experimental_workspace_environment

Configuration of a "workspace" execution environment for specific platforms.

A "workspace" environment is a local environment which executes build processes within the repository and not in the usual execution sandbox. This is useful when interacting with third-party build orchestration tools which may not run correctly when run from within the Pants execution sandbox.

Environment configuration includes the platforms the environment is compatible with 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 experimental_workspace_environment may be defined in [environments-preview].names per platform, and when __local_workspace__ is specified as the environment, the experimental_workspace_environment that matches the current platform (if defined) will be selected.

Caching and reproducibility:

Pants' caching relies on all process being reproducible based solely on inputs in the repository. Processes executed in a workspace environment can easily accidentally read unexpected files, that aren't specified as a dependency. Thus, Pants puts that burden on you, the Pants user, to ensure a process output only depends on its specified input files, and doesn't read anything else.

If a process isn't reproducible, re-running a build from the same source code could fail unexpectedly, or give different output to an earlier build.

NOTE: This target type is EXPERIMENTAL and may change its semantics in subsequent Pants versions without a deprecation cycle.

Backend: pants.core

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.
