protobuf_source

A single Protobuf file used to generate various languages.
See [Protobuf and gRPC](🔗﻿).
## <code>dependencies</code>
<span style="color: purple">type: <code>Iterable[str] | None</code></span>
<span style="color: green">default: <code>None</code></span>
Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib'].
Alternatively, you may include file names. Pants will find which target owns that file, and create a new target from that which only includes the file in its `sources` field. For files relative to the current BUILD file, prefix with `./`; otherwise, put the full path, e.g. ['./sibling.txt', 'resources/demo.json'].
You may exclude dependencies by prefixing with `!`, e.g. `['!helloworld/subdir:lib', '!./sibling.txt']`. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.
## <code>description</code>
<span style="color: purple">type: <code>str | None</code></span>
<span style="color: green">default: <code>None</code></span>
A human-readable description of the target.
Use `./pants list --documented ::` to see all targets with descriptions.
## <code>grpc</code>
<span style="color: purple">type: <code>bool</code></span>
<span style="color: green">default: <code>False</code></span>
Whether to generate gRPC code or not.
## <code>python_interpreter_constraints</code>
<span style="color: purple">type: <code>Iterable[str] | None</code></span>
<span style="color: green">default: <code>None</code></span>
The Python interpreters this code is compatible with.
Each element should be written in pip-style format, e.g. `CPython==2.7.*` or `CPython>=3.6,<4`. You can leave off `CPython` as a shorthand, e.g. `>=2.7` will be expanded to `CPython>=2.7`.
Specify more than one element to OR the constraints, e.g. `['PyPy==3.7.*', 'CPython==3.7.*']` means either PyPy 3.7 _or_ CPython 3.7.
If the field is not set, it will default to the option `[python].interpreter_constraints`.
See [Interpreter compatibility](🔗﻿) for how these interpreter constraints are merged with the constraints of dependencies.
## <code>python_source_root</code>
<span style="color: purple">type: <code>str | None</code></span>
<span style="color: green">default: <code>None</code></span>
The source root to generate Python sources under.
If unspecified, the source root the `protobuf_sources` is under will be used.
## <code>source</code>
<span style="color: purple">type: <code>str</code></span>
<span style="color: green">required</span>
A single file that belongs to this target.
Path is relative to the BUILD file's directory, e.g. `source='example.ext'`.
## <code>tags</code>
<span style="color: purple">type: <code>Iterable[str] | None</code></span>
<span style="color: green">default: <code>None</code></span>
Arbitrary strings to describe a target.
For example, you may tag some test targets with 'integration_test' so that you could run `./pants --tag='integration_test' test ::` to only run on targets with that tag.
