Release Notes

bazelbuild/bazel-gazelle

v0.20.0

Compare Source

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.
