## pip_repositories

<pre>

A placeholder method that will eventually pull in any dependencies
needed to install pip dependencies.

## pip_import

<pre>
pip_import(<a href="#pip_import.name">name</a>, <a href="#pip_import.requirements">requirements</a>)
</pre>

A rule for importing <code>requirements.txt</code> dependencies into Bazel.

This rule imports a <code>requirements.txt</code> file and generates a new
<code>requirements.bzl</code> file.  This is used via the <code>WORKSPACE</code>
pattern:
<pre><code>pip_import(
    name = "foo",
    requirements = ":requirements.txt",
)
load("@foo//:requirements.bzl", "pip_install")
pip_install()
</code></pre>

You can then reference imported dependencies from your <code>BUILD</code>
file with:
<pre><code>load("@foo//:requirements.bzl", "requirement")
py_library(
    name = "bar",
    ...
    deps = [
       "//my/other:dep",
       requirement("futures"),
       requirement("mock"),
    ],
)
</code></pre>

Or alternatively:
<pre><code>load("@foo//:requirements.bzl", "all_requirements")
py_binary(
    name = "baz",
    ...
    deps = [
       ":foo",
    ] + all_requirements,
)
</code></pre>
