local_environment

---

Configuration of a local execution environment for specific platforms.

Environment configuration includes the platforms the environment is compatible with, and optionally a fallback environment, along with environment-aware options (such as environment variables and search paths) used by Pants to execute processes in this environment.

To use this environment, map this target's address with a memorable name in [environments-preview].names. You can then consume this environment by specifying the name in the environment field defined on other targets.

Only one local_environment may be defined in [environments-preview].names per platform, and when __local__ is specified as the environment, the local_environment that matches the current platform (if defined) will be selected.

apache_thrift_thrift_search_paths

Iterable[str] | None

default: None

backend: pants.backend.codegen.thrift.apache.python

Overrides the default value from the option [apache-thrift].thrift_search_paths when this environment target is active.

compatible_platforms

Iterable[str] | None

default: ('linux_arm64', 'linux_x86_64', 'macos_arm64', 'macos_x86_64')

Which platforms this environment can be used with.

This is used for Pants to automatically determine which environment target to use for the user's machine when the environment is set to the special value __local__. Currently, there cannot be more than one environment target registered in [environments-preview].names for a particular platform. If there is no environment target for a certain platform, Pants will use the options system instead to determine environment variables and executable search paths.

description

str | None

default: None

A human-readable description of the target.

Use /home/josh/work/scie-pants/dist/pants list --documented :: to see all targets with descriptions.

docker_env_vars

Iterable[str] | None

default: None

backend: pants.backend.docker

Overrides the default value from the option [docker].env_vars when this environment target is active.

docker_executable_search_paths

Iterable[str] | None

default: None

backend: pants.backend.docker

Overrides the default value from the option [docker].executable_search_paths when this environment target is active.

fallback_environment

str | None

default: None

The environment to fallback to when this local environment cannot be used because the field compatible_platforms is not compatible with the local host.

Must be an environment name from the option [environments-preview].names, the special string __local__ to use the relevant local environment, or the Python value None to error when this specific local environment cannot be used.

Tip: when targeting Linux, it can be particularly helpful to fallback to a docker_environment or remote_environment target. That allows you to prefer using the local host when possible, which often has less overhead (particularly compared to Docker). If the local host is not compatible, then Pants will use Docker or remote execution to still run in a similar environment.

Iterable[str] | None

default: None

backend: pants.backend.experimental.go

Overrides the default value from the option [golang].cgo_tool_search_paths when this environment target is active.
