Release 1.0.0

Incompatible Changes

  • @bazel_skylib//:lib.bzl is removed. You now must specify specific modules via @bazel_skylib//lib:.bzl.
  • maprule.bzl is removed.

New Features

  • Added types.is_set() to test whether an arbitrary object is a set as defined by sets.bzl.

Release 0.9.0

New Features

  • common_settings.bzl: Standard data types for user defined build configuration. Common scalar build settings for rules to use so they don't recreate them locally. This fulfills part of the SBC design doc: https://docs.google.com/document/d/1vc8v-kXjvgZOdQdnxPTaV0rrLxtP2XwnD2tAZlYJOqw/edit#bookmark=id.iiumwic0jphr

  • selects.bzl: Add config_setting_group for config_setting AND/OR-chaining Implements https://github.com/bazelbuild/proposals/blob/master/designs/2018-11-09-config-setting-chaining.md.

  • Make sets.bzl point to new_sets.bzl instead of old_sets.bzl. new_sets.bzl and old_sets.bzl should be removed in the following skylib release.

  • run_binary: runs an executable as an action

    • This rule is an alternative for genrule(): it can run a binary with the desired arguments, environment, inputs, and outputs, as a single build action, without shelling out to Bash.
    • Fixes bazelbuild#149

  • New native_binary() and native_test() rules let you wrap a pre-built binary in a binary and test rule respectively.

    • native_binary() wraps a pre-built binary or script in a *_binary rule interface. Rules like genrule can tool-depend on it, and it can be executed with "bazel run". This rule can also augment the binary with runfiles.
    • native_test() is similar, but creates a testable rule instead of a binary rule.
    • Fixes bazelbuild#148

  • diff_test: test rule compares two files and passes if the files match.

    On Linux/macOS/non-Windows, the test compares files using 'diff'.

    On Windows, the test compares files using 'fc.exe'. This utility is available on all Windows versions I tried (Windows 2008 Server, Windows 2016 Datacenter Core).

    See bazelbuild/bazel#5508, bazelbuild/bazel#4319

  • maprule: move functionality to maprule_util.bzl. maprule_util.bzl will benefit planned new rules (namely a genrule alternative).

This release is tested with Bazel 0.28
