0.5.0

Features

• go_repository replaces new_go_repository for dependencies with
  and without BUILD or BUILD.bazel files. go_repository will
  generate these files using Gazelle if they are not already present.
• Import paths may be specified explicitly using the importpath in
  go_library. This allows for Go subtrees that aren't at the top of
  a repository. It also allows flat BUILD files.
• Gazelle generates BUILD files for multiple platforms. Sources with
  build constraints (tags or filename suffixes) and dependencies
  imported from them are now compiled conditionally using select.
• Link stamping in multiple packages is now supported via the x_defs
  attribute. x_defs may now contain values wrapped in braces (for
  example: {VAR}) which are replaced with values from the workspace
  status files.
• Rules are substantially cleaned up and organized. Assemble, compile,
  and link actions are rewritten in Go, avoiding incompatibilities and
  quoting problems with Bash.
• Preliminary support for toolchains.

Bug fixes

• cgo_library now allows sources in multiple directories.
• cgo_library no longer assumes srcs is a list (it can now include
  select calls).
• go_binary and go_test no longer expose .a files in outputs.
• All rules now allow target names with slashes.
• If multiple packages are present after applying build constraints,
  Gazelle will generate BUILD files for the package matching the
  directory name. If there is no match, Gazelle will report an error.
• Gazelle is much faster when running in external mode on repositories
  with lots of external dependencies.
• Gazelle no longer removes # keep comments from existing sources.
• Many more...

0.4.4

This release is a cherry-pick of #428 on top of 0.4.3. This adds support for the darwin_x86_64 cpu value, which will become standard in Bazel soon.

0.4.3

Features

• Upgraded to Go 1.8.1 and provided backward compatibility for tests in 1.7.5.
• Support for build constraints (build tags and filename suffixes) in go_library, cgo_library, go_test, and go_binary. You can now add all your sources to your rules, and they will be filtered during compilation.
  • Note: Gazelle also filters sources with build constraints. This behavior will be removed when #339 is fixed.
• go_repositories now supports custom Go versions. Versions can be specified with a simple version string (e.g., "1.8.0") or by declaring a separate Bazel repository and providing that through the go_linux or go_darwin attributes.
• go_repository now supports vcs and importpath attributes. This enables repositories with different URLs and import paths.
• gc_goopts and gc_linkopts attributes can be used to pass additional options to the compiler and linker.
• protoc and protoc_gen_go can now be overridden in go_proto_library. Also added an ignore_go_package attribute.
• Gazelle now adds a data dependency on testdata directories.

Bug fixes

• Fixed repositories rules that depended on the real names of repositories. This broke when one of our dependencies (github.com/bazelbuild/buildifier) was renamed to buildtools. A quick fix was backported to 0.4.2 and 0.3.4.
• Fixed -mode diff in Gazelle. It now produces a regular textual diff.
• Gazelle no longer attempts to rename files with -mode fix or -mode print.
• Gazelle can now find # gazelle:ignore comments that aren't at the top of a file.
• Bash scripts generated by rules are now executed as commands instead of executable files. This is required on Windows.
• Fixed an infinite recursion issue on Windows.
• data files are now propagated transitively across dependencies.

0.4.2

This release fixes a break which was caused by github.com/bazelbuild/buildifier being renamed to buildtools. The following changes are cherry-picked:

• #319 go_repository: add importpath and vcs flags. This allows us to have separate import paths and remote URLs for repositories.
• #362 Fetch buildifier from new location. This allows the buildifier zip to be extracted with the new name.

0.4.1

Features

• #266 - gazelle no longer reformats files with "# gazelle:ignore".
• #274 - cgo libraries are now built with -pthread or -mthreads
