### 2.0.0-develop.4 / 2015-12-14

This versions makes the code documentation 100% 'A' grade on inch.
We have used inch and http://inch-ci.org to guide the priorities
on documentation production.

The grade 'A' (on inch) number of objects on master branch was 44,22% (153/346).
After this PR we have a 100% grade 'A' (344 objects).

There's already a inch-ci.org badge on README.md. And now it's all green!

We also bring some improvement on CodeClimate scores.

#### CHANGES SUMMARY

* PR #179 - Make inch happy. Grade "A" for the whole HighLine documentation. By Abinoam Jr. (@abinoam)
* PR #178 - Improve score on Code Climate by applying some refactoring. By Abinoam Jr. (@abinoam)
* PR #172 - Initial work on documentation by Abinoam Jr. (@abinoam)
  * Use yard
  * Use inch
  * New Readme file
* Fix #166 with PR #173 by (@matugm)


### 2.0.0-develop.3 / 2015-10-28

This version brings some improvements on documentation (switch to Yardoc).
This is the first 2.0.0-develop.x version to be release as gem.

### 2.0.0-develop.2 / 2015-09-09

(by Abinoam P. Marques Jr. - @abinoam)

#### NOTES

This version brings greater compatibility with JRuby and Windows.
But we still have a lot of small issues in both platforms.
We were able to unify/converge all approaches into using io/console,
so we could delete old code that relied solely on stty, termios, java api and
windows apis (DL and Fiddle).

Another improvement is the beginning of what I called "acceptance tests".
If you type ```rake acceptance``` you'll be guided through some tests
where you have to input some thing and see if everything work as expected.
This makes easier to catch bugs that otherwise would be over-sighted.

#### CHANGES SUMMARY

* Fix Simplecov - it was reporting erroneous code coverage
* Add new tests. Improves code coverage
* Extract HighLine::BuiltinStyles
* Try to avoid nil checking
* Try to avoid class variables (mis)use
* Fix RDoc include path and some small fixes to the docs
* Move HighLine::String to its own file
* Add HighLine::Terminal::IOConsole
  - Add an IOConsoleCompatibility module with some stubbed
    methods for using at StringIO, File and Tempfile to help
    on tests.
  - Any enviroment that can require 'io/console' will
    use HighLine::Terminal::IOConsole by default. This kind
    of unifies most environments where HighLine runs. For
    example, we can use Terminal::IOConsole on JRuby!!!
* Add ruby-head and JRuby (19mode and head) to Travis CI matrix. Yes, this
  our first step to a more peaceful JRuby compatibility.
* Add AppVeyor Continuous Integration for Windows
* Add _acceptance_ tests for HighLine
  - Use ```rake acceptance``` to run them
  - Basically it interactively asks the user to confirm if
    some expected HighLine behavior is actually happening.
    After that it gather some environment debug information,
    so the use could send to the HighLine contributors in case
    of failure.
* Remove old and unused files (as a result of relying on io/console)
  - JRuby
  - Windows (DL and Fiddle)
  - Termios
* Fix some small (old and new) bugs
* Make some more tuning for Windows compatibility
* Make some more tuning for JRuby compatibility

### 2.0.0-develop.1 / 2015-06-11

This is the first development version of the 2.0.0 series. It's the begining of a refactoring phase on HighLine development cycle.

#### SOME HISTORY

In 2014 I emailed James Edward Gray II (@JEG2) about HighLine. One of his ideas was to completely refactor the library so that it could be easier to reuse and improve it. I've began my contributions to HighLine trying to fix some of the open issues at that time so that we could "freeze" a stable version of HighLine that people could rely on. Then I've began to study HighLine source code with James' help and started to refactor some parts of the code. Abinoam P. Marques Jr. (@abinoam)

#### NOTES

* This release differs from current master branch by more than 180 commits.
* The main changes will be only summarized bellow (as there are many, and a detailed description of each is not productive).
* You could try `git log -p` to see all of them.
* During the last commits, all possible efforts were taken to preserve the tests passing status.
* 100% test passing gives you no guarantee that this new version will work for you. This happens for many reasons. One of them is that we don't currently have 100% test coverage.
* So, this version is not suitable for use in production.
* [Metric_fu](https://github.com/metricfu/metric_fu) and [Code Climate](https://codeclimate.com/github/abinoam/highline) were used here not to strictly "guide" what should be changed, but to have some way to objectively measure the progresses made so far.

