buf

A linter and formatter for Protocol Buffers (https://github.com/bufbuild/buf).

Backend: pants.backend.codegen.protobuf.lint.buf

Config section: [buf]

Basic options​

format_args​

--buf-format-args="[<shell_str>, <shell_str>, ...]"
PANTS_BUF_FORMAT_ARGS
pants.toml
[buf]
format_args = [
    <shell_str>,
    <shell_str>,
    ...,
]
default: []

Arguments to pass directly to Buf, e.g. --buf-args='--error-format json'.

format_skip​

--[no-]buf-format-skip
PANTS_BUF_FORMAT_SKIP
pants.toml
[buf]
format_skip = <bool>
default: False

If true, don't use Buf when running pants fmt and pants lint.

lint_args​

--buf-lint-args="[<shell_str>, <shell_str>, ...]"
PANTS_BUF_LINT_ARGS
pants.toml
[buf]
lint_args = [
    <shell_str>,
    <shell_str>,
    ...,
]
default: []

Arguments to pass directly to Buf, e.g. --buf-args='--error-format json'.

lint_skip​

--[no-]buf-lint-skip
PANTS_BUF_LINT_SKIP
pants.toml
[buf]
lint_skip = <bool>
default: False

If true, don't use Buf when running pants lint.

Advanced options​

config​

--buf-config=<file_option>
PANTS_BUF_CONFIG
pants.toml
[buf]
config = <file_option>
default: None

Path to a config file understood by Buf (https://docs.buf.build/configuration/overview).

Setting this option will disable [buf].config_discovery. Use this option if the config is located in a non-standard location.

config_discovery​

--[no-]buf-config-discovery
PANTS_BUF_CONFIG_DISCOVERY
pants.toml
[buf]
config_discovery = <bool>
default: True

If true, Pants will include any relevant root config files during runs (buf.yaml). If the json format is preferred, the path to the buf.json file should be provided in the config option.

Use [buf].config instead if your config is in a non-standard location.

known_versions​

--buf-known-versions="['<str>', '<str>', ...]"
PANTS_BUF_KNOWN_VERSIONS
pants.toml
[buf]
known_versions = [
    '<str>',
    '<str>',
    ...,
]
default: 
[
  "v1.3.0|linux_arm64 |fbfd53c501451b36900247734bfa4cbe86ae05d0f51bc298de8711d5ee374ee5|13940828",

  "v1.3.0|macos_x86_64|3b6bd2e5a5dd758178aee01fb067261baf5d31bfebe93336915bfdf7b21928c4|15955291"
]

Known versions to verify downloads against.

Each element is a pipe-separated string of version|platform|sha256|length or version|platform|sha256|length|url_override, where:

  • version is the version string
  • platform is one of [linux_arm64,linux_x86_64,macos_arm64,macos_x86_64]
  • sha256 is the 64-character hex representation of the expected sha256 digest of the download file, as emitted by shasum -a 256
  • length is the expected length of the download file in bytes, as emitted by wc -c
  • (Optional) url_override is a specific url to use instead of the normally generated url for this version

E.g., 3.1.2|macos_x86_64|6d0f18cd84b918c7b3edd0203e75569e0c7caecb1367bbbe409b44e28514f5be|42813. and 3.1.2|macos_arm64 |aca5c1da0192e2fd46b7b55ab290a92c5f07309e7b0ebf4e45ba95731ae98291|50926|https://example.mac.org/bin/v3.1.2/mac-aarch64-v3.1.2.tgz.

Values are space-stripped, so pipes can be indented for readability if necessary.

url_platform_mapping​

--buf-url-platform-mapping="{'key1': val1, 'key2': val2, ...}"
PANTS_BUF_URL_PLATFORM_MAPPING
pants.toml
[buf.url_platform_mapping]
key1 = val1
key2 = val2
...
default: 
{
  "linux_arm64": "Linux-aarch64",
  "linux_x86_64": "Linux-x86_64",
  "macos_arm64": "Darwin-arm64",
  "macos_x86_64": "Darwin-x86_64"
}

A dictionary mapping platforms to strings to be used when generating the URL to download the tool.

In --url-template, anytime the {platform} string is used, Pants will determine the current platform, and substitute {platform} with the respective value from your dictionary.

For example, if you define {"macos_x86_64": "apple-darwin", "linux_x86_64": "unknown-linux"}, and run Pants on Linux with an intel architecture, then {platform} will be substituted in the --url-template option with unknown-linux.

url_template​

--buf-url-template=<str>
PANTS_BUF_URL_TEMPLATE
pants.toml
[buf]
url_template = <str>
default: https://github.com/bufbuild/buf/releases/download/{version}/buf-{platform}.tar.gz

URL to download the tool, either as a single binary file or a compressed file (e.g. zip file). You can change this to point to your own hosted file, e.g. to work with proxies or for access via the filesystem through a file:$abspath URL (e.g. file:/this/is/absolute, possibly by templating the buildroot in a config file).

Use {version} to have the value from --version substituted, and {platform} to have a value from --url-platform-mapping substituted in, depending on the current platform. For example, https://github.com/.../protoc-&#123;version&#125;-&#123;platform&#125;.zip.

use_unsupported_version​

--buf-use-unsupported-version=<UnsupportedVersionUsage>
PANTS_BUF_USE_UNSUPPORTED_VERSION
pants.toml
[buf]
use_unsupported_version = <UnsupportedVersionUsage>
one of: error, warning
default: error

What action to take in case the requested version of Buf is not supported.

Supported Buf versions: unspecified

version​

--buf-version=<str>
PANTS_BUF_VERSION
pants.toml
[buf]
version = <str>
default: v1.3.0

Use this version of Buf.
