v0.24.0

This release requires rules_go 0.29 to support the retirement of go_tool_library.

IMPORTANT

This release includes many new dependencies. Please be sure that your own workspace's dependencies are declared PRIOR to gazelle_dependencies(), or else they may be overridden. See the prompt block comment in the boilerplate below.

v0.23.0

Changes

• Go
  • CXXFLAGS and CPPFLAGS #cgo directives are separated into cxxopts and cppopts attributes, respectively. Thanks @otan.
  • Dependencies on mapped kinds are now supported. Thanks @robfig.
  • The gazelle rule now supports the update-repos command.
  • The gazelle rule now has a data attribute and expands $(location) within arguments.
  • go_repository's build_naming_convention is now considered when resolving external dependencies. If a repository already has build files, this attribute may be set to indicate which naming convention it follows.
  • embedsrcs attributes are generated for packages that contain //go:embed directives.
• Protobuf
  • proto_strip_import_prefix may be set in the root build file. Thanks @linzhp.

v0.22.2

Compatibility

• Gazelle no longer depends on the deprecated go_rule function from rules_go, which will be removed in 0.25. This should improve compatibility with future versions.

v0.22.1

Bug fixes

Go

• The version of rules_go may now be inferred from WORKSPACE if the repository io_bazel_rules_go hasn't been fetched yet.
• The gazelle_binary rule should now work correctly with previous versions of rules_go.
• In the import and import_alias naming conventions, dots will be replaced with underscores in generated test names. This avoids generating targets that have the same names as source files.
• update-repos -from_file=go.mod should no longer fail mysteriously when go.mod has a replace directive that uses a relative path. Local replacements are still not supported though. (thanks @dragonsinth)

gazelle_dependencies()

v0.22.0

Changes

• The Go extension can now generate targets with a new naming convention.
  • In new projects, by default, a library will be named foo if its import path ends with foo instead of go_default_library. Similarly, a test will be named foo_test instead of go_default_test.
  • Gazelle will attempt to detect the naming convention used in existing projects, so it shouldn't unexpectedly change the naming convention.
  • To specify the naming convention explicitly, use the # gazelle:go_naming_convention directive or the -go_naming_convention flag. Valid values are import, go_default_library, and import_alias. Gazelle will rename existing targets the next time it runs after a change.
  • go_repository uses the import_alias naming convention by default, so either the old or new names may be used.
  • Thanks to @tomlu for implementing this.
• Added # gazelle:go_generate_proto directive, which instructs the Go extension whether to generate go_proto_library rules for proto_library generated by the proto extension (thanks @linzhp).
• Improved Windows compatibility (thanks @tomlu).
• Language extensions can now provide dependency resolution for other extensions by implementing the resolve.CrossResolver interface. This is now used for resolve proto imports in Go (thanks @blico).
• In the update-repos command, the -build_directives flag may be used to set the build_directives attribute on generated repositories (thanks @Helcaraxan).
• In the update-repos command, new rules and macros will be inserted higher in WORKSPACE, above go_rules_dependencies and gazelle_dependencies if possible, to make it easier to override indirect dependencies.

Compatibility

• gazelle_binary no longer supports mode attributes such as goos, race, and gotags. These depended on internal implementation details in rules_go. If you need to build a gazelle_binary for a platform other than the host, use command-line flags such as --platforms and --@io_bazel_rules_go//go/config:race or use a transition.

gazelle_dependencies()

v0.21.1

Bug fixes

• Fixed visibility for Go libraries in internal directories. Previously,
  internal visibility was applied to packages in subdirectories of internal,
  directories, not internal directories themselves. Thanks to @robfig.
• go_repository no longer runs cat, and genrules are replaced with native
  rules to reduce dependence on msys2 on Windows. Thanks to @tomlu.
• Cases in select expressions are no longer emitted for platforms that aren't
  supported by the current version of rules_go.

v0.21.0

• # gazelle:exclude directives now accept patterns with * and ** wildcards. (thanks @kalbasit)
• The -lang flag may now be used to select which language extensions should be run. By default, all extensions Gazelle was built with will run. (thanks @robfig)
• Attribute matching now works on string slice attributes, not just strings. This is now used to match proto_library rules with one or more sources in common with the generated rule, even if the rule has been renamed. (thanks @linzhp)
• Many bugs have been fixed. Thanks to everyone who helped out!

v0.20.0

General changes

• When update-repos is invoked with -to_macro, Gazelle will add a call to the macro and a # gazelle:repository_macro directive to WORKSPACE if neither is present.

Go changes

• Gazelle will avoid generating duplicate go_repository rules when two module paths differ only in case. Thanks to @linzhp.
• When deriving a repository name from an import path, all non-word characters will be replaced with underscores, not just dots and slashes. Consecutive non-word characters will be collapsed to a single underscore. Thanks to @carnott-snap.
• Imported repository rules are now sorted.

Proto changes

• Gazelle will add load statements for proto_library to comply with --incompatible_load_proto_rules_from_bzl. Thanks to @Yannic.
• Fixed a bug recognizing services in .proto files. Thanks to @asv.

v0.19.1

Changes

• Rule names are now included in go_repository stderr output.
• Environment variables SSL_CERT_FILE and SSL_CERT_DIR are passed through to tools used by go_repository.
• The list of standard packages is correctly updated for Go 1.13.
