For this release, we have had 46 developers from around the world contributing
over 150 commits in the last 9 weeks.

Improving the API available for bear writers is one of the areas we've focused
on for this release, with several new and exciting features. General performance
has also been improved heavily with some major changes under the hood. The
documentation has also been worked on, with an emphasis on user-friendliness
and design.

There have also been major internal changes in preparation for the complete
decentralization of bears, which would allow the installation of individual
bears.

Below are some of the important changes introduced for this release:

New Features

  • coala now supports syntax highlighting in results!
  • Questions are now printed in color; this will improve visibility when a lot
    of text is written to the screen.
  • coala-json now supports --show-bears and --filter-by-language
  • Added a --show-capabilities flag that displays the types of issues coala
    can detect and fix for a particular language.
  • Display the line number when a line is missing; this could happen if a bear
    that had run previously overwrites it.

For Bear Writers

  • Bears now have a new REQUIREMENTS attribute which will be used to
    automatically resolve bear dependencies. This includes:
    • Native requirements (from package managers such as apt-get, dnf, pacman, ...)
    • Conda requirements
    • Python requirements through pip
    • go requirements
    • Ruby requirements through gem
    • NodeJS requirements through npm
    • RScript requirements
    • Julia requirements
  • Language independent documentation parsing routines: these can be used to
    make bears for linting documentation without having to worry about the
    language.
  • coalang now supports C, C++, CSS, Java, Python3 and Vala.
  • A new bear creation tool has been released: with this tool, it's easier than
    ever before to create external linter based bears for coala!
  • A new ASCIINEMA_URL attribute has been added to bears. This should
    contain an URL to an asciinema video displaying the bear's capabilities in action.
  • Bear results may now have a confidence parameter: this is supposed to
    quantify the confidence, on a scale of 1 to 100, the bear has when flagging results.
  • A deprecate_settings decorator has been created to deprecate old,
    unsupported bear parameters. Please see
    here
    for an example usage.
  • Code Simplification has been added to the set of possible fixes that
    bears can offer.

Bug Fixes

  • Fixed an issue where errors were generated for lines containing only a
    single tab character. Issue #2180
  • Fixed an issue with question where stray escape characters may be present.
    Issue #2546
  • Group questions about missing values in a coafile by bears.
    Issue #2530
  • An issue where an exception was raised wrongly when the same diff was
    generated multiple times has been fixed.
    PR #2465

Performance

  • Caching is now enabled by default. This is a huge performance improvement
    for HDD users - we've seen a 2x improvement when coala is run on coala.
    To disable caching run coala with the --disable-caching flag.
  • An issue where coala takes over 2 seconds to print the help manual through
    --help has been fixed.
    Issue #2344
  • A small performance improvement from reusing already loaded file contents.

Documentation

  • A complete overhaul to the README page with a focus on design and
    readability.
  • A new FAQ page has
    been created.
  • Various other documentation pages have been improved with new resources,
    better explanations, and some corrections.
  • The whole documentation has been moved to a
    separate repository.
    Please file any documentation related issues over there.

Regressions

  • Dropped Python 3.3 support

Internal Changes

  • There has been a shift of several modules from coala to
    coala-utils. This includes the whole
    StringProcessing library, ContextManagers, and some decorators.