#### CHANGES SUMMARY
* Extracted a lot of smaller methods from bigger ones
* Extracted smaller classes/modules from bigger ones, so they could be self contained with less external dependencies as possible, for example:
  * HighLine::Statement
  * HighLine::List
  * HighLine::ListRenderer
  * HighLine::TemplateRenderer
  * HighLine::Question::AnswerConverter
  * HighLine::Terminal
  * HighLine::Terminal::UnixStty
  * HighLine::Paginator
  * HighLine::Wrapper
* After extracting each class/module some refactoring were applied to them lowering code complexity

#### METRICS SUMMARY
Some of the metrics used to track progress are summarized bellow. Some of them have got a lot better as Flay, Flog and Reek, others like Cane haven't (probably because we didn't commented out the new code yet)

__CODECLIMATE__

* GPA: 3.60 -> 3.67 (higher is better)

__CANE__ - reports code quality threshold violations (lower is better)

* Total 92 -> 105
  * Methods exceeding allowed Abc complexity: 14 -> 10
  * Lines violating style requirements: 69 -> 72
  * Class definitions requiring comments: 9 -> 23

__FLAY__ - analyzes ruby code for structural similarities (code duplication - lower is better)

* Total: 490 -> 94

__FLOG__ - measures code complexity (lower is better)

* Top 5% average: 127.9458 -> 40.99812
* Average: 17.37982 -> 7.663875
* Total: 2158.5 -> 1969.6

__REEK__ - detects common code smells in ruby code (lower is better)

* DuplicateMethodCall: 144 -> 54
* TooManyStatements: 26 -> 30

  HighLine was silently swallowing error messages when ffi-ncurses gem
  was installed without ncurses present on the system.

* Added the ability to pass a block to HighLine#agree().

  adding support for Solaris.  (patch by Ronald Braswell and Coey Minear)

* Moved to a forked development/stable version numbering.

### 1.0.2

* Removed old and broken help tests.

  would show up in the default responses.

  Hashes filled with answers.  You can set +gather+ to a count of answers to
  collect, a String or Regexp matching the end of input, or a Hash where each
  key can be used in a new question.
* Added File support to HighLine.ask().  You can specify a _directory_ and a
  _glob_ pattern that combine into a list of file choices the user can select
  from.  You can choose to receive the user's answer as an open filehandle or as
  a Pathname object.

  Readline).

    menu solution.
  * Provided for total customization of the menu layout.
  * Allowed for menu selection by index, name or both.
  * Added a _shell_ mode to allow menu selection with additional details
    following the name.

  layout Arrays for you in any output in the modes <tt>:columns_across</tt>,
  <tt>:columns_down</tt>, <tt>:inline</tt> and <tt>:rows</tt>
* Added support for <tt>echo = "*"</tt> style settings.  User code can now
  choose the echo character this way.

  available.  Will return to old behavior (using "stty"), if "termios" cannot be
  loaded.

* Improved the default auto-complete error message and exposed this message

  make fetching passwords trivial.
* Fixed an auto-complete bug that could cause a crash when the user gave an
  answer that didn't complete to any valid choice.
* Implemented +case+ for HighLine::Question objects to provide character case
  conversions on given answers.  Can be set to <tt>:up</tt>, <tt>:down</tt>, or
  <tt>:capitalize</tt>.
* Exposed <tt>@answer</tt> to the response system, to allow response that are
  aware of incorrect input.
* Implemented +confirm+ for HighLine::Question objects to allow for verification
  for sensitive user choices.  If set to +true+, user will have to answer an
  "Are you sure?  " question.  Can also be set to the question to confirm with
  the user.

### 0.4.0

* Added <tt>@wrap_at</tt> and <tt>@page_at</tt> settings and accessors to
  HighLine, to control text flow.
* Implemented line wrapping with adjustable limit.

  by extension.)
* Added whitespace handling for answers.  Can be set to <tt>:strip</tt>,
  <tt>:chomp</tt>, <tt>:collapse</tt>, <tt>:strip_and_collapse</tt>,
