worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:

stating that You changed the files; and

distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.

agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

kazel - a BUILD file generator for go and bazel
===============================================
Requirements:
#############
* Your project must be somewhat compatible with go tool because
kazel uses go tool to parse your import tree.
* You must have a **GOPATH** and **GOROOT** setup and your project must
be in the correct location in your **GOPATH**.
* Your ``./vendor`` directory may not contain ``BUILD`` files.
Usage:
######
1. Get kazel by running ``go get k8s.io/repo-infra/kazel``.
2. Create a ``.kazelcfg.json`` in the root of the repository. For the
kazel repository, the ``.kazelcfg.json`` would look like:
.. code-block:: json
{
"GoPrefix": "k8s.io/repo-infra",
"SrcDirs": [
"./kazel"
],
"SkippedPaths": [
".*foobar(baz)?.*$"
]
}
3. Run kazel:
.. code-block:: bash
$ kazel -root=$GOPATH/src/k8s.io/repo-infra
Defaults:
#########
* **SrcDirs** in ``.kazelcfg.json`` defaults to ``["./"]``
* ``-root`` option defaults to the current working directory
Automanagement:
###############
kazel reconciles rules that have the "**automanaged**" tag. If
you no longer want kazel to manage a rule, you can remove the
**automanaged** tag and kazel will no longer manage that rule.
kazel only manages srcs, deps, and library attributes of a
rule after initial creation so you can add and managed other
attributes like data and copts and kazel will respect your
changes.
kazel automatically formats all ``BUILD`` files in your repository
except for those matching **SkippedPaths**.
Adding "sources" rules:
#######################
If you set "**AddSourcesRules**": ``true`` in your ``.kazelcfg.json``,
kazel will create "**package-srcs**" and "**all-srcs**" rules in every
package.
The "**package-srcs**" rule is a glob matching all files in the
package recursively, but not any files owned by packages in
subdirectories.
The "**all-srcs**" rule includes both the "**package-srcs**" rule and
the "**all-srcs**" rules of all subpackages; i.e. **//:all-srcs** will
include all files in your repository.
The "**package-srcs**" rule defaults to private visibility,
since it is safer to depend on the "**all-srcs**" rule: if a
subpackage is added, the "**package-srcs**" rule will no longer
include those files.
You can remove the "**automanaged**" tag from the "**package-srcs**"
rule if you need to modify the glob (such as adding excludes).
It's recommended that you leave the "**all-srcs**" rule
automanaged.
Validating BUILD files in CI:
#############################
If you run kazel with ``--validate``, it will not update any ``BUILD`` files, but it
will exit nonzero if any ``BUILD`` files are out-of-date. You can add ``--print-diff``
to print out the changes needed.
