known_versions

--buf-known-versions="['<str>', '<str>', ...]"

PANTS_BUF_KNOWN_VERSIONS

default:

[
  "v1.3.0|linux_arm64 |fbfd53c501451b36900247734bfa4cbe86ae05d0f51bc298de8711d5ee374ee5|13940828",

]


Known versions to verify downloads against.

Each element is a pipe-separated string of version|platform|sha256|length, 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

E.g., 3.1.2|macos_x86_64|6d0f18cd84b918c7b3edd0203e75569e0c7caecb1367bbbe409b44e28514f5be|42813.

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

url_template

--buf-url-template=<str>

PANTS_BUF_URL_TEMPLATE

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-{version}-{platform}.zip.

url_platform_mapping

--buf-url-platform-mapping="{'key1': val1, 'key2': val2, ...}"

PANTS_BUF_URL_PLATFORM_MAPPING

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.

use_unsupported_version

--buf-use-unsupported-version=<UnsupportedVersionUsage>

PANTS_BUF_USE_UNSUPPORTED_VERSION

one of: error, warning

default: error


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

Supported Buf versions: unspecified

config

--buf-config=<file_option>

PANTS_BUF_CONFIG

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

default: True

If true, Pants will include any relevant root config files during runs (buf.yaml, buf.lock, buf.gen.yaml and buf.work.yaml).

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

Deprecated options

None
