checkout:tag
- the Git tag to checkout:submodules
- whentrue
, initialize submodules for the repo:sparse
- checkout a single directory inside the Git repository and use it as your Mix dependency. Search "sparse Git checkouts" for more information.
If your Git repository requires authentication, such as basic username:password HTTP authentication via URLs, it can be achieved via Git configuration, keeping the access rules outside of source control.
git config --global url."https://YOUR_USER:YOUR_PASS@example.com/".insteadOf "https://example.com/"
For more information, see the git config
documentation:
https://git-scm.com/docs/git-config#git-config-urlltbasegtinsteadOf
Path options (:path
)
:path
- the path for the dependency:in_umbrella
- whentrue
, sets a path dependency pointing to "../#{app}", sharing the same environment as the current application
Hex options (:hex
)
See the Hex usage documentation for Hex options.
Deps task
mix deps
task lists all dependencies in the following format:
APP VERSION (SCM) (MANAGER)
[locked at REF]
STATUS
For dependencies satisfied by Hex, REF
is the package checksum.
For dependencies satisfied by git, REF
is the commit object name,
and may include branch or tag information.
It supports the following options:
--all
- lists all dependencies, regardless of specified environment
