This implements the ``jsonnet`` language for Gazelle.



Setup

-----



Running Gazelle with Bazel

~~~~~~~~~~~~~~~~~~~~~~~~~~



To use Gazelle in a new project, add the ``bazel_gazelle`` repository and its

dependencies to your WORKSPACE file and call ``gazelle_dependencies``. It

should look like this:



.. code:: bzl



    load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")



    http_archive(

        name = "io_bazel_rules_go",

        urls = [

            "https://storage.googleapis.com/bazel-mirror/github.com/bazelbuild/rules_go/releases/download/v0.20.1/rules_go-v0.20.1.tar.gz",

            "https://github.com/bazelbuild/rules_go/releases/download/v0.20.1/rules_go-v0.20.1.tar.gz",

        ],

        sha256 = "842ec0e6b4fbfdd3de6150b61af92901eeb73681fd4d185746644c338f51d4c0",

    )



    http_archive(

        name = "bazel_gazelle",

        urls = [

            "https://storage.googleapis.com/bazel-mirror/github.com/bazelbuild/bazel-gazelle/releases/download/v0.19.0/bazel-gazelle-v0.19.0.tar.gz",

            "https://github.com/bazelbuild/bazel-gazelle/releases/download/v0.19.0/bazel-gazelle-v0.19.0.tar.gz",

        ],

        sha256 = "41bff2a0b32b02f20c227d234aa25ef3783998e5453f7eade929704dcff7cd4b",

    )



    load("@io_bazel_rules_go//go:deps.bzl", "go_rules_dependencies", "go_register_toolchains")



    go_rules_dependencies()



    go_register_toolchains()



    load("@bazel_gazelle//:deps.bzl", "gazelle_dependencies")



    gazelle_dependencies()



    load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")



    git_repository(

        name = "jsonnet_gazelle",

        branch = "master",

        remote = "https://github.com/vmware/jsonnet-lang-for-gazelle",

    )



Add the code below to the BUILD or BUILD.bazel file in the root directory of

your repository to build a gazelle binary including the Jsonnet language.



.. code:: bzl



    load("@bazel_gazelle//:def.bzl", "DEFAULT_LANGUAGES", "gazelle", "gazelle_binary")



    gazelle_binary(

        name = "gazelle_jsonnet_binary",

        languages = DEFAULT_LANGUAGES + [

            "@jsonnet_gazelle//language/jsonnet:go_default_library",

        ],

        visibility = ["//visibility:public"],

    )



    load("@io_bazel_rules_jsonnet//jsonnet:jsonnet.bzl", "jsonnet_library")



    gazelle(

        name = "gazelle",

        gazelle = "//:gazelle_jsonnet_binary",

    )



After adding this code, you can run Gazelle with Bazel.



.. code::



  $ bazel run //:gazelle



This will generate new BUILD.bazel files for your project. You can run the same

command in the future to update existing BUILD.bazel files to include new source

files.



You can pass additional arguments to Gazelle after a ``--`` argument.



.. code::



  $ bazel run //:gazelle -- -jsonnet_ignore_folders=scripts



Directives

~~~~~~~~~~



Gazelle can be configured with *directives*, which are written as top-level

comments in build files. Most options that can be set on the command line

can also be set using directives. Some options can only be set with

directives.



Directive comments have the form ``# gazelle:key value``.



Example

^^^^^^^



.. code:: bzl



  load("@io_bazel_rules_jsonnet//jsonnet:jsonnet.bzl", "jsonnet_library")



  # gazelle:jsonnet_ignore_folders scripts



  gazelle(

      name = "gazelle_jsonnet",

      gazelle = "//:gazelle_jsonnet_binary",

  )



Directives apply in the directory where they are set *and* in subdirectories.

This means, for example, if you set ``# gazelle:jsonnet_ignore_folders`` in the build file

in your project's root directory, it affects your whole project. If you

set it in a subdirectory, it only affects rules in that subtree.



The following directives are recognized:



+-----------------------------------------------------+--------------------------------------+

| **Directive**                                       | **Default value**                    |

+=====================================================+======================================+

| :direc:`# gazelle:jsonnet_ignore_folders`           | none                                 |

+-----------------------------------------------------+--------------------------------------+

| Comma-separated list of folders that should not be processed. If not specified, Gazelle    |

| will process all the folders.                                                              |

+-----------------------------------------------------+--------------------------------------+
