  🚀 This release was brought to you by 65 contributors contributing 141
  commits.

  🚀 The name of this release is BrewBear to highlight the improvements made
  to our dependency management system, including the addition of brew
  👌 support for mac users. Mac has been an officially supported platform for
  a long time and we would like to draw attention to this often overlooked
  👍 fact. Support has also been added for conda and cargo allowing bears
  👕 which use linters available from those package managers to manage their
  dependencies.

  🎉 Initial next generation core code has been merged and will be integrated
  🚀 over the coming releases. Until then, please use the current API.

  🚀 We have added a release candidate system to our release process to allow
  🚀 users to easily test changes in the latest pre-release version of coala.
  📦 Instructions for obtaining the rc package will be posted for each
  🚀 minor/major release to the coala gitter channel, blog, and twitter. We
  encourage all users interested in checking out new features or helping
  🚀 to test these pre-releases on their projects. If you do find a
  🚀 regression in a release candidate, please report it to the issue tracker
  with the word Regression somewhere in the title.

  💥 Breaking Changes

  • coala now exits with a non zero exit code when error level results
    🌲 are logged. If you relied on coala logging in scripts or other
    automated systems please modify them to work with the new behavior.
    ✅ You can find all exit codes here.
    PR #3905

  General

  • 📜 Section Inheritance had been added to the coafile parsing. With this
    🔄 change we are deprecating implicit default section inheritance.
    Instead, you can now have definite section inheritance by using the
    👍 . in the section title. Append operators are now supported
    👍 allowing addition of values to inherited section. See the
    Explicit Setting Inheritance section of the
    ✅ docs
    for a syntax example and detailed instructions
  • The section name cli is reserved for cli arguments and should not
    🔧 be used in the coala configuration file (coafile). If you are
    🔧 currently using it in a configuration file, coala will warn you.
  • coala now outputs absolute file paths when a bear fails. This should
    👉 make debugging bear failures easier when using custom bears.

  Usability

  • A new placeholder, source_lines, has been added to the coala
    --format option. Use it to output the affected lines in the source
    file when a result occurs.
  • Bears are displayed alphabetically when listed using --show-bears.
  • ⚠ coala outputs a warning if a setting is overridden in the same
    section since this is probably not what the user intended.
  • --format is handled correctly when --ci is specified, outputting
    formatted output without asking questions. Issue#3999
  • coala will report the version of the dependency required when the
    🔖 version check fails. Issue#3982

  Bear Developers

  • 👕 @linter decorator works with global bears. See our bear writing
    👕 docs
    for more information on how to write a global bear with the
    👕 @linter decorator.
  • Bear.DownloadCachedFile raises exceptions when the download fails.
    👀 Please see the requests library
    📄 docs
    for a complete list of possible exceptions that will need to be
    🖐 handled.
  • 🗄 The deprecate_settings decorator now supports multiple
    🗄 deprecations of the same setting. Issue #3537
  • 👀 A new SEE_MORE attribute has been added to the Bear class. Use
    it to attribute (usually by linking the main page) the original tool
    👕 in linter bears.
  • 👕 Unified Diff support has been added to the Diff result, linter and
    display mechanisms.

  🛠 Bugfixes

  • 🛠 Caching has been fixed to work correctly. Results are only cached
    when a bear successfully runs. A bear which fails in the middle of a
    ⚙ run will not have a result cached anymore. This should make flushing
    the cache manually mostly unnecessary for end users. PR#3722
  • Non-optional settings check settings from dependent bears now.
    Previously, it would error because the dependency would not have its
    settings satisfied. Issue#3149
  • The Result object now handles None values of TextPosition
    properly. Previously, it would return arbitrary results which would
    impact bear authors. Issue#3094
  • A few problems when using coala in systems with incomplete locales
    🐳 data have been fixed. This was common in Docker containers. Issue#3906

Previous changes from v0.11.0.rc2

• • 🛠 Fixed critical section inheritance bug where sections with different capitalization would not inherit. Issue #4182
