Options for Golang support.

Backend: pants.backend.experimental.go

Config section: [golang]

Basic options

cgo_enabled

--[no-]golang-cgo-enabled
PANTS_GOLANG_CGO_ENABLED

pants.toml

[golang]
cgo_enabled = <bool>

default: True

Enable Cgo support, which allows Go and C code to interact. This option must be enabled for any packages making use of Cgo to actually be compiled with Cgo support.

TODO: Future Pants changes may also require enabling Cgo via fields on relevant Go targets. See https://github.com/pantsbuild/pants/issues/16833.

See https://go.dev/blog/cgo and https://pkg.go.dev/cmd/cgo for additional information about Cgo.

cgo_tool_search_paths

--golang-cgo-tool-search-paths="['<str>', '<str>', ...]"
PANTS_GOLANG_CGO_TOOL_SEARCH_PATHS

pants.toml

[golang]
cgo_tool_search_paths = [
    '<str>',
    '<str>',
    ...,
]

default:

[
  "<PATH>"
]

A list of paths to search for tools needed by CGo (e.g., gcc, g++).

Specify absolute paths to directories with tools needed by CGo , e.g. /usr/bin. Earlier entries will be searched first.

The following special strings are supported:

• <PATH>, the contents of the PATH environment variable

Can be overriden by fieldgolang_cgo_tool_search_paths on local_environment, docker_environment, or remote_environmenttargets.

go_search_paths

--golang-go-search-paths="['<str>', '<str>', ...]"
PANTS_GOLANG_GO_SEARCH_PATHS

pants.toml

[golang]
go_search_paths = [
    '<str>',
    '<str>',
    ...,
]

default:

[
  "<PATH>"
]

A list of paths to search for Go.

Specify absolute paths to directories with the go binary, e.g. /usr/bin. Earlier entries will be searched first.

The following special strings are supported:

• <PATH>, the contents of the PATH environment variable
• <ASDF>, all Go versions currently configured by ASDF (asdf shell, ${HOME}/.tool-versions), with a fallback to all installed versions
• <ASDF_LOCAL>, the ASDF interpreter with the version in BUILD_ROOT/.tool-versions

Can be overriden by fieldgolang_go_search_paths on local_environment, docker_environment, or remote_environmenttargets.

minimum_expected_version

--golang-minimum-expected-version=<str>
PANTS_GOLANG_MINIMUM_EXPECTED_VERSION

pants.toml

[golang]
minimum_expected_version = <str>

default: 1.17

The minimum Go version the distribution discovered by Pants must support.

For example, if you set '1.17', then Pants will look for a Go binary that is 1.17+, e.g. 1.17 or 1.18.

You should still set the Go version for each module in your go.mod with the go directive.

Do not include the patch version.

Advanced options

asdf_bin_relpath

--golang-asdf-bin-relpath=<str>
PANTS_GOLANG_ASDF_BIN_RELPATH

pants.toml

[golang]
asdf_bin_relpath = <str>

default: bin

The path relative to an ASDF install directory to use to find the bin directory within an installed Go distribution. The default value for this option works for the go-sdk ASDF plugin. Other ASDF plugins that install Go may have a different relative path to use.

asdf_tool_name

--golang-asdf-tool-name=<str>
PANTS_GOLANG_ASDF_TOOL_NAME

pants.toml

[golang]
asdf_tool_name = <str>

default: go-sdk

The ASDF tool name to use when searching for installed Go distributions using the ASDF tool manager (https://asdf-vm.com/). The default value for this option is for the go-sdk ASDF plugin (https://github.com/yacchi/asdf-go-sdk.git). There are other plugins. If you wish to use one of them, then set this option to the ASDF tool name under which that other plugin was installed into ASDF.

cgo_c_flags

--golang-cgo-c-flags="['<str>', '<str>', ...]"
PANTS_GOLANG_CGO_C_FLAGS
