Test support for writing Pants plugins.
Project description
Pants is an Apache2 licensed build tool written in Python and Rust.
The latest documentation can be found at pantsbuild.org.
2.16.x Release Series
What's New
BUILD files
The new env function in BUILD files allows access to environment variables in BUILD files.
Backends
Python
The Python backend has two new linters:
pydocstyle is now supported for linting Python doc strings. Enable the
pants.backend.python.lint.pydocstyle backend to add this support.
ruff is now supported for linting and formatting Python code. Enable the
pants.backend.experimental.python.lint.ruff backend to add this support.
Go
The Go backend has received a large number of changes in order to be ready for Go v1.20 and to make continued progress on stabilizing the Go backend.
The main change is that Pants will now compile Go SDK packages from scratch and no longer rely on the prebuilt package archives distributed with the Go SDK. Go v1.20 will no longer ship with those prebuilt package archives, and so this change was necessary for Pants to continue to work with Go v1.20 and later releases. (It is also a correctness issue since Pants will now be able to apply compiler options consistently when building Go SDK packages.)
The Pants team would appreciate if the community could try out 2.16.x with your Go code as an additional check to ensure there are no regressions.
The Go backend also now supports:
- Environments are supported via the
environmentfield available now ongo_binarytargets. - Code coverage can now analyze coverage for packages beyond just the package under test via the new
--go-test-cover-packagesoption. - Numerous bug fixes to the Cgo support.
- Race detector is supported via the
racefield now available ongo_binarytargets. - Compiler and other flags may be set via the
compiler_flags,linker_flags, andassembler_flagsfields available on various target types.
Shell
A new experimental_test_shell_command target type has been added to allow defining arbitrary shell commands
as tests which can be invoked using the ./pants test goal.
experimental_shell_command and experimental_run_shell_command have graduated to no longer have their experimental_ prefixes.
shell_command now supports the environment field for running in non-local environments.
New: Preamble
The new "preamble" plugin allows linting files to ensure they start with specific text. Enable the
pants.backend.tools.preamble backend to add this support.
New: CUE
Pants now supports the CUE language for defining, generating, and validating configuration data.
Enable the pants.backend.experimental.cue backend to add this support.
